Method for implementing calling in the multimedia communication call control

Abstract

The invention disclosed a method which achieves call in a multimedia communication call control. This method includes: set user service information of rank in advance, obtain customer service information of rank related to call entities, according to user information of rank, defined users call processing priority, and call in accordance with established call processing priority. According to user information of rank, the invention brings up processing priority call methods in the third generation mobile communication multimedia communications call control, such as IP Multimedia Subsystem (IMS). The method provides a different priority call for different user service rank, and ensures the call-processing speed of the important network user's, improves customer satisfaction and loyalty.

Description

technical field [0001] The present invention relates to call technology in mobile communication system, especially a method for realizing call in multimedia communication call control. Background technique [0002] In the third generation (3G) mobile communication system, a multimedia communication technology based on IP technology has been proposed, wherein the IP Multimedia Subsystem (IMS) is a key technology of 3G mobile communication. [0003] In the operator's network, 80% of the profit comes from 20% of the important customers, and there are some emergency users with special needs. Therefore, the operator needs to improve the call level of these important users to ensure the call processing speed of the important users. , and at the same time ensure that important users can get priority access to resources when network resources are tight. However, the 3G call process has many steps, and there is a relatively large call delay. Therefore, operators urgently need a call...

AI Technical Summary

Problems solved by technology

However, the 3G call flow has many steps and there is relatively large call delay. Therefore, the operator urgently needs a call method that can correspond to different levels of call processing according to the service level of the user, so as to improve the call processing speed of important customers. In the case of network congestion or limited network resources, priority guarantees emergency calls and calls of users with high service levels

[0004] At present, in the IMS, only a simple emergency call method is proposed, and the specific implementation method is still under study; a call method that distinguishes different call levels of users according to the user service level (USL, User Service Level) has not been proposed, that is, Calls with different priorities cannot be provided for different user service levels
