Heterogeneous network accessing control method facing user quality of service (QoS) requirement and network load

Abstract

The invention provides a heterogeneous network accessing control method facing user quality of service (QoS) requirement and network load. The method aims at solving the problem of network choosing during uniform motion of a mobile terminal under a fusion framework of a universal mobile telecommunications system (UMTS), a wireless local area network (WLAN) and a wireless municipal area network (WiMAX); comprehensively takes limits including user moving speed, user QoS requirement, network business load, network coverage area and the like; performs preliminary election on the networks according to the moving speed of the users, if a plurality of candidate networks exist, then calculates eligibility factors and selects a network accessing with the largest user and network eligibility factor value according to QoS required by the users and provided by the network and network business load condition. The method can effectively avoid table tennis switching, meet user QoS requirement, utilize network resources as far as possible; simultaneously is simple and easy to achieve, and has good application prospect.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to a heterogeneous network access control method oriented to user QoS requirements and network load. Background technique [0002] With the rapid development of wireless communication technology, many new mobile communication networks such as wireless local area network WLAN, WiMAX, Wi-Fi, wireless personal area network WPAN, wireless Mesh network WMN, wireless sensor network WSN, Ad-hoc, 3G and B3G have emerged. Heterogeneous networks using different networking technologies. These networks are different in terms of coverage, data rate provided, supported mobility, and services suitable for transmission. They complement each other and coexist. Each radio access technology RAT has different characteristics in terms of capacity, coverage, supported mobility, and quality of service provided to users, but none of the networks can provide uniform coverage and continuous hi...

Problems solved by technology

[0004] At present, most of the relevant studies are only effective in one aspect, from the perspective of users or operators, without comprehensive consideration of user mobility, user QoS requirements, QoS provided by the network, and the impact of network load on the acceptance of users
