Abstract

<P>PROBLEM TO BE SOLVED: To respond to all positioning requests in a short time by confirming a user's intention about notifying the third person of positional information when there are positioning requests simultaneously from a plurality of users. <P>SOLUTION: When receiving a positioning request from the third person during the execution of user positioning by self-starting (steps S2, S3) or receiving a positioning request from the different third person during the execution of positioning at the positioning request from the third person, positioning is not started on a mobile unit executing user positioning when further receiving a positioning request, but only the confirmation of the user's intention as to notification to the third person of positional information is carried out in parallel with positioning (steps S4-S9). Only when the intention confirmed result is "permitting position notification" at a point of time when the result of already started positioning is obtained, the same positioning result as the obtained positioning result is given to the positioning request received afterwards (step S14). <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  In the field of position information search system from a third party, the present invention provides a user at the time of multiple simultaneous positioning requests to change the positioning result in a short time while ensuring user privacy when multiple positioning activations overlap. The present invention relates to a privacy authentication system and a user privacy authentication method.

  The location information of the mobile device is important privacy information for the user who uses the mobile device because it is not known where the mobile device is currently located. For this reason, mobile communication networks are required to have advanced privacy protection functions that prevent unauthorized acquisition of location information and restrict access to location information based on time, location, etc. in response to requests from mobile users. It is becoming. Privacy protection functions include those that can be determined at the time of positioning request reception, such as registering clients and services that accept positioning requests, and those that allow positioning only at specific locations and time zones. There are things that can only be judged. In particular, when there are positioning requests from a plurality of users at the same time, an advanced privacy authentication method for protecting the privacy of the users becomes necessary.

On the other hand, in order to provide a location information service, a mobile communication network operator needs to measure the location of a mobile device. For this reason, it is necessary to send and receive messages between nodes in the network.
In particular, in externally activated positioning, when the client apparatus requests the position of the UE apparatus and the network returns the position of the UE apparatus to the client, the positioning process is always executed in the SGSN / MSC apparatus. When positioning requests increase, positioning traffic and positioning processing load increase proportionally, which may hinder the network operation of the mobile carrier, so past positioning held by the SGSN / MSC device The reuse of results is not very effective for the purpose of reducing the positioning traffic and the positioning processing load.

  As an example of the above-described conventional example, for example, Patent Document 1 describes that past positioning results can be reused and that user privacy is protected even when positioning results are reused. In the present invention, when a client requests positioning of a mobile device from GMLC (Gateway Mobile Location Center), GMLC refers to the privacy setting information of the mobile device, confirms the positioning request, and positioning is not prohibited. When the past position is acceptable, the GMLC confirms whether or not the positioning result of the held mobile device can be reused, and if it is reusable and the mobile device needs to be notified, the GMLC performs MSC (Mobile Service). This is a system that sends a privacy-related message to a mobile device via a switching center and receives a privacy confirmation result.

Patent Document 2 describes a system in which a mobile terminal can improve economy and suppress power consumption in a positioning system in which a mobile terminal transmits positioning data to a positioning server. In the present invention, the mobile terminal compares the position of the own terminal indicated based on the positioning data acquired by the GPS positioning unit with the position of the own terminal indicated based on the past positioning data. In this case, the system transmits the data acquired by the GPS positioning unit to the positioning server.

However, both of the inventions described in Patent Documents 1 and 2 cannot confirm the user's intention regarding notification of position information to a third party. If there is a positioning request, the positioning activation and privacy authentication are performed each time. When positioning requests were received from the same user from multiple searchers at the same time, it was not possible to efficiently notify the searchers in a short time while ensuring user privacy. .
The present invention has been made in view of the above-described circumstances, and by confirming the user's intention regarding notifying position information to a third party when there are positioning requests from a plurality of users at the same time. An object of the present invention is to provide a privacy authentication system that can respond to all positioning requests in a short time.

  In order to solve the above-mentioned problem, the privacy authentication system according to claim 1 measures the position of a user and acquires position information based on information such as a signal from a GPS (Global Positioning System) or a mobile phone base station. A positioning system for managing a positioning state of a user in a user privacy authentication system for ensuring user privacy when a positioning request is simultaneously received from a plurality of searchers for the same user. Management means, positioning request accepting means for accepting a positioning request from each searcher to the user, and confirmation of intention regarding confirmation of notification of location information to the third party of the user in response to a subsequent positioning request Means, positioning result management means for managing positioning results of the user, and the intention confirmation means And positioning result return means for returning the positioning result of the user in response to a plurality of positioning requests.

According to this configuration, the positioning request to the user is accepted, the user's intention is confirmed for the subsequent positioning request, and only the positioning result that has been started first is used as the positioning result, so the time is short. With this, it is possible to effectively notify the positioning result.
According to this configuration, since the user's intention confirmation regarding notifying the location information to the third party is performed, it is possible to effectively notify the positioning result in a short time while ensuring privacy.

The invention according to claim 2 relates to the user privacy authentication system at the time of multiple simultaneous positioning requests according to claim 1, and when positioning request is received from a third party during self-starting user positioning, positioning is performed. Only the user's intention confirmation regarding notifying the location information to a third party without starting up is performed in parallel with the positioning, and when the positioning result that has already been started is obtained, the intention confirmation result is `` Allow location notification '' Only in the case of, the same positioning result as that obtained for a positioning request received from a third party is notified.
According to this configuration, when a positioning request is received from a third party while performing user positioning by self-activation, the user's intention confirmation regarding notifying positioning information to the third party is performed without starting positioning. As a result, it is possible to effectively notify the positioning result in a short time while ensuring privacy.

Further, the invention described in claim 3 relates to the user privacy authentication system at the time of the multiple simultaneous positioning request described in claim 1, and accepts a positioning request from a different third party during the user positioning by the positioning request from the third party. In this case, only the user's intention confirmation regarding notifying the location information to the third party without starting the positioning is performed in parallel with the positioning, and the confirmation result is obtained when the positioning result is already started. Only when “Position notification is permitted”, the same positioning result as that obtained for a positioning request received later is returned.
According to this configuration, when a positioning request is received from a different third party while a user positioning is being performed due to a positioning request from a third party, positioning is not activated and the user is informed of the location information to the third party. Therefore, it is possible to effectively notify the positioning result in a short time while ensuring privacy.

The invention described in claim 4 relates to the user privacy authentication system in the multiple simultaneous positioning request described in claim 2 or 3, and manages the positioning status of the user, and from other third parties during the user positioning. When the positioning request is received, the user's intention confirmation regarding notifying the location information to the third party is activated, and the positioning request is accepted only when the intention confirmation result is “Position notification allowed”. In contrast, the same positioning result as the positioning result obtained for the already running positioning is returned.
According to this configuration, when a positioning request is received, the intention confirmation regarding notifying the location information to a third party is activated, so that the positioning result can be notified efficiently in a short time while ensuring privacy. An effect is obtained.

Further, the user privacy authentication method according to claim 5 is a service for measuring the position of the user and acquiring the position information based on information such as a signal from a GPS (Global Positioning System) or a mobile phone base station, In a user privacy authentication method for ensuring the privacy of a user when receiving a positioning request for the same user simultaneously from a plurality of searchers, a positioning state management step for managing the positioning state of the user, A positioning request receiving step for receiving a positioning request from the searcher to the user, an intention confirmation step for confirming the intention of notifying the user of the location information in response to a subsequent positioning request, Based on a positioning result management step for managing positioning results and the intention confirmation step. Returning a positioning result of the user to a plurality of positioning requests, and when a positioning request is received from a third party during self-starting user positioning, or a positioning request from a third party. When a positioning request is received from a different third party while positioning is being performed, positioning is not started when a positioning request is further received for a mobile device that is performing user positioning. Only when the user's intention confirmation regarding notifying the location information is performed in parallel with the positioning, and the positioning confirmation result is already `` Position Notification Allowed '' at the time when the positioning result is already active, The same positioning result as that obtained for a positioning request received later is notified.
According to this configuration, the positioning request to the user is accepted, the user's intention is confirmed for the subsequent positioning request, and only the positioning result that has been started first is used as the positioning result, so the time is short. With this, it is possible to effectively notify the positioning result.

  By applying the present invention, when a positioning request is received from a plurality of searchers to the same user at the same time, positioning is not started individually, but positioning already started is executed as it is. In response to the positioning request, only the user's intention confirmation regarding notifying the location information to the third party is performed, and the positioning result is obtained by using only the positioning result activated first. While securing, it is possible to notify the searcher of the positioning result in a short time.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of a user privacy authentication system according to an embodiment of the present invention.
As shown in the figure, the privacy authentication system 10 of the present invention includes a positioning state management means 11, a positioning request reception means 12, a user intention confirmation means 13, a positioning result management means 14, and a positioning result return means 15. Is provided. The positioning state management unit 11 manages the positioning state of the user, and the positioning request receiving unit 12 receives a positioning request from each searcher to the user, and determines whether or not the user's positioning related to the positioning request is being performed. To do. The intention confirmation means 13 confirms the user's intention regarding notifying the third party of the position information in response to the subsequent positioning request. The positioning result management means 14 manages the positioning result of the user. The positioning result returning means 15 returns the positioning result of the user in response to a plurality of positioning requests based on the intention confirmation means 13.

  With the above configuration, this system 10 measures the position of a user based on information such as a signal from a GPS (Global Positioning System) or a mobile phone base station in a position information search system from a third party, and obtains position information. In the positioning system to be acquired, when a positioning request is simultaneously received from a plurality of searchers to the same user, the positioning result is used in a short time while ensuring the privacy of the user.

In the present embodiment, each component is mainly arranged in the GMLC device or the MSC device, but it goes without saying that it can be arranged in another device.
2 and 3 are schematic diagrams showing the overall configuration and operation of a communication system applied to the user privacy authentication system according to the embodiment of the present invention. FIG. 2 shows a response method to a third party positioning request during self-initiated positioning, and FIG. 3 shows a response method to a different third party positioning request during a third party positioning request.

  As shown in FIGS. 2 and 3, the communication system applied to this system is a mobile device UE (User Equipment) 1 used by a user and an ASP (Application Service) that is a service provider that makes a positioning request to the mobile device UE1. Provider) 2, a GMLC (Gateway Mobile Location Center) device 3 that manages positioning requests from the ASP 2, a RAN (Radio Access Network) device 5 that is a regional wireless network, and a node that manages the regional wireless network RAN device 5. A certain MSC / SGSN (Mobile Service switching Center / Serving General packet radio service Support Node) device 4 Consists of Although there are a plurality of service providers ASP2, in the drawing, the service providers ASP2 are displayed as distinguished from the first service provider ASP2a and the second service provider ASP2b.

[Response method to a third-party positioning request during self-starting positioning]
First, when a positioning request is received from a third party while user positioning is being performed by self-activation, only the user's intention confirmation is performed in parallel with the positioning with respect to notifying positioning to the third party without starting positioning. This is the same as the positioning result obtained for a positioning request received from a third party only if the intention result is `` Position Notification Allowed '' when the positioning result that has already been started is obtained. Notify the positioning result of.

  That is, with reference to FIG. 2, positioning by self-activation is being performed between the MSC / SGSN device 4 that manages the positioning state of the mobile device UE1 and the mobile device UE1 (step S1). At that time, when a positioning request is made from the second service provider ASP2b to the MSC / SGSN device 4 via the GMLC device 3 (steps S2 and S3), the MSC / SGSN device 4 communicates with the mobile device UE1. It is recognized that positioning is being performed (step S4). Then, a privacy authentication request is made from the MSC / SGSN device 4 to the mobile device UE1 (step S5). At that time, MSISDN (Mobile Station International PSTN / ISDN Number), searcher name, etc. are simultaneously transmitted as privacy information. The mobile device UE1 that has received the privacy authentication request recognizes that it is a positioning request from the second provider ASP2b different from the provider ASP that is currently performing positioning (step S6). Then, one of “positioning permission / non-permission” setting indicating whether or not to permit positioning result notification is selected (step S7), and the MSC / SGSN device 4 is notified as a privacy authentication response (step S8). . At that time, “MSISDN, searcher name, positioning permission / non-permission” is transmitted simultaneously. Then, after receiving the privacy authentication response, the MSC / SGSN device 4 performs a privacy authentication determination (step S9), and if “non-permitted” is selected from “positioning permitted / unpermitted”, the second The service provider ASP2b is notified of the positioning result “authentication NG” (step S10). If “positioning permission” is selected from “positioning permission / non-permission”, the mobile device UE1 makes a self-started positioning request. A positioning result based on the received position is received (step S11). At this time, the same applies when searching for the self-location without notifying the first service provider ASP2a of the location information, but the positioning result notification signal to the first service provider ASP2a is unnecessary. Thereafter, the MSC / SGSN device 4 notifies the first service provider ASP 2a of the positioning result as position information (step S12). Next, the same positioning result is mapped in the MSC / SGSN device 4 (step S13). Finally, the positioning result (position information) is notified from the MSC / SGSN device 4 to the second service provider ASP 2b (step S14).

[Response method to different third-party positioning requests during third-party positioning requests]
Next, when a positioning request is received from a different third party while a user positioning is being performed by a positioning request from a third party, the user's intention confirmation regarding notifying positioning information to the third party without starting positioning Only when the positioning confirmation result is “Position Notification Allowed” at the time when the positioning result is already activated and the positioning confirmation result is “Position Notification Allowed”, it was obtained for the positioning request received later. Returns the same positioning result as the result.

  That is, with reference to FIG. 3, positioning based on the positioning request of the first service provider ASP2a is being performed between the first service provider ASP2a and the mobile device UE1 (step S21). At that time, when a positioning request is made from the second service provider ASP2b to the GMLC device 3 that manages the positioning request from the service provider ASP (step S22), the GMLC device 3 is connected to the first service provider ASP2a. Recognizing that the mobile device UE1 is performing positioning (step S23). Then, the GMLC device 3 makes a privacy authentication request to the mobile device UE1 via the MSC / SGSN device 4 (steps S24 and S25). At that time, MSISDN (Mobile Station International PSTN / ISDN Number), searcher name, etc. are transmitted simultaneously. The mobile device UE1 that has received the privacy authentication request recognizes that it is a positioning request from the second service provider ASP2b different from the provider ASP that is currently performing positioning (step S26). Then, any one of “positioning permission / non-permission” setting indicating whether or not to permit positioning result notification is selected (step S27), and a privacy authentication response is sent to the GMLC device 3 via the MSC / SGSN device 4. Notification is made (steps S28 and S29). At that time, “MSISDN, searcher name, positioning permission / non-permission” is transmitted simultaneously. Then, after receiving the privacy authentication response, the GMLC device 3 performs a privacy authentication determination (step S30). If “non-permitted” is selected from “positioning permission / non-permission”, the second service is determined. The provider ASP2b is notified of the positioning result “authentication NG” (step S31), and if permission is selected from “positioning permission / non-permission”, the mobile device UE1 is based on the positioning request of the first service provider ASP2a. The positioning result is received (step S32), and the positioning result is notified as position information to the first service provider ASP2a (step S33). Next, the same positioning result is mapped in the GMLC apparatus 3 (step S34). Finally, the positioning result (position information) is notified from the GMLC device 3 to the second service provider ASP 2b (step S35).

As described above, by applying this embodiment, when a positioning request is received from a plurality of searchers at the same time for the same user, the positioning result is not first activated but the positioning result is first. Use only the positioning results that have been activated. Therefore, even when a plurality of positioning requests are received simultaneously, it is possible to respond to all positioning requests efficiently in a short time.
In addition, the response method to a third-party positioning request during self-initiated positioning and the response method to a different third-party positioning request during a third-party positioning request have been described separately. Can also be applied.

[Response method to third-party positioning request after completion of positioning]
In the above-described embodiment, the operation when a positioning request is received from a third party during positioning is described, but the positioning result is held for a certain period after the positioning is completed, and the positioning request received within the holding period is On the other hand, the positioning result obtained previously can also be transmitted. In this case, this positioning result is held in the positioning result management means 14 for a certain period. The holding period can be set arbitrarily, but it is necessary to set the holding period range to such an extent that the positioning accuracy is not affected. Then, the positioning result held by the positioning result return means 15 is transmitted based on the result of confirmation by the intention confirmation means 13.

  By applying this embodiment, when a positioning request is received from a plurality of searchers to the same user at the same time, since the positioning result is retained for a certain period, the positioning result already obtained is transmitted. Therefore, even when a plurality of positioning requests are received simultaneously, it becomes possible to respond to all positioning requests more efficiently in a shorter time.

As mentioned above, although embodiment of this invention was described, this invention is not limited to this, A various change is possible in the range which does not deviate from the meaning of this invention.
For example, in the above-described embodiment, a mobile phone device is used as a mobile device (UE), but the present invention is not limited to this, and can be applied to any mobile phone such as a phone that can be mounted on a car phone, a train, an airplane, a ship, etc. Needless to say.
In the above-described embodiment, MSISDN, searcher name, and the like are used as privacy information. However, the present invention is not limited to this, and privacy information using other symbols, numerical values, and the like can also be used.
