Method for controlling measurements in a wireless telecommunications terminal

A method for controlling measurement procedures in a telecommunications terminal affiliated to a wireless telecommunications network, the method comprising:

• receiving measurement configuration data, including measurement reporting criteria, from the wireless telecommunications network at a Radio Resource Control (RRC) layer of said telecommunications terminal;
• communicating the measurement configuration data and the measurement reporting criteria from said RRC layer to a physical layer of the telecommunications terminal;
• performing a measurement given by the measurement configuration data at the physical layer of the terminal;
• evaluating results of the measurement with the measurement reporting criteria at the physical layer of the telecommunications terminal to provide evaluation results;
• controlling said RRC layer from the physical layer to go into or remain in a power save mode if the evaluation results do not trigger a measurement result report to the wireless telecommunications network;
• controlling said RRC layer from the physical layer to exit the power save mode to report the measurement if the evaluation results of the measurement trigger the measurement result report to the wireless telecommunications network;
• wherein the communicating at least a part of said measurement configuration data from said RRC layer to said physical layer comprises communicating a first message that contains RRC information elements which are the same for all carrier frequencies, and communicating a second message that contains RRC information elements specific for each carrier frequency;
• and
• wherein said RRC information elements included in the first message define at least a measurement gap configuration, a signal strength threshold for a serving cell, and a measurement quantity configuration for performing layer 3 filtering.

• wherein the physical layer uses a third message to direct the RRC layer to go off the power save mode when a reporting criterion of the measurement reporting criteria is fulfilled;
• and
• wherein the physical layer informs the RRC layer when a Reference Signal Received Power (RSRP) of a serving cell gets worse than a signal strength threshold using said third message.
