Patent ID: 8611832

Claim:
A method implemented in a mobile telecommunication network of selecting an antenna mode to be used for communication between a radio network and a mobile terminal operating in discontinuous reception mode, comprising: determining a mode list comprising antenna modes that are supported by both the radio network and the mobile terminal; associating each antenna mode in the mode list with a degree of a pre-defined performance measure; and while the mobile terminal is operating in discontinuous reception mode: dynamically retrieving information indicating a degree of the pre-defined performance measure currently provided for the mobile terminal by a currently selected antenna mode; dynamically tracking which, if any, antenna mode in the mode list is associated with a degree of the pre-defined performance measure that is better than the degree indicated by the retrieved information; and if an antenna mode is tracked as being associated with a better degree of the pre-defined performance measure than the currently selected antenna mode, dynamically switching as needed from the currently selected antenna mode to that antenna mode.
