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

1 is a block diagram of a mobile communication terminal synchronization system according to the present invention.

As shown, the synchronization system of the present invention is connected through at least two or more mobile communication terminals (10-1 ~ 10-n), mobile communication terminals (10-1 ~ 10-n) and the mobile communication network 20, As one mobile communication terminal transmits a synchronization attempt message including at least one mobile communication terminal number, a synchronization time, and application information, request for the synchronization preparation to at least one mobile communication terminal specified in the synchronization attempt message. And, if the mobile communication terminal responds to the synchronization preparation request includes a synchronization server 30 for requesting to execute a specific application program at a specific time to the mobile communication terminal.

Each of the mobile communication terminals 10-1 to 10-n obtains a standard time (GPS satellite signal time) from the base station when the power is turned on and sets the reference time. It is possible to execute.

First, the synchronization request mobile communication terminal transmits a synchronization attempt message including the parameters shown in Table 1 below to the synchronization server 30.

TABLE 1

Message item format Remarks Synchronization point Time Reference point Application identification number Number Identification number Communication terminal identification number Number Total number Communication terminal identification number IMSI, MIN Identification number

The synchronization attempt message may be installed in a mobile communication terminal, a synchronization information transmission program is executed, a necessary item is input by executing a synchronization information transmission program, and then transmitted through an SMS method or a wireless Internet access method. The synchronization information transmission program may be installed and released when the mobile communication terminal is released, or may be downloaded and used from the synchronization server 30 after the release.

When receiving the synchronization attempt message, the synchronization server 30 compares the synchronization time point with the current time, and transmits the synchronization attempt message when the synchronization time point has already passed or is a time that the synchronization server 30 cannot process. Send an error message to the terminal. On the other hand, when the processing time is available, the requested mobile communication terminal number included in the synchronization attempt message is extracted, and the synchronization preparation message is transmitted to each requested mobile communication terminal. Here, the synchronization preparation message may be transmitted by an SMS method or a wireless Internet access method, and includes parameters as shown in [Table 2].

TABLE 2

Message item format Remarks Synchronization point Time Reference point Application identification number Number Identification number Sync request terminal identification number IMSI, MIN Identification number

Upon receiving the synchronization preparation message, the requested mobile communication terminal checks whether the corresponding application program can be executed at the corresponding time, and transmits the synchronization preparation response message as shown in [Table 3] to the synchronization server 30. In addition, when the application can be executed, the transition to the standby state.

TABLE 3

Message item format Remarks Can I sync? Yes / No

When the received synchronization server 30 receives the synchronization preparation response message from all of the requested mobile communication terminals, the synchronization server 30 checks whether the synchronization is possible, and transmits a synchronization start message as shown in Table 4 to the mobile communication terminal that can be synchronized.

TABLE 4

Message item format Remarks Synchronization point Time Reference point Application identification number Number Identification number Sync request terminal identification number IMSI, MIN Identification number

Then, the mobile device having received the synchronization request mobile communication terminal and the synchronization start message executes the corresponding application program at the corresponding synchronization time point.

On the other hand, as a result of checking the synchronization preparation response message received from the requested mobile communication terminal, if there is a mobile communication terminal that can not be synchronized, the synchronization server 30 is impossible to synchronize including the mobile communication terminal number that cannot be synchronized to the synchronization request terminal. The message is sent to the synchronization requesting mobile terminal to confirm whether to continue using the synchronization service. If the synchronization requesting mobile communication terminal wants to continue using the synchronization service, the synchronization server 30 transmits a synchronization start message to the mobile communication terminal capable of synchronization, otherwise terminates the service.

FIG. 2 is a detailed configuration diagram of the synchronization server shown in FIG. 1.

As shown, the synchronization server 30 is a message analysis unit for checking the parameters included in the synchronization attempt message as the synchronization attempt message is transmitted from the control unit 310, the interface 320, the mobile communication terminal for controlling the overall operation. In operation 330, the message analysis unit 330 transmits a synchronization preparation message to the requested mobile communication terminal to check whether synchronization is possible to the requested mobile communication terminal, and receives a response message thereto. The synchronization request unit 340 and the synchronization request unit 340 includes a synchronization initiation unit 350 for transmitting a synchronization initiation message to the requestable mobile communication terminal that can be synchronized.

Here, the synchronization initiation unit 350 checks the response message (synchronization preparation response message) for the synchronization preparation request, and if it is determined that there is a mobile communication terminal that cannot be synchronized, the synchronization is continued to the mobile communication terminal that requested the synchronization. If it is determined whether to proceed with the synchronization, the synchronization start message may be transmitted to the requested mobile communication terminal capable of synchronization, otherwise the synchronization operation may be terminated.

More specifically, the message analysis unit 330 extracts a synchronization time point, an application program identification number, a mobile communication terminal identification number number, and a mobile communication terminal identification number from the synchronization attempt message and stores them in the database 360.

In addition, the synchronization request unit 340 prepares for synchronization including a synchronization time point, an application identification number, and a synchronization request mobile communication terminal number to each mobile communication terminal with reference to the mobile communication terminal number extracted by the message analyzer 330. It generates and transmits a message, and receives a synchronization preparation response message including whether synchronization is possible from the requested mobile communication terminal.

When the synchronization initiation unit 350 transmits a synchronization preparation response message from all the requested mobile communication terminals, the synchronization initiation unit 350 checks whether synchronization is possible and synchronizes to the requested mobile communication terminal capable of synchronization. Generate and send a synchronization start message including a. If any one of the requested mobile communication terminals is found to be impossible to synchronize, the synchronization initiation unit 350 provides the mobile communication terminal information that cannot be synchronized to the synchronization requesting mobile communication terminal before transmitting the synchronization initiation message, and synchronizes. Synchronization may continue or stop according to the request of the requesting mobile communication terminal.

3 is a flowchart illustrating a mobile communication terminal synchronization method according to the present invention. In the following description, it is assumed that the first mobile communication terminal requests synchronization to the second mobile communication terminal for convenience of description.

First, as the first mobile communication terminal transmits a synchronization attempt message including a synchronization time point, an application program identification number, the number of mobile communication terminals, and a mobile communication terminal number to the synchronization server 30 (S101), the synchronization server 30. The message analyzer 330 extracts the parameters included in the synchronization attempt message and stores them in the database 360. In this embodiment, the number of mobile communication terminals is 1, and the mobile communication terminal number is an identification number of the second mobile communication terminal.

Subsequently, the synchronization requesting unit generates a synchronization preparation message including a synchronization time point, an application identification number, and a synchronization request mobile communication terminal number by using the mobile communication terminal number included in the synchronization attempt message as a receiving side. It transmits (S105).

Accordingly, the second mobile communication terminal checks whether the corresponding application program can be executed at the corresponding time point, and transmits a synchronization preparation response message indicating whether synchronization is possible to the synchronization server 30 (S107).

Upon receiving the synchronization preparation response message, the synchronization initiation unit 350 checks whether the synchronization is possible, and if so, the synchronization initiation message including the synchronization time point, the application identification number, and the synchronization request mobile communication terminal number. In operation S109, the first and second mobile communication terminals execute the corresponding application program at the corresponding time point (S111-1 and S111-3).

On the other hand, when the synchronization initiation unit 350 receiving the synchronization preparation response message confirms whether the synchronization is possible, the synchronization server reports this to the first mobile communication terminal and synchronizes at the request of the first mobile communication terminal. You can continue or stop the procedure.

In the present invention described above, for example, a program (race recording measurement program, etc.) in which several people simultaneously measure a time to measure a record is simultaneously driven in a mobile communication terminal, or the same music is output from a plurality of mobile communication terminals. It can be used for programs that show effects.

For example, when measuring the track record of a track and field athlete, the completion time should be measured by measuring the time at the starting line and then estimating the situation of the arrival point. In the case of using the synchronization system and method of the present invention, a measurement related program is downloaded to a mobile communication terminal located at a starting point and an arrival point, and the two mobile communication terminals are synchronized. After the completion time is measured by the mobile communication terminal of the destination, the accurate travel time can be measured. By doing in this way, even if the measurement of the origin and destination is not the same, it becomes possible to measure the travel time accurately.

In another embodiment, when a cheering playback program mounted in a plurality of mobile communication terminals is executed in synchronization, it is also possible to provide a service that allows multiple users to sing together using their own mobile communication terminals. It is also possible to provide an effect, which can contribute to the development of sound source-related industries.

As such, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, the above-described embodiments are to be understood as illustrative in all respects and not as restrictive. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.

Can be expected to generate revenue.

In addition, the synchronization process is not performed by a user's manipulation, but can be simply performed by only responding to a control message received from a mobile communication network, thereby maximizing convenience of use.
