A soft handover processing method, wherein an extended soft handover area between a macro cell and a low-power cell is divided into an Uplink, UL, soft combining gain area and a Downlink, DL, soft combining gain area, in the soft handover area, an User Equipment, UE, have Radio Links, RLs, with the macro cell and the low-power cell simultaneously, and the method comprises: receiving, by a Radio Network Controller, RNC, an event measurement report reported by the UE; and when it is determined that the UE enters the UL soft combining gain area from the macro cell, enters the DL soft combining gain area from the UL soft combining gain area, enters the low-power cell from the DL soft combining gain area, enters the DL soft combining gain area from the low-power cell, enters the UL soft combining gain area from the DL soft combining gain area or enters the macro cell from the UL soft combining gain area according to the event measurement report, executing a corresponding soft handover strategy respectively; wherein the soft handover area is extended by following: regulating a Cell Individual Offset, CIO, of the low-power cell, enhancing transmitted power of a P-CPICH of the low-power cell and enhancing transmitted power of a broadcast channel of the low-power cell, so that a boundary, close to a macro Node B side, of the soft handover area is the same as a UL boundary of an unbalance area, an unbalance area being an area where the macro cell pilot power received by UE in the UL boundary is DU, dB, higher than the low-power pilot received from the low power cell, or, an area where the transmitted signal power, received by the low-power cell, of the UE in the DL boundary is DU, dB, higher than transmitted signal power, received by the macro cell, of the UE in the DL boundary, the UL boundary referring to a boundary location where UL path loss from UE to a macro cell is equal to the UL path loss from the UE to a low-power cell and a DL boundary referring to a boundary location where a macro cell pilot and a low-power cell pilot received by the UE are equal, or, regulating a CIO of a low-power cell, enhancing transmitted power of a Primary Common Pilot Channel, P-CPICH, of the low-power cell and enhancing transmitted power of a broadcast channel of a cell of a low-power Node B, so that the soft handover area includes the UL boundary of the unbalance area. receiving, by a Radio Network Controller, RNC, an event measurement report reported by the UE; and when it is determined that the UE enters the UL soft combining gain area from the macro cell, enters the DL soft combining gain area from the UL soft combining gain area, enters the low-power cell from the DL soft combining gain area, enters the DL soft combining gain area from the low-power cell, enters the UL soft combining gain area from the DL soft combining gain area or enters the macro cell from the UL soft combining gain area according to the event measurement report, executing a corresponding soft handover strategy respectively; wherein the soft handover area is extended by following: regulating a Cell Individual Offset, CIO, of the low-power cell, enhancing transmitted power of a P-CPICH of the low-power cell and enhancing transmitted power of a broadcast channel of the low-power cell, so that a boundary, close to a macro Node B side, of the soft handover area is the same as a UL boundary of an unbalance area, an unbalance area being an area where the macro cell pilot power received by UE in the UL boundary is DU, dB, higher than the low-power pilot received from the low power cell, or, an area where the transmitted signal power, received by the low-power cell, of the UE in the DL boundary is DU, dB, higher than transmitted signal power, received by the macro cell, of the UE in the DL boundary, the UL boundary referring to a boundary location where UL path loss from UE to a macro cell is equal to the UL path loss from the UE to a low-power cell and a DL boundary referring to a boundary location where a macro cell pilot and a low-power cell pilot received by the UE are equal, or, regulating a CIO of a low-power cell, enhancing transmitted power of a Primary Common Pilot Channel, P-CPICH, of the low-power cell and enhancing transmitted power of a broadcast channel of a cell of a low-power Node B, so that the soft handover area includes the UL boundary of the unbalance area.
