The efficient management and sharing of the spectrum among the users is an important
issue, frequency channels have to be reused as much as possible in order to support the many
thousands of simultaneous call in any typical of mobile system. In cellular architecture, cell is
serviced by a base station located at its center. A number of cells are linked to a mobile switching
center which also acts as a gateway of the cellular network to the existing wired networks liked
PSTN, ISDN or LAN-WAN based networks. A base station communicates with the mobile station
through wireless links, and with the MSC’s through wire-line links. This paper deals with some
estimations on efficient of distribute channel allocation scheme for cellular networks and then
LBSB scheme is selected to improve it’s efficient, that is, the first, channel borrowing is not only
neighbours but in compact pattern and the second, when a cell become hot, it repeat to borrow
channel until reaching average degree of coldness of networks, that mean X=C.(dc
