移动管理解决方案是否已为5G及更高版本做好准备?

Are Mobility Management Solutions Ready for 5G and Beyond?

Akshay Jain, Elena Lopez-Aguilera, Ilker Demirkol

摘要:

使用户能够移动到网络中的不同地理位置,并且仍然能够保持其连接性,最重要的是,保持服务的连续性,这使得任何无线网络无处不在。虽然具有挑战性,但是现代无线网络(诸如3GPP-LTE)提供令人满意的移动性管理(MM)性能。然而,据估计,移动用户数量将在2024年达到约90亿,数据流量将比2018年增加5倍。此外,预计这种指数增长的趋势将在未来很长一段时间内保持下去。为了应对蜂窝业务和用户的这种指数增长以及对更高服务质量(QoS)的迅速增长的需求,未来的网络被期望是高度密集和异构的。这将严重挑战现有的MM解决方案,并最终使其无效,因为它们将无法提供所需的可靠性,灵活性和可扩展性。因此,为了服务于5G和超越5G的网络,需要MM的新视角。因此,在这篇文章中,我们提出了一个新的讨论这些网络的MM策略的功能要求。我们提出了一种新的定性评估的国家的最先进的机制的基础上,他们的能力,以满足未来的MM策略的可靠性,灵活性和可扩展性的标准。然后,我们提出了一项研究,详细介绍了在设计和实施5G及以上网络的MM策略中存在的研究挑战。此外,我们还列出了潜在的MM解决方案及其提供的相关功能,以应对持续的挑战。最后,我们对5G及以后的MM机制进行了展望。

英文摘要:

Enabling users to move to different geographical locations within a network and still be able to maintain their connectivity and most essentially, continuity of service, is what makes any wireless network ubiquitous. Whilst challenging, modern day wireless networks, such as 3GPP-LTE, provision satisfactory mobility management (MM) performance. However, it is estimated that the number of mobile subscriptions will approximately touch 9 billion and the amount of data traffic will expand by 5 times in 2024 as compared to 2018. Further, it is expected that this trend of exponential growth will be maintained well into the future. To cope with such an exponential increase in cellular traffic and users alongside a burgeoning demand for higher Quality of Service (QoS), the future networks are expected to be highly dense and heterogeneous. This will severely challenge the existing MM solutions and ultimately render them ineffective as they will not be able to provide the required reliability, flexibility, and scalability. Consequently, to serve the 5G and beyond 5G networks, a new perspective to MM is required. Hence, in this article we present a novel discussion of the functional requirements from MM strategies for these networks. We present a novel qualitative assessment of the state-of-the-art mechanisms based on their ability to satisfy the reliability, flexibility and scalability criteria for future MM strategies. We then present a study detailing the research challenges that exist in the design and implementation of MM strategies for 5G and beyond networks. Further, we chart out the potential MM solutions and the associated capabilities they offer to tackle the persistent challenges. We conclude this paper with a vision for the 5G and beyond MM mechanisms.
