Group identification codes, names of parties to be sent, and telephone numbers of the pagers of the parties to be sent are stored in groups in memory,of a selective pager. At the time of transmission of a message, telephone numbers of a specified group and a message to be sent for the group are selected from the memory. The telephone numbers and the message are alternately sent to a DTMF signal generation section,, which converts the telephone numbers and the message to DTMF signals. The DTMF signals are then converted into acoustic signals by means of a speaker,and are continually transmitted by way of a transmitter of a telephone set. As a result, a group call can be implemented without involving laborious operations, such as transmission of the telephone numbers and the message one by one.

Selective pager and paging system

Messages received through information delivery are classified by a message identification section. The thus-classified messages are stored into a specified folder by means of a folder management section and are managed for each level in a hierarchy. When a new message is stored into the specified folder, a folder setting section causes a paging control section to page the user by means of a speaker, a vibrator, or an LED or causes a display control section to display the arrival of a message on an LCD. So long as the folder is set to a shortcut folder, a desired information item can be read in a prioritized manner.
