[ Specifically, the game server 10 lists game data storage locations and adds, updates, or deletes new game data to storage locations corresponding to the game and user identification information, and when receiving a load request message from the terminal 20 And transmits the stored game data to the terminal 20.

The game data is data in which a game progress status of a specific user is recorded at the time when a storage event during game execution in the terminal 20 occurs. At this time, the game data may include stage information in the game, score information, item information, ranking information, and the like. However, the game data may include various information . ≪ / RTI >

The terminal 20 is a terminal capable of transmitting and receiving data using the network 30. [ The terminal 20 of the present invention may be a personal digital assistant (PDA) capable of transmitting and receiving wireless data using a network 30 including a mobile communication network, a portable multimedia player (PMP) have.

Specifically, the terminal 20 executes a game program, measures the state of the network 30 when a storage event occurs during game program execution, and stores the game data in the game server 10 or the terminal 20. [

The storage event refers to a change occurring in the game program or a change in the input signal from the user depending on the progress of the game program in order to store the game data. Specifically, it may include a periodic or non-periodic change in the game program for storing game data such as completion of each stage in the game program, completion of a given task in the game program, And may include a user's input for forcibly terminating the game program during program execution or for storing game data.

The measured value of the state of the network 30 refers to information obtained by quantitatively measuring whether or not the game server 10 and the terminal 20 are connected through the network 30 and the type and amount of traffic of the network 30. [ At this time, the network 30 status measurement value may include not only the network 30 but also a case where a problem occurs in the game server 10 or the terminal 20 and data communication can not be performed.

The terminal 20 transmits the game data to the game server 10 and stores the game data when the measured value of the state of the network 30 is better than the preset threshold value. If the measured value is not better than the threshold value, ).

In this case, the measurement value of the network 30 can be measured in units of time, speed, loss rate, etc. Specifically, when measured in a time unit, when the network 30 is in a good condition, the data transmission / Refers to a case where a data transmission / reception speed is measured in a speed unit and a data transmission / reception speed is greater than a threshold value, and the 'good' state may be different depending on a measurement unit.

2 is a configuration diagram illustrating a terminal 20 according to an embodiment of the present invention. 1 and 2, a terminal 20 according to an embodiment of the present invention includes a transmitting / receiving unit 21, an input unit 23, a storage unit 25, and a control unit 27.

The transmission / reception unit 21 has an interface for data transmission / reception with the game server 10. Specifically, the transmission / reception unit 31 has an interface for transferring game data to the game server 10 or receiving game data stored in the game server 10 during execution of the game program.

The storage unit 23 is a storage for storing game programs held by the terminal 20. At this time, the storage unit 23 may store the game data according to the state of the network 30 during game execution.

The input unit 25 provides a plurality of keys for operating the terminal 20 and generates a selection signal according to the key selection of the terminal 20 user. The input unit 25 may be a key input device such as a keypad, a pointing device such as a touch pad, or a touch screen. Specifically, the input unit 25 may receive a key input for storing game data, or may receive a key input corresponding to a selection of a storage list received from the game server 10.

The output unit 27 is a device for visually expressing game programs and data held by the terminal 20. [ The output unit 27 of the present invention includes display means such as a cathode ray tube screen, an LCD (Liquid Crystal Display), an LED (Light Emitting Diodes), an OLED (Organic Light Emitting Diodes)

The control unit 29 controls the operations of the transceiver unit 21, the input unit 23, the storage unit 25, and the output unit 27 as a whole.

The control unit 29 receives the input of the user through the input unit 23, executes the game program stored in the storage unit 25, and detects that a storage event occurs during the execution of the game program.

Specifically, the control unit 29 detects a change in the game program according to the progress of the game program or a change that occurs through the input signal from the user through the input unit 23 in order to store the game data.

The control unit 29 measures the state of the network 30 when it detects that a storage event has occurred. In this case, a method such as one way delay, delay variation, and one way packet loss may be used, but the present invention is not limited thereto.

Specifically, the control unit 29 transmits a measurement signal to the game server 10, calculates a time interval between a time point at which the measurement signal is transmitted and a point at which the measurement signal reaches the game server 10, The state can be measured. The control unit 29 transmits the measurement signal to the game server 10. When receiving the response signal for the measurement signal and the response signal for the measurement signal from the game server 10, And the state of the network 30 can be measured. In addition, if a response signal is not received from the game server 10 for a predetermined time, it can be determined that a problem has occurred in the network 30 or the game server 10, which is a connection medium with the game server 10.

At this time, when measuring the state of the network 30, a GPS (Global Positioning System) is used to perform time synchronization between the terminal 20 and the game server 10, or a time The stamp may be recorded and transmitted, but is not limited thereto.

The control unit 29 transmits the game data to the game server 10 and stores the game data when the measured value of the state of the network 30 is better than the predetermined threshold value. As described above, in the case of being better than the threshold value, the value may be large or small depending on the unit to be measured.

At this time, when the game data is transmitted to the game server 10, the controller 29 stores game identification information such as a game ID, user identification information such as a user ID, MIN (Mobile Identification Number), ESN And the identification information of the corresponding terminal 20 such as a serial number.

In addition, since there is a time interval between the time when the storage event occurs and the time when the game data is transmitted after measuring the state of the network 30, in order to store the game data at the time when the storage event occurs, In order to accurately reflect the progress of the game at the time of the storage event, the game data recorded with the time stamp may be transmitted after the time stamp is recorded in the game data at the time of the storage event.

If the measured value is not better than the threshold value, the control unit 29 does not transmit the game data to the game server 10, but stores the game data in the storage unit 25. At this time, the control unit 29 temporarily stores the game data in the storage unit 25, and if the measured value of the state of the network 30 after the storage event occurs is better than the threshold value, And the game data stored in the storage unit 25 may be deleted.

The control unit 29 may transmit a storage request message to the game server 10 when the measured value of the state of the network 30 is better than a preset threshold value. Then, when the game data storage list is received from the game server 10, the game data is output through the output unit 27.

The game data storage list is a list indicating the storage areas allocated in the game server 10 for storing a plurality of game data for each user.

The control unit 29 selects the position in the list for storing the game data through the input unit 23 and transmits the game data identification information for distinguishing the storage location of the game data and the game data to the game server 10 .

In this case, in the case of a storage event occurring periodically or aperiodically without a user input in the game program, the game data can be stored in the same storage position from the start to the end of the game program. For example, if you start a game program for the first time, you can add the game data to the first list, update the game data in the first list until the game program ends, load the game data in the second list, The game data of the second list is updated until the game program is subsequently terminated.

The control unit 29 may also store the game data identification information together with the game data in the storage unit 25 when the measured value of the state of the network 30 is not better than the preset threshold value. At this time, when the game data is stored in the storage unit 25, the control unit 29 outputs the same list as the storage list of the game server 10 through the output unit 27 and receives the user's selection through the input unit 23 It is desirable to store game data.

Meanwhile, the control unit 29 may execute a game program and transmit the game data load request message to the game server 10 in response to a user's input through the game menu window or the game in progress input unit 23. The control unit 29 receives the game data storage list from the game server 10, and outputs the game data storage list through the output unit 27. Next, the game data identification information to be loaded by the user is transmitted through the input unit 23, and when the game data corresponding to the game data identification information is received from the game server 10, the game program is advanced using the received game data .

Thus, by storing the game data in the game server 10, the game server 10, when receiving the download request of the game program from the terminal 20, obtains the identification information of the game program, the identification information of the terminal, It is possible to check whether there is game data stored in the same game program previously stored in the same game program and to transmit the game data stored together with the game program if there is the stored game data. Even if the user re- There is an advantage that one game data can be used again.

3 is a flowchart illustrating a method of storing game data according to a network status according to an embodiment of the present invention. 1 and 3, the terminal 20 executes a game program stored therein (S41)

In step S41, the terminal 20 that is executing the game program detects that a storage event, which is a change occurring in the game program or a change that occurs through a signal input from the user through the input device, is generated according to the progress of the game program (S43).

At this time, the terminal 20, which is sensed by the occurrence of the storage event, can record the time stamp on the game data at the time when the storage event occurs.

In step S43, the terminal 20 senses that the storage event has occurred, and then measures the state of the network 30 (S45). At this time, the terminal 20 can use a method such as one way delay, delay variation, and one way packet loss, but the present invention is not limited thereto .

The terminal 20 measuring the state of the network in step S45 confirms whether the measured value of the network state is better than the threshold value (S47). At this time, the terminal 20 compares the measured value of the network state with the threshold value, and may be larger or smaller than the threshold depending on the unit of measuring the network state.

The terminal 20 compares the measured value of the network state with the threshold value in step S47 and transmits the game data to the game server 10 in step S49 upon confirming that the network state is good.

At this time, when transmitting the game data to the game server 10, the terminal 20 transmits game identification information such as game ID, user identification information such as a user ID, MIN (Mobile Identification Number), ESN And the identification information of the corresponding terminal 20 such as a serial number.

In addition, when the time stamp is recorded in the game data at the time of the storage event, the game data in which the time stamp is recorded may be transmitted to the game server 10.

In step S47, the terminal 20 comparing the measured value of the network state with the threshold value stores the game data therein (S51), if it is confirmed that the network state is not good.

At this time, the terminal 20 temporarily stores the game data therein, and then stores the game data in the game server 10 when the measured value of the state of the network 30 is greater than the threshold value And store game data stored therein.

4 is a flowchart illustrating a method of storing game data according to a network status according to another embodiment of the present invention. The steps S61 to S67 are the same as the steps S41 to S47 in FIG. 3, and the description thereof will be omitted.

In step S67, when comparing the measured value of the network state with the threshold value, the terminal 20 transmits a storage request message to the game server 10 (S69).

In step S69, the terminal 20 that has transmitted the storage request message receives the game data storage list from the game server 10 and outputs the received game data storage list in step S71.

In step S71, the terminal 20 that has output the game data storage list selects the position in the list for storing the game data by the user through the input device and receives the game data identification And transmits the information to the game server 10 (S73).

The terminal 20, which compares the measured value of the network state with the threshold value in step S67, stores the game data identification information together with the game data therein, if it is confirmed that the network state is not good (S75 ). At this time, when storing the game data in the terminal 20, it is preferable that the terminal 20 outputs the same list as the storage list of the game server 10 and stores the game data according to the user's selection through the input device.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be appreciated by those skilled in the art that numerous changes and modifications can be made to the invention. Accordingly, all such appropriate modifications and variations, and equivalents thereof, should be regarded as within the scope of the present invention

According to the present invention, there is no need for a separate device to store game data in a game server, thereby minimizing the additional cost. Particularly, in view of the tendency that a large number of users enjoy a game through a mobile terminal, the method of transmitting game data according to the network status of the present invention will not be utilized much.
