Network with a plurality of access networks and access and switching method

Abstract

The invention relates to a network with a plurality of access networks, which comprises a core network, a plurality of wireless access networks and terminals which are distributed in a coverage region of the wireless access networks, the coverage regions of a plurality of wireless access networks have overlapped regions, the center of the core network is provided with a switch strategy server, the terminals are provided with a switch strategy managing device, and the switch strategy managing device and the switch strategy server in the core network are wirelessly connected by any wireless access network. The invention further provides an access and switching method of the terminals in the network. The network and the method have the advantages that by setting the switch strategy server and carrying out the corresponding access and switching method, when various access networks are fused to build the network, a multimode terminal can select an optimum access network in the network overlapped regions, thus guaranteeing the loads of different access networks in the system to be balanced as much as possible, effectively utilizing the network capacity and resources and guaranteeing the quality of service when the terminals are used.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a network with multiple access networks and access and switching methods. Background technique [0002] When there are multiple wireless access networks in the network, when the terminal is in the superimposed coverage area of ​​the wireless access network and initially selects a network or roams between access networks, it often causes loads on different access networks because the selected network is inappropriate. Unevenness and the resulting bad user experience. [0003] Many access networks will be deployed in the operator's network system. Different access networks have different capabilities, and the number of users and user traffic accepted by different access networks will also vary. Unbalanced access network load means that when an access network bears more users and traffic than its load capacity, its load is overloaded and the network is congested, while other...
