“…An important issue to consider is that the inter-list handover resides on three factors: UEs, probability of the user to move between cells, and the cost of inter-MME. A careful look at the aforementioned discussion reveals a bottleneck effect between the total signaling cost of TAU and paging from one side, and the total cost of the inter-list handover from the other side [5,6]. Thus, the location management addressed in this work is NP-hard, and locating approximate solution is NP-hard.…”

“…The main difference between centralized scheme and distributed one is the method of calculating TAU. According to the result of comparison between the two schemes, distributed scheme requires extra signal load from MME relocation, thus, it can be stated that centralized scheme is more efficient than the distributed scheme [5,6]. Therefore, the problem considered in this section utilizes a centralized MME pooling scheme [5,14].…”

“…In addition, the authors proposed another study with lower complex linear programming model that follows the concept of previous approach for minimizing the signaling load . Two studies in Aqeeli et al discussed the TAU and paging signaling overhead with regards to TAL construction with the perspective of relating the management mobility entity with TAL. Both the studies proposed a centralized and a distributed MME scheme.…”

“…The objective of this study is to minimize the total signaling overhead caused by paging and TAU. Two studies have been proposed earlier which implement various methods to minimize the total overhead. The first study is to minimize the overhead gain by using two pooling schemes namely; centralized and distributed.…”
