Executive summary This work item focuses on using Identity Oriented Networks (ION) for next generation architectures toward 5G and be

21、yond. The basic concept and goal behind ION is to dissociate the identifier and temporal location information for an entity. Ideally, this goal should endeavour for deployment to support current architectures while also enabling more optimal future architectures. The work aims to examine and propose

22、 recommendations to improve and simplify the network infrastructure to support mobility natively by adopting ION. In addition, the work item may require the development of new protocols and/or modification of existing protocols. ETSI ETSI GR NGP 004 V1.1.1 (2018-01) 6 Introduction The Internet is se

23、minal for communication technologies and is a powerful enabler for modern applications with connectivity needs. However, when the Internet was designed the requirements were wildly different from the applications to be enabled by 5G infrastructure. Forty years ago, no one expected the user behaviour

24、 to evolve from text based fixed Internet access to streaming 4K quality media over a mobile device with session continuity. Mobility support is today the norm and new solutions should be examined for the network to support these new capabilities. As the Internet is pervasive and therefore these sol

25、utions should still interoperate with the current architecture. Today the users expectation and experience is at the forefront driving the requirements of applications such as session continuity, augmented reality, virtual reality or high definition video. Most importantly perhaps, the future deploy

26、ment of 5G gives a unique opportunity to examine how core technologies may be modified, enhanced or replaced for a more secure, robust and optimized architecture for the future mobile networks. With this in focus, the present document reviews the current state-of-art of Identity-oriented solutions (

27、ION), and provides recommendations toward new protocols and/or modification of existing ones in the context of ION.

44、 Network 4 Identity Oriented Networks (IONs): Architecture Overview 4.1 Introduction The current Internet architecture, which has been built with and on top of the Internet Protocol (IP), was designed for a very different environment from modern networks. Early versions of the Internet Protocol were

45、 designed in the 1970s. The Internet protocol architecture has evolved over time since then, largely as a result of the Internet Engineering Task Force (IETF) organization. However, the landscape of networks has changed dramatically and many of the initial Internet architecture tenets have changed t

46、oo. As an example of one of these dramatic Internet architectural changes, today many Internet references cite that 70 % of the access sessions setup towards it are originated on a mobile device. However, at the start of the Internet design, the notion of mobility was not even considered. Today, mob

47、ility is a major Internet requirement, and the number of users operating mobile devices has exploded, overtaking the number of fixed PC connections in 2014 i.1. According to reference i.2, the projected growth of mobile devices is 1,5 per person, reaching a staggering total number of 11,6 billion co

48、nnections by 2020. To cement a more near-term understanding of this trend, that global mobile data traffic has increased by 74 % in 2015 (according to reference i.2). Indeed, ubiquitous mobility is the norm and here to stay. It is also very important to highlight that both the definition of mobility

49、 and its correlated requirements in the networks have drastically changed over time. For instance, in order to transit from LTE to 5G, the network requirements have become more stringent with respect to KPIs for latency, reliability, throughput, etc. i.20. This increase, in conjunction with evolving user beha
