FIELD: radio engineering, communication.
SUBSTANCE: terminal is indicated that a service providing channel which supports a high-level service is present in a current service area. A communication method includes steps of: storing, in an overlapping coverage area of a multi-RAT network, a service channel and a common broadcast control channel of a core network and notifying a secondary network to deactivate all or some of the common broadcast control channels; receiving a service request initiated by the terminal through the core network; notifying, when the core network is incapable of transferring the service request, the secondary network to allocate a secondary network service channel for the terminal.
EFFECT: saving power consumption in a network without incorrect scheduling of high-level services.
