Disclosed are a building baseband unit, a baseband processing panel, and a failure processing method for the baseband processing panel. A direct path is introduced respectively for a baseband processing module and a power supply module in a baseband processing panel; when the baseband processing module has failed, the baseband processing module is directly bypassed, and a part of the baseband processing resources of a baseband processing panel in normal operation is allocated to an RRU corresponding to the failed baseband processing panel via a back panel and the direct path; and when both the baseband processing module and the power supply module have failed, both of them are directly bypassed, and a part of the baseband processing resources of a baseband processing panel in normal operation is allocated to the RRU corresponding to the failed baseband processing panel via the back panel and the direct path, and at the same time the power required for working is provided to an optical module via the back panel and another direct path. Applying the solution of the present invention can reduce implementation costs.

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.

The present invention provides a method, a device, a network element and a system for-switching a network. The method may include: obtaining, through a first network that a terminal accesses, a message required by a preparation process before the terminal switches to a second network; alternating with the second network according to the message, after the preparation process before the switching is completed, releasing a first connection so as to make the terminal directly establish a connection to the second network after releasing the first connection channel. According to the solution of the present invention, the problem of interference generated when two networks switch is avoided.
