To Wireless Communication Systems and Methods

A method of controlling access to a device-to-device (D2D) communication service in a communication network, the method comprising:

• receiving a D2D discovery signal comprising data indicative of said D2D communication service;
• determining a verification state for the D2D communication service as one of a first verification state and a second, different, verification state, on the basis of said received D2D discovery signal, the first verification state being one in which said D2D communication service can be verified;
• and
• in the event that said D2D communication service is determined to be in the second verification state, transmitting data indicative of said D2D communication service for verification by the communication network.

Apparatus for use in controlling access to a device-to-device (D2D) communication service provided to a D2D device in a communication network, the apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus at least to perform:

• receive a first message comprising data indicative of said D2D communication service;
• verify whether said D2D communication service is authorised for said communication network;
• and
• transmit a second message comprising data indicative of the result of said verification for reception by said D2D device.

Apparatus for use in facilitating access to a device-to-device (D2D) communication service provided to a D2D device in a communication network, the apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus at least to perform:

• receive a first message comprising a first indication whether said D2D device is authorised for said communication network;
• receive a second message comprising a second indication whether said D2D communication service is authorised for said communication network;
• and
• transmit a third message for reception by the D2D device, the third message comprising a combination of the indication of the first and second indications.
