Patent ID: 7580527

Claim:
A system for communicating monitoring in a mobile radio network comprising: a processing device coupled to multiple links in the mobile radio network, the processing device (i) determining from data transferred via the multiple links current deciphering parameters and (ii) deciphering the data using the current deciphering parameters to produce deciphered data; a deciphering parameter providing device coupled to the processing device in which the current deciphering parameters are filed by the processing device to be available for another processing device upon request; a deciphered data providing device coupled to the processing device for providing the deciphered data at an output for protocol analysis, or procedure trace to be performed on deciphered data; wherein the processing device, deciphering parameter providing device and deciphered data providing device are distributed over different locations and are coupled together by a communication link; wherein the data includes both unciphered and ciphered data and the processing device comprises: means for deciphering the ciphered data according to the current deciphering parameters; and means for combining the unciphered data and the deciphered ciphered data to produce an ordered data flow as the deciphered data; wherein the combining means comprises a delay device for delaying the unciphered data while the deciphering means deciphers the ciphered data so the deciphered data is in the ordered data flow with the unciphered data.
