Abstract
Modem throughput across a cellular mobile telephone network is increased by controlling the response of the modem to blank and burst orders. In the case of a power control order, the modem may be made aware of the fact that the channel has not changed. Significant performance gain in terms of channel throughput can then be achieved by avoiding a lengthy retraining procedure. The modem operation may be suspended during the blank and burst order and enabled after the blank and burst order, avoiding an unnecessary retrain procedure during the blanking period. In the case of a handoff, the modem may be directed to immediately perform a retrain procedure rather than wait for the long blanking period to be detected by the modem or the link access procedure.
