Abstract:
1. A method for controlling pilot power of a Home NodeB (HNB), comprising: initializing the HNB and setting up communication connection between the HNB and a mobile terminal user, and further comprising: determining a setting type of a current data communication service; determining whether a current SNR is more than or equal to a predetermined threshold and obtaining a determining result according to the determining of the setting type when the current data communication service is of a first type or a second type, increasing current pilot power when the current data communication service is of the first type and the current Signal-to-Noise Ratio (SNR) is less than a predetermined threshold; and reducing the current pilot power when the current data communication service is of the second type and the current SNR is more than or equal to the predetermined threshold, wherein whether the current data communication service is set as the first type or the second type is dependent on an amount of resources occupied by the current data communication service or a QoS evaluation value, wherein the current pilot power is recovered to an initial value when the communication connection between the HNB and the mobile terminal user is completed, wherein the current pilot power is kept at the initial value when the current data communication service is of the first type and the current SNR is more than or equal to the predetermined threshold or when the current data communication service is of the second type and the current SNR is less than the predetermined threshold.
