    • A two-way paging system utilizes four local frequencies for transmissions between pager units (22) and a central control station (20). A first local frequency (f1) carries a local clock; a second local frequency (f2) carries communications packets from the central control station to paging units; a third local frequency (f3) carries communication packets from the pager units to the central control station; and a fourth local frequency (f4) carries a status or request signal from the paging units (22) to the central control station (20). Transmissions on the fourth local frequency (f4) are in accordance with a time divided slot allocation among pager units accessing the central control station (20). For a two-way paging system having a plurality of central control stations (420x) servicing a corresponding plurality of cells, a total of eight frequencies are utilized within any one cell. Four of the utilized frequencies are the local frequencies (f1-f4) Äwhich may differ from cell to cellÜ, and four of the utilized frequencies are lower power common frequencies or switching frequencies (C1-C4) which are used to switch or hand-off a pager unit (422) traveling from one cell to another.
    • 双向寻呼系统利用四个本地频率用于寻呼机单元(22)和中央控制站(20)之间的传输。 第一本地频率(f1)携带本地时钟; 第二本地频率(f2)从中央控制站向寻呼单元传送通信分组; 第三本地频率(f3)从寻呼机单元向中央控制站传送通信分组; 和第四本地频率(f4)从寻呼单元(22)向中央控制站(20)传送状态或请求信号。 第四本地频率(f4)上的传输与访问中央控制台(20)的寻呼机单元中的时分时隙分配一致。 对于具有服务相应多个小区的多个中央控制站(420x)的双向寻呼系统,在任何一个小区内总共使用八个频率。 所用频率中的四个是本地频率(f1-f4)[其可能在小区间不同],并且所用频率中的四个是低功率公共频率或用于切换或切换的切换频率(C1-C4) - 切断从一个小区到另一个小区的寻呼机(422)。

    • The present invention relates to a paging network system containing at least two independent paging networks with paging terminals, each of the paging networks containing means for storing paging terminal location information and means for treating paging information, whereby at least one linking arrangement is provided between the at least two paging networks which controls data flow between the paging networks. The linking arrangement contains means for treating location information assigned to paging terminals of at least one of the paging networks. Further a method and an arrangement for controlling data flow between independent paging networks with user terminals are provided, whereby location information of paging terminals of the paging networks is stored in the paging networks and the data flow between the data networks is controlled by a linking arrangement independent form the paging networks.

    • A time-division multiplexed paging system for transmitting multiple paging messages on the same frequency. A geographic area is divided into a plurality of cells (30-50) having base stations that transmit radio frequency signals in the cells. Each base station is assigned a time slot (A, B or C) at which paging messages may be transmitted. The assignment is made such that no base stations having overlapping radio frequency coverage areas transmit during the same time. A locate signal is simultaneously broadcast throughout a geographic area in order to locate a paging unit (P1). Upon receipt of the locate signal, the paging unit (P1) transmits an acknowledge signal back to the paging system. The cell (30) in which the paging unit (P1) is located is determined based upon the signal strength of the received acknowledged signal. A paging message is transmitted from the base station in the cell (30) in which the paging unit (P1) is located during the time slot (A) that is assigned to the base station.
    • 时分多路复用寻呼系统,用于在同一频率上发送多个寻呼消息。 一个地理区域被分成多个小区(30-50),这些小区具有在这些小区中发送无线电频率信号的基站。 每个基站被分配一个可以发送寻呼消息的时隙(A,B或C)。 指派是这样进行的,使得在同一时间内不存在具有重叠射频覆盖区域的基站。 定位信号在整个地理区域同时广播,以便定位寻呼单元(P1)。 一旦收到定位信号,寻呼单元(P1)就发送一个确认信号回寻呼系统。 寻呼单元(P1)所在的小区(30)是根据接收到的确认信号的信号强度确定的。 寻呼消息在分配给基站的时隙(A)期间从寻呼单元(P1)所在的小区(30)中的基站发送。
