Abstract
The method includes following steps: charging rule for IMS signaling bearer is configured at GGSN; GPRS connection is built on terminal, and a PDP context enabling message is sent to network side; in returned PDR context reception message the network side doesn't indicate IMS signaling for PCO parameter; GGSN records the IP address of P-SCSF corresponding to the terminal, and filters the packet in PDP context in the terminal, and then charges for data sent to or received from P_SCSF base on charging rule for IMS signaling bearer. When terminal makes IMS signaling and non IMS signaling pass through one PDP context, it can implement independent charging for IMS signaling.
Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to the billing technology field of IP multimedia subsystem, IMS.
Background technology
Development along with mobile communication technology, people no longer are satisfied with single voice communication mode, and multimedia communication mode that need be brand-new, this multimedia communication is not only simple video and audio communication, also comprise instant message, with the business that browses the location, collaborative work, Streaming Media or the like business, particularly new traffic mode and traditional voice merge.Trend based on Internet and communication network fusion, third generation partner program (The 3rd Generation Partnership Project, 3GPP) on the basis of packet carrying network, introduced IP Multimedia System (the IP Multimedia Subsystem of all-IP business network framework, IMS), the target of IMS is according to personalized user data, the shielding user mode access, the degree of opening of control professional ability provides multimedia communication experiences.
Topmost functional entity is call session control function module (Call Session ControlFunction among the IMS, CSCF), CSCF has three types: serving CSCF (Serving-CSCF, S-CSCF), proxy CSCF (Proxy-CSCF, P-CSCF), the inquiry CSCF (Interrogating-CSCF, I-CSCF).P-CSCF is IMS terminal first contact point at the IMS network, finishes agent functionality, carries out the IMS Signalling exchange with terminal, carries out inter-process and then it is transmitted to I-CSCF or S-CSCF.I-CSCF considers the network security aspect, finishes network concealed function, and I-CSCF inquired about and determines the S-CSCF that the user serves to HSS when the user registered.The call state of S-CSCF recording user is finished CCF, is topmost operation controlling entity.Different S-CSCF can finish different business functions owing to connect different application servers.
How extensive gradually along with the IMS service application charges reasonably and accurately to the IMS business, has become the problem of mobile operator common concern.Charging at the IMS business has two levels: GPRS (General Packet Radio Service, GPRS) charging in the charging of packet carrying network and IMS territory, the former is by GPRS entity GPRS Support Node (GPRS Support Node, GSN) finish, comprise Gateway GPRS Support Node (Gateway GPRS Support Node, GGSN) and Serving GPRS Support Node (Serving GPRS Support Node, SGSN), the latter is finished by IMS entity CSCF (and application server).The GPRS net can charge at grouped data flow, duration, QoS etc.; Can charge at duration, QoS, business information etc. in the IMS territory.
The IMS territory is based on the professional control domain on the GPRS packet carrying network.The IMS business is made up of control section and media content portion, and control section is the IMS Signalling exchange between IMS terminal and the IM territory entity, and the IMS business is controlled, and media content portion i.e. various content media streams such as image, voice, data, sound.IMS signaling and Media Stream all pass through the carrying of GPRS Packet Based Network, and Media Stream does not need the territory through IMS.To the GPRS packet network, present most operators adopt the mode of charge on traffic, and gprs service node GSN adds up and produce Original CDR to the user's data flow.For the IMS signaling of control IMS business, then generally do not charge, may be successful or unsuccessful because professional, it is irrational when business is unsuccessful the user being charged, so IMS is professional similar with circuit domain business, and signaling is not generally chargeed, and only Media Stream is chargeed.Professional as some IMS by the IMS signaling bear, rather than separately during media stream bearing,, then need to charge by IMS entity CSCF as IMS message, generally adopt event charging, but not the mode of charge on traffic.For the Media Stream in the IMS business, its charging is finished jointly by GPRS entity GSN and IMS entity CSCF, GSN carries charging to Media Stream, be packet data protocol content (PacketData Protocol context, PDP Context) charging, charge informations such as output flow, QoS, duration, CSCF are exported charge informations such as QoS, duration, incident then according to the IMS signaling.
The current GPRS network when carrying is chargeed at packet data streams, can only recognize this minimum particle size of PDPContext, promptly can only export the charge information of certain PDP Context, can not charge to different business stream among the PDPContext (or IP stream).But in reality, because terminal is not supported parallel a plurality of PDP Context, perhaps the network load that brings for the parallel a plurality of PDP Context of minimizing increases the weight of and the complexity increase, a plurality of Business Streams of certain terminal (or IP stream) will use same PDP Context carrying, and different business stream (or IP stream) may need to adopt different charging ways, and the current GPRS network can't satisfy this demand.Specifically correspond to the IMS business, because the carrying of IMS signaling and Media Stream will be adopted different charging ways, as the IMS signaling bear is free of charge, media stream bearing is carried out charge on traffic, but IMS signaling and Media Stream are carried on the PDP Context probably, so can't realize this demand.
In view of the charge mode of current GPRS network, for satisfying the different charge mode is adopted in the carrying of IMS signaling and Media Stream, standard provides a kind of means at present, guarantees that the IMS signaling is by independent PDP Context carrying.When terminal activates a PDP Context, protocol configuration is selected (Protocol Configuration Option in the activation message that network sends, PCO) parameter indicates this PDP Context to be used to carry the IMS signaling, network returns PDP Context to terminal and accepts message, PCO parameter indication IMS signaling in the message, this PDP Context the IMS signaling can only be used to carry with regard to limiting terminal like this, the IMS Media Stream can not be carried; If network returns PDP Context to terminal and accepts the PCO parameter not to be indicated the IMS signaling in the message, then this PDP Context carrying IMS signaling and other Media Stream are not limited.
Current can only be by with IMS signaling and Media Stream mode by different PDP Context carryings, could be to the different charging way of carrying employing of IMS signaling and Media Stream.But because for most IMS business, all there are IMS signaling and Media Stream, need two or more PDP Context carryings, promptly the IMS signaling needs independent bearing on a PDP Context, and Media Stream can be carried on one or more PDP Context.Need terminal can support parallel a plurality of PDP Context like this, and the emphasis network burden.
Summary of the invention
The objective of the invention is to propose a kind of charging method of IP multimedia subsystem, IMS signaling bear, can carry out independent charging to the IP multimedia subsystem, IMS signaling bear, do not use independently PDPContext carrying and do not need to limit the IMS signaling, promptly IMS signaling and Media Stream or other Business Stream are carried on the same PDP Context.

Description of drawings
Fig. 1 is the charging flow figure of IMS signaling bear of the present invention.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described.
This programme provides a kind of implementation to IMS signaling bear independent counting, unlike the prior art be, do not need to limit the IMS signaling and use independently PDP Context carrying, promptly IMS signaling and Media Stream or other Business Stream are carried on the same PDP Context.
Carrying is chargeed and can be realized at GPRS entity SGSN and GGSN, this programme carries independent counting to the IMS signaling of non-independent PDPContext carrying, can only realize at GGSN, because have only GGSN can obtain the information such as purpose IP address, port numbers of each data flow, can not get these information at SGSN.
Consider that this programme prerequisite is that the IMS signaling is not used independent PDP Context carrying, when terminal activates a PDP Context, if the PCO parameter indicates this PDP Context to be used to carry the IMS signaling in the activation message that network sends, then network returns PDP Context to terminal and accepts in the message to PCO parameter indication IMS signaling, its objective is the notice terminal, this PDP Context carrying IMS signaling and other Media Stream are not limited; If terminal does not indicate this PDP Context to be used to carry the IMS signaling to the PCO parameter in the activation message that network sends, represent that then this PDP Context is not used to carry the IMS signaling separately, network returns PDP Context to terminal and accepts in the message also not to PCO parameter indication IMS signaling by normal process.
IMS Signalling exchange between terminal and the IMS network all at first arrives the P-CSCF entity in IMS territory.From GGSN, the IMS signaling that terminal sends or receives all arrives or from P-CSCF, and can not be other entity; And at certain IMS business of terminal, P-CSCF is maintained fixed constant.Address by GGSN record P-CSCF just can distinguish the IMS signaling among the PDP Context.
When terminal is initiated the IMS business, at first need to obtain the IP address of P-CSCF, just can carry out the IMS Signalling exchange.Dual mode is arranged at present: (1) sets up the IP address that obtains P-CSCF when GPRS connects, and promptly terminal sends PDP Conext to network and activates request P-CSCF address in the message, and GGSN returns the IP address of P-CSCF in response message; (2) set up GPRS and connect the IP address that obtains P-CSCF afterwards, mode by DHCP, terminal is to the domain name of Dynamic Host Configuration Protocol server request P-CSCF and the IP address of dns server, terminal therefrom selects one to carry out the IMS Signalling exchange by inquiring about the IP address that dns server obtains a plurality of P-CSCF then.Mode two needs to have between terminal and Dynamic Host Configuration Protocol server, the dns server reciprocal process of a plurality of requests and response, at the charging of these mutual signalings, should take the charging way identical with the IMS signaling; This moment, GGSN was as DHCP relay, can obtain the IP address of Dynamic Host Configuration Protocol server and dns server.
When GGSN carries out independent counting to the IMS signaling bear, must write down the IP address of P-CSCF,, then also need to write down the IP address of Dynamic Host Configuration Protocol server and dns server if use DHCP to obtain the P-CSCF address.In GGSN, static configuration is to the special charging regulation of IMS signaling bear, for example: (1) IMS signaling bear is free, do not add up its flow process, so that only add up the data traffic of non-IMS signaling among the PDP Context, only to the data of non-IMS signaling according to flow charging, when at this moment needing GGSN statistics PDP Context flow, delete the flow of IMS signaling; (2) the IMS signaling produces different charge informations with non-IMS signaling bear among the PDP Context, be that GGSN is to IMS signaling and two Original CDR of non-IMS signaling output, which kind of charging way IMS signaling and non-IMS signaling are adopted, as be free of charge, by flow charging, by duration charge, by the incident charge, then carry out subsequent treatment in the charging center.
The flow process that GGSN carries out independent counting to the IMS signaling bear as shown in Figure 1, its step is as follows:
(1) among the GGSN static configuration to the charging regulation of IMS signaling bear;
(2) terminal is set up GPRS connection, the IP address of GGSN record P-CSCF (and Dynamic Host Configuration Protocol server and dns server);
(3) GGSN is according to the IP address of the P-CSCF (and Dynamic Host Configuration Protocol server and dns server) of record, packet among the PDP Context of this terminal is filtered, to send and come from the data of P-CSCF (and Dynamic Host Configuration Protocol server and dns server), use the IMS signaling bear charging regulation of static configuration.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with the people of this technology in the disclosed technical scope of the present invention; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
