    摘要： A packet mode (e.g. IP) group communication service layer is provided on top of a standard mainstream cellular radio network. Conceptually, the group communication layer includes a pair of basic logical entities, an application bridge and a call processing server (CPS). The bridge and the CPS run group service applications which communicate with group service application(s) in a mobile station MS over the IP connections provided by the radio network. The CPS is responsible for control plane management of group communications. The bridge is responsible for the real-time distribution of VoIP packets to the user terminals according to their group memberships over valid connections programmed by the CPS.

    摘要： The invention relates to dynamically creating talk groups in a communications system. A new dynamic group is created by a user who defines a group definition message in his subscriber station. This group definition message uniquely identifies the new group in the system, and can be distributed to the intended group members using the usual messaging facilities available in the specific communications system. The recipients of the group definition message can store the message in their subscriber stations for subsequent use. Thus, group creation and membership management are handled at user level without interacting with the system. The role of the system is restricted to establishing a means for communication in the group whenever there are users who have activated the group for communication.

    摘要： The invention relates to method applicable in a packet-switched cellular network for voice connections, by which method a new dedicated channel can be established quickly using the existing dedicated channel of the voice connection. The establishment of the new dedicated channel utilizes the previous dedicated channel the existence of which is extended by sending to at least the receiving terminals post-speech packets according to the invention. The post-speech packets produce a 2-second delay, approximately, which is sufficient to establish a new dedicated channel between terminals participating in a session.

    摘要： Point-to-multipoint communication on a communications network includes receiving a first downlink packet stream addressed to a first mobile recipient, checking whether the first stream is associated with group communication, which has already reserved downlink radio resources for a second downlink packet stream of a second mobile recipient located in the same radio cell as the first mobile recipient. If there are no existing radio resources, new radio resources are allocated for the first stream. If there are existing radio resources, no new radio resources are allocated but the first mobile recipient is instructed to receive the second stream over existing radio resources.
