Embodiment
With embodiment the present invention is described in further detail with reference to the accompanying drawings below:
For realizing the object of the invention, basic skills of the present invention is exactly that the Access Network of circuit core net as the IMS territory is connected with the multimedia domain, MMD core net, by HLR position at circuit domain core net, traditional mobile terminal is registered to the IMS territory, makes traditional mobile terminal can initiate/receive the SIP session service in the IMS territory.For this reason, in order to adapt to present two kinds of different network architectures---carrying and control separation architecture and non-bearing and control separation architecture, the present invention has designed two kinds of different network models.
As shown in Figure 2, under carrying and the control separation architecture, network model comprises multimedia domain, MMD core net and circuit domain core net, circuit domain core net comprises a MSCe who is connected with the RAN communication (Mobile Switching Center emulation, have control and simulate entity with the mobile switching centre of carrying separating power)/VLR (Visitor Location Register, Visited Location Registor), MSCe/VLR has control to simulate entity with the mobile switching centre of carrying separation function, also comprises the mobile access user agent (MUA) who is connected with the MSCe/VLR communication; CSCF is the control kernel entity in IMS territory, it is responsible for session control and professional the triggering, HSS is the entity of storage user service data in the IMS territory, AS is the server that various concrete applied business are provided to the user, add the responsible entity that charges (as CCF, Charging Collecting Function), just constituted the core network in IMS territory.MUA is connected with the CSCF communication, with circuit domain core net as the Access Network access domain of multimedia.Under above networking situation, Media Stream will pass through the A interface, carries out intercommunication by the media gateway MGW under each network.RAN can be the TDM carrying, also can be the IP carrying; Not being both of a this networking and a prior art intercommunication mode maximum of networking: CS territory and IMS territory are two territories arranged side by side during the intercommunication mode, and the CS territory drops to the Access Network in IMS territory in this scheme.RAN and MSCe/VLR are responsible for MS is linked into CS territory network among the figure, and it is mutual to pass through MAP signaling and broadband call control signaling and MUA, and MUA then is responsible for the user is linked into the IMS territory.
As shown in Figure 4, under non-bearing and the control separation architecture, network model comprises multimedia domain, MMD core net and circuit domain core net equally, MSC in the circuit domain core net of this moment is not for having control and the mobile switching centre of carrying separating power, therefore the circuit core net has increased the Softswitch with control and carrying separation function that is connected with MSC, MUA, media gateway MGW, Softswitch carries the arrowband call control signalling of mobile station with control and separates, and be converted to broadband control signaling and MUA mutual.MGCF as shown in Figure 4, under this networking situation, behind the Media Stream process A interface, the media gateway MGW of controlling by the MGCF entity in IMS territory carries out intercommunication.MSC/VLR is mutual by MAP signaling and MUA, the arrowband call control signalling of MSC/VLR then through MGCF carry be converted to broadband control signaling after control separates and MUA mutual.Or as shown in Figure 5, Softswitch is the Tandem SW of tandem soft switch office, and under this networking situation, behind the Media Stream process A interface, the media gateway MGW of controlling by Tandem SW carries out intercommunication.MSC/VLR is mutual by MAP signaling and MUA, the arrowband call control signalling of MSC/VLR then through Tandem SW carry be converted to broadband control signaling after control separates and MUA mutual.This network model is compared carrying and the scheme of controlling under the separation case, maximum difference is the ability that MSC itself does not have control media gateway MGW and the intercommunication of interoffice broadband signalling, therefore need calling is transferred on the Softswitch with control and carrying separating power (as MGCF or TandemSW), by after having control and the tandem exchange of carrying separating power carrying out signaling and carrying separates, again signaling is linked into the IMS network by MUA.
No matter whether the traditional circuit domain network has realized that control separates with carrying, the key of above network model is a newly-increased entity that is called MUA (Mobile User Agent moves and inserts the user agent).Its function constitutes as shown in Figure 3: comprise HLR functional module, MAP signaling processing module, SIP signaling processing module, broadband signalling processing module and billing interface module, the following description of the interactive relation between each functional module:
● after the MAP signaling processing module of MUA is received the signaling that MSC sends, forwarding the HLR functional module to handles, the HLR module judges according to the signatory situation of user whether the user need be linked into the IMS territory, as not needing then HLR handling process according to traditional circuit domain, return result by the MAP signaling processing module to MSC, otherwise mail to the IMS territory by the SIP signaling processing module;
● the broadband signalling processing module of MUA through the SIP signaling processing module, is that sip message mails to the IMS territory with this message conversion after receiving the broadband call control signaling of soft switch office;
● after the SIP signaling processing module of MUA is received the SIP signaling in IMS territory, obtain user profile to the HLR functional module after, selecting through logic determines is that the SIP signaling is converted to broadband call control signaling, mails to soft switch office by the broadband signalling processing module; Still mail to MSC through the MAP signaling processing module;
● the billing interface module of MUA can mail to the IMS territory with the correlometer charge information according to reception of SIP signaling processing module or the sip message that sends.Billing interface mainly is for the charge information with Access Network and core net associates, and its concrete operations comprise and distribute charging identifier, send as the charging signaling of Diameter form, RADIUS form or certain user-defined format etc.
The function of MUA is:
1. the function that has traditional HLR can select the user only to be registered to the IMS territory according to the signatory situation of user, only is registered to the CS territory, or both's registration;
2. as SIP UA, the underground traditional mobile terminal of visit that replaces roaming in MSC or MSCe management carries out functions such as SIP registration and initiation/reception SIP session in the IMS territory;
3. can realize the bi-directional conversion between MAP signaling and the SIP signaling, thereby finish the function that traditional mobile terminal is inserted the IMS territory;
4. have the function that charge information is provided to the IMS territory, billing interface can be provided.
In above several network models, MUA has substituted the HLR of traditional circuit domain fully, even the user need not be registered to the IMS territory, also will be handled by MUA.So the data volume that MUA need handle is very big.Under the following networking situation of enumerating, MUA only handles the user that need be registered to the IMS territory, and the user that need not be registered to the IMS territory is still handled by the HLR of traditional circuit domain.
Embodiment one shown in Figure 6, under this networking, after the HLR of traditional circuit domain receives the MAP signaling of MSC or MSCe, the initiator who judges this signaling is for being registered to legacy user's (can learn from this user's signatory situation) in IMS territory, then signal switching is handled to MUA by MAP signaling or self-defining interface, and the signaling that MUA sends is changed into the MAP signaling issue MSC or MSCe, promptly be registered under the situation in IMS territory the user, HLR is only as Signaling Transfer Equipment, and concrete service logic judgement is realized by MUA.And can close with HLR from MUA physically and to establish.Embodiment two shown in Figure 7, under this networking, FORK entity (signaling catching equipment) interception MSC or MSCe mail to the MAP signaling of HLR, message is mail to MUA, MUA judges that the initiator of this signaling is for being registered to the legacy user in IMS territory, then carry out alternately, and follow-up signaling is issued MSC or MSCe by the FORK entity with the IMS territory; Otherwise MUA arrives HLR to forwards by the FORK entity, handles this signaling by HLR.MUA can close with the FORK entity and establish equally, physically.
According to above network model, no matter whether the traditional circuit domain network has realized that control separates with carrying, the registration process of traditional mobile terminal may further comprise the steps as shown in Figure 8:
1. traditional mobile terminal is initiated position updating request at the wireless access network RAN on visit ground;
2. the MSC on visit ground or MSCe find the MUA of its ownership and initiate location registers according to the IMSI (InternationalMobile Subscriber Identity international mobile subscriber identification code) of portable terminal;
3.MUA (Proxy CSCF proxy call conversation control function entity is initiated registration to the P_CSCF in IMS territory to act on behalf of this user as SIPUA;
4.P_CSCF utilize the defined flow process in IMS territory to determine the S_CSCF of user attaching, and initiate registration;
5.S_CSCF (Serving CSCF, serving CSCF) returns and succeeds in registration;
6.P_CSCF return to MUA and to succeed in registration;
7.MUA register successfully to the MSC home position;
8.MSC home position upgrades successfully.
