The present invention relates to a method for transmitting location information of a calling terminal to a receiving terminal, and more particularly, sets a menu for selecting location information transmission of a calling terminal on a message editing screen, and when a caller presses the selection menu, a service server. The present invention relates to a method of transmitting location information of a calling terminal to a receiving terminal in an MMS message format.

With the development of terminal manufacturing technology and communication technology, mobile terminals of recent years have become a kind of multimedia device that meets various needs and preferences of individuals beyond simple communication means.

In particular, as competition in attracting subscribers among mobile operators intensifies, various services have been attempted. As a result, mobile terminals provide message transmission / reception services such as SMS and MMS, wireless Internet services, and location-based services (LBS). .

Among them, the LBS service is a service applied to areas such as traffic information, friend search, and emergency rescue based on the location of the mobile terminal. In this case, the positioning may be performed by a GPS method or a cell method in a separate positioning server, or may be roughly performed by using the cell ID or sector ID of the mobile terminal stored in the home location register (HLR).

On the other hand, in recent years, the LBS service has been proposed to request that the calling terminal transmits its location information to the receiving terminal after accessing the predetermined location information providing server.

By the way, whether to obtain the other party's location information or to provide the other party's location information to the other party, in order to use the current service, a predetermined service server for providing the location information through the WAP (Wireless Application Protocol) Must be connected to

Therefore, the user is unfamiliar with the use of the wireless Internet, the operation is inconvenient, the use time is long, which causes a problem that the burden of data call charges increase. This problem acts as a factor to lower the utilization rate of the location information service.

The present invention has been made to solve this problem, and an object thereof is to enable a sender to easily and inexpensively transmit his or her location information to a receiver. In addition, the purpose of this is to improve the utilization rate of location information providing service.

In order to achieve the above object, the present invention provides a method comprising: a first step of inputting a number of a receiving terminal through a short message editing screen in a calling terminal and requesting providing location information of the calling terminal; A second step in which the request signal is transmitted to a service server providing location information through a short message service (SMS) route; A third step of obtaining location information of the calling terminal from the service server and creating a location information file; And a fourth step of transmitting, by the service server, the location information file to the receiving terminal through a multimedia message service (MMS) route.

In the first step, the short message editing screen is provided with a selection menu for requesting caller location information, and the location information providing request may be made by a caller pressing the selection menu.

The second step is to generate a service code to identify that the location information is requested from the calling terminal, and transmits the message data including the receiving terminal number and the service code to a short message service center (SMSC) step; Only when the service code is included in the message data, the SMSC may include transmitting a message and telephone number information input by the caller to the service server.

In addition, the second step, generating a service code that can identify that the location information is requested from the calling terminal, and transmits the message data including the receiving terminal number and the service code to a short message service center (SMSC) step; The SMSC transmits the message data to a separate confirmation module capable of confirming the service code, and transmits the message and telephone number information input by the sender to the service server only when the service code is included. It may include the step.

In the third step, the service server may perform an authentication procedure for using the service of the calling terminal.

Hereinafter, with reference to the drawings will be described in detail a preferred embodiment of the present invention.

Location information providing service system according to an embodiment of the present invention, as shown in the configuration of Figure 1, the calling terminal 11, the receiving terminal 12, between the calling terminal 11 and the receiving terminal 12 A mobile communication network 20 for relaying mobile communication, a short message service center (SMSC) 30 interworking with the mobile communication network 20, and a service for generating location information files by obtaining location information of a calling terminal Server 40, Multimedia Messaging Service Center (MMSC) (50) for transmitting the location information file to the receiving terminal 12 in accordance with the MMS message standard, etc.,

The originating terminal 11 or the receiving terminal 12 includes not only cellular phones and PCS phones but also electronic devices such as PDAs having mobile communication functions, and should have a function of transmitting and receiving short messages or multimedia messages.

In particular, the calling terminal 11 should be equipped with an application supporting the caller location information providing service in conjunction with the SMS message according to an embodiment of the present invention, for example, in the short message (SMS) edit screen in the embodiment of the present invention. Provide the 'Send my location' menu.

Therefore, when the caller enters the message and the telephone number of the receiving terminal 12, and presses the 'send my location' menu, the mobile communication network generates a predetermined service code as well as the input message, receiving and calling terminal number. 20) to the SMSC 30.

The service code is added to identify whether the SMS message transmitted from the calling terminal 11 is a target of the location information providing service.

The mobile communication network 20 is a base station transmitter (BTS) connected to a receiving or calling terminal (11, 12) through a wireless channel, the radio channel allocation and release for the terminals (11, 12), terminals (11, 12) And base station controller (BSC) that performs functions such as transmission output control of base station transmitter and handoff decision between cells, subscriber / receive call processing, handoff procedure processing, interworking with other networks. Performing mobile switching center (MSC);

The SMSC 30 serves to relay the short message transmitted by the sender inputted from the calling terminal 11 to the receiving terminal 12 according to the SMS transmission standard, and particularly from the calling terminal 11 in the embodiment of the present invention. The SMSC 30 has a service code checking means for checking whether the transmitted message is a location information providing service.

The service code confirmation means may be included in the SMSC 30 as described above, but may be installed in the form of a confirmation module at the rear end of the SMSC 30, in which case the confirmation module is a kind of gateway to perform a routing function. It can also be

Regardless of how it is installed, the short message without the service code is sent to the mobile switching center on the receiving terminal 12 side just like a normal SMS, and the short message with the service code provides the location information providing service. It is transmitted to the service server 40.

The service server 40 obtains the location information of the calling terminal 11 using the message and the related information transmitted via the SMSC 30, and the location information to be transmitted to the receiving terminal 12 based on the obtained location information. Create a file.

In addition, the MMS message attaching the generated location information file to the message input from the calling terminal 11 is transmitted to the MMSC (50).

The location information of the calling terminal 11 may be obtained from a separate positioning entity (PDE) for positioning the location of the calling terminal 11 in a GPS method or a cell method.

The GPS method can calculate the position of the calling terminal 11 very accurately, but it cannot be used when the calling terminal 11 is not equipped with a GPS receiver, so the error range is somewhat lower than the GPS method unless it is particularly necessary. Large cell positioning is also possible.

On the other hand, although the base station ID or sector ID information stored in the home location register is too schematic information, for example, it may be utilized in a special case of providing rough location information free of charge.

The MMSC 50 attaches the location information file received from the service server 40 to the message input by the sender and transmits the location information file to the receiving terminal 12 according to the MMS transmission standard.

Hereinafter, a process of providing location information according to an exemplary embodiment of the present invention will be described with reference to the signal flow diagram of FIG. 2 and FIG. 1.

First, the user of the calling terminal 11 needs to subscribe to the location information providing service according to an embodiment of the present invention and set a necessary application through a predetermined procedure.

When the basic setting is completed, when the caller opens the message editing screen in the calling terminal 11, the message editing screen as shown in FIG. 3 is displayed.

The message edit screen of the present invention includes, for example, a "send my location" or a "not send" menu, and is basically set to "not send". (ST11)

Therefore, when the user enters the required message and selects the "Send my location" menu, a screen for inputting the telephone number of the receiving terminal 12 is displayed, and after entering the telephone number of the receiving terminal in this screen, pressing the OK button The input message, the telephone number of the receiving terminal, and the telephone number of the calling terminal are transmitted to the SMSC 30.

In this case, it is preferable to set the location information providing service according to an embodiment of the present invention even if the menu "Send My Location" is immediately selected without inputting the message content.

The telephone number of the receiving terminal 12 may be input in advance before displaying the message editing screen.

On the other hand, when the "send my location" menu is selected in the calling terminal 11, the calling terminal 11 transmits a predetermined service code to the message data to be sent to the SMSC (30). (ST12, ST13)

The SMSC 30 checks whether a predetermined service code is included in the message data received from the calling terminal 11 by using the service code checking means, and if not, receives the received message in the same manner as a normal SMS. Transfer to the terminal 12.

If the service code is included, the received data is transmitted to the service server 40, and the data transmitted to the service server 40 includes an input message, a telephone number of a receiving terminal, a telephone number of a calling terminal, and the like. . (ST14, ST15)

The service server 40 obtains the location information of the calling terminal 11 from a predetermined positioning entity (PDE) using the calling terminal's telephone number, and uses the obtained location information and the map DB (not shown). Create an information file.

In addition, the service server 40 may perform an authentication procedure for whether the caller is a service subscriber of the present invention or whether the service is available. (ST16)

Subsequently, the service server 40 transmits the message inputted by the sender, the generated location information file, the telephone number of the receiving terminal, etc. to the MMSC 50 to the receiving terminal 12 to which the location information file is attached. Request to send. (ST17)

The MMSC 50 generates an MMS message using the location information file and the message inputted by the sender, and then stores the MMS message in an MMS mail server (not shown) and then informs the receipt of the MMS message (MMS-). NOTI) is transmitted to the receiving terminal 12.

After receiving the notification message, the receiving terminal 12 accesses the MMSC 50 and receives the MMS message as shown in FIG. 4. (ST18)

According to the present invention, since the caller only needs to select the location information providing menu on the message editing screen of the calling terminal without the complicated process of accessing the wireless Internet, the location information providing service can be used quickly and simply.

Therefore, it is expected that the utilization rate of location information providing service will be greatly improved due to such convenience of use.
