Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of method for processing PRI conflict of initial filtrating rules.
Background technology
IP Multimedia System (IP Multimedia Core Network Subsystem, be called for short IMS), adopt the thought of controlling with service detach, it is professional that the IMS key-course does not provide, only provide the function such as triggering, route, charging of operation layer necessity, and business is provided by operation layer fully.
The professional triggering is the critical function of IMS key-course, is that the S-CSCF (Serving Call Session Control Function, service call controlled function) by the IMS key-course finishes.User's professional trigger data is represented with " business configuration (Service Profiles) ", and is kept among the HSS (Home Subscriber Server, home subscriber server) as the part of user's configuration (User Profiles) data.As shown in Figure 1, it is the professional frame diagram that triggers in the IP Multimedia System, show the professional built-in function that triggers related network element, interface and each network element, wherein mainly comprise S-CSCF102, HSS104 and application server (Application Server, AS) 106.
When the user registers, or S-CSCF receives when exhale the initial request of session an end of non-registered users, or S-CSCF receives when a server generation works the initial request of exhaling session for Client-initiated, the business configuration data are downloaded to the S-CSCF from HSS, comprising initial filter criteria (Initial Filter Criteria, IFC).
Professional trigger condition is represented by initial filter criteria, difference according to user's signing service, can contain many initial filter criteria in a user's the business configuration, these initial filter criteria all have priority separately, and the priority of the initial filter criteria in same business configuration does not repeat.S-CSCF assesses register requirement and conversation initial request according to these initial filter criteria, and according to assessment result these requests is sent to the application server (AS) of appointment, provides corresponding service by these application servers according to request.
In Fig. 2, the example of the trigger process of a call request has been described, wherein, the user has disposed two initial filter criteria X, Y, S-CSCF mates call request in order with each criterion, by the mode controlling call path of triggering, and provide professional by application server.The order that triggers directly has influence on professional execution, and in IMS, professional trigger sequence is to represent by the priority of initial filter criteria.
In the 3GPP definition, initial filter criteria is included in the business configuration, and business configuration belongs to the part of customer service configuration data.Fig. 3 a, 3b, 3c are UML (standard modeling language, the Unified Modeling Language) models of customer service configuration data, use the mode of UML to describe user configured structure and information.
Shown in Fig. 3 a, define according to 3GPP, the user disposes class 302 and comprises a private user identity parameter of describing with network access identifier (NAI, Network Access Identifier) mode, and the example that each user disposes class comprises one or more business configuration 304 examples.
Fig. 3 b is the uml model of business configuration, and wherein square frame 306 internal representations is the part of 3GPP definition business configuration class.Each example of business configuration class 304 comprises the example of one or more public identifier classes 308, comprises common user or service identification in the public identifier class.Core net service authentication 310, initial filter criteria 312, share I FC collection 314 can be applied to all public identifiers of comprising in the business configuration class.In the standard definition of 3GPP, a share I FC collection can be applied to a plurality of business configuration.
Fig. 3 c is the uml model of initial filter criteria (IFC), and IFC typically comprises a priority (integer), a configuration section designator (enumeration type), a trigger point 316 and an Application Server information 318 at the most.Wherein, Application Server information is made up of server name and other information of expressing with SIP URL form.
Usually, each terminal use can have one or more business configuration, comprises many initial filter criteria (IFC) in each business configuration again, and these initial filter criteria can be regarded some logical expressions as, the professional condition that triggers of expression and the destination of triggering, and use text mode to describe.
Consider in actual applications, the signatory identical business of a lot of users, supplementary services such as the caller identification of all opening basically such as mobile network's user, calling transfer, promptly these customer services are all used same or analogous initial filter criteria.Some business in addition, as present business, need many IFC to be triggered to a plurality of application servers in certain sequence and just can finish this business.Therefore, 3GPP has introduced the notion of " sharing inceptive filtering rule set (Shared IFC Set is hereinafter referred to as share I FC collection) " in business configuration, optimize the download and the storage of business configuration data.
Share I FC collection can be shared for a plurality of business configuration and use, each share I FC collection comprises one or more initial filter criteria, be kept at respectively in the local data base of HSS and S-CSCF,, use share I FC set identifier to carry out unique expression by HSS and S-CSCF maintenance management respectively.
If HSS and S-CSCF support the function of share I FC collection, so as S-CSCF during from HSS downloading service configuration data, can download share I FC collection by predefined unique share I FC set identifier recessively, or not concrete IFC when promptly downloading, but from the S-CSCF local data base, search and obtain corresponding IFC set by this sign that S-CSCF obtains by download, thereby can significantly reduce the data traffic of download interface, and and then can reduce taking of HSS/S-CSCF memory space, the capacity and the performance of raising system.
As previously mentioned, finishing of a business may relate to several IFC, triggers corresponding server in a certain order and finishes its function jointly.In existing 3GPP standard, the trigger sequence of IFC is to control by the priority of IFC.Priority is the order of its coupling, its priority orders except with business mutually outside the Pass, also and the user specifically contract relevant.
A business configuration may comprise several independent IFC, several share I FC collection.According to the definition of 3GPP for share I FC, share I FC set pair all IFC in set do not redefine its priority, but have continued to use the original priority of each IFC.
The explanation that more than provides has hinted some result, promptly according to the technical specification of 3GPP, should require at least in a business configuration, must assurance no matter be IFC independently, still be positioned at the IFC that share I FC concentrates, its priority must guarantee in this business configuration, to be in can be controlled state, need promptly to guarantee that its priority of priority is unlikely to occur conflict in this scope.
Yet, in the existing mechanism, because the introducing of share I FC collection makes the possibility that the IFC PRI conflict occurs increase greatly.According to the feature of share I FC collection, the IFC that it comprised is not limited to certain business configuration, and share I FC collection can use by several business configuration, has caused may causing in same business configuration the conflict of IFC priority.Typically, a business configuration as described in Figure 4, four independent IFC, two share I FC collection have been comprised, because not corresponding the inspection and tied mechanism in configuration, cause the PRI conflict that IFC5 and independent IFC2 are arranged in the share I FC collection 1, the PRI conflict of the IFC6 in IFC7 and the share I FC collection 1 is arranged in the share I FC collection 2.
In addition, the change for the priority of certain IFC may have influence on share I FC collection or business configuration that all comprise this IFC, may cause PRI conflict because of change priority.In sum, in the 3GPP standard, to the treatment mechanism defectiveness of IFC priority, be issued to the IFC of S-CSCF or AS at present, may have PRI conflict, PRI conflict causes the professional confusion of carrying out possibly further.
Summary of the invention
One or more problems in view of the above, the present invention proposes a kind of method for processing PRI conflict of initial filtrating rules, can solve in issuing the process of initial filter criteria, dynamically adjust the PRI conflict in the initial filter criteria, the professional confusion of avoiding PRI conflict to bring.
