A mobile device and method for predictive computing of variable mobile link parameters per session and state in a future time interval within Radio Access Networks (RAN). The system narrows its prediction errors as time progresses. An ideal control value is also estimated, so that mobile QoS applications can determine their intervention point while coexisting with link layer resource management mechanisms. The system is provided with certain measurement elements from the RAN. With the information contained in these elements, the system estimates the Received Signal Strength (RSSI), Received Wideband Power (RSCP), Signal Interference Ratio (SIR), Bit Error Rate (BER), the transmission delay per frame (delay), the variation between delay measurements throughout a certain number of measurement time frames and the mean bit throughput rate (Chip Rate) for a future time interval. The system also calculates the optimal power control (gain) for a defined value target of a given link parameter. The estimates are passed on to other Systems for further processing.
