1. In a paging system capable of communication between a caller and more than 2n pagers, said system including a base station for sequentially transmitting first and second radio signals to said pagers, said first radio signal including a first address word which includes only n bits for identifying said more than 2n pagers, and wherein a leading portion of said first address word includes first identification indicia for indicating that said first radio signal is an address word which includes called-pager number data, said second radio signal including a message word, and wherein a leading portion of said second radio signal includes second identification indicia for indicating that said second radio signal is a message word signal which includes message data, wherein each of said pagers comprise:

  • means for receiving said first and second radio signals transmitted by said base station;

    a called-pager number data storage means for storing called-pager number data assigned to said pager;

    selection data storage means for storing selection data assigned to said pager;

    first detecting means for detecting a coincidence between said called-pager number data included in said received first address word and said called-pager number data stored in said called-pager number data storage means;

    first message data storage means, which upon detection of a coincidence by said first detecting means, stores said message data included in said message word;

    second detecting means for detecting whether said stored data in said first message data storage means includes predetermined function data;

    third detecting means coupled to said second detecting means which upon detection of said predetermined function data by said second detecting means then determines whether said message data stored in said first message data storage means includes data identical to said selection data stored in said selection data storage means; and

    display means for displaying said message data stored in said message data storing means;

    when said second detecting means does not detect said predetermined function data; and

    when said third detecting means detects that data identical to said selection data is present in said first message stored in said message data storage means.
