A service-based multi-access network selection system and method in a heterogeneous wireless network

Abstract

The invention, which belongs to the technical field of communcaition, relates to a service-based multi-access network selection system and method in a heterogeneous wireless network. The system comprises a service flow requirement analysis module, a terminal information processing module, a network port data processing module and a service-based multi-access network selection decision module. The service flow requirement analysis module, the terminal information processing module, and the network port data processing module carry out collection or processing on basic data and transmit the processed data to the service-based multi-access network selection decision module; the service-based multi-access network selection decision module carries out corresponding determination and decision making by using a service-based multi-access network selection method, provided by the invention, in the heterogeneous wireless network and informs a wireless network interface of a decision result. According to the service-based multi-access network selection system and method in a heterogeneous wireless network, rapid and reliable parallel transmission of services can be realized; and the throughput capacity of the terminal and the utilization rate of all network resources are improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a service-based multi-access network selection system and method in a heterogeneous wireless network. Background technique [0002] With the development of communication technology, various wireless access technologies have emerged as the times require. Since these access technologies are different in coverage, bandwidth, and application scenarios, it is difficult to replace each other. In addition, with the rapid development of mobile services, a single network cannot meet the diversified and personalized development needs of services. Therefore, the integration of heterogeneous wireless networks is an inevitable trend and trend of future wireless network development. At the same time, the integration of heterogeneous wireless networks promotes the development of mobile terminals, enabling existing multi-mode terminals to support multiple communication systems at the same t...
