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 scheduler and a method for scheduling transmissions to a plurality of users in a communication network assigns a higher target minimum throughput for receiving a next transmission to a user based on a quality of service (QoS) class of the user. A token count that tracks the user's achieved performance relative to a target minimum throughput Is determined for each user in given timeslot, and a weight is determined for each user based on one or more of the token count and a current rate requested by the user. A user having the highest weight as determined by a weight function is scheduled to be served the next transmission. User priority for scheduling may be downgraded if an average data rate requested by the user is less than the target minimum throughput.

摘要： A method for scheduling transmissions to a plurality of users in a communication network determines a satisfaction metric and a dissatisfaction metric for each user in a given timeslot that is to be used for a next scheduled transmission to one of the users. Each user is assigned a weight based on a value of at least one of the user's satisfaction metric, the user's dissatisfaction metric and a rate requested by the user. The use having the highest weight is selected to be served the next scheduled transmission in the given timeslot.

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： In one embodiment of the method of adaptively selecting an airlink coding scheme in a telecommunications network, a coding scheme operating region is determined based on a currently used coding scheme and measurements representative of a block error rate. A block error coding scheme is determined based on the determined coding scheme operating region. In another embodiment of the method of adaptively selecting an airlink coding scheme in a telecommunications network, a first coding scheme is determined based on measurements representative of one or more conditional channel quality metrics, and a second coding scheme is determined based on measurements representative of a block error rate. One of the first and second coding schemes is selected as the coding scheme.

摘要： In a system having a base station transmitter for transmitting data blocks to one or more mobile stations over a radio link, there is a method for determining an uplink transmit power level at which to transmit a current data block over a radio link from the mobile to the base transmitter station. The method evaluates airlink quality measurements in the radio link over a measurement interval, wherein each time a message is sent to the mobile station, it is evaluated whether a specified number of uplink blocks have been transmitted by the mobile station since the start of the measurement interval. Based on the evaluated airlink quality measurement, the method determines the uplink transmit power level that the mobile should be using for the current block, and adjusts the transmit power level, if necessary, for the current block.
