Abstract

The invention relates to a vertical network switching method based on self-adaptive weight adjustment. The vertical network switching method comprises the following steps: a terminal side monitors link quality of each network, and screens out an available network set by utilizing a judgment method based on received signal strength and threshold; the terminal integrates parameters obtained from the network side and selects alternative networks from the available network set through utilizing a load balancing mechanism based on network utility; and subjective and objective weight values ate adjusted through a self-adaptive weight adjustment algorithm, and the order of the alternative networks is calculated with a TOPSIS algorithm being combined, and a final switching decision is made. The vertical network switching method can help the mobile terminal to be accessed to the most appropriate network accurately and efficiently, thereby guaranteeing the available communication process of the mobile terminal in a low electric quantity mode to be longer, and improving the throughput of the whole system.

Description

technical field [0001] The invention relates to a heterogeneous fusion network system in the field of information technology, in particular to a vertical network switching method based on self-adaptive weight adjustment. Background technique [0002] With the rapid advancement of 3G networks, large-scale deployment of WLAN networks in hotspot areas, coupled with the widely used 2G networks, a ubiquitous wireless heterogeneous network has been formed. In a heterogeneous network environment, how to complete the vertical handover control process between multiple networks, so as to improve the utilization of wireless resources, is a highly concerned issue in the industry. [0003] At present, the vertical handover control technologies in the heterogeneous converged network (UMTS and WLAN) mainly include handover control methods in which the network is the main terminal as the auxiliary (MAHO) and the terminal is the main network as the auxiliary (NAHO). In the process, informat...
