A tracking area, TA, optimization system comprising: a processor; a memory; and a TA optimization manager application, instantiated in said memory and configured to be executed by said processor to at least: use control signal data to select at least one cell to optimize in a TA of a mobile network, wherein said at least one cell is associated with at least one control signal load that exceeds an associated control signal load threshold, wherein said at least one control signal load is determined according to said control signal data, and is at least one of tracking area update, TAU, load or paging load, reconfigure said TA to form a reconfigured TA by at least one of: adding at least one additional cell from another TA to said TA, or removing at least one other cell from said TA, temporarily implement said reconfigured TA in said mobile network, for a configurable period of time, receive updated control signal data associated with both said at least one control signal load and a second control signal load for cells affected by said reconfigured TA, and upon determining according to said updated control signal data that said at least one control signal load is under said associated control signal load threshold and that said second control signal load is under an associated second control signal load threshold for said cells affected by said reconfigured TA, save said reconfigured TA for continued use in said mobile network. a processor; a memory; and a TA optimization manager application, instantiated in said memory and configured to be executed by said processor to at least: use control signal data to select at least one cell to optimize in a TA of a mobile network, wherein said at least one cell is associated with at least one control signal load that exceeds an associated control signal load threshold, wherein said at least one control signal load is determined according to said control signal data, and is at least one of tracking area update, TAU, load or paging load, reconfigure said TA to form a reconfigured TA by at least one of: adding at least one additional cell from another TA to said TA, or removing at least one other cell from said TA, temporarily implement said reconfigured TA in said mobile network, for a configurable period of time, receive updated control signal data associated with both said at least one control signal load and a second control signal load for cells affected by said reconfigured TA, and upon determining according to said updated control signal data that said at least one control signal load is under said associated control signal load threshold and that said second control signal load is under an associated second control signal load threshold for said cells affected by said reconfigured TA, save said reconfigured TA for continued use in said mobile network. use control signal data to select at least one cell to optimize in a TA of a mobile network, wherein said at least one cell is associated with at least one control signal load that exceeds an associated control signal load threshold, wherein said at least one control signal load is determined according to said control signal data, and is at least one of tracking area update, TAU, load or paging load, reconfigure said TA to form a reconfigured TA by at least one of: adding at least one additional cell from another TA to said TA, or removing at least one other cell from said TA, temporarily implement said reconfigured TA in said mobile network, for a configurable period of time, receive updated control signal data associated with both said at least one control signal load and a second control signal load for cells affected by said reconfigured TA, and upon determining according to said updated control signal data that said at least one control signal load is under said associated control signal load threshold and that said second control signal load is under an associated second control signal load threshold for said cells affected by said reconfigured TA, save said reconfigured TA for continued use in said mobile network.
