Embodiment Construction

[0052] In the IMS network of the embodiment of the present invention, service data and user terminal data are stored on the HSS. When the AS is started, there is no service data and user terminal data in the initial state. Only when the AS receives the registration signaling of the user terminal, it will download the service data and user terminal data of the user terminal from the HSS. In this way, when the service request signaling of the user terminal sent by the S-CSCF is triggered to the AS, The AS performs corresponding service processing according to the user terminal data downloaded during registration.

[0053] The user terminal data in the HSS includes the IFC. When the user terminal registers, the S-CSCF can download the IFC from the HSS. In this way, the S-CSCF can determine the service AS to process the user terminal according to the saved IFC of the user terminal, and Sending the first service request signaling triggers the determined AS.

Abstract

The invention discloses a service processing method for realizing disaster tolerance, which is applied in an IP multimedia subsystem (IMS) network comprising at least two service servers and used for solving the technical problem that the service process for identifying a disaster tolerance user terminal is complex in the conventional service processing for realizing disaster tolerance. The method comprises that: a service call control entity sends first session initiation protocol (SIP) service request signaling to a first service server for processing the user terminal service according to the stored initial filter criteria (IFC) of the user terminal; and when determining that the first service server fails, the service call control entity sends second SIP service request signaling with disaster tolerance user terminal identification to a second service server, so that the second service server performs corresponding disaster tolerance service processing according to the second SIP service request signaling.

Description

technical field [0001] The present invention relates to the technical field of IP multimedia subsystems, in particular to a method, system and device for implementing disaster recovery service processing. Background technique [0002] In order to meet the needs of multimedia communication, 3GPP introduced the IP Multimedia Subsystem (IMS, IP Multimedia Subsystem) on the basis of the original packet bearer network. IMS can not only provide traditional voice services to user terminals, but also provide rich multimedia services to user terminals. experience. figure 1 The basic architecture of the IMS network is described. [0003] Among them, the main network elements of the IMS include: a call control entity (CSCF, Call Session Control Function), a home subscriber server (HSS, Home Subscriber Server), and a service server (AS, Application Server). [0004] The CSCF is divided into three types: Serving-Call Session Control Function (S-CSCF), Interrogating-Call Session Control...
