Abstract: One kind of communication is referred to as device-to-device D2D communication. Misuse is an issue for this type of communication. For example a public safety network may permit D2D communication to operate in an area following a natural or other incident where the controlling network entity loses coverage. However this permission to allow D2D communication without the controlling entity can lead to users of D2D apparatus such as public safety communications devices configured for use in a first region being able to perform D2D communications in a second region in licensed bands that are illegal or not permitted. Furthermore, each device should be configured to setup an ad hoc network using D2D only in those areas where the licensed bands can be used legally by the device. Therefore, each device determines its position and blocks D2D operation when outside of a geographical area to which it was configured.
