Claim Text:
1. A baseband processing unit, comprising: a backplane and at least two baseband processing boards, wherein each of the baseband processing boards comprises a baseband processing module, a power supply module and an optical module, and at least one of the baseband processing boards further comprises: a first direct path connected in parallel with the baseband processing module and a second direct path connected in parallel with the power supply module; in the case that failures occur on both the baseband processing module and the power supply module in a first baseband processing board comprising the first direct path and the second direct path, the first baseband processing board operates in a first operation mode, wherein the first operation mode comprises: obtaining baseband processing resources and power supply required for operation via the backplane, providing the obtained baseband processing resources to a corresponding radio remote unit via the first direct path and the optical module, and providing the obtained power supply to the optical module via the second direct path; and in the case that a failure occurs on the baseband processing module in the first baseband processing board, but no failure occurs on the power supply module in the first baseband processing board, the first baseband processing board operates in a second operation mode, wherein the second operation mode comprises: obtaining the baseband processing resources required for operation via the backplane, providing the obtained baseband processing resources to the corresponding radio remote unit via the first direct path and the optical module, and supplying the optical module with power by the power supply module of the baseband processing board.
