Abstract:
1. A method for performing a handover by a base station in a source radio access network, the method comprising: receiving, by the base station, a measurement report including measured signal quality, from a terminal; determining, by the base station, a handover initiation to a target radio access network, based on the measured signal quality; transmitting, by the base station, a handover request message to the target radio access network via a core network; receiving, by the base station, radio channel allocation information that is required if the terminal accesses the target radio access network, from the target radio access network via the core network; and transmitting, by the base station, the radio channel allocation information of the target radio access network, to the terminal, wherein the handover between the source radio access network and the target radio access network comprises an inter radio access technology (RAT) handover.
