Description
Technical field
The present invention relates to the IP Multimedia System of the communications field, relate in particular to a kind of method that business configuration is downloaded of in IP Multimedia System, optimizing.
Background technology
IP Multimedia System (IMS, IP Multimedia Core Network Subsystem), adopt the thought of control and 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 (ServingCall 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-CSCF, HSS and application server (Application Server, AS).
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 standard or norm (InitialFilter Criteria, iFC).
Professional trigger condition represents that by initial filter standard or norm according to the difference of user's signing service, can contain many initial filter standard or norms in a user's the business configuration, these initial filter standard or norms all have priority separately.S-CSCF assesses register requirement and conversation initial request according to these initial filter standard or norms, 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 standard or norm 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 standard or norm.
Usually, each terminal use can have one or more business configuration, comprise many initial filter standard or norms (iFC) in each business configuration again, these initial filter standard or norms 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, data volume is big.Especially when customer volume is big, will directly have influence on the transmission performance of HSS and S-CSCF business configuration data download interface, and consume the memory space of HSS and S-CSCF, cause power system capacity or performance decrease.
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 standard or norm.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 initial filter standard or norm collection (Shared iFC Set is hereinafter referred to as sharing the iFC collection) " in business configuration, optimize the download and the storage of business configuration data.
Share the iFC collection and can share use for a plurality of business configuration, each shared iFC collection comprises one or more initial filter standard or norms, be kept at respectively in the local data base of HSS and S-CSCF,, use shared iFC set identifier to carry out unique expression by HSS and S-CSCF maintenance management respectively.
If HSS and S-CSCF support to share the function of iFC collection, so as S-CSCF during from HSS downloading service configuration data, can download by predefined unique shared iFC sign recessively and share the iFC collection, 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.
But there is defective in the definition of sharing the iFC collection at present among the 3GPP, has directly influenced the application of shared iFC collection, makes a concrete analysis of as follows:
(A), we know from the argumentation of front, each initial filter criteria in customer service configuration all has priority, i.e. the order of its coupling, its priority orders except with business mutually outside the Pass, also and the user specifically contract relevant.
For example, a user contracted supplementary service, convention business, messaging service, wherein the priority of messaging service is 3, supplementary service and messaging service and the another one user has only contracted, this moment, the priority of messaging service was 2, perhaps it has also signed this three business, but its order may be different with first user.Therefore can see that in the business configuration of different user, though the configuration rule of initial filter standard or norm is identical, priority might be different.
(B), share each concentrated criterion of iFC its priority is all arranged, and be when the iFC collection is shared in definition, the priority of each iFC has just been determined in the set, if a user need adjust the priority of sharing certain concentrated initial filter standard or norm of iFC, so just may have influence on the use of other users to this shared iFC collection.
For example, comprise 3 independently iFC (being respectively iFC1, iFC2, iFC3) and shared iFC collection in certain user's the business configuration, wherein, comprise 3 independently iFC11, iFC12, iFC13 in this shared iFC collection, corresponding priorities is defined as 5,6,8 respectively by system.
Suppose that initial iFC prioritization is iFC1 (1: represent priority), iFC2 (2), iFC3 (3), iFC11 (5), iFC12 (6), iFC13 (8), when the generation business change, in the time of need before iFC11, increasing two iFC newly, or will in iFC11, iFC12, increase an iFC time, all need to readjust the priority level initializing of sharing the iFC collection, at this moment may other users' configuration be impacted, maybe should share the needs that the iFC collection can't satisfy this user, need redefine new shared iFC collection, maybe need to use additive method to solve the problems referred to above.
Therefore, owing to the difference of different customer service configuration needs, the increase of new business, professional reasons such as adjustment, may cause sharing the iFC collection and can't satisfy service needed, or cause shared iFC collection difficult in maintenance.And this setup needs the network management personnel to understand the configuring condition of interior details, the especially priority of sharing the iFC collection, has increased maintenance difficulties.
In sum, there is defective in the definition of sharing the iFC collection at present, has influenced the application and the effect of shared iFC collection.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method of IP Multimedia System business configuration download, in order in the business configuration downloading process of IP Multimedia System, overcome the existing defective that the iFC collection exists of sharing, realization is to the optimization of customer service configuration data downloading process, both can be applied to the optimization that the business configuration data are downloaded, can also be applied to the storage and the processing of configuration data simultaneously.

(g) after S-CSCF receives Notification of Changes, if comprise independent shared iFC sign and corresponding priority level in the discovery business configuration, then from local data base, search and obtain this and identify pairing iFC data, and the priority that this criterion is set is download business configuration medium priority, the renewal customer service disposes, and returns the download successful respond to HSS.
(h) receive initial session when setting up request as S-CSCF, utilize step (d), (e) or (f), the business configuration obtained in (g) handles conversation request by normal processes.
In the described method, IP Multimedia System should be compatible mutually with the IMS standard of 3GPP definition.
In step of described method (d) and the step (f):
If HSS and S-CSCF support independent shared iFC feature, HSS downloads iFC by unique independent shared iFC sign to S-CSCF recessively, S-CSCF obtains iFC according to independent shared iFC sign from local data base, and determines the priority of iFC according to the priority parameters that download is come;
If S-CSCF does not support this feature, HSS can not download independent shared iFC to S-CSCF, but utilize the HSS local data base that independent shared iFC sign is mapped as iFC, and determine the priority of iFC according to the priority parameters among the independent shared iFC after, download again and give S-CSCF;
If HSS does not support this feature, S-CSCF there is not specific demand, it can support or not support independent shared iFC.
Know by the dynamic discovery mechanism of the supported feature of Cx interface whether the other side supports to share the iFC feature between described HSS and the S-CSCF, and make correct processing according to the information that gets access to.
This independent shared iFC only is applied to application server request for allocation/server acknowledge order between HSS and the S-CSCF at present to push request/configuration propelling movement acknowledgement command right with configuration, is not applied to other and orders right occasion but do not get rid of.
Method described in the invention can be applied to other configuration download interface of IP Multimedia System, triggers logic as application server from HSS down load application business platform.Safeguard the consistency of independent shared iFC in HSS and the S-CSCF local data base by operator, its maintenance strategy can be consistent with the mode of shared iFC collection.
In the described method, HSS and S-CSCF can utilize mechanism storage service configuration data in local data base of independent shared iFC, reach the purpose of saving the business configuration data space.
Shown in Figure 2 is the professional embodiment that triggers in the call establishment, in order to the application of optimization method under many initial filter standard or norm situations that illustrates that business configuration of the present invention is downloaded.S-CSCF can be by three kinds of modes from HSS trigger for download criterion
1) complete information of download initial filter standard or norm;
2) download shared iFC set identifier, S-CSCF utilizes this sign to obtain the complete information that shared iFC concentrates included initial filter standard or norm from local data base;
3) download independent shared iFC sign and priority, S-CSCF utilizes this only sign to obtain the information of initial filter standard or norm except that priority from local data base, and the priority of this initial filter standard or norm is set, thereby obtain the complete information of initial filter standard or norm according to the priority of downloading.
Above-mentioned three kinds of modes can and be deposited in same downloading process, the priority unified planning of different filter criteria.
Suppose that this user has two filter criteria X, Y (can be downloaded from HSS by above-mentioned three kinds of modes by S-CSCF), wherein, the priority ratio Y height of X, so, trigger flow process and may further comprise the steps:
Step 201, the user starts a SIP session by sending a SIP initial call request to its S-CSCF 210.
Step 202, after receiving this initial call request, S-CSCF checks whether session foundation request mates with filter criteria X, if coupling, then S-CSCF forwards the request to application server 1 (212).In trigger process, Service Point Trigger comprises trigger condition and triggers the result, and trigger condition is the feature of extracting from trigger request, as message name, called subscriber etc., triggers the result and be when condition satisfies the destination with forwards.
Step 203 after application server 1 executes specific service logic, is asked loopback again to give S-CSCF this SIP, and may be revised service related information.
Step 205 after application server 2 executes specific service logic, is asked loopback again to give S-CSCF this SIP, and may be revised service related information; Otherwise execution in step 206.
Step 206, if this SIP request does not all match with any follow-up filter criteria, then S-CSCF seeks next jumping according to normal SIP routing mechanism and transmits then.
Shown in Figure 3 is the embodiment of S-CSCF downloading service configuration in the endpoint registration process, and S-CSCF in user's not registered state download user business configuration similarly.Reciprocal process may further comprise the steps:
Step 301, terminal sends register requirement to visited network P-CSCF (Proxy Call Session Control Function, Proxy Call Session Control Function).
Step 302, P-CSCF sends this register requirement to the I-CSCF of user attaching network (Interrogate Call SessionControl Function, query call conversation control function).
Step 303, I-CSCF sends S-CSCF (ServingCall Session Control Function) to HSS (Home Subscriber Server) and distributes query requests.
Step 304, HSS returns the S-CSCF assignment response to I-CSCF, is the S-CSCF of user's appointment, or comprises the ability of a plurality of optional S-CSCF, selects S-CSCF by I-CSCF according to the customer service demand.
Step 305, I-CSCF to appointment or transmit register requirement according to the selected S-CSCF of professional ability.
Step 306, S-CSCF includes public identify, privately owned sign, S-CSCF name to the request that HSS sends the download user configuration data in this request message.
Step 307, HSS is to S-CSCF download user business configuration data, comprising initial filter standard or norm, shared iFC set identifier, independent shared iFC sign and priority parameters, wherein:
If HSS and S-CSCF support to share iFC collection feature, wherein might comprise and share the iFC sign;
If HSS and S-CSCF support the independent shared iFC feature that the present invention defines, wherein might comprise independent shared iFC sign and corresponding priority level thereof;
If S-CSCF does not support to share iFC collection feature, HSS need will share the iFC set identifier according to local data base and be converted to initial filter standard or norm, and the priority of this initial filter standard or norm iFC is set according to the priority in the configuration;
If S-CSCF does not support independent shared iFC feature, HSS need be converted to initial filter standard or norm according to local data base with independent shared iFC sign, the priority that the priority of initial filter standard or norm is determined for independent shared iFC.
Step 308, S-CSCF utilizes the information of downloading from HSS that contains initial filter standard or norm, shared iFC set identifier, independent shared iFC sign, constitutes user's triggering criterion jointly.If comprise in the download business configuration and share the iFC set identifier, S-CSCF obtains this shared set institute to deserved iFC from local data base;
If comprise independent shared iFC sign and corresponding priority level in the download business configuration, S-CSCF obtains from local data base and does not contain priority or priority is empty iFC, and determines the priority of iFC according to the priority parameters that download is come;
Step 309, S-CSCF returns the message that succeeds in registration to I-CSCF.
Step 310, I-CSCF returns the message that succeeds in registration to P-CSCF.
Step 311, P-CSCF returns the message that succeeds in registration to terminal.
