摘要： A method and an apparatus for correcting wireless signal quality are provided. The apparatus includes an abnormality detector and a quality adjuster. The abnormality detector collects multiple measurement values reported by a user equipment (UE), calculates a variation degree value according to the measurement values, and compares the variation degree value with a predetermined threshold value. The measurement values are generated by the UE when the UE measures the wireless signal quality of an evolved node B. The measurement values include a first reference signal receiving quality (RSRQ) of the evolved node B. When the variation degree value is larger than the predetermined threshold value, the quality adjuster corrects the first RSRQ based on the measurement values to generate a second RSRQ of the evolved node B.

摘要： A home base station and method for supporting a plurality of cells under carrier aggregation. The home base station includes a preamble generator and a preamble monitor. The preamble generator allocates respective random access resources in the cells for handover to be carried out by a user equipment (UE), and upon receiving a handover request signal transmitted by a Mobility Management Entity (MME), generates a specific preamble and its transmission time, so that the UE performs random access on the cells based on the preamble and the transmission time to obtain the random access resources and sends out a Random Access Preamble (RAP). The preamble monitor enables the cells to simultaneously monitor the RAP sent by the UE, and when one of the cells receiving the RAP, identifies the cell on which the UE camps based on which one of the cells that has the RAP.
