The present invention provides an interface between the location information system reflecting the user's preference information and each entity (entity), and proposes a method for activating the user preference information set in the region when the user moves to a preset location (or region) do.

In the present invention, the location information system reflecting the user's preference information refers to an operation of differently setting the operation and function of the terminal in a specific region designated by the user. For example, a user may set a ring tone of a terminal as a vibration in a company and set it as a bell at home, and may not set an international call or receive a data service at home. Therefore, when the user enters a specific region, such that the preference information preset by the user is activated, etc. belong to the location information system according to the present invention. To this end, a related entity must be added to activate a specific terminal operation in a specific region, and an additional interface between the entities is required.

In addition, the present invention stores the user's preference information in a user preference repository (eg, Privacy Check Entity: PCE) that is a network entity, when the location tracking for the user is requested, the actual location value of the user Instead of reporting (e.g., x, y, z coordinates), we propose a method of reporting a proxy location (representative location) that reflects user preference information, which is a value representing a user's preset location. . The representative location report identifies a profile (PCE) in which user preference information is stored, and compares the user's actual location value with preset preference information when the user requests location tracking to represent the user's actual location. It means reporting the representative position. The representative position represents a position set for each range of a preference zone set by a user. In this case, several regions may be set as one representative position, and a representative position may be set differently for each of the regions. In addition, the region set as the preference region and user preference information in each preference region may be set or modified only by an authorized user.

1 is a configuration diagram of a location information system according to the present invention.

As shown in FIG. 1, the location information system according to the present invention includes a storage medium 10, a location server 11, a source server 12, and a user terminal 13.

The storage medium 10 is a network entity existing in a part of a wireless network, for example, implemented as PCE. The storage medium 10 stores user preference information (= surrogate location) set for each user preference information or user preference zone (Preference Zone) related to the terminal operation in a specific region.

The location server 11 includes a subscriber profile function unit, a location calculation function that calculates a location of a current terminal (user), and other entities required to support location services. The subscriber profile function unit provides information on whether a service for a terminal operation (hereinafter, referred to as a preference information service) in a specific region (eg, preference information service ON or OFF) and user preference information zone designated by the user is specified. Save it. Conventional entities in charge of location services do not perform a function related to preference information according to a user's location, so it may be said that a specific entity in charge of the preference information related function is required.

The subscriber profile function unit stores information on a preference information area and information on whether a preference information service is set, and when a user moves and is located in a specific region, a specific terminal operation (preferred information) designated by the user is activated. Follow the appropriate procedures to help. That is, the subscriber profile function unit notifies the origin server 12 when the user moves to the user preference information area designated by the user, and enables the origin server 12 to activate the preference information set by the user. . In this case, the raw server 12 may request and receive user preference information in a specific region stored in the storage medium 10.

In addition, the subscriber profile function unit compares the user's actual location value provided from the location calculation function unit with the preference information stored in the storage medium 10 when the user's tracking request is requested, and the proxy location set in the user preference information. Report.

The location information system according to the present invention includes an origin server 12 for activating specific preference information set by the user. The location of the origin server 12 may vary depending on the structure of the wireless network. In the present invention, the entity responsible for activating specific preference information according to the location of the user is referred to as a origin server.

The origin server 12 may be a physical entity that exists independently, or may be included in one entity existing in the existing wireless network structure. Therefore, in order to activate the operation of the specific terminal 13 in some regions designated by the user, between the location server 11 and the source server 12, between the storage medium 10 and the source server 12, and the source server 12 and The interface between the terminals 13 should be defined separately. In addition, in the present invention, the storage medium 10 and the raw server 12 are separately displayed, but in another embodiment, the storage medium 10 may be included in the raw server 12.

The present invention sets an operation of a specific terminal according to a user location, and adds a field in the interface between the terminal 13 and the storage medium 10 to transmit preference information for each location of the user. That is, a field for transferring preference information is added to a data transmission format between the terminal 13 and the storage medium 10.

The storage medium 10 stores user preference information for a specific region, and the location server 11 determines whether the user has moved to the preference information area set by the user and notifies the raw server. Therefore, the source server 12 activates the preference information (specific operation) of the terminal 13 designated by the user when the user moves to the user preference information area.

In addition, the interface operation between the entities shown in FIG. 1 is as follows.

Request (raw server 12-> storage medium 10): It is used when a user requests preference information related to a specific terminal operation in a specific region from the storage medium 10. In this case, the response is a response to the request.

Request (user terminal 13-> storage medium 10): It is used when the user wants to store preference information for a specific terminal operation at a specific location. The response is a response to the request.

Request (user terminal 13 → location server 11 (subscriber profile function): used when the user wants to set a specific location as the user preference information area, where the response can be said to be a response to the request. .

Request (raw server 12-< / RTI > user terminal 13): It is used when the raw server 12 activates a specific terminal operation (preferred information) designated by the user when the user moves to a specific position. In this case, the response may be referred to as a response to the request.

Finally request (Location server 11 (subscriber profile function) → raw server 12: is used when the subscriber profile function detects that the user has moved to a specific location and informs the origin server 12 of this situation. In this case, the response is a response to the request.

2 is a flowchart illustrating a user preference information service method in a location information system according to an exemplary embodiment of the present invention.

Referring to FIG. 2, the user operates the menu of the terminal to set the preference information service to ON. In this state, the user sets user preference information in the preferred regions and the corresponding preferred region (S10). Preferably, the preference information indicates an operation of the terminal or a representative location representing the actual location of the user.

In this case, one or more regions (locations) may be set (registered) as one user preference region. Therefore, since the user may set several regions as the user preference region, the user may set a plurality of preference information for each specific location (or region).

The preference information for the specific region designated by the user is stored in the storage medium 10 through an interface (S11), and setting the preference region (for example, cell id of the corresponding place) and preference information service (ON). Or OFF state) is transmitted to the location server 11 and stored in the subscriber profile function. In this case, the storing operation is performed in response to the request of the user profile storage medium 10 according to the request of the terminal and in response to the request of the location server 11.

Thereafter, the location subscriber profile function checks whether the preference information service is set or requests the user's location to the location calculation function, which is a location information calculation object in the location server 11, when the user requests location tracking (S12). It is checked whether the current user's location is included in a specific preference area (S13). As a result of the check, the subscriber profile function notifies the source server 12 when the current user's location is included in the registered specific preference area, and if the current user's location is not included in the specific preference area, the step ( Return to S12).

Therefore, the source server activates the preference information set by the user in the specific preference area, for example, the operation, function, and location reporting method of the specific terminal (S14). At this time, since the user preference information is stored in the storage medium 10, the raw server 12 requests the delivery of the preference information to the storage medium 10 so that the corresponding preference information can be activated in the user's terminal. In particular, when the preference information indicates a representative location representing the actual location of the user, the subscriber profile function unit compares the user's actual location provided from the location calculation function unit with the preference information stored in the storage medium 10, and user preference information. Report the proxy location set in.

As such, when the terminal moves to a specific area, the location calculation function performs a location measurement procedure with the terminal 13 to provide the current location of the user to the subscriber profile function. In this case, a signal procedure between the location server and the terminal is required. . Accordingly, the present invention provides a signaling procedure in a location information system based on Secure User Plane Location (SUPL).

SUPL is an efficient way of delivering location information needed to calculate the location of a mobile station. It is used to deliver location assistance information such as GPS support and to carry positioning technology-related protocols between the mobile terminal and the network. Use a planar data bearer.

In the SUPL-based location information system, the SPUL network related to location services includes SUPL Agent, SLP (SUPL Location Platform) and SET (SUPL Enabled Terminal). The SUPL agent represents a logical service access point using actual measured location information, and the SLP represents a SUPL service access point of a network portion that accesses network resources to obtain location information. The SET is a device capable of communicating with a SUPL network using a SUPL interface, for example, a UE (User Terminal) of UMTS, a Mobile Station (MS) of GSM, an IS-95 MS, or a Laptop Computer having a SET function. PDA and the like. Or it may be a variety of mobile terminals connected via a WLAN. The SET interworkes with the network through a user plane bearer to support definition procedures in SUPL. Accordingly, in FIG. 1, the terminal 13 and the wireless network may be implemented in the form of a SUPL network, an SLP corresponds to a location server, and a SET corresponds to a terminal.

The present invention provides a user with a location of a SET according to a location tracking request (Standard Location Immediate Service) or a predetermined time interval or a specific event (Triggered Location Reporting Service). The specific event is a situation where a user using SET enters or exits a specific area, or an event within which a user and a terminal are unable to estimate the location (when communication is not possible in the underground). When this is possible, several events can be included, such as announcing the event.

The present invention then explicitly informs the start of the SUPL Positioning procedure. To this end, the present invention informs the SPUL network of the start of the SUPL location measurement procedure using the SUPL REPORT. This may use the SUPL START message instead of the SUPL REPORT to inform the SLP of the start of SUPL positioning. Hereinafter, positioning is referred to as positioning.

First, the present invention first describes a position measurement procedure in the SUPL network.

In general, SUPL location services can be classified into network-initiated services and SET-initiated services.

3 is a message flow diagram illustrating an embodiment of a SET initiated Location Reporting service according to the present invention. In this case, in general, SLP represents a wireless network side and SET represents a terminal side, and a SUPL agent may exist in both the network and the terminal side or may exist as a separate object.

Referring to FIG. 3, the SUPL agent of the SET sends a SUPL START message to the SLP in order to start a positioning procedure by starting a Positioning Session with the SLP (S20). The SUPL START includes parameters such as session ID, SET capabilities, local identifier (lid), and reporting criteria. The SET capabilities include supported location methods (e.g., MS assist A-GPS and MS based A-GPS, cell-id method) and associated location measurement protocols (e.g., RRLP, RRC, IS-801). In addition, the SET may additionally provide NMR for the radio technology (e.g., GSM: TA, RXLEV) used.

The reporting criterion is a criterion used to report a specific event or a user's location. In the case of periodic location measurement, the reporting criterion may include a starting point, a period, and an ending point of the location tracking. You can also set criteria to notify you when a user enters, exits from, or exists in an area. In this case, the name of a specific region or latitude and longitude information of the specific region may be included as a reporting criterion. In addition, events related to a specific region and periodic events may be combined with each other.

For example, the report location may include a proxy location in which user preference information is reflected. The representative location is preference information representing the actual location of the user, and indicates a location set for each range of the preference zone set by the user. Thus, if a user is requested to track a location when he is in an area (preferred area) set to "Home", the SET will report the user's actual location value (e.g. x, y, z coordinates). Rather, the value representing the user's pre-set "home" (eg postal code, community name or region name) is reported.

When a SUPL START message arrives from the SET, the SLP will check the protocol included in the SUPL START message to determine which location protocol to use. After the location tracking is requested, the SET transmits a SUPL REPORT message to start the SUPL positioning procedure to the SLP (S21). At this time, the SUPL report message includes a session ID and event_trigger. In this case, the SUPL START message and the SUPL REPORT message may be combined. In other words, by sending a SUPL START message when a specific event occurs, the SUPL related procedure can be started while notifying that a specific event is issued. When the SUPL START and the SUPL REPORT are separated as above, the SUPL START message starts the procedure related to SUPL, and then shows the general case of sending the SUPL REPORT message when a specific event occurs.

Accordingly, the SLP performs the SUPL positioning procedure of sending and receiving SUPL POS messages according to the SUPL REPORT message (S22). In this case, the SLP calculates the position estimate based on the measurements received from the SET (MS Assisted), or the SET calculates the position estimate based on the Assistance obtained from the SLP (MS Based). If the SLP calculates the position estimate based on the position measurement value received from the SET (MS Assisted), it should inform the SET. For this purpose, a separate SUPL REPORT message may be sent and the calculated value may be delivered in the message. In addition, at the end of the SUPL POS procedure, when the SLP calculates the position estimate based on the position measurement received from the SET, the SUPL POS message from the SLP to the SET may be transmitted once more.

When the location calculation is completed, the SLP sends a Location Privacy Assertion Request message to the PCE to request preference information of the SET to be tracked (S23), and the PCE sends a Location Privacy Assertion Response message including the preference information of the SET to the SLP. (S24).

Therefore, the SLP checks whether the calculated user's location is included in the specific preference area, and reports the calculated user's location as a SET when the current user is included in the registered specific preference area. In the present invention, rather than reporting the actual location of the user, the preference information representing the preferred area, that is, the representative location is reported as a SET, the representative location is included in the SUPL END message indicating that the location session is completed because the location measurement procedure is completed (S25).

4 is a message flow diagram illustrating another embodiment of a SET initiated Location Reporting service according to the present invention, and shows an example in which the SLP and the SET exchange SUPL POS messages several times in succession.

As shown in FIG. 4, the SUPL agent on the SET sends a SUPL START to the SLP to start the location procedure by starting the location session with the SLP (S30), and the SLP sends and receives a SUPL POS message to the SET. Perform the position measurement procedure (S31).

For example, for a SET-based operation mode, that is, a mode in which the SET calculates a position estimate based on assistance from the SLP, the SET and the SLP exchange SUPL POS messages to provide necessary support data. The terminal position is calculated in the SET.

Also, the SET and SLP exchange SUPL POS messages for the SET assisted operation mode, that is, the mode in which the SLP calculates the position estimate based on the position measurement value received from the SET, in which case the terminal position is calculated in the SLP. do. In particular, in the SET assisted mode, the SLP may perform an optional procedure of reporting the calculated position estimation value to the SET through a SUPL REPORT message (S32), where the SET is required to be SLP before SUPL POS. An additional procedure to send a SUPL START message to the server is performed. The step S32 may be repeatedly performed once per interval, that is, in steps S35 and S38, if necessary, and the step S33 may be repeatedly performed in step S36.

5 is a message flow diagram illustrating another embodiment of a SET initiated Location Reporting service according to the present invention. 5 is basically the same as FIG. 4 except that an additional procedure of reporting the position estimate to the SET in the SUPL END message is performed instead of using the SUPL REPORT message separately. In FIG. 5, the calculated position estimate value is included in the SUPL END message as a SET without including the calculated position estimate value at the end of the SUPL POS procedure, and the SUPL END may be used only for terminating the SUPL procedure.

In the present invention, a network initiated location reporting service is classified into a triggered location reporting service and a stand location immediate service. The Triggered Location Reporting service is a service that provides location information of a SET when a predetermined time interval or a specific event occurs, and the Standard Location Reporting service is a service used for immediately requesting a response to a location request.

6 is a message flow diagram illustrating an example of a triggered location reporting service by a network according to the present invention.

Referring to FIG. 6, the SUPL agent sets a location reporting condition (event) through a Mobile Location Protocol (MLP) Triggered Location Reporting Request (TLRR) message (S40). In this case, the MLP TLRR message includes an ms-id, a location service client (lcs) -client-id, and an event to be triggered (conditionally) (tlrr_event). In this case, the location reporting condition may include an operation of a specific SET (UE available), a time interval, and a change of area. When one of the conditions occurs, the location reporting may be performed. will be.

The SLP authenticates the SUPL agent based on the received client-id and performs a subscriber privacy check on the client-id based on the ms-id. Once the SUPL agent authentication is completed, the SLP sends a SUPL INIT message, which may be a WAP PUSH or SMS trigger, to the SET (S41) to start a location session with the SET. The SUPL INIT message includes at least a session ID, an address of the SLP, a posmethod, triggered reporting criteria, and the like.

If the privacy check indicates that the SET needs to be notified or confirmed, the SLP will include a notification element in the SUPL INIT message. When the SUPL INIT message is received from the SLP, the SET infers the notification rule and transmits the SUPL START message to the SLP to execute the SLP and SUPL POS session (S42).

The SUPL START message includes at least session ID, SET capabilities and location identifier (lid). The SET capabilities are the same as in the case of the location request by the SET of FIG. 3, supported positioning methods (eg, MS assist A-GPS and MS based A-GPS, cell-id method) and related positioning protocols (eg , RRLP, RRC, IS-801). In addition, the SET may additionally provide NMR for the radio technology used (e.g., GSM: TA, RXLEV).

When a SUPL START message arrives from the SET, the SLP will examine the SUPL START message and determine which location protocol (RRLP, RRC, IS-801) to use. When the location protocol to be used is determined, the SLP sends an MLP Triggered Location Reporting Answer (TLRA) indicating to the SUPL agent that a location session is in progress for the required triggered location report (S43).

Then, if the required event occurs, the SET transmits the SUPL REPORT message indicating the start of the SUPL positioning procedure to the SLP (S44), and the SLP starts the SUPL positioning procedure according to the SUPL REPORT message (S45). . In this case, SLP and SET can exchange SUPL POS messages several times in succession.

In the SUPL positioning procedure S45, the SLP calculates a position estimate based on the positioning values received from the SET (MS Assisted). The positioning may be performed based on the assistance that the SET obtains from the SLP. (MS Based). You can also use the SUPL START message instead of the SUPL REPORT message. If the SET calculates the position estimate based on assistance obtained from the SLP (MS Based), the SET should inform the SLP of the calculated value, which may be performed at the end of the SUPL position measurement procedure or a separate SUPL REPORT Messages can also be used, which will be explained in other examples below.

When the location calculation is completed, the SLP sends a SUPL END message to inform the SET that the location measurement procedure is completed and the location session is terminated (S46). Check if it is included in the area. If the calculated user's location is included in the registered specific preference area, the SLP is not the user's actual location but the preference information representing the preference area, that is, the representative location as the SUPL agent through MLP TLREP (Triggered Location Report) message. It transmits (S47).

FIG. 7 is a message flow diagram illustrating another embodiment of a triggered location reporting service by a network, and illustrates an example in which an SLP and a SET exchange a SUPL location measurement procedure message several times in succession. In this embodiment, the SET uses the SUPL START message to start the positioning procedure while informing the SLP that a particular event has occurred, which is different from FIG. In particular, in FIG. 7, when the SET calculates the position estimate based on assistance obtained from the SLP (MS Based), the SET should inform the SLP of the calculated value, in which case the position estimate calculated using the SUPL REPORT message. It is different to perform the additional procedure of reporting a value to SET.

8 is a message flow diagram illustrating an example of a Standard Location Reporting service by a network according to the present invention.

As shown in FIG. 8, the SUPL agent requests location information through an MLP SLIR (Standard Location Immediate Request) message (S50). The MLP SLIR message includes ms-id, client-id and qos. The SLP performs SUPL agent authentication and subscriber privacy check and then sends a SUPL INIT message to the SET (S51) to start a location session with the SET. The SUPL INIT message includes at least a session-id and an SLP address, and includes a notification when a notification or confirmation is required to the SET as a result of the privacy check.

When the SUPL INIT message is received from the SLP, the SET establishes a data connection with the SLP according to the address received from the SUPL INIT message, and then executes the SUPL POS session through the SUPL POS INIT (S52). The SLP determines the position measurement protocol (RRLP, RRC, IS-801) to be used through the SUPL POS session from the SET and then starts the SET and SUPL positioning procedure (S53).

After the position calculation is completed, the SLP sends a SUPL END message to inform the SET that the position measurement procedure is completed and the position session is terminated (S54). In addition, the SLP requests PCE preference information of the SET and checks whether the calculated user's location is included in a specific preference area. If the calculated user's location is included in a registered specific preference area, the SLP determines the user's actual information. Instead of the location, the preference information representing the preferred area, that is, the representative location is transmitted to the SUPL agent through an MLP SLIR (Standard Location Immediate Answer) message (S55).

The present invention can store the user's preference information in a network entity (e.g., PCE) rather than in the terminal itself so that the preference information function can be activated according to the user's location. In the present invention, preference information is executed according to the following two cases.

The first method is a case in which the corresponding terminal application is an execution agent. The user sets user preference information in the terminal application, and the corresponding application receives the current position of the terminal from a location enabler in the terminal and corresponds to the current position. To execute the set preference information (representative location report).

The second method is a case in which the location enabler of the terminal is an execution agent. The location enabler transmits the location information of the terminal to the corresponding terminal application, and the application executes user preference information according to the terminal location.

Both methods can report location information at a predetermined time interval (periodically) or when a specific event is triggered, or report immediately upon actual location information request.

The above two methods are distinguished according to the subject of execution, but the contents of executing the user preference information differently according to the location are the same. Therefore, when the above embodiment is applied, the corresponding function may be executed in cooperation with the location enabler and applications in the terminal without storing user preference information in a storage medium which is a network entity.

The user sets the preference information service to ON by manipulating the menu of the terminal and sets desired information (operation and location reporting method of the specific terminal) for each preference region (S60). In this case, the user may set several regions as the preference information region.

Therefore, the preference information is stored in the terminal application, and information of the preferred region (for example, cell id of the corresponding region) designated by the user is also stored in the location enabler in the terminal (S61).

Therefore, the location enabler causes the location server to inquire about the location of the user periodically or when the user enters the user's preset preference area when the user turns on the preference service. It requests to inform that the corresponding event has occurred (S62).

Thereafter, when the user is located in any one of the preset preference areas, the location enabler or the terminal application executes the preference information set in the preference area (S63 and S64). That is, when the terminal application is the execution subject, the application requests the current location of the terminal from the location enabler and outputs preference information according to the current terminal location, for example, the representative location. On the other hand, when the location enabler is the execution agent, the location enabler delivers location information to the corresponding terminal application, and the application outputs the representative location corresponding to the current terminal location.

As described above, the present invention has the effect of satisfying the user's desires in various ways by differently setting the information displayed on the terminal according to the user's location and the preference information for the operation method of the terminal and the reporting method of the user's location. There is.

In addition, the present invention provides a message delivery system between each SUPL element in the SUPL network for the location measurement between the terminal and the location server, in particular by sending a SUPL REPORT message that the SET explicitly informs the start of the SUPL location measurement to the SLP There is an effect that can effectively perform SUPL positioning in the network.

Although the present invention has been described with reference to the embodiments illustrated in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
