Embodiment Construction

[0036]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.

[0037] The principle of the present invention is explained firstly. The present invention is essentially a solution for PDFE to perform proxy (Proxy) forwarding between BGCFE / PGCFE and BGFE / PGFE. In the process of IP network interworking, PDFE in RACS provides a unified interface for BGCFE / PGCFE to interact with BGFE / PGFE, forwards BGCFE / PGCFE control information downward to control BGFE / PGFE, and refers to the network provided by TRCFE The resource state imposes security, resource, and media effects on this control.

[0038] figure 2 A block diagram of an edge or packet gateway control system is shown.

[0039] exist figure 2 In the system shown, several network elements most related to IP network interworking are BGFE / PGFE, PDFE, TRCFE and BGCFE / PGCFE. The ...

Abstract

The invention relates to an edge or group gateway control method of next generation network, and a relative system, which can realize network communication of the edge or group gateway of NGN, under the effective control the network resource and local strategy, wherein PDFE is used as proxy between BGCFE / PGCFE and BGFE / PGFE; BGCFE / PGCFE, via the transferring of PDFE, sends the control information of IP network communication service to BGFE / PGFE; PDFE, based on the network resource condition and the preset local strategy provided by TRCFE, to process arbitration to obtain the relative decisions of IP network communication; based on said decision, distributing and / or modifying the transferred control information to be sent to BGFE / PGFE to be executed.

Description

technical field [0001] The invention relates to the next generation network technology, in particular to the edge or packet gateway control technology of the next generation network. Background technique [0002] With the development of traditional communication networks, the Internet and mobile communication networks, the integration of various networks is an inevitable trend. The next generation network (Next Generation Nerwork, referred to as "NGN") is based on Internet Protocol (Internet Protocol, referred to as "IP") packet exchange The network is the core network, the control and bearer are separated, and various access technologies coexist. The new generation network that integrates various existing networks can meet the needs of future broadband multimedia communications. [0003] NGN is a step towards packet switching in the traditional Public Switched Telephone Network ("PSTN" for short), which is mainly based on circuit switching. It carries all the services of th...
