Networking system for next generation network

Abstract

The invention discloses a networking system for next-generation network, comprising several network subregions, all connected by transregional network components, where these components only implementintercommunication between the application layers of all the network subregions and then implement their service intercommunication. The networking system comprises the below network subrgions: non-trust region, meaning the network the users can directly access to as well as the network with undetermined safety; trust region, meaning the service special network for the next-generation network; semi-trust region, the IP network region connected with the external data network by the firewall; operation maintaining region, an independent IP network, one side connected with the equipment at the operation maintaining server end and the other side connected with client ends; operation supporting network, a special network, managing the whole network equipment of the operator. The networking system has feasibility and implements the safety of access network and application server, implementing the intercommunication of all the network subregions.

Description

technical field [0001] The present invention relates to next generation network (NGN, Next Generation Network) networking, especially a next generation network networking system. Background technique [0002] NGN network is a new type of public telecommunication network based on IP technology. It can accommodate various forms of information. Under a unified management platform, it can realize the transmission and management of audio, video, and data signals. It has the following important features : [0003] Separation of bearer and control: Divide the next-generation network into three layers: media transmission, connection control, and application services. The network devices at each layer perform their own duties, and the network devices communicate through standard and open interfaces; [0004] Componentization of network equipment: Each layer of the next-generation network is divided into several types of network components according to their functions. The component...

AI Technical Summary

Problems solved by technology

[0028] Bandwidth embezzlement, through the open IP network port to realize the interconnection of private devices of users in different places, embezzling the bandwidth of the packet core network, causing the diversion of the operator's data service revenue and affecting the normal operation of the core network;

[0029] 2) Security issues of the application server

If the application server and the softswitch are connected to the same NGN network, the security of the softswitch will be reduced

In addition, many application services may be developed by a third party. If the security of the third-party software cannot be fully trusted, opening all NGN components in the NGN network to it also has security risks

[0031] 3) Intercommunication between different operators

[0032] Different operators build their own IP networks. Due to various reasons such as IP address allocation and commercial benefit allocation, they cannot directly communicate with each other in many cases.

In addition, there is no mutual trust relationship between NGN networks of different operators, and it is generally impossible to directly communicate with each other.

Therefore, the existing networking solution cannot solve the intercommunication problem between multiple operators

[0033] 4) Cross-regional network interoperability issues
