“…NRF can provide registration and discovery functionality to network functions, for them to discover and communicate with each other. NEF offers an interface gateway which allows external users, such as enterprises or partner operators, the ability to monitor, provision and enforce application policy such that users can be inside the operator network [188,189]. The SBA is based on the related technologies across cloud computing, virtualization, microservice, stateless service, etc.…”

The fifth generation (5G) wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized, such as mass connectivity, ultra-reliability, and guaranteed low latency. However, 5G will not meet all requirements of the future in 2030 and beyond, and sixth generation (6G) wireless communication networks are expected to provide global coverage, enhanced spectral/energy/cost efficiency, better intelligence level and security, etc. To meet these requirements, 6G networks will rely on new enabling technologies, i.e., air interface and transmission technologies and novel network architecture, such as waveform design, multiple access, channel coding schemes, multi-antenna technologies, network slicing, cell-free architecture, and cloud/fog/edge computing. Our vision on 6G is that it will have four new paradigm shifts. First, to satisfy the requirement of global coverage, 6G will not be limited to terrestrial communication networks, which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle (UAV) communication networks, thus achieving a space-air-ground-sea integrated communication network. Second, all spectra will be fully explored to further increase data rates and connection density, including the sub-6 GHz, millimeter wave (mmWave), terahertz (THz), and optical frequency bands. Third, facing the big datasets generated by the use of extremely heterogeneous networks, diverse communication scenarios, large numbers of antennas, wide bandwidths, and new service requirements, 6G networks will enable a new range of smart applications with the aid of artificial intelligence (AI) and big data technologies. Fourth, network security will have to be strengthened when developing 6G networks. This article provides a comprehensive survey of recent advances and future trends in these four aspects. Clearly, 6G with additional technical requirements beyond those of 5G will enable faster and further communications to the extent that the boundary between physical and cyber worlds disappears.

“…Each service can realize a specific functionality. Thus, microservice can enable the SBA with flexibility, granularity, and independent scaling [189]. The case study and deployment considerations about the SBA in 5G can be found in [190].…”

“…The east-bound interface (EBI) is an API for NF's MANO to interact with the service-based MEC Layer, which is mainly used to manage and orchestrate both the resource allocation and life cycle of NFs. On the basis of using the same HTTP, we design a unified Representational State Transferful (RESTful) [23] API for the SBI, NBI and EBI, which is lightweight and can be read both by people and machines easily. Thus, the service-based MEC layer provides direct communications between the NFs, the MANO and the NFs, as well as the NFs and APPs, thereby reducing the interfacecomplexity and the protocol-inconsistency in the traditional MEC architecture [18].…”

“…Added to the enhanced authentication methods for 5GC [31], the potential solutions proposed in the literature include a variety of security-and latency-aware protocols that would able to balance the contradicting requirements between security and performance for different types of services [53]. In addition to the countermeasures to better secure the communications between 5GC network functions, additional end-to-end application level security enhancements would also be needed, e.g., in roaming scenarios [54].…”

“…Web technologies are extensively used in SBAs that bring with them new inherent vulnerabilities to mobile networks. Risks of using web technologies are mainly related to availability, confidentiality, integrity and control of the mobile network functions and signalling [54]. Therefore, new solutions for securing web-based systems, such as new SBAs, are required.…”

5G enables the use of different types of services over the same physical infrastructure through the concepts and technologies of virtualization, softwarization, network slicing and cloud computing. Mobile Virtual Network Operators (MVNOs), using these concepts, provide an opportunity to share the same physical infrastructure among multiple operators. Each MVNO can have own distinct operating and support systems. However, the technologies used to enable such an environment have their own explicit security challenges and solutions. The integrated environment built upon these novel concepts and technologies, thus, will have complex security implications and requirements to be satisfied. In this vain, this article provides an overview of the security challenges and potential solutions for MVNOs.
