Embodiment 1

[0078] Embodiment 1 describes that for the redundant AS set for the default AS, the IFC of the redundant AS is added in the user subscription information table, and the S-CSCF network element matches the IFC of the redundant AS, and then realizes that when the default AS is due to When a fault fails to provide services to users, the redundant AS is triggered to replace the corresponding default AS to provide services to users.

Embodiment 2

[0079] Embodiment 2 describes that a redundant correspondence table is added in the S-CSCF network element, and the redundant correspondence table records the correspondence between the default AS and the corresponding redundant AS; when the default AS is due to When a fault fails to provide services to the redundant AS normally, the S-CSCF network element searches the redundant correspondence table to determine whether there is a corresponding redundant AS in the default AS, and if so, triggers the redundant AS to provide services to users.

[0080] Embodiment one

[0081] In this embodiment, a corresponding redundant AS1' is set for the default AS1, and the redundant AS1' has the same function as the default AS1.

[0082] Because the S-CSCF network element triggers the AS to provide services to the user by matching the service IFC in the user subscription information. Therefore, in order to enable the redundant AS1' to replace the default AS1 to provide services to users wh...

Abstract

The invention discloses a method for improving service reliability, setting a corresponding redundant AS (application server) for one or above default AS, and when S-CSCF network element triggers the default AS to provide service for a user, executing the steps of: A. when determining the default AS can not provide service for a user because of failure, the S-CSCF network element triggers the redundant AS corresponding to the default AS to provide service for the user. Additionally, it provides a system for improving service reliability. And it avoids service loss and assures quality of service for users.

Description

technical field [0001] The invention relates to IP-based multimedia subsystem (IMS) technology, especially a method and system for improving service reliability. Background technique [0002] During an initial service request triggering process on the IMS network, the serving call session control network element (S-CSCF) will match the initial filter criterion (IFC) in the user subscription information according to the received user's initial service request message, and will match The received initial service request messages are sequentially triggered to different application servers (AS), and then different types of services are provided to users through different ASs. [0003] There are many types of initial service request messages, such as session initial service request messages for session services, subscription initial service request messages for subscription services, and registration initial service request messages for third-party registration. Since the S-CSCF...
