Evaluation of authentication signaling loads in 3GPP LTE/SAE networks

Abstract

The integrated core network architecture and various mobile subscriber behaviors can result in a significant increase of signaling loads inside the evolved packet core network proposed by 3GPP in Release 8. Consequently, an authentication signaling analysis can provide insights into reducing the authentication signaling loads and latency, satisfying the quality-of-experience. In this paper, we evaluate the signaling loads in the EPS architecture via analytical modeling based on the renewal process theory. The renewal process theory works well, irrespective of a specific random process (i.e. Poisson). This paper considers various subscribers patterns in terms of call arrival rate, mobility, subscribers' preference and operational policy. Numerical results are illustrated to show the interactions between the parameters and the performance metrics. The sensitivity of vertical handover performance and the effects of heavy-tail process are also discussed.Keywords-3GPP authentication and key agreement (AKA), long term evolution (LTE), evolved packet system (EPS), renewal process theory, mobile network security, performance evaluation

(U)SimMonitor: A mobile application for security evaluation of cellular networks

“…However, the computation of these performance metrics for each mobile network is not feasible, because we need access to internal network parameters that operators do not provide publicly, such as mean number of MS in each cell, number of BTS, network dimensioning, etc. To overcome this limitation, some previous works [46] [48] have estimated the performance impact of AKA by measuring the related cost and time delay of message exchanges. However, the derived numerical results of these works are theoretical, since they have used normalized values.…”

Hybrid Model to Reduce Latency in Vertical Hand Off

“…Both mobility and security strategies are not allocated the appropriate interfaces [8]. Chan-Kyu Han et al [9] reviewed the vertical handoff interoperability in evolved packet system design networks fallowed by its authentication procedures and signaling load capability. The author's permitting processes authentication randomly and make capable the authentication signals strong enough as required for the network.…”

“…But the author's ignored the necessary scenarios in vertical handoff such as mobility organization neither assigned the handoff in reactive nor proactive manner. Similarly the future of randomly authentication processes in real world implementation and its consequences on security concerns [9]. For efficient vertical handoff in different wireless networks recommended Host Identity Protocol through an incorporated design in paper [10].…”
