FLOOR CONTROL IN POC TELECOMMUNICATION SYSTEM

摘要

The present invention relates to a method for floor control in a push-to-talk over cellular (PoC) communication system. The present invention also relates to a PoC telecommunication system for floor control and a PoC Client (PoC-C) and a PoC Server (PoC-S) in the PoC system enabling said floor control. The system comprises at least one first PoC client (PoC-C A) in a first user equipment and a first PoC server (PoC-S (C)) performing a controlling function. A floor control command is sent to the PoC-S (C) from the PoC-C A that includes a request or a release of a floor access. The PoC- C A is allowed to send 6A-6D on the floor one talk burst in the system at least to a second PoC client (PoC-C B) installed in a second user equipment. The floor control command is sent for the purpose of the PoC-C A requesting or releasing a floor on which the talk burst can be sent. When the PoC-S (C) decides to grant a floor access it sends 4A,4B a talk burst confirmation to the PoC-C A and informs about the acknowledgement of said request. The first PoC client (PoC-C A) then sends 6A-6D the burst including voice media in the communication system at least to the second PoC client (PoC-C B). What particularly characterizes the method according to the present invention is that the first PoC client includes the floor control command into at least one compact floor control data packet which also comprises the voice media. The first PoC client further sends the compact floor control data packet to the first PoC server (PoC-S (C)) following an activation 1 or deactivation 7 of the first PoC client on the first user equipment.
