As shown in step 15, a "link channel establishment phase" is established between the calling side and a PHS network including the ISDN network (hereinafter, referred to as a PHS network), and a line is connected between the calling side and the PHS network. Further, a "link channel establishment phase" is established between the PHS network and the called side as shown in step S16, and a line is connected between the PHS network and the called side. Eventually, a line is connected between the calling side and the called side. Therefore, data including a text message is transmitted from the transmitting side to the receiving side.

Here, the character message is stored at the destination subaddress in the transmission data. FIG. 6 shows the data format of the destination sub address. As shown in this figure,
The destination sub-address has one octet of 8 bits and 1
Octets are the destination subaddress information element identifier area, 2 octets are the destination subaddress content length area, and 3 octets are the extension / subaddress type / E / O / reservation area. The second generation cordless telephone system standard R
According to CR STD-28, in the present invention 4 to 23
Octets are used as character information areas. The text message is stored in 4 to 23 octets in a relation of 1 octet = 1 character. Therefore, a text message can be transmitted in a total of 20 characters.

When the character message (character information) stored and transmitted in the destination sub-address is received in this way, the received character message and caller telephone number are stored in the memory as shown in step S17, and furthermore, If the simultaneous display mode is set, the images are simultaneously displayed on the display unit as shown in step S18. Step 1 above
The operations up to 8 are normally performed during a non-communication state, and all the text messages transmitted from the calling side are received. After the text messages are stored in the memory, the line with the calling side is disconnected. However, if a response is made at the same time while viewing the display on the display unit in step S18, the user can turn on the response key as shown in step S19 to make a call with the caller. When the call is over, the line with the calling side is disconnected.

FIG. 5 is a flowchart showing the operation when the text message received on the receiving side as described above is further transferred to another telephone. When the received text message is transferred from the called party to another telephone, if the received text message is displayed on the display unit, the transfer operation is immediately performed as shown in step S32. On the other hand, when the received character message is not displayed on the display unit, first, as shown in step S31, a read operation is performed to read the received character message stored in the memory from the memory and display the received character message on the display unit. Then, a transfer operation is performed as shown in step S32. Next, the telephone number of the transfer destination (destination) telephone is input as shown in step S33. Thereafter, as shown in step S34, a calling operation using a calling key is performed. Then, the line between the called side and the transfer destination telephone is connected via the PHS network in exactly the same way as the case of the calling side and the called side in FIG. The message is transmitted, the text message is stored in the transfer destination telephone, and, if the simultaneous display mode is set, simultaneously displayed on the display unit. The detailed description of this part is exactly the same as the operation on the receiving side in FIG.

When the received and stored text message is transferred from the called party to the transfer destination telephone, a new text message can be added to the text message. It is also possible to edit a text message received one character at a time. To explain this point in detail, a plurality of additional character messages are created and stored in a memory (RAM) in advance.
M) can be read and added to the received stored text message. That is, the received message can be transferred after being edited. In addition, a plurality of transfer destination telephones to which the text message is transferred can be used, and the text messages can be automatically transferred to the plurality of telephones automatically using a timer in the CPU. Further, when the text message does not reach the transfer destination telephone during the busy or outside of the area, that is, when the transfer fails, the transfer operation can be repeatedly performed using a timer in the CPU. Further, the input of a telephone number can use a shortening function, a one-touch dial function, a telephone directory function, and the like. In the above embodiment, the present invention is applied to a PHS. However, the present invention is applicable not only to a mobile phone and an automobile phone but also to a DTMF (Dual-Tone-Multi-Frequency) signal if it has a character transmission function. If a character transmission using a combination of a code or a PB (push button) signal is used, it can be applied to an ordinary wired telephone.
