Step 303:HSS returns response message after receiving described querying command, and carries AS requesting users circuit domain CAMEL-Subscription-Information in this response message.
After HSS receives the querying command of described expansion, at first obtain subscriber line circuit territory CAMEL-Subscription-Information, then the subscriber line circuit territory CAMEL-Subscription-Information that obtains is returned to AS from attaching position register HLR or inner HLR subclass.In this process, if AS is different with the form of the subscriber line circuit territory CAMEL-Subscription-Information that HLR can discern, then the subscriber line circuit territory CAMEL-Subscription-Information that also needed to obtain before HSS sends to AS with the subscriber line circuit territory CAMEL-Subscription-Information that obtains is converted to Diameter form or XML form.
HSS will be described in detail later from the process that HLR obtains subscriber line circuit territory CAMEL-Subscription-Information.
HSS can comprise supplementary service information from the subscriber line circuit territory CAMEL-Subscription-Information that HLR obtains, and specifically has: the service code of supplementary service, the state information of supplementary service, corresponding basic service group code information etc.
With reference to Fig. 4, Fig. 4 is the realization flow of second embodiment of the IP Multimedia System of the present invention method of using the acquisition cuicuit domain information, may further comprise the steps:
Step 401: the Sh interface between expansion AS and the HSS makes its subscription of supporting subscriber line circuit territory CAMEL-Subscription-Information and notice issue.
Particularly, expand Sh interface in the present invention, its User Status change notification of supporting the subscriber line circuit territory is subscribed to and the notice issue; In addition, can also expand Sh interface, its supplementary service information change notification of supporting the subscriber line circuit territory is subscribed to and the notice issue.Below this is elaborated respectively.
The present technique field personnel know, in the prior art, Sh interface is not supported the function of circuit domain information subscribing notification.In the present invention, can expand Sh interface, with the User Status change notification message of existing Sh-Subs-Notif order, so that it supports the User Status of circuit domain to change the function of subscribing notification as booking reader's circuit domain; In addition, can also increase new value to the data refer parameter in the existing Sh-Subs-Notif order, every kind of subscriber line circuit territory supplementary service information type that the corresponding a kind of AS of new value need subscribe to is so that it supports the subscribing notification function of circuit domain supplementary service information.Can also further expand the Sh-Subs-Notif order, can also increase the new parameter of a class again except the data refer parameter increases new value, the newly-increased parameter of this class is used for further identifying the data that AS asks, and can comprise two concrete parameters simultaneously:
(1) identify the parameter of the supplementary service information of hanging under a certain class basic service of this subscription operation AS request, this parameter is used to carry basic service group code.
(2) identify the parameter of the supplementary service of this subscription operation AS request, this parameter is used to carry Supplementary Service Code.
Above-mentioned these two parameters can occur in Sh-Subs-Notif order simultaneously, any one also can only occur wherein, perhaps do not occur simultaneously.
Step 402:AS sends Sh-Subs-Notif request, booking reader's circuit domain information by Sh interface to HSS.
AS can have following several situation to the Sh-Subs-Notif request that HSS sends:
(1) AS sends the Sh-Subs-Notif request that only comprises Mobile Subscriber International ISDN Number and described data refer parameter, the supplementary service information of subscribing to all basic services and hanging down to HSS.
(2) AS sends the Sh-Subs-Notif request that comprises Mobile Subscriber International ISDN Number, described data refer parameter and described basic service set code parameters to HSS, subscribes to all supplementary service information of hanging under this specific basic service set.
(3) AS sends the Sh-Subs-Notif request that comprises Mobile Subscriber International ISDN Number, described data refer parameter and described supplementary service code parameters to HSS, subscribes to this specific supplemental business information of hanging under all basic service set.
(4) AS sends the Sh-Subs-Notif request that comprises Mobile Subscriber International ISDN Number, described data refer parameter, described basic service set code parameters and described supplementary service code parameters, this specific supplemental business information of inquiring about the following extension of hanging under this specific basic service set to HSS.
Step 403:HSS writes down this subscribing relationship after receiving the Sh-Subs-Notif request.
Step 404:HSS to the AS message that makes an announcement, wherein carries the subscriber line circuit domain information that AS subscribes to when the subscriber line circuit domain information changes.
HLR perceives after the user roams the back for the first time attach operation or VLR (VLR Visitor Location Register) remove the incident of a user data, sends the message that User Status changes to HSS.HSS receive after the message that User Status that HLR sends changes according to subscribing relationship with the User Status change events and the state after changing send to AS.
HLR perceive VLR to HLR send data after message synchronization is upgraded or keeper by HLR interface change user supplementary service data after, send the message that user's supplementary service changes to HSS.After HSS received the message that user's supplementary service that HLR sends changes, the state information and the basic service set of the supplementary service after will changing according to described subscribing relationship sent to AS.
The present invention makes its inquiry of supporting subscriber line circuit territory CAMEL-Subscription-Information or subscription and notice issue by Sh interface is expanded, and like this, AS just can inquire about or subscribe to HSS by Sh interface, thereby obtains the subscriber line circuit domain information.
With reference to Fig. 5, Fig. 5 shows the realization flow of method first embodiment of IP Multimedia System application circuit domain information of the present invention, may further comprise the steps:
Step 501:AS asks subscriber line circuit territory CAMEL-Subscription-Information by Sh interface to HSS.

Because in the network evolution process in future, HSS and HLR may be positioned at same physical entity (the embedded HLR subclass of HSS), also may separate and set up, and that is to say to be respectively independent function entity.At both of these case, the present invention provides HSS to obtain the detailed process of subscriber line circuit territory CAMEL-Subscription-Information from HLR respectively.
When the embedded HLR subclass of HSS, HSS obtains user's all kinds of circuit domain CAMEL-Subscription-Information from HLR by internal interface.At first, HSS comprises user's Mobile Subscriber International ISDN Number to the request message of HLR transmission inquiring user circuit domain information in the message, information inquiring indication etc.; After HLR receives this request message, judge that Mobile Subscriber International ISDN Number exists the back to return subscriber line circuit numeric field data information according to request to HSS.
When HSS and HLR were positioned at different physical entities, HSS obtained user's all kinds of circuit domain CAMEL-Subscription-Information from HLR by external interface.During specific implementation, can adopt following several mode:
(1) HSS intercepts and captures the response message that the request of mailing to HLR and all HLR send by the signaling catching mode, and obtains the subscriber line circuit territory CAMEL-Subscription-Information of HLR inside according to the relation of request and response;
(2) HSS obtains subscriber line circuit territory CAMEL-Subscription-Information by inquiry mode from HLR as the service control point (SCP);
(3) HSS obtains subscriber line circuit territory CAMEL-Subscription-Information by the subscribing notification mode from HLR as SCP.
Fig. 6 is HSS when being positioned at different physical entity with HLR, and HSS obtains the message interaction process of a kind of embodiment of subscriber line circuit domain information from HLR:
61.HSS send ATSI order (for the WCDMA network) or service request (Service Request) message (for cdma network) to HLR as required, request inquiring user circuit domain data;
62.HLR after the request of receiving judges that Mobile Subscriber International ISDN Number exists, judge whether the data of request are effective;
63. if the data of request are effective in 62, then HLR returns subscriber line circuit numeric field data information, otherwise, return errored response.
With reference to Fig. 7, Fig. 7 shows the realization flow of method second embodiment of IP Multimedia System application circuit domain information of the present invention, may further comprise the steps:
Step 701:AS by Sh interface to HSS booking reader's circuit domain information.
Step 702:HSS perception subscriber line circuit domain information changes.
