We study the mass and different RR charge distributions of the BPS (p,p - 2
)-brane bound states in the closed string brane-like sigma-model. We show t
hat such brane bound states can be realized by introducing a constant B fie
ld in the closed string theory. In addition we show that the worldvolume co
ordinates of these brane bound states turn out to be noncommutative. (C) 20
