  • Method for managing communication sessions
    Patent number: 7203509
    Abstract: A method for managing communication sessions in a packet-oriented communication system, consisting of a central control unit and a plurality of mobile stations, which can be interconnected via the central control unit. To achieve this, a communication session is established between mobile stations that are assigned to a first communication group. Session priorities are then defined for a first mobile station of the first communication group, said station being in addition assigned to at least a second communications group. Finally the session priorities are transmitted to the central control unit. A second communication session is also established between those mobile stations that are assigned to the second communication group(s), including the first mobile station. Both the first and the second communication session are established via the central control unit, in such a way that the latter can manage the first mobile station in both communication sessions according to the transmitted session priorities.
