Method for transmitting a predetermined message of the telephone system}

The present invention relates to a message reservation transmission method of a telephone system, and more particularly, to a message reservation transmission method of a telephone system for creating and storing a message in which a reservation time is set in a telephone and transmitting the created message through a PSTN network when the reservation time is reached. It is about.

In general, mobile communication systems have been rapidly developed as the industrial society has spread rapidly. Especially in the early 1980s, in North America, the service area was divided into hexagonal cells of several km to several ten kilometers in diameter, and then in the geographically separated cells. The mobile communication system has grown rapidly by using a cellular mobile communication system that uses the same frequency channel repeatedly and implements a radio channel switching function between cells as the subscriber moves. In recent years, wired and wireless telephones, which have a built-in wireless transmission / reception function in a general telephone and are used in link with a mobile communication terminal, have also been rapidly spread and used.

Then, referring to the conventional wired / wireless telephone as described above with reference to FIG. 1, a fixed device 72 having a built-in wireless circuit unit (not shown) connected to the PSTN network 70 and executing a voice call through the switch 71 is provided. And a portable device 73 which transmits and receives a communication signal wirelessly with the fixing device 72.

Then, the fixing device 72 processes a communication signal transmitted as a wireless signal from the portable device 73 and transmits it to the switch 71 through the PSTN network 70. Accordingly, the exchange 71 analyzes the telephone number input from the fixing device 72 of the individual telephone and applies the ring signal to the telephone 74. When the user of the counterpart phone 74 hooks off, a call is formed between the phones 72 and 74. At this time, a telephone call is performed through which the normal voice signal is transmitted and received.

However, since the conventional wired / wireless telephone is operated only by a function of transmitting and receiving a voice call through the PSTN network, a user's desired service such as text message transmission cannot be performed at all. Even if there is a text message transmission function, there is a problem that the functionality of the phone is also deteriorated accordingly because there is no reservation function.

Accordingly, the present invention has been invented to solve the above-mentioned conventional problems, by creating and storing a message set a reservation time in the phone, and when the time reaches the reservation time, the user of the phone by transmitting the message through the PSTN network It is an object of the present invention to provide a message reservation transmission method of a telephone system, which can transmit a message in a time zone intended by the user, thereby greatly improving the convenience of the telephone.

Another object of the present invention is to provide a reservation method for transmitting a message in a telephone system, in which a short message can be reserved and transmitted from a telephone through a PSTN network.

In order to achieve the above object, the present invention provides a message creation step of creating a message according to a set menu when a message creation function is set in a phone, and a reservation for checking whether a current message reservation transmission function is set after the message creation step. And a reservation transmission time setting step of setting a reservation transmission time of the currently created message and starting counting reservation time when the setting of the current message reservation transmission function is confirmed by the transmission setting confirmation step and the reservation transmission setting confirmation step; The present invention provides a reservation method for message transmission in a telephone system, comprising a reservation message transmission step of transmitting a pre-written message through a PSTN network at a preset reservation time when the transmission reservation time is reached after the transmission time setting step.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The apparatus to which the present invention is applied includes a memory unit 1 for storing other information including a user's input message signal and a message transmission reservation time, and a message signal stored in the memory unit 1 as shown in FIG. A microcomputer (2) for controlling overall functions of the telephone, including a function of transmitting the data at a scheduled transmission time, a modem (3) for modulating and demodulating a communication signal input and output according to the function control of the microcomputer (2); PSTN network is connected between the RF unit (5) and the modem (3) and the PSTN network (6) for processing the RF signal received through the modem (3) RF signal processing for transmission to the portable device (4), for example (6) a voice interface connected to the signal interface unit 7 and the signal interface unit 7 for interfacing the transmission signal input and output through the signal and performing constant signal processing, for example, noise removal, and the like. Signal is D (Digital) / A (Analog) ) And a codec (9) and, LCD (10) to one end is connected to the output of the display signal of the microcomputer (2) for conversion or A / D conversion.

One end of the microcomputer 2 is connected to a key panel unit 11 for inputting a user's function setting.

Next, the method of the present invention applied to such a telephone will be described.

As shown in Fig. 3, the present invention proceeds to the message creation function setting determination step S2 in the initial state S1 to determine whether the message creation function is currently set in the telephone. At this time, if it is determined during the message creation function setting determination step (S2) that the message creation function is not set, the process proceeds to the general call function execution step (S3) to execute the normal telephone call mode.

That is, when a communication signal is input to the PSTN network 6 through the external switch 12, this communication signal is interfaced by the signal interface unit 7 of the telephone 13, and then subjected to constant signal processing, for example, a noise removing process. It is input to the modem 3. Then, the modem 3 demodulates the input communication signal and outputs it to the codec 9 and the RF unit 5. The codec 9 converts the digital communication signal input according to the control signal of the microcomputer 2 into an analog signal and outputs the signal to the handset 8. At this time, when the user lifts the handset 8, the counterpart phone 14 ), You will hear a voice signal so that you can make a normal call. At the same time, the RF unit 5 processes the input communication signal according to the control signal of the microcomputer 2 and transmits the RF signal to the portable device 4.

On the contrary, when making a call to the external telephone 14 through the PSTN network 6, a telephone number signal is inputted through the key panel unit 11, in which the communication signal is processed in the opposite manner to the counterpart telephone. The call is inputted at 14. At this time, the process of the phone 13 is displayed by the microcomputer 2 as predetermined numbers, letters or graphics (or moving picture) information on the LCD 10.

On the other hand, if it is determined during the message creation function setting determination step (S2) that the message creation function is set, the process proceeds to the message creation step (S4) and creates a message according to the menu set in the telephone. At this time, the message type includes a short message or an email.

After the message creation step S4, the process proceeds to the reservation transmission setting determination step S5 to determine whether the current message reservation transmission function is set. At this time, if the current message reservation transmission function is set as the result of the determination during the reservation transmission setting determination step (S5), the process proceeds to the reservation transmission time setting step (S6) to set the reservation transmission time of the currently created message and starts the reservation time counting. do.

In addition, after the reservation transmission time setting step S6, it proceeds to the transmission reservation time checking determination step S7 to determine whether the current time P has reached the transmission reservation time ST. When the current time P does not reach the transmission reservation time ST as a result of the determination in the transmission reservation time checking determination step S7, the current step S7 is repeated. However, when the current time P reaches the transmission reservation time ST as a result of the determination during the transmission reservation time checking determination step S7, the process proceeds to the reservation message transmission step S8 to reserve the pre-written message. Transmit via PSTN network in time.

On the other hand, if it is determined during the reserved transmission setting determination step (S5) that the current message reservation transmission function is not set, the message transmission step (S9) proceeds to send the currently created message immediately through the PSTN network.

That is, when the user of the telephone 13 wants to transmit a message using the PSTN network 6, the user can set the message writing menu through the key panel unit 11, and the microcomputer 2 recognizes this and the LCD The corresponding function is indicated through (10). Then, the user sets the transmission information such as the recipient's telephone number or the reply number according to the menu screen displayed on the LCD 10, and the desired message, for example, a text message or an email message through the key panel unit 11. Write. At this time, the microcomputer 2 of the telephone 13 stores a message written by the user through the key panel unit 11 in the memory unit 1. Then, the microcomputer 2 asks whether to send the current written message through the LCD 10 or reserve the message immediately. At this time, if the user requests transmission now, the microcomputer 2 establishes a call with the mail server 15 through the exchange 12 using the recipient phone number (OR Email address), and then returns to the server 15. When a message reception ack signal is received, the message signal stored in the memory unit 1 is processed through the modem 3 and the signal interface unit 7, and then transmitted to the mail server 15 through the PSTN network 6. .

On the other hand, in the process, if the user wants to send a reservation message, the microcomputer 2 displays the reservation time input menu screen via the LCD (10). The user of the telephone 13 sets the scheduled transmission time of the message through the key panel unit 11 while looking at the LCD 10. Then, the microcomputer 2 stores the transmission reservation time of the message set by the user in the memory unit 1 and starts checking. In the process, the microcomputer 2 automatically off-hooks a call through the exchange 12 when the current time P reaches the scheduled transmission time of the message set by the user. When the message receiving ACK receiving signal is received from the server 15 by the switching of the switch 12, the microcomputer 2 transmits the message signal stored in the memory unit 1 to the modem 3 and the signal interface unit 7. After processing the predetermined signal through the PSTN network (6) and transmits to the server 15. Then, the server 15 transmits a signal indicating whether the message has been successfully received to the phone 13 through the PSTN network 6. Then, the microcomputer 2 of the phone 13 displays a signal indicating the success of the message transmission through the LCD 10 in accordance with the signal of the server 15. At this time, the server 15 transmits a signal indicating that the message has arrived to the recipient in the usual manner.

As described above, the present invention creates and stores a message in which a reservation time is set in the phone, and when the reservation time is reached, the user of the phone can transmit a message in a time zone intended by the user through the PSTN network. Therefore, it has the advantage of significantly improving the convenience of the phone accordingly.

In addition, according to the present invention, since the short message can be reserved and transmitted from the telephone through the PSTN network, the functionality of the telephone is also significantly improved.
