摘要： A method using drive test data for propagation model calibration includes: step 1, obtaining original drive test data; step 2, selecting the data from the drive test data according to predefined conditions as effective drive test data; and step 3, extracting the effective drive test data to form a data file used for propagation model calibration. An apparatus using drive test data for propagation model calibration includes: a drive test data obtaining module, configured to obtain the drive test data in the regions to be calibrated; an effective drive test data generation module, configured to generate effective drive test data from the drive test data according to predefined conditions; and a data file generation module, configured to extract the effective drive test data to form a data file used for propagation model calibration. The present invention utilizes drive test data of existing networks to largely decrease the CW test work and reduce the network building cost. It is believed that the calibrated model can relatively accurately reflect the propagation characteristics in the field. Furthermore, base stations can be optimally allocated.

摘要： Switched-beam antenna arrangement means use a method of controlling an antenna pattern of such antenna arrangement means. Each antenna pattern of a predetermined number of fixed antenna patterns is allocated to a predetermined time slot of a time multiplexed signal. The switched-beam antenna arrangement means is switched to generate the fixed antenna patterns during their allocated time slots. Thereby, any user can choose between distinct beam patterns by selecting an appropriate time slot, so that the risk that the user is located at the intersection area of two beams is greatly reduced.
