System and method for managing frequency layer priority assignments within mobile wireless network radio interfaces
A method and system are described for managing radio frequency layer priority settings for radio access network nodes in a mobile wireless network. A programmed server is configured with an initial configuration of the trigger definitions and corresponding radio frequency layer priority settings. Thereafter, the programmed server applies current conditions bearing upon a conditional area to a conditional area trigger definition. The programmed server then issues, based upon the application of the current conditions to the conditional area trigger definition, a message to re-designate radio frequency layer priority settings for a cell. The programmed server thereafter receives network characteristics feedback.
1. A method, carried out by a programmed server, for managing radio frequency layer priority settings for radio access network nodes in a mobile wireless network supporting multiple radio frequency layers corresponding to particular radio frequency bands with each frequency band being sub-divided into multiple channels, the method comprising:
providing the programmed server with a radio frequency layer priority settings re-designation configuration for a ranked set of condition areas, the configuration including, for each one of the ranked set of conditional areas;
a set of radio frequency layer priority settings, and
a trigger definition for assigning the set of radio frequency layer priority settings to a radio access network node;
evaluating, by the programmed server, the trigger definition for at least one of the ranked set of conditional areas based upon current conditions;
issuing, by the programmed server based upon the current conditions meeting the trigger definition for at least one of the ranked set of conditional areas during the evaluating, a message to re-designate radio frequency layer priority settings for a radio access network node according to the set of radio frequency layer priority settings of a highest ranked conditional area for which the current conditions meet the trigger definition; and
receiving, by the programmed server after the issuing, network characteristics feedback.
2. The method of claim 1 further comprising:
determining, based upon the network characteristics feedback, whether the network characteristics improved after the issuing.
3. The method of claim 2 further comprising:
reverting, based upon the determining, back to previous radio frequency layer priority settings.
4. The method of claim 3 further comprising:
temporarily disabling, based upon the determining, applying current conditions bearing upon the conditional area to the trigger definition.

8. The method of claim 1 wherein the trigger definition comprises whether a radio access network node layer, to which the trigger definition applies, supports user equipment applications requesting services associated with a particular standard version.
9. The method of claim 1 wherein the radio frequency layer priority settings are specified, by the programmed server, on a cell level of granularity.
10. The method of claim 1 wherein the radio access network node is an eNodeB cell.
