In the power communication network, a network selection algorithm based on QoS guarantee of power service is proposed for the heterogeneous multi network mixed coexistence scenarios composed of 230MHz wireless private network, 1800MHz wireless private network, WLAN, WiMAX and 5G public network. Firstly, QoS parameters are selected and classified according to the network performance and power service demand index; Secondly, the subjective weight and objective weight are obtained respectively based on the analytic hierarchy process and the improved entropy weight method, and the subjective and objective weights are balanced by game theory; Finally, the multi-attribute decision theory is used to select wireless network access which can meet the QoS requirements of power service and the best performance. The simulation results show that the algorithm can effectively guarantee the QoS of power service, and realize the reasonable allocation of access network resources, balance the load and improve the utilization of resources.
