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

Abstract

The invention relates to a system and method for intercommunication between a private network user and a service quality assurance network. The core of the present invention is to enable the bearer control layer entity and the application layer entity to obtain the corresponding address (port) translation information through the address translation gateway NAPT-GW in the independent bearer control layer network, and then based on the address (port) translation information In this way, correct resource allocation can be performed for private network users. Therefore, the implementation of the present invention can enable each functional entity to correctly handle the transmission and conversion of the private address, and achieve the purpose of correct addressing and resource allocation. Therefore, it effectively solves the problem that the user cannot correctly complete the end-to-end QoS resource allocation and cannot guarantee the end-to-end service QoS by using the private network address.

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
