Method of handling device to device communication and related communication device

摘要

A method of handling device to device communication for a first user equipment (UE) in a wireless communication system includes establishing a Radio Resource Control (RRC) connection to a network of the wireless communication system; performing a proximity-based services (ProSe) communication with a second UE of the wireless communication system; and transmitting a first message to the network when the first UE detects a radio link failure in the ProSe communication; wherein the first message indicates the radio link failure to the network or requests changing to a UE-to-network communication mode from a ProSe communication mode.

1. A method of handling device to device communication for a first user equipment (UE) in a wireless communication system, the method comprising:
establishing a Radio Resource Control (RRC) connection to a network of the wireless communication system; performing a proximity-based services (ProSe) communication of direct data path type with a second UE of the wireless communication system; suspending the ProSe communication when a connection failure occurs in the RRC connection with the network; sending, to the second UE, a first signal indicating the second UE to suspend the ProSe communication when the connection failure occurs in the RRC connection with the network; and sending, to the second UE, a second signal indicating the second UE to resume the ProSe communication after the first UE resumes the ProSe communication.
