Problems solved by technology

[0011] However, the method implemented through mobile IP requires the network to support mobile IP functions, which puts higher requirements on the existing IP network infrastructure and protocol upgrades
In addition, since the registration at the IP network layer and the broadcast diffusion delay of new routes are much greater than the handover delay index of the connection-oriented cellular phone system, such handover cannot well support the uninterrupted real-time requirements of

Embodiment Construction

[0057] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0058] The principle of the present invention is to realize seamless service switching by simultaneously establishing two service links of the old and new access networks. The network service switching system includes service control points, switching control points, terminals, etc. Firstly, the service control point needs to be able to process the switching requests of terminals, and implement the establishment of new service links and the removal of old service links. Secondly, by introducing The switching control point is used to centrally control and judge the switching conditions, and finally the mobile terminal is required to have the ability to establish another session while maintaining one session.

[0059] When the terminal moves and initiates a handover...

Abstract

This invention discloses a service switch system and its method for the network of the next generation, in which, a switch control point processes switch request and switch condition management, controls the switch and condition judgement in concentration, a service control point applies in setting up new session links and removing the original session link in the switch to be matched by the terminal and the access network node. In the process of switch, the terminal triggers switch request and the service control point reports the switch control point, which judges the switch condition and sends the switch instruction and the service control point sets up new links and removes the original one by signaling interaction to finish seamless switch.

Description

technical field [0001] The present invention relates to the next generation network technology, in particular to the service switching system and method of the next generation network. Background technique [0002] Next Generation Network ("NGN" for short) is a milestone in the history of telecommunications, marking the arrival of a new era of telecommunications networks. NGN has gradually taken the step towards packet switching in the traditional circuit-switching-based Public Switched Telephone Network ("PSTN" for short), and it carries all the original PSTN network. At the same time, a large amount of data transmission is offloaded to the Internet Protocol (Internet Protocol, referred to as "IP") network to reduce the load of the PSTN network, and many new and old services are added and enhanced with the new features of IP technology. It can be said that NGN is the product of the integration of PSTN voice network based on time division multiplexing and packet network bas...
