The functions of the decoding section 41 and the data transmitting section 42 are realized by the above-mentioned hardware working together in the service provider server device 40.

In the communication carrier server device 30, the authentication unit 31 performs authentication processing to authenticate the user of the wireless terminal 10 requesting connection to the wireless LAN 2. This authentication process is performed, for example, by comparing authentication information such as an ID and password assigned to each user with pre-stored information.

In the carrier server device 30, the acquisition unit 32 acquires user information regarding the user authenticated by the authentication unit 31. More specifically, the acquisition unit 32 acquires user information of a type corresponding to the service provider server device 40 specified by the user among the plurality of service provider server devices 40.

[motion]
Next, the operation of the wireless communication system 1 will be explained with reference to FIGS. 4 to 6. In the following explanation, when the carrier server device 30 is described as the subject of processing, specifically, by loading predetermined software (program) onto hardware such as the processor 3001 and memory 3002. , means that processing is executed by the processor 3001 performing calculations and controlling communication by the communication device 3004 and reading and/or writing of data in the memory 3002 and storage 3003. The same applies to the wireless terminal 10 and the service provider server device 40.

In FIG. 4, the user operates the wireless terminal 10 to display a list of available SSIDs and designates one of them. In response to this operation, the wireless terminal 10 transmits a request for connection to the wireless LAN 2 to the carrier server device 30 via the wireless access point 20 corresponding to the SSID (step S11). In response to this connection request, the authentication unit 31 of the carrier server device 30 generates login screen data for authenticating the user and transmits it to the wireless terminal 10 (step S12). As a result, a login screen as illustrated in FIG. 6(A) is displayed on the wireless terminal 10. Since the user's location area can be determined from the SSID of the wireless access point 20 through which the connection request from the wireless terminal 10 has passed, in the example of FIG. There is. In other words, in this example, the wireless access point 20 through which the connection request from the wireless terminal 10 went is installed at XXX Stadium, and the user selects the wireless access point 20 installed at XXX Stadium from the list of available SSIDs. This means that the SSID of the access point 20 has been specified.

Here, when the user selects a login button as illustrated in FIG. 6A, the wireless terminal 10 transmits a login request including authentication information such as the user ID and password to the carrier server device 30 (step S13). These authentication information may be input into the login screen as shown in FIG. 6(A) and included in the login request. may be included in the login request.

In the carrier server device 30, the authentication unit 31 authenticates the user in response to the login request (step S14). This authentication is, for example, user authentication using the above authentication information.

Next, in the carrier server device 30, the acquisition unit 32 acquires user information regarding the authenticated user (step S15). Here, the acquisition unit 32 acquires different types of user information depending on the service provider server device 40 specified by the user. For this reason, the carrier server device 30 stores a processing table as illustrated in FIG. 5. In the example of FIG. 5, it is shown that the service provider server device 40 with the service provider server device ID “SID001” acquires user information of the type “ID, gender, age…” Regarding the service provider server device 40 whose provider server device ID is "SID002", it is shown that user information of the type "ID, address, location history..." is acquired, and the service provider server device ID is "SID002". Regarding the service provider server device 40 with "SID003", it is shown that user information of the type "ID, birthday..." is acquired, and the service provider server device with the service provider server device ID "SID004" Regarding the device 40, it is shown that user information of types such as "ID, connection information..." is acquired. Among these user information, static information such as ID, address, age, and birthday has been reported by the user to the carrier in advance, and the acquisition unit 32 reads it from the database storing this user information. and obtain it. In addition, among the user information, location history (chronological history of SSIDs of wireless access points 20 to which the wireless terminal 10 has connected, etc.), connection information (number of connections for each SSID, connection frequency, connection timing, connection time, etc.) The dynamic information can be obtained from a WLC (Wireless LAN Controller) or the like that controls each wireless access point 20, and the acquisition unit 32 obtains it by requesting the WLC or the like that stores this user information. Note that in the present invention, user information is not limited to the information exemplified in this embodiment.

In the communication carrier server device 30, the encryption unit 33 encrypts the acquisition unit using the encryption key corresponding to the decryption key held by the service provider server device 40 designated by the user among the plurality of service provider server devices 40. 32 is encrypted (step S16). Therefore, in the processing table illustrated in FIG. 5, an encryption key identifier is written for each service provider server device 40. In the example of FIG. 5, for example, the encryption key "Key1" is used for the service provider server device 40 with the service provider server device ID "SID001", and the service provider server device ID is "SID002". The encryption key "Key2" is used for the service provider server device 40, and the encryption key "Key3" is used for the service provider server device 40 with the service provider server device ID "SID003". The encryption key "Key4" is used for the service provider server device 40 with the device ID "SID004". All encryption keys identified by these identifiers are stored in the encryption unit 33.

In the carrier server device 30, the transmitting unit 34 generates standby screen data including user information encrypted by the encrypting unit 33 to the wireless terminal 10 (step S17), and transmits it (step S18). . This standby screen data is data for displaying a screen as illustrated in FIG. 6(B). In this screen data, the encrypted user information is written in the body part using, for example, the POST method in HTTP (Hyper Text Transfer Protocol). The POST method is one of the types of requests sent from a client (such as a web browser) to a server device (such as a web server) in HTTP, and is mainly used to transmit data from the client to the server device.

Upon receiving the above screen data, the wireless terminal 10 displays a standby screen as illustrated in FIG. 6(B), and further transfers the encrypted user information to the service provider server device 40 using the POST method. (Step S19).

In the service provider server device 40, the decryption unit 41 decrypts the encrypted user information transferred by the wireless terminal 10 with a decryption key corresponding to the encryption key used by the service provider server device 40 ( Step S20). For this reason, the decryption unit 41 of the service provider server device 40 stores the decryption key used by itself.

Then, in the service provider server device 40, the data transmitter 42 generates login completion data, which is presentation data for presenting to the user that the process for authenticating the user of the wireless terminal 10 (i.e., login) has been completed. (Step S21), and transmits to the wireless terminal 10 (Step S22). Upon receiving the login completion screen data, the wireless terminal 10 displays a login completion screen as illustrated in FIG. 6(C). This login completion screen displays user information such as a user name identified from the user's ID such as "Mr. A" and a service name identified from the user's birthday such as a soft button "Birthday present". Contains information-based content. That is, the data transmitter 42 includes content corresponding to the decrypted user information in the login completion screen data and transmits the data to the wireless terminal 10. Thereafter, various information is exchanged between the wireless terminal 10 and the service provider server device 40 according to a predetermined dialog screen, and services are provided from the service provider server device 40 to the wireless terminal 10.

According to the embodiment described above, the communication carrier can provide user information regarding the user of the wireless terminal 10 to various service providers.

When user information is provided from a telecommunications carrier to a service provider, it is encrypted and decrypted using an encryption key and decryption key held only by these carriers and service providers, so it cannot be leaked to a third party. The possibility of doing so is small. Here, from the perspective of keeping user information confidential, for example, the wireless terminal 10 is provided with user information in an unencrypted state from a communication carrier, and the wireless terminal 10 encrypts the user information and provides it to the service provider. A form of doing so is also conceivable. However, in such a configuration, since the user information in the wireless terminal 10 is in a so-called plain text state, the possibility of leakage from the wireless terminal 10 to a third party cannot be denied. In this embodiment, the possibility of such leakage to a third party can be eliminated.

In addition, the communication carrier server device determines communication procedures with each of the various service provider server devices according to each other's specifications, and exchanges encrypted user information according to communication procedures that differ for each service provider server device. Although it is conceivable to do so, it would require considerable effort to construct such a form. In contrast, in this embodiment, the communication carrier server device 30 communicates only with the wireless terminal 10, so the above-mentioned effort is reduced. In other words, according to this embodiment, provision of user information is realized in a simpler method.
