Abstract

A communication method and a terminal are provided. The terminal may be equipped with circuitry that supports connecting to a wireless router using two or more frequency bands. The router may provide multiple networks using respective frequency bands. The terminal may be connected to the router a first frequency band. The method and terminal may facilitate establishment of a direct communication between the terminal and another terminal that is connected to the router using a network of a second frequency band. The another terminal may be equipped with a circuitry that only supports the second frequency band. The method and terminal describe determining a network that a target communication device is connected to, and connecting the terminal to that network. The terminal may then communicate with the target communication device through the network.
