摘要： A method and apparatus for providing security in a group communication network provides for receiving an encryption key, encrypting media for transmission to a controller using the received encryption key, the encrypted media being directed to another communication device, and communicating the encrypted media to the controller. In one embodiment, the communicating includes wireless communication. The method and apparatus further provides for receiving encrypted media from a controller and blocking the encrypted media if the communication device is not enabled to receive encrypted-media transmission, or if the media is not encrypted based on an encryption key previously specified by the communication device. In another aspect, the communication device is a push-to-talk (PTT) device.

摘要： An apparatus and method for adaptively bundling media frames in a data packet for transmission in a wireless data network. When a wireless device is ready to transmit an audio communication, a message is sent from the wireless device to a communication server that checks for network usage conditions and adaptively determines a bundling factor for the audio communication. The bundling factor is transmitted to the wireless device, and the wireless device bundles media frames into a data packet according to the bundling factor.

摘要： A method and apparatus for joining a user to a call in a group communication network provides for receiving an indication from a user who wishes to initiate a group call and sending a request to a server to add the user to the group call if the group call is in progress. The method and apparatus also provides for receiving a response from the server indicating that the group call is in progress, alerting the user of being added to the group call, and receiving media from the server after a traffic channel is re-established. The method and apparatus also provides for a significant reduction in the actual total dormancy wakeup time and latency by exchanging group call signaling even when mobiles are dormant and no traffic channel is active.

摘要： A system and method for minimizing latency for direct group communications, such as push-to-talk (PTT) calls, among a group of wireless telecommunication devices on a wireless telecommunication network. The wireless telecommunication device has a dormant state without an open dedicated traffic channel for communications therefrom and an active state in which the wireless devices opens a dedicated traffic channel for an outgoing communication from the wireless telecommunication device, to include a direct communication stream. Either the wireless telecommunication device or an intermittent communication server for group communication streams can buffer the initial communication data of a group communication stream while the sending and/or receiving wireless telecommunication device changes from a dormant state to an active state with an open dedicated traffic channel.

摘要： Methods, devices, and systems for saving battery service life by preventing false alarms when a tracked asset is intentionally removed from a base safe-zone. A portable safe-zone beacon may create a portable safe-zone by broadcasting signals similar to a transmitter within a base safe-zone. A tracking device may employ a relatively low-power short-range radio transceiver to receive safe-zone broadcasts. If the tracking device does not detect safe-zone broadcasts before a timing counter expires, the tracking device may activate a high-power, long-range transceiver and transmit an alarm message via a wireless network. The tracking device may distinguish between transmissions of the portable safe-zone beacon and a transmitter of the base safe-zone and may operate differently based on being within different safe-zones. In response to receiving broadcasts, the tracking device may transmit response messages to the portable safe-zone beacon. In an embodiment, devices may relay data to and from the tracking device.

摘要： A system and method enable a wireless device to support simultaneously multiple push-to-talk (PTT) communications and interrupt certain PTT communication with higher priority ones. A user subscribes to multiple PTT communication groups and designates one of the groups as the primary group. The wireless device receives and plays PTT communications from the multiple PTT communication groups and interrupts playing of a PTT communication from a non-primary group if a PTT communication is received from the primary PTT communication group.
