Abstract— The enormous competition and the increasing number of user equipment (UE) in the telecommunications market has
garnered attention towards the necessity of optimized and cost-efficient networks. Tracking the position of UEs while minimizing
signalling cost is a key problem that needs to be solved for upcoming 5G networks. Tracking area (TA) is a term used for
assemblage of cells (nodes) in long term evolution networks. Planned distribution of TAs, depending on the mobility pattern of
UEs, is a technique used to optimize the signalling overhead, and plays a vital role in utilizing the resources efficiently. TAs must
be reconfigured over the time intervals so as to adapt them to the variation in UE's pattern. Compared to earlier generations of
cellular networks, 5G networks will have more flexible configuration of TAs as it will utilize the concept of tracking area list, given
in 3GPP release 8. One of the objectives of 5G mobile network is to cope up with an ever-increasing number of UEs. This paper
forms a basis for TA reconfiguration in 5G network using game theory, and finds an optimal solution for optimizing the signalling
overhead of the network.
