Base station modulator/demodulator and send/receive method
First Claim
1. A modulator/demodulator comprising:
- an interface to;
terminate a physical layer transmitting multiplexed data, received at the modulator/demodulator from a particular station in a mobile communication system, wherein first data units, of the multiplexed data, are destined for the modulator/demodulator and second data units, of the multiplexed data, are destined for another modulator/demodulator, each of the data units having an associated virtual path identification (VPI),transfer the first data units to a first processor and a second processor, andtransfer the second data units to the first processor and the second processor;
the first processor comprising;
a first VPI filter to discard the transferred data units having an associated VPI that differs from a set value assigned to the modulator/demodulator; and
the second processor comprising;
a second VPI filter to identify the transferred data units having an associated VPI that matches a set value assigned to the other modulator/demodulator.

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.

11. A method comprising:
-
receiving, at an interface of a modulator/demodulator, multiplexed data transmitted from a particular station in a mobile communication system, wherein first data units, of the multiplexed data, have an associated virtual path identification (VPI) addressed to the modulator/demodulator, and second data units, of the multiplexed data, have an associated VPI addressed to another modulator/demodulator; transferring, by the interface, the first data units to a first processor and a second processor; transferring, by the interface, the second data units to the first processor and the second processor; discarding, at the first processor, the second data units based on the associated VPI; and discarding, at the second processor, the first data units based on the associated VPI. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A mobile communication system comprising:
-
a network; a first base station, connected to the network via a first leased line, including; an interface to; terminate a physical layer transmitting multiplexed data, received at the first base station from a particular station in the network, wherein first data units, of the multiplexed data, are destined for the first base station and second data units, of the multiplexed data, are destined for a second base station, each of the data units having an associated virtual path identification (VPI), transfer the first data units to a first processor and a second processor, and transfer the second data units to the first processor and the second processor; the first processor comprising; a first VPI filter to discard the transferred data units having an associated VPI that differs from a first value assigned to the first base station; and the second processor comprising; a second VPI filter to identify the transferred data units having an associated VPI that matches a second value assigned to the second base station; and the second base station, connected to the first base station via a second leased line.
