Abstract

PROBLEM TO BE SOLVED: To allow the position of a terminal device to be found without increasing network traffic in a positioning system for positioning the position of the terminal device designated by a positioning request even when there are a plurality of positioning methods (processing procedures) according to terminal type.SOLUTION: Identification information of terminal devices and identification information of positioning devices succeeded in positioning processing including information exchange between themselves and the terminal devices are associated with each other and are stored in a management table 13. Upon input of a positioning request designating a terminal device as a positioning target, an allocation means 11 in a positioning gateway device 1 retrieves the management table 13. When the identification information of the positioning device are stored in association with the identification information of the designated terminal device, the allocation means 11 allocates the position request to the positioning device indicated by the identification information thereof. When the identification information of the positioning device are not stored so, the allocation means 11 allocates the positioning request to all the positioning devices 2 and 3.

Description

  The present invention relates to a service providing system that provides a service requested to a service requester, and particularly to a service that requires communication with a terminal device specified by the service request. The present invention relates to a service providing system to be provided.

  As a service providing system that needs to communicate with a terminal device such as a portable terminal device specified by the service request in order to provide a service to the service requester, the terminal owner who owns the terminal device A positioning system for knowing the position is known (see, for example, Patent Document 1).

  Referring to FIG. 8, the positioning system described in Patent Document 1 is a positioning gateway device 100 having a management table 110, terminal devices 120 and 121 that are requesting positioning requests, a positioning device 130, and a positioning target. The terminal device 140 is configured.

  When the user of the terminal device 120 wants to know the position of the terminal device 140, the terminal device 120 transmits a positioning request specifying the terminal device 140 to the positioning gateway device 100. Thereby, the positioning gateway device 100 searches the management table 110 and checks whether or not the positioning request information for which the positioning target is the terminal device 140 is recorded. Now, for example, if such positioning request information is not recorded, the positioning gateway device 100 records positioning request information in the management table 110 with the positioning target as the terminal device 140 and the positioning request source as the terminal device 120. At the same time, the positioning request is transmitted to the positioning device 130.

  Thereafter, when a positioning request specifying the terminal device 140 is sent from another terminal device 121 before the positioning result is returned from the positioning device 130, the positioning gateway device 100 stores the positioning target in the management table 110. It is checked whether positioning request information for the device 140 is recorded. In the case of this example, such positioning request information is recorded in the management table 110. Therefore, the positioning gateway device 100 manages the positioning request information with the positioning target as the terminal device 140 and the positioning request source as the terminal device 121. Only the process of recording in 110 is performed, and the process of transmitting a positioning request to the positioning device 130 is not performed.

  On the other hand, when a positioning request specifying the terminal device 140 is passed from the positioning gateway device 100, the positioning device 130 communicates with the terminal device 140 to measure the position, and returns the positioning result to the positioning gateway device 100. Here, the position of the terminal device 140 is obtained as follows, for example. The terminal device 140 is provided with a GPS (Global Positioning System) receiving device and a communication device. The positioning device 130 transmits a positioning request to the terminal device 140.When the terminal device 140 receives the positioning request from the positioning device 130 via the communication device, the position acquired by the GPS receiving device To the positioning gateway device 100.

  When the positioning gateway device 100 receives a positioning result indicating the position of the terminal device 140 from the positioning device 130, the positioning gateway device 100 searches the management table 110 for positioning request information for which the positioning target is the terminal device 140. The positioning result is transmitted to the request source indicated by the positioning request information. In this example, the positioning result is transmitted to the terminal devices 120 and 121.

JP 2005-269679 A

  According to the technique described in Patent Document 1, a positioning request that has not been processed in the positioning gateway device 100 can be used as a positioning request for another same terminal device. Traffic on the network between the target terminal device 140 and the network between the positioning gateway device 100 and the positioning device 130 can be reduced.

  However, although the technique described in Patent Document 1 assumes that there are a plurality of terminal devices that request positioning requests (service request sources), the terminal device specified by the service request is serviced. It is not assumed that there are a plurality of processing procedures (methods) to be performed in accordance with the type of terminal device (model name, model number, etc.). For example, it is not assumed that there are a plurality of protocols between a terminal device to be positioned and a positioning device depending on the type of the terminal device.

  In an environment where the type (model name, model number, etc.) of the terminal device to be positioned is managed, the terminal device positioning method is determined based on this, and the terminal device using the corresponding positioning method positioning device is used. The position of the device can be determined. However, since the type of the terminal device may be changed at any time by changing the terminal model or replacing the SIM (Subscriber Identification Module), it is difficult to centrally manage this. In addition, it is thought that it will be difficult to further manage the terminal type by making SIM-free and the like in the future.

  If the type of terminal device is not managed, there is no problem if there is only one type of positioning method (positioning method A) as shown in FIG. 8, but multiple types of positioning with different processing procedures as shown in FIG. When the method exists, the following problems arise. In FIG. 9, the positioning device 130 and the terminal device 140 correspond to the positioning method A, and the positioning device 131 and the terminal device 141 correspond to the positioning method B.

  Now, for example, it is assumed that the terminal device 120 transmits a positioning request specifying the terminal device 141 as a positioning target to the positioning gateway device 100. Since the positioning gateway device 100 does not know the positioning method of the terminal device 141, the positioning gateway device 100 passes a positioning request to both the positioning device 130 of the positioning method A and the positioning device B of the positioning method B, or until the positioning is successful. A positioning request is passed to the positioning devices of each positioning method in turn. In this case, since a plurality of traffics are generated for one positioning request (service request), a network between the positioning devices 130 and 131 and the terminal devices 140 and 141, or between the positioning gateway device 100 and the positioning devices 130 and 131 are used. The problem of incurring an increase in network traffic occurs. Further, when the network is an external facility, there arises a problem that the cost of use increases.

Referring to FIG. 1, the present embodiment is a positioning gateway device 1, positioning devices 2 and 3, terminal devices 4 and 5 such as a personal computer that is a request source of a positioning request, and a portable terminal device that is a positioning target. Terminal devices 6 and 7.

  The terminal devices 4 and 5 which are requesters of positioning requests are provided with request transmission means 41 and 51 and response reception means 42 and 52, respectively. The request sending means 41 and 51 accept identification information of terminal information to be positioned, which is input by a user from an input unit (not shown) such as a keyboard, and sends a positioning request including the identification information to the positioning gateway device 1. It has a function to transmit. In addition, a telephone number, a user terminal number, IMSI (International Mobile Subscriber Identity) etc. can be used as identification information. The response receiving means 42 and 52 have a function of receiving the positioning result sent from the positioning gateway device 1 and displaying the position information of the terminal device on a display unit such as an LCD. In FIG. 1, the number of terminal devices that are requesting positioning requests is two, but this is not a limitation.

  The positioning devices 2 and 3 correspond to the positioning methods A and B, respectively, and the positioning request sent from the positioning gateway device 1 is measured via a mobile phone network such as 3G or a wireless network such as a wireless LAN. It has a function to transmit to the target terminal device. Further, the positioning devices 2 and 3 have a function of transmitting the positioning result sent from the terminal device to be positioned to the positioning gateway device 1. In FIG. 1, two types of positioning methods are provided and one positioning device is provided for each positioning method. However, three or more types of positioning methods are provided, and one positioning device is provided for each positioning method. You may make it provide.

  The terminal devices 6 and 7 to be positioned correspond to the positioning methods A and B, respectively. And when the positioning request | requirement is sent from the positioning apparatus of the positioning system corresponding to the own terminal device 6 and 7, it calculates | requires the positional information of the own terminal device using GPS etc., and uses it as a positioning result, and positioning device Return to. On the other hand, if a positioning request is sent from a positioning device that does not correspond to the own terminal device 6 or 7, the received positioning request is ignored and discarded, or the positioning result is NG. Notify (abnormal termination). In the present embodiment, the difference between the positioning methods A and B is the protocol between the terminal device and the positioning device, and the terminal devices 6 and 7 receive positioning requests from positioning devices that do not support the positioning method. Will be ignored and discarded.

  The positioning gateway device 1 includes a distribution unit 11, a response unit 12, and a management table 13.

  In the management table 13, the identification information of the terminal device and the identification information of the positioning device that has succeeded in positioning the terminal device are recorded in association with each other.

A disk, a semiconductor memory, and other recording media recording a program for causing a computer to function as the positioning gateway device 1 are prepared, and the computer reads the program. The computer realizes the distribution means 11 and the response means 12 on its own computer by controlling its own operation according to the read program.

[Description of Operation of First Embodiment]
Next, the operation of the present embodiment will be described in detail with reference to the drawings.

  First, the operation of the positioning gateway device 1 will be described with reference to the flowchart of FIG.

  When receiving the positioning request from the terminal devices 4 and 5, the distribution means 11 in the positioning gateway device 1 searches the management table 13 for identification information of the terminal device designated as a positioning target by the positioning request ( Step S31).

  If the identification information of the terminal device to be positioned can be retrieved (YES in step S32), the positioning successfully recorded in the past is recorded in association with the retrieved identification information of the terminal device. The device identification information is input, and a positioning request is transmitted to the positioning device indicated by the identification information (step S33).

  Thereafter, when a positioning result including the position information of the terminal device is sent from the positioning device (YES in step S34), the response means 12 in the positioning gateway device 1 performs positioning with respect to the requesting terminal device. The result is transmitted (step S35), and the process ends.

  On the other hand, when a positioning result indicating a positioning failure (NG) is sent from the positioning device (NO in step S34), the distribution means 11 is the positioning device 2 connected to the positioning gateway device 1. 3, the positioning request is transmitted to positioning devices other than the positioning device that has transmitted the positioning request this time (step S <b> 37).

  Thereafter, when a positioning result including the position information of the terminal device is sent from the positioning device (YES in step S38), the response means 12 sends the identification information of the terminal device that is the positioning target this time and the positioning result. The management table 13 is updated so as to be recorded in association with the identification information of the source positioning device (step S39), and then the positioning result is transmitted to the requesting terminal device (step S35).

  On the other hand, even if a predetermined time elapses after the distribution means 11 transmits a positioning request to the positioning device, a positioning result including the position information of the positioning target is sent from the positioning device. If not received (NO in step S38), the response unit 12 transmits a positioning result indicating a positioning failure to the requesting terminal device (step S40), and thereafter ends the processing.

  In step S31, when the identification information of the terminal device to be positioned cannot be searched (NO in step S32), the distribution unit 11 is connected to all the positioning devices 2 and 3 connected to the positioning gateway device 1. A positioning request is transmitted to (step S36). When the positioning result including the position information of the positioning target is sent from the positioning device (YES in step S38), the processing in steps S39 and S35 described above is performed, and the positioning result indicating the positioning failure is sent. If this is the case (NO in step S38), the process of step S40 described above is performed.

  Next, the operation of the present embodiment will be described with a specific example.

(Operation at the time of the first positioning request)
First, the operation when the first (first) positioning request targeting the terminal device 6 is transmitted from the terminal device 4 to the positioning gateway device 1 will be described (see FIGS. 4 and 5).

  When a positioning request specifying the terminal device 6 as the positioning target is sent from the terminal device 4 (see FIG. 4), the distribution means 11 in the positioning gateway device 1 identifies the positioning target terminal device 6 from the management table 13. Information (user terminal number, telephone number, IMSI, etc.) is searched (step S31 in FIG. 3). If the identification information of the terminal device 6 cannot be retrieved because it is a newly joined terminal or the like (step S32 is NO), the distribution unit 11 transmits a positioning request to all the positioning devices 2 and 3 ( Step S36). Here, the distribution unit 11 may transmit the positioning request to all the positioning devices 2 and 3 at the same time, or may sequentially transmit the positioning request to each positioning device 2 and 3. .

  When the positioning devices 2 and 3 receive a positioning request in which the terminal device 6 is designated as a positioning target, the positioning devices 2 and 3 each execute a process (service providing process) for acquiring the position information of the terminal device 6. In the present embodiment, the positioning devices 2 and 3 correspond to the positioning methods A and B, respectively, and the processing procedure of the service providing process to be executed is different (for example, in the positioning methods A and B, from the terminal device). The communication protocol for acquiring location information is different). On the other hand, the terminal device 6 to be positioned corresponds to the positioning method A. Therefore, as shown in FIG. 5, the positioning device 2 corresponding to the positioning method A can normally communicate with the terminal device 6 and receive the positioning result including the position information of the terminal device 6. The positioning device 3 corresponding to B cannot normally communicate with the terminal device 6 and cannot receive the positioning result including the position information of the terminal device 6. The positioning device 2 that has received the positioning result including the position information of the terminal device 6 transmits it to the positioning gateway device 1.

  The response means 12 in the positioning gateway device 1 receives the positioning result including the position information of the terminal device 6 from the positioning device 2 (YES in step S38), and the identification information of the terminal device 6 and the positioning device 2 The identification information is associated and recorded in the management table 13, and the positioning result is transmitted to the requesting terminal device 4 (steps S39 and S35), and then the processing is terminated.

(Operation at the time of positioning request after the second)
Next, the operation when the terminal device 5 transmits a positioning request after the second time specifying the terminal device 6 as a positioning target to the positioning gateway device 1 will be described (see FIG. 6).

  The distribution means 11 in the positioning gateway device 1 retrieves the identification information of the terminal device 6 from the management table 13 when a positioning request specifying the terminal device 6 as a positioning target is sent from the terminal device 5 (see FIG. 6). (Step S31 in FIG. 3). Since the management table 13 records the identification information of the terminal device 6 and the identification information of the positioning device 2 that has succeeded in the positioning of the terminal device 6 when the positioning of the terminal device 6 was successful in the past. The distribution means 11 transmits a positioning request only to the positioning device 2 (YES in step S32, S33). As described above, since both the terminal device 6 and the positioning device 2 are compatible with the positioning method A, the positioning is successful and the positioning result is sent to the requesting terminal device 4 (YES in step S34, S35). .

(Operation when there is a model change)
Next, the operation when the owner of the terminal device 6 changes the model after the second and subsequent positioning requests specifying the terminal device 6 as a positioning target will be described (see FIG. 7).

  It is assumed that the owner of the terminal device 6 has changed the model by replacing the SIM. In FIG. 7, the terminal device after the model change is a terminal device 6a. The identification information of the terminal device 6a after the model change is the same as that of the terminal device 6 before the model change. Further, the positioning method of the terminal device 6a is the positioning method B, which is different from the positioning method A of the terminal device 6 before the model change.

  The distribution means 11 in the positioning gateway device 1 receives a positioning request (terminal device 6a) including identification information (user terminal number, IMIS, telephone number, etc.) of the terminal device 6a from the terminal device 5 after the model change. When the positioning request is sent as a positioning target, the identification information of the terminal device 6a is searched from the management table 13 (step S31 in FIG. 3). Since the management table 13 records the identification information of the positioning device 2 in association with the identification information of the terminal device 6 (same as the identification information of the terminal device 6a), the distribution means 11 sends a positioning request to the positioning device 2. (Step S32 in FIG. 3 is YES, S33).

  The positioning device 2 communicates with the terminal device 6a and attempts to receive a positioning result including the position information of the terminal device 6a. The positioning method of the terminal device 6a is the positioning method B, and the positioning method of the positioning device 2 Since it is different from A, the positioning result including the position information of the terminal device 6a cannot be received. Further, the response means 12 in the positioning gateway device 1 cannot receive the positioning result including the position information of the terminal device 6a.

  The response means 12 in the positioning gateway device 1 is the terminal device 6a even if a predetermined time elapses after the distribution means 11 transmits a positioning request specifying the terminal device 6a to the positioning device 2. Since the positioning result including the position information cannot be received, it is determined that the positioning has failed (step S34 is NO), and other positioning devices (the positioning device 3 in this example) excluding the positioning device 2 are A positioning request including the identification information of the terminal device 6a is transmitted (step S37).

  Since the positioning device 3 corresponds to the positioning method B, and the terminal device 6a after the model change also corresponds to the positioning method B, communication is normally performed between the two, and the positioning device 3 is connected to the terminal device 6a. The positioning result including the position information is received, and the received positioning result is transmitted to the positioning gateway device 1.

  When the response means 12 in the positioning gateway device 1 receives the positioning result including the position information of the terminal device 6a from the positioning device 3, it determines that the positioning is successful (step S38 is YES) and is designated by the positioning request. The management table 13 is updated so that the identification information of the terminal device 6a and the identification information of the positioning device 3 that has been successfully positioned are recorded in association with each other (step S39). That is, the identification information of the positioning device 2 recorded in association with the identification information of the terminal device 6a is changed to the identification information of the positioning device 3 that has succeeded in positioning. Thereafter, the response means 12 transmits a positioning result including the position information of the terminal device 6a to the terminal device 5 (step S35), and thereafter ends the processing.

[Effect of the first embodiment]
According to the present embodiment, even if there are a plurality of processing procedures for the terminal device type specified by the positioning request (service request) to provide the service, the network traffic It is possible to inform the request source of the positioning request of the position of the terminal device without increasing the value. The reason for this is that it includes a management table 13 in which identification information of a terminal device and identification information of a positioning device that has succeeded in processing including information exchange with the terminal device are recorded in association with each other, and a positioning request is made by a positioning request. When the identification information of the terminal device designated to be recorded is recorded in the management table 13, the distribution unit 11 distributes the positioning request to the positioning device in which the identification information is recorded in association therewith. Because.

  In addition, according to the present embodiment, when the owner of the terminal device to be positioned changes the model by SIM exchange or the like, the contents of the management table 13 are automatically updated without the intervention of the user or operator. It can be changed according to the model after the change. The reason is that if positioning fails in the positioning device that distributes the positioning request based on the contents of the management table 13, the distributing means 11 distributes the positioning request to the remaining positioning devices, and a positioning device that succeeds in positioning occurs. In this case, the response means 12 updates the contents of the management table 13 so that the identification information of the terminal device specified by the positioning request and the identification information of the positioning device that has succeeded in positioning are recorded in association with each other. It is.
