<p>A kind of information ciphering transmission method in the wireless communication system, which includes: first, allocate the encryption pattern information separately to the base station and the transcoder and rate adapter unit TRAU in the wireless communication system; and then, when the base station need to proceed information interactive with TRAU, encrypt the information which is to be alternated with the allocated encryption pattern information between the base station and TRAU. This invention can encrypt the voice service or data service code stream which is transmitted at Abis interface in the voice service or data service processing procedure of the GSM digital cluster system, thus can prevent to look through voice service or data service at Abis interface effectively. The encryption algorithm which is selected by the invention is simple, thus, the required processing capacity of the interface bilateral baseband processing unit is low and implementation procedure's complexity unit is low and the modification to the original transaction processing is less.</p> |
