Controlling telecommunications channel switching
First Claim
1. A method of operating a node of a radio access network which controls transitions between radio resource control states for a wireless terminal, the method comprising the acts of:
- (1) upon a completion of a data activity, making a prediction of a data transmission parameter, the data activity being a transfer of data between the wireless terminal and the node;
(2) making an assessment regarding probable accuracy of the prediction; and
(3) using the assessment to make a determination whether or not to implement a radio resource control state switch,wherein making the assessment comprises determining that the probable accuracy of the prediction exceeds an accuracy threshold, andwherein the accuracy threshold is selected based on one or both of a weighted cost of erroneously making a decision to switch the radio resource control state, and a weighted cost of erroneously making a decision not to switch the radio resource control state.

Abstract
A node (26) of a radio access network (24) and method of operating such node controls transitions between radio resource control states for a wireless terminal (30). In an example embodiment and mode the method comprises: (1) upon completion of a data activity, making a prediction of a data transmission parameter; (2) making an assessment regarding probable accuracy of the prediction; and (3) using the assessment to make a determination whether or not to implement a radio resource control state switch (the “state switch”). The data transmission parameter may be a different parameter in respective differing example embodiments. In one example embodiment and mode the data transmission parameter comprises inter-arrival time between bursts of data activity. In another example embodiment and mode the data transmission parameter comprises burst size of a burst of data activity.

9. A node of a radio access network which controls transitions between radio resource control states for a wireless terminal, the node comprising:
-
a radio resource manager configured to; (1) make a prediction of a data transmission parameter upon a completion of a data activity, the data activity being a transfer of data between the wireless terminal and the node; (2) make an assessment regarding probable accuracy of the prediction determining that the probable accuracy exceeds an accuracy threshold; (3) use the assessment to make a determination whether or not to implement a radio resource control state switch; and a communications interface through which the node notifies the wireless terminal whether or not to implement the state switch, wherein the accuracy threshold is selected based on one or both of a weighted cost of erroneously making a decision to switch the radio resource control state, and a weighted cost of erroneously making decision not to switch the radio control state. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method of operating a node of a radio access network configured to control radio resource control (RRC) states for a wireless terminal, the method comprising:
-
making, by the node, a prediction of a data transmission parameter upon a completion of a data activity associated with a wireless terminal, the data activity being a transfer of data between the wireless terminal and the node; making, by the node, an assessment of an accuracy of the prediction by determining whether or not the probable accuracy of the prediction exceeds an accuracy threshold; determining, by the node, whether a state switch should be implemented based on the assessment, the state switch comprising switching of the RRC state of the wireless terminal to a lower state; and implementing, by the node, the state switch when it is determined that the state switch should be implemented based on the assessment, wherein the accuracy threshold is set in relation to a cost of making an erroneous prediction such that higher accuracy threshold correlates to higher cost of the erroneous prediction. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)
