Multi-interface terminal with automatic network interface selection function and working method of multi-interface terminal

Abstract

The invention relates to a multi-interface terminal with an automatic network interface selection function and a working method of the multi-interface terminal. The multi-interface terminal is provided with a collecting module, an execution module, a structure improving and analyzing module, a decision-making module and an extra network quality feedback module. On the basis of a basic independent feedback loop, a novel network quality feedback loop is formed to feedback historical decision-making information and strategy execution result information; and the strategy execution results are associated with certain service requirements, so that reliability and effectiveness of network interface configuration strategies issued by networks can be judged. When facing access strategies of multiple available network interfaces, the multi-interface terminal is capable of objectively reporting actual properties of various network interfaces according to the historical decision-making information and the strategy execution result information, to provide a decision making basis; and further, contradictions between network strategies and service requirements can be coordinated, and quality of service of acquiring service requirements on a selected network interface is guaranteed.

Description

technical field [0001] The invention relates to a multi-interface terminal with a network interface autonomous selection function and a working method thereof, belonging to the technical field of computer and network communication. Background technique [0002] In recent years, the rapid development of computer communication technology and next-generation network technology has given birth to wireless communication systems of various technologies, providing users with a rich heterogeneous network access environment, including mobile communication networks (2G or 3G), wireless local area networks Wait. However, these access networks are usually specially designed for certain types of services or user requirements, so there are large differences in bandwidth, signal strength, transmission energy consumption, and data transmission rate. At the same time, the improvement, innovation and continuous maturity of computer hardware technology have also enabled more and more terminal...

However, due to the time-varying nature of the network status, the network configuration policy issued by the network can no longer truly reflect the current network status

In addition, multi-interface terminals will receive multiple network interface configuration policies issued by different networks. These policies reflect different network optimization strategies. As a result, multi-interface terminals cannot quickly and accurately select network communications that meet current business needs when selecting network interfaces. interface

[0010] Furthermore, the existing network interface selection method with feedback uses a basic autonomous feedback loop for network interface selection, which cannot meet the needs of reflecting the performance change trend of the network interface, resulting in the multi-interface terminal being unable to accurately select the optimal network interface.
