In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1, the technical program first execution mode provides a kind of method for switching network, comprises step:
S101, arranges different pieces of information type of service, and sets network bandwidth dependence weight factor threshold value corresponding to each data traffic types and 3G network base station signal strength threshold value.
In present embodiment, network bandwidth dependence weight factor can be defined as the transmitting power P under terminal 4G network
4G_TXthe maximum transmission power P of the terminal specified with 3GPP agreement
4G_MAXratio.It is larger, then higher to the requirement of the network bandwidth that the network bandwidth relies on weight factor numerical value.Described 3G network base station signal strength is the base station signal strength S that terminal obtains
3G_rssi.
Concrete, according to different data services, different data traffic types can be divided into.As current, the data service that user uses generally comprises the business such as web page browsing, game on line, Online Music, Online Video and point-to-point transmission.Classify according to the height of data service to the requirement of the network bandwidth, the network bandwidth corresponding to the described data service high to network bandwidth requirement relies on weight factor threshold value and is greater than the network bandwidth corresponding to the data service that network bandwidth requirement is low and relies on weight factor threshold value, and 3G network base station signal strength threshold value corresponding to the described data service high to network bandwidth requirement is greater than the 3G network base station signal strength threshold value corresponding to the data service that network bandwidth requirement is low.Five above-mentioned class data services to the requirement of the network bandwidth from low to high, define above-mentioned five kinds of types of service successively and are respectively I class business to V class business, and the network bandwidth dependence weight factor threshold value arranging described five kinds of data traffic types corresponding is β
