    • A communication system including a constellation of satellites and a multi-channel unit having a plurality of co-located transceivers operative for exchanging communication information with users, and for monitoring a plurality of spot beams transmitted from one or more of the satellites for ring alert data contained within broadcast channels, and for monitoring and prioritizing the strongest of "n" broadcast channels for ring alerts based upon signal strength, upon a continuous sampling of ring alert channels contained within one or more broadcast channels, upon broadcast signal strength in relation to idle transceiver availability and the communication system geometries, and upon the monitoring of broadcast channels contained within candidate handoff lists contained within one or more of the traffic channels of in-use transceivers, for the purpose of increasing the probability of receiving a ring alert.

    • A communication system (100) includes satellites (102,104) and a mobile exchange unit (MXU) (120) for exchanging communication information with users. A satellite (102) generates synchronous timing frames requiring users operating through an MXU (120) to anticipate timing and frequency requirements to participate in communications. An MXU (120) must advance transmissions to a satellite (102) to insure transmissions arrive at satellite (102) within the proper synchronous receive window. Such advanced transmissions by MXU (120) interfere with reception of a ring alert/page transmission (130) which contains the location of broadcast channels (86) designating an incoming call or page data transmissions. The MXU (120) alternatively extracts a broadcast channel location from a candidate hand-off list being transmitted by a satellite (102) to in-use transceivers (310). The MXU 120 then distributes the location of the broadcast channel to those transceivers (310) presently not in-use.
    • 通信系统(100)包括用于与用户交换通信信息的卫星(102,104)和移动交换单元(MXU)(120)。 卫星(102)产生需要用户通过MXU(120)进行操作的同步定时帧,以预测参与通信的定时和频率要求。 MXU(120)必须将传输提前到卫星(102),以确保传输到达适当的同步接收窗口内的卫星(102)。 MXU(120)的这种高级传输干扰包含指定呼入或寻呼数据传输的广​​播信道(86)的位置的环形警报/页面传输(130)的接收。 MXU(120)可替代地从由卫星(102)发送到使用中收发器(310)的候选切换列表中提取广播频道位置。 然后,MXU 120将广播频道的位置分配给当前未使用的收发器(310)。

    • A communication system includes base communication units (105, 155) facilitating a communication link with portable communication units (110) in motion relative to base communication units. The relative motion between base communication units (105, 155) and portable communication units (110) introduces Doppler frequencies into communication links (115, 165). When portable communication units (110) travel in a predictable direction (119), frequency offsets for Doppler compensation are generally predictable. However, when portable communication units (110) move erratically in relationship to a base communication unit (105, 155), frequency offsets for Doppler compensation are not easily calculated. Incorporation of velocity vector data into the frequency offset calculation for Doppler compensation provides reliable tracking and Doppler frequency compensation for erratic motion of portable communication units (110).
    • 通信系统包括便于与便携式通信单元(110)相对于基站通信单元运动的通信链路的基站通信单元(105,155)。 基站通信单元(105,155)和便携式通信单元(110)之间的相对运动将多普勒频率引入通信链路(115,165)。 当便携式通信单元(110)以可预测的方向(119)行进时,多普勒补偿的频率偏移通常是可预测的。 然而,当便携式通信单元(110)与基地通信单元(105,155)的关系不规律地移动时,不容易计算多普勒补偿的频率偏移。 将速度矢量数据结合到多普勒补偿的频率偏移计算中为便携式通信单元(110)的不稳定运动提供可靠的跟踪和多普勒频率补偿。
