Abstract

The invention discloses a 4G and 5G multimode terminal network selection method based on a service type. The method comprises the following steps: calculating wireless resource utilization rates U4G and U5G of 4G and 5G current networks; calculating network radio resource utilization rates U4G-B and U5G-B after B radio resources are pre-allocated to the 4G and 5G networks; calculating normalized equivalent values FA4G-m and FA5G-m of factors m influencing network selection of 4G and 5G networks; calculating network selection preference factors S4G-i and S5G-i of the 4G and 5G networks; calculating network resource matching factors F4G and F5G of the 4G network and the 5G network; and calculating a 4G / 5G multimode terminal network bearer selection factor F, and selecting a network accordingto a calculation result. According to the invention, when 4G and 5G multimode terminal network bearing selection is carried out, the resource utilization rate of the existing network can be fully considered, and the network bearing selection based on service characteristics is realized by combining the performance of the network and the bearing capability of different services.
