Private network user and system and method for network intercommunication with QoS network

Abstract

The invention relates to a system and a method of intercommunication between private network users and business service quality guarantee network. The invention has the core that: in independent bearing control layer network, a bearing control layer entity and an application entity can acquire corresponding address (port) conversion information by an address conversion gateway NAPT-GW; and then, allocate resources for the private users correctly based on the address (port) conversion information. Therefore, the realization of the invention can facilitate all function entities to correctly process the delivery and conversion of the private addresses and reach the purpose of correct addressing and resources allocation, in order to effectively solve the problems of difficulty of correct end to end QoS resources allocation of the private network addresses used by users and no guarantee for end to end business QoS.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a system and a method for intercommunicating between a private network user and a service quality assurance network. Background technique [0002] With the continuous increase of Internet (Internet) scale, various network services emerge one after another, and advanced multimedia systems emerge in endlessly. Since real-time services are sensitive to characteristics such as network transmission delay and delay jitter, when there are high-bursty FTP (File Transfer Protocol) or HTTP (Hypertext Transfer Protocol) will be greatly affected; on the other hand, multimedia services take up a lot of bandwidth, so it is difficult for the key services to be guaranteed by the existing network to be reliably transmitted. [0003] Based on the above-mentioned status quo, various QoS (Quality of Service) technologies emerge as the times require. IETF has proposed many service mod...

Problems solved by technology

[0010] Usually, when a private network user interacts with an external user, it is necessary to convert the corresponding private network address into a public network address through the network address (port) translation function and then communicate with the external user. The network address (port) translation function is usually in the bearer layer Implemented in the gateway, so that the bearer control layer entity and the application layer entity cannot know the address translation process, and the consequence is that the QoS resource allocation of the service cannot be completed due to the inability to address correctly

[0011] It can be seen that due to the above reasons, at present, private network users who are only assigned private network addresses cannot communicate with the network that guarantees business service quality to ensure end-to-end service quality
