Abstract: Systems, methods and computer software are disclosed for MME load balancing. In one embodiment, a method is disclosed, comprising: processing, at an MME, at least one of: an eNodeB Identifier (ID) in a setup request; Tracking Area Code (TAC) information in a setup request which an eNodeB is supporting against a configured TAC for nodes at the MME; and historical data relating to a maximum number of subscribers the MME has attached per peer. The method further includes determining a preferred load balancing arrangement at the MME based on the processing.

Abstract: A method is disclosed for improved tracking area planning and handling, comprising: assigning a single tracking area code to a plurality of eNodeBs at a messaging concentrator gateway, the messaging concentrator gateway situated in a network between the plurality of eNodeBs and the core network; storing, at the messaging concentrator gateway, at least one indicator of a last known location of a user equipment (UE) other than the single tracking area code; receiving a paging message from the core network at the messaging concentrator gateway for a UE; and performing a paging sequence using the at least one indicator to identify a set of eNodeBs to page the UE, thereby allowing larger tracking area list sizes to be used without increasing signaling traffic between the radio access network and the core network.

Abstract: Systems and methods are disclosed for enabling a mesh network node to switch from a base station role to a user equipment role relative to a second mesh network node, and vice versa. By switching roles in this manner, the mesh network node may be able to benefit from increased uplink or downlink speed in the new role. This role reversal technique is particularly useful when using wireless protocols such as LTE that are asymmetric and allow differing throughput on uplink and downlink connections. Methods for determining whether to perform role reversal are disclosed, and methods for using role reversal in mesh networks comprising greater than two nodes are also disclosed.
