In order to achieve seamless handover of heterogeneous networks on the access network side, avoid frequent triggering of unnecessary handover by terminals, and ensure a balanced network load, the handover process of the network needs to strictly meet the performance indicators of the network status. For this reason, this paper considers the differences between wireless network technologies such as 5G and broadband and narrowband ad hoc networks for multi-link converged communication terminals, as well as the characteristics of terminal services, and proposes an adaptive switching method for power 5G converged communication networks. It realizes the optimization of switching efficiency, reduces the number of unnecessary switching frequently triggered by service terminals, and balances the network load at the same time. Guarantee the reliability of the power system in the event of emergency failures within the power communication network, and effectively support power deterministic services under the integrated network of power 5G multi-standard technology.
