1. A method for reducing the power consumption of a user terminal in a communication network, said method being performed in a data communication emulating unit located in the user terminal or in a proxy device of the communication network and comprising the steps of: monitoring communication between an application unit in the user terminal and a proxy unit in the proxy device, said communication employing requests and responses based on a data communication protocol, determining a communication pattern of the monitored communication, evaluating if the communication is efficient or not based on the communication pattern, and changing communication strategy if the communication pattern is found to be inefficient through performing the further steps of disrupting communication between the application unit and the proxy unit using the data communication protocol and enabling communication between the proxy unit and application unit based on a signalling protocol.
