HYBRID POWER SAVE DELIVERY METHOD IN A WIRELESS LOCAL AREA NETWORK FOR REAL TIME COMMUNICATION

摘要

A mobile station establishes a schedule by which data is exchanged with an access point. The schedule allows the mobile station to use a low power mode (608) at times outside of the scheduled service periods. However, the mobile station may occasionally need to retrieve additional data from the access point, or transmit additional data to the access point, and so initiates an unscheduled service period to do so (614).
