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 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 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 method for selecting a wireless coverage sector to serve a mobile station, such as in response to a handoff request that designates a sector-identifier that represents two or more possible sectors. A serving radio access network (RAN) may identify potential sectors in the region and may then select the sector whose azimuth is closest to the geographic bearing of the mobile station from the sector's base station. Further, in the event of a tie between two or more sectors or in other circumstances, the RAN may also take into consideration how close the mobile station is to various base stations, such as selecting the sector to whose base station the mobile station is closest. In a system that uses neighbor lists to govern handoff, the invention can help to facilitate handoff in a scenario where a mobile station requests handoff to a sector not listed in the mobile station's neighbor list.

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： A controller monitors resource usage in each of a plurality of sectors and identifies any sector with resource usage that exceeds a threshold value as a high usage sector. The controller evaluates the mobile stations in its area and identifies any mobile station that is using a high usage sector and at least two other sectors for a communication session as a candidate mobile station. The controller applies a predictive algorithm to determine whether any candidate mobile station is able to continue its respective communication session without using its respective high usage sector. In this determination, the signal levels that a mobile station reported for the sectors in its active set, other than the high usage sector, may be used to calculate a combined signal level. If the combined signal level exceeds a predefined value, the mobile station is instructed to drop the high usage sector.

摘要： A power control command (PCC) transmission scheme is disclosed. In one embodiment, the PCC transmission scheme may involve an access network engaging in a respective communication session with each of a plurality of access terminals on a given wireless link and sending a respective series of PCCs directed to each of the plurality of access terminals on the given wireless link. Based on a power utilization of the given wireless link, the access network may then decide to adjust a transmission rate at which to send PCCs directed to a set of access terminals in the plurality of access terminals. In turn, the access network may send the respective series of PCCs directed to each of the set of access terminals at the adjusted transmission rate.

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： 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。
