Abstract

A base station, in a mobile communication network, includes a receive component to receive, from a higher rank station in the network, a particular data unit that includes multiple data units multiplexed together; a master processor to determine that the first portion of the particular data unit is destined for the base station and that the second portion of the particular data unit is not destined for the base station, and discard the second portion of the particular data unit; and a slave processor to determine that the second portion of the particular data unit is destined for the other base station and that the first portion of the particular data unit is not destined for the other base station, and send the second portion of the particular data unit to the other base station.

Claims

1. A base station modulator/demodulator for constituting a mobile communication system and sending ATM cells to a higher rank station and receiving ATM cells from the higher rank station, said base station modulator/demodulator comprising:

receive means for terminating, among ATM cells received from the higher rank station through a leased line, ATM cells addressed to the base station;

first send means for sending, among the ATM cells received from the higher rank station through the leased line, ATM cells addressed to another base station to the another base station; and

second send means for multiplexing ATM cells of a plurality of base stations, said base station and said another base station, and sending the multiplexed cells to the higher rank station through the leased line.
