DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a time correction method for a mobile communication terminal having a telephone calling function and a time display function, and more particularly to a time correction method for a mobile communication terminal using the absolute time of a telephone network.

[0002]

2. Description of the Related Art Conventionally, there is no particularly automatic method for correcting a time in a mobile communication terminal having a telephone calling function and a time display function, and a person corrects the time based on time notification information in a media or a telephone service. It is common.

[0003]

In this conventional time correction method, since a person adjusts the time while checking the time with his or her eyes or ears, it is difficult to match the standard time perfectly even if the nerves are concentrated. Work. On the other hand, in a social environment that is becoming increasingly busy and globalized, especially in the business world, it is increasingly required to secure accurate time.

[0004] It is an object of the present invention to provide a method for accurately and easily correcting the time of a mobile communication terminal using a hard clock that outputs an absolute time in a telephone network, and to eliminate the need for an ultra-high precision clock function. It is another object of the present invention to provide a time correction method in a mobile communication terminal that facilitates the realization of a future wristwatch-type mobile terminal by reducing the number of components.

[0005]

A time correction method for a mobile communication terminal according to the present invention is a time correction method for a mobile communication terminal having a telephone calling / receiving function and a time display function. And a time transmitting means for outputting, by a PB (Push Button) signal, a predetermined specific code and initial setting time data indicating a time to be initialized at predetermined time intervals, and the mobile communication terminal receives the PB signal. PB receiving means for encoding
Time initializing time data for storing the initial setting time data following the first specific code among the codes received by the PB receiving means in time data storing means and instructing time initial setting when the next specific code is received. Setting means, time increment means for receiving the time initial setting instruction, starting time increment using the initial time data accumulated in the time data accumulating means as an initial time, and incrementing the time by the time increment means A time display unit for displaying a time to be performed, and an initialization completion notification unit for outputting a notification of completion of the time initialization in response to the time initialization instruction.

Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing one embodiment of the time correction method in the mobile communication terminal of the present invention.

In this embodiment, as shown in FIG. 1, a mobile communication terminal 1 having a telephone calling function and a time display function, a time initial setting unit 10 in the mobile communication terminal 1, and an exchange 2
And the time sending unit 3 and the receiving trunk 4 in the exchange 2
And a mobile communication network 5, of which a portion related to the present invention is a time initialization unit 1 of the mobile communication terminal 1.
0 and the time sending unit 3 on the exchange 2 side.

FIG. 2 is a block diagram of an example of the time initial setting section in FIG. The time initial setting unit 10 receives a PB signal from the exchange side and encodes the PB signal.
The time data storage unit 1 stores the initial time data following the start code received first from the code received by the B receiving unit 11.
3 and a time initial setting unit 12 for instructing a time initial setting when the next start code is received, and an initial setting time data stored in the time data storing unit 13 when the time initial setting instruction is received. Time stepping means 14 for initializing and starting time stepping, time display means 15 for displaying the time stepped by the time stepping means 14, and completion of time initialization upon receiving a time initialization instruction Setting completion notifying means 16 for outputting a notification of time, and a time correction receiving means 16 for receiving a time initial setting request from the mobile communication terminal and instructing the time initial setting means 12 to start and controlling the time stepping means 14 to stop stepping. Consists of

FIG. 3 is a block diagram of an example of the time transmitting section in FIG. The time sending unit 3 is located on the exchange side, and sets an absolute time at a predetermined time interval, for example, an absolute time in units of 10 seconds starting from 0 second together with a start code and absolute time data after the next 10 seconds, that is, initial time. The time transmission control means 31 instructs to output the set time data according to a predetermined protocol, and the PB transmitter 32 outputs the code data instructed by the time transmission control means 31 as a PB signal.

FIG. 4 is a diagram for explaining the operation of this embodiment. First, as a first step, as shown in FIG. 4A, the user goes off-hook on the mobile communication terminal 1,
It is connected to the receiving trunk 4 of the exchange 2 via the mobile communication network 5.

Next, as shown in FIG. 4B, when a predetermined service number is dialed as shown in FIG. 4B, the exchange 2 connects to the time transmitting unit 3.

In the third step, the mobile communication terminal 1 sets the start code transmitted by the time transmission control means 31 in the time transmission unit 3 via the PB transmitter 32 at a time interval, in this example, every 10 seconds. And the initialization time data. This operation state is shown in FIG.

In the fourth step, as shown in FIG. 4D, since the mobile communication terminal 1 is in the time correction state,
The time is corrected using the time initial setting unit 10 based on the received “date, time, minute, second” code data. First, when the time correction receiving means 17 is instructed to start time correction when dialing a service number in the second step, the time correction setting means 12 is activated and the time stepping means 14 is stopped.
The PB receiving means 11 encodes the received PB signal and sends it to the time initial setting means 12. The time initial setting means 12 sequentially stores the code data (1210 15 30) of "date, time, minute and second" following the start code (*) received first, in the memory (not shown) of the time data storage means 13, and When the start code (*) is received, the time stepping means 14 and the initial setting completion notifying means 16 are driven. The time stepping means 14 reads the time data accumulated by the time data accumulating means 13 and internally sets the time data and starts the stepping. The time display means 15 constantly displays the time data of the stepping on a display unit (not shown). The initial setting completion notifying unit 16 notifies the user of the completion of the initial setting by using a buzzer or a lamp (both not shown).

In this embodiment, the time interval between the start code continuously transmitted from the time sending unit 3 and the start code in the initialization time data is assumed to be 10 seconds. The optimum value should be selected in consideration of the transfer capability of time data and the like.

After the initial setting completion notifying means 16 notifies the user of the completion of the initial setting, it is necessary to automatically disconnect the line from the system or to allow the user to disconnect the line. Not stipulated.

[0016]

As described above, the time correction method in the mobile communication terminal according to the present invention allows the absolute time data in the telephone network to be received by the PB signal and automatically set, thereby enabling time correction. In addition to being able to perform easily and accurately, it eliminates the need for an ultra-high-precision clock function, and it is possible to reduce the number of parts, thereby facilitating the realization of future wristwatch-type mobile terminals.
