摘要： The disclosure is directed to a mobile communication device that may receive wireless broadcast signals from a number of different base stations or transmitters. The device alternates its operation between a low-power mode and a higher-power mode to conserve battery power. The length of time the device remains in the sleep mode is its sleep interval. The sleep interval is a function of two components. One component is set by the wireless broadcast network and the other component is set by the carrier that provisions the mobile communications device. When the device awakens from the sleep mode, it can check the status of any notification messages. If there are any updates, then it will process them. If there are no updates, then it will return to the low-power mode.

摘要： A method and apparatus for delivering information to a dormant target mobile provides for sending the information when no dedicated traffic channel is established. In one embodiment, the method provides for sending the information in short data bursts. Therefore, the disclosed embodiments provide for a significant reduction in the actual total dormancy wakeup time by exchanging group call signaling even when the target mobiles are dormant and no traffic channel is active.

摘要： Methods and apparatus for sampling usage information from a pool of terminals in a data network. A method is provided to perform usage tracking in a data network. The method includes determining a targeted set of terminals from a pool of terminals on the data network, and transmitting tracking parameters to the pool of terminals. The method also includes receiving tracking data from the targeted set of terminals, and mapping the identities of the targeted set of terminals to device log identifiers. The method also includes associating the device log identifiers with the tracking data.

摘要： Methods and apparatus for bandwidth efficient transmission of usage information from a pool of terminals in a data network. A device includes transceiver logic to receive usage tracking and reporting parameters, wherein the usage tracking parameters identify events to be tracked and the reporting parameters identify reporting criteria for each event, scheduling logic to track the events based on the usage tracking parameters to produce a tracking log, reporting logic to process the tracking log based on the reporting parameters to produce a reporting log, and the transceiver logic to transmit the reporting log. A server includes processing logic to generate usage tracking parameters that identify events to be tracked and reporting parameters that identify reporting criteria for each event and a transceiver to transmit the usage tracking parameters and the reporting parameters to one or more terminals.
