1 is an exemplary view showing a communication mechanism between a mobile communication terminal and a USIM card according to the prior art.

The USIM card 100 is a card capable of storing and calculating data and information used in a WCDMA terminal. The USIM card incorporates a microprocessor (MPU), memory, card operating system (COS), security algorithms, and EEPROM (Electronically Erasable Programmable Read Only Memory). COB (Chip On Board) type card with function.

The USIM card 100 includes ID, location information, encryption key, data service variable value, user identification number (IMSI: International Mobile Subscriber Identity), function and environment variable value, service network information, service table, Various information such as subscriber authentication key, PIN, call time and fee information may be stored.

The USIM card 100 may be mounted on the mobile communication terminal 150 to transmit and receive information stored in the mobile communication terminal 150 and the USIM card, and the USIM card 100 may be separated from the mobile communication terminal 150. It is possible. Therefore, when using the other mobile communication terminal by inserting the USIM card 100 into another mobile communication terminal, the information stored in the USIM card 100 can be used in other mobile communication terminals.

In particular, due to recent developments in technology, the USIM card 100 having a large memory has been developed to store more data in the USIM card 100. For example, map information may be stored.

As shown in Fig. 1, the communication between the mobile communication terminal 150 and the USIM card 100 according to the prior art is a half duplex mode in the form of request / response using a syntax defined in the ISO 7816 standard. Follow the communication method. In general, the transmission scheme defined in the ISO 7816 standard supports low-speed data communication, eg, 9.6 kbps, using serial bidirectional transmission lines.

The ISO 7816 standard provides two transport protocols.

One of them, the T = 0 protocol, is a transmission protocol used in the early days of ISO 7816 and follows the asynchronous half-duplex byte transmission scheme.

The remaining T = 1 protocols are called block transfer protocols, and there is room for some improvement in security compared to byte transfer protocols. Since adopting T = 0 protocol in GSM's 11.11 Subscriber Identification Module (SIM), next-generation credit card EMVs have adopted both T = 0 and T = 1 protocols.

Referring to FIG. 1, a command is initiated by the mobile communication terminal 150, and a card operating system (Card OS) embedded in the USIM card 100 interprets a command received from the mobile communication terminal 150. Thus, the state of the data stored in the USIM card 100 is updated, and a response to the received command is transmitted to the mobile communication terminal 150.

ISO 7816-7 provides a command message and a response message transmitted and received between the mobile communication terminal 150 and the USIM card 100 using a conventional application protocol data unit (APDU). However, the syntax currently provided through the APDU is limited, and there is a disadvantage in that a plurality of request / response procedures must be performed to obtain information stored in a specific element file.

Therefore, in order to acquire the information stored in the specific element file on the USIM card 100 in the mobile communication terminal 150, the mobile communication terminal 150 requires a stepwise connection from the master file to the corresponding element file.

In addition, even if the mobile communication terminal 150 accesses a specific element file, processing in units of records is performed, so that a large amount of processing time may be required to acquire all the information stored in the specific element file.

 Hereinafter, a method of providing partial map information in the mobile communication terminal 150 using the USIM card 100 storing the browser area map information will be described in detail.

Figure 2 is a block diagram showing the internal configuration of a USIM card according to an embodiment of the present invention.

As shown in FIG. 2, the USIM card 100 according to the present invention includes a USIM interface 210, an SQL parser 220, a map storage 230, a peripheral information storage 250, and a mapping table ( mapping table 240, a card operating system (COS), a USIM controller 260, a read only memory (ROM), a random access memory (RAM), and the like.

The USIM interface unit 210 is a means for exchanging various information with the mobile communication terminal 150. In particular, in the present invention, the USIM interface unit 210 receives the location information and map providing request message of the mobile communication terminal 150 from the mobile communication terminal 150. Then, the read partial map information is transmitted to the mobile communication terminal 150.

Since the USIM card 100 should be available to all mobile communication terminals capable of mounting the USIM card 100, that is, the USIM card 100 has compatibility, the configuration of the USIM interface unit 210 is as defined in the standard and the standard is known to those skilled in the art. Self-explanatory

The USIM card 100 according to the present invention may identify whether the type of the request message received from the mobile communication terminal 150 is a general SQL syntax or an APDU message defined in ISO 7818. Here, the type identification of the request message is preferably performed by the card operating system (COS).

If the received request message is an SQL syntax, the USIM card 100 generates a series of APDU command messages by itself in the pre-stored SQL parser 220 and displays a result of processing the APDU command message in a predetermined temporary recording area. For example, in RAM. Here, the SQL parser 220 may perform a function of decoding a SQL syntax according to a control signal of a card operating system (COS) to generate a series of APDU command messages, and storing the processing result in a temporary recording area. .

When the SQL parser 480 executes all APDU command messages corresponding to the decrypted SQL syntax, the SQL parser 480 transmits the processing result to the mobile communication terminal 150 through the USIM interface 450.

According to another embodiment of the present invention, the SQL parser 480 provides at least one sequential ADPU command message corresponding to the requested SQL syntax to the card operating system (COS), and the card operating system (COS). Note that) may use the APDU command message to perform file selection and record extraction. At this time, when there is a processing result to be transmitted to the mobile communication terminal 150, the card operating system (COS) transmits the processing result to the mobile communication terminal 150 through the USIM interface 450.

The map storage unit 230 stores local map information.

In the present specification, the local map information is map information that can represent the widest range including partial map information corresponding to the location information of the mobile communication terminal 150. For example, the map information of South Korea, Asian map information, and the world map Refers to a map set by the user, such as map information.

That is, it means an original map capable of reading partial map information corresponding to the location information of the mobile communication terminal 150.

For example, for convenience of explanation and understanding, it is assumed that the local map information is the entire map of South Korea, and the mobile communication terminal 150 is currently located in Gangnam station.

When the mobile communication terminal 150 receives the current location information (Gangnam station) and delivers it to the USIM card 100, the USIM card 100 will read the map information near the Gangnam station of Seoul from the entire map of Korea and deliver it to the mobile communication terminal. , Where the map information near the Gangnam station is partial map information.

The local map information is stored in the map storage unit 230 and can be downloaded or updated periodically or at a user's request. For example, even if the local map information stored in the map storage unit 230 is Korea map information, if the European map information is downloaded by the user's needs, the European map information may be newly stored in the map storage unit 230. have.

According to the present invention, the map storage unit 230 is configured as an image file rather than text, so that the size of the data is larger and the partial map information corresponding to the location information among the local map information can be read more easily. It is preferable to construct.

When the map storage unit 230 is implemented as a database, the USIM control unit 260 may include a database management system (DBMS) for managing a database. DMBS performs access control and management functions for the database. For example, the DBMS can read the partial map information stored in the database directly through the address of the database where the partial map information corresponding to the location information is stored, and can efficiently manage the local map information in the future. You can do that.

The mapping table 240 may read the partial map information corresponding to the selected point by selecting a point corresponding to the location information received from the mobile communication terminal 150.

The mapping table 240 may determine which of the partial map information corresponding to the location information received from the mobile communication terminal 150 among the local map information stored in the map storage unit 230 is controlled by the USIM controller 260. Can be. That is, it may be determined whether the location of the mobile communication terminal 150 is located in the area map information.

In addition, the mapping table 240 may inform the address of the map storage unit 230 in which partial map information corresponding to the location information is stored. In particular, when the map storage unit 230 is implemented as a database, when the partial map information is returned, the DBMS controls the DBMS to read the partial map information stored at the corresponding address, thereby making it easier to read the partial map information. There is this.

The configuration and implementation method of the mapping table 240 will be described in more detail with reference to FIG. 9.

The surrounding information storage unit 250 stores the surrounding information.

The surrounding information not only provides a map to the user, but also informs information such as major buildings, shops, and historical sites around the provided map, and thus, the user can effectively use the map.

For example, when the surrounding information includes restaurant information, the user may obtain information about a restaurant located nearby, so that the user may easily use a nearby restaurant even if the user goes to an unfamiliar place.

In addition, when the phone number is included in the surrounding information, the voice call may be connected to the terminal corresponding to the phone number displayed on the map provided to the user. To this end, when there is a selection of the corresponding phone number from the user, the mobile communication terminal 150 may receive the corresponding phone number information from the USIM card 100 and attempt to connect a voice call to the terminal corresponding to the corresponding phone number.

As an example of a method of providing the surrounding information together with the partial map information, the surrounding information may be included in the partial map information.

That is, since the map information itself stored in the map storage unit 230 includes surrounding information, when the partial map information corresponding to the location information received from the mobile communication terminal 150 is read, the surrounding information is also read and provided together. Can be.

In this case, it is obvious that the surrounding information is not stored in the surrounding information storage unit 250.

In another embodiment, the peripheral information is stored in the peripheral information storage unit 250 separate from the map storage unit 230 in which the map information is stored, and the peripheral information corresponding to the read partial map information is received from the peripheral information storage unit 250. You can read it.

That is, the peripheral information corresponding to the location information received from the mobile communication terminal 150 may be read out from the peripheral information storage unit 250 and provided together with the partial map information which has already been read.

The method of reading the surrounding information can be easily changed and implemented in various ways. Preferably, a point corresponding to the location information received from the mobile communication terminal 150 is selected to surround the surrounding information corresponding to the selected point. After reading from the information storage unit 250, the peripheral information read in the partial map information read by the control of the USIM controller 260 may be overlapped and transmitted to the mobile communication terminal 150.

The method of reading the surrounding information corresponding to the location information may use a mapping table or may be performed using the coordinate values of the received location information. The method of reading the surrounding information corresponding to the location information can be easily changed.

Particularly, when the map storage unit 230 and the surrounding information storage unit 250 are implemented in the form of a database, the map storage unit 230 and the surrounding information storage unit 250 may be connected and stored between the partial map information and the surrounding information of the region, and the map storage unit 230 may be controlled by the DBMS. And the peripheral information storage unit 250 may be managed.

The USIM control unit 260 may be configured to each component included in the USIM card 100 (eg, the USIM interface unit 210, the SQL parser 220, the map storage unit 230, and the peripheral information storage unit 250). ), And generates and outputs a control signal for controlling the mapping table (240).

The USIM control unit 260 may control the USIM interface unit 210 to receive location information of the mobile communication terminal from the mobile communication terminal 150, and transmit the read partial map information to the mobile communication terminal 150. The interface unit 210 may be controlled.

The location information of the mobile communication terminal may be generated in various ways. For example, in the case of a mobile communication terminal 150 equipped with a GPS device, the mobile communication terminal 150 may generate location information in a coordinate format by using information received from a GPS satellite. Location information may be generated using a triangulation method. The location information generating method can be easily changed by various methods by those skilled in the art of communication.

In addition, the USIM controller 220 may control the SQL parser 220 to be executed when the map providing request message received from the mobile communication terminal 150 is an SQL syntax.

In addition, the USIM controller 220 may control to read the partial map information stored in the map storage unit 230 using the location information received from the mobile communication terminal 150. As described above, the USIM controller 220 reads the partial map information. Mapping table 240 may be used to ship.

The method of reading the partial map information by the USIM controller 260 can be easily changed in various ways.

According to an embodiment, after selecting a point corresponding to the location information, it is determined whether the selected point is located within a region preset in the area map information stored in the map storage unit 230, and thus the area including the selected point is partially included. This is a method of reading out map information.

For this purpose, the local map information should be divided into regions of a predetermined size and stored in the map storage unit 230.

The USIM controller 260 may consider an area including a point corresponding to the location information as partial map information and read out the corresponding area.

This will be described in detail with reference to FIG. 8A.

In another embodiment, after selecting a point corresponding to the location information, a method of reading a partial radius as partial map information about the selected point.

The USIM controller 260 may control to cut a map having a predetermined radius from the selected point of the local map information stored in the map storage 230 and to read the partial map information.

The method of setting the size of the radius can be variously changed according to factors such as the scale of the map or the size of the display unit of the mobile communication terminal 150.

This will be described in detail with reference to FIG. 8B.

In addition, a ROM is a read-only storage location for storing a program, and a program to be loaded into a card operating system and a basic API may be stored.

RAM is a volatile memory used as an auxiliary storage device in a microprocessor of a completed USIM card, and is a recording device for temporarily storing variables and data generated during program execution.

As such, when storing the local map information in the USIM card 100, the time required for the user to view the desired map information because the user does not have to access the map providing server in order to use the map providing service. There is an advantage that can be reduced, and there is an advantage that can reduce the cost burden due to data communication.

In more detail, FIG. 3 is a diagram for describing a procedure of acquiring map information stored in the USIM card 100 by the mobile communication terminal 150 using SQL syntax.

Referring to FIG. 3, when the USIM card 100 is mounted in the mobile communication terminal 150 and power is supplied, the mobile communication terminal 150 transmits a reset signal to the USIM card 100 (step S310). )do.

When the internal reset procedure is completed, the USIM card 100 transmits an answer to reset (ATR) signal to the mobile communication terminal 150 (step S320).

Thereafter, when the mobile terminal 150 transmits the SQL syntax to the USIM card 100 in step S330, the USIM card 100 transmits the received SQL syntax to the card operating system (COS).

The card operating system (COS) transmits a parsing request signal including the received SQL syntax to the SQL parser 220 (step S340), and the SQL parser 220 performs the received SQL parsing (step S350). )do.

Afterwards, in step S360, the SQL parser 220 generates a parsing result response signal including a parsing result for the corresponding SQL syntax, where the parsing result includes a list of APDU commands to be sequentially performed. Send to (COS).

The card operating system (COS) reads the partial map information stored in the map storage unit 230 using the received syntax decoding result (step S370), and then transfers the read partial map information to the mobile communication terminal 150 ( Step S380).

4 is a flowchart illustrating a process of processing partial map information in a USIM card according to an embodiment of the present invention.

The mobile communication terminal 150 transmits a map information provision request message to the USIM card to obtain partial map information stored in the USIM card 100 (step S410).

The USIM controller 260 transmits the location information of the mobile communication terminal 150 included in the received request message to the mapping table 240 (step S420).

The mapping table 240 reads the partial map information corresponding to the received location information, and acquires the address of the map storage unit 230 in which the partial map information corresponding to the location information is stored (step S430). Obtaining the address of the map storage unit 230 in which the partial map information is stored is to more easily read the partial map information in the map storage unit 230, and the map storage unit 230 may be implemented as a database. Do.

Subsequently, a request is made to read the mapped partial map information (data) (step S440) and the partial map information is read from the map storage unit 230 (step S450) under the control of the USIM controller 260 to read the read partial map information. Transfer to mobile communication terminal 150.

The partial map information may be provided with the surrounding information, and the surrounding information may be separately read along with the partial map information and provided with the partial map information, as described above.

5 is a block diagram showing the configuration of information included in the surrounding information according to an embodiment of the present invention.

The surrounding information refers to information such as major buildings, restaurants and historic sites located near the partial map information read from the large capacity USIM card 100 and delivered to the mobile communication terminal 150. You can provide it with information.

When the neighboring information according to an embodiment of the present invention is included in the partial map information, the neighboring information is provided by providing the partial map information so that the neighboring information does not need to be stored separately. Only the case where it is stored separately from the partial map information will be described.

For example, the surrounding information may be stored in the surrounding information storage unit 250 including at least one of an industry category 510, an object location 520, a business name 530, and phone number information 510.

Business type classification 510 indicates the type of business of the object, and means, for example, a restaurant, a hospital, a department store, a hypermarket, or the like. The industry classification 510 may be stored in the form of text, but it is preferable that the industry classification 510 is stored in the form of an icon in order to provide it with a map.

The object location 520 indicates location information of the object, and may be stored in a 1: 1 match with the partial map information. The object location 520 may be stored as coordinate information so as to correspond to the partial map information, and if the coordinate information exists in the read partial map information, it may be displayed on the partial map information.

The trade name 530 indicates the name of the trade name of the object and is preferably stored in the form of text.

The phone number information 540 indicates a phone number of the corresponding object, and is preferably stored in the form of a number.

The phone number information 540 may be connected to the voice call connection unit of the mobile communication terminal 150 under the control of the USIM control unit 260 in order to make a call to the corresponding object directly on the screen on which the map is displayed.

As such, when the map providing service is provided together with the surrounding information, the user can easily grasp the surrounding information even in an unfamiliar place, and there is an advantage that the user can make a call to the corresponding object even without using the telephone number guide.

Although not shown in FIG. 5, in another embodiment, tourism information that can be enjoyed by a user located in partial map information may be provided. The tourist information may include, for example, a tasting course, a tour course, a fishing course, and the like, and the tourist information that can be enjoyed by the user can be changed in various ways.

6 and 7 are exemplary views showing an example of a map provided according to an embodiment of the present invention.

FIG. 6 illustrates partial map information generated by the USIM card 100 by using the location information of the mobile communication terminal 150, and illustrates only a simple map, and FIG. 7 illustrates neighboring information of the partial map information.

For example, for convenience of explanation and understanding, it is assumed that the mobile communication terminal 150 is currently located in Gangnam Station.

The mobile communication terminal 150 generates current location information (Gangnam Station) and transfers the current location information to the USIM card 100. The USIM card 100 reads the partial map information corresponding to the received location information and transmits the partial map information to the mobile communication terminal 150 again.

When providing only the map around the Gangnam station as shown in FIG. 6, the user cannot view the information of the corresponding area, and thus, it is preferable to provide partial map information including the surrounding information as shown in FIG. 7.

The surrounding information may display the building name, subway station exit information, road name, etc., and may be provided in the form of text or emoticon. The method of providing the surrounding information may be easily changed in various ways.

FIG. 8B illustrates another embodiment of a method of reading partial map information. After selecting a point corresponding to the location information, FIG. 8B illustrates a method of reading a partial radius of the partial map information as partial map information.

That is, a map having a predetermined radius may be cut out based on the selected point of the local map information stored in the map storage unit 230 and read out as partial map information.

In order to explain the difference between FIG. 8A and FIG. 8B, a case in which the mobile communication terminal 150 is located at a point A and a point B will be described as an example.

When the area including the location information is read as the partial map information as shown in FIG. 8A, since the A and B points are both located in the same area, the partial map information to be read is the same, and thus the provided partial map information is the same.

However, when a predetermined radius is read as partial map information based on the location information as shown in FIG. 8B, the partial map information to be read is different and thus the provided partial map information is different.

In addition to FIGS. 8A and 8B, the method of reading the partial map information stored in the map storage unit 230 may be easily changed in various ways.

9 is a diagram illustrating a typical example of the mapping table 240 stored in the USIM card 100.

The mapping table 240 is a type of filter for reading the partial map information stored in the map storage unit 230 using the location information received from the mobile communication terminal 150. The mapping table 240 includes the location information and the partial map information. A table stored by matching: 1.

For convenience of explanation and explanation, for example, it is assumed that the location information received from the mobile communication terminal 150 is 'A'.

The partial map information corresponding to the location information 'A' may be 'a' and 'a' may include address information of a location where the corresponding partial map information is stored. In this case, the partial map information stored at the address may be read by the control of the USIM controller 260.

In FIG. 9, the mapping table is configured in the form of a two-dimensional array, but the method of implementing the mapping table can be easily changed in various ways.

For example, when the location information is implemented in coordinates of the form (x, y), the mapping table may be implemented in a three-dimensional array to read the corresponding partial map information.

Alternatively, when the mapping table is implemented in the form of a database, the location information may be a query to read partial map information corresponding to the query.

Since a large capacity USIM card 100 has been developed, a large capacity mapping table 240 can be stored in the USIM card 100, and when the partial map information is read using the mapping table 240, the partial map information is easier to use. It can be read easily.
