摘要： A method and apparatus for selecting channel elements in a wireless communication system based on their performance history. Data is collected indicating the performance of various channel elements over time, preferably eliminating from consideration any performance degradation due to air interface (e.g., radio frequency) issues. The data is then used to sort the channel elements in a priority order, from best-performing to worst-performing. When a channel element is to be selected for use in connection with an air interface channel (e.g., traffic channel or control channel), the channel element is then selected in accordance with the priority order, such as by selecting the channel element that has performed best over time. The priority-based selection of channel elements can thus leave poor-performing channel elements for use as a last resort, which can be advantageous in times of heavy network loading for instance.

摘要： A mobile station transmits a message by transmitting an access probe that includes the message preceded by a preamble. The mobile station selects the length of the preamble from among a first preamble length and a second preamble length. The second preamble length is greater than the first preamble length. The mobile station makes the selection based, at least in part, on the distance between the mobile station and the mobile station's primary base transceiver station (BTS). If the distance is greater than a threshold distance, the mobile station selects the second preamble length. If the distance is less than the threshold distance, the mobile station selects the first preamble length, provided that an idle handoff to a neighboring BTS that is more than the threshold distance away is unlikely.

摘要： A method and system is disclosed for enhanced idle-state sector selection during hybrid-mode operation of an access terminal. A hybrid access terminal engaged in an IS-856 data communication session in a hybrid IS-2000/IS-856 wireless communication system will, responsive to a handoff of the IS-856 session, select a sector for its next, upcoming IS-2000 idle-state scan prior to the start of the scan. The selection will be made during an interval between IS-2000 idle-state scans, thereby reducing or eliminating the possible need for idle-state handoffs during idle-state scans, and resulting in shorter idle-state scans and better IS-856 performance.

摘要： A method of selecting a type of resource-allocation to use for a call in a cellular wireless system, such as selecting a type of radio configuration to use for the call. According to the method, resource-availability in one more adjacent coverage areas may be used as a basis to select the type of resource-allocation to use in a current coverage area. For instance, given the choice between a radio configuration that consumes less base station power and a radio configuration that consumes more base station power, the radio configuration consuming more base station power may be selected if base station sufficient power is available in one or more adjacent coverage area(s), and the other radio configuration may be selected if insufficient base station power is available in the one or more adjacent coverage area(s). Distance between the mobile station and a current base station may be considered as well.

摘要： A mobile station uses a search window to search for a target pilot signal transmitted by a target transmitter in a spread spectrum communication system. The search window may be centered on the expected phase of the target pilot signal at the mobile station. To calculate the expected phase, the mobile station estimates a transmission delay associated with the target pilot signal, based on at least the target transmitter's location and the mobile station's location. The transmission delay may account for the time it takes for the target pilot signal to propagate from the target transmitter to the mobile station. The expected phase of the target pilot signal may then be calculated based on at least a nominal phase of the target pilot signal (e.g., the phase when transmitted by the target transmitter) and the estimated transmission delay.

摘要： A method and system is disclosed for interlaced control channel. When a RAN in a wireless communication system operating at least according to IS-856 determines that a delay condition exists in the transmission of control packets to access terminals, it invokes interlacing of time slots bearing control-channel data. By so doing, control packets are transmitted in interlaced fashion, thereby reducing delay in transmission compared with sequential transmission of control packets. A delay condition could correspond to a measured delay exceeding a threshold delay, a predicted delay (e.g., based on queue occupancy) exceeding a threshold number, or the number of access terminals eligible to receive control messages during a particular time interval exceeding a different threshold number. The RAN may monitor transmission delay of control packets on a per-control-channel-cycle basis, and apply interlaced transmission of control packet only during those control-channel cycles for which a delay condition has been determined to exist.

摘要： A method and system is disclosed for intelligent power control in a wireless communication system. In accordance with an example embodiment, a first device will operate in a dynamic-power state in which it responds to each power-increment command and power-decrement command received from a second device by incrementing or decrementing transmission power on an air interface. While operating in the dynamic-power state, the first device will recognize when a first threshold number of alternating power-increment and power-decrement commands have been received, and responsively will transition to operating in a steady-power state in which it no longer increments or decrements transmission power in response to power-control commands from the second device. While operating in the steady-power state, the first device will recognize when receives a particular sequence of power-control commands from the first device, and based at least on the recognition will transition to operating in the dynamic power state.

摘要： Methods and an apparatus are provided for providing handoff information to a candidate mobile node initially served on a first carrier. The candidate mobile node may inform a wireless-communication network that hard-handoff criteria are met for the first carrier. The network may identify a plurality of neighboring mobile nodes served on a second carrier and within a threshold distance of the candidate. The network may receive a measurement of forward-link signal quality of the second carrier from each neighboring mobile node. Using the received forward-link-signal-quality measurements, the network may estimate the forward-link signal quality of the second carrier at the location of the candidate mobile node. If that estimated forward-link signal quality exceeds a signal-quality threshold, the network may provide hard-handoff information about the second carrier to the candidate mobile node.

摘要： Disclosed herein is a method for improved paging in a wireless communication system. In a scenario where base stations broadcast congestion indicators to prevent mobile stations from registering in coverage areas that are experiencing threshold congestion, the method provides for a new form of zone based paging that accounts for the possibility that a mobile station has entered into a new zone but has not yet registered due to a threshold congestion state. According to the method, a paging attempt will be directed to the mobile station's zone of last registration and to only those coverage areas in at least one adjacent paging zone that are deemed to be experiencing threshold congestion.

摘要： Air interface protocols under the numerous wireless communication standards allow use of a quick-paging channel (QPCH) to expedite paging and call setup. When a hybrid mobile device is engaged in wireless communications under a first air interface protocol, it may periodically switch over to a second air interface protocol to check for pages on the slower standard paging channel (PCH). To increase throughput under the first air interface protocol, it would be useful to employ the QPCH under the second air interface protocol, to reduce time spent by hybrid device checking for pages under the second air interface protocol. However, the QPCH uses resources under the second air interface protocol, so it would be best to not have the QPCH activated at all times. According to the invention, the system would activate the QPCH under the second air interface protocol in response to there being more than an upper threshold number of hybrid devices active under the first air interface protocol. In turn, the system may deactivate the QPCH under the second air interface protocol in response to there being some lower threshold number of hybrid devices active under the first air interface protocol.
摘要翻译：许多无线通信标准下的空中接口协议允许使用快速寻呼信道（QPCH）来加速寻呼和呼叫建立。当混合移动设备在第一空中接口协议下进行无线通信时，它可以周期地切换到第二空中接口协议以检查较慢的标准寻呼信道（PCH）上的页面。为了增加第一空中接口协议下的吞吐量，在第二空中接口协议下采用QPCH将有助于减少混合设备检查第二空中接口协议下的页面所花费的时间。然而，QPCH使用第二空中接口协议下的资源，因此最好不要始终激活QPCH。根据本发明，系统将在第二空中接口协议下激活QPCH，以响应在第一空中接口协议下存在多于高阈值数量的混合设备。反过来，系统可以在第二空中接口协议下响应于在第一空中接口协议下有一些较低阈值数量的混合设备有效而在第二空中接口协议下去激活QPCH。
