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： Disclosed are methods for determining which page attempt to shed. In accordance with these methods, when a page attempt from a first sequence directed to a first access terminal (AT) contends with a page attempt from a second sequence directed to a second AT for transmission over the air interface of a RAN, the RAN determines which sequence has been shed to a greater extent. The RAN then transmits the page attempt from the sequence that has been shed to a greater extent and sheds the page attempt from the sequence that has been shed to a lesser extent. The methods advantageously help to avoid one sequence of page attempts being disproportionately shed.
摘要翻译：公开了确定哪个页面尝试脱落的方法。根据这些方法，当从指向第一接入终端（AT）的第一序列的寻呼尝试与来自定向到第二AT的第二序列的寻呼尝试相抵触，以在RAN的空中接口上传输时，RAN确定哪个序列已经被更多的减少了。然后，RAN从已经流出的序列发送页面尝试到更大的程度，并且从已经流式化的序列中减少寻呼尝试。这些方法有利地有助于避免一连串的页面尝试被不成比例地流失。

摘要： A method and system is disclosed for dynamic adaptation of reverse-link power control based on the distribution of ATs implementing different protocol versions. An access terminal in a wireless communication system that includes a base station may operate in a first state in which, at least, the access terminal uses a first protocol for determining and adjusting transmission power on a reverse link of an air interface with the base station. While operating in the first state, responsive to receiving a protocol version message from the base station on a forward link of the air interface, the access terminal will transition to operating in a second state in which, at least, the access terminal uses a second protocol for determining and adjusting transmission power on the reverse link of the air interface with the base station. The first protocol is different from the second protocol.

摘要： A radio access network (RAN) receives a request to route a call from a caller to a mobile station, assigns a wireless traffic channel to the mobile station for the call, and detects a no-answer condition for the call (because a user of the mobile station does not answer the call within a predetermined time period or has chosen to ignore the call). In response to the no-answer condition, the RAN redirects the call to a voice mail system and keeps the wireless traffic channel assigned to the mobile station while the caller interacts with the voice mail system. The RAN determines that the caller has left a voice mail message on the voice mail system and transmits an indication of the voice mail message to the mobile station over the wireless traffic channel.
摘要翻译：无线接入网（RAN）接收从呼叫者呼叫到移动台的呼叫请求，为移动台分配无线业务信道给移动台，并且检测呼叫的无应答状况（因为用户的移动台在预定时间段内没有应答呼叫或者已经选择忽略该呼叫）。响应于无应答条件，RAN将呼叫重定向到语音邮件系统，并且在呼叫者与语音邮件系统交互的同时将无线业务信道分配给移动台。 RAN确定呼叫者已经在语音邮件系统上留下语音邮件消息，并通过无线业务信道向移动台发送语音邮件消息的指示。

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.
摘要翻译：移动台通过发送包括前导码前面的消息的接入探测器来发送消息。移动站从第一前导码长度和第二前导码长度中选择前导码的长度。第二前导码长度大于第一前导码长度。移动台至少部分地基于移动台和移动台的主基站（BTS）之间的距离进行选择。如果距离大于阈值距离，则移动站选择第二前同步码长度。如果距离小于阈值距离，则移动台选择第一前导码长度，前提是对邻近BTS的空闲切换超过阈值距离不太可能。

摘要： A method and system is disclosed for selectively scheduling control channel messages ahead of traffic channel data. 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 a particular control packet to access terminals, the RAN will determine if there is a particular traffic packet in active transmission that is classified according to best effort service (or similarly-characterized service class), and further if at least a threshold number of a nominal number of time-slot segments of the particular traffic packet remain untransmitted. If such a traffic packet is identified, the RAN will cancel transmission of the particular traffic packet and replace it with immediate transmission of the particular control packet.
摘要翻译：公开了用于在业务信道数据之前有选择地调度控制信道消息的方法和系统。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特定控制分组时存在延迟条件时，RAN将确定是否存在主动传输中的特定业务分组根据尽力服务（或类似特征的业务类别）进行分类，以及进一步地，如果特定业务分组的至少一个阈值数量的时隙段的标称数目保持未被发送。如果识别出这样的业务分组，则RAN将取消特定业务分组的传输，并将其替换为特定控制分组的即时传输。

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 apparatus for handing off packet-transmission between sectors of a wireless communication system is disclosed herein. During transmission of a packet from an access network to an access terminal, the access terminal determines that the packet should theoretically be transmitted to the access terminal in fewer timeslots in another sector than the number of allowed timeslots remaining for the packet transmission in a current sector. In response, the access terminal abandons packet transmission in the current sector and hands off to the other sector, in an effort to increase throughput and save air interface resources.
