Abstract: In one embodiment, a system instantiated in memory is executed by a processor to: select cells to optimize in a mobile network where the cells are associated with at least one control signal load exceeding a threshold, where the threshold is for at least one of tracking area update (TAU) load or paging load, reconfigure the cell's tracking area (TA) by either adding at least one additional cell from another TA to the cell's TA and/or removing at least one other cell from the TA, temporarily implement the reconfigured TA in the mobile network, receive updated control signal data for cells affected by said reconfigured TA, and save the reconfigured TA in the mobile network if the at least one control signal load is under the threshold and the second control signal load is under an associated second control signal load threshold for the cells affected by the reconfigured TA.

Abstract: In one embodiment, a method includes: selecting, based on control signal data, a cell to optimize in a tracking area (TA) of a mobile network, wherein the cell is associated with a control signal load that exceeds an associated control signal load threshold, wherein the load is determined according to control signal data and includes tracking area update load and/or paging load; reconfiguring the TA by: splitting the TA, combining the TA and another TA, adding another cell from another TA, and/or removing another cell; receiving, based on the reconfigured TA, updated control signal data associated with both the load and a second control signal load for cells affected by the reconfigured TA; and when the load is under the associated threshold and the second load is under an associated second control signal load threshold for the affected cells, saving the reconfigured TA for continued use in the network.

Abstract: An example method for facilitating automatic neighbor relation in a wireless telecommunication network environment is provided and includes initiating a fake handover with a target Evolved Node B (eNB) in a Long Term Evolution (LTE) wireless network environment over an S1 interface with a mobility management entity (MME), receiving a handover command message from the MME including neighbor cell information associated with the target eNB, canceling the fake handover, and updating a neighbor relations table (NRT) with the neighbor cell information. In various embodiments, the neighbor cell information includes information associated with the target eNB not communicated over an X2 interface, such as system control information communicated in a broadcast control channel. The method may further include receiving a measurement report from a user equipment with information of neighboring cells and initiating the fake handover if any neighboring cell included in the measurement report is missing from the NRT.

Abstract: Embodiments of the present disclosure include a method of resource allocation. The method includes assigning resources intended for a control channel of a mobile network to multiple resource groups. At least one resource group may include multiple resources, where the resources have at least an associated periodicity and an associated delay tolerance. The assignment may be based on the delay tolerances of the resources. The method further includes determining a composite delay tolerance of the resource groups based on the corresponding delay tolerances of the resources in the resource group. The method further includes reserving resources associated with the control channel for the resource groups based on the composite delay tolerance of the resource groups. The method further includes establishing the control channel with a user equipment (UE), where the control channel is established using the reserved resources.
