Problems solved by technology

The above UMA scheme has brought a large amount of data traffic to the GSM/GPRS core network, causing the main entities of the existing GSM/GPRS network, such as the mobile switching center server (MSC), serving GPRS support node (SGSN) and gateway GPRS support node ( GGSN), etc., must be expanded or even replaced to meet additional requirements, which offsets the advantages of the UMA solution to the existing GSM/GPRS network with less changes, resulting in a higher cost than the IMS solution in the case of large-scale user de

Example Embodiment

[0068] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0069] Fig. 1 is a schematic diagram of the structure of a multi-mode terminal provided by the present invention. As shown in FIG. 1, the terminal includes a configuration management unit 100, a call and switching unit 110, and a network communication unit 120. Among them, the configuration management unit 100 is used to save the configuration information of each module, and is connected to all other modules for information exchange; the network communication unit 120 determines the switching time according to the detected communication network information and switching strategy, and informs the call and switching of the switching message Unit 110: After receiving the switching message from the network communication unit 120, the call and switching unit 110 sends...

Abstract

The present invention provides a terminal and method that realizes the seamlessly switch between the IMS network domain and the CS domain network, It could conducted real-time detection of the network condition and switch the communication network when the switching strategy is satisfied. So the continuous conversation during the switch could be ensured. It would also provide technical support to IMS domain network that orients at a variety of access technologies and uses SIP as a session control protocol, and provide the effective technical guarantee for the further development of FMC.

Description

technical field [0001] The invention relates to communication network switching technology, in particular to a terminal and a method for realizing seamless switching between different communication networks. Background technique [0002] With the development of communication technology, it has become the direction of development to realize the integration of communication services and communication networks through various common protocols. The purpose is to make communication more convenient for users. [0003] The IP Multimedia Subsystem (IMS) for multiple access technologies, IP-based multimedia service and session control core network, has both the convergence point "IP" for technology convergence and the convergence point "Multimedia" for service convergence, and is suitable for Fixed-Mobile Convergence (FMC), thus becoming the core of next-generation convergence technology. IMS is a public platform that supports various converged services defined and developed by mult...
