Embodiments of the present invention will be described with reference to the drawings. The wireless telephone system according to the present embodiment includes a first handset and a second handset of the PHS system capable of performing transceiver communication with each other. FIG. 1 is a block diagram showing a configuration of a main part of the first slave unit. The second handset has the same configuration as the first handset.

In FIG. 1, (1) is a transmitting circuit,
A signal from a baseband unit (6) to be described later is shared (2)
To the second slave unit or the public base station via the antenna (3). (4) is a receiving circuit for receiving radio waves from the second slave unit or the public base station via the antenna (2) and the duplexer (2). The duplexer (2) switches the connection of the antenna (3) to the transmission circuit (1) or the reception circuit (4). (5) is a PLL circuit which changes the transmission and reception frequencies of the receiving circuit (41) and the transmitting circuit (43).

[0008] (6) is a baseband unit, which comprises a modem (61), a TDMA processing circuit (62), and a voice codec (63).

The modem (61) performs analog / digital conversion, performs π / 4 shift QPSK modulation / demodulation processing, and performs diversity reception switching. The TDMA processing circuit (62) performs time division multiple access, time division duplex, scramble, error control, and timing detection. The voice codec (63) compresses (encodes) and decompresses (decodes) voice, and performs analog / digital conversion.

[0010] (7) is a speaker used in a portable state with a lid (not shown) closed, and converts the electric signal of the baseband section (6) amplified by the amplifier circuit (8) into sound. (9) and (10) are a speaker and a microphone used in a normal call state with the lid open. Speaker (9)
Is the baseband section (6) amplified by the amplifier circuit (11)
Is converted into voice. The microphone (10) converts sound into an electric signal. An amplifier circuit (12) amplifies the output of the microphone (10) and outputs it to the baseband unit (6).

(13) is a control circuit composed of a microprocessor. The ROM (1) stores an operation program.
Each part is controlled based on 4). Reference numeral (15) denotes a RAM, which is information necessary for the operation of the control circuit (13), for example, the slave unit number (151) of the second slave unit and the public telephone number (15).
2), the transceiver number (153) and the bell (1)
A plurality of ring sound type data (154) of 6) is stored.
(16) is a bell which sounds with a sound of the type specified by the control circuit (13). (17) is a liquid crystal display means,
Display phone numbers etc. (18) is an input means,
Enter a phone number, etc.

Next, the operation of the present invention will be described. FIG.
Is a flowchart showing the operation of the control circuit (13) of the first slave unit (call destination), and FIG. 3 shows the operation of the control circuit (13) of the second slave unit (call destination). It is a flowchart. Both the first slave unit and the second slave unit are set to wait for a control signal in the public mode and a control signal in the transceiver mode in a time sharing manner.

When the control circuit (13) of the first slave unit receives an incoming signal from the base station (S1), it causes the base station to send a link channel establishment request through the control channel. The base station receiving this transmits a link channel assignment indicating the slot to be used on the control channel. Upon receiving the link channel assignment, the control circuit (13) of the first slave unit selects a transmission slot that is not adjacent to the assigned slot as a transmission slot for incoming call transfer.

Here, as shown in FIG. 4, it is assumed that a first reception slot (R1) and a first transmission slot are allocated for communication. Then, the control circuit (13) of the first slave unit selects the third transmission slot as a transmission slot for incoming call transfer. The synchronization signal of the selected transmission slot for incoming call transfer is transmitted to the second slave unit in the transceiver mode (S2).

The second handset that has received it sets the transceiver mode to match the transmission slot for transferring the incoming call of the first handset (Y in S21, S22). Thereby, even if the first slave unit is talking in the public mode, communication between the first slave unit and the second slave unit can be performed in the transceiver mode.

The first handset rings (S3) and uses the third transmission slot (T3) in the transceiver mode to use the second transmission slot (T3).
(S4).

When the second handset receives the incoming call start signal (Y in S23), the first ringing sound in the public mode (S12).
A second ringing sound different from the above is generated (S24). In addition, the display means (17) displays that there is an incoming call to the first slave unit (S25).

When the call termination processing (S5) is completed, the first slave unit synchronizes the transceiver mode with the original standby (control channel instead of the speech channel) slot, and transmits the third transmission slot (T3) in the transceiver mode. ) Is used to send an incoming end signal to the second slave unit (S6).

When the second handset receives the incoming termination signal (Y in S26), it generates a second ringing sound and displays the display means (1).
The display according to 7) is terminated (S27). Then, the transceiver mode is synchronized with the original standby (control channel) slot (S28).

The reception of the second slave unit is performed without going off-hook.

In this way, the first slave unit can communicate with the base station and the second slave unit using the two transmission / reception slots. It can be transferred to the child device.

Since the first slave uses slots that are not adjacent to each other for communication with the base station and communication with the second slave, the first slave communicates with one PLL. be able to. For example, one PLL can change the frequency of the first slot for the base station to the frequency of the third slot for the second slave unit using the time of the second slot. If they are adjacent to each other, one PLL does not have time to switch between the frequency for the base station and the frequency for the second slave unit, and requires two PLLs.

[0023]

The incoming call in the public mode can be notified by using another PHS type telephone device.
