Abstract

The invention provides a method for access network selection according to real-time network conditions, and relates to a network selection optimization method for a heterogeneous network. The heterogeneous network is a network comprising a cellular network and a WLAN, the cellular network is a first network, and the WLAN is a second network. When the service of the first network to which equipment joins is not satisfactory, according to a network list provided by ANDSF and RAN Rules, the equipment offloads the traffic from a top network, and when the load of the first network is too high, or the first network is congested, the equipment can timely switch to the second network. Through adoption of the method, a shortcoming that a better network cannot be selected timely is improved, the network performance is improved, and the resource utilization is maximized.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a network selection optimization method for a heterogeneous network. Background technique [0002] With the development of wireless communication technology, in order to meet the requirements of users for network throughput and network speed, the emergence of heterogeneous networks has solved the problem of high load and decreased throughput of a single network, but the problem of network selection for heterogeneous networks has always been It is a topic that people are constantly exploring. Taking the heterogeneous network scenario where WLAN and LTE systems coexist as an example, the current network selection method is usually based on ANDSF and RANRules, and the user evaluates the quality of the received signal in the two networks separately, combined with the network load, backhaul bandwidth and other network conditions. The choice of access network or the decision of...
