2 is a view illustrating a SET-trigged case and a SET-initiated case in a SET assisted mode as a location-related location tracking procedure according to a second embodiment of the present invention.

The present invention relates to a mobile communication system, and more particularly, to a location-related location tracking method in a secure user plane location (SUPL) based location information system.

In the mobile communication system, the mobile communication network includes a related function unit for calculating the location of the terminal, and provides a location service for transmitting the location of the terminal to a certain entity periodically or at the request of the user. have. The structure of the network related to the location service is different depending on the internal network structure of 3GPP or 3GPP2.

The method for calculating the position of the terminal in the mobile communication system includes a cell-ID method for transmitting the ID of the cell to which the terminal belongs, measuring the radio wave arrival time from the terminal to each base station, and then using the triangulation to determine the position of the terminal. There are a method of calculation and a method using GPS.

However, in order to provide a location service to a user using the denture calculation method as described above, considerable signaling and location information must be transferred between the mobile terminal and the location server. Accordingly, standardized positioning technologies for providing location services, that is, location services based on the location of the mobile terminal, are rapidly spreading. The location technologies may be provided through a user plane and a control plane, and as an example of the technologies, a secure user plane location (SUPL) providing a location service through the user plane is known. have.

The SUPL is an efficient method for transmitting location information necessary for calculating a location of a mobile station. The SUPL is a user plane data bearer for delivering location assistance information such as GPS assistance and carrying a location technology related protocol between a mobile terminal and a network. Use

In general, a SPUL network related to location services in a location information system includes a SUPL agent, a SULP Location Platform (SLP), and a SUPL enabled terminal (SET). The SUPL agent represents a logical service access point using actual measured location information, and the SLP represents a SUPL service access point in a network 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 user terminal (UMTS) of a UMTS, a mobile station (MS) of a GSM, an IS-95 MS or a laptop computer having a SET function. Laptop computer) or PDA. Also, the SET may be various mobile terminals connecting through a WLAN.

The SET supports procedures defined in SUPL in association with a network through a user plane bearer. In this case, the network originally registered by the user is called a home network, and when the user moves and is located in an area other than the home network area, the network of the corresponding area is called a visited network. In addition, SLP in the home network is referred to as H-SLP (Home-SLP), and SLP in the visited network is referred to as V-SLP (Visited-SLP). In this case, when the SUPL procedure is started in the network, an SLP to which an external client first connects is called a requesting SLP (R-SLP), which may or may not be the same as the H-SLP as a logical entity. In addition, the SET that targets the current location tracking is defined as a target SET.

The SLP, which is a network element, actually plays a role of SLP (SUPL Positioning Center), which is an entity that calculates location, and a role of SLP other than calculating location information, for example, roaming and resource management. It consists of SLC (SUPL Location Center) that plays a role. Therefore, the SET may calculate location information through communication with the SPC via SLC (Proxy mode), or may directly connect with the SPC to calculate location information (Non-proxy mode).

However, the prior art proposes an immediate location tracking method based on SUPL, but does not present an area-based, area-related, area event triggered location tracking based on SUPL.

Accordingly, an object of the present invention is to provide a variety of effective location-related location tracking method based on SUPL.

Preferably, the first condition information indicates trigger type information, and the second condition information indicates trigger parameters.

Preferably, the trigger type information indicates a local event service type.

Advantageously, said trigger parameter represents a trigger parameter associated with a local event trigger location.

Hereinafter, preferred embodiments of the present invention will be described in detail.

The present invention is implemented in a SUPL network. However, the present invention can also be applied to a wireless communication system operating according to other standards.

According to the present invention, an area event triggered location tracking (a terminal moves to a specific location or continues to exist in a specific area) when a server and a terminal manage trigger information related to location tracking in a session-based location information system. Or move out of a particular area).

In the region-related location tracking according to the present invention, when an area event is generated by trigger information, the location server or the terminal starts a positioning procedure, so that the trigger information, that is, the area event. It is determined whether the terminal belongs to the region specified in the information, and reports the location of the terminal to the client that generated the region event when the terminal belongs to the region. Here, the occurrence of the local event indicates that the trigger condition is satisfied, and refers to a case where the terminal enters or exits a specific region or is confirmed to exist in the region. In addition, the area denotes information defining a local event in a word coincident with a “specific area” referred to in the present invention.

In general, location services provided by a SUPL-based location information system are classified into a network-initiated case and a SET-initiated case service. In addition, the SUPL-based location service includes a proxy mode in which the SET performs a positioning procedure by exchanging a message directly with an H-SLP of a home network, a SET SLC (SUPL Location Center) in the H-SLP, It is divided into Non-Proxy mode that performs positioning procedure by exchanging messages with SPL (SUPL Positioning Center), where SUPL-based location information system refers to session-based location information system.

According to the present invention, location services are classified into a network-trigged case or a SET-triggered case according to a subject managing trigger information for location tracking, and the classified services are classified by a network-initiated case and a SET. (SET-initiated case) The description is divided again into services.

1 is a diagram illustrating a location-related location tracking procedure according to a first embodiment of the present invention, which shows a SET-trigged case and a Network-initiated case in a SET assisted mode.

As shown in FIG. 1, when a location-related location tracking request is requested from an external LCS client, the SUPL agent transmits a Mobile Location Protocol (MLP) Triggered Location Reporting Request (TLRR) message to the SLP (S10).

The MLP TLRR message includes parameters such as ms-id, client-id, QoP, and tlrr_event. The ms-id represents a target SET, and the Qop represents a location tracking accuracy (temporal delay and spatial accuracy). In addition, the tlrr_event is a location-related trigger parameter, for example, the nature of location-related location tracking (move to or out of a specific area or within a specific area) and a specific area (name of a specific area or Varying degrees of condition information related to location tracking, such as exact location values).

The MLP TLRR message additionally includes the type of location tracking value (expression of whether it is the current location tracking value or the most recently tracked value), and the priority of each location tracking request when there are several location requests. Parameters that can be set may be included.

Upon receiving the MLP TLRR message, the SLP checks whether a target SET (hereinafter, abbreviated SET) supports SUPL using a lookup table and checks whether the SET is currently SUPL roamed using routing information. (S11).

If it is determined that the SET supports SUPL and is not currently roaming, the SLP sends a SUPL INIT message to the SET to start a local event triggering session with the SET (S12). The SUPL INIT message may be transmitted in the form of a wireless application protocol (WAP) push or a message short message service (SMS) trigger or a session initiation protocol (SIP) push or UDP / IP.

The SUPL INIT message includes at least a session-id, a trigger type indicator (e.g., area event), an SLP mode (proxy / non-proxy), a location tracking method (posmethod) to be used, and the like. In addition, the SLP may confirm the privacy of the SET before performing the step S11. If the user needs a notification related to the location information, the SLP may set a notification parameter in the SUPL INIT message. May be additionally included.

As such, the SLP transmits the trigger type in the SUPL INIT message, so that the SET knows that the current location-related location tracking has been requested, and the location tracking is performed by the SLP initiative (Network-trigged case).

Receiving the SUPL INIT message, the SET recognizes that the SLP uses the proxy mode, and establishes a secure IP connection with the SLP. In addition, the SET establishes a data connection with the packet data network (3GPP or 3GPP2) when it is not currently established in any network (S13). Once the data connection is established, the SET sends a SUPL TRIGGER START message to the SLP to start an area event triggered session (S14). The SUPL TRIGGER START message includes at least session-id, lid and SET capability information.

When the SUPL TRIGGER START message is received, the SLP selects a location tracking method to be used for a local session from the SET capability, and sends a SUPL TRIGGER RESPONSE message including the session-id, posmethod, and trigger parameters (trigger_params) to the SET. (S15). The trigger parameter represents an area event triggered parameter related to location tracking. The trigger parameter is part of a parameter associated with a local event trigger.

For example, the trigger parameter may include trigger condition information indicating a characteristic of a local event and a specific region. The nature of the local event may indicate whether or not to move into or out of a particular area. The SUPL TRIGGER RESPONSE message may also include location identifiers (lids) of a region defined for a region related session. Preferably, the location id is an ID of cells belonging to an area where the SUPL agent requests location tracking, a mobile country code (MCC), a mobile network code (MNC), or a location area code (LAC). Information indicating a location area on an actual network or a primary scrambling code number. In particular, in the case of WCDMA, it corresponds to a primary scrambling code number.

In addition, the SLP informs the SUPL agent that the location tracking request has been approved through an MLP Triggered Location Reporting answer (TLRA) message (S16).

If the location id (s) are received through the SUPL TRIGGER RESPONSE message, the SET transmits a SUPL location tracking initialization message (SUPL POS INIT message) to the SLP only when the trigger condition is satisfied.

For example, whether the trigger condition is satisfied may be checked by comparing a location identifier of a current SET with location identifiers received from the SLP. That is, the SET compares the cell id of the cell in which the current SET is located with the plurality of received cell ids, and checks whether a matching cell id exists.

If the character of the local event included in the trigger parameter enters or is located in a specific region, the SET performs periodic location tracking when at least one of the received location identifiers matches the location identifier of the current SET. To start. On the other hand, when confirming a case where the nature of the local event comes from a specific region, the SET starts periodic location tracking only when the received location identifiers do not match the current location identifier of the SET.

This comparison is to check if the current SET is close to the area requested by the SUPL agent through the approximate location calculation of the SET.

If the trigger condition is found to be satisfied through the comparison of the location identifiers, the SET recognizes that the user has approached the currently requested area, and sends a SUPL POS INIT message to the SLP for positioning. ) Start the session (S17). The SUPL POS INIT message includes at least a session-id and a location identifier.

The SLP and the SET calculate the position of the SET by exchanging successive messages for performing the actual position tracking (S18). Preferably, the messages exchanged between the SLP and the SET include a session ID and a protocol (RRLP, RRC or TIA-801) to be used for location tracking. The position calculation of the SET may be performed based on the measured value received by the SLP from the SET (SET-assisted mode), or may be performed based on the assistance obtained by the SET from the SLP (SET-based mode). In this embodiment, since the position calculation is performed by the SET assisted mode, the SLP transmits the calculated position value to the SET through the SUPL REPORT message (S19). When the position calculation is performed by the SET based mode, the SUPL REPORT message is not necessary.

Therefore, when the position value (posresult) of the SET is received from the SLP, the SET checks the calculated position value and the position value of the specific region defined in the trigger parameter to check whether the trigger condition is satisfied, that is, whether the local event has occurred. Compare (S20).

As a result of the comparison, if the position value of the SET matches the position value defined in the trigger parameter (when a local event occurs), the SET performs the operation after step S25, and if it does not match, the SET returns a SUPL POS INIT message. By transmitting to the SLP again to inform the start of the positioning session (S21). Thereafter, the SLP and the SET exchange the successive messages for performing the actual position measurement to calculate the position of the SET (S22), and the SLP transmits the calculated position value (posresult) to the SET through the SUPL REPORT message (S23). .

When the position value (posresult) of the SET is received from the SLP, the SET compares the calculated position value with the position value of the specific region defined in the trigger parameter, and checks whether a region event has occurred (S20). As a result of the comparison, if the local event does not occur, the SET repeatedly performs the steps S21 to S23, and if it matches, transmits a SUPL REPORT message to the SLP (S25). The SUPL REPOET message includes at least a session-id and a location that caused the local event.

Therefore, the SLP transmits the location-related location tracking value to the SUPL agent through the TLREP message (S26), and transmits the SUPL END message to the SET to inform the end of the positioning session (S27). The SET receiving the SUPL END message terminates the IP connection with the SLP and releases all resources related to the positioning session.

FIG. 2 is a diagram illustrating a location-related location tracking procedure according to a second embodiment of the present invention, and illustrates a SET-trigged case and a SET-initiated case in a non-roaming proxy mode.

As shown in FIG. 2, when an area event triggered service is requested from a SUPL agent inside a SET, the SET establishes a data connection with the packet data network if the data connection is not currently established in any network. (S30).

When the data connection is established, the SET establishes a secure IP connection with the H-SLP using the default address provided from the home network, and initiates a positioning session by transmitting a SUPL TRIGGER START message to the SLP (S31). . The SUPL TRIGGER START message includes at least a session-id, trigger type indicator (e.g., area event), lid, SET capabilities, and trigger parameters (trigger_params).

The trigger parameter represents an area event triggered parameter related to location tracking. The trigger parameter is part of a parameter associated with a local event trigger.

The trigger parameter may include trigger condition information, for example, the nature of a local event and a specific region. The nature of the local event may include condition information indicating whether to move into or out of a specific region or within a specific region.

Receiving the SUPL TRIGGER START message, the SLP determines which cells belong to a specific region in the trigger parameter, and then stores location identifiers (lids) of the region and transmits them to the SET through a SUPL TRIGGER RESPONSE message. S32). Preferably, the location id corresponds to any one of an ID of cells belonging to an area where a SUPL agent requests location tracking, an MCC, an MNC, a LAC, a primary scrambling code number, or a primary scrambling code number.

The SET receiving the location id through the SUPL TRIGGER RESPONSE message transmits a SUPL location tracking initialization message (SUPL POS INIT message) when the trigger condition is satisfied. That is, the SET compares the position identifier of the current SET with the received position identifiers (S33). For example, the SET compares the cell ID where the current SET is located with the plurality of received cell IDs, and checks whether there is a matching cell ID.

If the character of the local event included in the trigger parameter enters or is located in a specific region, the SET performs periodic location tracking only when at least one of the received location identifiers matches the location identifier of the current SET. To start. On the other hand, when confirming a case where the nature of the local event comes from a specific region, the SET starts periodic location tracking only when the received location identifiers do not match the current location identifier of the SET.

This comparison is to check if the current SET is close to the area requested by the SUPL agent through the approximate location calculation of the SET.

As a result of the comparison, if at least one of the received location identifiers matches the location identifier of the current SET, the SET recognizes that it has accessed the currently requested area and sends a SUPL location initialization message (SUPL POS INIT message) to the SLP. Initiate a positioning session by transmitting (S34). The SUPL POS INIT message includes at least a session-id and a location identifier (lid).

The SLP and the SET calculate a position of the SET by exchanging successive messages for performing actual positioning (S35). In this case, the position calculation of the SET may be performed based on the measured value received by the SLP from the SET (SET-assisted mode), or may be performed based on the assistance obtained from the SLP by the SLP (SET-based mode). 2 shows that the position calculation is performed by the SET based mode, but if the position calculation is performed by the SET assisted mode, the SLP transmits the position value calculated by the SET using the SUPL REPORT message (S36).

When the position value of the SET is calculated, the SET compares the calculated position value with the position value of the specific region defined in the trigger parameter to check whether the trigger condition is satisfied, that is, whether a local event has occurred (S37). . As a result of the comparison, if the trigger condition is not satisfied, the SET calculates a new position value by performing steps S38 to S39. At this time, when the position calculation is performed by the SET assisted mode, the SLP transmits the position value calculated by the SET using the SUPL REPORT message (S40).

When the new position value is calculated, the SET compares the calculated new position value with a position value of a specific region defined in the trigger parameter to check whether a trigger condition is satisfied (check whether an local event has occurred) (S41). If the trigger condition is satisfied, the SET reports the measured new position value to the internal agent and transmits a SUPL END message to the SLP (S42).

As described above, the present invention proposes a method for performing location-related location tracking in a location tracking method based on SUPL so that various location tracking methods can be implemented based on SUPL.

Although the present invention has been described with reference to the embodiments shown 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.
