PURPOSE: To attain two-way talking between pagers integrated with radio telephone set within a service area of which radius is several tens of meters by discriminating and confirming plural talking request calls based on an added identification number. CONSTITUTION: When a user of a pager 1 depresses a speech button and a reception section 16 receives a reception signal with a master ID from a stationary equipment 2, a call signal with a slave ID specific to the pager 1 added thereto is sent. A speech control section 21 of the stationary equipment 2 confirms the master ID of a radio speech channel 24 and sends a call acknowledge signal, the pager 1 uses a control signal 19 to compare and confirm the ID with a slave ID in a fixed memory 11 to finish assignment of a radio speech channel. When the user depresses a call button, the identification number is collected, a speech request sequence number is added to the slave ID to form a pager identification number and it is sent to a speech connection destination pager 7 and stored in a variable memory 14 in the pager 1. Then a called signal from the destination pager 7 is compared with the pager identification number in the memory 14 to discriminate the speech request call. |
