    摘要: The present invention is a system and method for providing group communication services in an existing communication system. Group communications are enabled by installing a communications manager in a data network such as the Internet. The communications manager acts as a configurable switch, allowing communications from any group member to be transmitted to all other group members. The communications processed by the communications manager take the form of data packets, suitable for transmission over the data network. The data packets are generated by communication devices operating within the communication system. The use of the communications manager further allows users of other communication systems and devices to participate in group communications with each other.

    摘要: An apparatus and method for providing secure end-to-end communications over a wireless network. Audio transmissions are encrypted at the sending wireless device before being transmitted over the wireless network. Encrypted audio messages received from the wireless network are decrypted at the receiving wireless device, and then played to a user. The encryption and decryption are performed by a memory resident applet at the wireless device, and the user may selectively download a newer version of an applet with a different encryption algorithm from a server.

    摘要: A method and apparatus for reducing transmission overhead in a wireless communication system. In one embodiment, the apparatus is directed to a communication device comprising a processor for transmitting a data origination message, the data origination message initiating a data communication with a receiving station. Information needed to construct datagrams are also transmitted by the apparatus to the receiving station. The receiving station receives the data origination message and the information needed to construct datagrams and configures a packet data generator for sending datagrams to a destination device. Data network header information is constructed from information provided by the information needed to construct datagrams.

    摘要: A method and apparatus for providing an efficient dormant mode for push-to-talk communication devices in a group communication network provides for determining whether the net has been inactive for a predetermined first time period and, if so, causing each member of the net to enter a control-hold mode, wherein each member of the net maintains its dedicated traffic channel. The method further includes the steps of determining whether each member of the net has been in the control-hold mode for a predetermined second time period and, if so, causing each member of the net to enter a dormant mode, wherein each member of the net releases its dedicated traffic channel. The method and apparatus further provides for causing each member of the net to cache its service configuration state before entering the dormant mode.

    摘要: A method and apparatus for reducing latency in a group communication network provides for a significant reduction in the actual total dormancy wakeup time and the PTT latency by exchanging group call signaling even when mobiles are dormant and no traffic channel is active. The method and apparatus provides for exchanging the group call signaling through the use of the short data burst (SDB) message signaling. The method and apparatus provides for reestablishing dedicated traffic channels for the talker mobile and the dormant listener mobiles advantageously in parallel.
