摘要： A method, system, and apparatus for managing spreading codes used in communication over a radio frequency air interface. When a radio access network (RAN) is to assign a spreading code to a mobile station in the coverage area, the RAN may determine which mobile station currently having an assigned traffic channel in the coverage area has a highest forward-link signal quality, and the RAN may select a spreading code based on the spreading code of that determined mobile station's assigned traffic channel. For instance, the RAN may select a spreading code that is quasi-orthogonal to the spreading code of the determined mobile station's assigned traffic channel.

摘要： A method and system is disclosed for maintaining codec consistency across a communication session. When a communication session is set up for an access terminal (AT) operating in a wireless communication system, a network device, such a base station, can determine a coding rate to assign the AT for its air interface in a manner that accounts for network capacity variations spatially and/or temporally across the session. If the requested communication session is determined to be with a landline device, then a higher coding rate may be used than might otherwise be selected. If the requested session is with another AT, then a coding rate that best accommodates the air interfaces of both ATs may be used. If the AT is predicted to handoff to multiple sectors during the session, then a coding rate that best accommodates the air interfaces of all the predicted handoff sectors may be used.

摘要： Methods and systems for adjusting a transmit power of a forward link or reverse link signal make use of variable adjustment parameters. The wireless signal is received to obtain a received signal. An observed signal-to-noise ratio (SNR) and an observed frame error rate (FER) for the received signal are determined. In an outer loop process, an adjustment increment is selected based on how much the observed FER differs from the target FER, and the target SNR is adjusted by the adjustment increment. In an inner loop process, a power adjustment command is selected based on a comparison between the observed SNR and a target SNR. The power adjustment command instructs the transmitter of the wireless signal to either increase or decrease the transmit power of the wireless signal. The power adjustment increment may also depend on the observed FER.

摘要： A mobile station measures a pseudonoise (PN) offset and a signal strength of a spread spectrum signal transmitted by a given sector of a spread spectrum communication system. The measured PN offset differs from a nominal PN offset of the given sector. The mobile station transmits a measurement message that includes the measured PN offset and the measured signal strength. The spread spectrum communication system receives the measurement message and determines a location associated with the mobile station (e.g., based on location coordinates included in the measurement message). The spread spectrum communication system determines the nominal PN offset of the given sector based on the measured PN offset and the location associated with the mobile station. If the given sector is a valid handoff destination, the spread spectrum communication system transmits to the mobile station a handoff instruction that identifies the given sector by the measured PN offset.

摘要： Methods and systems are provided for using DRCLocks for conducting call admission control. In an embodiment, an access node provides service to a plurality of access terminals on a carrier in a coverage area, where the plurality of access terminals does not include a first access terminal. The access node receives a request for new service on the carrier in the coverage area from the first access terminal over an air interface, and responsively determines whether an aggregate-DRCLock condition is met. If the aggregate-DRCLock condition is met, the access node denies the request for new service.

摘要： Systems and methods for adjusting the power control settings in a wireless communication network are provided. In one embodiment, a base station determines a target access terminal's use of service so far in a billing period, wherein the target access terminal is located in a sector of the wireless communication network.

摘要： A mobile station receives forward link signals and transmits reverse link signals for a communication session conducted via a wireless network. A controller maintains a reverse-active set that defines which sectors of the wireless network are used to receive the reverse link signals. When the mobile station transmits a request signal requesting the communication session, the controller may create the reverse-active set to include the sector that received the request signal with the highest signal strength. During the communication session, the signal strengths of the reverse link signals may be monitored in each of a plurality of sectors to obtain reverse-link signal strengths. The controller may maintain the reverse-active set based on the reverse-link signal strengths, adding sectors that report reverse-link signal strengths greater than an add threshold and dropping sectors that report reverse-link signal strengths less than a drop threshold.
