5G is the latest generation of mobile networks which will be deployed based on network softwarization concept. It will enable Local 5G Operator (L5GO) concept which is one of the most prominent versatile applications of the 5G in the near future. The unique locality features of L5GOs will be useful in many use cases such as smart cities, industrial internet and healthcare. The popularity of L5GOs will trigger more and more number of roaming and offloading opportunities between mobile users. However, existing static and the operator-assisted roaming and offloading procedures are inefficient for L5GO ecosystem. To address these challenges, we propose a blockchain / Distributed Ledger Technology (DLT) based service platform for the L5GOs to facilitate efficient roaming and offload services. We introduce several novel features, namely, universal wallet for subscribers, service quality based L5GO rating system, user-initiated roaming process and the roaming fraud prevention system. Blockchain-based smart contract scheme is proposed to establish dynamic and automated agreements between operators. A prototype of the proposed platform is emulated with the Ethereum blockchain platform and Rinkeby Testnet to evaluate the performance and justify the feasibility of the proposal.

“…via auctions, and the same approach is most widely used with the 5G spectrum release [38,39]. However, several countries have already introduced regulatory frameworks aimed at deployment of individually authorized, locally deployed private 4G or 5G networks [40]. In most cases dedicated spectrum has been released under local licensing, allowing for local network deployments through basic geographical sharing, assuming that in each location there is only one network.…”

New spectrum bands are being released to respond to the growing need for locally deployed industrial and private networks. This calls for new licensing schemes and spectrum sharing approaches. New challenges are faced from the ever-increasing variety of released spectrum bands with different technical and operational requirements and the increasing fragmentation of spectrum management approaches. While the standardization is progressing and technical solutions are developed for the new networks, less attention has been paid to the radio product related regulation, including equipment authorization frameworks. With roots in engineering, policy and economics, this paper looks through the lenses of business model framework at scenarios of wireless equipment authorization related to novel spectrum management approaches. This paper provides an overview of radio authorization for mobile communication networks and develops a conceptual framework to depict and analyze authorization policies. The results indicate the strong impact the authorization frameworks have on the scalability and replicability of the business. This calls for novel models of governance and regulation that highlight utilization of harmonized, widely employed frequency bands and the associated technical requirements.

“…Due to the fact that most of it is completely saturated, new frequency bands above 6 GHz need to be taken into consideration. Hence, it is expected that 5G NR systems will use frequency bands above 6 GHz, reaching up to 300 GHz [ 10 ]. Therefore, the main frequency spectrum to be used for 5G systems can be in licensed, shared, and unlicensed bands, see Table 1 .…”

5G is the next mobile generation, already being deployed in some countries. It is expected to revolutionize our society, having extremely high target requirements. The use of spectrum is, therefore, tremendously important, as it is a limited and expensive resource. A solution for the spectrum efficiency consists of the use of dynamic spectrum sharing, where an operator can share the spectrum between two different technologies. In this paper, we studied the concept of dynamic spectrum sharing between LTE and 5G New Radio. We presented a solution that allows operators to offer both LTE and New Radio services using the same frequency bands, although in an interleaved mode. We evaluated the performance, in terms of throughput, of a communication system using the dynamic spectrum sharing feature. The results obtained led to the conclusion that using the dynamic spectrum sharing comes with a compromise of a maximum 25% loss on throughput. Nevertheless, the decrease is not that substantial, as the mobile network operator does not need to buy an additional 15 MHz of bandwidth, using the already existing bandwidth of LTE to offer 5G services, leading to cost reduction and an increase in spectrum efficiency.
