A method and apparatus provides for delivering information to an idle mobile station in a group communication network includes delivering the information to the mobile station in special form, e.g., short data burst (SDB) form, if the information is smaller than a predetermined size limit. In one embodiment, the method and apparatus provides for encapsulating the information inside a frame, forwarding the frame to a server for delivery to the mobile station, and causing the server to extract the information from the frame and deliver the information to the mobile station on a forward common channel. In one embodiment, the method and apparatus provides for receiving information for delivery to the mobile station, the information being tagged for delivery on a forward common channel, and delivering the information to the mobile station on the forward common channel. In one aspect, the method delivers the information when the mobile station is in idle state with no traffic channel.

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 re-establishing dedicated traffic channels for the talker mobile and the dormant listener mobiles advantageously in parallel.

A method and apparatus for reducing perceived latency in a group communication network provides for receiving a request from a user of a communication device wishing to initiate a group call, receiving media from the user before completely processing the request, and buffering the received media for later transmission.
摘要:
A method and apparatus for reducing dormant-wakeup latency in a group communication network provides for a significant reduction in the actual total dormant-wakeup time and the PTT latency perceived by the talker through caching the network-initiated wakeup triggers destined for target listeners, and delivering a wakeup trigger to a target mobile station as soon as the target mobile station has re-established its traffic channel.
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.

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.

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.
