Heterogeneous network switching management method and device in fixed-mobile convergence network environment

Abstract

The invention discloses a heterogeneous network switching management method in a fixed-mobile convergence network environment. Communication network field, the method comprises the following steps: acquiring network attribute information of each currently available network, a weighting weight set by a user terminal for each service, and a demand weight of each service for each network; the methodcomprises the steps of determining a current service in a user terminal; performing matrix operation based on the network attribute information, the weighting weight and the demand weight; determininga utility value of each network relative to the current service according to an operation result; sorting the determined utility values according to the determined utility values; determining a network suitable for the current service according to the sorting result; according to the method, the user terminal is switched to the target network according to the switching threshold, the switching threshold is determined according to the moving speed of the user terminal, and the mobile terminal cannot be switched back and forth when the network signal strength changes drastically, so that the ping-pong effect is effectively reduced.

Description

technical field [0001] The present invention relates to the field of communication networks, in particular to a heterogeneous network switching management method and device in a fixed-mobile convergence network environment. Background technique [0002] A heterogeneous network (Heterogeneous Network) is a network collection composed of computers, network devices and systems produced by different manufacturers, and in most cases runs on different protocols to support different functions or applications. With the development of communication network technology, the business requirements of mobile terminals are more diversified. A single type of network is not enough to fully meet the needs of mobile users in terms of high bandwidth, low latency, and coverage. Currently, heterogeneous networks are usually used to meet user needs. To meet the needs of different services, mobile terminals have the ability to access multiple networks. Therefore, handover of a mobile terminal in a...

Problems solved by technology

[0004] In the existing solution, in the heterogeneous network environment where the fixed-mobile network is integrated, the network switching is generally performed according to the signal strength of all the networks in the area where the mobile terminal is located. However, in this solution, when the mobile terminal enters a certain area , and the signal strength of several networks in this area changes drastically. At this time, the mobile terminal will switch back and forth in each network, thereby producing a ping-pong effect when switching networks. The ping-pong effect refers to that in a mobile communication system, if in a certain area The signal strength of the two base stations changes drastically, and the mobile terminal will switch back and forth between the two base stations.
