Description
Technical field
The present invention relates to the 3G (Third Generation) Moblie technology, relate in particular to the method for download interface data in IP Multimedia System (IMS, IP Multimedia Subsystem).
Background technology
In order to satisfy the needs of multimedia communication, 3GPP is organized on the basis of original packet carrying network and has introduced IP Multimedia System (IMS, IP Multimedia Subsystem), IMS can not only provide traditional voice service to the user, also can provide abundant multimedia service to the user.IMS comprises home subscriber server (HSS, Home Subscriber Server), application server (AS, Application Server), service call controlled entity (Serving-Call Session Control Function, S-CSCF), query call controlled entity (Interrogating-Call Session Control Function, I-CSCF), the agent call controlled entity (Proxy-Call Session Control Function, P-CSCF).The agent call controlled entity can be in the Access Network of the current location of user, insert first contact network element of IMS network as the user, (Session Initiation Protocol, SIP) call signaling is forwarded to the IMS core net user's initial session protocol.The query call controlled entity is used for hiding network internal information, realizes network security.The service call controlled entity is finished basic CCF as the controlling call entity of core, and the interface with application server is provided.Application server is used for providing miscellaneous service to the user, such as basic voice, video traffic and supplementary service.Interface between service call controlled entity and home subscriber server is called Cx interface.Interface between application server and home subscriber server is called Sh interface.
Home subscriber server is the network element of storaging user data in the IMS network, in store all with the signatory relevant information of user, be used to support each network element to calling out and professional processing.When the user was registered to network, the partial data that the user contracts can download to the service call controlled entity by Cx interface, also had certain customers' data to download to application server by Sh interface.Application server by with the Sh interface of home subscriber server, obtain customer service related data and user state information, the Business Processing when calling out to carry out.
In the IMS network, the user uses public user identity, and (Public User Identity PUI) calls out and service contracting, uses private user identity (Private User Identity, the authentication when PVI) registering.The user carries private user identity and public user identity in registration message, S-CSCF uses private user identity to carry out authentication to home subscriber server, download the pairing subscription data of public user identity (Service Profile) from home subscriber server simultaneously, can contain many initial filter criteria (Initial Filter Critic in every part of subscription data, IFC), include matching condition in every initial filter criteria, priority, information such as the title of application server, the initial filter criteria that has uses when calling out, and the initial filter criteria that has uses when registration.
Figure 1 shows that the initial filter criteria data model of stipulating in Cx interface and the Sh interface standard.The above-mentioned matching condition of mentioning promptly be meant trigger point among Fig. 1 (Trigger Point, TP) with Service Point Trigger (Service Point Trigger, SPT).Can specify the application server title in the application server element among Fig. 1.Can contain multiple coupling factor in the Service Point Trigger, and be combined into expression formula, be combined into unified matching condition expression formula by the ConditionTypeCNF in the trigger point.
The purpose of using initial filter criteria is to provide professional application server for being defined as the user.In the network operation of reality, many users' service feature is similar, provide by same application server, thereby these users' initial filter criteria data will be identical.
The Cx interface data are to be described by the XML text formatting, and data volume is bigger.In order to improve the data download performance of Cx interface, 3GPP is organized in and has introduced share I FC collection (Shared IFC Set) in the Cx interface.Share I FC collection comprises one or more IFC, is kept at simultaneously on HSS and the S-CSCF, and each share I FC collection all has independent sign, contains Service Point Trigger and AS information, and the priority of IFC among each IFC.
Sign, the content of the share I FC collection on HSS and the S-CSCF are identical fully.Thereby, if certain user's IFC set is identical with certain share I FC set content, just need in user's Cx interface data, not provide the IFC data separately, only need provide share I FC the identification number of collection.S-CSCF can obtain user's Cx interface data from Cx interface, obtains the identification number of share I FC collection again from the Cx interface data, and then obtains corresponding IFC set in this locality, as this user's IFC collective data.Thereby making does not need to comprise the IFC collective data in many users' the Cx interface data, only need represent the sign of share I FC collection with the form of integer, just can reduce the data traffic of Cx interface, and the performance of raising Cx interface.The data of Sh interface are described with the XML text formatting equally, though also contain IFC in the user data of Sh interface, do not introduce share I FC collection, even there are a plurality of users to have identical IFC, also can't reduce the data volume flow of Sh interface.
Though 3GPP is organized in the data traffic that the share I FC collection of introducing in the Cx interface has reduced Cx interface to a certain extent.But along with the network operation time is more and more longer, the user is more and more, and business demand also becomes increasingly complex, and the share I FC collection that the 3GPP tissue is introduced just can't satisfy the demands.For example, some customer requirements uses convention business, and for these users, the share I FC collection that just needs to provide new in its Cx interface data is to specify the AS of convention business.But the user who has requires not use convention business again, will remove the share I FC collection of the AS that specifies convention business so from the Cx interface data.
Thereby, because the increasing difference of user on business demand perhaps increased business newly in the network, original share I FC collection can not be satisfied the demand, need to increase or deletion share I FC collection.If the share I FC collection in the network significantly increases, will be unfavorable for the maintenance of share I FC collection and Cx interface data.
In a word, the share I FC collection underaction of existing C x interface, the business demand of encompasses users that can only be substantially, and be difficult to safeguard that deletion share I FC collection then can increase the Cx interface data traffic again.Simultaneously, Sh interface is not introduced share I FC collection, makes that the data traffic of Sh interface is bigger.
