    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 while 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 authorization by the communication network.

    摘要: The present invention is to provide with the connection information on adjacent devices capable of connecting from a communication terminal. A connection information sharing server 200, communicatively connected with a communication terminal 10 and provided with a terminal location database 250 storing the location of devices in the storage unit, acquires the location information on the communication terminal 10, extracts adjacent devices 50 within a predefined distance from the terminal location database 250 based on the acquired location information, determines the connection methods available for connecting the communication terminal 10 with the adjacent devices 50, and transmits the determined connection method together with the information on the adjacent devices 50 to the communication terminal 10.

    摘要: Measures are provided for management of RRC for D2D communication. Such measures include setting a connected state of RRC for device(s) of a pair of devices. For the devices(s), both a D2D communication service between the pair of devices and a core network communication service between the device(s) and a core network entity are active. The setting enables radio resource management for the device(s) for the D2D communication service and the core network communication service. Termination of the core network communication service is detected for the device(s). A connection towards the core network entity is reconfigured for disabling the core network communication service of the device(s). The connected state of RRC is maintained for the devices(s) of the pair of devices, for which the device(s) only the device-to-device communication service is active. The maintaining enables radio resource management for the device(s) for the D2D communication service.
