Method and system for multiple application servers sharing sh interface service identifier, hss

Abstract

The invention discloses a method for sharing Sh interface service identifiers by multiple application servers (AS). The method comprises the following steps that: a home subscriber server (HSS) receives a service-indication subscription request of each AS, stores the service-indication subscription request and sends service-indication information subscribed by the AS to the AS if the service-indication information subscribed by the AS exists. The invention also discloses a system for sharing the Sh interface service identifiers by multiple ASs and the HSS. According to the invention, the service-indication information subscribed by the Ass sharing the Sh interface is kept to be consistent, so that the service consistency of the ASs is well realized, and the quality of service of the system is improved.

Description

technical field [0001] The present invention relates to a technology for multiple application servers (AS, Application Server) to share service identifiers, in particular to a method and system for multiple application servers in an Internet Protocol Multimedia Subsystem (IMS, IP Multimedia Subsystem) to share Sh interface service identifiers , and Home Subscriber Server (HSS, Home Subscriber Server). Background technique [0002] The Internet Protocol Multimedia Subsystem (IMS, IP Multimedia Subsystem) is the main direction of the development of future multimedia communication, and it is also the most important component of the next generation network. IMS is a subsystem that supports IP multimedia services proposed by the Third Generation Partnership Project (3GPP, The Third Generation Partnership Project). Its notable feature is that it adopts the Session Initial Protocol (SIP, Session Initial Protocol) It can have various capabilities such as separation of control funct...

[0014] figure 2 Schematic diagram of the structure of the IMS system in the case of AS Pool networking, such as figure 2 As shown, in the case of AS Pool networking, multiple ASs are interconnected with one HSS, and all user data is enabled through a pair of ASs that are mutually disaster-tolerant. Other ASs are only responsible for implementing specific services and do not activate users. Data, for user data that cannot be stored by HSS, is stored on the AS used to activate the service. In this networking mode, after the BOSS activates the information specified by the service instruction, the user registers on AS3 and AS4, and AS3 and AS4 download the The information specified by the service instruction, and subscribed to the relevant changes; when the BOSS deletes the service again, the HSS notifies the AS to delete the service, and then deletes the subscription specified by each AS on the HSS for the service instruction; similar to the multi-AS situation, when the BOSS increases again After the information specified by the service instruction, since AS3 and AS4 do not subscribe to the service instruction on the HSS, the HSS will not notify AS3 and AS4 of the service change, then AS3 or AS4 cannot implement the service corresponding to the service instruction
