摘要

PURPOSE: A communication method of being possible to voice communication and data communication is provided to use a main number registered with plural connection numbers, and to perform voice communication and data communication by an exchange unit for performing connection after judging whether a terminal of a caller is for voice communication or data communication. CONSTITUTION: An exchange unit receives a main number(S200). The exchange unit decides whether the main number is subscribed in a subscriber database(S210). If not, the exchange unit delivers a missing number announcement to a user(S220). If the main number is subscribed, the exchange unit decides whether an originator accesses with a terminal for voice communication, or for data communication(S230). If the originator accesses with the terminal for voice communication, the exchange unit sorts connection numbers available for voice communication(S241). The exchange unit delivers announcement in order to make the originator choose a number(S242). The exchange unit automatically connects a call with a chosen number(S243). If the originator accesses with the terminal for data communication(S250), announcement that the originator can choose a desired number is delivered(S251). The exchange unit decides whether the originator performs data communication(S252). If so, the exchange unit transmits a URL to a URL SMS transmission unit, and the URL¡¡SMS transmission unit transmits the URL by using an SMS to the originator(S253).
