“…Under the proposed policy, the TAL can have any number of TAs; as a result, it is possible to easily implement the proposed TbRcc1c in any real network architecture. The results of this study can be used in research on the mobility management of next-generation networks [8][9][10], as well as LTE networks. In further study, the 5G-related matters will be investigated to implement the proposed method in 5G network.…”

LTE networks consist of tracking areas (TAs) or a group of cells, while several TAs constitute a TA list (TAL). The LTE network adopts TAL-based registration, where, if the user equipment (UE) enters a TA that is not in its current TAL, the UE registers the TA to inform the network of its new location. A central policy for TAL allocation, known as a TA-based central policy, was proposed for TAL-based registration. Under the central policy, the TA in which the UE registers its location becomes the central TA of the new TAL. This policy can lessen the possibility of the UE quickly exiting the new TAL. However, considering the actual network architecture, it makes TAL-based registration a challenge to implement. Thus to mitigate this problem, a cell-based central policy is proposed. This study investigates TAL-based registration with cell-based central policy (TbRcc) for LTE networks. TAL-based registration with cell-based central policy and single-cell TA (TbRcc1c) is also proposed to reduce the registration cost and make up the optimal TAL. Furthermore, an improved analysis model is presented to reflect the effect of the implicit registration of calls and obtain the exact cost. Comparing the performance of the proposed scheme with those of classical TAL-based registration and distance-based registration, the performance of the proposed scheme is shown to improve. The results of this study can help research that addresses the mobility management of next-generation networks, as well as LTE networks.

“…In addition, some paging schemes for TAL-based mobility management Fig. 1 TA and TAL in the LTE network have been proposed [6,7], and research results on how to apply TAL-based registration to not only 4G, but also 5G, have recently been presented [8][9][10]. However, because of their complex procedure, these were difficult to implement.…”

“…In addition to the UABS concept, also known in the literature as UAV-assisted wireless communications [77], the use of UAVs in combination with 5G has found numerous other promising applications for PPDR that extend their use into areas such as monitoring and remote sensing of locations of interest by means of live video feeds, imagery and sensor data gathering and analysis, search and rescue missions, as well as transportation and logistics support, e.g. delivery of equipment and medical supplies to inaccessible areas [30], [59], [78], [79]. Commonly referred to as cellular-connected UAVs [77], in these applications the UAVs are considered new aerial users acting in the context of PPDR usage scenarios.…”

Today, legacy PMRs continue to be the only group of tested, verified and certified technologies for the Public Protection and Disaster Relief (PPDR) sector. For the fifth generation (5G) to follow suit, substantial hands-on experimentation with functional, architectural and deployment aspects is required, and further test trials need to take place in order to inform and enable future verification and certification procedures for 5G to become a proven PPDR technology. This paper studies 5G PPDR experimentation associated with novel virtualized and cloud-native 5G technologies, architectures and deployment options, as well as feasibility studies and field performance and verifications trials involving vertical-specific 5G infrastructures and applications. Key enabling technologies, such as massive multiple input multiple output (MIMO), device-to-device (D2D), network slicing and multi-access edge computing (MEC) are discussed and 5G PPDR architecture and deployment options are investigated. A dedicated 5G PPDR experimentation facility is presented, and a case study of hands-on experimentation is provided. Two distinct scenarios are discussed, i.e., emergency augmentation of the terrestrial 5G PPDR network with rapidly deployable on-site capacities in the area of a public safety incident, and availability and reliability of decision-support PPDR applications on the field. Experience with the deployment and verification insights are accompanied by the results of quality of service (QoS) and non-functional key performance indicators (KPI) assessment that were exhibited during the experiment. The experimentation outcomes confirm the ability of the facility to support emulated laboratory experimentation specifically designed to tackle 5G challenges for this particular vertical as well as field studies recreating realistic public safety operations.INDEX TERMS 5G, mobile communications, public safety, public protection and disaster relief, mission critical communications, network architecture, network deployment, experimentation, field trial.

“…Firstly, ABSs provide the system with advantages, such as swift deployment and high line-of-sight (LOS) communication probability. They are of great help when building a communication network in temporary situations or specific scenes, such as during rapid network recovery and in dense communication user networks [ 9 , 10 ]. Further, with the ability to fly directly over the users, the LOS communication probability increases and, therefore, communication stability is improved [ 11 ].…”

The future development of communication systems will create a great demand for the internet of things (IOT), where the overall control of all IOT nodes will become an important problem. Considering the essential issues of miniaturization and energy conservation, in this study, a new data downlink system is designed in which all IOT nodes harvest energy first and then receive data. To avoid the unsolvable problem of pre-locating all positions of vast IOT nodes, a device called the power and data beacon (PDB) is proposed. This acts as a relay station for energy and data. In addition, we model future scenes in which a communication system is assisted by unmanned aerial vehicles (UAVs), large intelligent surfaces (LISs), and PDBs. In this paper, we propose and solve the problem of determining the optimal flight trajectory to reach the minimum energy consumption or minimum time consumption. Four future feasible scenes are analyzed and then the optimization problems are solved based on numerical algorithms. Simulation results show that there are significant performance improvements in energy/time with the deployment of LISs and reasonable UAV trajectory planning.
