Abstract (en)
[origin: WO2005122470A1] A communication system including a first and second user equipment in communication over a shared floor and a server means for managing the shared floor. According to the system, the server means is arranged to detect an anonymity request from the first user equipment and, responsive to the anonymity request, to prevent the second user equipment from identifying the first user equipment from user plane messages transmitted from the first user equipment to the second user equipment. The shared floor may relate to a push-to-talk over cellular (PoC) service.
