Abstract
Communication methods and related devices are described to manage an air interface resource through a common radio resource control (RRC) connection of different cards in a multi-SIM multi-standby terminal and implement service concurrency of the multi-SIM multi-standby terminal. In an example method, after setting up an RRC connection for communication between a first network and a terminal device, an access network device receives, from the terminal device through the RRC connection, a registration request message that requests to register with a second network, and sends the registration request message to a core network device in the corresponding second network. Then, after the access network device receives a registration response message from the core network device, the access network device sends the registration response message to the terminal device, to complete a process in which the terminal device registers with the second network.
