Controlling telecommunications channel switching

摘要

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.

主权项

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, and 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 a decision not to switch the radio resource control state.
