Abstract: An electronic apparatus used on a user equipment side includes a processing circuit. The processing circuit is configured to select the mode of the relay discovery process of user equipment. In the relay discovery process, the mode determines whether the user equipment, when acting as a relay device, discovers a relayed device or is discovered by a relayed device, or whether the user equipment, when acting as a relayed device, discovers a relay device or is discovered by a relay device. After a connection is established between the relay device and the relayed device, the relayed device obtains a communication service via the relay device by means of a proximity service communication. The processing circuit is further configured to perform control, so that the user equipment carries out the relay discovery process according to the selected mode.
