Description

Speech business route control method and network frame based on the business triggering

Technical field

The present invention relates to the network communications technology field, be specifically related to a kind of speech business route control method and network frame that triggers based on business.

Background technology

From 3GPP R5 (the 3rd Generation Partnership Project 3rd Generation Partnership Project) stage, UMTS (universal mobile telecommunications system) core net is divided into CS (circuit switching), PS (packet switching) and three subsystems of IMS (IP Multimedia System).

CS territory (Circuit Switched Domain circuit commutative field) is used for providing to the user connection of Circuit Service.The CS territory mainly comprises: MSC (MSC Server/CS-MGW, Mobile Switch Center Server/CS-MediaGateWay, Mobile Switching Center Server/circuit domain-media gateway), GMSC (Gateway MSC gateway MSC) and IWF (Inter Working Function, IWF).Wherein, MSC finishes the exchange and the signaling controlled function of circuit switched type business; GMSC is the MSC that finishes mobile subscriber's routing addressing function in a certain network, can close with MSC if set up separately; IWF and MSC are closely related, finish the signaling translation function between PLMN (public land mobile net) and ISDN (integrated services digital network), PSTN (public telephone switching network), PDN (Packet Data Network packet data network), thereby the realization network interworking, the concrete function of IWF is closely related with the kind of professional and network.

PS territory (Packet Switched Domain) is used for providing to the user connection of packet-type business, and the PS territory mainly comprises: GSN (GPRS Support Node), BG (borde gateway), HLR/AuC (Home Location Register/authentication center), VLR (VLR Visitor Location Register), EIR (equipment identity register), MSC etc.Wherein, GSN finishes the transmission of Packet Service user's grouping bag, GSN comprises SGSN (Serving GPRS Support Node) and GGSN (Gateway GPRS Support Node), SGSN provides being connected of core net and wireless access system BSS, RNS, finish the functions such as mobile management, session management of multicomponent data business, with management MS moving and communication service in the mobile network; GGSN is the interface between mobile communication system and other public data network, and simultaneously, GGSN also has the function of inquiring position information.In addition, SGSN and GGSN all provide charge information.BG be used to finish two between GPRS network intercommunication, guarantee the fail safe of network interworking.HLR is used to finish the management of user contracting data and positional information, user contracting data such as MSISDN, IMSI, PDPADDRESS, signatory telecommunication service and supplementary service and the professional scope of application thereof etc., positional information such as MSRN, MSC/VLR number, SGSN number, GMLC etc.AUC is mainly used in storage user's authentication arithmetic and key.VLR is used to handle the various data messages of visitor.EIR is used to store customer equipment identification IMEI information.

IMS is a subsystem that is superimposed upon in the WCDMA network that increases in the 3GPP R5 stage on the existing packet domain, adopt the bearer path of packet domain for its upper strata control signaling and media delivery, and introduce Session Initiation Protocol as professional control protocol, utilize simple, the easy expansion of SIP, media combination characteristics easily, by business control is separated with carrying control, provide abundant multimedia service.Major function entity among the IMS comprise functions such as control user registration, session control conversation control entity CSCF, provide miscellaneous service logic control function application server AS, manage the home subscriber server HSS of user contracting data concentratedly and be used to realize MGCF/IM-MGW (MGCF) with the circuit switching net interconnecting.The user is by current location agent node P-CSCF access IMS, and session and professional triggering control reach with the business control of AS and then finished by the home domain service node S-CSCF of its registered place alternately.

HSS in the IMS system is the superset of HLR, can compatible HLR on the function, but because factors such as networking process, HSS and CS/PS HLR adopt situation about setting up separately probably in the concrete networking.

The IMS framework of 3GPP standard definition has solved the roam charge that the required solution of multimedia service is provided under the IP carrying comprehensively, QoS (service quality), but the problems of operation that safety guarantee etc. are crucial, its framework and thinking have obtained industry and have generally acknowledged, 3GPP2, TISPAN has all carried out the definition of corresponding IP multi-media network framework and business system with the 3GPP model as basis and reference, 3GPP has also begun to insert and UMTS intercommunication such as I-WLAN (Interworking of WLAN at WLAN (WLAN (wireless local area network)), the WLAN intercommunication), fixed broadband inserts IMS such as FBI (Fixed Broadband access to IMS, fixed broadband inserts IMS) and towards the all-IP net such as the AIPN subject studies such as (All-IP Network complete IP networks) of multiple access technology, the user can signatory insert IMS by single multimode terminal or polytype different terminals via the Access Network of different access technologies according to it, with what obtain to unify, the multimedia service that comprises VoIP (Voice over IP, IP-based voice) business etc.

Because the business platform of IMS framework can provide IP-based speech business equally, it is the VoIP business, and operator can at based on the speech business in CS territory with implement different charging rates respectively based on the speech business in IMS territory, therefore, for unfounded call/session still, need select the route of user between CS territory or IMS territory neatly according to the routing policy of operator and user's preference setting; And, because operator also can provide respectively in different regions based on the speech business in CS territory or based on the speech business in IMS territory, like this, because user's mobility, for the call/session of having set up, when the user speech business takes place in CS territory and IMS territory is switched, need to guarantee the continuity of call/session, to guarantee that speech business is two seamlessly transitting of same area not.

At present, 3GPP has just passed through research CS calling and has passed through IP-CAN (IP-Connectivity AccessNetwork IP, connective access network) insert the work problem of business continuance problem between the VoIP business that IMS provides, the emphasis of research contents concentrates on route control and switches two aspects.Solving on user's the Route Selection problem, 3GPP has proposed two kinds of solutions, wherein, a kind ofly is based on professional the triggering and realizes, another kind is based on and strengthens that HLR/HSS realizes.

Trigger realization route controlling schemes as shown in Figure 1 based on business:

Among Fig. 1, the business in CS territory triggers based on CAMLE (Customized Applications for MobileNetwork Enhanced Logic, mobile network strengthen professional customization and use) and realizes, control realizes based on AS in the business triggering in IMS territory.When MSC receives the calling of CS territory, trigger callee side CAMEL business according to user contracting data, set up professional control relation with gsmSCF as routing decision point.When S-CSCF receives the calling of IMS territory, trigger professional control according to user contracting data, set up professional control relation with AS as routing decision point.As the gsmSCF of routing decision point and AS then store routing policy, obtain from GMSC/S-CSCF according to the routing policy utilization and carry out routing decision with the mutual needed information of routing decision that obtains of HLR/HSS, and the professional control relation set up of utilization and GMSC/S-CSCF is carried out route and is controlled.

For a calling from the CS territory, the concrete processing procedure that trigger to realize route control based on business is: when MSC receives the calling of CS territory and triggers callee side CAMEL when professional according to user contracting data, MSC and gsmSCF set up professional control relation, at this moment, routing decision point gsmSCF can be according to the called subscriber condition information that obtains to HLR or HSS inquiry, and in conjunction with operator's routing policy and user's preference setting, decide user's routing decision, and carry out follow-up route and control, in the time of need continuing in the CS territory route as judge the user as gsmSCF, then gsmSCF issues Continue to the MSC with gsmSSF function, after the MSC continuation is fetched called subscriber's roaming number according to called number to HLR like this, in the CS territory, route to called; For another example when gsmSCF judges the called subscriber and need forward in the IMS territory route to, then gsmSCF issues connect to the MSC with gsmSSF function, carry a number that points to MGCF in the connect operation, gsmSSF routes the call to MGCF according to the number of this sensing MGCF, then, continue in IMS territory route by MGCF, finished the calling of initiating at the CS territory like this and in the IMS territory, routed to called control.

For calling, after carrying out routing decision, gsmSCF routes to the CS territory or the handling process in IMS territory as shown in Figure 2 from the CS territory.

Among Fig. 2, receive Setup (call setup) signaling that incoming call signaling IAM (InitialAddress Message initial address message) or call subscriber terminal are initiated at step 2-1, MSC with gsmSSF function.

Send SRI according to called subscriber's number to HLR to step 2-2, MSC/gsmSSF, HLR returns called subscriber's T-CSI (callee side CAMEL Subscription Information) to MSC/gsmSSF.

Send IDP (InitialDetected Point initial Detection Point), trigger intelligent business according to the above-mentioned T-CSI that returns to corresponding SCP to step 2-3, MSC/gsmSSF.

To step 2-4, gsmSCF service logic according to the definition of the service key among the CSI of gsmSSF triggering, optionally and HLR mutual, carry out the inquiry of routing decision relevant information, as send ATI/ATSI (Any TimeInterrogation/Any Time Subscription Interrogation inquires about/signatory at any time inquiry at any time), log-on message and the related service CAMEL-Subscription-Information of inquiry called subscriber in the CS territory to HLR.

To step 2-5, gsmSCF service logic according to the definition of the service key among the CSI of gsmSSF triggering, optionally and HSS mutual, carry out the inquiry of routing decision relevant information, as send ATI/ATSI inquiry, log-on message and the related service CAMEL-Subscription-Information of inquiry called subscriber in the IMS territory to HSS.

Above-mentioned steps 2-4 and step 2-5 do not have processing sequence successively.

According to its routing decision relevant information of obtaining,, determine the routing policy of this calling to step 2-6, gsmSCF as the routing policy information of log-on message, related service CAMEL-Subscription-Information and gsmSCF self storage of called subscriber in CS territory, IMS territory.

Issue Continue operation according to its routing policy of determining this calling to gsmSSF to step 2-7, gsmSCF, indicating call continues route in the CS territory, or issues the Connect operation to gsmSSF, indicates this calling route in the IMS territory.

The indication that issues according to gsmSCF to step 2-8, gsmSSF to this calling in the CS territory or the IMS territory carry out route.

For a session from the IMS territory, triggering the detailed process that realizes route control based on business is: when the S-CSCF in the IMS territory receives the calling of IMS territory, according to iFC (initial Filter Criteria initial filter standard or norm) criterion session is triggered on the AS, at this moment, routing decision point AS can be according to inquiring about the called subscriber condition information that obtains from HLR or HSS place, and in conjunction with operator's routing policy and user's preference setting, decide called routing decision, and carry out follow-up route and control, in the time of need continuing in the IMS territory route as judge the called subscriber as AS, AS still carries original called party information in the INVITE that sends to S-CSCF, like this, S-CSCF continues to finish at IMS according to called party information and is routed to called session control; For another example when AS judges the called subscriber and need forward in the CS territory route to, AS carries an E.164 number that points to MGCF in the INVITE that sends to S-CSCF, like this, S-CSCF will talk about through BGCF according to the number of this sensing MGCF and route to MGCF, then, MGCF will talk about and route to the CS territory, thereby, finish the session of initiating at the IMS territory and in the CS territory, routed to called control.

For calling, after carrying out routing decision, AS routes to the CS territory or the handling process in IMS territory as shown in Figure 3 from the IMS territory.

Among Fig. 3, receive session signaling Invite at step 3-1, S-CSCF.

To step 3-2, step 3-3, S-CSCF carries out business according to the filter information among the iFC to session to be triggered, and transmits this Invite to AS.

Optionally mutual to step 3-4, AS with HLR according to the service logic of definition, carry out the inquiry of routing decision relevant information, as sending ATI/ATSI, inquire about log-on message and the related service CAMEL-Subscription-Information of called subscriber in the CS territory to HLR.

Optionally mutual to step 3-5, AS with HSS according to the service logic of definition, carry out the inquiry of routing decision relevant information, as sending ATI/ATSI, inquire about log-on message and the related service CAMEL-Subscription-Information of called subscriber in the IMS territory to HSS.

Above-mentioned steps 3-4 and step 3-5 do not have processing sequence successively.

To step 3-6, AS routing decision relevant information, determine the current routing policy of this session as the routing policy information of log-on message, related service CAMEL-Subscription-Information and AS self storage of called subscriber in CS territory and IMS territory according to the above-mentioned called subscriber who obtains.

Send Invite according to the routing decision of determining to S-CSCF to step 3-7, AS, if this session need continue route in the IMS territory, then still carry original called subscriber's address information among the Invite, be original Req-URI information, like this, S-CSCF can route to called P-CSCF with this session according to the domain name of original Req-URI, in the IMS territory with this conversation switching to the called subscriber; If this session need be in the CS territory route, then carry an amended called address information in the Invite operation, as an E.164 number that points to MGCF, S-CSCF routes to MGCF with this session through BGCF according to the E.164 number of this sensing MGCF, then, by MGCF this session is routed to the CS territory.

To step 3-8, the S-CSCF Invite that transmission comes according to AS route is carried out in session, make session can in CS territory or IMS territory, obtain handling.

From the description of technique scheme as can be known, present triggers in the controlling schemes that realizes called route based on business, and when calling came from the CS territory, the routing decision point was the gsmSCF in the CS territory; When session came from the IMS territory, the routing decision point was the AS in the IMS territory.Belong to two operators for the operator that has CS territory and IMS territory simultaneously or CS territory and IMS territory, need to guarantee that different routing decision points have synchronously and the routing decision data that are mutually related, to guarantee speech business called route uniformity of treatment in CS territory and IMS territory, as wishing to limit certain pernicious overdraw user's voice when operator when professional, the ODB data in CS territory can be set this user, gsmSCF is when doing routing decision, according to the ODB data that are provided with this user's voice business is limited, same, the routing decision point AS in IMS territory also should limit this user's voice business when doing routing decision; For another example, routing decision point gsmSCF routes the call to the IMS territory according to the routing decision data in CS territory, and routing decision point AS should route to the CS territory again according to this session of routing decision data limit in IMS territory.

Do not consider two different routing decision points of gsmSCF and AS how to make a strategic decision data synchronization and related question in the present speech business route control method, thereby can not guarantee the consistency of speech business route control and treatment in CS territory and IMS territory, and, also can make call/session between two territories, carry out unconfined route circulation, reduce the success rate of speech business.

Be that speech business route control method between CS territory and the IMS territory is that example is elaborated to the technical scheme that the present invention improves below with foreign lands.

The speech business route control method one that triggers based on business of the present invention as shown in Figure 4.

Among Fig. 4, the routing decision point in CS territory and IMS territory only is one, and the routing decision point gsm-SCF that is about to the IMS territory is arranged in the entity at gsmSCF place in CS territory.Like this, will store the user in the entity at the gsmSCF place in CS territory in the routing policy information in CS territory and user routing policy information in the IMS territory.

When the routing decision point gsm-SCF with the IMS territory is arranged among the gsmSCF in CS territory, also need in the IMS territory, increase the CAMEL function, promptly in the IMS territory, increase IM-SSF (IP multimedia-Service Switching Function) node.

IM-SSF is a kind of AS in the IMS territory, the IMS network provides IM value-added service by various AS for the user in IMS territory, AS mainly comprises: three types of SIP AS, OSA AS and IM-SSF, wherein: IM-SSF provides mapping and the SSP of IMS SIP to circuit domain CAP to trigger ability, makes the seamless succession circuit domain IN service of IMS territory VoIP service-user energy.

The professional presentation mode in IMS territory and IM-SSF interface are as shown in Figure 5.

In Fig. 5, IM-SSF supports three interfaces, wherein, and CAMEL Service Environment be between gsmSCF the CAP interface and and S-CSCF between ISC interface, make gsmSCF can be according to the intelligent service logic on it by IM-SSF to carrying out control corresponding through the IP multimedia session of S-CSCF; Based on the Si interface of MAP, this interface is used for downloading and upgrading from HSS user's CSMEL subscription data between IM-SSF and the HSS.

IM-SSF utilizes CSI (CAMEL Subscription Information) to the gsmSCF trigger intelligent business, and CSI comprises: be applied to the O-IM-CSI of session initiation side, the VT-IM-CSI that is applied to the D-IM-CSI in the dial business and is used for the session termination side.

Gsm-SCF is identical to the route controlling mechanism of calling out with the gsmSCF in the CS territory to the route controlling mechanism of session, when determining that as gsm-SCF the called subscriber need continue in the IMS territory route, gsm-SCF issues the Continue operation to IM-SSF, IM-SSF sends INVITE to S-CSCF, still carry original called party information in this message, like this, S-CSCF continues to finish the session control that is routed to the called subscriber in the IMS territory according to called party information, for another example when gsm-SCF determines that the called subscriber need forward in the CS territory route to, gsm-SCF issues the connect operation to IM-SSF, carry an E.164 number that points to MGCF in this connect operation, IM-SSF sends INVITE to S-CSCF, carry the E.164 number of above-mentioned sensing MGCF in this message, like this, S-CSCF will talk about through BGCF according to the E.164 number of this sensing MGCF and route to MGCF, then, MGCF routes to the CS territory with this session, thereby, finished the route control that in the CS territory, routes to the called subscriber at the calling of initiating in the IMS territory.

Among Fig. 4, when the gsmSCF in the CS territory receives the calling of initiating in the CS territory, determine the called subscriber of this calling, to HLR or HSS inquiry called subscriber's routing decision relevant information, as called subscriber's log-on message and related service CAMEL-Subscription-Information etc., and from the gsm-SCF in CS territory, obtain the information of routed path of this calling, be provided with etc. in the routing policy information in CS and IMS territory such as operator's routing policy and user's preference according to the user who stores in its place entity, the information of routed path of the routing decision relevant information that above-mentioned HLR/HSS returns and this calling is determined the routing decision of this called subscriber's correspondence, and according to this routing decision route is carried out in this calling and control, as gsmSCF according to the routing policy information of user in CS territory and IMS territory, the routing decision relevant information determines that this calling need route to the IMS territory, and this calling of the information representation of routed path of this calling not from the IMS territory route come, then route the call to the IMS territory; GsmSCF determines that in routing policy information, the routing decision relevant information in CS territory and IMS territory these calling needs route to the IMS territory according to the user for another example, and this calling of the information representation of routed path route from the IMS territory of this calling is come, then revise the routing policy of this calling, employing should be called out methods such as continuing in the CS territory route route control was carried out in this calling.GsmSCF should store the routing decision information of this calling, in order to the inquiry of gsm-SCF after finally having determined the routing decision of calling out.

When the S-CSCF in the IMS territory receives the session in IMS territory, according to the iFC criterion this session is triggered on the AS, being about to this session is triggered on the IM-SSF, IM-SSF can trigger the CAMLE business according to called subscriber's the gsm-SCF of VT-IM-CSI information in the CS territory, inquire about called subscriber's routing decision relevant information such as user's registration information and related service CAMEL-Subscription-Information etc. to HLR or HSS according to the CSI called subscriber identification information in calling out by the gsm-SCF in the CS territory, and from the gsmSCF in CS territory, obtain the information of routed path of this calling, the routing decision relevant information that gsm-SCF in the CS territory returns according to above-mentioned HLR/HSS, the user who stores in its place entity is provided with etc. and routed path information in the routing policy in CS territory and IMS territory such as operator's routing policy and user's preference, decide user's routing decision, and carry out the route control of session according to this decision-making, simultaneously, gsm-SCF is after finally having determined the routing decision of calling out, should store the routing decision information of this calling, inquiry in order to gsmSCF, the effect of routed path information in route control is identical with foregoing description, is not described in detail at this.

In the method one, because the routing decision point gsmSCF in CS territory and the routing decision point gsm-SCF in the IMS territory close and are made as same entity, promptly in CS territory and IMS territory, has only a routing decision point, make and in two territories, can share same set of routing policy, not only guaranteed sharing of the dynamic data that produced in the route control procedure carried out in the speech business in two territories, as sharing for the virtual roaming number of forcing route assignment, also ensured the complete realization of route control procedure, simultaneously, avoided owing to the circuitous phenomenon of the asynchronous route that causes of routing policy data, and, make operator easier to the Operation and Maintenance of route policy information.

Utilize method one after the gsm-SCF in CS territory carries out routing decision, to route to the IMS territory for session from the IMS territory or the specific implementation process that routes to the CS territory as shown in Figure 6.

Among Fig. 6, receive session signaling Invite at step 6-1, S-CSCF.

To step 6-2, step 6-3, S-CSCF carries out business according to the filter information among the iFC to session to be triggered, and transmits this Invite to AS.

To step 6-4, IM-SSF VT-IM-CSI information, send IDP to gsm-SCF, with trigger intelligent business according to the called subscriber.

To step 6-5, gsm-SCF service logic according to the definition of the service key among the VT-IM-CSI of IM-SSF triggering, optionally carry out information interaction with HLR, inquiry routing decision relevant information, as optionally sending ATI/ATSI inquiry, the inquiry log-on message of called subscriber in the CS territory and the CAMEL-Subscription-Information of related service to HLR.

To step 6-6, gsm-SCF service logic according to the definition of the service key among the VT-IM-CSI of IM-SSF triggering, optionally carry out information interaction with HSS, inquiry routing decision relevant information, as optionally sending ATI/ATSI inquiry, the inquiry log-on message of called subscriber in the IMS territory and the CAMEL-Subscription-Information of related service to HSS.

Step 6-5 and step 6-6 do not have processing sequence successively.

According to log-on message, the CAMEL-Subscription-Information of related service and the routing policy information of himself storage of the called subscriber who obtains in CS territory and IMS territory, determine the current routing decision of this session to step 6-7, gsm-SCF.

Issue Continue operation according to routing decision to IM-SSF to step 6-8, gsm-SCF, indicate this session to continue route in the IMS territory, or issuing Connect to IM-SSF operates, and carries an E.164 number that points to MGCF, indicates this session to CS territory route.

Send Invite message according to its routing decision that receives to S-CSCF to step 6-9, IM-SSF, if this session need continue route in the IMS territory, then still carry original called address information among the Invite, be original Req-URI information, like this, S-CSCF can route to called subscriber's P-CSCF with this session according to the domain name of Req-URI, thus in the IMS territory with this conversation switching to the called subscriber; If this session need be in the CS territory route, then carry an amended called address information among the Invite, as an E.164 number that points to MGCF, S-CSCF routes to MGCF with this session through BGCF according to the E.164 number of this sensing MGCF, then, by MGCF this session is routed to the CS territory.

According to the Invite that IM-SSF initiates route is carried out in this session to step 6-10, S-CSCF, at this moment, this session is proceeded in the CS territory or in the IMS territory to handle.

In above-mentioned steps 6-7, route for fear of speech business is circuitous, the route circulating phenomenon, gsm-SCF is according to the log-on message of called subscriber in CS territory and IMS territory, the routing policy information of the CAMEL-Subscription-Information of related service and himself storage, when determining this session and need route to the CS territory, gsm-SCF can judge further also whether gsmSCF carried out route control to current sessions, be gsm-SCF obtains speech business from gsmSCF the information of routed path, if the information of routed path of this speech business shows that this session routes to the IMS territory from the CS territory, at this moment, gsm-SCF should not go back to its route to the CS territory again, gsm-SCF can take other route control methods to this session, as revising routing decision this session is continued in the IMS territory route etc.
