Problems solved by technology

In the design of multi-access selection methods, various factors need to be considered: signal strength, coverage, network load, service requirements, and user preferences; in addition, due to the differences of different access technologies, different wireless access networks affect resources The assigned factors are not easy to quantify and express uniformly, and it is difficult to make comparisons

Abstract

The invention discloses a user-based multi-access network selection method being used under a wireless heterogeneous network environment and provides a dynamic multi-access selection method which is combined with an object cost function and the analytic hierarchy process by starting from user interests and fully considering cost, QoS and stability of pre-access to a network. A network selection decision model is established by analyzing and judging influencing factors; furthermore, the method has the advantages of the multi-factor-based network selection method, and can correctly and effectively carry out network selection and be conveniently realized in a user terminal.

Description

technical field The invention relates to wireless resource management technology in heterogeneous environment in mobile communication, in particular to an access selection method in mobile communication. Background technique Since the second-generation mobile communication system represented by GSM (Global System for Mobile Communications) began to expand rapidly around the world in the 1980s, CDMA (Code Division Multiple Access) systems, IEEE802.11a / bWLAN (Wireless Local Area Networks), Many different types of wireless access systems (Radio Access System), such as Bluetooth (Bluetooth) and WiBro (wireless Internet access), have also sprung up like mushrooms after rain. Since these wireless access systems are specially designed for certain types of services and user groups, in terms of wireless access technology, coverage, available bandwidth, tariff level, support for user mobility and service quality assurance, etc. There are differences. The next generation wireless com...
