  • Patent number: 7242938
    Abstract: A system and method for improved mobile assisted handoff in a digital cellular communication system that gives the mobile station the ability to synchronize to candidate base station transmissions in order to read the transmitted digital voice color code (DVCC) of the candidate station. This process is performed during the idle period between two designated time slots in a TDMA frame. The invention is an enhancement to the existing mobile assisted handoff procedures described in the existing IS-136 standard. The present invention improves on the IS-136 standard's use of received signal strength measurements in that it allows the mobile station to acquire and report information regarding the digital verification color code (DVCC) of the candidate base station channels. Since the DVCC uniquely identifies the cell site to which a channel belongs, it is used to distinguish the candidate base station channel from its co-channel interferers, allowing the network to make a more informed handoff decision.

  • Patent number: 6970698
    Abstract: A central host performs an automated method of updating multiple remote devices. In one embodiment, the host recognizes a predetermined download time and, in advance of the download time, transmits a calendar update to multiple remote devices. The calendar update includes the download time, and the remote devices may utilize the download time to set calendar reminders for entering an active state. Within a short time after reaching the download time, the host pushes download data to the remote devices by broadcasting the download data. In one aspect, the host may receive message acknowledgements from remote devices in response to a first calendar update, and the host may automatically transmit additional calendar updates to any remote devices that did not receive the first calendar update. Additional embodiments involve related methods and the terminal devices that receive the updates.
