  In the electronic system of the present embodiment, both the telephone terminal 1 and the portable terminal 2 have an electronic mail function. In the telephone system of the present embodiment, presence information is transmitted from the portable terminal 2 to the telephone terminal 1 using this electronic mail function.

  FIG. 2A is a sequence diagram for explaining a first operation example when mobile terminal 2 transmits its terminal state as presence information to telephone terminal 1 in the telephone system according to the present embodiment. is there.

  When the telephone terminal 1 accepts a partner terminal confirmation instruction with designation of the portable terminal 2 from the user (S101), the telephone terminal 1 sends an email (presence terminal request confirmation mail for partner terminal confirmation) to confirm the terminal state of the portable terminal 2. Generate. Then, this partner terminal confirmation presence survey request mail is transmitted to the portable terminal 2 designated by the user (S102).

  Receiving this, the portable terminal 2 acquires the terminal state of the own terminal 2 such as a call state, presence / absence of manner mode setting, and GPS information (S103). Here, it is assumed that the mobile terminal 2 is in a call-ready state (a state where the call state is “standby” and the manner mode setting is “none”). The portable terminal 2 generates an e-mail (presence notification mail for own terminal) for notifying the acquired terminal state of the own terminal 2 as presence information. Then, the self-terminal presence notification mail is transmitted to the telephone terminal 1 that is the transmission source of the partner terminal confirmation presence survey request mail (S104).
