摘要： In a method of tracking a user in a communication network supporting a broadcast-multicast service, the network classifies groups of users into tracking areas. Movement of a user may be tracked as the user crosses a boundary between two tracking areas in the network. The method may enable a balance to be achieved between use of uplink overhead and the level or granularity of tracking desired, so as to conserve radio resources.

摘要： A push-to-talk (“PTT”) group call system, for use as, e.g., a public safety wireless network, includes a CDMA-based 1x-EVDO radio access network operably connected to a PTT server over an IP network. The radio access network includes base stations for radio communications with a number of distributed mobile stations. In carrying out wireless communications, the group call system combines IP-based voice and other real-time multimedia services with the 1x-EVDO radio access network's Broadcast Multicast Service. This allows a number of users to receive the same copy of an IP-based media stream for point-to-multipoint, group transmissions. To reduce call setup times, the group call system uses “standing” call groups, which are ongoing group communication channels pre-established between the PTT server and authorized group users. Thus, mobile stations link to one or more standing call groups of interest upon power-up, prior to users speaking.
摘要翻译：用作例如公共安全无线网络的即按即说（“PTT”）组呼叫系统包括通过IP网络可操作地连接到PTT服务器的基于CDMA的1x-EVDO无线接入网络。无线电接入网络包括用于与多个分布式移动台进行无线电通信的基站。在进行无线通信时，群呼系统将IP语音和其他实时多媒体业务与1x-EVDO无线接入网广播组播业务相结合。这允许多个用户接收用于点对多点，组传输的基于IP的媒体流的相同副本。为了减少呼叫建立时间，组呼用系统使用“站立”呼叫组，这是PTT服务器和授权组用户之间预先建立的正在进行的组通信信道。因此，在用户说话之前，移动站在上电时链接到一个或多个常用呼叫组。

摘要： Various methods and devices are provided to address the need for improved cooperation-based signal processing. In a first method, network equipment determines (801) a set of dominant interferers for a wireless transmission and requests (802) user-plane data corresponding to each dominant interferer in the set of dominant interferers. The network equipment then processes (803) a received signal corresponding to the wireless transmission to extract the information transmitted. This processing uses at least some user-plane data corresponding to at least one dominant interferer in the set of dominant interferers.

摘要： Methods and systems for generating a variable spacing pulse position modulated (VSPPM) signal for transmission across an ultra-wideband communications channel. The variable pulse position modulated spread spectrum signal is created by encoding every M input data bits from an input data stream into a symbol consisting of Nc chips. Each chip is divided into 2M sub-chips and each sub-chip is further divided into Np time slots. A pulse is transmitted for each chip in the symbol. During each chip period, the pulse is placed in the sub-chip corresponding to the binary M-tuple (or symbol) value. A time hopping code sequence consisting of Nc elements with a one-to-one chip association is then applied to each symbol so that the position of each pulse is shifted to the appropriate time slot that corresponds to the time hopping code value.
