Abstract

PURPOSE:To transmit conditions to the other party of speaking by providing a connector with a squelch circuit, a message sending circuit, or the like and automatically sending a message even at the time when a speaker goes out of a range during speaking or speaking is broken by power-off. CONSTITUTION:When a connector detects the degradation in S/N or the like by a squelch circuit 12 during speaking to a radio telephone set 2, the message is sent from a message sending circuit 8 to a telephone line 3 for T1-number of seconds. That is, conditions such that speaking through the telephone set 2 is impossible or speaking is not restored at the time of elapse of T1-number of seconds after sending of the message and the countermeasure method that necessary messages can be recorded following the message, are informed to the other party of speaking. When it is not discriminated that speaking is possible within T1-number of seconds after sending of the message, a clearing signal is sent to the telephone set 2, and a message is recorded for a maximum of T2-number of seconds as desired by the other party of speaking and a line relay 4 is opened, and a user of a radio telephone equipment reproduces and confirms the recorded messages. Thus, the other party of speaking detects conditions though speaking is broken halfway.

(Problems to be Solved by the Invention) In the above-described conventional connection device for a wireless telephone device, the user goes out of the service area during a call or the wireless telephone is turned off.
When the S / N is deteriorated, it sends the T 3 seconds music on hold, as long as the S / N within the holding tone sending after T 3 seconds does not return, would talk about the end to open the line relay. In such a control method, when a call is disconnected during an out-of-service area or when the power of the wireless telephone is turned off during a telephone call, the user of the wireless telephone device can determine the situation. I can't decide whether to do it. In addition, since the call is ended regardless of the intention of the user of the wireless telephone device, there is a problem that the user is confused when an important business is scheduled.
