Abstract

A method and apparatus for reducing power consumed by mobile wireless units, such as personal communications systems or wireless PBX telephones, by reducing the frequency with which various circuits within the units are fully energized. During on-going voice communications between a base station and a wireless unit, the wireless unit reduces the frequency of its references to a control channel and may eliminate such references altogether. In addition, while idle, the wireless units may not attempt to reference the control channel during all occurrences of the control channel, reducing both power consumption and the possibility of collisions with other wireless units in attempting to access the control channel.
