Abstract
A communication system implemented providing a service based on ProSe under the management of a network operator. Processing based on a discovery request procedure for discovering a proximity terminal is performed based on authentication of a server device operated by the network operator. In addition, the network operator updates the processing based on the discovery request procedure in accordance with a policy of the network operator.
Claims4
A User Equipment (UE) comprising:
- transmission/reception circuitry configured to:
- transmit, to a device equipped with a ProSe function, a first service authorization request message, to request authorization for the UE to be directly detected as a relay User Equipment (UE) by a proximity User Equipment (UE) positioned in proximity to the UE, or to request authorization for the UE to perform direct communication with the proximity UE;
- and
- receive, from the device equipped with the ProSe function, an authorization message for the first service authorization request message, wherein
- the authorization message includes a Relay Service Code and a timer value,
- the Relay Service Code is identification information of a connectivity service provided by the UE, and
- the timer value indicates a period of time during which a first service authorization for the connectivity service corresponding to the Relay Service Code is valid, and
- a controller configured to start a timer with the timer value included in the authorization message, in a case of receiving the timer value.
