Description
Technical field
The present invention relates to PTT on a kind of cellular system (PoC) service technique, internet protocol multimedia subsystem charging mark in particularly a kind of PoC service (ICID, IMS Charging Identity) distribution method.
Background technology
PTT (PTT) is a kind of semiduplex mechanics of communication, PTT business (PoC on the cellular system, PTT over Cellular) is the PTT business that on packet network, realizes of Open Mobile Alliance tissue (OMA) definition, adopts packet voice (VoIP) and half-duplex mode to realize.PoC service has been introduced a kind of brand-new communication pattern, be existing mobile system and traditional voice calling system can't provide, its internet protocol-based (IP) network, its cost is well below common mobile phone speech business, when satisfying calling in real time, can accomplish the expense minimum.
At present, OMA has formulated the PoC open specification based on 3GPP IP Multimedia System (IMS).So-called IMS is based on the professional control domain of the all-IP on the packet carrying network, can be applicable to multiple network such as mobile network or fixed network, the target of IMS is by personalization, the shielding user mode access, the degree of opening of control professional ability is for the user provides multimedia communication experiences.In the IMS territory, topmost functional entity is CSCF (CSCF) entity, MGCF (MGCF) entity, application server (AS) and home signature user server (HSS).Dialogue-based initiation protocol (SIP) is set up session between IMS entity and the IMS terminal.Described CSCF has three types: service call conversation control function (S-CSCF), Proxy Call Session Control Function (P-CSCF), query call conversation control function (I-CSCF).Here, in the IMS territory of supporting PoC service, so-called AS is the PoC service server (PoC Server) of handling PoC service, and described S-CSCF then connects PoC Server and is used for PoC service is controlled.
In addition, IMS is a kind of back-to-back user agent (B2BUA, Back to Back User Agent) business of type, AS wherein is that the PoC Server in the PoC service logically is made up of two UA, these two UA set up session with caller and called subscriber respectively and carry out back-to-back mutual.Like this, the session of the calling and called of setting up in the IMS territory is actually by the session between caller and the AS and each session between the called and AS and forms, then the IMS territory will distribute IMS charging identifier (ICID) that each session is wherein identified, and with each session association of setting up between the calling and called, thereby the IMS service conversation between the whole calling and called is chargeed according to the ICID that respectively is associated together.Described ICID is distributed by first relevant with current sessions in IMS territory entity, and will send other IMS entity in PoC service charging vector (P-Charging-Vector) header field in the ICID insertion SIP signaling message that be distributed.
According to the PoC service standard, to set up in the process at PoC session, ICID will be distributed for the user in the IMS territory, and this ICID is kept in the entities such as P-CSCF, S-CSCF and PoC Server.The session of PoC service normalized definition is set up mode and comprised: mode, the pre-established mode of session etc. are set up in common session.
Wherein, for a session, PoC Server is from being divided into two classes in logic: participate in (Participating) PoC Server and control (Controlling) PoC Server.Described ParticipatingPoC Server is used for receiving the SIP signaling from the IMS entity and resolves, and signaling is routed to the Controlling PoC Server of current sessions by the IMS territory; Described Controlling PoC Server is used for that process is set up in session and carries out integral body control, and session carried out integrated management, according to the SIP signaling that receives the service attribute of caller and called and current sessions is analyzed, and be sent to the SIP signaling called by the IMS territory.Like this, for a PoC service session, it comprises the session between the called and Controlling PoC Server of session between caller and the Controlling PoC Server and each, all corresponding ICID of each session, and this ICID can not share.
Because, the PoC service standard is based on the IMS standard, therefore, when adopting the common session of described PoC to set up mode, the distribution of ICID is identical with the ICID distribution method of above-mentioned IMS, that is: to set up the IMS entity of demand signalling be that calling terminal distributes ICID by at first receiving the SIP session in the IMS territory, and this ICID is included in Participating PoC Server and the Controlling PoC Server that sends current sessions in the P-Charging-Vector header field of SIP signaling message to the most at last, this Controlling PoC Server makes a call to called as the UA of caller then, for terminal called distributes ICID and sends the SIP signaling to called by the IMS territory.
Set up in the mode in above-mentioned common session, Participating/Controlling PoC Server needs to carry out the session parameter negotiation according to the session parameter in the SIP signaling message after receiving the SIP signaling, these session parameters need the IMS terminal to be sent to the IMS territory by the SIP signaling when making a call, usually to take than multibyte, therefore, the transport process of this SIP signaling in the IMS territory will take a large amount of on-air radio resources, and cause session long settling time.For addressing this problem, the PoC service standard has proposed the pre-established mode of session, promptly the PoC terminal is at first carried out the session parameter negotiation by invitation INVITE in the Session Initiation Protocol and Participating/Controlling PoC Server before session is set up, set up request Establish media message by Media Stream then, initiate follow-up session and set up process, and set up the session parameter that can omit this terminal in the process in follow-up session and handle through consultation, this moment, the PoC terminal will not be sent to the IMS territory by its session parameter, the byte number that its SIP signaling of uploading takies also will significantly reduce, thereby save interface-free resources.Here, described Establish media message can be carried by mention REFER message or the INVITE in the Session Initiation Protocol.
Because the pre-established mode of described PoC session is PoC service standard replenishing on the IMS standard base, when adopting the pre-established mode of PoC session, the distribution method that ICID in the process is set up in session does not still have standard at present and can follow.Therefore, in the pre-established process of existing P oC service conversation, can't carry out reasonable distribution to the ICID of caller and terminal called according to the IMS standard, like this, when adopting the pre-established mode of session to set up session, just may be owing to use inaccurate ICID to carry out ticket writing, and produce billing error.

Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
ICID distribution method provided by the invention is applied to the session of the pre-established mode of PoC service session and sets up in the process.Carry out session when pre-established in the PoC terminal, distribute ICID for it and preserves, finish the session parameter negotiation of this PoC terminal simultaneously by the IMS under it.When the follow-up session of this PoC terminal initiation is set up, distribute caller ICID for it once more by the IMS under this PoC terminal, Controlling PoC Server by current sessions distributes called ICID, again caller ICID and the called ICID that is distributed is kept among the IMS, and finishes session simultaneously and set up process.
Fig. 1 is session of the present invention ICID distribution method one preferred embodiment handling process schematic diagram when pre-established.As shown in Figure 1, concrete treatment step comprises:
Step 101:PoC terminal sends INVITE P-CSCF in the IMS territory under self, comprises at least in this INVITE: the user ID of this PoC terminal, show that this message is session parameters such as the sign of the pre-established message of session and IP address, port numbers, voice encoding and decoding format.
Because the pre-established mode of the session of PoC service is only at the PoC terminal, and P-CSCF is responsible for receiving the SIP signaling of present networks PoC terminal in the IMS territory, and therefore, the IMS entity that receives described INVITE here is P-CSCF.
Step 102: the P-CSCF of the described reception INVITE of step 101 is this PoC terminal distribution ICID, to identify the pre-established of this session.Then, this P-CSCF is included in the ICID that is distributed in the P-Charging-Vector header field of INVITE, again by I-CSCF or directly this INVITE is sent to S-CSCF under this PoC terminal.
Wherein, comprise in the transport process of INVITE of ICID at this, this INVITE the I-CSCF of process and/or S-CSCF will preserve wherein ICID.Here, the process that described INVITE transmits between each IMS entity belongs to known technology, and this paper is not described further.
Step 103: the S-CSCF under the above-mentioned PoC terminal is forwarded to PoC Server under this PoC terminal with the described INVITE of step 102, this PoC Server carries out according to the session parameter that carries in this INVITE that session parameter is consulted and preserves the final session parameter that obtains consulted, and the ICID that reads simultaneously in the P-Charging-Vector header field of this message is kept at this locality.
Here, when carrying out the session parameter negotiation, the session parameter that the PoC terminal sends first may not supported by this PoC Server, then PoC Server can return to the PoC terminal with the session parameter of self supporting, and finally the both sides that make alternately by the SIP signaling obtain the negotiation result of session parameter, the processing procedure that concrete session parameter is consulted belongs to known technology, and this paper is not described further.
Step 104～105: the described PoC Server of step 103 sends 200OK message to the IMS entity, the IMS entity again with this 200OK forwards to described PoC terminal, it is pre-established to finish session.
For a PoC service session, IMS and called affiliated IMS can be identical or different under the caller, and caller and called affiliated PoC Server also may be identical or different.In addition, for PoC session, Controlling PoC Server is unique, in the cluster conversation of interim definition, Controlling PoC Server is the affiliated PoC Server of calling party of session, in the cluster conversation of predefined or chat (Chat) pattern, Controlling PoC Server is the PoC Server under this management and group person, PoC Server then is Participating PoCServer under other user of session, therefore the Controlling Server of current sessions may be PoCServer under the calling and/or called, also may be other PoC Server, but all not influence validity of the present invention.Adhere to different IMS with caller separately with called below, and PoC Server is that the Controlling PoC Server of current sessions is an example under the caller, the distribution method of ICID was described in detail during the subsequent session to session of the present invention after pre-established was set up.
Fig. 2 for session of the present invention pre-established after, subsequent session is set up ICID distribution method one preferred embodiment handling process schematic diagram in the process.As shown in Figure 2, handling process comprises:
Step 201: caller PoC terminal is finished after the pre-established and session parameter of session consults by the described method of Fig. 1, sends the subsequent session request of setting up and be Establish media message P-CSCF among the IMS under this caller PoC terminal.
Here, because PoC Server has finished the session parameter negotiation in the pre-established process of session, and preserved the session parameter of this caller PoC terminal, therefore needn't carry session parameter in this Establish media message, PoC Server just can obtain the session parameter of this caller PoC terminal of self preservation by the calling identification in the identification Establish media message.Wherein, comprise a calling identification in this Establish media message and comprise one or more called identification.
Step 202: the described P-CSCF of step 201 is this caller PoC terminal distribution caller ICID, and this ICID is included in the S-CSCF that is forwarded in the P-Charging-Vector header field of described Establish media message under this PoC terminal.
Step 203: this S-CSCF is with the PoC Server of this Establish media forwards that comprises caller ICID under this caller PoC terminal, this PoC Server obtains the session parameter of this caller PoC terminal correspondence according to the calling identification in the Establishmedia message that is received, thereby sets up ready for session.
Step 204: PoC Server is that the Controlling PoC Server of current sessions is the called ICID of each called distribution according to each called identification in the Establish media message under the described caller.
Above-mentioned steps 201 to the Establish media message described in the step 204 by the REFER message bearing in the Session Initiation Protocol.
Step 205～step 206: this Controlling PoC Server is new Establish media message according to the structure of the called identification in the described Establish media of step 204 message session request of setting up, as the UA of caller PoC terminal to each called making a call, and the called ICID that step 204 is distributed is included in the P-Charging-Vector header field of this Establish media message, again this Establish media message is sent to each called affiliated IMS by the IMS under self.
The following stated is that the Controlling PoC Server ICID that certain is called is sent to the processing to PoC Server under should be called, for each called ICID of current sessions and corresponding called under PoC Server all will carry out processing as described below.
Step 207: the IMS under called transmits this Establish media message that comprises called ICID to called affiliated PoC Server.
Wherein, if the PoC Server under the caller is Participating PoC Server, and PoC Server has and only has one and for Controlling PoC Server under called, be that Controlling PoC Server distributes, preserves called ICID by PoC Server under called in the step 204 then, and need not execution in step 205 to step 207.If PoC Server is Participating PoCServer under the caller, and comprise Participating PoC Server among the PoC Server under called, then by the PoC Server under the caller this Establish media message is routed to the Controlling PoC Server of current sessions in the step 203, distribute each called ICID by Controlling PoC Server in the step 204, step 205 is sent to corresponding called affiliated PoC Server by this Controlling PoC Server with each called ICID to step 207; Because possible here situation comprises: one, called affiliated PoC Server is one or more, and be Participating PoC Server, two, called affiliated PoC Server is more than one, and one of them is Controlling PoC Server, and other is Participating PoC Server; Therefore, for described second kind of situation, when being Controlling PoCServer for one of them PoC Server under called, this Controlling PoCServer comprises self having jurisdiction over called whole called distribution ICID in the step 204, step 205 to the step 207 will except that self have jurisdiction over other called ICID called be distributed to corresponding each called under PoCServer.
Above-mentioned each Controlling PoC Server may adhere to different IMS territories separately with Participating PoC Server, also may belong to same IMS territory, be between the PoC Server in same IMS territory and can carry out Signalling exchange by the IMS territory under self, Signalling exchange is carried out in the IMS territory that the PoC Server that is in the different IMS territory then needs to belong to separately by it, concrete Signalling exchange details belongs to known technology, no longer describes in detail here.
Step 208: the PoC Server under called is sent to called PoC terminal by the IMS under called with this Establishmedia message, carries out called party answer and handles.
Here, PoC Server is when sending Establish media message under called, called ICID in this Establishmedia message P-Charging-Vector header field is kept at this locality, and delete this P-Charging-Vector header field, then this Establish media message is issued to called PoC terminal by IMS under called.
Because called response mode has multiple, such as: manual answering, automatic-answering back device etc., adopt different response modes, the called party answer of called affiliated PoC Server is handled different; And whether to have finished session pre-established according to called, and described called party answer is handled and also had any different; Therefore, the PoC Server under called carries out mode that called party answer handles also will be had multiplely, but all belong to known technology, and the non-framework of the present definition is no longer described among the figure.
Wherein, above-mentioned steps 205 to the described Establish media of step 208 message is carried by the INVITE in the Session Initiation Protocol.
Step 209～step 213: PoC Server returns to called affiliated IMS and accepts to reply ACCEPT message under called, the described Establish media of step 207 message is replied, this ACCEPT message is forwarded to the affiliated IMS of caller, the affiliated PoC Server of caller successively then, and finally arrive caller PoC terminal by IMS under the caller, successively the described Establish media of step 206, step 205, step 203 and step 201 message is replied, thereby calling and called are finished session and are set up process, can begin the media flow transmission of PoC service.Wherein, described ACCEPT message can or be confirmed the ACK message bearing by the 200OK in the Session Initiation Protocol.
In the above-mentioned processing procedure, each the IMS entity under the caller in the IMS territory when transmission comprises the Establish media message of caller ICID, all reads the P-Charging-Vector header field in this message, and wherein caller ICID is kept at this locality.Equally, called under each IMS entity in the IMS territory, when transmission comprises the Establish media message of called ICID, also all read the P-Charging-Vector header field in this message, wherein called ICID is kept at this locality.In addition, the Controlling PoC Server for current sessions is kept at this locality with caller ICID when it receives the Establishmedia message that comprises caller ICID, and also called ICID is kept at this locality after distributing called ICID.After each IMS entity relevant with the current sessions calling and/or called preserved calling and/or called ICID respectively, the IMS territory just can associate each ICID carried out ticket writing to current PoC service session, thus accurate billing.Here, the non-emphasis of the present invention of the method for described related ICID, detail as per another piece application for a patent for invention file of the applicant, this paper no longer describes in detail.
In sum, using the inventive method can be when adopting the pre-established mode of PoC session to set up session, be the caller and the called distribution ICID of current sessions, the perfect ICID distribution method of existing PoC service, thereby can be correctly to the processing of chargeing of session relevant action.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.All any modifications of being done within the spirit and principles in the present invention, be equal to replacement, improvement etc., all be included in protection scope of the present invention.
