Abstract: Embodiments of the disclosure provide a method, device and computer readable medium for authentication. According to embodiments of the present disclosure, only the first terminal device in a group of terminal devices which requests to connect to a network needs to finish the whole authentication. Upon the first terminal device successfully accesses to the network, the remaining terminal devices in the same group can ignore the authentication. In this way, time for authentication is reduced and the calculation efforts related to authentication is reduced for a large number for terminal devices.

Abstract: One of the embodiments of the present invention relates to a method for controlling a D2D discovery process at a discovering user equipment. The method comprises determining by the discovering user equipment whether discovery information in a discovering message received from a discovered user equipment is sufficient for performing the D2D discovery process or not. In response to a positive result of the determination, the user equipment continues the discovery procedure without involvement of network node, at least by using the discovery information in the discovering message; in response to a negative result of the determination, the user equipment sends a request to a network node for assistance on further discovery information for performing the D2D discovery process, and then receives the further discovery information from the network node. Embodiments of the present invention also provide methods, apparatuses and computer program products.
