Description
Technical field
The present invention relates to the communications field, relating in particular to a kind of is the network and the method for the portable terminal access multimedia service of non-group mode.
Background technology
IP Multimedia System is that 3GPP is the functional module that increases newly in the WCDMA R5 system, is responsible for providing relevant controlling mechanism for IP-based multimedia service (as VoIP, video conferencing service etc.) on the packet domain connection basis.This system's major function entity comprises: CSCF (CSCF), MGCF (MGCF), media resource function (MRF).Mainly acting as of these several functional entitys:
1, CSCF (CSCF):
IP Multimedia System comprises three kinds of different CSCFs: inquiry CSCF (I-CSCF), proxy CSCF (P-CSCF), serving CSCF (S-CSCF).
P-CSCF is the first step of UE contact IMS.It will be given to a sip server that is positioned at home network before UE receives sip message, vice versa.According to the set of rule (as adress analysis and possible modification) that Virtual network operator is set, P-CSCF also can revise a request of sending.The function of I-CSCF provides the inlet of home network, and the topological diagram of home network is network concealed to other, and can select S-CSCF flexibly.S-CSCF finishes the conversation control function of UE, is routed to external network comprising the session of will start, and the session of termination is routed to the network of visit.When the SIP conversation request of an incoming call was managed business, whether the S-CSCF decision needed an application server to accept relevant information.This decision is based on the information of receiving from HSS or other source (as application server).The detail record that all CSCF functions could generate and export calling is used for the processing of chargeing.
2, home subscriber server (HSS):
HSS is a given user's a master data base by attaching position register (HLR) and AUC (AUC) evolution.It is an entity that comprises register information, is used for network enabled entity handles call/session.It also supports authentification of user and authorization function (AAA), and by services such as authentication, mandate, title/address resolution, HSS helps call control server to finish routing/roaming function.
HSS is responsible for preserving following and user-dependent information: (1) user ID, numbering and address information; (2) user security information is used for the required network insertion control information of authentication and authorization; (3) customer position information on rank between system, i.e. HSS process user registration, the positional information between the while storage system etc.; (4) user's summary info.
Based on above information, HSS can also provide support to the entity of different control system (circuit domain control, the control of PS territory, the control of IP multimedia etc.).
3, MGCF (MGCF):
For a particular network, MGCF is the destination node of PSTN/PLMN network.It has following function: the control of (1) call state, promptly the part relevant with the media channel connection among the MGW controlled; (2) communicate with CSCF; (3) for the calling from legacy network, MGCF selects corresponding C SCF according to their routing number; (4) conversion between realization legacy network call control protocol (as ISUP R1/R2) and the R4/R5 calling network control protocol; (5) MGCF can the receiving belt external information, then it is sent to CSCF/MGW.
4, Multimedia Resource Function (MRF):
The function that MRF realizes is: (1) provides Multi-Way Calling and multimedia conferencing function, and it is identical with the function of multipoint control unit (MCU) in the network H.323; (2) in many ways/multimedia conferencing in, be responsible for bearer service control jointly with GGSN and MGW; (3) can communicate with CSCF, in many ways/Multimedia session carries out business authentication.
Along with development of Communication Technique, the carrying of next generation communication network has begun to use instead IP comprehensively, development from communication network, no matter be code division multiple access (CDMA) or global system for mobile communications (GSM)/Wideband Code Division Multiple Access (WCDMA) (WCDMA), all experienced from the legacy circuit-switched networks network to control and carried the IP packet network of separation again to the such evolution process of the multi-media network of all-IP.
The example that is evolved to CDMA: the cdma network carrying is from initial Time Division Multiplexing carrying, to having defined traditional travelling carriage territory (LMSD) and two evolution stages of multimedia domain, MMD (MMD), select IP to select, and the A interface is selected IP on bearer types as the carrying of core net and Access Network; CDMALMSD stage circuit domain has realized separating of carrying and control, supports IP on bearer types; The MMD version is then introduced IP Multimedia System (IMS) territory in core net, interface signaling IPization (using the SIP signaling).Final goal in this evolution process is to provide professional by unified IMS network, can but in the process of IMS evolution, how the legacy circuit-switched stage that has existed be linked into the IMS network to enjoy the multimedia service that enriches that IMS provides with the non-IMS the terminal how network equipment of controlling the carrying separation phase continues to play a role, existed in a large number in a large number? this is a problem that needs solution.
The solution that has a kind of " OVERLAY " in the prior art, as shown in Figure 1, Mobile Switching Center Server among the figure (MSC SERVER) is the control core of traditional circuit domain, it is connected the control mobile subscriber by the A interface signaling on the one hand with wireless access network (RAN), be connected with attaching position register (HLR) by the MAP signaling on the one hand the user is carried out data management and location management.The intercommunication in circuit domain and IMS territory then is to finish by MGCF (MGCF) unit, its one side and MSCSERVER carry out intercommunication by ISDN(Integrated Service Digital Network) (ISDN) User Part (ISUP) signaling, one side and CSCF (CSCF) unit carry out intercommunication by the Session Initiation Protocol signaling, it plays the translation function of ISUP and SIP signaling therein, and its control media gateway of signaling H.248 (MGW) of can also conversing is carried out the conversion that possible TDM carries to IP.This scheme independently is provided with circuit domain core net and multimedia domain, MMD core net, and intercommunication is carried out by MGCF+MGW in the centre.Conventional terminal will at first be routed to MGCF by circuit domain control signaling such as ISUP etc. in the calling that circuit domain takes place, and issues multimedia domain, MMD after being converted into the SIP signaling by MGCF, is undertaken by multimedia domain, MMD that business controlled again and charging etc.Signaling after will handling again after multimedia domain, MMD disposes is transmitted back circuit domain via MGCF and is continued.
But there are the following problems for this scheme:
At first, terminal can not can only be routed to the IMS territory in the registration of IMS territory in bid.The IMS territory just is merely able to ordinary call class business is controlled, and can not provide more IMS professional as presenting business (Presence), click-to-dial, networking telephone book etc. to terminal.
Secondly, call signaling all will carry out OVERLAY to the IMS territory, causes signaling circuitous.
Once more, this scheme will be carried out the intercommunication of circuit domain control signaling (as ISUP) and SIP signaling, and a lot of supplementary services all can't completely realize.
