Abstract
A plurality of terminals communicate. One terminal belongs to a plurality of groups of terminals. In the communication apparatus, a terminal information memory stores terminal identifiers. A sending section sends the communication information with the terminal identifiers of other terminals participating in one group to the other terminals. A receiving section receives information sent by the other terminal. A group discrimination section compares the received terminal identifiers with the stored terminal identifiers, and discriminates the group from which the received information was communicated according to the comparison.
