Abstract
Processing based on a discovery request procedure for discovering a proximity terminal or being discovered is carried out 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. With this, provided is a communication system or the like in which a service based on ProSe is implemented under the management of a network operator.
Claims10
A communication control method performed by a User Equipment (UE), the communication control method comprising:
- in a service authorization procedure,
- requesting, to a Proximity-based Services (ProSe) function in a PLMN, authorization for direct discovery and/or direct communication;
- and
- receiving, from the ProSe function, an authorization message including a first timer value indicating for how long the authorization is valid, as a response to the request;
- starting a first timer based on the reception of the first timer value;
- in an announce request procedure, receiving a discovery response message including a ProSe Restricted Code and a second timer value corresponding to the ProSe Restricted Code from the ProSe function;
- starting a second timer based on the reception of the discovery response message;
- and
- transmitting an announcement message including the ProSe Restricted Code to a proximity UE,
- wherein
- the ProSe Restricted Code is used for direct discovery.
A communication control method performed by a Proximity-based Services (ProSe) function in a PLMN, the communication control method comprising:
- in a service authorization procedure,
- receiving, from a User Equipment (UE) a request of an authorization for direct discovery and/or direct communication;
- and
- transmitting, to the UE, an authorization message including a first timer value indicating for how long the authorization is valid, as a response to the request;
- and
- in an announce request procedure, transmitting a discovery response message including a ProSe Restricted Code and a second timer value corresponding to the ProSe Restricted Code to the UE,
- wherein
- the first timer value is used by the UE to start a first timer,
- the discovery response message is used by the UE to start a second timer,
- the ProSe Restricted Code is a code included in an announcement message which the UE transmits to a proximity UE, and
- the ProSe Restricted Code is used for direct discovery.
A User Equipment (UE) comprising:
- transmission and/or reception circuitry;
- and
- a controller,
- wherein
- the transmission and/or reception circuitry is configured to:
- in a service authorization procedure,
- request, to a Proximity-based Services (ProSe) function in a PLMN, authorization for direct discovery and/or direct communication;
- and
- receive, from the ProSe function, an authorization message including a first timer value indicating for how long the authorization is valid, as a response to the request,
- the controller is configured to start a first timer based on the reception of the first timer value,
- the transmission and/or reception circuitry is further configured to, in an announce request procedure, receive a discovery response message including a ProSe Restricted Code and a second timer value corresponding to the ProSe Restricted Code from the ProSe function,
- the controller is further configured to start a second timer based on the reception of the discovery response message,
- the transmission and/or reception circuitry is further configured to transmit an announcement message including the ProSe Restricted Code to a proximity UE, and
- the ProSe Restricted Code is used for direct discovery.
A Proximity-based Services (ProSe) function in a PLMN, the ProSe function comprising:
- transmission and/or reception circuitry configured to:
- in a service authorization procedure,
- receive, from a User Equipment (UE), a request of an authorization for direct discovery and/or direct communication;
- and
- transmit, to the UE, an authorization message including a first timer value indicating for how long the authorization is valid, as a response to the request;
- and
- in an announce request procedure, transmit a discovery response message including a ProSe Restricted Code and a second timer value corresponding to the ProSe Restricted Code to the UE,
- wherein
- the first timer value is used by the UE to start a first timer,
- the discovery response message is used by the UE to start a second timer,
- the ProSe Restricted Code is a code included in an announcement message which the UE transmits to a proximity UE, and
- the ProSe Restricted Code is used for direct discovery.
