  • Patent number: 7257421
    Abstract: A communication system controls a cell reselection mode of a mobile station while the mobile station resides in a cell by determining a cell reselection mode of the mobile station, determining whether the mobile station is experiencing a change in radio frequency (RF) conditions, and when the mobile station is experiencing a change in RF conditions, instructing the mobile station to change a cell reselection mode used by the mobile station.

  • Publication number: 20060146744
    Abstract: In the present technique of a data transmission management, responsive to a reselection during a data transmission, a determination (314, 514) is made as to whether remaining untransmitted data blocks of the data transmission can be sent within an allowed transmission time. If so, the remaining untransmitted data blocks are transmitted (318, 518) to complete the data transmission. If, however, the remaining untransmitted data blocks cannot be transmitted within the allowed transmission time, the communication link is terminated (312, 510) to stop the downlink data transmission with a serving station.

  • Publication number: 20060068792
    Abstract: A system and method of determined selected operating parameters for a mobile unit (102). Mobile device performance information is monitored in at least one neighboring cell (108, 110, or 112) and mobile device performance information is monitored in a serving cell (106). Selected operating parameters of a mobile device (102) are determined based upon the mobile device performance information in the at least one neighboring cell (108, 110, or 112) and the mobile device performance information in the serving cell (106).

  • Patent number: 6990342
    Abstract: Transferring communication within a communication system occurs as follows: during communication with a serving base station, in order to shorten the duration before downlink data can be initiated to a remote unit that has performed cell reselection, an automatic downlink procedure is executed. The auto downlink procedure transfers remote unit related information to a scheduler for appropriate allocation of air interface resources for a remote unit that recently has undergone a cell reselection procedure. When the remote unit reestablishes itself in a target cell, the source packet control unit determines that the cell reselection was successful and selectively transfers radio access capability information to the target packet control unit. The target packet control unit immediately is able to transfer downlink data arriving from the serving GPRS support node to the remote unit without first establishing a downlink temporary block flow, thereby significantly reducing the time required for cell reselection.

  • Publication number: 20040176093
    Abstract: A wireless infrastructure includes a source base transceiver station (BTS) that provides communication services to a mobile station (MS), a target BTS, a packet control unit (PCU) in communication with the target BTS, and a Serving GPRS Support Node (SGSN) in communication with the PCU. The PCU detects a cell reselection by the MS and initiates a cell reselection procedure in the infrastructure without first receiving a FLUSH_LL message from the SGSN based on messages received by the PCU from the MS via the target BTS and a record of the MS maintained by, or in association with, the PCU.
