Abstract

When contract information of user service signed by login user on AS changes, AS initiates request for updating user data including DSAI data to be modified to HSS. After receiving the request, HSS updates DSAI data. Reply message of successful updating user data is returned back to AS after successful update. After receiving the message, AS considers DSAI data update is successful. At the same time, HSS triggers S-CSCF procedure of downloading user service configuration data (USCD), including iFC information not shielded by DSAI, to be assigned to users. When downloading USCD is failed, initiating request for ending login to S-CSCF in use for assigning users, HSS requests deleting user's login information, and prompts user to restart login request. Then, user restarts login request, and HSS downloads USCD to S-CSCF again.

Description

Adopt dynamic service active information to keep the processing method of data consistency

Technical field

The present invention relates to the communications field, relate in particular to and adopt dynamic service active information to keep the processing method of data consistency.

Background technology

At present; Third generation partner program (3GPP; 3rd Generation PartnershipProject) introduced the basic principle that is used for IMS network and service, adopted the thought of control and 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 to be accomplished by the service call conversation control function (S-CSCF, Serving Call Session Control Function) of IMS key-course.User's service trigger data are represented with " business configuration (Service Profiles) ", and are kept in the home subscriber server (HSS, Home Subscriber Server) as the part of user's configuration (User Profiles) data.As shown in Figure 1; It is the frame diagram of IMS service trigger; Show the built-in function of the related network element of service trigger, interface and each network element; Wherein mainly comprise service call conversation control function (S-CSCF) 102, home subscriber server (HSS) 104 and application server (AS, ApplicationServer) 106.In HSS 104, deposit user's business configuration, comprising initial filter criteria (iFC, initial Filter Criteria).

When the user registers; Or S-CSCF 102 receives an initial request of exhaling session end of non-registered users; When asking like SIP (Session Initial Protocol, initial session protocol), or S-CSCF 102 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 102, comprising initial filter criteria from HSS 104.S-CSCF 102 orders are assessed filtering rule according to the service point in the conversation request; If the filtering rule that meets is arranged; The SIP request is sent to application corresponding server (AS) 106; Provide Session Initiation Protocol processing, platform service to trigger and service logic, otherwise route requests to the destination via application server (AS) 106 by the default route rule.

Professional trigger condition according to the difference of user's signing service, can contain many initial filter criteria in a user's the business configuration through initial filter criteria (iFC) expression, and these initial filter criteria all have priority separately.S-CSCF 102 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) 106 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, and S-CSCF receives call request; And call request mated according to priority orders and each rule, through the mode controlling call path of triggering, and via application server; Like AS1, provide professional.If service appointment and un-activation, application server is to going into to exhale things and be left intact and directly returning.After S-CSCF receives response message, continue the initial filter criteria of coupling time priority, and trigger to other application server, like AS2, calling control.

Apparently, if service appointment and un-activation, like Fig. 2, S-CSCF still will trigger to application server according to initial filter criteria, thereby has caused unnecessary calling control redundancy.IMS control and service detach cause the HSS can't perception service, and all Business Processing all have application server to bear, and have also caused this unnecessary calling control redundancy on the one hand.For fear of this redundancy, introduce a kind of mechanism by application server notice HSS 211 to particular user or business, which iFC can conductively-closed, thereby need not download to S-CSCF.

This mechanism is that present dynamic service active information (DSAI) information element that passes through that adopts is notified HSS relevant dynamic service information by AS.If DSAI is a state of activation, show that then its iFC that is associated need download to S-CSCF by HSS; If DSAI is a unactivated state, show that then its iFC that is associated can conductively-closed, need not download to S-CSCF by HSS.

Fig. 3 has indicated the incidence relation of DSAI and iFC.DSAI is associated with an iFC at least, and all must be triggered to identical AS with the related iFC of DSAI, promptly only allow to be responsible for upgrading the DSAI value by an AS; IFC can be associated with one or more DSAI, also can not related DSAI.The incidence relation of DSAI and this implicit expression of iFC is responsible for safeguarding and storage by HSS.

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 " share inceptive filtering rule set (SiFC, Shared iFC Sets)---below be referred to as to share 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; The related one or more initial filter criteria of each shared iFC collection; 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.Fig. 4 has described senior UML (UML, the Unified Modeling Language) model of business configuration class, comprising iFC assembly and shared iFC collection assembly.When service deployment, can define a plurality of shared iFC collection, the related one or more iFC of each shared iFC collection indicate with unique identifier.

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 implicitly download through predefined unique shared iFC identifier 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, thereby can significantly reduce the data traffic of download interface by this identifier 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.

Therefore, can use the multidate information of DSAI mechanism notice HSS related service, HSS is according to the state of activation shielding iFC related with DSAI of DSAI.If the iFC related with DSAI shielded by HSS, then HSS needs downloading service configuration data again, and the iFC of not conductively-closed is downloaded to S-CSCF through HSS.If the iFC related with DSAI is set to not masked state by HSS by masked state, then HSS still needs downloading service configuration data again, and the iFC of not conductively-closed is downloaded to S-CSCF through HSS.IFC can promptly intactly download by explicitly, or implicitly promptly downloads through sharing the iFC collection, and this depends on concrete business configuration.

In the prior art, as shown in Figure 2, if AS1 has changed professional signatory state, as being revised as un-activation by activation, AS1 upgrades being kept at the DSAI value among the HSS through Sh interface.Upgrade successfully, HSS returns success to AS1 and replys, and triggers the business configuration data downloading process to S-CSCF through Cx interface.If business configuration data downloading process failure will cause the inconsistency of AS1 and S-CSCF configuration data, as stated AS1 deexcitation should business, but S-CSCF has still triggered when receiving this professional SIP call request to the calling of AS1 and has controlled.

In sum; The application of DSAI mechanism at present; The mode that the process of the DSAI data that employing AS renewal HSS preserves and the S-CSCF downloading service configuration data process that HSS distributes to registered users according to the triggering of DSAI data variation are separated; In a sense, this separate mode might cause the inconsistency of AS and S-CSCF data, and has influenced the application and the effect thereof of DSAI mechanism.

Summary of the invention

One or more problems in view of the above; The present invention proposes a kind of processing method that adopts dynamic service active information to keep data consistency; Can solve the process that adopts AS to upgrade the DSAI data that HSS preserves and HSS and trigger the problem that mode that the S-CSCF downloading service configuration data process to the registered users distribution is separated might cause AS and S-CSCF data inconsistency according to the DSAI data variation; Realize the consistency of customer service configuration data, guarantee the application and the effect thereof of DSAI mechanism at AS and S-CSCF.

Keep the processing method of data consistency may further comprise the steps according to employing dynamic service active information of the present invention:

Keep the processing method of data consistency may further comprise the steps according to employing dynamic service active information of the present invention: step S702, dispose dynamic service active information respectively on all application servers of user attaching server and the business of supporting to be disposed;

Step S704, under the situation that the CAMEL-Subscription-Information on the application server changes, application server sends dynamic service active information to the user attaching server and upgrades request;

Step S706, user attaching server update dynamic service active information and to application server feedback successful respond, the user attaching server thinks that dynamic service active information upgrades successfully after receiving successful respond;

Step S708, the user attaching server triggers is to the business configuration data downloading process of the service call session control function entity of registered users distribution;

Step S710; When the user attaching server receives and replys the back or do not receive successful respond from the business configuration Data Update of service call session control function entity is unsuccessful; Initiate registration termination request to service call session control function entity, with the log-on message of request logging off users on service call session control function entity;

Step S712, user initiate register requirement to network once more in registration period, the user attaching server is again to the service call session control function entity download user business configuration data of distributing to the user.

Wherein, in step S708, institute's download business configuration data comprises not by the initial filter criteria information of dynamic service activation information shielding.In step S712, the customer service configuration data comprises not by the initial filter criteria information of dynamic service activation information shielding.

Through method of the present invention; Solved the process that adopts AS to upgrade the DSAI data that HSS preserves and HSS and triggered the problem that mode that the S-CSCF downloading service configuration data process to the registered users distribution is separated might cause AS and S-CSCF data inconsistency according to the DSAI data variation; Realize the consistency of customer service configuration data, guarantee the application and the effect thereof of DSAI mechanism at AS and S-CSCF.

Embodiment

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

The present invention is directed to registered users; When change takes place in the customer service CAMEL-Subscription-Information on application server (AS); Initiate subscribing notification request through Sh interface to home subscriber server (HSS) by application server (AS), the delta data of the DSAI that pulls subscription is initiated the user data update request simultaneously; Comprising DSAI data to be changed, and the notification message waiting timer is set.When home subscriber server (HSS) receives the request of DSAI Data Update; Do not upgrade the DSAI data immediately; But at first trigger process to the download user business configuration data of the service call interactive function (S-CSCF) of distributing to the user, comprising the iFC information that is not shielded, after the data of succeeding are downloaded response message by DSAI; Upgrade the DSAI data, and then trigger notification message to application server (AS).

Application server (AS) receives the notification message about the DSAI data in the time of notification message waiting timer setting, checking is through promptly thinking the success of customer service subscription information update; Otherwise initiate user data update request once more, comprising the overtime situation of notification message waiting timer to home subscriber server (HSS).

Fig. 5 shows the flow chart that keeps the processing method of data consistency according to employing dynamic service active information of the present invention.As shown in Figure 5, this method may further comprise the steps:

Step S502, provider support to have disposed DSAI information on these professional application servers (AS) with all at HSS respectively when disposing business.The user goes up the change CAMEL-Subscription-Information at an application server (AS) of provider, and application server (AS) is initiated the subscribing notification request to HSS, the change notification of the DSAI data that pull subscription.

Step S504, application server (AS) is initiated the request of DSAI Data Update to HSS, comprising current DSAI data message to be updated.

Step S506; HSS receives the request that application server (AS) upgrades the DSAI data; Return success to application server (AS) and to reply; This moment, HSS did not carry out Data Update operation immediately, but triggered the business configuration data downloading process of the S-CSCF that distributes to registered users, comprising not by the iFC information of DSAI information screen.

S508, HSS receive the business configuration Data Update successful respond of S-CSCF, carry out the operation of DSAI Data Update, thereby trigger the notice request to application server (AS);

S510, application server (AS) receives the notice request of HSS, the DSAI data consistent whether the DSAI data in the verification notice request are upgraded with step S502, and show the result who upgrades the DSAI data manipulation.

Further, step S502 also comprises the user data query request of application server (AS) to HSS inquiry DSAI value, obtains current saved DSAI data message in HSS.

Further, step S504 also comprises after application server (AS) receives the successful respond that HSS returns notification message waiting timer and message retransmission maximum times is set;

Further, step S504 also comprises after application server (AS) receives the successful respond that HSS returns and new DSAI data is set for upgrading pending status;

Further; After step S504 comprises that also application server (AS) is provided with the notification message waiting timer; The Messages-Waiting timer expiry, and message sends number of times and do not reach the message retransmission maximum times, and application server (AS) is initiated the request of DSAI Data Update to HSS once more;

Further; After step S504 comprises that also application server (AS) is provided with the notification message waiting timer; The Messages-Waiting timer expiry, and message sends number of times and reaches the message retransmission maximum times, and application server (AS) is no longer initiated the request of DSAI Data Update to HSS; But show that directly upgrading the DSAI data manipulation fails, and does not replace former DSAI data.

Further, step S510 also comprises application server (AS) verification DSAI data consistent, replaces former DSAI data, and new DSAI data are set is update mode, shows simultaneously to upgrade DSAI data manipulation success.

Further, step S510 comprises that also application server (AS) verification DSAI data are inconsistent, the termination messages waiting timer, and message sends number of times and do not reach the message retransmission maximum times, and repeating step S504 does not replace former DSAI data.

Further; Step S510 comprises that also application server (AS) verification DSAI data are inconsistent; The termination messages waiting timer, and message sends number of times and reaches the message retransmission maximum times, do not replace former DSAI data; And new DSAI data are set is update mode, shows simultaneously to upgrade DSAI data manipulation failure.

Fig. 6 has described and the present invention is directed to registered users, is used for dynamic service information and handles conforming flow chart.May further comprise the steps:

Step S602; The user goes up the change service profile at an application server (AS) of provider; Application server (AS) is initiated user data requests (UDR to home subscriber server (HSS); User-Data-Request), inquiry should business be gone up the DSAI data message of preserving at home subscriber server (HSS).

Step S604, home subscriber server (HSS) to application server (AS) return user data reply (UDA, User-Data-Answer), comprising the current DSAI data message that is stored among the HSS.

Among application server (AS) the inspection step S602 data message of service profile change back DSAI whether with step S604 in the DSAI data message that is kept in the home subscriber server (HSS) that inquires consistent; If it is consistent; Application server (AS) is no longer carried out any operation; Promptly need not carry out the DSAI updating data, flow process finishes; Otherwise execution in step S606.

Step S606, application server (AS) to home subscriber server (HSS) initiate the subscribing notification request (SNR, Subscribe-Notifications-Request), the delta data of the DSAI that pulls subscription.

Step S608, home subscriber server (HSS) to application server (AS) return subscribing notification reply (SNA, Subscribe-Notifications-Answer).

Step S610, application server (AS) is initiated configuration data renewal request to home subscriber server (HSS), and (PUR, Profile-Update-Request), the DSAI data are upgraded in request.

Step S612; After home subscriber server (HSS) received configuration data renewal request, the DSAI data were upgraded in the request of discovery, do not upgrade the DSAI data immediately; But the configuration data that directly returns success to application server (AS) upgrade and reply (PUA, Profile-Update-Answer).

After the configuration data that application server (AS) receives success upgrades and to reply; The notification message waiting timer is set in this locality; Be used to receive the successful notification message of DSAI Data Update, and new DSAI data be set, the message retransmission maximum times is set simultaneously for upgrading pending status.

Step S614; The iFC that home subscriber server (HSS) retrieval is related with DSAI; And send to service call conversation control function (S-CSCF) through Cx interface and to push away configuration data request (PPR; Push-Profile-Request), download user business configuration data are comprising the iFC information that is not shielded by DSAI.

Step S616, service call conversation control function (S-CSCF) to home subscriber server (HSS) return push away configuration data reply (PPA, Push-Profile-Answer).

If the success of download user business configuration data, home subscriber server (HSS) upgrades the DSAI data message, thereby triggers step S618.

If download user business configuration data are unsuccessful, home subscriber server (HSS) does not upgrade the DSAI data message, thereby can not trigger step S618.At this moment, application server (AS) can not receive the notification message of DSAI Data Update, and the notification message waiting timer is overtime, and inspection message sends number of times and whether reach the message retransmission maximum times, if do not reach, and repeating step S610 then; Otherwise upgrade the DSAI data failure, former DSAI data do not change.

Step S618, home subscriber server (HSS) to application server (AS) initiate to push away notice request (PNR, Push-Notification-Request), comprising the DSAI data message after upgrading.

Step S620, application server (AS) receive push away notice request (PNR, Push-Notification-Request) after, the DSAI data message that checking is carried in the message whether with local data base in the new DSAI data message preserved consistent.

If the DSAI data message is consistent, check whether new DSAI data are to upgrade pending status, if; Then stop the notification message waiting timer; And new DSAI data are set is update mode, replaces former DSAI data with new DSAI data simultaneously, and the notice that pushes away that returns success is replied (PNA; Push-Notification-Answer), flow process finishes; Otherwise the notice that pushes away that returns success is replied PNA, and flow process finishes.

If the DSAI data message is inconsistent, check whether new DSAI data are to upgrade pending status, if; Return the notice that pushes away of failure and reply PNA; Comprising the invalid error message of DSAI (DIAMETER_ERROR_DSAI_NOT_AVAILABLE), and stop the notification message waiting timer, inspection message is sent number of times and whether is reached the message retransmission maximum times; If do not reach, repeating step S610 then; Otherwise upgrade the DSAI data failure, former DSAI data do not change.

If new DSAI data are update mode; Explain that then the DSAI data change in the home subscriber server (HSS); Application server (AS) upgrades the DSAI data message synchronously, and comprising new DSAI data that are provided with in this example and former DSAI data, and the notice that pushes away that returns success is replied PNA.

Compared with prior art; Because the present invention is in the application process of DSAI mechanism; Through notification message related Update Information process and HSS of AS trigger the process of data download thus; Make AS can learn whether data download success of HSS through notification message; If unsuccessful then initiate renewal process once more to HSS, therefore solved the process that adopts AS to upgrade the DSAI data that HSS preserves and HSS and triggered the problem that mode that the S-CSCF downloading service configuration data process of distributing to registered users is separated might cause AS and S-CSCF data inconsistency according to the DSAI data variation, guaranteed machine-processed application and the effect thereof of DSAI.

The present invention is directed to registered users; When change takes place in the customer service CAMEL-Subscription-Information on application server (AS); Initiate user data update request through Sh interface to home subscriber server (HSS) by application server (AS), comprising DSAI data to be changed.

Home subscriber server (HSS) upgrades the DSAI data after receiving the user data update request from application server (AS) immediately, upgrades the successfully back user data update response message that returns success to application server (AS).Application server (AS) receives the user data update response message of success, thinks that promptly the DSAI Data Update is successful.

Meanwhile, home subscriber server (HSS) triggers the process to service call interactive function (S-CSCF) the download user business configuration data of distributing for the user, comprising the iFC information that is not shielded by DSAI.Customer service configuration data failed download, home subscriber server (HSS) is initiated registration termination request to the service call interactive function (S-CSCF) that the user distributes, request deletion user's log-on message, and impel the user to initiate register requirement again.Then the user initiates register requirement again, and home subscriber server (HSS) is again to service call interactive function (S-CSCF) the download user business configuration data of distributing for the user.

Fig. 7 is the flow chart that keeps the processing method of data consistency according to employing dynamic service active information of the present invention.As shown in Figure 7, this method may further comprise the steps:

Step S702, provider support to have disposed DSAI information on these professional application servers (AS) with all at HSS respectively when disposing business.

S704, the user goes up the change CAMEL-Subscription-Information at an application server (AS) of provider, and triggers this professional dynamic service active information (DSAI) is delivered to HSS through Sh interface via application server (AS) process.Application server (AS) is initiated the request of DSAI Data Update to HSS.

S706, HSS receive the request that application server (AS) upgrades the DSAI data, carry out the Data Update operation immediately, and the success back returns success to application server (AS) replys, and application server (AS) thinks that promptly the DSAI Data Update is successful after receiving successful respond.

S708, HSS trigger the business configuration data downloading process of the S-CSCF that distributes to registered users, comprising not by the iFC information of DSAI information screen.

S710, HSS receive that the business configuration Data Update of S-CSCF is unsuccessful replys or do not receive response message, initiate the registration termination request to S-CSCF, and the request logging off users is at the log-on message of S-CSCF, and impel the user to register again.

S712, user initiate the register requirement to network once more in registration period, the S-CSCF download user business configuration data that HSS distributes to the user in registration process again are not comprising by the iFC information of DSAI information screen.

Fig. 8 has described and the present invention is directed to registered users, is used for dynamic service information and handles conforming flow chart.As shown in Figure 8, may further comprise the steps:

Step S802; The user goes up the change service profile at an application server (AS) of provider; Application server (AS) is initiated user data requests (UDR to home subscriber server (HSS); User-Data-Request), inquiry should business be gone up the DSAI data message of preserving at home subscriber server (HSS).

Step S804, home subscriber server (HSS) to application server (AS) return user data reply (UDA, User-Data-Answer), comprising the current DSAI data message that is stored among the HSS.

Among application server (AS) the inspection step S802 data message of service profile change back DSAI whether with step S804 in the DSAI data message that is kept in the home subscriber server (HSS) that inquires consistent; If it is consistent; Application server (AS) is no longer carried out any operation; Promptly need not carry out the DSAI updating data, flow process finishes; Otherwise execution in step S806.

Step S806, application server (AS) is initiated configuration data renewal request to home subscriber server (HSS), and (PUR, Profile-Update-Request), the DSAI data are upgraded in request.

Step S808; After home subscriber server (HSS) received configuration data renewal request, the DSAI data were upgraded in the request of discovery, upgrade the DSAI data immediately; And the configuration data that returns success to application server (AS) upgrade and reply (PUA, Profile-Update-Answer).The configuration data that application server (AS) receives success upgrades to reply promptly thinks the success of DSAI Data Update after (PUA).

Step S810; The iFC that home subscriber server (HSS) retrieval is related with DSAI; And send to service call conversation control function (S-CSCF) through Cx interface and to push away configuration data request (PPR; Push-Profile-Request), download user business configuration data are not comprising by the iFC information of DSAI information screen.

Step S812, service call conversation control function (S-CSCF) to home subscriber server (HSS) return push away configuration data reply (PPA, Push-Profile-Answer).If download user business configuration data are unsuccessful or do not receive and push away configuration data and reply (PPA) message, method then proceeds to step S814.

Step S814; Home subscriber server (HSS) change user's login state is unregistered; And (RTR Registration-Termination-Request), nullifies former because SERVER_CHANGE to send registration termination request to the service call conversation control function (S-CSCF) that distributes for the user; Ask the log-on message of logging off users, and force the user to initiate heavily to register at service call conversation control function (S-CSCF).

Step S816; Service call conversation control function (S-CSCF) receives the registration termination request (RTR) from home subscriber server (HSS); Deletion user's log-on message is provided with the user and is unregistered state, and initiates the network de-registration request to the user; The Registration Termination Answer that returns success simultaneously (RTA, Registration-Termination-Answer) message.The user can initiate register requirement to network once more in the registration period of regulation; Home subscriber server (HSS) can be in registration process again to service call conversation control function (S-CSCF) download user business configuration data, comprising not by the iFC information of DSAI information screen for user's distribution.

Compared with prior art; Because the present invention is in the application process of DSAI mechanism; Send registration termination request message through HSS to the S-CSCF that the user distributes; Force the user to initiate registration to network again; Thereby reach HSS once more to the purpose of S-CSCF download user business configuration data, therefore solved the process that adopts AS to upgrade the DSAI data that HSS preserves and HSS and triggered the problem that mode that the S-CSCF downloading service configuration data process of distributing to registered users is separated might cause AS and S-CSCF data inconsistency, guaranteed machine-processed application and the effect thereof of DSAI according to the DSAI data variation.

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.
