Description

  The present invention relates to a cordless telephone apparatus that performs high-speed transfer and displays a simple real-time state.

Conventionally, a cordless telephone is transferred as follows.
(1) The slave unit of the analog cordless telephone is wirelessly connected to the master unit only at the time of outgoing / incoming call.
(2) When a handset is called (incoming call or the like), after performing wireless connection control on the control channel, it is called after shifting to a communication channel for communication.
(3) The usage status of each line can be grasped when the slave unit attempts to establish a wireless connection.

A flowchart of a conventional cordless telephone receiving a transfer will be described with reference to FIG. In FIG. 3, when an external line is received at the base unit, each base unit performs wireless connection control with respect to the corresponding cordless telephone, and sends a ringing tone to the cordless telephone through its own call channel. Each cordless telephone rings a ringing tone sent via a call channel assigned to itself. The cordless telephone that responds first maintains the call channel assigned to itself and enters a call state. However, the cordless telephone that does not respond first stops ringing and opens the call channel and enters a standby state.

Now, when the cordless telephone responder first responds to perform the transfer, the other cordless telephone is called. When the master unit detects this call signal, it performs wireless connection control on the cordless telephone that has received the call, and performs the operation of selecting and connecting the call channel again. When a cordless telephone that has received a transfer call on the connected call channel responds to the call, the transfer ringing stops and a call state is established.

As shown in FIG. 3, since the telephone that receives the transfer first arrives but does not respond first, the wireless connection section ends, and the wireless connection section is generated to perform the wireless connection again to receive the transfer. For this reason, when receiving a transfer, the wireless connection control must be performed from the beginning, and the transfer time depends on that.

Also, in each cordless telephone in the conventional system, since the call channel is not connected to the master unit, the state of each cordless telephone cannot be known by other telephones.

  The conventional problems to be solved are as follows: (1) If the line usage status of the master unit or other slave units is not wirelessly connected (standby or the like), there is no status display, so it is impossible to grasp the status of the line usage. (2) When the external device is called for incoming calls (holding transfer) or when trying to capture the external line by verbal transfer, it takes time to transfer because it requires wireless connection control each time. .

As described above, in a conventional cordless telephone device, a call channel is temporarily opened for a cordless telephone that has received an incoming call but has not responded. Therefore, there was a problem that it took a long time to connect the recall call. In addition, since the communication channel is open, there is a disadvantage that the state of the line is not known.

SUMMARY OF THE INVENTION An object of the present invention is to provide a cordless telephone device that can shorten the connection time for transfer and can perform high-speed transfer that can grasp the state of the line and display the real-time state.

  As an improvement, the present invention continues to hold the call channel connected by the first incoming call until the call is transferred after the incoming call which requires the use status of the line in the cordless telephone. The continuous holding time of the call channel can be changed by setting, and the balance with the battery holding time can be adjusted.
