For example, <class1> is the immediate upper layer of <class1x>, <class11> is the immediate upper layer of class <class11x>, <class12> is the immediate upper layer of class <class12x>, and <class13 > Are located in the immediate upper layer of the class <class13x>, respectively. The text data 1113 includes a name of a folder or file at a target position on the directory hierarchy, and a character string indicating whether the name is a folder name or a file name ("fol", " fil "). The icon 1112 is formed including a character string represented by the text data 1113.

  The mail analysis unit 113 analyzes the electronic mail received from the mail transmission / reception unit 104 and determines whether it is a menu request mail or an operation content notification mail received from the mobile terminal 2. Here, the menu request mail is a blank e-mail that includes a character string indicating that it is a menu request mail for a telephone function / presence operation or content operation in the title and has no mail body. Further, the operation content notification mail includes a character string indicating that it is a telephone function / presence operation or content operation operation notification mail in the title, and includes authentication information (ID, password and user name) and remote operation execution item. This icon information 1110 is an e-mail expanded in the mail text.

  FIGS. 6A to 6C are diagrams schematically illustrating an example of the operation content notification mail. As shown in the figure, the operation content notification mail includes a character string indicating that it is an operation content notification mail in the title 2120, and the authentication information 2122 and the icon information 1110 of the remote operation execution item are expanded in the mail body 2121. ing.

  In the example shown in FIGS. 6A to 6C, the icon 1112 is not included in the icon information 1110 developed in the mail body 2121. However, it may be included.

  If the electronic mail received from the mail transmission / reception unit 104 is an electronic mail other than the menu request mail and the operation content notification mail, the mail analysis unit 113 passes the electronic mail to the mail function unit 105. On the other hand, if it is a menu request mail, an instruction for generating a menu notification mail for the telephone function / presence operation or content operation specified in the menu request mail is sent to the mail address of the portable terminal 2 which is the transmission source of the menu request mail. At the same time, the menu notification mail generator 112 is notified. If it is an operation content notification mail, the operation content is extracted from the operation content notification mail, and the telephone function setting unit 108 and the presence information setting unit 109 or the content storage control unit 107 are controlled according to the operation content.

  FIG. 7 is a flowchart for explaining the operation of the telephone terminal 1 when a menu request mail is received from the portable terminal 2.

  First, the mail analysis unit 113 determines whether the menu request mail is a telephone request / presence operation menu request mail or a content operation menu request mail (S101). Specifically, the title of the menu request mail is analyzed, and a character string indicating that it is a menu request mail for telephone function / presence operation is included, or a character string indicating that it is a menu request mail for content operation Is included.

  Next, if the menu request mail is a telephone request / presence operation menu request mail (“telephone function / presence operation” in S101), the mail analysis unit 113 issues a telephone function / presence operation menu notification mail generation instruction. The menu notification mail generation unit 112 is notified together with the mail address of the portable terminal 2 that is the transmission source of the menu request mail.

  In response to this, the menu notification mail generation unit 112 reads all the icon information 1110 (see FIG. 4A) of the telephone function / presence operation from the icon information storage unit 111 (S102). Further, the operation application is read from the operation application storage unit 110 (S106).

  Next, the menu notification mail generation unit 112 generates a menu notification mail for a telephone function / presence operation. Specifically, it generates a blank e-mail that includes a character string indicating that it is a menu notification mail for the telephone function / presence operation in the title and does not include the body of the mail. To do. Then, the telephone function / presence operation menu notification mail 1110 and the operation application are attached to the telephone function / presence operation menu notification mail (S107), and the telephone function / presence operation menu notification mail is sent to the mail transmitting / receiving unit 104 and the communication interface. It transmits to the portable terminal 2 which is the transmission origin of a menu request | requirement mail via the part 101 (S108).

  On the other hand, if the menu request mail is a content operation menu request mail (“content operation” in S101), the mail analysis unit 113 sends a content operation menu notification mail generation instruction to the mobile phone that is the source of the menu request mail. The menu notification mail generation unit 112 is notified together with the mail address of the terminal 2.

  In response to this, the menu notification mail generation unit 112 reads all the icon information 1110 (see FIG. 4B) for content operation from the icon information storage unit 111 (S103). Further, the directory information of the content storage unit 106 is acquired from the content storage control unit 107 (S104). Then, content operation icon information 1110 as shown in FIG. 5 is generated according to the directory hierarchical structure indicated by the acquired directory information (S105). Further, the operation application is read from the operation application storage unit 110 (S106).

  Next, the menu notification mail generation unit 112 generates a menu notification mail for content operation. Specifically, a blank electronic mail including a character string indicating that it is a content operation menu notification mail in the title and having no mail body is generated, and this is used as the content operation menu notification mail. Then, the content operation icon information 1110 and the operation application are attached to the content operation menu notification mail (S107), and the content operation menu notification mail is sent to the menu request mail via the mail transmitting / receiving unit 104 and the communication interface unit 101. (S108).

  FIG. 8 is a flowchart for explaining the operation of the telephone terminal 1 when an operation content notification mail is received from the portable terminal 2.

  First, the mail analysis unit 113 performs an operation content notification mail authentication process (S121). Specifically, authentication information 2122 is extracted from the mail body 2121 and it is determined whether or not this authentication information 2122 is registered in advance as authentication information of a user who permits remote operation. If the authentication fails (NO in S122), the mail analysis unit 113 performs a predetermined error process (S141). For example, the mail function unit 105 is caused to generate an e-mail in which an error message is described, and this e-mail is sent to the portable terminal 2 that is the transmission source of the operation content notification mail via the mail transmission / reception unit 104 and the communication interface unit 101. Send it.

  On the other hand, if the authentication is successful (YES in S122), the mail analysis unit 113 determines whether the operation content notification mail is an operation content notification mail for a telephone function / presence operation or an operation content notification mail for a content operation. (S123). Specifically, the operation content notification mail title 2120 is analyzed, and a character string indicating that the operation content notification mail for the telephone function / presence operation is included or the operation content notification mail for the content operation is included. It is determined whether a character string indicating is included.

  Next, if the operation content notification mail is a telephone function / presence operation operation content notification mail (“telephone function / presence operation” in S123), the mail analysis unit 113 uses the mail content 2121 of the operation content notification mail to call the telephone. The control command for the function operation is extracted (S124). Specifically, icon information 1110 including class information 1111 (<class 5> and <class 6> in FIG. 4A) corresponding to the control command for telephone function operation is searched from the mail body 2121, and the searched icon information.
