Description

Message intercommunicating method, system and message intercommunication entity

Technical field

The present invention relates to communication technical field, particularly the message intercommunicating method of Session initiation Protocol (SIP, Session InitiationProtocol) message and traditional short message intercommunication, and system message interconnection entity.

Background technology

IP Multimedia System (IMS; IP Multimedia Subsystem) is the subsystem of 3GPP at the support IP multimedia service of stage 5 (Release5) version proposition; Its core characteristics be adopt Session Initiation Protocol and with the independence that inserts; Therefore IMS is a multimedia control/calling controlling platform on the IP territory; Support conversation class and non-conversation class multimedia service, for the multimedia application in future provides a general business to enable platform, it is to complete IP network (All IP Network) business the essential step of system evolution to be provided.Along with rise and development based on the access technology of IMS; How the messaging service with existing traditional mobile terminal is converted into the business that the IMS terminal can provide; On the basis of reusing existing mobile network short message business function entity and agreement as far as possible; Realization is based on the SIP based information series business of IMS framework; Instant message (Immediate Messaging) and conversation-based message (Session based messaging) like definition among the 3GPP (third generation gpp standardization body); And Session initiation Protocol (SIMPLE, SessionInitiation Protocol for Instant Messaging and Presence Leveraging Extensions) and traditional messaging service to instant messages and expression expansion of OMA definition; Like the Short Message Service (SMS) of 3GPP definition and the business intercommunication between the Enhanced Message Service (EMS), also be a target of each operator's question of common concern and 3GPP standardization body.

Because the EMS of 3GPP definition belongs to the SMS that strengthens type, for for simplicity, the short message in traditional C as herein described/PS territory has comprised the messaging service of SMS and two forms of EMS simultaneously.

Fig. 1 is the network frame that traditional short message service is realized at the use IP terminal of present 3GPP proposition, and wherein Short Message Entity (SME), Short Message Service Center (SM-SC), mobile switching centre's gateway/short message intercommunication mobile switching centre (GMSC/SMS-IWMSC), home signature user server/attaching position register (HSS/HLR) are that existing mobile network is realized the functional entity that short message (SMS) is professional.SM-SC is used for storing short message; When GMSC is used for terminal reception short message, to HSS/HLR inquiry routing iinformation; SMS-IWMSC carries out authentication etc. when being used for the terminal and sending SMS message.The short message service center that uses in the network at present; All be that collection SM-SC, GMSC and three of SMS-IWMSC are the equipment of one; These three functional entitys are not realized as independent physical equipment; So promptly represent hereinafter, the equipment of SM-SC, GMSC and three one of SMS-IWMSC like no specified otherwise short message service center or traditional short message service center.HSS/HLR is used to store user's data information, comprises user's signing service data and routing iinformation.Network frame shown in Figure 1 also comprises charging network management function/charging data function (CGF/CDF) and Online Charging System (OCS); CGF/CDF is used to collect the also ticket information of the offline charging of process user; Be passed to the charging center then; OCS is used to collect the also ticket information of process user online charging, is passed to the charging center then.Among Fig. 1; IP message gateway (IP-Message-GW; Also be designated as IP-SM-GW among hereinafter and the figure) be used to realize the communication between IP client and the GMSC/SMS-IWMSC; Need carry out IP network messaging protocol (promptly based on the IP-based communication protocol of using between IP terminal and the IP-Message-GW) and existing WCDMA/GSM network short-message protocol (is the MAP that uses between IP-Message-GW and the GMSC/SMS-IWMSC; Be similar in the implementation procedure of present short message the MAP between MSC and SGSN and the GMSC/SMS-IWMSC) between intercommunication.When the user who supports IP to insert uses short message service; Must be registered to earlier on the IP-SM-GW; Registered and the IP-SM-GW address of IP-SM-GW notice this user of HSS, it is IP Connected that HSS preserves User Status, and stores the IP-SM-GW address of corresponding user's registration.

In existing standard; IMS messaging services and traditional short message service have been proposed based on the message intercommunication on the transportation level; Wherein, IP message gateway (IP-SM-GW) has been realized the message that the encapsulation of short message will be conciliate after encapsulation process also will be handled is transmitted accordingly, simultaneously as the short message bearing interconnection gateway between IMS territory and traditional circuit/grouping (CS/PS) territory; The IP message gateway is for the message that receives, and can also be provided with in the preference according to the strategy of predetermined strategy such as operator and user to select corresponding territory to carry out route to message.

Be that follow-up narration is convenient, below the information series business based on SIP in the IMS territory (or being called IMS core net (IMS core)) be called sip message, the short message service in traditional C/PS territory is called traditional short message.

Shown in Figure 2 is existing based on sip message and the traditional short message register flow path sketch map in the transport layer intercommunication.

Step 1, subscriber equipment (UE) are that IP client is set up the IP connection.

Step 2, after IP connected foundation, the user was registered on serving-call session control function (S-CSCF) entity through the IMS register flow path.

Step 3, in registration process, the initial filter criteria that the S-CSCF inspection is downloaded from HSS, this initial filter criteria is to stipulate in the existing protocol, no longer details here.This initial filter criteria is called first initial filter criteria among this paper.

Step 4, after completing successfully the IMS registration, based on first initial filter criteria, S-CSCF notice IP message gateway user's login state.

Step 5, the IP message gateway returns success response to S-CSCF.

Step 6, IP message gateway are sent the third-party registration request to HSS.

The information that step 7, HSS storage receive, and return the register response of IP-IWF (IPinterworking function) to the IP message gateway, comprising providing service relevant subscription data.

So far, UE is registered on the IP message gateway, and the IP message gateway has obtained the subscription data relevant with service from HSS.

After registration finishes, as shown in Figure 3 based on sip message and traditional short message intercommunication processing messages termination (MT) flow process on transportation level.Referring to Fig. 3,

Step 1, the user is registered on the S-CSCF through the IMS register flow path.

Step 2, SM-SC is forwarded to SMS-GMSC with the short message that receives.

Step 3, SMS-GMSC sends the routing iinformation request to HSS, HSS/HLR transmits this and asks to the IP message gateway, the IP message gateway returns the routing iinformation response message to SMS-GSMC, in this message the IP message gateway with the address of oneself as routing iinformation.

Step 4, SMS-GMSC according to the routing iinformation in the routing iinformation response message that receives to IP message gateway forwards short message, this process be similar to SMS-GMSC in traditional short message transmit mechanism with forwards to MSC or SGSN.

After step 5, IP message gateway receive the short message of SMS-GMSC forwarding, send route requests, obtain the address information of MSC and/or SGSN from HSS/HLR to HSS/HLR.

Step 6, the IP message gateway is carried out network domains and is selected, and selects suitable path to carry out the transmission of short message based on the strategy of predetermined strategy such as operator and user's preference.

The route that hypothesis is selected in the present embodiment is the IMS territory.

Step 7, if the route of selecting is the IMS territory, the IP message gateway is according to the called subscriber's in the short message that receives telephone number (MSISDN), converts this MSISDN the form of TEL-URI to, and is encapsulated in short message in the sip message body and is forwarded to S-CSCF.

Step 8, S-CSCF transmits the sip message that has encapsulated short message to user terminal.

Step 9, user terminal receives response of successful to the S-CSCF return messages.

Step 10, S-CSCF receives response of successful to IP message gateway return messages.

In above-mentioned IMS network and legacy network message business intercommunication scheme; The IP message gateway has been realized traditional short message and based on the bearing interconnection gateway of sip message, and promptly its is encapsulated in the message body in the SIP signaling and is sent to the called subscriber via IMS core net (IMScore) being carried on short message in MAP (MAP) signaling; In addition, the message body short message that it will be carried in the SIP signaling carries out decapsulation, converts the MAP signaling to and via the legacy network territory, is sent to the called subscriber like the CS/PS territory, and download relevant routing iinformation from HSS, carries out the forwarding of message.In addition; The IP message gateway has also been realized network domains selection and message routing functionality; Make short message can always be sent to the IP message gateway; And after according to carrier policy and user preference selected corresponding territory being set by the IP message gateway,, short message is issued to called user terminal thereby being routed to corresponding territory.

Intercommunication on this transportation level, promptly complete intercommunication based on encapsulation format only can realize when the IMS user terminal is also supported traditional short-message protocol stack simultaneously.It is thus clear that the intercommunication on this transportation level just with a kind of carrying of SIP as short message, is not real sip message and the intercommunication between traditional short message.And short-message protocol belongs to the agreement that need support when messaging service is used at terminal among the mobile network, for then possibly not supporting the agreement of the messaging service that the mobile network defines in the IMS terminal in the fixed network, and only supports based on sip message professional.In addition; In the process of network evolution; The IMS terminal of subsequent movement network also possibly only supported based on sip message professional; And do not support traditional short message service, in this case, just can't realize based on the IMS user terminal of sip message business and the intercommunication of the information series business between the legacy user terminals.

Embodiment

Thinking of the present invention is: system, method and the message intercommunication entity of a kind of IMS network and legacy network message class business intercommunication are provided, are applicable to that the IP client based on the IP access to mobile network uses the situation based on the information series business in IMS territory.According to the present invention; Network uses an entity SMIAS (Short Message/IMS messaging interworking Application Server) who is used for message intercommunication to carry out based on the message of SIP and the authentication of legacy network message interworking service the storage forwarding capability of the conversion of message format and message.Here, SMI AS can be a network entity that increases newly, also can be the newly-increased functional module on the existing network entity, and it provides service through user's third-party registration for the user.The user only can not support under the SMS messaging protocol stack situation in intercommunication of service aspect of having contracted (Service level interworking) and current user terminal that S-CSCF just can initiate third-party registration to SMI AS.

Because what the present invention mainly solved is the problem of IMS network with traditional internet message class business intercommunication, therefore hereinafter be primarily aimed at one of calling and called and be user in the IMS network, another is user's in the legacy network a situation.

Below in conjunction with accompanying drawing and specific embodiment the present invention is explained further details.

Execution mode one:

SMI AS and IP-SM-GW are two self-existent entities of difference.

In the initial flow process of the IMS of this scheme domain message (IMS MO flow process); The user arrives S-CSCF through the IMS territory with forwards; S-CSCF is according to initial filter criteria; If be routed to message on the SMI AS, then SMI AS is being traditional short message format to following message conversion based on SIP of service authorization case of successful, and issues the message after the format conversion to traditional short-message system.Otherwise S-CSCF transmits by the requirement that has the IMS territory now the message based on SIP.

At this, the initial filter criteria in the MO flow process is called second initial filter criteria.The inspection of this second initial filter criteria comprises: check whether the ability characteristics sign feature tag that said sip message carries is the IMS message of encapsulation; Or whether the contracted interworking service of service aspect of inspection calling subscriber; Or whether the message identification of checking the interchange service identification CSID that sip message carries is the intercommunication class business of service aspect; If one of them is for being then said sip message to be routed on the said SMI AS.

In the IMS of this scheme domain message termination process (being IMS MT flow process); The IP message gateway is equivalent to a classes of messages router; It has received after the short message of traditional route entity forwarding, and to HSS inquiry routing iinformation, HSS only returns the address of MSC and/or SGSN.The address information and the MSC that receive and/or the address of SGSN about IMS territory of IP message gateway through in third-party registration, obtaining carried out the selection in territory according to the strategy of predetermined strategy such as operator and user's preference.If what select is the IMS territory, the IP message gateway is encapsulated in short message in the sip message body, and transmits short message to S-CSCF.S-CSCF is according to initial filter criteria; Can not support under the SMS messaging protocol stack situation like contracted Service level interworking (intercommunication of service aspect) and current user terminal of user; Be routed to message on the SMI AS; SMI AS carries out decapsulation to sip message and obtains traditional short message, and issues traditional short message conversion Cheng Chun based on the form of sip message.Otherwise S-CSCF just transmits the message based on SIP of encapsulation by prior art.At this, the initial filter criteria in the MT flow process is called the 3rd initial filter criteria.

Shown in Figure 4 is configuration diagram according to sip message and traditional short message intercommunication of the embodiment of the invention one.It comprises traditional short-message system, IMS core net, IP message gateway, user terminal, and the newly-installed message intercommunication entity SMI AS that is used to carry out the message format conversion of the present invention.

Be the E/Gd interface between SMI AS and the IP-SM-GW, the ISC interface that defines through 3GPP links to each other with IMScore, and selected agreement is a Session Initiation Protocol.SMI AS can be a network entity that increases newly, also can be the newly-increased functional module on the existing network entity.

According to network architecture shown in Figure 4; When SMI AS separates with the IP message gateway; The register flow path of the intercommunication of the IMS network user and traditional network user's information series business service aspect is as shown in Figure 5, and the third-party registration of IP message gateway and SMI AS does not have the branch of sequencing in this register flow path:

Step 1, the IP that UE is established to the IMS territory connects.

Step 2, UE sends the IMS register requirement to S-CSCF, wherein carries user's ability characteristics sign (feature tag), whether supports traditional short message service to be used for identifying subscriber terminal, promptly whether supports the SMS/EMS messaging service.

Step 3-7 carries out existing SMSIP register flow path, promptly with Fig. 2 in step 3-7 identical.

Step 8, S-CSCF carries out the inspection of second initial filter criteria.

Step 9; Based on initial filter criteria; If this user terminal of the feature tag that user terminal carries indication can not support that traditional short message service is the SMS/EMS messaging service, and the contracted interworking service of service aspect of user, then S-CSCF transmits register requirement to SMI AS.

Step 10, SMI AS returns success responds SIP 200OK message to S-CSCF, shows the third-party registration success.

Step 11, SMI AS initiates register requirement to HSS.

Step 12, HSS preserves the address of SMI AS and the relevant information that receives, and returns success response to SMI AS.

So far, UE successfully registration respectively in IP-Message-GW and SMI AS.

Referring to Fig. 6, after UE successfully registered in IP-Message-GW and SMI AS, the intercommunication on sip message and the traditional short message service service aspect was as shown in Figure 6 in the flow process of IMS-MO (message in IMS territory is initial):

Step 1, according to the IMS register flow path, UE is registered among the S-CSCF, and here, for simplicity, other network entities among the IMS core such as I-CSCF and P-CSCF do not show in the drawings; And according to the third-party registration flow process, UE is registered on IP message gateway and the SMI AS.

Step 2, UE sends to the message based on SIP among the S-CSCF through the IMS territory.

Step 3, S-CSCF carries out the inspection of second initial filter criteria to what receive based on the message of SIP, to determine whether and need said message be sent to SMI AS.This inspection comprises S-CSCF inspection called subscriber's sign; (in caller is IMS user if the called subscriber is for the form of TEL-URI; Called is under the PS/CS user situation), S-CSCF carries out ENUM (Telephone NumberMapping working group) inquiry to the called subscriber.If the ENUM successful inquiring, promptly TEL-URI can successful conversion become under the SIP-URI situation, and S-CSCF is the IMS territory that sends to the called end user based on the message of SIP, and transmission flow is consistent based on the send mode of the message of SIP with prior art, repeats no more here; If ENUM inquires about failure, S-CSCF continues to check whether the message based on SIP is whether traditional short message format, the calling terminal UE that encapsulates has been registered to the first-class information of SMI AS.

Step 4; Under the situation of ENUM inquiry failure; Based on initial filter criteria, if not being traditional short message format and the calling terminal UE that encapsulates, sip message has not been registered on the SMI AS, perhaps user preferences or carrier policy require to carry out under the situation such as intercommunication of service layer; Then S-CSCF arrives SMI AS to the forwards based on SIP, and execution in step 5 afterwards; Based on the message of the SIP form for traditional short message of encapsulation, then by prior art, promptly S-CSCF is routed to the IP message gateway to the message based on SIP else if, by the IP message gateway to carry out transmitting after the decapsulation follow-up repeating no more based on the message of SIP.

Step 5, SMI AS carries out Authorized operation to interworking service and checks that promptly user signing contract information is to show user's this business of whether having contracted, if authorize successfully; Whether SMI AS inspection sip message body can be converted into traditional short message by structure; If convert sip message to traditional short message format, the forwards behind the format transformation to traditional short-message system; Accomplish follow-up repeating process by traditional short-message system, otherwise SMI AS returns failure reporting to S-CSCF.

Step 6 after SMI AS receives the report of the SMS message sink that the conventional message system returns, transmits report with short message and converts into accordingly based on sip response message.

Step 7-8, the sip response message after SMI AS will change sends to calling UE through the IMS network.

Here, the sip message in the step 2 can also comprise CSID, and at this moment, the inspection of second initial filter criteria of step 3 can also comprise according to CSID confirms whether the contracted interworking service of classes of messages of user.

In addition, the step 3 among Fig. 6～5 also have a kind of possible implementation to be:

Step 3 '; S-CSCF carries out the inspection of second initial filter criteria to what receive based on the message of SIP; This inspection comprises whether the ability characteristics sign (feature tag) that this sip message carries is pure IMS message "+g.oma.sip-im "; Or the IMS message of encapsulation "+g.3gpp.smsip "; Or whether the contracted interworking service of service aspect of inspection calling subscriber, or whether the message identification of the interchange service identification (CSID, Communication service identity) that carries of inspection sip message is the intercommunication class business of service aspect etc.

Step 4 ', the feature tag that carries when sip message is during for the IMS message of "+g.3gpp.smsip " i.e. encapsulation, and S-CSCF is routed to sip message on the IP message gateway, and follow-up processing procedure is identical with prior art; Other three kinds of situation, S-CSCF is routed to sip message on the SMI AS of caller network.

Step 5 '; The SMI AS of caller network judges whether that according to calling subscriber's preference and carrier policy needs serve the intercommunication of aspect, and have three kinds of possible situation this moment: need the service aspect intercommunication, handle, need not serve the aspect intercommunication by default situations.

The intercommunication of capable service aspect if desired; Then the SMI AS of caller network authorizes interworking service; If authorize successfully; The SMI AS of caller network becomes traditional short message format to the message conversion based on SIP, is forwarded to traditional short-message system to the message of format transformation, accomplishes follow-up repeating process by traditional short-message system.

Handle by default situations if desired, then the SMI AS of caller network selects the called territory network that sip message issues according to called subscriber's sign.If the called subscriber is the form of TEL-URI, the SMI AS of caller network can be to carry out issuing of message through the IMS territory or through the CS/PS territory according to the number segment information of self-configuring or result's selection of ENUM (TelephoneNumber Mapping working group) inquiry.

If the territory of selecting message to issue is the CS/PS territory; The SMI AS of caller network authorizes interworking service, if authorize successfully, the SMI AS of caller network becomes traditional short message format to the message conversion based on SIP; The forwards of format transformation to traditional short-message system; Accomplish follow-up repeating process by traditional short-message system, if authorize not success, the SMI AS of caller network returns the S-CSCF of failure reporting to the caller network; If the territory of selecting message to issue is the IMS territory, forward the message to the called IMS network by prior art.

If need not serve the aspect intercommunication; What then SMI AS selected according to the result of the number segment information of self-configuring or ENUM inquiry is the IMS territory; Forward the message to the called IMS network by prior art,, then return the S-CSCF of failure reporting to the caller network if SMI AS can not select the IMS territory.That is to say that if need not serve the aspect intercommunication, then SMI AS can not select the CS/PS territory, can only option IMS territory issuing message, select in the IMS territory to return failure reporting when unsuccessful.

Be appreciated that; Above-mentioned steps 5 ' is expressed to content to be: after SMI AS receives sip message; With the message conversion based on SIP that receives is before traditional short message format; Further comprise: SMI AS judges whether the intercommunication of the aspect of need serving, and the said message conversion based on SIP that will receive again if desired is traditional short message format.

Above-mentioned SMI AS judges whether that the foundation of the intercommunication of the aspect of need serving comprises: determine whether that according to calling subscriber's preference or carrier policy needs serve the intercommunication of aspect; Perhaps, when said SMI AS confirms that the called IMS territory is unreachable, confirm the intercommunication of the aspect of will serving.

Have again; After SMI AS confirms to serve the intercommunication of aspect; With the message conversion based on SIP that receives is before traditional short message format; Can further include: SMI AS authorizes interworking service, authorize successfully after, the message conversion based on SIP that will receive again is traditional short message format.

In addition, IP message gateway or SMI AS can also be used for the charging bill generating run of interworking service in the above-mentioned MO flow process.

After UE registers in IP-Message-GW and SMI AS, traditional messaging service and again can be divided into transparent mode and non-transparent mode two kind situation according to network side to the processing of response in the flow process of IMS-MT (message in IMS territory stops) based on the intercommunication of messaging service on the service aspect of SIP.

Under transparent mode, traditional called end user is finally receiving response that short message later on just returns from a 200OK to Calling Side to SMI AS, and idiographic flow is as shown in Figure 7; Under non-transparent mode; SMIAS receive encapsulation that S-CSCF transmits handle successfully based on the message of SIP and mandate and the message format conversion etc. of carrying out interworking service after; Just send the response of a 200OK to Calling Side, here, SMI AS is equivalent to the short message service center of callee side; Follow-up Message Processing flow process is carried out by SMI AS fully, and idiographic flow is as shown in Figure 8.

Fig. 7 is according to the sip message of framework shown in Figure 4 and the traditional short message IMS-MT schematic flow sheet under transparent mode in the intercommunication of business service aspect.

Step 1, according to the IMS register flow path, UE is registered among the S-CSCF, and I-CSCF and P-CSCF in the IMS core do not show in the drawings; And according to the third-party registration flow process, UE is registered on IP message gateway and the SMI AS.

Step 2, traditional short message service center sends route information query request to HSS, and HSS is forwarded to the IP message gateway to route requests, and the IP message gateway returns the address of oneself to short message service center.

Step 3, short message service center is forwarded to the IP message gateway to traditional short message.

Step 4, the IP message gateway sends route information query request to HSS, and HSS returns the address of MSC and/or SGSN.

The selection of network domains according to the strategy of operator and user's preference, is carried out in step 5, IP message gateway address through the own S-CSCF that preserves when the third-party registration and the address of the MSC/SGSN that obtains from HSS.

Step 6, if selection is the IMS territory, the IP message gateway is encapsulated in short message in the message body based on SIP.

Step 7, the message based on SIP of IP message gateway forwards encapsulation arrives S-CSCF.

Step 8; S-CSCF carries out the inspection of the 3rd initial filter criteria to what receive based on the message of SIP; This inspection comprises whether successful being registered on the SMI AS of called end user; And this current called user terminal can not support that traditional short-message protocol stack is a SMS messaging protocol stack, if then will send on the SMI AS based on the message of SIP; Perhaps be checked through user preferences or carrier policy requirement and carry out the information such as intercommunication of service layer, then will send to based on the message of SIP on the SMI AS.

Check result is forwarded on the SMI AS for requiring in this example.If check result is not forwarded on the SMI AS for requiring, then realize issuing by the IMS immediate message of prior art to encapsulation.

Step 9, S-CSCF arrives SMI AS to the forwards based on SIP of encapsulation.

Step 10, SMI AS carries out Authorized operation to interworking service, promptly from the message that receives, obtains the called UE sign; According to this CAMEL-Subscription-Information that identifies said UE registration, carry out the interworking service mandate, if authorize successfully; SMI AS carries out decapsulation to the IMS immediate message; Obtain traditional short message form, SMIAS checks that can the message body of traditional short message convert the form of sip message to, if can; Then carry out by traditional short message to the conversion based on the message format of the message of SIP, whether SMI AS can back up the immediate message of preserving after the conversion according to the policy selection of operator; Otherwise SMI AS returns failure reporting to S-CSCF.

Step 11, the message based on SIP that SMI AS returns after the conversion arrives S-CSCF.

Step 12, S-CSCF transmits the message based on SIP that receives and arrives the called end user.

Step 13, the called end user returns message based on SIP and successfully receives and respond S-CSCF.

Step 14, the successful reception that S-CSCF transmits based on sip message responds SMI AS.

Step 15, SMI AS returns success and responds S-CSCF.

Step 16, S-CSCF returns success and responds the IP message gateway.

Fig. 8 is to the sip message of framework shown in Figure 4 and the traditional short message IMS-MT schematic flow sheet under non-transparent mode in the intercommunication of business service aspect.Step 1-10 and the step 1-10 among Fig. 7 among this figure are identical, repeat no more, and below only begin explanation from step 11.

Step 11, SMI AS sends message and successfully receives response 200OK to S-CSCF.

Step 12, S-CSCF transmits message and successfully receives response 200OK to the IP message gateway.

Step 13, the message based on SIP that SMI AS returns after the conversion arrives S-CSCF.

Step 14, S-CSCF is issued to UE to the message based on SIP through the IMS territory, and wherein I-CSCF and P-CSCF do not show in the drawings.

Step 15, the response that the UE return messages successfully receive is to S-CSCF.

Step 16, the response that the S-CSCF return messages successfully receive is to SMI AS.

In addition, IP message gateway or SMI AS can also be used for the charging bill generating run of interworking service in the MT flow process.

In general, traditional short message service center all requires the called end user to return a message later on based on the message of SIP and send report (Delivery report) successfully receiving.Because the UE in the present embodiment is pure IMS user, be the form of not supporting traditional short message territory, therefore, this Delivery report is initiated by SMI AS in the present embodiment.

Professional and according to above conventional message based on the intercommunication of messaging service on the service aspect of SIP flow process at IMS-MT; Under transparent mode; SMI AS is after finally receiving the response that the 200OK message through S-CSCF transmits that the called end user returns successfully receives; Can generate a Delivery report, and be encapsulated in it in the message body based on SIP and to send; Under non-transparent mode, SMI AS also can generate a Delivery report after the processing of the mandate of the sip message that receives being carried out interworking service and format conversion, and is encapsulated in it in the message body based on SIP and sends.Under these two kinds of patterns, having only time that Delivery report produces difference to some extent, is identical for the handling process of network side, and idiographic flow is as shown in Figure 9.

Shown in Figure 9 for sending the schematic flow sheet of reporting to returning in the process among the IMS-MT of framework shown in Figure 4.

Step 1, the transmission flow of IMS-MT is with reference to Fig. 7 and Fig. 8.

Step 2, SMI AS is according to the transmission situation based on the message of SIP, structure Delivery report, and be encapsulated in it in the sip message body and be sent to S-CSCF.

Step 3, S-CSCF transmits the Delivery report of encapsulation to the IP message gateway.

Step 4, IP message gateway return success response 200OK to S-CSCF.

Step 5, S-CSCF returns success response 200OK to SMI AS.

Step 6, the IP message gateway carries out decapsulation to the Delivery report of encapsulation.

Step 7, the Delivery report after the decapsulation of IP message gateway forwards is to traditional short message service center.

Step 8, short message service center receives after the Delivery report, sends a status report to HSS, upgrades the database among the HSS.

So far, whole M T process finishes.

This execution mode also provides two kinds of message intercommunication entities simultaneously, and it is to be used to realize sip message and traditional short message network entity or the functional module in service layer's intercommunication.Explanation is as follows respectively:

A kind of message intercommunication entity, shown in figure 10, comprising: storage forwarding module, message conversion module and service authorization module.The storage forwarding module can comprise that submodule one is transmitted in storage and submodule two is transmitted in storage; Storage is transmitted submodule one and is responsible for transmitting to the storage of traditional short message based on the message of SIP; Storage is transmitted submodule two and is responsible for the storage forwarding of traditional short message to sip message, and this two sub-module function also can be combined into a general storage forwarding module; Message conversion module can comprise message conversion submodule one and message conversion submodule two; Message conversion submodule one is responsible for the format conversion of sip message to traditional short message; Message conversion submodule two is responsible for the message format conversion of traditional short message to sip message, and this two sub-module function also can be combined into a general message conversion module.Storage forwarding module, message conversion module and these three kinds of modules of service authorization module can be arranged in the various network entity, also can be arranged in the consolidated network entity, as be integrated among the SMI AS.

Storage is transmitted submodule one and can be closed again with message conversion submodule one and be called the sip message adaptation module, main being responsible for based on the message of the SIP interworking service to traditional short message.These two kinds of modules can be arranged in the consolidated network entity, also can be arranged in the various network entity.Storage forwarding submodule two can close again with message conversion submodule two and be called the SMS adaptation module, mainly is responsible for traditional short message and arrives the interworking service based on the message of SIP.These two kinds of modules can be arranged in the consolidated network entity, also can be arranged in the various network entity.The service authorization module is used to receive storage and transmits the request that the service authorization that submodule two sends is transmitted in submodule one or storage; CAMEL-Subscription-Information according to the user carries out service authorization, and returns service authorization and respond that submodule one is transmitted in storage or submodule two is transmitted in storage.

Referring to Figure 11,12 and 13, its be at sip message and traditional short message when the service aspect realizes conversion, storage forwarding module, message conversion module and the various handling process sketch map of service authorization module.

The storage forwarding module comprises that storage transmits submodule one and transmit submodule two with storage, receives the message from network side, should comprise short message from the message of network side and based on the message of SIP, send the service authorization request to the service authorization module; Receive after the authorization response from the service authorization module; If the response of positive; Just forward the message to message conversion module; If the response of negative just returns errored response and handles accordingly to traditional message route entity or to message, as issuing by prior art etc.; The message that reception is returned from message conversion module confirms that this message is sip message or traditional short message, if sip message then issues to the IMS domain network side, if traditional short message then issues to traditional short message domain network side.

The service authorization module is received and after the service authorization request user's CAMEL-Subscription-Information is checked, and responds to storage forwarding module return authorization.

Message conversion module; Comprise message conversion submodule one and message conversion submodule two, after receiving the message that the storage forwarding module sends, this message comprises traditional short message and based on the message of SIP; Carry out the conversion of message format, turn back to the storage forwarding module to conversion back message.

Another kind of message intercommunication entity, shown in figure 14, comprising: storage forwarding module, service authorization module and message conversion module.These three kinds of modules can be arranged in the various network entity, also can be arranged in same network entity.Wherein store forwarding module and link to each other with traditional message route entity, message conversion module links to each other with the IMS territory.

Referring to Figure 15,16 and 17, its be by traditional short message to sip message when the service aspect realizes conversion, storage forwarding module, message conversion module and the various handling process sketch map of service authorization module.

The storage forwarding module after being used for receiving the short message from traditional short message territory conventional message route entity, sends the service authorization request to the service authorization module; Reception is from the authorization response of service authorization module; If this authorization response is the response of positive; Just forwards is arrived message conversion module; If this authorization response is the response of negative, just returns errored response and handle accordingly, as issuing by prior art etc. to traditional message route entity or to message;

The service authorization module is received, is used for after the service authorization request user's CAMEL-Subscription-Information being checked, and to the response of storage forwarding module return authorization;

Message conversion module is used for after the traditional short message that receives the transmission of storage forwarding module, becoming the message format based on SIP to traditional short message conversion, and being forwarded to the IMS territory to the sip message after the conversion.

Referring to Figure 18,19 and 20, its be by sip message to traditional short message when the service aspect realizes conversion, storage forwarding module, message conversion module and the various handling process sketch map of service authorization module.

Message conversion module is used to receive after the message based on SIP from the IMS territory, sends the service authorization request to the service authorization module; Reception, is handled to the IMS territory or to message otherwise return errored response if response just becomes traditional short message format to the message conversion based on SIP for positive from the service authorization response of service authorization module accordingly;

The service authorization module receives after the service authorization request, carries out service authorization according to user's CAMEL-Subscription-Information, and returns the response of service authorization;

The storage forwarding module is used to receive after traditional short message, transmits short message and arrives the short message route entity in traditional short message territory.Have, before transmitting, the storage forwarding module can carry out storage backup to short message according to carrier policy again.

Execution mode two:

The function of integrated information series business router of IP-MESSAGE-GW and SMI AS; Directly realize the selection in territory, the authentication of user's service aspect interworking service and the functions such as conversion of message format by IP-MESSAGE-GW; Like this; Network need not increase under the situation of new entity, only need strengthen the function of IP message gateway, just can realize based on the message of SIP and the traditional short message service intercommunication about the service aspect.

In this scheme, the IP message gateway is through just knowing from the CAMEL-Subscription-Information of HSS download user whether the user has Service level interworking (intercommunication of service aspect) when the third-party registration.In the flow process that IMS message stops, the IP message gateway has received after the short message of traditional route entity forwarding, and to HSS inquiry routing iinformation, HSS only returns the address of MSC and/or SGSN.The address information and the MSC that receive and/or the address of SGSN about IMS territory of IP message gateway through in third-party registration, obtaining carried out the selection in territory according to the strategy of operator and user's preference.If what select is the IMS territory; And know the user Service level interworking that contracted according to CAMEL-Subscription-Information; And current user terminal can not be supported SMS messaging protocol stack, and perhaps user preferences or carrier policy require to carry out the intercommunication of service layer, and then the IP message gateway becomes the form based on the message of SIP to short message conversion; And preserve the message after the conversion based on SIP, then the message based on SIP after the conversion is issued; If the user is signatory Service level interworking, and user terminal support SMS messaging protocol stack, the IP message gateway is encapsulated in short message in the message based on SIP and issues, and its method is consistent with prior art.

Network architecture in this execution mode is shown in figure 21:

In the network architecture shown in Figure 21, comprising: traditional short-message system, IMS core net, user terminal, and IP message gateway, the i.e. function of integrated information series business router of IP-MESSAGE-GW and SMI AS with message format transfer capability.The IP message gateway links to each other with IMS Core network through ISC interface; What use is Session Initiation Protocol; HSS with Sh interface and calling terminal links to each other through the MAP interface, and the MAP interface mainly is used for realizing the function of classes of messages router, and what Sh interface used is the DIAMETER agreement; Be mainly used under the situation of plurality of access modes coexistence, inform that HSS user has the ability that IMS inserts.The IP message gateway links to each other with traditional short message service center through the E/Gd interface.

According to network architecture shown in Figure 21, the user will use the message intercommunication of service aspect professional, must first be registered to the IP message gateway through the third-party registration flow process, its register flow path consistent with prior art promptly with register flow path basically identical shown in Figure 2.Difference only is in the Client-initiated register requirement, to comprise the feature tag whether indication self supports the SMS/EMS ability.

Traditional messaging service and shown in figure 22 in the flow process of IMS-MO (message in IMS territory is initial) based on the intercommunication of messaging service on the service aspect of SIP:

Step 1, according to the IMS register flow path, UE is registered among the S-CSCF, and here, for simplicity, other network entities among the IMS core such as I-CSCF and P-CSCF do not show in the drawings; And according to the third-party registration flow process, UE is registered on the IP message gateway.

Step 2, UE, can carry in this message body and exchange service identification (CSID, Communication service identity) sending among the S-CSCF based on the message of SIP through the IMS territory, is used to identify whether the contracted interworking service of classes of messages of calling UE.

Step 3, S-CSCF carries out the inspection of the 4th initial filter criteria to what receive based on the message of SIP, is sent to the IP message gateway to determine whether the message that needs will be somebody's turn to do based on SIP.This inspection comprises: if carried the CSID sign in the message based on SIP; Then this inspection comprises according to CSID and confirms whether the contracted interworking service of classes of messages of user; If do not carry CSID in the message based on SIP, then this inspection comprises that CSI called subscriber identification is information such as TEL-URI.The main purpose of this initial filter criteria inspection is to determine whether and need the message that receive be routed to the IP message gateway.

The interworking service or the CSI called subscriber identification of classes of messages are TEL-URI if definite user has contracted, and then execution in step 4, otherwise carry out by prior art.

Step 4, S-CSCF arrives the IP message gateway to the forwards based on SIP.

Step 5, the IP message gateway is changed inspection, and this inspection comprises:

Inspection called subscriber's sign, if the called subscriber is the form (in caller is IMS user, and called is under the PS/CS user situation) of TEL-URI, the IP message gateway carries out the ENUM inquiry to the called subscriber.

If the ENUM successful inquiring, promptly TEL-URI can successful conversion become under the SIP-URI situation, and the IP message gateway is the IMS territory that sends to the called end user based on the message of SIP, and transmission flow is consistent with existing send mode; If ENUM inquires about failure, the sip message that the inspection of IP message gateway receives.

If this sip message is an encapsulation format, the IP message gateway carries out decapsulation to sip message, obtains traditional short message format; If this sip message is not the form of encapsulation, perhaps user preferences or carrier policy require to carry out the intercommunication of service layer, and then the IP message gateway is authorized interworking service, promptly check whether the contracted interworking service of service aspect of calling terminal UE.

If authorization check is success not, show that then this moment, the IP message gateway returned failure response to Calling Side not through the conversion inspection.

If authorization check success, then the IP message gateway reexamines message body and whether can carry out format conversion:

If can not carry out format conversion, show that then this moment, the IP message gateway returned failure response to Calling Side not through the conversion inspection.

If can carry out format conversion; Then show and passed through the conversion inspection, this moment, the IP message gateway reexamined the address that whether can obtain called end user tradition short-message system address such as the SM-SC of short message service center, if can not; Then show not through the conversion inspection, return failure response to Calling Side.

If can obtain; Then the IP message gateway converts sip message into short message format; This conversion comprises the conversion of message body and the conversion of ID; Comprise like the conversion of ID the calling and called ID is converted into form that traditional short-message system can discern as SIP-URI being converted to the TEL-URI form; Also can message be split and assemble, as having the short message of serial number to transmit, or transmit etc. dress up an EMS message format based on the message groups of SIP splitting into multi-ribbon based on the message of SIP according to the strategy of operator; The IP message gateway is transmitted the message after changing.Wherein, the IP message gateway obtains the process of called end user tradition short-message system address and is:

When the IP message gateway integrated during traditional short message service center function, the IP message gateway directly obtains the address of MSC/SGSN to the HSS request route information, and based on the strategy of operator and user's preference, selects suitable route that short message is transmitted; When the not integrated traditional short message service center of IP message gateway function; The IP message gateway is dealt into traditional short message service center to the short message after changing; Obtain the address of MSC/SGSN to the HSS request route information by short message service center; And, select suitable route that short message is transmitted based on the strategy of operator and user's preference.

If authorization failure, then the IP message gateway returns failure reporting to calling UE, and it is consistent with existing processing mode.

Step 6-7; The response message based on sip message after the IP message gateway will be changed sends to UE through the IMS network; The response here can directly be returned later in the processing of IP message gateway completion interworking service, also can return Delivery report IP message gateway waits called end user and return later on.

Have, the step 3 among above-mentioned Figure 22～5 also have a kind of possible implementation to be again:

Step 3 '; S-CSCF carries out the inspection of the 4th initial filter criteria to what receive based on the message of SIP; This inspection comprises: the feature tag that this sip message carries is "+g.oma.sip-im " or "+g.3gpp.smsip "; Or whether the contracted interworking service of service aspect of inspection calling subscriber, or whether the message identification of the CSID that carries of inspection sip message is that the intercommunication class of service aspect is professional.

If feature tag is "+g.3gpp.smsip ", then carry out, if feature tag is its excess-three kind situation then execution in step 4 by prior art.

Step 4 ', S-CSCF arrives the IP message gateway to the forwards based on SIP.

Step 5 '; The IP message gateway is changed inspection; If through the conversion inspection; The message conversion based on SIP that then will receive is traditional short message format, converts the calling UE sign into form that traditional short-message system can be discerned, and the traditional short message after will changing afterwards is sent to traditional short-message system.

Above-mentioned conversion inspection comprises:

The IP message gateway judges whether that according to calling subscriber's preference and carrier policy needs serve the intercommunication of aspect, and have three kinds of possible situation this moment: need the service aspect intercommunication, handle, need not serve the aspect intercommunication by default situations.

The intercommunication of capable service aspect if desired; Caller network IP message gateway is authorized interworking service, if authorize successfully, then confirms through the conversion inspection; At this moment; The IP message gateway of caller network becomes short message format to the message conversion based on SIP, is forwarded to traditional short-message system to the message of format transformation, accomplishes follow-up repeating process by traditional short-message system;

Handle by default situations if desired; IP message gateway inspection called subscriber's sign; (in caller is IMS user if the called subscriber is for the form of TEL-URI; Called is under the PS/CS user situation), the IP message gateway is to carry out issuing of message through IMS territory or CS/PS territory according to the number segment information or the selection of ENUM Query Result of self-configuring.

If the called territory of selecting is the IMS territory, the IP message gateway is the network entity S-CSCF that sends to called end user's IMS domain core net network based on the message of SIP, and transmission flow is consistent with the send mode of prior art IMS immediate message.If the called territory of selecting is the CS/PS territory, the sip message that the inspection of IP message gateway receives, if this sip message is an encapsulation format, the IP message gateway carries out decapsulation to sip message, obtains traditional short message format; If this sip message is not the form of encapsulation; IP message is authorized interworking service; Promptly check whether the contracted interworking service of service aspect of calling terminal UE; If the authorization check success, the IP message gateway converts sip message into short message format, and this conversion comprises the conversion of message body and the conversion of ID; Comprise like the conversion of ID calling subscriber identification is changed (converting SIP-URI to the TEL-URI form); Also can message be split and assemble (as having the short message of serial number to transmit splitting into multi-ribbon based on the message of SIP, or transmit etc. dress up an EMS message format based on the message groups of SIP) according to the strategy of operator, authorization failure then IP message gateway returns failure reporting.The IP message gateway is transmitted the message after changing.That is to say that the IP message gateway is selected the called territory network that sip message issues according to called subscriber's sign, when selecting the CS/PS territory to issue, after said IP message gateway is to interworking service mandate success, confirm through the conversion inspection.

If need not serve the aspect intercommunication; What the IP message gateway was selected according to the result of the number segment information of self-configuring or ENUM inquiry is the IMS territory; Forward the message to the called IMS network by prior art,, then return the S-CSCF of failure reporting to the caller network if SMI AS can not select the IMS territory.That is to say that if need not serve the aspect intercommunication, then SMI AS can not select the CS/PS territory, can only option IMS territory issuing message, select in the IMS territory to confirm to return failure reporting when unsuccessful through the conversion inspection.

Be appreciated that the process that above-mentioned steps 5 ' middle IP message gateway is changed inspection comprises: the IP message gateway judges whether the intercommunication of the aspect of need serving.This foundation that judges whether the intercommunication of the aspect of need serving comprises: determine whether that according to calling subscriber's preference or carrier policy needs serve the intercommunication of aspect; Perhaps, when said IP message gateway confirms that the called IMS territory is unreachable, confirm the intercommunication of the aspect of will serving.

Before the message conversion based on SIP that the IP message gateway will receive is traditional short message format; Can further include: the IP message gateway is authorized interworking service; After authorizing successfully, the message conversion based on SIP that will receive again is traditional short message format.

In addition, the IP message gateway can also be used for the charging bill generating run of interworking service.

According to the initial flow process of IMS domain message shown in Figure 21, referring to Figure 23, the IP message gateway of integrated SMI AS function should have following function:

1. during third-party registration through Sh interface download user subscription data

2. the obtaining of called end user short message service center SM-SC address (the SM-SC address can be configured in the IP message gateway, and perhaps the IP message gateway just is equivalent to the sms center of called end)

3. the mandate of customer service

4. the conversion of calling identification (SIP-URI converts the TEL-URI form to)

5. the conversion of message (encapsulation or format conversion)

6. the fractionation of message and assembling, this function is optional as required

7. the charging of interworking service (generating user's ticket (CDR))

8. judge whether that according to user preference and carrier policy needs serve the interworking service of aspect

9. called end message is sent the selection in territory

Figure 24 is to the sip message of framework shown in Figure 21 and the traditional short message IMS-MT schematic flow sheet in the intercommunication of business service aspect.

Step 1, according to the IMS register flow path, UE is registered among the S-CSCF, and I-CSCF and P-CSCF among the IMS core do not show in the drawings; And according to the third-party registration flow process, UE is registered on the IP message gateway.

Step 4, the IP message gateway sends route information query request to HSS, and HSS returns the address of MSC and/or SGSN.The IP message gateway here can be equivalent to short message service center's function of a called end, like SM-Router (with reference to TS23.840), can handle accordingly the message that receives, and like rubbish filtering, looks into poison etc.

The selection in territory according to the strategy of operator and user's preference, is carried out in step 5, IP message gateway address through the own S-CSCF that preserves when the third-party registration and the address of the MSC/SGSN that obtains from HSS.

Step 6; If what select is the IMS territory; The user's that the inspection of IP message gateway obtains in the third-party registration process CAMEL-Subscription-Information; Whether support Service level interworking like the user, whether support SMS messaging protocol stack etc., the user's of this acquisition CAMEL-Subscription-Information promptly is used for authorization check.

If the user supports Service level interworking; And current user terminal can not be supported SMS messaging protocol stack; Perhaps user preferences or carrier policy require to carry out the intercommunication of service layer; Whether the form that then reexamines message body can carry out format conversion, if can, be traditional short message conversion form then based on the message of SIP; Whether the conversion of carrying out the calling and called sign is about to the calling and called sign and converts the form that the IMS network can be discerned into, and can select the message after the conversion to be stored according to the preference of operator;

If the user does not support Service level interworking; And user terminal is supported SMS messaging protocol stack and is registered to the IP message gateway; Perhaps; The form of message body can not carry out format conversion, and then the IP message gateway is traditional short message conversion to be encapsulated in based on the mode that promptly encapsulates according to existing transport layer in the message body of SIP to encapsulate conversion, carries out subsequent treatment by prior art afterwards.

The IP message gateway can also split and assemble message according to the strategy of operator; As splitting into many short messages to long message (like EMS); And be assembled into the message based on SIP to the short message after splitting and issue, perhaps be assembled into a message to the short message of a plurality of associations and transmit based on SIP.

The IP message gateway is preserved the processing mode of encapsulation format interworking service after the processing of accomplishing the message interworking service, this preservation promptly can be under the encapsulation format also can be transition form after.

Step 7, the IP message gateway arrives S-CSCF to the forwards based on SIP, and this sip message possibly be the form after the conversion, also possibly be the form after the encapsulation.

Step 8, the inspection that S-CSCF carries out initial filter criteria to the message based on SIP that receives is aforesaid first initial filter criteria inspection.

Step 9, S-CSCF is forwarded to UE to sip message through the IMS territory.

Step 10, the response that the UE return messages successfully receive is to S-CSCF.

Step 11, the response that S-CSCF forwarding message successfully receives is to the IP message gateway.

According to the flow process that above-mentioned IMS domain message stops, referring to Figure 25, the IP message gateway of integrated SMI AS function has following ability:

The feature tag of the terminal capability that 1. the storage user terminal carries when third-party registration

2. during third-party registration through the subscription data of Sh interface download user, be used for service authorization to the user

3. to the conversion of calling and called ID, convert the TEL-URI of calling and called identifier to the form (can inquire about) of SIP-URI through ENUM

4. the conversion of message format

5. the assembling of message format

6. carry out the function of traditional sms center, like rubbish filtering, virus killing etc.

7. to interworking service charge (generate CDR)

In Figure 25, be whether the terminal supports that the inspection of SMS is optional to the inspection of terminal capability.

In the flow process that the described IMS domain message of Figure 24 stops; The professional processing mode of the message intercommunication that the IP message gateway is preserved is under the situation of encapsulation; When being user terminal support SMS messaging protocol stack; What IP message gateway waits user terminal sent is encapsulated in based on the Delivery report in the message body of sip message, and it is carried out decapsulation is forwarded to traditional sms center, and its handling process is consistent with prior art; The professional processing mode of message intercommunication of preserving at the IP message gateway is under the situation of format conversion; What be that the user uses is the interworking service of service level; The IP message gateway is after receiving that message that S-CSCF returns successfully receives response; According to Delivery report of response structure, directly send to the short message service center of Calling Side, this moment is shown in figure 26:

Step 1, the IMS-MT transmission flow is with reference to Figure 24.

Step 2, a Delivery report is constructed in the response that the IP message gateway sends according to the message of receiving from S-CSCF, and sends to short message service center to Delivery report.

Step 3, short message service center's status report are upgraded the HSS database to HSS.

Based on the system framework and the flow process of sip message and the traditional short message intercommunication of Figure 21-26, this execution mode is same to exist two kinds of message intercommunication entities.Content shown in Figure 10-20 is identical in itself and the execution mode one, repeats no more.

Execution mode three:

SMI AS directly links to each other through the MAP interface with the IP message gateway.The IP message gateway can obtain the address information of SMI AS through the MAP of expansion to HSS; Also can be through the internal logic of HSS; The priority of returning the address of SMI AS is made as the highest, and like this, the IP message gateway need not pass through S-CSCF just can directly send to SMI AS to the message based on SIP after the encapsulation;, again message is stored and transmitted after carrying out the conversion of decapsulation and message format based on the message of SIP by SMI AS.

In this implementation, when needing the user to support Service level interworking equally, just can carry out third-party registration to SMI AS; In the third-party registration process; SMI AS is kept at the address of oneself among the HSS, and its register flow path is consistent with first kind of execution mode, so; When the user had only the Servicelevelinterworking of support, S-CSCF could be forwarded to SMI AS to message through initial filter criteria.

Figure 27 is the configuration diagram according to sip message and traditional short message intercommunication of the embodiment of the invention three.It comprises traditional short-message system, IMS core net, IP message gateway, user terminal, and the newly-installed message intercommunication entity SMI AS that is used to carry out the message format conversion of the present invention.

In Figure 27, SMI AS can be a network entity that increases newly, also can be the newly-increased functional module on the existing network entity.It links to each other with IMS Core network through the ISC interface of 3GPP definition, and selected agreement is a Session Initiation Protocol.When the function of the integrated traditional short message service center of SMI AS; The tradition short-message system comprises the HSS that is positioned at called network; And MSC and/or SGSN, and SMI AS can link to each other with the HSS of called end network through C interface, links to each other with the MSC/SGSN of called end network through E/Gd; When SMI AS did not have the function of traditional short message service center, traditional short-message system comprised traditional short message service center, and this moment, SMI AS linked to each other with traditional short message service center through the E/Gd interface.Directly link to each other through the MAP interface between SMI AS and the IP message gateway.The difference of itself and network frame shown in Figure 4 is: be the MAP interface between SMI AS and the IP message gateway in the present embodiment, and be the E/Gd interface between SMI AS and the IP message gateway in the network architecture shown in Figure 4.

According to network architecture shown in Figure 27; Third-party registration flow process to the IP message gateway is consistent with first kind of embodiment; The tradition short message service is also consistent with first kind of embodiment in the flow process of IMS-MO (message in IMS territory is initial) with the intercommunication on the sip message business service aspect, no longer does description here.

Intercommunication on tradition short message service and the sip message business service aspect is shown in figure 28 in the flow process of IMS-MT; Here; For simplicity; This flow process is an example with the transparent mode only for the processing of response, and is also consistent with the processing in the execution mode one about the processing of non-transparent mode, repeats no more.Referring to Figure 28:

Figure 28 is sip message and the traditional short message IMS-MT schematic flow sheet under the transparent mode of business service aspect intercommunication to framework shown in Figure 27.

Step 1, according to the IMS register flow path, UE is registered among the S-CSCF, and according to the third-party registration flow process, UE is registered on IP message gateway and the SMI AS.

Step 2, traditional short message service center sends route information query request to HSS, and HSS is forwarded to the IP message gateway to route requests, and the IP message gateway returns the address of oneself to sms center.

Step 3, sms center is forwarded to the IP message gateway to traditional short message.

Step 4, the IP message gateway sends route information query request to HSS, and HSS can return the address of MSC and/or SGSN and the address of SMI AS through the MAP of expansion; HSS also can be through self internal logic, and the priority of returning SMI AS address is made as the highest, returns the address of SMI AS address and MSC or SGSN through the MAP address.

Step 5, the IP message gateway according to the strategy of operator and user's preference, carries out the selection in territory from the address of the MSC/SGSN of HSS acquisition and the address information of SMI AS.

Step 6; If selected territory is the IMS territory; The IP message gateway is carried out inspection, and to determine whether being sent to SMI AS with receiving message, this inspection comprises the called subscriber's that inspection obtains CAMEL-Subscription-Information in the third-party registration process; If the called subscriber supports Service level interworking; And current user terminal can not be supported SMS messaging protocol stack, and perhaps user preferences or carrier policy require to carry out the intercommunication of service layer, and the IP message gateway is directly transmitted short message to SMI AS through the MAP interface; Otherwise the IP message gateway issues the message based on SIP that encapsulates by the address of prior art according to the S-CSCF in the IMS territory of in third-party registration, preserving.

Step 7, SMI AS carries out the interworking service mandate, promptly from the message that receives, obtains the called UE sign; According to this CAMEL-Subscription-Information that identifies said UE registration, carry out the interworking service mandate, if authorize successfully; Can the message body that SMI AS reexamines received short message convert the form of sip message to; If can, SMI AS carries out by the format conversion of traditional short message to sip message, preserves the message based on SIP after changing; If authorization failure, SMI AS returns failure reporting to S-CSCF.

Step 8, the message based on SIP that SMI AS returns after the conversion arrives S-CSCF.

Step 9, S-CSCF is issued to called end UE to the message based on SIP through the IMS territory.

Step 10, the called end user returns message based on SIP and successfully receives and respond S-CSCF.

Step 11, S-CSCF transmits message based on SIP and successfully receives and respond SMI AS.

Here; SMI AS is after receiving the response that the message transmitted by S-CSCF successfully receives; Generate a Delivery report according to response; Directly send to the IP message gateway to Delivery report through the MAP interface, be forwarded to short message service center to Delivery report, send a status report by short message service center again and carry out corresponding Data Update to HSS by the IP message gateway.

Among Figure 27-28 based on the message of SIP and traditional short messaging service in the flow process of the intercommunication on the service aspect at IMS-MT; Comprise transparent mode and non-transparent mode; After having only the user successfully to be registered on the SMIAS, S-CSCF just possibly be routed to SMIAS to the message based on SIP through initial filter criteria.

In addition, based on the system framework and the flow process of above-mentioned sip message and traditional short message intercommunication, two kinds of message intercommunication entities of the same existence of this execution mode.Content shown in Figure 10-20 is identical in itself and the execution mode one, repeats no more.

Execution mode four:

SMI AS can directly link to each other with traditional short message route entity through the MAP interface, also can link to each other with traditional short message route entity through middle router.Traditional short message route entity can obtain the address information of SMI AS through the MAP of expansion to HSS; Also can be through the internal logic of HSS; The priority of returning the address of SMI AS is made as the highest, returns the address of SMI AS and the address of MSC or SGSN through MAP.Traditional short message route entity is carried out the selection in territory according to carrier policy and user's preference.If what select is the IMS territory, traditional short message route entity directly is routed to short message on the SMI AS.Technical scheme in realization of this execution mode and the execution mode three is closely similar, and unique difference is exactly that SMI AS receives short message from legacy network through the IP message gateway, and directly receives through traditional short message service center.

Figure 29 is the configuration diagram according to sip message and traditional short message intercommunication of the embodiment of the invention four.It comprises traditional short-message system, IMS core net, user terminal, and the message intercommunication entity SMI AS with message format transfer capability.

Referring to Figure 29, SMI AS can be a network entity that increases newly, also can be the newly-increased functional module on the existing network entity.It links to each other with IMS Core network through the ISC interface of 3GPP definition, and selected agreement is a Session Initiation Protocol.

Under the situation of SMI AS IMS territory, place as domain; When the function of the integrated traditional short message service center of SMI AS; The tradition short-message system comprises the HSS that is positioned at called network; And MSC and/or SGSN, and SMI AS links to each other with the HSS of called end network through C interface, links to each other with the MSC/SGSN of called end network through E/Gd; When the function of the not integrated traditional short message service center of SMI AS, traditional short-message system comprises the traditional short message service center in the caller net, and said SMI AS links to each other with traditional short message service center in the caller net through the E/Gd interface.

Under the situation of IMS territory, SMI AS place as the termination territory, SMI AS directly links to each other through the route entity of the traditional short message in MAP interface and the called network, also can be that he links to each other with traditional short message route entity through the router of a centre.The route entity of above-mentioned traditional short message comprises GMSC and/or SMS-IWMSC.

The above is merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention.All any modifications of within spirit of the present invention and principle, being done, be equal to replacement, improvement etc., all be included in protection scope of the present invention.
