System and method for passive optical network backhaul

摘要

A system is described for providing backhaul over an Ethernet passive optical network (EPON). The backhaul may be backhaul for EV-DO and/or EV-DO Rev. A communications. The system for includes at least one cell site. At least two base transceiver stations are located at the cell site. The base transceiver stations receive radio signals from respective mobile stations. A first one of the base transceiver stations provides a first backhaul signal, and a second one of the base transceiver stations provides a second backhaul signal. The cell site multiplexes these backhaul signals together onto an Ethernet passive optical network. In one embodiment, these signals are provided on different pseudowire connections within a single wavelength lambda on the passive optical network. In another embodiment, the signals are provided on different lambdas of the network.

1. A backhaul method comprising:
receiving a first radio signal at a first base transceiver station; receiving a second radio signal at a second base transceiver station; generating a first backhaul signal from the first radio signal; generating a second backhaul signal from the second radio signal; multiplexing the first and second backhaul signals into respective first and second pseudowire connections on an Ethernet passive optical network, wherein the first base transceiver station communicates with a first mobile switching center over the first pseudowire connection, and the second base transceiver station communicates with a second mobile switching center over the second pseudowire connection; receiving the first backhaul signal and the second backhaul signal at a first mobile switching center; relaying the second backhaul signal from the first mobile switching center to the second mobile switching center; and receiving the relayed second backhaul signal at the second mobile switching center; wherein the first base transceiver station and the first mobile switching center are operated by a first service provider; and wherein the second base transceiver station and the second mobile switching center are operated by a second service provider different from the first service provider.
