In order to make the sip user accessing mobile communication network, the typical handling process that need finish comprises: the sip user registration and the processing of authentication, the processing and the called processing of sip user of sip user caller.In conjunction with the introduction of these typical handling processes in the preferred embodiment of the present invention the present invention program is described respectively below.
During according to the sip user accessing mobile communication network of a preferred embodiment of the present invention when sip user registration and authentication process the message between each entity transmit schematic diagram as shown in Figure 1.
In the flow process of sip user registration and authentication process, the entity that relates to comprises: for the sip terminal 10 that sip user uses, comprise the MSC20-1 of SIP module 21, MAP module 22 and VLR24-1, HLR30-1.Wherein, HLR30-1 is the attaching position register (Home Location Register is called for short " HLR ") of the registered address MSC of sip terminal 10; The VLR of place MSC20-1 when VLR24-1 is sip terminal 10 registrations.
In this process, being registered in of sip terminal 10 will be converted to MAP and finish registration process on the MSC20-1, and this process is the process upgraded of position, simulating mobile terminal start back basically.
At first, sip terminal 10 sends SIP registration message (SIP:REGISTER) to SIP module 21.Wherein, comprise user's international mobile station identity number (International MobileStation Identify is called for short " IMSI ") in the SIP registration message, IMSI is by reading in the SIM card of sip terminal 10 from the SIM card card reader.
Then, after SIP module 21 is received registration message, analyze and find to have IMSI in the SIP registration message, then send and upgrade location message (UPDATE_LOC) to MAP module 22.Wherein, in the UPDATE_LOC message user's IMSI and sip user sign passed to MAP module 22.
Then, MAP module 22 sends standard MAP to VLR24-1 and upgrades position area message (MAP_UPDATELOCATION_AREA), and the position of initiation standard is new technological process more.In this step, MAP_UPDATELOCATION_AREA message sends user's MSISDN and user profile and sip user sign and be inserted in the location register.
Then, enter the related procedure of authentication.Wherein, the related procedure of authentication is equally also shone upon by sip message and MAP and is finished.
In the time of authentication, send MAP authentication message (MAP_AUTHENTICATE) by VLR24-1 to MAP module 22 earlier.Wherein, MAP_AUTHENTICATE has comprised the authentication vector that is generated by VLR24-1.
Then, send authentication request message (authentication req) to SIP module 21 behind the MAP module 22 storage authentication vectors.
After SIP module 21 was received authentication req message, to the authentication message (401 Unanthenticated) of sip terminal 10 transmission SIP standards, expression needed sip terminal 10 to generate authentication collection information to carry out authentication.
Then, generate the authentication collection and send to SIP module 21 according to the information in the SIM card by sip terminal 10 by sip message (SIP:REGISTER).Wherein, this sip message is placed on newly-increased " Authorization: " territory with the information encryption of authentication collection.
Then, SIP module 21 solves the authentication collection, sends to MAP module 22 and carry out authentication in authentication response message (authentication rsp).
After authentication was errorless, MAP module 22 sent authentication responses message (MAP_AUTHENTICATE_ack) and gives VLR24-1.
So far, finish the process of authentication, proceed the operation that the position is upgraded.
Below, send standard MAP by VLR24-1 to HLR30-1 and upgrade location message (MAP_UPDATE_LOCATION), HLR30-1 receives back answer MAP_INSERT_SUBSCR_DATA message, VLR24-1 then sends response message (MAP_INSERT_SUBSCR_DATA_ack) to HLR30-1, HLR30-1 receives that back transmission standard MAP upgrades position response message (MAP_UPDATE_LOCATION_ack) expression position and upgrades success, has upgraded the positional information of current sip terminal 10 in HLR30-1.
Then, each module is upgraded successful message feedback to sip terminal 10 with the position successively.In this step, VLR24-1 sends and upgrades band of position response message (MAP_UPDATELOCATION_AREA_ack) to MAP module 22, send after MAP module 22 is received and upgrade success message (UPDATE_ACK), send standard SIP after the SIP module 21 recording user log-on datas and succeed in registration message (200OK) to sip terminal 10 to SIP module 21.
The registration when so far, finishing the sip user accessing mobile communication network and the processing of authentication.
In the time of the sip user caller, two kinds of situations are arranged:
1. use and aim at the number of the account initiation caller that sip user distributes.Under this situation, whole business that the user can use present SIP to provide, too many not related with mobile communications network, be not described in detail at this.
2. the MSISDN that uses mobile communications network to distribute initiates caller.Under this situation, similar mobile subscriber's calling procedure, but can only realize the business that present walking circuit territory is supported, SIP is not provided newly-increased business.
Need to prove, adopt which type of mode to initiate caller and can independently select, select different called numbers to realize by call initiator by sip user.
The schematic diagram that message was transmitted between the entity when sip user was called out the mobile subscriber during according to the sip user accessing mobile communication network of a preferred embodiment of the present invention as shown in Figure 2.
Call out in mobile subscriber's the handling process at sip user, the entity that relates to comprises: the sip terminal 10 that the caller sip user uses comprises MSC20-1, HLR30-2 and the VLR24-2 of SIP module 21, MAP module 22 and ISUP module 23.Wherein, HLR30-2 is callee's HLR; VLR24-2 is the VLR of the present position of callee.
At first, sip terminal 10 sends invited calls message (SIP:INVITE).Wherein, SIP:INVITE is the standard sip message, is used for inviting the user to add calling.
Then, callee's information in the HLR30-2 inquiry register, Visited Location Registor VLR24-2 to the callee sends MAP_PROVIDE_ROAMING_NUMBER message, and VLR24-2 receives back response MAP_PROVIDE_ROAMING_NUMBER_ack message.Those of ordinary skill in the art are appreciated that like this VLR24-2 just sends to HLR30-2 for the call setup route with callee's detail location information.
Then, HLR30-2 sends routing iinformation request-reply message (MAP_SEND_ROUTING_INF_ack (MSRN)) to MAP module 22, and MAP module 22 sends routing iinformation message (MP_route_info) to SIP module 21 after receiving this response message.Those of ordinary skill in the art are appreciated that like this SIP module 21 has just obtained callee's routing iinformation, can set up calling.
Then send SIP:INVITE message by SIP module 21 to ISUP module 23, ISUP module 23 receives that the back sends ISUP:IAM message call callee to callee's Visited Location Registor VLR24-2.
So far, finish the handling process that sip terminal is called out the mobile subscriber.
When sip user is called, two kinds of situations are arranged:
Use the proprietary number of the account of sip user as called.Under this situation, the whole business that can use present SIP to provide, flow process adopts the SIP flow process.
When using MSISDN to come calling SIP user.Under this situation, flow process adopts with portable terminal called similar.Because the IMSI that is to use of sip user registers in HLR, so other entity of network it seems that this user is common mobile subscriber, do not need to make any modification on flow process and message.Only need doing in MSC inside, mapping gets final product.
