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. The method of claim 10, where determining whether the element of the header portion of the one of the plurality of cells is associated with the first base station or the one or more other base stations includes:

determining whether the element of the header portion of the one of the plurality of cells matches a value associated with the first base station or the one or more other base stations.

12. The method of claim 10, where determining whether the element of the header portion of the one of the plurality of cells is associated with the first base station or the one or more other base stations includes:

identifying a virtual path identifier in the header portion of the one of the plurality of cells; and

determining whether the identified virtual path identifier is associated with the first base station or the one or more other base stations.

13. The method of claim 7, where multiplexing the data with the other data includes:

multiplexing the data with the other data based on a band value associated with the leased line.

14. A system comprising:

a first base station connected to a higher rank base station via a leased line and one or more other base stations via one or more other lines, the first base station to;

determine a portion of a bandwidth of the leased line utilized to transmit data to the higher rank station,

multiplex, based on the portion of the bandwidth of the leased line utilized to transmit the data, the data with other data from the one or more other base stations, and

transmit the multiplexed data to the higher rank base station.

15. The system of claim 14, where the first base station is further to:

receive data, via the leased line, from the higher rank base station, where the data comprises a plurality of cells,

determine whether an element of a header portion of one of the plurality of cells of the data is associated with the first base station or the one or more other base stations,

terminate, when the first element of the header portion of the one of the plurality of cells of the data is associated with the first base station and not the one or more other base stations, the one of the plurality of cells of the data, and

transmit, when the first element of the header portion of the one of the plurality of cells is associated with the one or more other base stations and not the first base station, the one of the plurality of cells of the data to the one or more other base stations.

16. The system of claim 14, where the first base station is further to:

receive the other data from the one or more other base stations, where the other data includes idle data and comprises a frame format associated with a transmission rate capacity of the leased line.

17. The system of claim 14, where the one or more other base stations include a second base station and a third base station, and the first base station is further to:

receive the other data from the second base station, where the other data includes data received by the second base station from the third base station.

18. The system of claim 14, where the first base station multiplexes the data with the other data based on a band value associated with the leased line.

19. The system of claim 14, where the one or more other base stations include a second base station and a third base station, and the second base station is to:

determine a portion of a bandwidth of one of the one or more other lines utilized, by the second base station, to transmit a portion of the other data to the first base station,

multiplex, based on the portion of the bandwidth of the one of the one or more other lines utilized to transmit the portion of the other data, the portion of the other data with other data received from the third base station, and

transmit the multiplexed other data to the first base station.

20. The system of claim 19, where the second base station is further to:

receive data, via the one of the one or more other lines, from the first base station, where the received data comprises a plurality of cells,

determine whether an element of a header portion of one of the plurality of cells of the received data is associated with the second base station or the third base station,

terminate, when the first element of the header portion of the one of the plurality of cells of the received data is associated with the second base station and is not associated with the third base station, the one of the plurality of cells of the received data, and
