Method and system for realizing inter communication of telecommunication business between isomerized networks

Abstract

The system comprises two or more wideband isomery network, call control device for signaling intercommunication and cross-network call control, calling user possessing media port, called user possessing media port, and media intercommunication device for mapping media ports of cross-network and transmitting media flow, under control of call control device. The media intercommunication device possesses two kinds of media ports: one is relevant to media port of calling user, and the other is relevant to media port of called user. The device can select following operations: transmitting media flow from calling or called user directly; or processing media flow from calling or called user, then transmitting flow. The invented technical scheme realizes architecture of next network: separation between service and network, and separation between control and load as well as the invention realizes flexible way to build network.

Description

technical field [0001] The invention relates to the technical field of telecommunication, in particular to the realization of the intercommunication of telecommunication services among broadband heterogeneous networks. Background technique [0002] At present, in the new generation of IP (Internet Protocol, Internet Protocol) telephone network, based on the idea of ​​separation of control and bearer, the Media Gateway Controller (MGC for short) and the Media Gateway (MG for short) are separated from each other. Both logical and physical are completely separated. Access to various devices through different MGs, including PSTN (Public Switched Telephone Network, public switched telephone network), ISDN (Integrated Services Digital Net, integrated service digital network), PLMN (Public Land Mobil Net, public land mobile Communication network) and other traditional telephone equipment, and then use the MGC to uniformly control these MGs, so as to facilitate the introduction of ...

AI Technical Summary

Problems solved by technology

However, since the networks of the two operators have their own systems in terms of network planning and address allocation, IP users belonging to the two operators cannot communicate with each other, and call control equipment cannot establish calls across the two networks. The media between them cannot cross the network border and cannot achieve intercommunication

[0005] The current intercommunication method between IP data networks, such as the technical solutions provided in US Patent US6457061 (Method and apparatus for performing internet network address translation) and US Patent US6266707 (System and method for IP network address translation and IP filtering with dynamic address resolution) , which is more suitable for the one-way initiation method of client / server (Client / Server), which only converts the address of the IP header, and does not care about or understand the application layer information in the payload, so the telecommunications service cannot be guaranteed The transparency of intercommunication cannot solve the intercommunication requirements of end-to-end telecom services between broadband heterogeneous networks

At the same time, since the current various IP telephony protocols themselves only describe the methods of call control and media gateway control, resource management, service realization, etc., although the intercommunication model and method between the narrowband telephone network and the broadband telephone network are clearly defined, However, it does not provide a complete solution for the intercommunication of telecommunications services between broadband heterogeneous networks
