Abstract: A method of reducing power consumption in a communication device includes a step of acquiring a signal on a common pilot channel of a radio communication system. A next step includes detecting predetermined bits in the signal on the common pilot channel indicating activity on paging channels of the radio communication system. When no paging channel activity is indicated in the second step, a last step includes powering down portions of the electrical circuitry of the communication device so as to reduce power consumption, and when paging channel activity is indicated in the second step, a next step includes powering up portions of the electrical circuitry of the communication device such that those paging channels indicating activity are monitored by the communication device.

Abstract: The telephone includes a pilot circuit monitoring subscriber search activity to save power when no such activity is taking place. The power saving system comprises a first stage of collecting a signal from a communication base on a pilot channel. The next stage includes the detection of predetermined bits within the signal on the common pilot channel which indicate the occurrence of a search for specific users on the communication system. When no user search activity is detected within this second stage, the final stage operates to put certain electrical circuits of the mobile telephone into a low power standby mode, thereby reducing overall power consumption. When activity is detected in the user search component of the received signal, the telephone circuits are switched back to full power to enable receipt of an incoming call.

Abstract: A method (20,200) and apparatus (10) for detecting and identifying spectrum opportunities, including the steps of communicating a location of at least one node (12) to at least one base station (14) (24), transmitting a list of at least one channel from the at least one base station (14) to the at least one node (12) (26), and sensing the at least one channel from the list by the at least one node (12) (34). The method (20,200) also includes the steps of determining if the at least one channel is in use, and if the at least one channel is in use, determining the user of the at least one channel that is in use (38).
