1. A system for implementation in a base station for selective location-based activation of channel quality indication (CQI) reporting by mobile terminals in a wireless communication network, the system comprising:
a user equipment (UE) location monitor to detect a present physical location of a mobile terminal of a plurality of user equipment (UE) devices in communication with the base station, each of the plurality of UE devices configured to be toggled by the base station into either of an active CQI reporting mode or an inactive CQI reporting mode;
a mapping database having, stored thereon, a plurality of location-mapped CQI entries, each being a mapping between a respective CQI reporting location and a respective CQI score generated from respective CQI information previously reported by one or more UE devices while in the respective CQI reporting location;
a CQI reporting controller coupled with the UE location monitor and the mapping database to:
match the present physical location to a particular location-mapped CQI entry of the plurality of location-mapped CQI entries;
determine whether the respective CQI score of the particular location-mapped CQI entry is stale;
communicate a control message to the mobile terminal to toggle the mobile terminal to the active CQI reporting mode in response to the staleness detector determining that the respective CQI score of the particular location-mapped CQI entry is stale; and
receive a CQI reporting message from the mobile terminal, responsive to the mobile terminal toggling to the active CQI reporting mode, the CQI message indicating a present spectral efficiency experienced by the mobile terminal at the present physical location.
