摘要： A method and system is disclosed for dynamically merging wireless service sectors in a wireless communication system. The method and system determines when certain conditions exist under which dynamically merging a plurality of wireless service sectors would advantageously yield an increased data rate for transmissions to access terminals (ATs) operating the plurality, while, at the same time, not resulting in a total traffic load that would be detrimental to system performance. The method and system also incorporate the manner and means of merging sectors so as to cause the plurality of wireless service sectors to operate as a single, dynamically-merged wireless service sector. Each access terminal operating in a dynamically-merged wireless service sector receives the full, combined power of all the sectors of the plurality during transmissions to that AT.

摘要： A mechanism for dynamically setting paging transmission power for a given mobile station based on the mobile station's paging slot frequency. For a mobile station that is set to operate at a higher paging slot frequency (e.g., lower slot cycle index), a wireless serving network transmits a page message to the mobile station at a higher power level, in order to increase the likelihood that the mobile station will successfully receive the page message. On the other hand, for a mobile station that is set to operate at a lower paging slot frequency (e.g., a higher slot cycle index), the network transmits a page message at a lower power level.

摘要： A method and system for controlling the rate at which access terminals hand off from an IS-2000 (e.g., 1xRTT) communication system to an IS-856 (e.g., EVDO) communication system. A base station determines metric indicative of the rate at which hybrid access terminals hand off to the IS-2000 from the IS-856 system, and then based at least in part on the metric, dynamically adjusts a dormancy period that at least one hybrid access terminal must wait before entering a dormant mode in which is looks for service under IS-856. As the rate-metric indicates a higher or lower rate, the system may responsively adjust the dormancy period down or up. The rate at which hybrid access terminals operating under IS-2000 may seek service under IS-856 may thus be tuned to the rate at which they hand of form IS-856 to IS-2000.

摘要： A method and system for controlling switching of an access terminals between wireless coverage areas such as cell sectors. A measure of actual level of service, such as throughput, provided to the access terminal across the combination of wireless coverage areas over time is determined. Further, for each wireless coverage area, a measure of predicted level of service, such as throughput, that would likely be provided to the access terminal if it operated in just that wireless coverage area is determined. If the actual level of service is greater than each predicted level of service, then the access terminal is allowed to continue switching between wireless coverage areas. On the other hand, if at least one of the predicted levels of service is greater than the actual level of service, then the access terminal is restricted to the wireless coverage area where the level of service is deemed greater.

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 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 defined that support, in a radio access network, measuring the latency between the radio access network and each respective access gateway of a plurality of access gateways. From these measurements, a list of access gateways, rank ordered from lowest to highest latency, is created. If the radio access network receives an incoming call indication designating that an associated incoming call is latency-sensitive, the radio access network will preferably assign the incoming call to an access gateway that is one with a measured respective round trip latency less than or equal to a median measured respective round trip latency. Additionally, the radio access network maintains a profile for at least some wireless communication devices that use its services. When the radio access network receives an incoming call indication for a wireless communication device, the radio access network preferably determines, from the wireless communication device's profile, if the wireless communication device has a history of heavy network usage. If the wireless communication device has a history of heavy network usage, the radio access network preferably assigns the incoming call to an access gateway that is one with a measured respective round trip latency greater than or equal to the median measured respective round trip latency.

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.
