The present invention relates to a method of device-to-device communication controlled by a cellular mobile communication network. At the user equipment side, the user equipment receives a reconfiguration message from the base station for indicating a first IP service flow transported between a first user equipment and a second user equipment to be moved from a first interface to a second interface, the first interface and the second interface being respectively one of a cellular interface for an access to the cellular mobile communication network and a device-to-device interface for the device-to-device communication between the first user equipment and the second user equipment, the reconfiguration message including information for indicating the first IP service flow and information for indicating a second L2 protocol entity, and the second L2 protocol entity being used for transporting the first IP service flow via the second interface; and the user equipment de-associates a radio bearer carrying the first IP service flow from a first L2 protocol entity and associates the radio bearer with the second L2 protocol entity in response to the reconfiguration message, the first L2 protocol entity being used for transporting the first IP service flow via the first interface. |
