IMS operation support system and method

Abstract

The invention relates to an IMS operation support system and a method. The method includes the generation flow of an IMS product and the activation flow of the IMS service; in the generation flow of the IMS product, the basic IMS service can be used to develop new IMS service; the method can provide service with different qualities for the products with different Qos grades and manage the IMS service orders related to the IMS products respectively so that different charging strategies are adopted for different IMS services. The invention provides a system frame of an available end-to-end IMS operation support system and the method, and proposes corresponding flows, aiming at the production generation, the service activation, the application and the charging process in the IMS operation process; according to each IMS service, the operation support system in the invention supports the Qos grade by grade mapping from the product to the network resources; thereby, the user is guaranteed to be supplied with high quality service from end to end.

Description

technical field [0001] The present invention relates to the field of IMS, in particular to an IMS operation support system and method. Background technique [0002] Telecom Operation Support System (OSS / BSS) is an integrated and information resource sharing support system in the operation process of telecom operators. It is mainly composed of billing, accounting, customer service, network management and other parts. management platform. [0003] IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) is a communication network that supports multimedia services, and it can meet customers' novel and diverse multimedia service requirements. At present, IMS is considered to be the core technology of the next generation network, and it is also an important way to solve the convergence of mobile network and fixed network and introduce differentiated services such as voice, data and video triple convergence. [0004] There is an essential difference between IMS and 2G systems. It ...

AI Technical Summary

Problems solved by technology

[0008] Therefore, the above characteristics will cause the IMS operation support system to be different from the operation support system of the existing 2G system

At present, the work on IMS operation support is still in the exploratory stage. The existing work can be roughly divided into two categories. One is based on the theoretical discussion given by some relevant specifications of the International Standards Organization 3GPP and 3GPP2; the other is for IMS operation. In-depth research has been carried out on a certain issue involved in the support, but so far these studies have not formed a complete IMS end-to-end (the entire life cycle from IMS product design, service generation, ordering, activation, and billing) The management of a series of coherent and orderly activities in the process) The operation support mechanism cannot effectively support the smooth development of the operator's 3G business based on the IMS network
