The present invention relates to an apparatus and method for reporting location information of a terminal.

As the number of users intending to transmit/receive data while moving has recently increased, a location based service (LBS) as a main service of the mobile communication field has received substantial interested. An LBS is a service that rapidly and conveniently provides various information related to a moving user's location to a base station through wireless and/or wired communication.

In order to provide the LBS, a wireless location measurement technology is needed. The wireless location measurement technology performs a role of determining the user's location using a satellite system or a mobile communication network.

At this time, as a method for allowing a terminal to report the location information, there are a method for reporting the location information after a predetermined time elapses and a method for reporting the location information when the base station requests the location information. However, these methods cause an unnecessary report when the movement speed of the terminal is slow or the terminal is an idle mode.

Hereinafter, a method and apparatus for reporting location information of a terminal according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a diagram showing a wireless communication system according to an exemplary embodiment of the present invention, and FIG. 2 is a diagram showing an apparatus for determining location and an apparatus for reporting location information according to an exemplary embodiment of the present invention.

Referring to FIG. 1, a wireless communication system includes a base station 10 and a terminal 20.

The base station 10 uses a radio resource of a downlink frame to perform communication with a terminal 20 and the terminal 20 performs communication with the base station 10 using a radio resource of an uplink frame.

The terminal 20 may have a location determination mode and an information reporting mode as location determination modes. The location determination mode is a mode that performs final location determination or final location confirmation in the terminal 20, and the information reporting mode is a mode that performs the final location determination and the final location confirmation in the base station 10.

According to an exemplary embodiment of the present invention, the terminal 20 is operated in the information reporting mode, and the terminal 20, which is operated in the information reporting mode, reports the varing location information of terminal to the base station 10.

The base station 10 includes an apparatus 100 for determining location, and the terminal 20 includes an apparatus 200 for reporting location information.

The apparatus 100 for determining location determines a wireless location meansurement type, and transmits an indicator of the terminal 20, that indicates the determined wireless location meansurement type and an indicator that indicates a location measuring parameter necessary for the determined wireless location meansurement type to the apparatus 200 for reporting location information, thereby requesting the location information to the apparatus 200 for reporting location information. However, as the LBS can be initiated not only by the base station but also by the terminal, the terminal can also collect and report the location information without the request of the base station. The terminal according to the embodiments of the present invention can support a per-request reporting mode, a periodic reporting mode, and an event-triggered reporting mode.

Then, the apparatus 100 for determining location receives the location information corresponding to the location measuring parameter from the apparatus 200 for reporting location information, and determines the final location of the terminal 20 using the location information corresponding to the received location measuring parameter.

In the case of the technology for measuring the location information corresponding to the location measuring parameter, for example, the time difference of arrival (TDOA), the apparatus 200 for reporting the location information collects the TDOA information and reports the collected location information to the apparatus 100 for determining location whenever the reporting condition of the location information is satisfied.

Referring to FIG. 2, the apparatus 100 for determining location includes a controller 110 and a determining unit 120.

The controller 110 determines the wireless location measurement type and determines the location measuring parameter necessary for the determined wireless measuring technology. The controller 110 transmits an indicator that indicates the determined wireless location measurement technology, an indicator that indicates the location measuring parameter, and a reporting period of the location information to the apparatus 200 for reporting location information to request the report of the location information to the apparatus 200 for reporting location information. At this time, the controller 110 can change the reporting period according to the moving speed of the terminal 20 and the state of the terminal 20. For example, when the moving speed of the terminal 20 is slow, the reporting period can be set to be long.

As the wireless location measurement technology, there are a technology of using a terminal including a GPS receiving apparatus, a technology of measuring time of arrival (TOA) between a terminal and a base station, a technology of measuring time difference of arrival (TDOA) from two different base stations, a technology of measuring direction of arrival (DOA) or angle of arrival (AOA) of signals in a terminal, and a cell-ID technology.

The cell-ID technology is a technology that determines the location of the base station 10 as the location of the terminal 20 when the terminal 20 is registered in the base station 10 using an ID allocated to the base station 10. In the case of the cell-ID technology, the controller 110 sets an indicator that indicates the cell ID information as the location measuring measurement indicator.

The AOA technology is a technology that obtains a direction angle by measuring the direction of the signal transmitted from the terminal by two or more base stations and determines the location of the terminal using the obtained direction angle. In the case of the AOA technology, the controller 110 sets the indicator that indicates the direction angle information as the location measuring parameter indication.

The TOA technology is a technology that measuring the location of the terminal by measuring the time of arrival (TOA) between the terminal and the base station. A circle is geometrically drawn based on the base station, and the terminal 20 is located above the circle. Several circles are generated from values obtained by measuring the time of arrival from a service base station and a neighboring base station. The intersection point is estimated as the location of the terminal 20. In the case of the TOA technology, the controller 110 sets an indicator that indicates the time of arrival information between the terminal and the base station as the location measuring parameter.

The TDOA technology measures the time difference of arrival between the signal from the service base station and the signal from the neighboring base station, and measures the location of the terminal using the measured time difference of arrival. A hyperbolic curve is geometrically drawn based on two base stations using the time difference of arrival of a signal, and the terminal 20 is located above the hyperbolic curve. Several hyperbolic curves are generated from the measuring values of the time difference of arrival of a signal between the service base station and the neighboring base station, and the intersection points of the hyperbolic curves are estimated as the location of the terminal 20. In the case of the TDOA technology, the controller 110 sets the indicator that indicates the time difference of arrival between the signal from the service base station and the signal from the neighboring base station as the location measuring parameter indicator.

The A-GPS technology is a technology in which the GPS receiving apparatus built in the terminal measures signals transmitted from more than three satellites, and measures the location of the terminal using the measured signals. In the case of using the terminal including the GPS receiving apparatus, the controller 110 does not set the indication that indicates the location measuring parameter. That is, even when the controller 110 transmits only the indicator that indicates the A-GPS technology to the apparatus 200 for reporting location information, the apparatus for reporting location information can report the location information necessary for the A-GPS technology.

In addition, in the wireless location measurement technology in addition to the A-GPS technology among the above-mentioned wireless location measurement technologies, the location of the terminal 20 can be estimated using carrier to interface ratio (CINR) information, received signal strength indicator (RSSI) information, round trip delay (RTD) information, relative delay (RD) information, etc., such that the controller 110 can set the indicator that indicates one of them as the location measuring parameter indicator. For example, in the cell-ID technology, the location of the terminal 20 can be estimated based on the RTD information, the RSSI information, and the CINR information, such that the controller 110 can set the indicator that indicates at least one of the RTD information, the RSSI information, and the CINR information in addition to the cell-ID information. The controller 110 can change the wireless location measurement type or the location measuring parameter, and terminates the report of the location information to the apparatus 200 for reporting location information while it receives the location information from the apparatus 200 for reporting location information.

The determining unit 120 determines the final location of the terminal 20 based on the location information reported from the apparatus 200 for reporting location information.

Next, the apparatus 200 for reporting location information includes an information reporting unit 210, a condition confirming unit 220, and a condition updating unit 230.

The information reporting unit 210 collects the location information corresponding to the location measuring parameter, and when it receives the reporting start or reporting request for the location information from the apparatus 100 for determining location, reports the collected location information to the apparatus 100 for determining location and reports the location information collected at the reporting timing of the location information to the apparatus 100 for determining location information until the termination instruction of the report of the location information is issued.

The condition confirming unit 220 sets the reporting condition of the location information, determines the reporting timing of the location information according to the reporting condition, and transmits the reporting timing of the location information to the information reporting unit 210. In order to set the reporting condition of the location information, the condition confirming unit 220 sets a time based on the reporting period received from the apparatus 100 for determining location, and sets an event generating condition within the reporting period. The event generating condition can be set to generate the event when the location variations of the terminal 20 exceed a threshold within the reporting period. For example, the event generating condition can be set to generate the event when a distance between the current location of the terminal 20 and the location of the terminal 20 that finally performs the reporting exceeds the threshold.

The condition confirming unit 220 determines the reporting timing of the location information when the reporting period and the event generating condition are satisfied and transmits the reporting timing of the determined location information to the information reporting unit 210.

The condition updating unit 230 updates the reporting condition of the location information. The reporting condition of the location information can be transmitted from the apparatus 100 for determining location, and can be internally set.

Generally, the terminal 20 in the wireless communication system supports an idle mode to reduce power consumption. In the case of the idle mode, all the connection states between the terminal 20 and the base station 10 are released. On the other hand, in the case of an active mode such as a sleep mode or an awake mode, etc., the connection state between the terminal 20 and the base state 10 is maintained. Therefore, the signaling procedure for reporting the location information between the terminal and the base station that are in the idle mode and the signaling procedure for reporting the location information between the terminal and the base station that are in the active mode are performed differently.

FIG. 3 is a diagram showing a method for reporting location information of the terminal in the active mode according to an exemplary embodiment of the present invention, and FIG. 4 is a diagram showing a method for reporting location information according to the reporting condition of the location information according to an exemplary embodiment of the present invention.

Referring to FIG. 3, the apparatus 100 for determining location transmits a location based service request message (LBS_REQ) to the apparatus 200 for reporting location information of the terminal 20 that is in the active mode to instruct the reporting start or reporting request of the location information (S310). At this time, the location based service request message (LBS_REQ) includes a start information (LBS on) of the location based service, an indicator [LBS type (GPS, BS)] that indicates the information on the wireless location measurement technology, and a reporting period (Update timer). Further, the location based service request message (LBS_REQ) further includes a indicator (Metric) that indicates the location measuring parameter necessary for the corresponding wireless location measurement type when the wireless location measurement type is not the A-GPS technology.

When the wireless local measurement type is the A-GPS [LBS type (GPS)], the location information necessary for the A-GPS technology is set, such that the apparatus 100 for determining location does not include the indicator that indicates the position measuring parameter necessary for the A-GPS technology [LBS type (GPS)] in the location based service request message (LBS_REQ). Unlike this, the apparatus 100 for determining location may include the indicator that indicates the location measuring parameter necessary for the A-GPS technology [LBS type (GPS)] in the location based service request message (LBS_REQ).

The apparatus 200 for reporting location information collects the location information corresponding to the location measuring parameter in response to the location based service request message (LBS_REQ), and transmits the collected location information included in the location based service response message (LBS_REP) to the apparatus 100 for determining location and reports it to the apparatus 100 for determining location (S320).

Then, the apparatus 200 for reporting location information determines whether the reporting condition of the predetermined location information is satisfied (S330), and includes the collected location information in the location based service response message (LBS_REP) and reports it to the apparatus 100 for determining location whenever the reporting condition of the set location information is satisfied (S340).

In detail, referring to FIG. 4, the apparatus 200 for reporting location information reports the location information collected in response to the location based service request message (LBS_REQ) (S410), and then activates a timer based on the reporting period (Update timer) that is included in the location based service request message (LBS_REQ).

When the timer is timed out (S420), the apparatus 200 for reporting location information includes the collected location information in the location based service response message (LBS_REP) and reports it to the apparatus for determining location (S410). Thereafter, the timer is reactivated.

In addition, when the timer is not timed out, the apparatus 200 for reporting location information compares the variations of the location information with the predetermined threshold (S430), and when the variations of the location information exceed the threshold, includes the collected location information in the location based service response message (LBS_REP) and reports it to the apparatus 100 for determining location (S410).

The apparatus 100 for determining location includes an indicator (LBS off), which informs the reporting termination of the location information, in the location based service request message (LBS_REQ), and terminates the report of the location information to the apparatus 200 for reporting location information (S350).

The apparatus 200 for reporting location information performs the above operations and reports the location information to the apparatus 100 for determining location until it receives the instruction of the reporting termination of the location information from the apparatus 100 for determining location.

Meanwhile, the apparatus 100 for determining location can change the location measuring parameter and can change the wireless location measurement technology, while it receives the report of the location information from the apparatus 200 for reporting location information.

FIG. 5 is a diagram showing the method for reporting location information of the changed terminal in the active mode according to an exemplary embodiment of the present invention.

Referring to FIG. 5, when intending to change the indicator (Metric) indicating the location measuring parameter or the indicator [LBS type (GPS, BS)] indicating the wireless location measurement technology, the apparatus 100 for determining location includes the indicator (Metric') that indicates the location measuring parameter or the indicator [LBS type (GPS, BS)] that indicates the wireless location measurement type in the location based service requesting message (LBS_REQ) to inform the change of the location measuring parameter or the wireless location measurement type and request the location information corresponding to the changed location measuring parameter (S510).

Then, the apparatus 200 for reporting location information collects the location information corresponding to the location measuring parameter that is changed and requested by the apparatus 100 for determining location in the same method as the method described in FIG. 3, and includes the collected location information in the location based service response message (LBS_REP) and transmits it to the apparatus 100 for determining location (S520 to S540).

FIG. 6 is a diagram showing the method for reporting location information of the terminal in the idle mode according to another exemplary embodiment of the present invention.

Referring to FIG. 6, the apparatus 100 for determining location transmits mobile paging advertisement (MOB_PAG_ADV) to the apparatus 200 for reporting location information of the terminal 20 that is in the idle mode, and instructs the reporting start or reporting request of the location information (S610). At this time, the mobile paging advertisement (MOB_PAG_ADV) includes the indicator that indicates a start information [action code (LBS on)] of the location information reporting and the indicator [LBS type (GPS, BS)] that indicates the wireless location measurement technology, and the reporting period (Update timer). Furthermore, the mobile paging advertisement (MOB_PAG_ADV) further includes the indicator (Metric) that indicates the location measuring parameter necessary for the corresponding wireless location measurement type when the wireless location measurement type is not the A-GPS technology [LBS type (BS)].

Meanwhile, when the terminal 20, which is in the idle mode, receives the mobile paging advertisement (MOB_PAG_ADV), it performs a re-entry process of the network.

The wireless communication system in the orthogonal frequency division multiple access (OFDMA) technology performs a ranging request and an uplink band request using the CDMA code so that the terminal 20 controls the uplink transmission parameter. In other words, the base station 10 includes the allocated ranging region information (region info) in the mobile paging advertisement (MOB_PAG_ADV) in order to perform the CDMA code set (LBS code set) and authentication for ranging, and transmits the CDMA code set (LBS code set) and the region information (region info) for ranging to the terminal 20.

The terminal 20 arbitrarily selects the ranging code (LBS CDMA code) meeting the usage among the CDMA code set (LBS code set) and transmits it to the base station 10 through the allocated ranging region for ranging, thereby requesting the ranging (S620). For example, when the terminal performs the initial ranging, it selects the specific code among the CDMA code set (LBS code set) for initial ranging and transmits it to the base station 10 through the initial ranging region, thereby requesting the initial ranging. Further, when the terminal performs the periodic ranging, it selects the specific code among the CDMA code sets (LBS code set) for periodic ranging and transmits it to the base station 10 through the periodic ranging region, thereby requesting the periodic ranging.

The base station 10 allocates the ranging region to the terminal 20 through the uplink map information element (CDMA allocation IE) included in the uplink map (UL MAP) (S630). At this time, the terminal can divide it into an initial ranging region, a handover ranging region, a periodic ranging region, and a band request ranging region according to the kind of ranging and allocate it thereto.

When the ranging process between the base station 10 and the terminal 20 completes through this process, the apparatus 200 for reporting location information collects the location information corresponding to the location measuring parameter in response to the mobile paging advertisement (MOB_PAG_ADV), includes the collected location information in the location based service response message (LBS_REP), transmits it to the apparatus for determining location, and reports it to the apparatus 100 for determining location (S640).

Then, the apparatus 200 for reporting location information determines whether the reporting condition of the predetermined location information is satisfied (S650), and includes the collected location information in the location based service response message (LBS_REP) and reports it to the apparatus 100 for determining location whenever the reporting condition of the set location information is satisfied (S680).

At this time, after performing the ranging process between the base station 10 and the terminal 20 (S660 and S670), the apparatus 200 for reporting location information can transmit the location based service response message(LBS_REP) to the apparatus 100 for determining location.

The apparatus 100 for determining location includes the indicator (LBS off), which informs the reporting termination of location information, in the mobile paging advertisement message (MOB_PAG_ADV), and terminates the report of the location information to the apparatus 200 for reporting location information (S690).

The apparatus 200 for reporting location information performs the above operations until it receives the instruction of the reporting termination of the location information from the apparatus 100 for determining location, thereby reporting the location information to the apparatus 100 for determining location.

The apparatus 100 for determining location can change the location measuring parameter and the wireless location measurement type while it receives the report of the location information from the apparatus 200 for reporting location information.

FIG. 7 is a diagram showing the method for reporting location information of the changed terminal in the idle mode according to an exemplary embodiment of the present invention.

Referring to FIG. 7, when intending to change the indicator (Metric) that indicates the location measuring parameter or the indicator [LBS type (GPS, BS)] indicating the wireless location measurement technology, the apparatus 100 for determining location includes the indicator (Metric') that indicates the location measuring parameter or the indicator [LBS type (GPS, BS)] that indicates the wireless location measurement type in the mobile paging advertisement message (MOB_PAG_ADV) to inform the change of the location measuring parameter or the wireless location measurement type and request the location information corresponding to the changed location measuring parameter (S710).

Then, the apparatus 200 for reporting location information collects the location information corresponding to the location measuring parameter that is changed and requested by the apparatus 100 for determining location in the same method as the method described in FIG. 6, and includes the collected location information in the location based service response message (LBS_REP) and transmits it to the apparatus 100 for determining location (S720 to S780).
