[0026]
As described above, in the embodiment of the present invention, since the authentication information is stored in the OS area not in the file format but in the encrypted binary format, the user of the portable information terminal 10 can read the contents of the authentication information. It is difficult to know.
[0027]
Even if the authentication information storage area is provided not in the OS area but in a part of the user area, confidentiality of the authentication information can be ensured by directly specifying the address and reading / writing.
[0028]
FIG. 3 is a flowchart of the automatic transmission process according to the first embodiment of the present invention, which is executed by the portable information terminal 10.
[0029]
When a call instruction is issued to the portable information terminal 10 (S101), the portable information terminal 10 acquires the name of the PHS card 20 (S102). Then, with the acquired PHS card name, the dedicated card database stored in advance is searched to determine whether the card is a dedicated card (S103). If the acquired PHS card name exists in the dedicated card database, it is determined that the card is a dedicated card, and the process proceeds to step S104 to perform an automatic calling process for the dedicated card. On the other hand, if the acquired PHS card name does not exist in the dedicated card database, it is determined that the card is not a dedicated card, and the process proceeds to step S201 to perform a normal calling process.
[0030]
In the dedicated card transmission process (S104 to S111), the access point telephone number stored in the connection information storage unit 11 of the portable information terminal 10 is read and acquired (S104). As will be described later, the access point telephone number is read out by directly specifying the address of the memory of the portable information terminal. Then, the obtained access point telephone number is sent to the PHS card 20 (S105), and a call to the access point telephone number is instructed (S106).
[0031]
When the PHS card 20 is connected to the base station 40 and a wireless communication line is set up between the PHS card 20 and the base station 40, the exchange connected to the base station 40 uses the access point telephone number to determine the authentication server 50 of the connection destination. Is specified, and the call is transferred to the specified authentication server 50 (S107).
[0032]
Then, the portable information terminal 10 waits for a request for authentication data from the authentication server 50 (S108). Upon receiving the authentication data request from the authentication server 50, the portable information terminal 10 reads and acquires the ID and password stored in the connection information storage unit 11 (S109), and stores the ID and password in the PHS card 20, the base station, and the like. The data is transmitted to the authentication server 50 via the server 40 (S110).
[0033]
The authentication server 50 uses an ID and password transmitted from the portable information terminal 10 and a terminal number (calling source telephone number) obtained at the time of transfer of a call generated from the PHS card 20 to store an authentication information storage unit. 55, if all of the authentication information including the ID, the password, and the terminal number match, the communication from the portable information terminal 10 is permitted, and the authentication completion signal is transmitted to the portable information terminal 10. I do.
[0034]
When the portable information terminal 10 receives the authentication completion signal, the authentication is successful, and the automatic transmission process ends (S111). On the other hand, if the authentication completion signal is not received within the predetermined time, the authentication is unsuccessful, so the line is disconnected (S112), and the automatic transmission process is terminated.
[0035]
Next, normal transmission processing (S201 to S211) will be described. In the normal transmission processing, the connection information cannot be automatically acquired from the connection information storage unit as in the above-described dedicated card transmission processing, so that the user of the portable information terminal 10 inputs the connection information.
[0036]
First, a connection information input screen is displayed to prompt the user to input connection information (S201). Then, when the user inputs the access point telephone number, ID and password (S202), it is determined whether or not the input has been completed normally (S203). Then, the input connection information (access point telephone number, ID, password) is stored in the connection information storage unit 11 (S204). Further, the input access point telephone number is sent to the PHS card 20 (S205), and a call to the access point telephone number is instructed (S206).
[0037]
When the PHS card 20 is connected to the base station 40 and a wireless communication line is set up between the PHS card 20 and the base station 40 (S207), the exchange connected to the base station 40 determines the connection destination based on the access point telephone number. The authentication server 50 is specified, and the call is transferred to the specified authentication server 50.
[0038]
Then, the portable information terminal 10 waits for a request for authentication data from the authentication server 50 (S208). Upon receiving the authentication data request from the authentication server 50, the portable information terminal 10 reads and acquires the ID and password stored in the connection information storage unit 11 (S209), and stores the ID and password in the PHS card 20, the base station, and the like. The data is transmitted to the authentication server 50 via the server 40 (S210).
[0039]
The authentication server 50 uses an ID and password transmitted from the portable information terminal 10 and a terminal number (calling source telephone number) obtained at the time of transfer of a call generated from the PHS card 20 to store an authentication information storage unit. 55, if all of the authentication information including the ID, the password, and the terminal number match, the communication from the portable information terminal 10 is permitted, and the authentication completion signal is transmitted to the portable information terminal 10. I do.
[0040]
When the portable information terminal 10 receives the authentication completion signal, the authentication is successful, and the automatic transmission process ends (S211). On the other hand, if the authentication completion signal is not received within the predetermined time, the authentication is unsuccessful, so that the line is disconnected (S212), and the automatic transmission process ends.
[0041]
FIG. 4 is a flowchart of the authentication processing according to the first embodiment of this invention, which is executed by the base station 40 and the authentication server 50.
[0042]
When the base station 40 detects a call from the PHS card 20 (S121), it negotiates a line connection between the base station 40 and the PHS card 20, a wireless communication line is set, and the PHS card 20 and the base station 40 is connected. Then, the exchange connected to the base station 40 specifies the authentication server 50 of the connection destination from the access point telephone number, and transfers the call to the specified authentication server 50.
[0043]
The authentication server 50 obtains the calling telephone number (terminal number of the PHS card 20) from the transferred call (S123). Then, an ID request signal for requesting an ID and a password is transmitted to the portable information terminal 10 (S124). If the ID and password cannot be obtained from the portable information terminal 10 within the predetermined time, the process returns to step S124, where the ID request signal is retransmitted, and the ID and password are again requested from the portable information terminal 10.
[0044]
On the other hand, when the ID and the password transmitted from the portable information terminal 10 are obtained (S125), the authentication information storage unit 55 is searched using the obtained authentication information (ID, password, terminal number), and the verification of the authentication information is performed. (S126).
[0045]
As a result of the search, if all of the authentication information including the ID, the password, and the terminal number match, an authentication completion signal is transmitted to the portable information terminal 10. Then, the service class corresponding to the ID is obtained from the authentication information storage unit 55, and the service class of the ID is set by the service class setting unit (S128). Then, a charging rate according to the service category is acquired, charging conditions are set (S129), updating of charging information corresponding to the ID is started, and charging for the ID is started (S130).
[0046]
On the other hand, as a result of the search, if any one of the authentication information composed of the ID, the password, and the terminal number does not match, an authentication disable signal is transmitted to the portable information terminal 10 to disconnect the line (S131).
[0047]
As described above, according to the first embodiment, the type of the connected PHS card 20 is determined, and if the card is a dedicated card, the calling processing for the dedicated card is performed, and the connection information storage unit 11 stores the information. Since a call is made to the authentication server 50 using the connection information that is present, there is no need for the user to input connection information. Further, since the connection information is not shown to the user, confidentiality of the connection information can be ensured.
[0048]
In addition, since authentication is performed using both the authentication information (ID and password) stored in the mobile information terminal 10 and the authentication information (terminal number) stored in the PHS card 20, different mobile information terminals 10 and PHS cards 20 are used. With the combination of the above, the authentication is not successful, and the impersonation of accessing the authentication server 50 by exchanging one of the portable information terminal 10 and the PHS card 20 can be prevented.
[0049]
Further, since the computer device can be specified from the wireless data communication device in the authentication server of the communication carrier, it is necessary to provide a service corresponding to the type of the computer device, set a fee corresponding to the service, and charge. Can be. Moreover, by performing this specification in the authentication server of the communication carrier, the versatility of the wireless data communication device itself is not impaired.
[0050]
FIG. 5 is a flowchart of the automatic transmission process according to the second embodiment of the present invention, which is executed by the portable information terminal 10. In the second embodiment, unlike the first embodiment (FIGS. 3 and 4), authentication is performed using the unique number of the portable information terminal 10 in addition to the ID, password, and terminal number.
[0051]
When a call instruction is issued to the portable information terminal 10 (S141), the portable information terminal 10 acquires the name of the PHS card 20 (S142). Then, the dedicated card database stored in advance is searched using the acquired PHS card name, and it is determined whether or not the card is a dedicated card (S143). If the acquired PHS card name exists in the dedicated card database, it is determined that the card is a dedicated card, and the process proceeds to step S144 to perform an automatic calling process for the dedicated card. On the other hand, if the acquired PHS card name does not exist in the dedicated card database, it is determined that the card is not a dedicated card, and the process proceeds to step S201 to perform a normal calling process.
[0052]
In the dedicated card transmission process (S144 to S156), the access point telephone number stored in the connection information storage unit 11 of the portable information terminal 10 is read and acquired (S144). As will be described later, the access point telephone number is read out by directly specifying the address of the memory of the portable information terminal. Then, the obtained access point telephone number is sent to the PHS card 20 (S145), and a call to the access point telephone number is instructed (S146).
[0053]
When the PHS card 20 is connected to the base station 40 and a wireless communication line is set up between the PHS card 20 and the base station 40, the exchange connected to the base station 40 uses the access point telephone number to determine the authentication server 50 of the connection destination.

Upon receiving the authentication data request from the authentication server 50, the portable information terminal 10 reads and acquires the ID and password stored in the connection information storage unit 11 (S149), and stores the ID and password in the PHS card 20, the base station, and the like. The data is transmitted to the authentication server 50 via the server 40 (S150).
[0055]
The authentication server 50 uses an ID and password transmitted from the portable information terminal 10 and a terminal number (calling source telephone number) obtained at the time of transfer of a call generated from the PHS card 20 to store an authentication information storage unit. If all of the authentication information including the ID, the password, and the terminal number match (S151), the mobile information terminal 10 is queried for the unique number of the mobile information terminal 10. On the other hand, if any of the ID, the password, and the terminal number do not match, the line is disconnected (S156), and the automatic calling process ends.
[0056]
Upon receiving the unique number request signal, the portable information terminal 10 reads out and acquires the unique number stored in the ROM (or RAM) of the portable information terminal 10 (S152), and stores the unique number in the PHS card 20 and the base station 40. Is transmitted to the authentication server 50 via the server (S153).
[0057]
The authentication server 50 searches the authentication information storage unit 55 using the unique number transmitted from the portable information terminal 10, and finds that the unique number is the authentication information (the combination of the ID, the password, and the terminal number) specified in S151. Is determined (S154). If all of the authentication information including the ID, the password, the unique number, and the terminal number match, the communication from the portable information terminal 10 is permitted, and an authentication completion signal is transmitted to the portable information terminal 10. . On the other hand, if the unique number does not match the other authentication information (ID, password, terminal number), the line is disconnected (S156), and the automatic calling process ends.
[0058]
When the portable information terminal 10 receives the authentication completion signal, the authentication is successful, and the automatic transmission process ends (S155). On the other hand, if the authentication completion signal is not received within the predetermined time, the authentication is unsuccessful, so that the line is disconnected (S212), and the automatic transmission process ends.
[0059]
Next, normal transmission processing (S201 to S212) will be described. Since this normal transmission processing is the same as the normal transmission processing shown in FIG. 3, the same step numbers are given and the detailed description is omitted.
