Description

Method and system for updating user initial filtering rules

TECHNICAL FIELD The present invention relates to the field of communications technologies, and in particular, to a method and system for updating a user initial filter criteria.

Background technique

The Sh interface is an interface between an Application Server (AS) defined by the 3rd Generation Partner Project (3GPP) and a Home Subscriber Server (HSS), and is used between the AS and the HSS. Information interaction, including Data handling procedures, Subscription/Notification procedures. The Sh process of the prior art is as shown in FIG. 1 and includes the following processes: a. The data operation process specifically includes the following steps: Step 1. The AS sends a Sh-Update message to update the user service data stored in the HSS. Step 2. The HSS sends a Sh-Update Resp message to confirm that the modification is successful. b. The subscription/notification process includes the following steps: Step 3. The user registers with the network; Step 4. The S-CSCF downloads the user from the HSS. Data; Step 5. The S-CSCF registers the request with the user back to 200 OK; Step 6. The S-CSCF sends a third party registration to the AS; Step 7. The AS returns 200 OK; Step 8. After the third registration, the AS sends Sh- to the HSS. Subs-Notif (Sh subscription notification), subscribe to relevant information, and download the required business data at the same time; Step 9. The HSS confirms the subscription and returns some data to the AS. Step 10. At some subsequent time, the AS needs to update the data, and then sends a Sh-Update to the HSS to update the service data stored in the HSS. Step 11. HSS sends The Sh-Update Res message confirms that the modification is successful; Step 12. At some subsequent time, if the service data in the HSS changes, and the AS has previously subscribed to the HSS, the HSS sends the Sh-Notif to the AS; Step 13. AS Return confirmation notice. In the actual application of the IP Multimedia Subsystem (IMS), the AS needs to actively modify the user's iFC so that the call of this user can trigger the scenario to the AS. For example, in some scenarios, the behavior of the AS is the Routeing Back to Back User Agent (Routeing Back to User Agent, Route B2BUA) behavior mode, and different dialog identifiers (Dialog IDs) are used on both sides of the call. However, according to the iFC, the AS is not in the subsequent trigger sequence of the user. When the user initiates a new call request and carries the Replace header, the S-CSCF does not trigger the call to the AS. Since the call is not triggered to this AS, the Dialog information of the final Replace header will be unrecognized on the other side, causing the call to be released. At this point, a mechanism needs to be introduced that allows the AS to actively update the user iFC and cause subsequent calls to be triggered to the AS. In addition, in some scenarios, if you need to update the iFC of the registered user, it is not enough to update the iFC data in the HSS. Because the S-CSCF has downloaded the user data, you need to trigger the HSS to update the data downloaded by the S-CSCF. . Currently, there is no corresponding solution in the prior art for implementing the AS update HSS and the user iFC in the S-CSCF.
