Embodiment
With reference to figure 2, illustrate an embodiment who the calling in the circuit-domain network is routed to the system configuration of packet field network provided by the invention.As shown in the figure, MS50 is user's a mobile terminal device, can be dual-mode terminal (both having supported circuit-domain network also to support packet field network).For providing the communication network of service, described MS50 comprises PLMN (public land mobile radio communication) 100 and IMS (IP Multimedia System) network 200.Wherein PLMN100 is a circuit-domain network, and IMS network 200 is a packet field network.Wherein, described PLMN100 comprises MSC105 and HLR (attaching position register) 110.Certainly, comprise also among the described PLMN100 that BSC (base station controller) etc. is responsible for the network element entity of the signal access network of MS50 and other network element entity (VLR for example, Visited Location Registor), but these technology belong to the technology that those of ordinary skills know, and little with enforcement relation of the present invention, therefore omit.Described MS50 can intercom mutually with MSC105, and described MSC105 can intercom mutually with HLR110.
What deserves to be explained is that " user " and " terminal " or " user terminal " otherwise have same implication unless otherwise mentioned herein.
With reference to figure 2, described IMS network 200 comprises MGCF205, I/S-CSCF210 and NeDS215.Wherein, described MGCF205 can communicate by letter with MSC105.Described I/S-CSCF210 can intercom mutually with MGCF205 and NeDS215.
With reference to figure 3, illustrate the functional structure chart of MSC105 among Fig. 2.As shown in the figure, MSC105 comprise receiving element 106, the acquiring unit 107 that connects with these receiving element 106 lotus roots, the generation unit 108 that connects with acquiring unit 107 lotus roots and the transmitting element 109 that connects with these generation unit 108 lotus roots.MSC105 also comprises memory cell 104, and this memory cell 104 connects with acquiring unit 107 lotus roots.
Some beginnings are exhaled the business of triggering if described MS50 has contracted in circuit-domain network, can realize goal of the invention of the present invention by revising these business.
In circuit-domain network (for example PLMN100 among Fig. 2), there is a kind of additional beginning to exhale the business of triggering, be called " SPINI (Subscriber PIN Intercept) " business.Example context with Fig. 2 is an example, and after MS50 had contracted this business, if the call number that MS50 initiates meets signatory trigger condition (as international long-distance, national distance, all-calls etc.), MSC105 will be toggled to HLR110 to calling.To the MS50 playback, require MS50 input PIN code by HLR110.If MS50 has imported correct PIN code, then HLR110 returns and calls out the indication that continues, and continues replay call by MSC105.In a specific embodiment of the present invention, make MSC105 get access to routing iinformation by revising this business.
With reference to figure 4, illustrate the data flow of an embodiment that the calling with in the circuit-domain network based on the enforcement environment of Fig. 2 routes to the method for packet field network.In this embodiment, the MS50 SPINI business of having contracted, and trigger condition is " all-calls ".Reference diagram 3 and Fig. 2 in the time of with reference to figure 4, as shown in the figure, described method comprises:
1, MS50 makes a call in PLMN100, and call number (i.e. Cld Number among the figure) is the number of MS2, and promptly MS2 is called subscriber's a terminal;
2, MSC105 receives described calling by receiving element 106, also be that MS50 initiates calling service, exhale the triggering business information according to the beginning of MS50, identify the MS50 SPINI business of having contracted, to send the routing iinformation request to HLR110 according to this professional requirement, just obtain the step of routing iinformation, MSC105 is by acquiring unit 107 these steps of control.MSC105 can send described routing iinformation request by the ORREQ message of MAP signaling group.3, after described HLR110 receives described routing iinformation request, determining MS50 is dual-mode terminal, then do not need to resemble to handle and require MS50 input PIN code the normal SPINI business, but generate described routing iinformation and this routing iinformation is sent to MSC105 with the form of routing iinformation request-reply.In described routing iinformation, call number is modified the routing number into IMS network 200, and can carry original call number (being the number of MS2) in this routing iinformation in the lump.The mode of carrying can be to indicate with a special parameter, can add before the original call number that also the routing number of IMS network 200 is as call number.This step is exactly a routing iinformation request-reply step, and HLR110 can send by the ORREQ message of MAP signaling group.
4, after MSC105 receives described routing iinformation, generate outbound call, the call number of this outbound call is exactly the call number in the described routing iinformation, i.e. the routing number of IMS network 200.And in described outbound call, also carry original call number (being the number of MS2) simultaneously, i.e. called number.This work is carried out by the generation unit among the MSC105 108.After generating described outbound call, described outbound call is sent, can realize by the IAM signaling in the ISUP signaling group by the transmitting element 109 of MSC105.This outbound call will be routed on the MGCF205 in the IMS network 200 according to call number;
5, described MGCF205 is toggled to NeDS215 by I/S-CSCF210 with this outbound call after receiving described outbound call, can send by structure SIP signaling, request URI field in this SIP signaling extends this as the routing number of the IMS network of receiving from MSC205 200, and in the special header field of another one original called number (number of MS2) is inserted.NeDS215 carries out subsequent treatment after receiving this outbound call.
So far, the calling of MS50 in PLMN100 routed in the IMS network 200.In this embodiment, do not need MSC105 to support intelligent network, only need on original business (being the SPINI business) basis, to improve, just can realize distinguishing the user property of MS50, particular terminal is occurred in calling route switching in the circuit-domain network to the purpose of the packet field network of this particular terminal ownership.
What deserves to be explained is, if original just signatory certain number triggering SPINI business that has of MS50, such as " international long-distance triggering ", so for the original signing service of MS50 is not influenced, HLR110 should be after dispose " all-calls " triggers, and detects the business that the current preparation of MS50 carries out again and whether satisfies other signatory trigger condition, if satisfy, then still need trigger original PIN code interception service, MS50 is carried out playback requirement MS50 input PIN code.Because judged originally that whether business that MS50 carries out satisfies trigger condition was the judgement of carrying out at MSC105, changed at HLR110 now and having judged, so HLR110 must consider the situations such as roaming of MS50, promptly MS50 this business of whether carrying out in the roaming place judges whether the current service attribute that carries out of MS50 satisfies professional trigger condition.
What deserves to be explained is, the described routing iinformation that obtains can also be realized by following manner: send to MSC105 generate this routing iinformation by HLR110 when the signatory SPINI service log-on of MS50 after, be stored in the memory cell 104 of MSC105, when MS50 makes a call, MSC105 need not go HLR110 to go up acquisition again, but directly obtains on memory cell 104 by internal interface.Thus, saved the mutual of MSC105 and HLR110 during calling, thereby shortened connecting time.In another specific embodiment below, more detailedly introduced this mode of obtaining routing iinformation.
In circuit-domain network (for example PLMN100 among Fig. 2), also have a kind of additional beginning to exhale the business of triggering, be called " single number exhalation " business.Example context with Fig. 2 is an example, and after MS50 had contracted this business, any calling that MS50 initiates all can be connected in the fixed number of appointing in advance went, and we can claim this fixed number to be " restriction number ".In another specific embodiment of the present invention, make MSC105 get access to routing iinformation by revising this business.
