Abstract
The invention discloses a method for controlling a local transfer in an IP multimedia sub-system, comprising that when a UE roams in a visit network, an IP address of the visit network is distributed according to the digital gateway of the visit network; when the UE initiates a call, the two IP addresses are added in a calling request message as the addresses which can be sent to a media and a flag which supports a local transfer function is added in the calling request; a P-CSCF determines whether the UE uses the local transfer function and selects an IP address in the calling request as the address of a usable media route; a media connection is established between a called subscriber and the usable media IP address and is replied to the UE which takes the usable IP address which is selected by the network as the address of sending media and establishes a media connection with the called subscriber. The invention can lead the network to have the capability to judge whether the subscriber can use the local transfer function, thus leading the terminal to support the local transfer function when roaming.
Description
Technical field
The present invention relates to communication field, relate in particular to a kind of method that control this locality is produced in IP Multimedia System.
Background technology
IMS (IP Multimedia Subsystem, IP Multimedia System) is third generation affiliate tissue (3rd Generation Partnership Project, abbreviation 3GPP) standard of the next generation network of definition, its distinguishing feature is to have adopted Session initiation Protocol (Session Initiation Protocol, be called for short SIP) system, communication is irrelevant with access, can possess multiple media business controlled function separates with bearing capacity, calling separates with session, application separates with service, business and network detach, and multiple abilities such as mobile network and internet integrated services, the trend of communication network fusion development has been complied with in the proposition of IMS.
Major function entity in the IMS system comprises: the user is provided registration management, the call conversation control function entity of functions such as session control (Call Session Control Function, be called for short CSCF), home subscriber server (the Home Subscriber Server of centralized management user contracting data function is provided, be called for short HSS), application server (the Application Server of miscellaneous service logic control function is provided, be called for short AS), policy control and charging regulation function entity (Policy and Charging RulesFunction is called for short PCRF) are provided.
When the IMS network of user from the IMS netsurfing of ownership place to other, according to prior art, because user's IP address belongs to home network, will occur when this customer call coexist the visit territory the user time, medium need return home domain from visit territory elder generation route, pay a return visit the circuitous phenomenon of visiting network from the home domain route again, as shown in Figure 1.Fig. 1 is the Media Stream schematic diagram that the user calls out visit ground user in the prior art on visit ground, relate generally to following network element and equipment: user terminal 1 (User Equipment 1, be called for short UE1), gateway (Serving Gateway, be called for short SGW), user terminal 2 (UserEquipment 2, are called for short UE2), public data network gateway (Public Data Networks Gateway is called for short PGW).UE1 contracts at the home network of oneself, when UE1 roams into visited network when calling out the user UE2 of the visited network that coexists, after the connection, medium will be from UE1, path 105 between UE1 and SGW, path 106 between SGW and the 105PGW, path 107 between PWG and the UE2 arrives UE2, the path between SGW and the PGW 106 in most of the cases, path 107 between PGW and the UE2 all is distant path, route is circuitous serious, cause a large amount of waste of network resources, while also may be for the user brings huge telephone expenses, in like manner owing to charging policy, when visited network receives calls, also there is identical detour problem.And behind the medium arrival SGW,, will can solve the network weaving problem if directly be routed to UE2 through the path 108 between SGW and the UE2.
3GPP organizes also and is being devoted to solve medium detour problem under the roaming state at present, and the solution of two IP address has been proposed: allow at ability of user terminal, the carrier policy permission, and the condition of network condition permission, can have simultaneously respectively by ownership place operator IP address allocated, this paper claims that this address is H-IP (perhaps being called Home IP, ownership place IP); And by visit ground operator IP address allocated, this paper claims that this address is V-IP (perhaps becoming Visited IP, visit ground IP).
Fig. 2 is the configuration diagram of two IP addresses solution, relate generally to following network element and equipment: user terminal (User Equipment, be called for short UE), gateway (Serving Gateway, be called for short SGW), visit territory public data network gateway (Visited PDN Gateway, be called for short V-PGW), control of visit domain policy and charging rule functions (Visited Policy Control and Charging RulesFunction, be called for short V-PCRF), home domain public data network gateway (Home PDN Gateway, be called for short H-PGW), home domain policy control and charging rule functions (Home Policy Control andCharging Rules Function is called for short H-PCRF), Proxy Call Session Control Function (Proxy CallSession Control Function, be called for short P-CSCF), service call conversation control function (ServingCall Session Control Function is called for short S-CSCF), application server (Application Server is called for short AS).
The part of describing the signaling content is arranged in a request message, use Session Initiation Protocol, describe the part of media content in addition, use SDP (Session Description Protocol, Session Description Protocol).Its main thought is: this address of H-IP can be write on the SIP part, be used for sending signaling.The SDP part is write in the V-IP address, be used for sending medium.Signaling will mail to home network by the path between SGW and the H-PGW 210 through after the SGW, and medium directly mail to the PGW (V-PGW) of visited network through after the SGW by the path between SGW and the V-PGW 211.Because it is less relatively that signaling takies Internet resources, the circuitous of signaling can't cause the very big waste of Internet resources, and the Internet resources that medium occupy are bigger, this framework has avoided the route of medium circuitous, a large amount of Internet resources have been saved, this routing mode of medium, 3GPP are referred to as this locality and produce (Local breakout).
But have such problem for the solution of Fig. 2: the medium that the user wants to send at visited network may not be supported in visited network.At this moment the user just can not use this locality to produce function, and is to use old process shown in Figure 1, promptly needs the medium route is returned the genus network, again media information is sent to the called subscriber by home network.All support this locality to produce under the situation of function so work as user and network, whether the request that network also needs to judge the user can use this locality to produce the mechanism of function.
UE may further comprise the steps in the flow process of IMS network-originated call as shown in Figure 3 in the prior art:
Step 301, calling UE will rise to call for asks (INVITE request) by the P-CSCF that the H-PGW of home domain sends to home domain, comprising a SDP content, describes the media information of calling out;
Step 302, P-CSCF received call for ask after, according to local policy the SDP in the request is judged, if medium meet the requirements, just this request is transmitted the S-CSCF of the distribution of calling UE most;
In this step, if medium are undesirable, P-CSCF returns 488 responses and gives UE, and subsequent step is no longer carried out in the refusal call request;
Step 303, S-CSCF carries out business control;
Step 304, S-CSCF is forwarded to the called subscriber with call request;
Step 305, the called subscriber returns response, comprising called subscriber's media capability;
Step 306, S-CSCF is forwarded to P-CSCF with response;
Step 307, P-CSCF authorizes resource;
Step 308, P-CSCF is forwarded to calling UE with response;
Step 309, calling UE is determined the type of medium according to the other side's response, and answer is made in response;
Step 310 can begin to carry out the reservation of resource after medium type is determined;
Step 311, the answer that P-CSCF will respond is transmitted to S-CSCF;
Step 312, the answer that S-CSCF will respond is forwarded to the called subscriber;
Step 313～315, the called subscriber confirms the answer of calling UE;
Step 316～318, after the Calling Side resource reservation is finished, calling UE will be reserved successful message and issue the called subscriber;
Step 319～321, after the callee side resource reservation was finished, the called subscriber sent to calling UE and reserves successful message;
Step 322～324, the called subscriber returns ring to calling UE;
Step 325, calling UE are heard called subscriber's ring;
Step 326～328, the called subscriber sends the 200OK response request;
Step 329, the beginning media dialog.
In the prior art, network side can not judge whether UE can use this locality to produce function, does not know also whether UE has used this locality to produce function simultaneously, so can't use the solution of two IP addresses to make terminal use this locality to produce function when roaming effectively.
