ABSTRACT:
Methods and apparatus for use in reducing power consumption in battery-powered mobile communication devices in wireless local area networks (WLANs) are described. In one illustrative example, a mobile device in a WLAN is configured to normally refrain from receiving broadcast messages so that it may remain in a low power mode of operation. A network server is configured to convert broadcast messages into unicast messages for receipt by the mobile device only if the message or protocol type of the broadcast message is one in which the mobile device needs to process. As the mobile device is still configured to receive unicast messages, it will receive and decode such a unicast message and process the broadcast information within it accordingly. Advantageously, battery power is conserved at the mobile device.
