Description

The priority processing method of initial filter criteria

Technical field

The present invention relates to the communications field, relate in particular to a kind of priority processing method of initial filter criteria.

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; Functions such as the necessary triggering of operation layer, route, charging only are provided, and business is provided by operation layer fully.

Service trigger 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 accomplishes.User's service trigger data are represented with " business configuration (Service Profiles) ", and are 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 frame diagram of service trigger in the IP Multimedia System; Show the built-in function of the related network element of service trigger, 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 by being downloaded to the S-CSCF from HSS, comprising initial filter criteria (Initial Filter Criteria, IFC).

Professional trigger condition is represented through 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, according to request corresponding service is provided by these application servers.

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 matees call request in order with each criterion, through 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 through 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; User's type of configuration 302 comprises a private user identity parameter of describing with network access identifier (NAI, Network Access Identifier) mode, and the instance of each user's type of configuration comprises one or more business configuration 304 instances.

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 instance of business configuration class 304 comprises the instance of one or more public identifier classes 306, 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 with other information a server name of expressing with SIP URL form.

Usually; Each terminal use can have one or more business configuration; Comprise many initial filter criteria (IFC) in each business configuration again, these initial filter criteria can be regarded some logical expressions as, the condition of expression service trigger 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 practical application, 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, needing many IFC to be triggered in certain sequence that a plurality of application servers could accomplish should business.Therefore, 3GPP has introduced the notion of " sharing inceptive filtering rule set (Shared IFC Set below is called 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 through 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, thereby can significantly reduce the data traffic of download interface by this sign that S-CSCF obtains through download; And and then can reduce taking of HSS/S-CSCF memory space, the capacity and the performance of raising system.

As previously mentioned, the completion of a business possibly relate to several IFC, triggers corresponding server in a certain order and comes common its function of accomplishing.In existing 3GPP standard, the trigger sequence of IFC is to control through the priority of IFC.Priority is the order of its coupling, its priority orders except with business mutually outside the Pass, also relevant with specifically contracting of user.

A business configuration possibly 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 define its priority again, 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; Upon request 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 guarantee that promptly 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 characteristic 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 in same business configuration, may causing the conflict of IFC priority.Typically; Like the described business configuration of Fig. 4; Four independent IFC, two share I FC collection have been comprised; Because not corresponding inspection and tied mechanism cause the PRI conflict that IFC5 and independent IFC2 are arranged in the share I FC collection 1 in configuration, and 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, at present in the 3GPP standard,,, there is not corresponding checking mechanism for processes such as the providing of IFC priority, changes to the treatment mechanism defectiveness of IFC priority.

Summary of the invention

One or more problems in view of the above; The present invention proposes a kind of priority processing method of initial filter criteria; Can solve and create initial filter criteria, creating the implicit PRI conflict problem in the processes such as sharing inceptive filtering rule set, change initial filter criteria priority; Can overcome the defective that existing IFC priority mechanism exists, eliminate professional chaotic that PRI conflict brings.

Processing method according to the priority of IFC in the IMS of the present invention system may further comprise the steps:

Step S502 increases IFC priority dynamic index table, in order to judge whether to exist the IFC PRI conflict in HSS.The record of priority dynamic index table comprises: the priority sphere of action of IFC, IFC shared set sign, IFC sign, priority.

When step S504, HSS relate to the operation of IFC priority variation in execution, need to judge whether the PRI conflict of inspection IFC.Like need inspections,, search to IFC priority dynamic index table and to have or not and the afoul IFC of this IFC priority then according to set IFC priority sphere of action.

Step S506 exists under the situation of afoul IFC, and the error process flow process under the situation that does not have afoul IFC, is upgraded corresponding record in the IFC priority dynamic index table.

Wherein, need issue user data under the situation of S-CSCF at HSS, carry out following processing: when extracting user data, the priority of the IFC that comprises in the inspection user data has or not conflict at HSS.The IFC that promptly all independent IFC, share I FC is concentrated, inspection has or not PRI conflict.The principle that the system of starting from seamlessly transits can not once all be accomplished in the adjustment the correction of IFC PRI conflict, therefore, when HSS arrives S-CSCF in the download user data, still need carry out simple inspection and conflict correction.HSS is when extracting the data of a business configuration, and with independent IFC, the concentrated IFC of share I FC that inspection wherein comprises, inspection has or not PRI conflict.If any PRI conflict, HSS has the priority of the IFC of conflict according to the simplest enumerative principle correction in proper order.HSS need clearly write down this conflict simultaneously, and the conflict of being write down will be reacted in the Operation & Maintenance System.

S-CSCF upgrades local customer service configuration after receiving Notification of Changes and receiving the customer service configuration of renewal, and returns the download successful respond to HSS.

When S-CSCF receives user's initial session foundation request, utilize the business configuration of obtaining to handle conversation request by normal processes.

Wherein, IFC priority dynamic index table comprises following at least a information: priority sphere of action, priority, IFC identify, reach share I FC set identifier.IFC priority sphere of action can be set to comprise following at least a according to carrier policy: the corresponding initial filter criteria of the initial filter criteria that one or more business configuration that the corresponding initial filter criteria of global scope, user subscribe to are corresponding and business configuration, and other particular forms.

If IFC priority sphere of action is overall; Then mean the strictest IFC priority check; HSS will think all IFC in same priority sphere of action, and no matter which kind of business it is associated with, whether positive connection arranged each other; Also promptly meaning HSS and in global scope, checking priority, guaranteeing can not occur any two IFC and share same priority.

In IFC priority sphere of action is that then HSS will check that same user subscribes to the priority of all interior IFC under the situation of one or more business configuration corresponding processing filtering rules of subscribing to of user.A user subscribes to and possibly comprise several business configuration, and HSS will check that this user subscribes to the priority that interior all users dispose interior IFC.

In IFC priority sphere of action is under the situation of the corresponding initial filter criteria of a business configuration, and then HSS only checks the priority of IFC in a business configuration.

Wherein, The storage of priority sphere of action information is carried out by following mode: when the priority sphere of action is a user when subscribing to, priority sphere of action information must comprise the designator of subscribing to for the user in order to indication priority sphere of action, unique identification marking of this user's subscription.Equally, when priority was a business configuration as scope, priority sphere of action information must comprise that being used to indicate the priority sphere of action is the designator of business configuration, the unique identification of this business configuration.

Wherein, HSS operation that IFC is carried out comprises following at least a: newly-increased IFC, upgrade IFC, newly-increased share I FC collection, adjustment share I FC collection, all relate to the step of IFC priority check to business configuration data configuration share I FC collection etc.

HSS is carrying out at first retrieving IFC priority dynamic index table before the corresponding IFC operation, and retrieval is according to comprising priority sphere of action information and priority.The priority that HSS relies on this priority sphere of action information and IFC to set is removed the search index table, has equal priority if retrieve the IFC of non-IFC, promptly thinks PRI conflict to occur.

After HSS retrieved PRI conflict, HSS need inform clearly that PRI conflict appears in subsequent step, handles according to subsequent process scheme.

HSS comprises to the process that S-CSCF issues user data: S-CSCF notifies user data downloading process such as S-CSCF to HSS request download user data and HSS when user data changes.

Priority sphere of action to IFC is the situation of global scope, and the present invention limits IFC priority through following processing scope is set:

A kind of IFC priority limit qualified list is provided, and this priority limit qualified list limits record some priority limits and constitutes, and each priority limit limits and comprises: type of service sign, the priority upper limit, priority lower limit.Simultaneously, the SIP URL of application service is provided the mapping mechanism to type of service, can knows the type of service of this application service according to the SIP URL of concrete application service.

HSS if judge the variation that operation relates to IFC priority, need check at first whether the setting of IFC priority has exceeded admissible bound when operation IFC.Concrete detection method is: HSS searches the pairing type of service of this SIP URL according to the service name that appears with SIP URL form in the application service information entrained among the IFC.HSS searches the IFC priority bound scope that type of service allows setting according to the type of service of obtaining.HSS checks the priority of the IFC that needs operation according to the priority bound of obtaining, and detects whether exceed restricted portion.

If affirmation needs the priority of the IFC of operation not exceed the scope of permission, then carry out subsequent operation, otherwise the error process flow process.

Wherein, the concrete priority limited range of every kind of business is set according to plan of operation and match condition by operator, and normally, the priority limited range that needs to guarantee the different business classification is unlikely to occur overlapping.

IFC has carried application service information, comprising the service name information that appears with SIP URL form.According to the mapping mechanism of application service to type of service, can confirm the type of service that IFC is affiliated, further can know the admissible priority bound of this IFC scope.

The IFC priority limit limits mechanism, typically is applied to all occasions that relates to the IFC priority change, comprises establishment and the adjustment etc. of adjustment, the share I FC collection of establishment, the IFC of IFC.The priority that the following steps of utilizing HSS the limit IFC behavior of crossing the border:

According to type of service segmentation and the unified arrangement of service trigger order, HSS can provide the IFC priority bound to different service types whether to have overlapping check to the IFC priority bound scope of type of service by operator.

Application service title so that SIP URL form is expressed is deferred to 3GPP related protocol regulation.HSS should be able to detect the multiple business type that whether had the same application service association when the pairing type of service of application service is set.

Simultaneously, the present invention also is devoted to provide a kind of in global scope, being used to limit the method that IFC priority is provided with scope, the problem of crossing the border of having avoided priority to be provided with.

Through the present invention; In IP Multimedia System; To the priority of IFC, be provided with the IFC priority dynamic index table of the overall situation, and corresponding inspection and control method are provided simultaneously; Can solve the PRI conflict problem of IFC from the source effectively, avoid the confusion of service trigger further.

Embodiment

With reference to accompanying drawing, specify embodiment of the present invention below.

Fig. 5 is the flow chart according to the priority processing method of initial filter criteria of the present invention.As shown in Figure 5, the processing method according to the priority of IFC in the IMS of the present invention system may further comprise the steps:

Step S504, HSS need to judge whether the PRI conflict of inspection IFC when carrying out relevant IFC operation.Like need inspections,, search to IFC priority dynamic index table and to have or not and the afoul IFC of this IFC priority then according to set IFC priority sphere of action.

Priority processing method according to the initial filter criteria of the embodiment of the invention comprises:

In HSS, increase IFC priority dynamic index table, be used to write down the priority of each IFC.Institute's information recorded comprises priority sphere of action, IFC shared set sign, IFC sign, the priority of each IFC.The priority sphere of action of IFC can be set to following several kinds according to carrier policy: initial filter criteria, corresponding initial filter criteria, initial filter criteria, other particular forms that business configuration is corresponding of one or more business configuration that the user subscribes to that the overall situation is corresponding.

When creating a new IFC, HSS at first checks IFC priority dynamic index table before registration IFC record.Under identical priority sphere of action, if there be the IFC identical, then return error message, to reset the priority of IFC with this IFC priority.If there is not the IFC of equal priority, then confirm the log-on operation of IFC after, in IFC priority index table, increase the priority index information of this IFC.

When adjusting the priority of an IFC, HSS need at first check IFC priority dynamic index table before adjustment.Under identical priority sphere of action, if there be the IFC identical, then return error message, to reset the priority of this IFC with the new priority of this IFC.If there is not the IFC of equal priority, then confirm the retouching operation of IFC, the priority of revising this IFC in the IFC priority list then is new priority.

When the share I FC collection in business configuration of adjustment; HSS needs to concentrate each IFC to carry out aforesaid PRI conflict checking process to this IFC earlier; Carry out corresponding IFC adjustment again after confirming not have conflict, and according to circumstances revise the priority of corresponding IFC in the IFC priority dynamic index table synchronously.

As S-CSCF during to user data of HSS request, HSS when extracting the data of a business configuration, the independent IFC that inspection is wherein comprised, the IFC that share I FC concentrates, inspection has or not PRI conflict.

The principle that the system of starting from seamlessly transits can not once all be accomplished in the adjustment the correction of IFC PRI conflict, therefore, when HSS arrives S-CSCF in the download user data, still need carry out simple inspection and conflict correction.HSS is when extracting the data of a business configuration, and with independent IFC, the concentrated IFC of share I FC that inspection wherein comprises, inspection has or not PRI conflict.If any PRI conflict, HSS has the priority of the IFC of conflict according to the simplest enumerative principle correction in proper order.HSS need clearly write down this conflict simultaneously, and the conflict of being write down will be reacted in the Operation & Maintenance System.

After S-CSCF receives data, upgrade the local user traffic data, carry out follow-up processing flow.

When change takes place in the customer service configuration data among the HSS; HSS can be initiatively to the S-CSCF download user business configuration data for this user's service; HSS will at first carry out IFC PRI conflict inspection in the business configuration, and checking process is the same, and inspection will be downloaded to S-CSCF through the back data.

After S-CSCF receives Notification of Changes, handle, and return the download successful respond to HSS by normal flow.

When S-CSCF received initial session foundation request, the business configuration of obtaining more than the utilization was handled conversation request by normal processes.

In the said method, IP Multimedia System should be compatible mutually with the IMS standard of 3GPP definition.

The priority sphere of action of IFC can be set to following several kinds according to carrier policy: the overall situation, user subscribes to, business configuration, other particular forms.

Subscribe to if IFC priority sphere of action is a user, then HSS will check that same user subscribes to the priority of all interior IFC.A user subscribes to and possibly comprise several business configuration, and HSS will check that this user subscribes to the priority that interior all users dispose interior IFC.

If IFC priority sphere of action is a business configuration, then HSS only checks the priority of IFC in a business configuration.

In said method, HSS is carrying out at first retrieving IFC priority dynamic index table before the corresponding IFC operation, and retrieval is according to comprising priority sphere of action information and priority.When the priority sphere of action is a user when subscribing to, priority sphere of action information must comprise the designator of subscribing to for the user in order to indication priority sphere of action, unique identification marking of this user's subscription.Equally, when priority was a business configuration as scope, priority sphere of action information must comprise that being used to indicate the priority sphere of action is the designator of business configuration, the unique identification of this business configuration.The priority that HSS relies on this priority sphere of action information and IFC to set is removed the search index table, has equal priority if retrieve the IFC of non-IFC, promptly thinks PRI conflict to occur.

In the said method; Priority sphere of action to IFC is the situation of global scope; Can be according to concrete class of service; IFC is sorted out, and the priority of a certain type of all professional relevant IFC is in the scope of an appointment, and the priority of the IFC that another kind of business is relevant is then in nonoverlapping another is divided into.To this situation, the present invention provides a kind of IFC priority limit to limit mechanism equally, is used for when setting IFC priority according to class of service inspection priority level initializing off-limits apparatus and method whether.

Described IFC priority limit limits mechanism, is made up of IFC priority limit qualified list, application service type of service and concrete checking mechanism.Fig. 6 is the uml model sketch map that IFC priority limit of the present invention limits configuration.As shown in Figure 6, IFC priority limited range configuration 602 comprises several preferential level scopes qualifications 604, several application service types of service 606, several types of service 608.Type of service 608 comprises type of service sign and type of service descriptor, and each application service type of service 606 is made up of a service name and the type of service sign with the SIPURL sign.A concrete priority limit limits and comprises type of service sign, IFC priority higher limit, IFC priority lower limit.

(1) when HSS confirms the priority of an IFC need be set; HSS is according to service name in the Application Server information among the IFC; Utilize the described application service type of service of Fig. 6 to carry out table lookup operation, retrieve the type of service sign of this IFC institute application associated service;

(2) HSS utilizes the described priority limit of Fig. 6 to limit tabulation and carries out table lookup operation according to the type of service of the IFC institute application associated service that is retrieved in (1), retrieve to IFC the priority bound of corresponding type of service;

(3) the IFC priority bound that retrieved according to (2) of HSS is checked the priority of the IFC that needs to be provided with, exceeds said IFC priority bound institute restricted portion like the priority of this IFC, then points out priority to exceed the business configuration scope;

Further, in the said IFC priority limit qualification method:

The said application service title of expressing with SIP URL form is deferred to 3GPP related protocol regulation.HSS should be able to detect the multiple business type that whether had the same application service association when the pairing type of service of application service is set.

According to type of service segmentation and the unified arrangement of service trigger order, HSS can provide the IFC priority bound to different service types whether to have overlapping check to the IFC priority bound scope of said type of service by operator;

With reference to the embodiment of service trigger in the call establishment shown in Figure 2, in order to the application of processing method under many initial filter criteria situation of explaining that business configuration of the present invention is downloaded.S-CSCF can be through dual mode from HSS trigger for download criterion: the complete information of downloading initial filter criteria; And downloading share I FC set identifier, S-CSCF utilizes this sign to obtain the complete information that share I FC concentrates included initial filter criteria from local data base.

Above-mentioned dual mode can and be deposited in same downloading process.

Suppose that this user has two filtering rule X, Y (can be downloaded from HSS through above-mentioned three kinds of modes by S-CSCF), wherein, the priority ratio Y of X is high, so, triggers flow process and may further comprise the steps:

Step S202, the user starts a SIP session through sending a SIP initial call request to its S-CSCF.

Step S204, after receiving this initial call request, whether S-CSCF inspection session is set up asks to mate with filtering rule X, if coupling, then S-CSCF forwards the request to application server 1.In trigger process, Service Point Trigger comprises trigger condition and triggers the result, and trigger condition is the characteristic of from trigger request, extracting, and like message name, called subscriber etc., triggers the result and be when condition satisfies the destination with forwards.

Step S206 after application server 1 executes specific service logic, asks loopback again to give S-CSCF this SIP, and may revise service related information.

Step S208, receive the SIP request of returning from application server 1 after, S-CSCF check once more conversation request whether with filtering rule Y coupling, if coupling, then S-CSCF forwards the request to application server 2; Otherwise execution in step S212.

Step S210 after application server 2 executes specific service logic, asks loopback again to give S-CSCF this SIP, and may revise service related information; Otherwise execution in step S212.

Step S212, if this SIP request does not all match with any follow-up filtering rule, then S-CSCF transmits according to normal next jumping of SIP routing mechanism searching then.

Fig. 7 execution priority scope that is HSS when IFC priority is set limits the embodiment of inspection; Be provided with limiting under the situation of IFC priority limit of the overall situation in order to explanation in operator by type of service; The inspection flow process that HSS carries out when adjusting an IFC priority comprises the steps:

Step S702, HSS confirms the adjustment of IFC is related to the variation of IFC priority, will carry out the IFC priority limit and limit inspection.

Step S704, HSS are according to the SIP URL information of application service title among the IFC, and inquiry application service type of service table obtains the type of service sign of this IFC institute application associated service.

Step S706, HSS inquires about the priority limit qualified list according to the type of service sign of obtaining among the step S704, obtains the bound scope of the priority of all IFC that are associated with this type of service.

Step S708, the pairing IFC priority limit of the type of service bound that HSS is obtained according to step S706, the inspection said IFC of step S702 set priority confirms that it is whether in said priority limit bound.

Step S710, as among the step S708 said IFC priority being dropped in the priority bound scope, expression HSS limits inspection to the performed priority limit of this IFC to be passed through, and HSS carries out subsequent operation.

The embodiment of Fig. 8 execution priority conflict inspection when single IFC priority is set that is HSS, in order to inspection when newly-built IFC, the adjustment IFC to the conflict flow process of inspection of priority, comprise the steps:

Step S802, HSS judges the variation that the adjustment of IFC is related to IFC priority, will carry out the inspection of IFC PRI conflict.

Step S804, the IFC priority sphere of action that the HSS judgement system is set generates priority sphere of action information.

When the priority sphere of action is a user when subscribing to, priority sphere of action information must comprise the designator of subscribing to for the user in order to indication priority sphere of action, unique identification marking of this user's subscription.Equally, when priority was a business configuration as scope, priority sphere of action information must comprise that being used to indicate the priority sphere of action is the designator of business configuration, the unique identification of this business configuration.Like the priority sphere of action is global scope, and it is the designator of the overall situation that priority sphere of action information only comprises in order to indication priority sphere of action.

Step S806; The priority that HSS relies on the priority sphere of action information that produced and IFC to set is removed the search index table, has equal priority if retrieve the IFC of non-IFC, promptly thinks PRI conflict to occur; The prompting mistake is interrupted follow-up processing flow.

Step S808 if the priority that in step S806, detects the IFC that need to set does not produce conflict with the priority of existing IFC in sphere of action, then confirms the retouching operation of IFC.

Step S810, HSS have confirmed that the priority of revising this IFC in the IFC priority list then of IFC is new priority.

To be HSS concentrate the priority of a plurality of IFC to carry out the embodiment of conflict inspection to share I FC to Fig. 9,,, may further comprise the steps the flow process of all IFC execution priority conflicts inspections wherein in configuration, when revising share I FC collection in order to inspection:

Step S902, HSS judges the variation that the adjustment of share I FC collection is related to IFC priority, will carry out the inspection of IFC PRI conflict.

Step S904, HSS to each IFC execution priority conflict inspection in the share I FC collection, if any PRI conflict, then point out mistake successively, interrupt follow-up processing flow.

To the PRI conflict inspection that share I FC concentrates each IFC, carry out according to embodiment 7 said methods.To the inspection of the priority of IFC arbitrarily in the share I FC set, relate to the user data that in this share I FC collection, has or not PRI conflict and comprise share I FC collection and have or not the IFC PRI conflict.

Step S906 is if after share I FC collection executed IFC PRI conflict inspection, HSS then carried out the renewal operation of follow-up share I FC collection.

Step S908, HSS upgraded share I FC collection after, share I FC is concentrated each IFC, the priority of revising this IFC in the IFC priority list is new priority.

Figure 10 is that HSS issues the embodiment that customer service disposes to S-CSCF, and in order to be described in HSS when S-CSCF issues the customer service configuration data, HSS carries out the inspection flow process of IFC PRI conflict.This embodiment can comprise that S-CSCF download user data and HSS in the endpoint registration process notify user data downloading process such as S-CSCF when user data changes, may further comprise the steps:

Step S1002, HSS comprise user's business configuration to S-CSCF download user data.

Step S1004 after HSS inquires user data, is issuing user data before S-CSCF, earlier user data is carried out the inspection of IFC PRI conflict.

The principle that the system of starting from seamlessly transits can not once all be accomplished in the adjustment the correction of IFC PRI conflict, therefore, when HSS arrives S-CSCF in the download user data, still need carry out simple inspection and conflict correction.

HSS is when extracting the data of a business configuration, and with independent IFC, the concentrated IFC of share I FC that inspection wherein comprises, inspection has or not PRI conflict.If any PRI conflict, HSS has the priority of the IFC of conflict according to the simplest enumerative principle correction in proper order.HSS need clearly write down this conflict simultaneously, and the conflict of being write down will be reacted in the Operation & Maintenance System.

Step S1006 after HSS checked user data, uses Cx interface to issue user data to S-CSCF.

Step S1008, S-CSCF upgrade local customer service configuration after receiving Notification of Changes and receiving the customer service configuration of renewal, and return the download successful respond to HSS.

Step S1010, the flow processing that the user data that the S-CSCF utilization is obtained from HSS in subsequent process responds.Typically, comprise that the IFC that utilizes in the user data carries out service trigger.

In sum; Adopt processing method of the present invention, be applied in the IMS system user business configuration, when different business being configured in quote share I FC collection; Can check effectively and IFC PRI conflict situation whether occur; Ensured that IFC priority can not cause conflict in the business configuration, and flexible configuration, favorable compatibility had.

The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
