Abstract
The invention provides a wireless access system and a wireless service processing method. By virtue of the concentrated arrangement of base band unit (BBU) servers, the system and the method can be used for solving the problems that the number of services which can be processed by each BBU is limited because the BBU independently processes signals from each cell of a base station in the prior art, for example, when the load of a certain cell is increased and cannot be processed by the current BBU, the increased load of the cell cannot be processed until a new BBU is added or the current BBU is replaced by a new BBU with higher processing capacity, or when the load of a certain cell is reduced, the idling processing capacity of the current BBU cannot be used for processing the signals from the cells of other base stations. Therefore, the signal processing of a plurality of BBUs in the prior art can be finished at a node, and the loads of all the cells share the processing capacities of the BBU servers, so that the utilization rates of the BBU servers are further increased; and furthermore, as the BBU servers are arranged concentratively, the BBU servers are convenient to maintain and relatively low in cost.
