Abstract

In a method and an apparatus for multi-destination communication processing in a packet storage/exchange node, a line control module controls transmission and reception of a message that contains either a single destination message or a multi-destination message to and from a telephone subscriber line. A file storage stores the message in accordance with delivery destination addresses, and a file control module controls writing the message received from the line control module into the file storage and reading the message from the file storage to supply the message to the line control module. At least one multi-destination message tempeorary storage area of a multi-destination message temporary storage included in a multi-destination message storing/processing module temporarily stores a multi-destination message and at least one single destination message storage area of the multi-destination message temporary storage stores individual single destination messages expanded from the multi-destination message.
