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： Rather than transmitting a large full Broadcast-Multicast Services (BCMC) Parameters Message (BSPM) containing a full set of BSPM parameters pertaining to all active BCMC flows within a sector on an infrequent basis, smaller-sized differential or partial BSPMs are instead transmitted. Differential BSPMs contain updated information for existing flows or information for new flows, and because of their smaller size, can be transmitted more frequently than full BSPMs. A mobile terminal receiving a differential BSPM updates the flows with the information contained within the differential BSPM or adds the information contained within the differential BSPM for a new flow. Partial BSPMs divide the flow information contained in a large full BSPM over a plurality of smaller-sized partial BSPMs, which are separately and sequentially transmitted at different times. A mobile terminal receiving these partial BSPMs then reconstructs the full BSPM from a collection of received partial BSPMs.
摘要翻译：而不是发送一个大量的完整的广播 - 组播服务（BCMC）参数消息（BSPM），其中包含与不频繁的扇区内的所有活动BCMC流有关的全套BSPM参数，更小尺寸的差分或部分BSPM被传输。差分BSPM包含用于新流的现有流或信息的更新信息，并且由于其较小的尺寸可以比全BSPM更频繁地传输。接收差分BSPM的移动终端用包含在差分BSPM内的信息更新流，或者添加包含在差分BSPM中的信息用于新流。部分BSPM将多个较小尺寸的部分BSPM中的大型完整BSPM中包含的流信息进行划分，这些BSPM在不同时间是单独依次发送的。接收这些部分BSPM的移动终端然后从接收的部分BSPM的集合中重构完整BSPM。

摘要： A method of triggering registration of a mobile station in a network supporting broadcast multicast services employs registration triggers based on flow conditions and frequency conditions. For example, a registration message may be generated based on a change in frequency, from a first frequency to a second frequency, that is monitored by the mobile station. If the second frequency is not known to the network based on flow identifier information previously registered by the mobile station with the network, a registration to the network is triggered. By sending a registration, the network may page a mobile station on a single, given frequency, since the registration message indicates the mobile station's presence on that given frequency.

摘要： A method for access assurance in a wireless communication system, e.g., a mobile phone network, involves allocating communication resources for transactions between the network and various wireless access terminals (each having a unique identifier) based on priority classes assigned to the access terminals. The access terminals are divided into different priority classes based on public policy and similar considerations. Each access terminal's priority class is associated with its identifier in a database. Upon communicating with an access terminal, the network determines the access terminal's priority class based upon its identifier as received by the network, e.g., the identifier is correlated to the priority class in the database. Transaction priority levels are then calculated based on each access terminal's priority class. Air interface resources are allocated according to the computed transaction priority levels and one or more pre-determined allocation precedence rules governing priority.

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”）组呼叫系统包括基于CDMA的1x-EVDO无线电接入网络，其通过IP网络可操作地连接到PTT服务器。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 a system having a base station transmitter for transmitting data blocks to one or more mobile stations over a radio link, a method for determining a transmit power level at which to transmit a current block. A quality measurement is received from a mobile station indicating an average radio link quality over a previous group of blocks, wherein not all of the blocks of the previous group of blocks were necessarily transmitted at the same transmit power level. A transmit power attenuation level is determined for the current block based on the quality measurement. The transmit power attenuation level is subtracted from the initial transmit power level to determine the transmit power level for the current block.
