The present invention relates to a mobile communication terminal, and more particularly, to a time setting method for setting an internal time of a mobile communication terminal and a mobile communication terminal accordingly.

With the development of technology, functions for user convenience provided in a mobile communication terminal are becoming more diverse. In particular, as the roaming service for foreign travelers is commercialized, the importance of the function to set the internal time of the mobile communication terminal to meet the local time zone is emerging.

In general, in the synchronous mobile communication method, the mobile communication system broadcasts the visual information in the broadcasting information periodically. Therefore, whenever a mobile communication terminal receives the broadcasting information transmitted from the mobile communication system, the mobile communication terminal sets a time using the broadcasting information, so that the mobile communication terminal matches the local time zone regardless of time zone fluctuation. A service using information can be provided to a user.

However, unlike the synchronous mobile communication system, the asynchronous mobile communication system does not periodically provide visual information to the mobile communication terminal. Accordingly, when the asynchronous mobile communication terminal runs out of battery power or moves to a local time zone, the asynchronous mobile communication terminal cannot provide a user with a service using time information that matches the current time or local time zone.

In order to solve this problem, a technique for setting a time of an asynchronous mobile communication terminal using a short message service (SMS) has been conventionally proposed.

In more detail, the US Patent Application No. 2004/0023681 filed under the name "THE FOR SYNCHRONIZING THE INTERNAL CLOCK OF A MOBILE RADIO TERMINAL WITH LOCAL TIME" by the US Patent and Trademark Office discloses that the mobile communication terminal has its own SM ( When the Short Message (SMS) is transmitted, the Short Message Service Center (SMSC) receiving the SM transmits a time stamp to the terminal, and transmits the time stamp to the terminal. Disclosed is a technique for setting a time by comparing information with time information counted by a mobile communication terminal.

However, the above-described conventional technology inherently hassles in using a user to directly transmit an SM to set the time whenever a time is required, and the mobile communication terminal must transmit the SM. There was a problem that could occur.

Accordingly, when the time setting of the asynchronous mobile communication terminal needs to set the time, it is urgently required to develop a technology that can automatically set the time without a user's operation and can also generate unnecessary billing.

Accordingly, an object of the present invention is to provide a time setting method for automatically setting a time corresponding to a current time by a mobile communication terminal of an asynchronous mobile communication method, and a mobile communication terminal according thereto.

To pass. The RL transmits an SMS message provided by the TL through an LL or provides an SMS message received through the LL to the TL.

Operation of TL and RL among the plurality of layers will be described with reference to FIG. 1, which shows a general SMS procedure.

When the TL of the mobile communication terminal provides the SMS message received from the AL to the RL (step a), the RL wirelessly transmits the SMS message to the SMSC (step b).

When the SMS message is received from the mobile communication terminal, the SMSC checks whether the received SMS message is normal and provides an acknowledgment message (Ack / Error) indicating this to the mobile communication terminal (step c). The RL of the mobile communication terminal transmits the reception report message to the TL (step d).

Here, the SMSC includes time information (TP service center time stamp) in a reception report message that reports whether or not the SMS message transmitted by the transmitting mobile terminal is normally received. The time information is shown in FIG. It is composed together.

Referring to FIG. 2, the time information includes information on year, month, day, hour, minute, second, and time zone, and 2 [Digits] is allocated to each information.

On the other hand, the SMSC transmits the SMS message provided by the transmitting mobile terminal to the receiving mobile terminal (step e).

The RL of the receiving mobile terminal transmits the SMS message transmitted by the SMSC to the TL, and the TL guides the SMS message to the user through the AL (step f). In addition, the TL of the mobile terminal of the receiving side provides the SMSC with a reception report message (Ack / Error) indicating normal reception of an SMS message through the RL (steps g and h).

As described above, the SMSC notifies the mobile communication terminal by including time information in a reception report message confirming whether the SMS message is normally received by the mobile communication terminal that has sent the SMS message.

Accordingly, when a time setting is desired, the mobile communication terminal of the present invention transmits an SMS message for acquiring time information including an abnormal SMS message to the SMSC, and the SMSC receiving the abnormal SMS message receives a reception report message (Error). The time information is included in the message and transmitted to the mobile communication terminal.

The mobile communication terminal receiving the reception report message sets a time by using the time information included in the reception report message, and the SMSC does not perform an SMS because the SMS message is abnormal. There is no charge for sending SMS messages.

The abnormal SMS message may be a non-existent number of TP-DA (TP Destination), which is the number of the receiving mobile terminal, or a non-existent number of TP-PID (TP Protocol Identifier), which is network identification information. This can be

The configuration of the SMS system according to the first preferred embodiment of the present invention will be described with reference to FIG.

The mobile communication terminal 100 transmits an abnormal SMS message for acquiring time information to the SMSC 200 when a situation in which time setting such as power on or time zone change is desired occurs, and transmits the abnormal SMS message to the SMSC 200. When the reception report message for the SMS message is provided, the internal time is set based on the time information included in the reception report message.

The base station controller (BSC) / base station transceiver system (BTS) performs signal and call processing with the mobile communication terminal 100, and the mobile switching center (MSC) / visit location register (VLR) 208 Performs exchange function for SMS processing by interworking.

The MC 204 is responsible for SMS processing and interworking between the SMS server 202 and the MSC / VLR 208. In particular, when a normal or abnormal SMS message is received, the MC 204 transmits a reception notification message for guiding reception status (Ack / Error) for the SMS message to the corresponding transmitting-side mobile communication terminal 100.

The HLR (Home Location Register) 206 is a database that provides subscriber information necessary for call processing.

Now, the visual reset procedure according to the first preferred embodiment of the present invention applicable to the mobile communication system will be briefly described with reference to the procedure diagram of FIG.

When the time reset is requested, the TL of the mobile communication terminal 100 transmits an abnormal SMS message set in advance for obtaining time information to the SMSC 200 through the RL (steps A and B).

Upon receiving the abnormal SMS message, the SMSC 200 provides a reception report message indicating an error to the mobile communication terminal 100 when the abnormal SMS message is received, and does not perform any further SMS processing. In particular, the SMSC 200 inserts time information into the reception report message (steps C and D).

The mobile communication terminal 100 receiving the reception report message in which the time information is inserted resets an internal time based on the time information.

As such, the present invention automatically transmits an abnormal SMS message only when the mobile communication terminal 100 needs to reset the time, and receives the reception report message according to the transmission to reset the time. Therefore, the present invention can set the time of the asynchronous mobile communication terminal 100 according to the current time of the local time zone without change in the processing procedure of the mobile communication system including the SMSC 100.

Or to read the abnormal SMS message from the memory unit 104 to the SMSC 200 to set a time when the time zone information received from the BSC / BTS 210 is changed, and provides the SMSC 200 according to the abnormal SMS message. When the SMSC 200 provides a reception report message indicating an error, the control unit 102 calculates a current time based on the time information inserted in the reception report message, and the time of the timer 106 is calculated using the calculated current time. Reset it.

In addition, the control unit 102 periodically performs the time setting procedure according to the user's setting or the like, or performs the time setting procedure using the reception report message provided from the SMSC 200 whenever the user sends an SMS message. When the user's time setting request is generated, the time setting procedure may be performed.

The memory unit 104 stores a variety of information including the control program of the control unit 102, and particularly stores an abnormal SMS message for acquiring the time information according to the preferred embodiment of the present invention. The abnormal SMS message for acquiring the time information is set to an inappropriate value such as TP-DA, the number of the receiving mobile communication terminal, and TP-PID, the network identification information. Accordingly, the SMS message for acquiring the time information is normally transmitted. It doesn't work.

The data is read from the unit 104 and transmitted to the SMSC 200, and the transmission time information is stored in the memory unit 104 (step 304).

After transmitting the abnormal SMS message for acquiring the time information, the controller 102 checks whether a reception report message according to the receipt of the SMS message for acquiring the time information is provided from the SMSC 200 (step 306).

When the reception report message is provided from the SMSC 200, the reception time of the reception report message is stored in the memory unit 104, and the time information inserted in the reception report message is extracted (step 308).

When the time information is extracted, the controller 102 corrects the time according to Equation 1 by using the values TS and TR obtained through a transmission time of an SMS message for receiving time information, a reception time and a test of a reception report message, and the like. Calculate the value. Here, the TS is a value until the SMS message for obtaining time information is transmitted from the mobile communication terminal to the SMSC, and the TR is a value until the reception report message is transmitted from the SMSC to the mobile communication terminal. Obtained through the test.

T = T0 * (TR / (TS + TR))

T = time compensation value

T0 = time from the transmission time of the SMS message for receiving the time information to the reception time of the reception report message

The time correction value according to Equation 1 indicates the time when the mobile communication terminal 100 receives the reception report message from the time when the SMSC 200 inserts the current time information into the reception report message and transmits the received time message. The error range of the time correction value is 45 [Sec] or less, which is a waiting time for the reception report message set in the mobile communication terminal 100.

When the time correction value is calculated according to Equation 1, the control unit 102 calculates current time information by adding the time information extracted from the reception report message to the time correction value (step 310).

When the present time information is calculated, the controller 102 sets the time of the timer 106 to the calculated present time (step 312).

As described above, the present invention automatically sets the time using an abnormal SMS message when a time setting is required, thereby doubling the ease of use and preventing charging for the time setting.

In the first preferred embodiment of the present invention, an abnormal SMS message is used to prevent unnecessary charging, but the time may be reset by using a reception report message of the SMSC according to a normal SMS message transmission by a user. .

That is, the present invention may allow the SMSC to reset the time by using the reception report message whenever the SMSC provides the reception report message.

A second preferred embodiment of the present invention will be described with reference to the flowchart of FIG.
