“…A relative velocity-based DoM prediction mechanism for UE is used. The novel mechanism of LoP estimation of an eNB battery backup is also used in this work [2]. In an LTE-A network, an UE may receive the LoP information of the different NeNBs from the SeNB either as an added field in the existing Handover Measurement Control Request message or as an emergency broadcasted information service similar to the newly introduced 3GPP Earthquake and Tsunami Warning Service (ETWS) and Commercial Mobile Alert Service (CMAS) [11][12].…”

“…This dynamic allocation of weights based on the underlying environment is more realistic than allocating fixed weights and changing them manually as proposed in [2], where we have assigned some non-zero weights to S LoP even during the normal non-disaster situations. The parameter LoP is relevant and meaningful only at the time of natural disaster.…”

“…The UE assigns scores to each NeNB against these two parameters and finally selects the TeNB based on the highest weighted average score (WAS). This work is an extension to our previous work published in [2]. The proposed scheme aims at discouraging the arrival of new traffic/calls to an already overloaded natural disaster affected eNB in order to prolong the overall lifetime of the battery backup in the eNBs.…”

“…They are expected to be stable and reliable always. However, natural disasters, like earthquakes and hurricanes, may damage the whole network infrastructure or cause breakdown of the power grid in the affected areas hampering telecommunication services [1][2]. Immediately after a natural disaster the telecommunication networks become heavily congested as a result of sudden and huge increase in network traffic/calls in the affected areas.…”

“…This in turn would prolong the flow of the number of voice calls and text messages immediately after a disaster situation by utilizing the LoP of the backup batteries before they die down. We used a relative velocity-based DoM prediction algorithm which is different to the angle-of-divergence based prediction method used in [2]. We also propose a novel mechanism of an UE self-detecting the natural disaster situation and dynamically adjusting the weighted values of the DoM and LoP.…”

Abstract-Telecommunication networks often face power outage problems in the natural disaster affected areas. Also, owing to a sudden substantial increase in network traffic loads the battery backup power of the base stations run out quickly and therefore hampering telecommunication services. To overcome this system performance issues, we propose a Long Term Evolution (LTE)-Advanced (LTE-A)-based user equipment (UE)-controlled and base station (Evolved Node B or eNB)-assisted handover scheme. The idea is to limit the arrival of new traffic to an already overloaded eNB by diverting their handover to lightly loaded nearby eNBs. The novelty of this work is the ability of an UE to self-detect the occurrence of a natural disaster and to self-select the most suitable target eNB (TeNB) to handover with in the disaster affected areas. The handover is performed by obtaining the weighted average score (WAS) of the direction of motion (DoM) and the leftover battery backup power of the different neighboring eNBs (NeNB). The UE also predicts its DoM and dynamically adjust the weights of the two parameters if it's a disaster situation. Preliminary simulation results show that the scheme can offer up to 65% handover success rate in disaster situations.Keywords-natural disaster, seamless handover, leftover power, base station, LTE-A, weighted average score, movement prediction
