摘要： A method and system is disclosed for shifting the phase of a PN long code for access attempts by an access terminal in a wireless communication network. An access terminal may seek to acquire access from a base station that is detected by the access terminal above a threshold power level, even if the access terminal is further away from the base station than a threshold distance beyond which access is not normally granted. According to one embodiment, the access terminal will, upon determining that it is beyond the threshold distance, embed in an access request message an apparent distance that is smaller than the threshold distance, by phase-shifting a timing signal and encoding the access request message with the phase-shifted timing signal. The access terminal will then transmit the access request message on an air interface communication link to the base station.

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 method and system for vertical handoff of a mobile station from a first-protocol RAN to a second-protocol RAN. The method and system provide a make-before-break vertical handoff, by having the first-protocol RAN (i) acquire, on behalf of the mobile station, a traffic channel assignment defining one or more traffic channel parameters for air interface communication in the second-protocol RAN, and (ii) pass to the mobile station, via the first air interface protocol, the one or more traffic channel parameters so that the mobile station can then readily switch over to communication under the second-protocol RAN. Optimally, the acquisition and passing of the one or more second-protocol traffic channel parameters may occur without the mobile station having requested the handoff, without the mobile station having asked for the traffic channel assignment, and without the mobile station having yet begun communication with the second-protocol RAN.

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 and system is disclosed for setting forward-link power for an access terminal operating in a coverage area of a wireless communication system, whereby power is redistributed from access terminals operating in the same coverage area and having forward-link power in excess of their needs for maintaining acceptable service quality, to an access terminal that is in need of additional forward-link power in order to attain a desired or required level of service quality. Following a determination that a given access terminal is requesting a forward-link transmission power level that exceeds a first threshold power level, a number of other access terminals are identified as each having requested a respective decrease in forward-link transmission power level by an amount at least as large as a respective threshold amount. Forward link power to the given access terminal is then increased by an incremental amount, and the forward-link transmission power level to each of the number of other access terminals is decreased by a respective decremental amount, wherein the sum of all the respective decremental amounts equals at least the incremental amount.

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.
摘要翻译：公开了用于隔行控制信道的方法和系统。当至少根据IS-856操作的无线通信系统中的RAN确定在向接入终端发送控制分组时存在延迟条件时，它调用带有控制信道数据的时隙的交织。通过这样做，以隔行方式发送控制分组，从而相比于控制分组的顺序发送减少传输延迟。延迟条件可以对应于超过阈值延迟的测量延迟，超过阈值的预测延迟（例如，基于队列占用），或者在特定时间间隔期间有资格接收控制消息的接入终端的数量超过不同的阈值数。 RAN可以在每个控制信道周期的基础上监视控制分组的传输延迟，并且仅在已经确定了延迟条件的控制信道周期中应用控制分组的隔行传输。

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.
