[0095]

As described above, the first to fifth embodiments of the present application are described.
According to the invention, when a plurality of selective polling is to be received from a terminal capable of a plurality of selective polling communications, and the polling transmitter does not have the function, a message to that effect is displayed to the user, This makes it possible to designate one selective polling and perform polling reception by a simple operation without re-entering polling, which is extremely convenient.

Further, according to the third invention of the present application, when a user selects a plurality of selective polling after a call is made, if the polling transmitter does not have a plurality of selective polling transmission functions, the second one is selected. The subsequent selective polling cannot be set, and the operator can be notified to that effect. Therefore, an easy-to-use device without user misunderstanding can be provided.

Further, according to the fourth invention of the present application, it is possible to update the registration information as to whether or not a plurality of selective polling communications are possible in accordance with a call destination, and to make an accurate judgment. Becomes possible.

According to the sixth to ninth aspects of the present invention, when one selective polling is selected, a plurality of selective polling receptions are requested to the polling transmitter when real-time polling is received. This enables selective polling reception to be added during the middle of communication.On the other hand, at the time of timer polling reception, since there is no manual operation, it is determined that the addition of selective polling reception during the middle of communication is small, and multiple selective polling reception is performed. Since no request is made, the protocol becomes an existing protocol, and defects in the protocol can be extremely reduced.
