The present invention provides a dialing method of a multi-channel access (MCA) type wireless telephone, which allows a user to make a normal call immediately by quickly dialing without waiting for a dial tone after the user leaves the call mode on a mobile device. A dialing method of a radio telephone.

In general, a wireless telephone is composed of a base unit and a handset unit. 1 is a configuration diagram of a radiotelephone, in which FIG. 1A is a fixed device, and FIG. 1B is a configuration diagram of a portable device. In this case, wireless communication is performed between the portable device B and the fixing device A through the antenna ANT, and wired communication is performed through the lines L1 and L2 of the line interface 19 during the exchange period with the fixing device A. Will be done. Therefore, since the radio communication is performed between the portable device B and the fixed device A through the antenna ANT, the output data is modulated by the Tx units 16 and 26 and output as an RF signal, and the Rx units 14 and 24 are used. ) Demodulates the received RF signal and applies it to the microcomputers 12 and 22. At this time, the PLL unit 15.25 supplies a clock for modulation and demodulation to the Rx units 14 and 24 and the Tx units 16 and 26.

A password is also specified between the portable device B and the fixing device A to prevent theft of another person, which is designated by key input through the ID switches 13 and 23. In the fixed device A, a line interface 19 is mounted to perform wired communication through a telephone line, and there is a DTMF generator 17 and a pulse generator 18 for dialing.

Its configuration is well-known in the fact that it is already filed in the patent application number 89-8145 by the same applicant and published in the publication number 92-1544, and a detailed description thereof is omitted.

Looking at the conventional dialing function in the wireless telephone having the above-described configuration, when the call selection switch of the keyboard 21 of the portable apparatus B is turned on in the wireless telephone adopting the MCA method, the micom ( 22) This process (2f) detects this and has an empty channel for transmitting data. If an empty channel is found in the process, the channel is fixed and the call information controlled for the call is transmitted in step 2g.

The microcomputer 12 of the fixed device A always looks at all channels, and if one empty channel to be used is found, whether the mobile device B receives the call information transmitted in the process (2g) from the channel. Monitor in (2a).

From the received data, it is determined that the password is from the same mobile device B, and when the same password is used, the current channel being searched is fixed as the used channel. The response information about the received call information is transmitted through the Tx unit 16 in step 2b.

On the other hand, the microcomputer 22 of the mobile device B, which continues to transmit the call information, checks whether or not the response information transmitted from the fixed device A is received through the Rx unit 24 in step 2h. do.

If the reception of the response information is confirmed in step 2h, the microcomputer 22 of the portable apparatus B stops transmitting the call information. Then, in step 2i, the dial key input through the keyboard 21 is checked to enter the call mode if there is an input. That is, from this time on, it is recognized that the input of the dial key is valid as the ratio of step (2i), and the dial information according to the dial key input on the keyboard 21 is then processed by the microcomputer 22 of the portable device B to execute the Tx unit. In step (2j) through (26). The microcomputer 12 of the fixing device A, which has received the dial information through the antenna ANT and the Rx unit 14 of the fixing device A, inputs the dial information to the DTMF generator 17 to provide a dial DTMF signal. It generates and outputs through the line interface 19 to perform the dialing process (2d).

As described above, the input of the dial key is ignored in the mobile device B during the channel search and call information communication time, i.e., before the dial tone is heard, and even if there is an input, the dial key has to be input again from the beginning.

As described above, the dial key input during the channel search and information communication time is ignored, which may cause confusion in pressing the dial key, and may cause a dialing error due to incorrect dialing.

Accordingly, an object of the present invention is that even if there is a dial key input before turning on the call switch of the portable device and listening to the dial tone in the MCA type wireless telephone, it is stored and generated until the dial tone is heard at the same time as the dial tone is generated. The present invention provides a method for providing convenience to a user by allowing the user to immediately press the dial key without waiting for a time waiting for the dial tone by dialing the stored dial key value in sequence.

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

3 is a flowchart according to the present invention, the specific embodiment of FIG. 3 will be described with reference to FIG. 1, and the Tx units 16, 26 of the portable device B and the fixing device A of FIG. The "MC 2833" of "US Motor Roller", the Rx units 14 and 24 are the "MC 3362" of the said company, and the PLL circuits 15 and 25 are possible if it is the "MC 145168" of the said company. As the microcomputers 12 and 22, a microcomputer "HD 4074019" manufactured by Hitachi, Japan, is used.

FIG. 3A is a flowchart in the fixing device A at the same level as in FIG. 2B, and 3B is a flowchart in the portable device B according to the improved invention.

When the mobile device (B) selects a call switch for dialing, it transmits control call information for dialing and a call to the fixed device (A) to form an RF link between the mobile device (B) and the fixed device (A). In response to the normal reception of the call information from the fixing device (A) for transmitting the response information to the portable device (B) to check whether the portable device (B) receives the response information corresponding to the dial tone And a second step of recording, if there is a dial key input information before the portable device B receives the response information in the first step, and recording the dial key input information in a recording area provided for dialing information; If there is response information received from the fixing device A in the second step, the previously stored dial information is first transmitted to the fixing device A before receiving the response information. And the dial key information input continuously input after the response information is received from the fixing device A of the third step. After confirming and transmitting to the fixed device A as in the third process and dialing, if there is no input dial key information and the call switch is off, the call end information is transmitted to the fixed device A, and then the call is made. The fourth process is to complete.

Therefore, a specific embodiment of the present invention will be described in detail with reference to FIGS. 1 and 3, when the call switch of the portable device B is turned on, the microcomputer 22 of the portable device B is connected to (3f) of (3A). Checks the call switch on state. In step (3f), when the call is switched on, the PLL circuit 25 is controlled to transmit the call information to the antenna ANT through the Tx unit 26 to control the RF link formation.

The microcomputer 22 of the portable apparatus B initializes a dial input pointer, a dial sending pointer, and a dial sending buffer required for dialing out to an internal constant buffer as shown in (4a) to " 0 ".

The call information transmitted from the portable device B in the process (3g) is received by the microcomputer 12 through the Rx unit 14 through the antenna ANT of the fixed device (A). The microcomputer 12 of the fixing device A checks whether normal call information is received in step 3a. When the call information is received in step (3a), the response information is transmitted to the mobile device (B) through the antenna (ANT) through the Tx unit 15 as a signal indicating that normal call information is received in step (3b). do. After the transmission of the response information, the fixing device A initializes a dial input, a delivery pointer, and a dial buffer required for dialing, as shown in (4b).

The response information sent from the fixing device A is input through the Rx unit 24 of the portable device B so that the microcomputer 22 checks whether the response information is received in step 3h.

In the present invention, the mobile device B selects the call selection mode and simultaneously inputs a key for dialing irrespective of the dial tone signal input to enable a normal call. Therefore, in the portable apparatus B, the call switch of step (3f) is turned on, and after the call information of step (3g) is transmitted, that is, before the response information is received in time, the keyboard 21 continues to be dialed for quick dialing. Anyone can have a desire to enter a dial key. In the related art, when the dialing is performed, the key input has been dialed or ignored, and the present invention has to be dialed again. After turning on the call switch, check whether the dial information is the key information continuously input through the keyboard 21 in step 3i. If the dial key information is the dial key information, the dial input pointer of FIG. The pointed key stores the key input information value in the dial transmission buffer, and continues to input dial key information while increasing the dial input pointer.

That is, if the dial buffer is empty before the dial key information input as shown in (4c), but the dial keys are entered in order of "1", "2", and "3", the dial key information input storage example is shown in FIG. As shown in 4d), the dial input pointer is incremented, and the dial dispatch pointer is in the initial state because it is before the dispatch.

As described above, when there is reception of the response information transmitted from the fixing device A while the dial key information is being recorded, the microcomputer 22 of the portable device B transmits the dial information value to the dial sending buffer of the fourth degree in step 3k. Check if there is any.

As in the example of (4d), since the " 1 ", " 2 " and " 3 " is read, the dial information stored in the process (3I) is read while increasing the dial output pointer as shown in (4e) and fixed by the Tx unit 26. Send to (A).

The fixing device A receives the dial information sent from the portable device B through the Rx unit 14 and checks whether the dial information is received in step 3c. Upon reception without error, the microcomputer 12 performs dialing in step 3d.

The internal dial transmission buffer of the microcomputer 12 of the fixing device A is empty as shown in (4F), and when the dial information is received in the process (3c) and it is stored, it receives and stores 1 as shown in (4g). In this case, the dial execution pointer is always located one digit before the dial input pointer, and receives the dial information stored before the response signal is received in step (3h), and continues to enter the portable device B thereafter. The stored information is transmitted to the fixing device A in the same manner as described above, and dialing is performed in the process (3d) of the fixing device A.

That is, as shown in (4g), the dial execution buffer of the microcomputer 12 of the fixing device A reads the dial information as the dial execution pointer increases as the dial input pointer increases before one digit of the dial execution pointer, and reads the DTMF generator ( 17) to transmit the dial DTMF signal via the line interface 19 to dial. The dial information input after the response information signal is received by the portable apparatus B is checked at step 3m if the key is input, and stored at the dial transmitting buffer at step 3n to be stored in the portable apparatus B. The dial information is sent to the fixing device A while passing through 3k and 3l as described above.

If all the dial information is sent from the portable device B to the fixing device A without the dial key, the dial input buffer is the same as the dial input pointer as shown in (4h). There is no further input of dial key information into the microcomputer 22 of the portable device B, and from the dialing it is normally in a call state with the caller. If the call is detected after the call or the call is terminated, the user turns off the call switch on the keyboard 21 of the portable apparatus B. FIG.

The microcomputer 22 of the portable device B checks the call switch-off in step 3o, and transmits call end information to the fixed device A through the Tx unit 26 in step 3p. The fixing device A is received by the microcomputer 12 through the Rx unit 14 and checked in step 3e.

By dialing in this way, the input of all dial keys is effective after turning on the call switch, i.e., before receiving a dial tone signal, so it is inconvenient to enter a dial key only after turning on the conventional call switch and forming a call path and listening to the dial tone. Since it is possible to solve the problem, quick dialing can be realized.

As described above, by turning on the call switch of the mobile device and ignoring the dial key input before the call path is formed, it is stored in the buffer and dialed to alleviate the inconvenience of waiting for the call to be established. There is an advantage to this.
