Embodiment Construction

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly expressed, the present invention will be further described in detail below by taking UMTS network and WLAN network as examples, in conjunction with the accompanying drawings and specific embodiments. The present invention adopts following technical scheme to realize:

[0025] S1: Collect user information connected to the network to establish a user information matrix . User information includes: user occupied bandwidth, user service type and current access network type. access network j The number of users in , j=1,2 when there are 2 access networks. (The following uses two access networks as an example to illustrate, and the situation of multiple access networks is similar.) The establishment dimension is user information matrix , The element in is the bandwidth occupied by the corresponding user, or 0, for the first j network in the i The bandwidth o...

Abstract

The invention discloses a heterogeneous network vertical handover method based on network joint effect optimization and load balancing and belongs to the technical field of wireless communication. According to the invention, load balancing and network joint effect maximization between access networks are realized through optimized vertical handover and access network selection of users of a commonly covered area of heterogeneous access networks. A user information matrix is established, a network joint effect function is modeled, and under the conditions of giving access network load balancing, joint network user handover times and the like, optimized user vertical handover and network election schemes are obtained through maximizing the network joint effect.According to the heterogeneous integration realizing network, user vertical handover and network selection schemes of access network load, user handover times, user business characteristics and other factors are comprehensively considered, the maximization of network comprehensive benefits and the enhancement of quality of service (QoS) for users are realized.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to vertical switching technology in heterogeneous wireless networks. Background technique [0002] With the development of mobile communication and broadband wireless access technology and the increase of human demand for information communication, higher transmission rate, larger system capacity, and wider service coverage have become the mainstream trend and evolution goal of future mobile communication development. In order to meet the needs of different users, the next-generation wireless network will support the convergence and coexistence of multiple wireless access technologies, and user equipment with multi-mode interfaces can seamlessly switch between different access technologies to achieve business continuity and the best service experience . [0003] The user's handover between the base stations / access points of the heterogeneous converged network using different a...
