| 摘要 |
A system is disclosed in which a mobile communication device establishes device-to-device (D2D) communication with another mobile communication device, and searches for a communication network whilst engaged in the D2D communication. When it finds a communication network, the mobile communication device indicates that it is engaged in the D2D communication. The mobile communication device continues, or does not continue, the D2D communication based on an authorisation by the communication network. |
