摘要： A communication device converts a bit stream to multiple symbols and provides encryption at a physical layer by shifting a phase of each symbol of the multiple symbols to produce multiple encrypted symbols. Each encrypted symbol of the multiple encrypted symbols is modulated with an orthogonal subcarrier to produce at least one modulated subcarrier and the at least one modulated subcarrier is then transmitted via a wireless link. On a receive side, a receiving communication device receives the transmitted, encrypted symbols and provides decryption at a physical layer by shifting a phase of each encrypted symbol in correspondence with the phase used to encrypt the symbol at the transmit side.

摘要： Upon detecting (201) a communication need for a group of communication recipients that entails attempting to make at least one transmission to each of the communication recipients in the group (wherein at least one of the communication recipients has both a scheduled personal communication opportunity and a scheduled group communication opportunity), one automatically uses (202) whichever of the scheduled communication opportunities occurs first to make the at least one transmission to the communication recipient(s) for which this option applies. In one approach this response is further informed and influenced by one or more other factors, such as but not limited to system loading (203), group size and/or known whereabouts (204), and/or whether a recent transmission response was received (205).

摘要： A method includes transmitting a paging request message to a plurality of asynchronous base stations (102a-g) where a paging message is sent within its respective cell at any time within a given paging interval (202). The method continues by receiving notification that paged mobile station (106) has responded to a paging message. The page cancelling message indicates to the base stations do not need to send the paging message within their respective cells during the current paging interval and that the paging process is cancelled.

摘要翻译： 一种方法包括向多个异步基站（102a-g）发送寻呼请求消息，其中寻呼消息在给定的寻呼间隔（202）内的任何时间在其相应小区内被发送。 该方法通过接收寻呼移动站（106）已经响应寻呼消息的通知来继续。 页面取消消息指示给基站在当前寻呼间隔期间不需要在它们各自的小区内发送寻呼消息，并且取消寻呼过程。

摘要： Various embodiments are described for potentially reducing the impact of routing area updates on wireless system capacity. Logic flow diagram 10, in FIG. 1, depicts such functionality. In some embodiments, it is determined (12) whether a remote unit is within an edge portion of a routing area, while in other embodiments it is determined (12) whether the remote unit is within an end portion of a routing area update interval. It is also determined (14) whether one or more conditions are present for the remote unit to perform a resource-efficient routing update. A routing area update is then performed (16) when one or more of the conditions are present and when, depending on the embodiment, either the remote unit is determined to be within the edge portion of the routing area or the remote unit is determined to be within the end portion of the routing area update interval.

摘要： For a packet, a communication device determines (12) a length of a packet length field based on one or more of the following: a size of a transmit region allocated for a remote unit, a size of a transmit region allocated for a remote unit and not to be used for at least one other packet, and/or whether the packet length of the packet is indicated by a history of packet lengths of previously transmitted packets. The communication device may also or alternatively determine (22) a length of a connection identifier field based on a number of connection identifiers previously established. The communication device then transmits (13, 23) the packet, which includes the field(s) of determined length. By determining the lengths of these fields in this manner, the fields may be made shorter and their use may potentially reduce signaling overhead as compared to using the present-day fixed-length fields.

摘要： A method is provided for allocating initial ranging opportunities in a series of frames. According to the method, a number of initial ranging opportunities are allocated in frame N that occurs after a triggering event, and k frames after frame N the number of initial ranging opportunities is selectively reduced. The triggering event is one of system startup and broadcast of an Uplink Channel Descriptor message. Also provided is a base station that includes a controller for allocating a number of initial ranging opportunities in frame N that occurs after a triggering event. The controller selectively reduces the number of initial ranging opportunities k frames after frame N. The triggering event is one of system startup, broadcast of an Uplink Channel Descriptor message, broadcast of a page message, or broadcast of a signature for an overhead configuration message.

摘要： A communication system optimizes system performance by selectively managing which mobile stations (MSs) are to serve as test MSs. The test MSs report system operating parameters in order to detect sleeping cells, coverage holes, or other flaws in system coverage or in order to determine an impact of a change in an access network configuration. The communication system further provides for end-to-end messaging between the test MSs and network servers via an access network and a core network, thereby permitting network elements that are best able to perform system optimization to control the monitoring, measuring, and reporting by the MSs. To minimize system and user inconvenience, reporting by a test MS further may be based on one or more of whether the MS is in an area of low mobility, has an acceptable power source output level, and is operating in a cell with an acceptable load level.

摘要翻译： 通信系统通过选择性地管理哪些移动站（MS）用作测试MS来优化系统性能。 测试MSs报告系统操作参数，以便检测系统覆盖范围内的睡眠单元，覆盖漏洞或其他缺陷，或者确定接入网络配置更改的影响。 通信系统还通过接入网络和核心网络进一步提供测试MS和网络服务器之间的端到端消息，从而允许最能够执行系统优化的网络单元控制监控，测量和报告 MS。 为了最小化系统和用户不便，测试MS进一步报告可以基于MS是否处于低移动性区域中的一个或多个，具有可接受的电源输出电平，并且在具有可接受负载的小区中操作 水平。

摘要： Various embodiments are described herein to address the need for reducing call setup delays with respect to supplemental channels. Modifications to channel assignment messaging (104), such as an enhanced ECAM, and service connection messaging (108), such as an enhanced SCM, are described. These modifications enable the assignment of SCHs (110) earlier in the call setup sequence. In addition, embodiments for determining and anticipating when such modified messaging may effectively speed the transfer of data (including VoIP) between a BS (201) and an MS (210) are described.
