摘要： Methods and systems for assigning a wireless communication device to a carrier frequency are presented. In an exemplary embodiment, a radio access network (RAN) radiates to define one or more wireless coverage areas using at least two different carrier frequencies. A given wireless communication device (WCD) seeks to engage in a call, and accordingly transmits a probe message to the RAN. In response to receiving the probe message, and based at least on information associated with the probe message, the RAN determines an initial carrier frequency assignment for the given WCD. Preferably, this initial carrier frequency assignment is performed to balance load across at least some of the at least two different carrier frequencies. The RAN then transmits an indication of the carrier frequency assignment to the given WCD. The given WCD may then tune to the assigned carrier frequency and conduct communications using the assigned carrier frequency.

摘要： Methods and systems for carrier frequency management based on slot contention are provided. A radio access network (RAN) may radiate on one or more carrier frequencies to define wireless coverage areas. Each wireless coverage area may provide network access for one or more wireless communication devices (WCDs). In order to efficiently manage these carrier frequencies, the RAN may measure a slot contention metric for each carrier frequency. Based on the measured slot contention metrics, the RAN may perform a carrier frequency management function affecting at least one of the carrier frequencies. Carrier frequency management functions may include, but are not limited to, assigning a WCD to a carrier frequency, taking a carrier frequency out of service, and placing a new carrier frequency in service.

摘要： Disclosed herein is a mechanism to help improve message waiting notification. In accordance with the mechanism, when a RAN transmits an MWI to a mobile station after unsuccessful call setup paging of the mobile station, the RAN will transmit the MWI at a higher power level than the RAN used for transmitting the call setup paging. Using a higher transmission power specifically for the MWI should help the MWI reach the mobile station, particularly in a scenario where a reason for call setup paging failure was noise on the air interface. Consequently, the disclosed mechanism should help improve user experience by increasing the likelihood that mobile stations will receive and process MWIs soon after the associated voice mail messages are left.

摘要： Methods and systems are provided for using mobile-station revision ratio to improve reverse-link performance. An access node provides service to first and second subsets of access terminals, the first operating according to IS-856, Rel. 0, the second according to IS-856, Rev. A. The access node periodically transmits a reverse activity bit (RAB) to the access terminals, and also periodically computes a ratio of (a) either (1) the number of access terminals in the first subset or (2) the number of access terminals in the second subset to (b) a total number of access terminals in the first and second subsets, and transmits the ratio to at least the first subset. When the RAB is set, the access terminals in the first subset perform a ratio test by comparing the ratio with a threshold, and decrease their reverse-link data rates without reference to any reverse-link transitional probabilities when the computed ratio passes the ratio test.

摘要： Methods and systems are provided for improving reverse-link performance by using differentiated reverse activity bits (RABs) based on mobile-station revision. In an embodiment, an access node provides wireless service to first and second mutually exclusive sets of access terminals, the first operating according to IS-856, Release 0, the second according to IS-856, Revision A. The access node maintains first and second RAB thresholds, and periodically (a) measures reverse noise rise (RNR), (b) compares the RNR to the first and second thresholds, (c) transmits a first RAB to the first set of access terminals, and (d) transmits a second RAB to the second set of access terminals. The first RAB is set when the measured RNR exceeds the first threshold, and clear when it does not. The second RAB is set when the measured RNR exceeds the second RAB threshold, and clear when it does not.

摘要： A cellular wireless communication network transmits spread spectrum signals that are spread by a pseudonoise (PN) code with any of a plurality of PN offsets, such that different coverage areas use different PN offsets. In each coverage area, the network transmits a plurality of forward link channels, each defined by a respective Walsh code, without transmitting a pilot signal. A wireless communication device (WCD) begins operating in a given coverage area and determines the PN offset used in the given coverage area by receiving a forward link signal having a Walsh code of a sync channel, paging channel, or other channel that transmits a broadcast message. The WCD selects a target bit sequence that would be expected to be included in the broadcast message. The WCD finds an effective PN offset that enables the WCD to despread the forward link signal and recover the target bit sequence.

摘要： A method and corresponding system is disclosed for enhanced resource allocation in a wireless communication system. According to the method, when an idle wireless device seeks to initiate a call in a given coverage area, the device will provide with its initiation request to the serving radio network a motion specification indicating an extent of movement of the device, based on the device's tracking of its own movement. The network will then use that motion specification provided with the initiation request as a basis to determine whether to select a resource to allocate for the call in the given coverage area based on resource implementation in at least one neighboring coverage area or whether to instead select the resource to allocate without regard to resource allocation in the at least one neighboring coverage area.

摘要： Methods and devices for transmission of communications during a silence interval are described. A base station (BS) provides timing data to an access terminal (AT) and AT uses timing data to synchronize with BS to carry our silence and non-silence intervals for an RF air interface. AT attempts to initiate communications by transmitting an access probe (AP) to BS during a non-silence interval. Other ATs may transmit communications to BS during non-silence interval. If BS acknowledges AP during non-silence interval, AT does not transmit during a subsequent silence interval. If AP was for an emergency communication and BS does not acknowledge AP sent during non-silence interval, AT transmits another AP during the subsequent silence interval to initiate emergency communication. If AP was not for emergency communication, AT does not transmit AP during the subsequent silence interval. The other ATs do not transmit communications to BS during the subsequent silence interval.

摘要： Methods and systems for reducing the latency of instant communication session establishment are presented. According to various preferred embodiments, a RAN, may receive a setup request message via a packet-switched network. The RAN may determine, from a quality of service (QOS) indication contained in the setup request message, that the setup request message is requesting establishment of a instant communication session. The RAN may further determine an intended destination wireless communication device (WCD) for the setup request message. Based on the QOS indication and/or a profile indicating the destination WCD's capabilities, the RAN may pre-allocate resources for the instant communication session in parallel to paging the destination WCD. In this way, the latencies associated with these procedures are overlapped, thus reducing the overall latency of instant communication session establishment.

摘要： Methods and systems are provided for adjusting the volume on a mobile station earpiece based on reverse frame data rate. In an embodiment of the invention, a mobile station transmits a plurality of reverse frames over a specified period of time. For each frame in the plurality of reverse frames, the mobile station measures a reverse frame data rate. The mobile station then uses the measured reverse frame data rates to calculate an average reverse frame data rate for the reverse frames transmitted over the specified period of time. Next, the mobile station adjusts the volume level of an earpiece based at least in part on the average reverse frame data rate.
