The mail protocol is information indicating which mail protocol POP3 or IMAP4 is used by the information terminals 13, 23, and 33.

(5) Storage Contents of Template Information Storage Unit Next, storage contents of the template information storage unit 55c will be described.
FIG. 5 is a format diagram showing an example of the contents stored in the template information storage unit 55c. As shown in the figure, the template information storage unit 55c stores a template in which communication parameter names and communication parameter values that can be understood by the software are described for each Internet connection software. This template is added to the e-mail transmitted from the communication parameter distribution server 50b to the information terminals 13, 23, and 33 by MIME (Multipurpose Internet Mail Extensions).

Hereinafter, each communication parameter will be described by taking the template of the Internet connection software SF1 shown in the figure as an example.
First, “Content-Type” is header information that specifies a MIME format to be added to an e-mail. “Application / autoconf”, which is a communication parameter value corresponding to “Content-Type”, instructs activation of communication parameter setting software “autoconf” installed in the information terminals 13, 23, 33. That is, the information terminals 13, 23, and 33 that have received the MIME header “Content-Type: application / autoconf” start the communication parameter setting software “autoconf”, and then transmit the communication parameters transmitted subsequently to the Internet connection software. It is supposed to be set to.
Communication parameter names "DialupNumber", "DNSIAddress1", "DNSIAddress2", "SmtpServerName", "PopServerName", "ImapServerName", "UserID", "UserPassward", "DialupType", "Content-Type" “MailUserID”, “MailAddress”, “MailPassword”, and “MailProtocol” are character strings that can be understood as communication parameter names by the Internet connection software SF1. That is, these communication parameter names are unique to each communication software. For example, the communication parameter name of the Internet connection software SF1 and the communication parameter name of the Internet connection software SF2 are different.
“DialupNumber” means the telephone numbers of the access points 50a-1 to 50a-3, and the communication parameter value is set to “# 1111” for the access point 50a-1 of the cellular phone network 12, and the mobile packet communication network “# 2222” is set for the 22 access point 50 a-2, and “# 3333” is set for the access point 50 a-3 of the simple mobile phone network 32.
“DNSIAddress1” is the IP address of the primary DNS server 50c, and “DNSIAddress2” is the IP address of a secondary DNS server (not shown). “SmtpServerName” is the server name of the SMTP server 50d, “PopServerName” is the server name of the POP server 50e, and “ImapServerName” is the server name of the IMAP server 50f.
The communication parameter values corresponding to the above communication parameter names “DialupNumber” to “ImapServerName” do not depend on the type of the Internet connection software or the user attribute, and are common.

Next, the communication parameter names “UserPassward”, “DialupType”, “MailUserID”, “MailAddress”, “MailPassword” and “MailProtocol” described below “UserID” are “%% user ID%”, respectively. % "," %% password %% "," %% mobile device type %% "," %% mail user ID %% "," %% mail address %% "," %% mail password %% "," Communication parameter value "%% mail protocol %%" is set. These communication parameter values are replaced with communication parameter values depending on user attributes.
Specifically, this replacement process is performed as follows. First, as described above, user information is extracted from the user information storage unit 55b using the caller number as a search key. Next, the extracted user information and the corresponding character strings of “%% user ID %%” to “%% mail protocol %%” are replaced. For example, the user ID “user00123” extracted from the user information storage unit 55b is replaced with “%% user ID %%” on the template.

  Here, FIG. 6 shows an example of communication parameters distributed to the information terminal 13 by the communication parameter distribution server 50b. In the figure, for example, “DialupNumber” is the portable device type “1” obtained by referring to the user information storage unit 55b using the caller number transmitted from the information terminal 13 and the mobile phone 10 as a search key. Correspondingly, it is “# 1111” which is the telephone number of the access point 50a-1 of the mobile phone network 12.

B: Operation Next, the operation of the embodiment configured as described above will be described. First, when the information terminal 13, 23, 33 requests the communication parameter distribution server 50b to distribute the communication parameter, the communication parameter distribution server 50b distributes the communication parameter to the information terminal 13, 23, 33 accordingly. It is set in the internet connection software of the information terminals 13, 23, 33.
The following description will be divided into (1) an operation on the information terminal 13, 23, 33 side of communication parameter request / setting, and (2) an operation on the communication parameter distribution server 50b side of communication parameter distribution.

It is a schematic diagram which shows an example of the screen transition displayed on a display part.
In FIG. 7, when a predetermined key operation is performed by the user, the CPU 13a loads a communication parameter setting program from the hard disk device 13d onto the RAM 13c, and the process proceeds to step Sa1. In step Sa1, the CPU 13a displays the screen shown in FIG. 8A and prompts the user to set communication parameters.

Next, the processing of the CPU 13a proceeds to step Sa2. In step Sa2, the CPU 13a scans the key operation unit and determines whether or not a key operation indicating a communication parameter setting instruction has been performed.
If there is no key operation indicating a setting instruction, the determination result in step Sa2 is “No”, and thereafter this determination is repeated.
On the other hand, if there is a key operation indicating a setting instruction, the determination result in step Sa2 is “Yes”, and the process proceeds to step Sa3.

  In step Sa3, the CPU 13a acquires the software name of the Internet connection software stored in the hard disk device 13d. For example, when the software is stored in a file format, the CPU 13a refers to a file management table in which attribute information of files stored in the hard disk 13d is described, and acquires the software name of the Internet connection software. In step Sa3 and step Sa4 described later, the CPU 13a displays the screen shown in FIG. 8B.

  Next, the processing of the CPU 13a proceeds to step Sa4. In step Sa4, the CPU 13a generates a request signal for requesting communication parameter delivery. This request signal includes the software name of the Internet connection software acquired in step Sa3.

Next, the process of the CPU 13a proceeds to step Sa5. In step Sa5, the CPU 13a instructs the mobile phone 10 to call the access point 50a-1, connects the communication line with the center 50, and transmits the request signal generated in step Sa4 to the center 50. The telephone number “# 1111” when calling the access point 50a-1 is input by the user's key operation. As described above, when the mobile phone 10 transmits a request signal to the center 50, the caller number of the mobile phone 10 is added to the request signal.
In step Sa5, the CPU 13a displays the screen shown in FIG. 8C.

After the transmission of the request signal, the processing of the CPU 13a proceeds to step Sa6 and starts time counting. This time count is performed for a timeout process to be described later when a communication parameter value is not received from the center 50 within a predetermined time.
Next, in step Sa7, the CPU 13a determines whether or not a communication parameter value has been transmitted from the center 50 within a predetermined time.
If the communication parameter value is not transmitted, the determination result in step Sa7 is “No”, the process proceeds to step Sa8, an error screen due to timeout as shown in FIG. 8D is displayed, and the process ends.
On the other hand, if the communication parameter value is transmitted within a predetermined time, the determination result in step Sa7 is “Yes”, and the process proceeds to step Sa9.

In step Sa9, the CPU 13a sets the received communication parameter value in the Internet connection software. This setting is performed by describing the transmitted communication parameter values in corresponding positions on the Internet connection software.
When the setting process ends, the CPU 13a displays an end notification screen as shown in FIG. 8E and ends the process.

(2) Communication Parameter Distribution in Communication Parameter Distribution Server 50b Next, an operation in which the CPU 51 of the communication parameter distribution server 50b distributes communication parameters to the information terminal 13 will be described with reference to the flow shown in FIG.
As described above, the communication parameter setting request signal is transmitted to the communication parameter distribution server 50 b together with the caller number of the mobile phone 10. In response to this, the CPU 51 of the communication parameter distribution server 50b activates the communication parameter distribution program, and the process of step Sb1 in FIG. 9 is started. In step Sb1, the CPU 51 searches the user information storage unit 55b of the hard disk device 55 using the received caller number as a search key, and acquires corresponding user information.

  Next, the process proceeds to step Sb2. In step Sb2, the CPU 51 searches the template information storage unit 55c of the hard disk device 55 using the software name of the Internet connection software included in the received request signal as a search key, and acquires the corresponding template.

  Next, the process of the CPU 51 proceeds to step Sb3. In step Sb3, the CPU 51 replaces the user information acquired in step Sb1 with the character strings “%% user ID %%” to “%% mail protocol %%” on the template acquired in step Sb2. Various communication parameter values are described in the template.

  Next, the processing of the CPU 51 proceeds to step Sb4. In step Sb4, the CPU 51 adds the template describing the communication parameter value to the e-mail addressed to the mobile phone 10 and transmits it, and the process ends.

  According to the embodiment described above, the user sets communication parameters according to the type and user attribute of the Internet connection software in the software only by performing a simple operation without knowing specific communication parameter values. be able to.
