Abstract:
Methods and apparatus, including computer program products, are provided for D2D handovers. The method may include sending to a target base station a handover request message including a proposed common identifier for a device-to-device pair and a proposed allocation of radio resources for the device-to-device pair; receiving, from the target base station in response to the handover request message, a handover request reply message including a confirmation of the proposed allocation and of the proposed common identifier; sending to a first device of the device-to-device pair a handover command including the proposed allocation and the proposed common identifier; receiving, from a second device of the device-to-device pair, a measurement report representative of the target base station; and determining whether to initiate a handover of the second device to the target base station, wherein when the handover is initiated, the first device of the device-to-device pair and the second device of the device-to-device pair are handed over to the target base station. Related apparatus, systems, methods, and articles are also described.
