Abstract

One embodiment of the application provides a service trigger method. The method comprises the following steps: a serving call session control function S-CSCF acquires the state information of an application server AS; when the serving call session control function S-CSCF receives a service request, the serving call session control function S-CSCF judges whether the application server AS is normal or not based on the state information of the application server AS; if the application server AS is normal, the serving call session control function S-CSCF uses pre-acquired initial filter criteria iFC to perform service matching; and if the service matching succeeds, the serving call session control function S-CSCF triggers a service. According to the application, by taking the acquired state of the application server AS as a necessary condition for service trigger matching, unnecessary initial filter criteria iFC matching and service trigger processes carried out by the serving call session control function S-CSCF are reduced, and the system load and network load are reduced.

Description

technical field

[0001] The present application relates to the technical field of communications, in particular to a service triggering method and a service triggering device. Background technique

[0002] According to the service triggering mechanism in 3GPP TS 24.229, when the Serving Call Session Control Function (S-CSCF) receives the initial request, it needs to follow the initial filtering rule iFC (Initial Filter Criteria) trigger points for matching, and after the matching is successful, the service is triggered, and the request message is forwarded to the corresponding application server AS (Application Server).

[0003] When the S-CSCF does not receive a response message corresponding to the request, or receives a 408 RequestTimeout response message from the AS, or receives a 504 response message from the AS, the S-CSCF decides whether to continue the service trigger according to the default processing method in the iFC . The default processing methods include: SES...

Embodiment Construction

[0048] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0049] refer to figure 1 , is a flow chart of processing the final response of the application server AS status failure returning non-200OK in the existing service trigger.

[0050] From 10 to 20, after receiving the INVITE request, the S-CSCF triggers the message to the corresponding AS_1 according to the service trigger processing mechanism.

[0051] At 30, AS_1 is in a failure state for some reason, and returns a non-200 OK final response message such as 408 / 5xx to the S-CSCF.

[0052] Response messages include: 100 Trying (Trying), 180 Ringing (Ringing), 181 Call is Being Forwarded (Call is Being Forwarded), 200 Successful Response (OK), 302 Temporary Migration (MovedTemporarily), 400 Bad Request (B...
