Embodiment 1

[0024] According to an embodiment of the present invention, a method for troubleshooting in an IMS network is provided. Considering that in the prior art, when an AS fails, the CSCF network element of the IMS network will disconnect the call of the user, so in order to avoid this Before this method is implemented, it is necessary to optimize the configuration rule of the initial filtering criterion iFC parameter to (DEFHND=SESSION_CONTINUED), that is, the default trigger rule of not releasing the call when the AS is unreachable. Then in the IMS network, configure the iFC (Initial Filter Criteria, initial filter rule) on the S-CSCF (Servlng-Call Session Control Function) network element to not release the call when the AS is unreachable. After the state of the AS, the method mainly includes: the S-CSCF detects whether the AS is faulty by sending a state detection message to the AS in real time; and, after detecting the AS fault, directly forwards the received call session reques...

Embodiment 2

[0047] This embodiment provides a system for fault handling in an IMS network, such as Figure 5 As shown, it includes: AS, S-CSCF network element, and I-CSCF network element, wherein, the IFC parameter on the S-CSCF network element is configured as a trigger rule that the call is not released when the AS is unreachable.

[0048] The S-CSCF network element is used to detect whether the AS is faulty by sending a status detection message to the AS in real time;

[0049] The I-CSCF network element is configured to send a call request session message requesting access to the AS to the S-CSCF according to the INVITE message from the MGCF network element;

[0050] The S-SCSF network element is also used to directly forward the call session request message requesting access to the AS to the MGCF network element in the IMS network after detecting the failure of the AS.

[0051] Further, the S-CSCF network element is specifically used to periodically send the session initialization pr...

Abstract

The invention discloses a fault processing method and system in an IMS network, relates to the communication technical field, and solves the technical problem in the prior art that the time for hand-operated connection of IMS business is too long, thus causing users unable to have a conversation. In the IMS network, an iFC parameter on an S-CSCF network element is configured with a trigger rule in which a calling is not released when AS is inaccessible; the method comprises the following steps: the S-CSCF network element sends state detection message in real time to the AS so as to determine whether the AS is in failure or not; when AS fault is detected, a received calling conversation request message of requesting to access the AS is directly forwarded to a MGCF network element. The method and system are mainly used in IMS business.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for fault handling in an IMS network. Background technique [0002] IMS (IP Multimedia Subsystem, IP Multimedia Subsystem), as an access-independent network architecture based on IP packet transmission, can realize fixed-mobile convergence, voice, data, video and other multi-service convergence, as well as IT and CT convergence. However, while IMS converged communication products provide users with rich and colorful multimedia service (such as voice) experience, they also bring the following problems: [0003] When a mobile phone user subscribes to the One Number service, the SCP (Service Control Point, Service Control Point) routes the call to the IMS network, and the AS (Application Server) is responsible for the simultaneous ringing / sequential ringing processing of the called One Number Logic, if the AS network element fails at this time, such as f...
