The present invention relates to a method for providing location information of a mobile terminal, and more particularly, in a location information providing system for providing location information of a mobile terminal, requesting location information based on a specific region of the mobile terminal. A method for providing location information of a mobile terminal that can be provided to a location service user.

Generally, a system for providing location information of a mobile terminal (hereinafter referred to as "terminal") is composed of a user who uses a location related service (hereinafter referred to as "location service user"), a location service provider, and a target terminal. Here, the location service user is a communication device such as a terminal of a user requesting location information (longitude and latitude) of the target terminal. Location service user {SUPL (Secure User Plane Location) AGENT} provides a location service provider (SLP: SUPL (Secure User Plane Location) Location) to provide location information of a target terminal with a predetermined period for a specific time. Request to Provider}.

The location service provider requests the target terminal to provide location related information for obtaining location information at the request of a location service user, and obtains location information of the target terminal with the location related information provided from the target terminal. Send to the user.

The conventional method for providing location information of a mobile terminal provides location information of the mobile terminal to the location service user at a predetermined time period from the location service start time to the end time set by the location service user. That is, the conventional method of providing location information of a terminal device has a certain time period within a specific time and repeatedly provides location related information about the terminal to a location service user.

However, the conventional method of providing location information has a problem in that the location service user cannot be provided with information on a specific area where the target terminal is located. In addition, the conventional method for providing location information of the mobile terminal does not provide the movement type of the target terminal even if the specific area where the target terminal is located changes, so the location service user cannot receive the movement type information of the target terminal. There is a problem.

For example, if a parent wants to check the school attendance of a child with a terminal, whether the child has arrived in a specific area of school (learning state) or outside the school (leaving state) or in school If you want to know the (within state), there is a problem that can not provide this service by the conventional method of providing location information of the mobile terminal.

In order to solve the above problems, the present invention is to provide a method for providing location information of a mobile terminal capable of providing a location service user with a type of movement to a specific region for a target terminal.

In addition, the present invention is to provide a method for providing location information of a mobile terminal capable of providing a location service user with a location and type of location change of a target terminal based on a specific region, such as entering or exiting a specific region.

The above object is achieved according to the embodiment of the present invention as follows.

In the present invention, the location service provider measures the location of the target terminal while recognizing a specific area desired by the location service user. At this time, if the location service provider and the target terminal acquire the location information of the target terminal while periodically exchanging messages for location measurement, the location service provider corresponds to the location corresponding to the acquired location information of the target terminal and the specific request requested by the location service user. The target area is changed to determine the change type of the target terminal by comparing the target area. That is, the location service provider determines whether the target terminal enters a specific region, a leaving state, or a within state.

If it is determined that the location change for the specific area requested by the location service user has occurred, the location service provider reports the location and location change type information of the current target terminal acquired to the location service user only when the location change occurs. However, if the location service user requests repetitive reporting at a time interval, the location service provider may report the location of the target terminal to the location service user at that time even if the location change does not occur.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

1 is a flowchart illustrating a preferred embodiment of a method for providing location information of a mobile terminal for a specific area according to the present invention. Here, the location information includes information on a location change type indicating a type of movement of the mobile terminal based on a location where the mobile terminal currently exists and a specific region.

According to the present embodiment, a system for providing location information of a mobile terminal includes a location service user 100 requesting location information of the target terminal 300 and location information of the target terminal 300 to the location service user 100. It provides a location service provider 200, and the target terminal 300 for transmitting the information for location measurement to the location service provider 200.

First, the location service user 100 provides the location service provider 200 with information on whether the target terminal 300 enters (Entering state), leaving (state), or within state for a specific region (hereinafter, It transmits the location service request message of the target terminal 300 requesting to provide "location change type information" (S110). The location service user 100 requests the location service provider 200 for location change type information of the target terminal 300 in a specific region by using a triggered location reporting request (TLRR) message of a mobile location protocol (MLP).

2 is a diagram illustrating a triggered location reporting request (TLRR) message format of a mobile location protocol (MLP) used in the present embodiment.

As shown, the TLRR message of the MLP, the unique ID information {MS (Mobile station) -ID} 410 of the target terminal, location information request authentication information (LCS-client) 420, service start time information (start) time (430), service stop time information (stop time) (440), service delivery interval (450), specific area information (460), change area type (change area type) information (470), And a location request flag 480.

The unique ID information (MS-ID) 410 of the target terminal is a unique ID of the target terminal 300. The location information request authentication information (LCS-client) 420 is information required for authorization and authentication (Authentication / Authorization) of the location information service of the target terminal 300 requested by the location service user 100.

The service start time information (start time) 430 indicates a start time of a service that is requested to provide location information of the target terminal 300 requested by the location service user 100. Service stop time information (stop time) 440 indicates the end time of the service requested to provide the location information of the target terminal 300 requested by the location service user 100. The service providing interval information 450 is the location of the target terminal 300 requested by the location service user 100 from the service start time to the end time by the service start time information 430 and the service end time information 440. Indicates the cycle of the service that requested to provide the information. The location service user 100 may not transmit the service start time information 430 and the service end time information 440. In this case, the location service provider 200 may provide the location service user 100 with the location information of the target terminal 300 according to the service providing period information 450 immediately after receiving the location service request message.

In addition, the service start time information 430, the service end time information 440, and the service providing period information 450 may have two types.

That is, the information 430, 440, 450 may be service time information related to the location service user 100 and the location service provider 200, or may be service time information related to the location service provider 200 and the target terminal 300. have. In addition, the location service user 100 may set and transmit both types of time information, or use the service time information preset in the location service provider 200.

The specific area information (target_area) 460 is information indicating an area designated by the location service user 100 to request location and location change type information.

The change-area-type information 470 may include information about a location change type (entering, leaving, or entering a specific region based on a specific region) of the target terminal 300 for which the location service user requires reporting. Information indicating at least one of existence (Within).

The location request flags loc-estimates 480 select not only a report on the location change type of the target terminal 100 but also a report on the exact location information of the location of the target terminal at a corresponding time in the location change state. Information that can be done. The location request flag may have a value of true or false. If the value is true, the exact location information is also reported. If the value is false, the location request flag is not reported.

At this time, the location service provider 200 has the following two functions as compared to the existing.

First, the location service provider 200 converts a specific area (target-area) designated by the location service user 100 into a format that can be recognized by the network. When the location service user 100 indicates a target area, a geographical name of area, a country code of the telephone number system, and a public land mobile network (PLMN) identity Use the form of. Therefore, the location service provider 200 converts the specific local information given in the above form into information that can be used when measuring the actual location. At this time, the specific type of local information that can be converted may be a radio cell identifier such as a location ID (LID), a location area, a routing area, or a location service user (100). You can use the country code, phone number, or PLMN identity of the phone number system already specified by).

Second, the location service provider 200 performs positioning with the target terminal 300 periodically, and determines whether the target terminal 300 is located in a specific area (target-area) designated by the location service user 100, and the location service After checking the change-area-type and service providing interval requested by the user 100, it is determined whether to report to the location service user 100.

In addition, the location change type and the service providing period may be combined and applied. That is, the location service provider 200 reports the location of the target terminal periodically and enters a specific area regardless of the period. The location service provider 200 may report at a different period from a previously set period in a specific region, and may report this again when leaving the specific region and report again at a previously set cycle.

The location measurement operation generated between the location service provider 200 and the target terminal 300 proceeds according to service start time information, service end time information, and service provision period information.

The location service provider 200 uses the location service request message transmitted from the location service user 100 to identify the target terminal 300 necessary for the location information and to authenticate the location service user 100 requesting the location information. Perform the process (S120).

That is, when the location service provider 200 receives the location service request message, the location service provider 200 identifies the target terminal 300 with the unique ID information 410 of the target terminal included in the location service request message, and identifies the target terminal 300. Check the corresponding privacy profile. The location service requested by the target terminal 300 is compared with the privacy profile of the target terminal 300, and the result is made into notification information.

In addition, the location service provider 200 performs location information request authorization and authentication (Authentication / Authorization) operation of the location service user 100 with the location information request authentication information 420 included in the location service request message. .

When the authentication for the location service user 100 fails in step S120, the location service provider 200 transmits a message (error message) indicating that the location service service provider refuses to provide the location information service to the location service. You can end the required operation. At this time, the location service provider 200 transmits a message (MLP TLRSR: Mobile Location Protocol Triggered Location Reporting Stop Request) indicating the end of the location information providing service to the location service user 100.

If the location information service access authority for the location service user 100 is authenticated in step S120, the location service provider 200 generates a location service initialization message (SUPL INIT: Secure User Plane Location Initiation) to perform the location service. Transmission to the target terminal 300 (S130). In this case, the location service provider 200 may transmit the location service initialization message to the target terminal 300 using a WAP push or a short message service trigger.

3 is a diagram illustrating a format of a Secure User Plane Location Initiation message used in the present embodiment.

As shown, the location service initialization message may include a session ID 510, a location service provider IP address 520, notification information 530 of the target terminal generated in step S120, and location service provider positioning. The description information (posmethod) 540, and reporting time information 550 is configured.

The session ID 510 is a name temporarily assigned to the target terminal 300 in order to exchange information necessary for providing location information between the target terminal 300 and the location service provider 200 in the future. The session ID 510 is generated by the location service provider 200 and added to the location service initialization message.

The location service provider IP address 520 is an IP address (SLP_IP address) of the location service provider 200 for enabling the target terminal 300 to connect communication to the location service provider 200.

Notification information 530 of the target terminal indicates a privacy profile test result for the target terminal 300 examined in step S120. The location service provider posmethod 540 is at least one piece of location technology type information that can be performed by the location service provider 200.

The report criteria information 550 is a service start time, service stop time, and service set by the location service user 100 to receive location information of the target terminal 300. Contains interval information. The report time information 550 may be time information set and transmitted by the location service user 100, but may use a pre-stored default time value of the location service provider 200.

The target terminal 300 examines the notification information 530 of the target terminal included in the location service initialization message and determines whether to allow or reject the provision of its location information.

In this case, the positioning may be optionally performed without the permission of the target terminal in a special case for the emergency or the elderly.

When allowing the location, the target terminal 300 generates a location service start message (SUPL start message) and transmits it to the location service provider 200 (S140).

4 is a diagram illustrating a format of a location service start message (SUPL start message).

As shown, the message for positioning includes a session ID 610, location setting method information 620, and network location information 630 of the target terminal.

The session ID 610 is the same information as the session ID 510 included in the location service initialization message (SUPL INIT) received in step S130. The SET capability information 620 is information indicating a positioning method of the target terminal 300, and indicates whether the target terminal is MS assisted A-GPS or MS-based A-GPS. Contains information about the positioning protocol to use {positioning protocol (eg, RRLP, RRC, IS-801, etc.)}.

The network location information 630 of the target terminal is a logical ID indicating a location on the network structure in which the target terminal 300 currently exists, such as a radio station identifier (Cell_ID). The network location information 630 of the target terminal is used when the location service provider 200 exchanges a message for positioning with the target terminal 300.

In addition to the above-mentioned information, the target terminal 300 displays the location service start message when there are other information that helps the location service provider 200 measure the location of the target terminal 300. Can be included in the transmission.

The location service provider 200 transmits a location information request response message {MLP TLRA (Mobile Location Protocol Triggered Location Reporting Answer)} to the location service user 100 to indicate the start of the requested location service provision (S150). When the location service provider 200 starts providing the location service, the location service provider 200 may or may not transmit the location information request response message to the location service user 100.

The location service provider 200 and the target terminal 300 exchange messages for positioning based on the report time information 550 included in the location service initialization message transmitted in step S130 (S160). The message exchange for positioning is necessary information exchange according to the positioning technology information (540 of FIG. 3) and the location setting method information (620 of FIG. 4) exchanged at step S140 of the location service provider 200 exchanged at step S130. do.

Through such a message exchange, the location service provider 200 obtains current location information on the target terminal 300 (S170). The acquired location information is stored in the location service provider 200 and / or the target terminal 300.

The location service provider 200 determines a change-area-type of the target terminal 300 for a specific region based on the currently acquired location information and previously obtained location information (S200). That is, the location service provider 200 determines the type of location change such as an entering state, a leaving state, a within state, etc. of the target terminal 300 for a specific region based on the acquired location information. .

5 is a flowchart illustrating a process of determining a location change type (reach, departure, presence) in step S200 of FIG. 1 in more detail.

First, the location service provider 200 stores location information transmitted from the target terminal 300 and determines whether the location information is located in a specific area (S210).

If it is determined that the target terminal 300 is located in a specific region, the location service provider 200 determines whether the target terminal 300 is information indicating that the target terminal 300 is located in a specific region (S220). .

When it is determined that the target terminal 300 is located in a specific region based on the previously stored location information and the current location information in steps S210 and S220, the location service provider 200 determines that the target terminal 300 is a location service user ( In operation S230, it is determined that the service is located in the specific area where the location service is requested.

On the other hand, if the location information previously stored in step S210 and step S220 is determined to be outside the specific area and the current location information is inside the specific area, the location service provider 200 is the target terminal 300 is the location service user 100 It is determined that the entry into the specific area (entering) requesting the location service from (S240).

On the other hand, if it is determined in step S210 that the target terminal 300 is not located in a specific area, the location service provider 200 is information indicating that the target terminal 300 is located in a specific area through previously stored location information. Determine (S250).

When it is determined in step S250 that the previously stored location information exists in a specific area, the location service provider 200 leaves the target terminal 300 to the outside in a specific area where the location service request is requested from the location service user 100. (S260).

If it is determined in step S250 that the previously stored location information exists outside the location information request area, the location service provider 200 determines that the target terminal 300 continues to be located outside the specific area (S270).

At this time, the location service provider 200 compares the determination result with the location change type information 470 received from the location service user 100 in step S110. The location change type information 470 is set by the location service user 100 with information included in the location service request message. For example, if the location service user 100 has requested the location change type information to report when the target terminal 300 enters a specific area, the location service provider 200 determines the target at step S200. The location change type information of the terminal 300 is compared with the location change type requested by the location service user 100 (S310).

As a result of comparing the two types of location change, if the two types are the same, that is, the location change type determined in step S200 is the same as the location change type for the specific area requested by the location service user 100, the location service provider 200 The reported location change type information to the location service user 100 (S300). The location change type information may include at least one of three types of entry, exit, and presence.

In addition, when the location request flag 480 is true in the location service request message, the location service provider 200 reports the exact location information of the target terminal 300 in addition to the location change type information.

As another embodiment of the present invention, the location service provider 200 may determine the location and location change type information of the target terminal 300 according to a specific period set by the location service user 100 or the location information provider 200. You can also report. This is different from the conventional method of providing only the location information periodically, which has the advantage of including the location change type information about the specific area set by the location service user 100 and reporting periodically.

The target terminal 300 according to the time interval (interval) of the report time information (550 of FIG. 3) included in the location service initialization message, as shown in step S140 location service start message location service provider 200 Transmit to restart the operation for the location information providing service (S410).

The location service provider 200 and the target terminal 300 exchange messages for positioning based on report time information (550 of FIG. 3) included in the location service initialization message transmitted in step S130, as in step S160 ( S420).

Through this process, the location service provider 200 obtains the location information and the location change type information of the target terminal 300, and selectively selects the location information and the location change type information of the obtained target terminal 30. In order to report to step 100, steps S170 to S330 are performed (S430).

When the service end time of the report time information (550 of FIG. 3) included in the location service initialization message is reached, the location service provider 200 transmits a service end message {SUPL END (session-id)} to the target terminal 300. By notifying that the session has ended (S440). In addition, the location service provider 200 transmits the location information and location change type information of the target terminal 300 obtained last to the location service user 100 (S450). When the target terminal 300 leaves the specific area where the location service is requested by the location service user 100, the location service provider 200 sends a service termination message {SUPL END (session-id) to the target terminal 300. } Can also be sent to indicate that the session has ended.

In the above, certain preferred embodiments of the present invention have been illustrated and described. However, the present invention is not limited to the above-described embodiments, and various modifications can be made by those skilled in the art without departing from the scope of the present invention, which is appended in the claims. It will be possible.

According to the present invention, by providing location information and location change type information to a location service user according to a region change with respect to a target terminal, a location change type (entry, entry, presence) of a user carrying the target terminal can be confirmed. have. Therefore, it is more convenient to check whether the elderly and minors are in or outside the safe area.
