PROBLEM TO BE SOLVED: To provide a communication equipment, with which multiple subscribers can speak each other through public speech and transceiver speech. SOLUTION: When a transceiver call is originated to a PHS terminal PS1 from another PHS (R) terminal PS3 (b), while the owner of the terminal PS1 makes public speech via a communication network 1 (a), the terminal PS1 shifts to the transceiver speech by reserving the public speech (c). When the terminal PS1 cancels the reservation of the public speech thereafter, three- subscriber speech is held among the PHS terminals PS1, PS2, and PS3 by a public speech and transceiver speech (d). In the three-subscriber speech, the terminal PS1 synthesizes the aural data of the terminals PS2 and PS1 and transmits the synthesized data to the terminal PS3, and at the same time, synthesizes the aural data of the terminals PS3 and PS1 and transmits the synthesized data to the terminal PS2 via a base station 2a. |
