Description
Technical field
The present invention relates to the communications field, particularly relate to group's data in a kind of IMS network and store the method, server and the system that realize dialling mutually.
Background technology
IMS (IpMultimediasubsystems, IP Multimedia System) use the method for layering to design it by 3GPP standard, business can be realized and control is separated, Call-Control1 and media delivery are separated, its carrying is provided by the transport layer of bottom, service logic is then realized by application layer, application layer in IMS comprises home signature user server (HomeSubscriberServer, and application server (ApplicationServer HSS), AS), HSS and AS is connected by SH interface.Wherein, HSS is the central database storing user related information, and AS is to provide the entity of value added multimedia business, and the major function of AS is the logical requirements that the business information of contracting according to service-user completes corresponding service.
In the ims network, multiple user can form a Centrex (CENTRalExchange, Centrex, also known as centrex) group, user in Centrex group not only can have one or more overall routable trombone, can also have a cornet, the cornet that the user in various ce ntex group has can repeat.A Centrex group can comprise one or more groups, and in same Centrex group, the cornet of the user of different group also can be identical.
Therefore, the user in same group in same Centrex group both can be dialled by overall routable trombone mutually, also can be dialled mutually by the cornet of Tel form.In same Centrex group, the user of different group both can be dialled by overall routable trombone mutually, also can add cornet by the called group number of Tel form and dial mutually.Now, need the AS of calling subscriber's home domain this cornet to be converted to corresponding trombone, therefore, need to store in the ims network the trombone of user and the corresponding relation of cornet in Centex group, so that AS searches trombone corresponding to cornet according to this corresponding relation.
At present, the group number of user, group number and cornet information is not comprised in the AVP of SH interface (AttributeValuePairs, transitive attribute value to).If the trombone of all Centex groups and the corresponding relation of cornet are stored in HSS as transparent data, then due to when the user in same group of same Centex group dials mutually with cornet, the group of calling subscriber number cannot be brought HSS with the group number of calling subscriber by SH interface by the AS of calling subscriber's home domain, or the user in different groups of same Centex group with called group number add cornet dial mutually time, the group of calling subscriber number cannot be brought HSS with the group number of called subscriber by SH interface by the AS of calling subscriber's home domain, therefore, HSS cannot determine to inquire about trombone corresponding to the cornet of called subscriber in which group of which group, thus the corresponding relation of cornet and trombone cannot be accomplished.
At present in order to solve the problem, need the cornet of all users in the Centrex group at home domain user place and the corresponding relation of trombone to be stored in the AS database in user attaching territory.Now, when user in same group of same Centex group dials mutually with cornet, the AS of calling subscriber's home domain is according to the Centrex group of calling subscriber number, the group number of calling subscriber and the cornet of called subscriber, inquire about the trombone corresponding to cornet of called subscriber in the Centrex group of direct calling subscriber in the local database, thus the cornet of called subscriber is converted to the trombone of called subscriber.When user in different groups of same Centex group dials mutually with cornet, the AS of calling subscriber's home domain is according to the Centrex group of calling subscriber number, the group number of called subscriber and the cornet of called subscriber, inquire about the trombone corresponding to cornet of called subscriber in the respective sets of direct corresponding Centrex group in the local database, thus the cornet of called subscriber is converted to the trombone of called subscriber.
Although the method user that can solve in same Centrex group carries out the problem dialled mutually with cornet, but, due to the non-centrality that data store, the repeated storage of data may be caused, such as, when the user of different home domain forms same Centrex group, in the local data base of the AS of these home domain, all need to store the cornet of all users and the corresponding relation of trombone in this Centrex group, and this data storage method does not meet the principle of unified management user related data in IMS architecture.

Embodiment
Solution for embodiment of the invention is mainly by being stored in the local HSS in unified GlobalHSS or corresponding user attaching territory by the directory of cornet in all Centrex groups and trombone, group number and group number corresponding relation, and between each HSS and corresponding AS SH interface AVP in increase group number, group number and cornet three fields, to realize group business mutually between Centrex user inside the group, especially realize the extension number dialing business between user inside the group.
As shown in Figure 1, one embodiment of the invention proposes group's data in a kind of IMS network and stores the method realizing dialling mutually, comprising:
Step S101, HSS storage comprises the directory of corresponding relation between cornet and trombone in Centrex group, group number and group number;
The present embodiment method is based on IMS network application layer, and as previously mentioned, the application layer in IMS comprises home signature user server HSS and application server AS.Wherein, HSS is the central database storing user related information, and key data comprises user identity, log-on message, subscription authentication, Roaming Authorization, the S-CSCF information of distributing and Service Trigger Information etc.AS is to provide the entity of value added multimedia business, and the major function of AS is the logical requirements that the business information of contracting according to service-user completes corresponding service.
In IMS system, the subscription data of user leaves HSS in, and AS is by SH interface accessing user contracting data.Owing to there is multiple HSS in an IMS network, in order to AS need calling party subscription data time, the HSS depositing specific user's data can be found, current 3GPP introduces Subscription Locator Function (SubscriptionLocatorFunction, SLF), possess the mapping relations that specific user indicates corresponding HSS in the above, namely connected by SLF between each HSS, AS is used for realizing the location of HSS respectively by SH interface polls SLF.
SH interface is the interface between AS and HSS, and its major function is as AS provides the information of corresponding service user, thus realizes the corresponding service of this service-user.
Each AS all can use DIAMETER agreement (aaa protocol of a new generation) to select to engage in the dialogue with a HSS on SH interface.DIAMETER agreement is a kind of agreement for performing authentication, mandate and account management (AAA) in ims.This agreement is that the transitive attribute value that be followed by one by one by a head is formed AVP.Each AVP comprises a head and packaged agreement particular data and authentication, authorization and accounting information etc.
In the present embodiment, HSS can be the local HSS of an overall GlobalHSS or relative users home domain.
In the ims network, multiple user can form a Centrex group, and the user in Centrex group not only can have one or more overall routable trombone, and can also have a cornet, the cornet that the user in various ce ntex group has can repeat.A Centrex group can comprise one or more groups, and the cornet of the user in different groups in same Centrex group also can be identical.
Therefore, the user in same group in same Centrex group both can be dialled by overall routable trombone mutually, also can be dialled mutually by the cornet of Tel form.User in different groups in same Centrex group both can be dialled by overall routable trombone mutually, also can add cornet by the called group number of Tel form and dial mutually.Now, need the AS of calling subscriber's home domain this cornet to be converted to corresponding trombone, therefore, need to store in the ims network the trombone of user and the corresponding relation of cornet in Centex group, so that AS searches trombone corresponding to cornet according to this corresponding relation.
In the present embodiment, the corresponding relation of all cornets in all Centrex groups and trombone, group number and group number is divided according to affiliated group and group, be stored in the form of directory in the local HSS of relative users home domain or be stored on an overall GlobalHSS, during storage, following two kinds of embodiments can be adopted: 1, when user opens an account on HSS or after opening an account, the directory of corresponding relation between the user group corresponding with trombone number, group number and cornet is directly set in the HSS of correspondence; 2, by AS, the group corresponding with user's trombone number, group number, cornet are updated in the directory in HSS.
When the group corresponding with user's trombone number, group number, cornet being updated on the local HSS in user attaching territory or the GlobalHSS of the overall situation by AS, the field of group number, group number, cornet is increased, the Data-Reference field of expansion SH interface in the AVP of SH interface.
