Abstract: Power control in a spread-spectrum communication system takes place by determining origination power of a traffic channel based on a number of active demodulators and pilot channel signal quality (610). Once origination transmit power is determined and call origination takes place, the transmit power is reduced at a first rate when a time is less than a time for all active demodulators to be established (615), otherwise the transmit power is reduced at a second rate (621). After all active demodulators have been acquired power control takes place by receiving a Power Measurement Report Message (PMRM) or a Pilot Strength Measurement Message (PSMM), determining a signal quality metric existing at the remote unit based on the PMRM or PSMM, and adjusting transmit power based on the signal quality metric (645).

Abstract: An AMPS system facilitates reception and processing of a DS CDMA signal transmitted by a mobile station (125). The AMPS system provides an alternate path for the signal to be received by a DS CDMA receiver (506) system. The DS CDMA receiver system generates a signal compatible with the AMPS system, adjusts the generated signal to be proportional to the DS CDMA signal, and inputs the adjusted signal (510) into the AMPS system. The AMPS system then processes the adjusted signal for purposes of handoff of the mobile station (125) from the DS CDMA system to the AMPS system.

Abstract: A method of reducing an audio gap in a signal connection with a communication unit during handoff in a cellular communication system is provided. The method includes the steps of providing a temporary signal connection with the communication unit from a mobile switching center (MSC) of a source base site, through the source base site to a handoff target base site and establishing a trunk connection from the MSC of the source base site to a MSC of the target base site. The method further includes the step of interconnecting, at the target base site, the temporary signal connection, trunk connection, and communication unit; and re-routing the signal connection with the communication unit through the trunk connection.

Abstract: In a cellular radio-telephone system (50), a method of selecting an appropriate handoff target where the timing advance of a mobile has exceeded a timing advance threshold, the bit error rate has risen above a BER theshold, or the signal level has fallen below an RSSI threshold. The method includes discarding signal measurements of inappropriate base sites or base sites at excessive distance and performing calculations on the remaining measurements to select an appropriate handoff target.

Abstract: A method of selecting handover targets for a communication unit (40) exchanging a communicated signal through a serving base site (10-19) in a digital cellular system. The method uses timing a dvance to determine a relative distance of a communication unit (40) to the serving base site (10-19). The method comprises the steps of co mparing a timing advance value with a first threshold. The first threshold may be equal to a distance one and one-half times the radius of the serving cell. When the timing advance value exceeds the first threshold, a base site frequency list is modifie d to include base sites non-adjacent the serving base site. The identity of the base sites non-adjacent the serving base sites may be determined from the directionality of communication unit (40). The method further includes the step of selecting a handover target p roviding highest relative RRSI value to the communication unit (40) from the modified base site frequency list.
