               1. A method of monitoring a Universal Mobile Telecommunications System (UMTS) network, the method comprising: 
            getting a recorded Radio Resource Control (RRC) message associated with a user; 
                getting recorded data indicative of cell radio resource usage in the UMTS network; 
                correlating the RRC message with the data indicative of cell radio resource usage; 
                determining a measurement quantity indicated in the RRC message; and 
                based on the measurement quantity indicated in the RRC message and the correlated data indicative of cell radio resource usage, calculating quality of a High Speed Data Packet Access (HSDPA) radio channel for the user, 
                wherein: 
              the data indicative of cell radio resource usage comprise a maximum cell transmitted power, 
                  the data indicative of cell radio resource usage comprise a ratio of power for HSDPA traffic to the maximum cell transmitted power, and 
                  the data indicative of cell radio resource usage comprise a ratio of power for other traffic than the HSDPA traffic to the maximum cell transmitted power.
