Service selecting method, device and system thereof

Abstract

The embodiment of the invention discloses a service selecting method, a device and a system thereof. The service selecting method is applied in open service architecture and comprises the following steps: receiving a service call request message sent by an external application; acquiring strategic information corresponding to the service to be called according to service information; and selectinga service providing entity to call the service according to the strategic information. A service open entity is applied in the open service architecture and comprises a receiving module, an acquiringmodule and a selecting module. A strategic selecting entity is applied in the open service architecture and comprises a providing module. The service selecting system is applied in the open service architecture and comprises the service open entity and the strategic providing entity. The embodiment of the invention realizes that the proper service is selected for the external application according to the strategy, can more conveniently and accurately call the service of a communication network.

Description

technical field [0001] The present invention relates to communication technology, in particular to a service selection method, device and system. Background technique [0002] With the continuous development and maturity of the packet technology, the communication network is developing from the traditional telecommunication network based on circuit switching to the broadband telecommunication network based on packet switching. From circuit switching to soft interaction to the development of IP Multimedia Subsystem (IP Multimedia Subsystem, hereinafter referred to as: IMS), many excellent IT technologies have been absorbed, such as IP technology, distributed networking technology, Session Initiation Protocol (Session Initiation Protocol, hereinafter referred to as : SIP) technology and so on. Currently, the integration of IMS and Internet (Internet) has become the focus of research and development. Among them, Web Services is a technology that serves different platforms, an...

In this case, for the external application, there will be multiple identical service providers at the same time. When the external application calls a certain service, the OSA / Parlay architecture cannot select the appropriate service provider for the service called by the external application. Bring a lot of unnecessary troubles to users, and at the same time cannot guarantee the reliability and effectiveness of the service
