Inceptive filtering regulation processing method

Abstract

The present invention provides a processing method of an initial filter criteria, the method comprises S302, which a service call dialogue control functional entity checks whether the failure criteria of a user logon caused due to the logon failure of a third party is existent in the logon initial filter criteria of user data saved; S304, under the condition of the initial filter criteria of the user logon failure caused due to the failure of the third party, the service call dialogue control functional entity performs the thirty party triggering and processes the initial filter criteria of the user logon failure caused due to the failure of the third party according to the logon initial filter criteria in the user data, and distributes a successful response after the process of the initial filter criteria of the logon failure caused due to the failure of the third party is completed; and S306, which the service call dialogue control functional entity performs the third party logon according to the untreated initial filter criteria if the untreated logon initial filter criteria is still existent after distributing the successful logon response, until the initial filter criteria is processed completely.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for processing initial filtering rules. Background technique [0002] The IP Multimedia Core Network Subsystem (IMS for short) is based on the SIP protocol (an application layer protocol that creates, modifies, and terminates sessions between two or more parties). The main functional entities in IMS include the call control entity CSCF (Serving Call Session Control Function) that controls functions such as user registration and session control, the home subscriber server HSS (Home Subscriber Server) that centrally manages user subscription data, and the server that provides various business logic control functions. Application server AS (Application Server). [0003] Figure 1 is a flow chart of IMS user registration and user registration status subscription. It mainly involves the following network elements and equipment: UE (User Equipment), which is user equipment; ...

AI Technical Summary

Problems solved by technology

[0014] S224, the third-party registration failure causes the S-CSCF to initiate a network logout, and the S-CSCF deletes the user data. Since the UE and the P-CSCF have not successfully subscribed to the registration status at this time, the UE and the P-CSCF cannot know that the user on the S-CSCF has was canceled

[0015] If the above failure occurs, the session request and non-session request initiated by the UE will not succeed until the UE re-registers.

And because the UE state is still unregistered, this period of time will be very long (half of the successful registration response time)

This defect not only causes data inconsistency on UE, P-CSCF, S-CSCF, and HSS, but also leads to serious consequences that users cannot use the IMS communication network
