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: A soft handoff operation is provided for a first signal transmitted according to a first communication standard (IS-95B) and a second signal transmitted according to a second communication standard (IS-95C). A mobile station (MS) (204) receives the first signal, detects a pilot signal, measures pilot signal strength, and transmits a pilot strength measurement message. When the MS fails to receive a handoff direction message after transmitting the pilot strength message, the MS searches for a detecting presence of a broadcast control channel (BCCH) associated with a type IS-95C cell site (202) and measures a carrier-to-interference ratio of the BCCH. The MS compares the carrier-to-interference ratio to a threshold, and when the ratio is above the threshold, initiates a second communication according to the IS-95C standard, thus initiating a soft handoff operation and allowing cell sites (202, 203) to transmit information according to the IS-95C and IS-95B standards, respectively.

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.
