Call processing method and system

Abstract

The invention is applicable to the field of communications and provides a call processing method and a system thereof. The call processing method of the invention comprises the steps that: the voice call continuity configuration information of a subscriber is collected and kept; when a call issued from a first domain by the subscriber is received, the configuration information is read according to a subscriber identifier; the configuration information is taken as a basis to judge whether the call needs to be continued to a second domain and the corresponding continuing is carried out. The embodiment of the invention pre-configures relevant VCC information by a CS domain or an IMS domain so as to ensure that gsmSCF can carry out the corresponding processing to the information in the subsequent call processing, which leads that the subscriber can optionally determine whether a certain calls need to be processed by the VCC and if the calls need not to be processed by the VCC, the faster continuing of the call from the subscriber can be realized, thereby the subscriber needs not to wait for a long time.

Description

technical field [0001] The invention belongs to the communication field, in particular to a call processing method and system. Background technique [0002] At present, 3G (Third Generation) technology has gradually matured and has been put into commercial use in many countries and regions around the world. The proposal of IP Multimedia Subsystem (Internet protocol Multimedia Subsystem, IMS) provides a solution for multimedia services in mobile networks. The 3G network is divided into different domains, including a circuit switched domain (Circuit Switched Domain, CS), a packet switched domain (Packet Switched Domain, PS) and an IMS domain. The CS domain uses circuit switching technology to provide voice and multimedia services, which is similar to the 2G system; the PS domain provides IP connectivity for users to access the Internet; the IMS domain uses Session Initiation Protocol (Session Initiation Protocol, SIP) as the main communication protocol. Users provide IP-base...

Problems solved by technology

[0012] The purpose of the embodiments of the present invention is to provide a call processing method, aiming at solving the problem existing in the prior art that the user cannot independently select whether the call needs to be processed by VCC, and all the calls are connected to the VCC application server in the IMS domain The problem that caused the user's call connection to take a long time and affect the negative experience

[0013] Another object of the embodiments of the present invention is to provide a call processing system, aiming at solving the problem existing in the prior art that users cannot independently choose whether their calls need to be processed by VCC, and all their calls are connected to the VCC in the IMS domain The application server causes the user to take a long time to connect the call and the problem of negative experience
