Abstract

5G cellular networks will enable new differentiated services and applications to support industry like healthcare, energy, automobile and security. These services will massively increase the number of attached devices like mobiles, sensors, and actuators, resulting in sharp increase in mobile traffic volume. To cater high traffic volume and to fulfill strict quality of service requirements, 5G networks are expected to handle complex scenarios to provide seamless mobility and better resource utilization. In this paper, we propose mobility management algorithm for target cell selection and provide a methodology to evaluate its performance under varying conditions in mmWave framework. We use discrete timeMarkov chain (DTMC) andMarkov decision process (MDP) to model radio access network controller and user equipment respectively. Probabilistic model checking (PMC) is used to do performance evaluation of the algorithm. The results show that our proposed algorithms adapts to network changes and responds successfully to mobility management process execution. With the help of PMC, we also gain useful insights regarding critical network parameters which can be used to achieve optimal resource utilization and to enhance user perceived quality of service (QoS).

5G
In telecommunications, 5G is the fifth-generation technology standard for broadband cellular networks, which cellular phone companies began deploying worldwide in 2019, and is the planned successor to the 4G networks which provide connectivity to most current cellphones. Like its predecessors, 5G networks are cellular networks, in which the service area is divided into small geographical areas called cells. All 5G wireless devices in a cell are connected to the Internet and telephone network by radio waves through a local antenna in the cell.
2G
2G is a short notation for second-generation cellular network, a group of technology standards employed for cellular networks. 2G was commercially launched on the GSM standard in Finland by Radiolinja (now part of Elisa Oyj) in 1991. After 2G was launched, the previous mobile wireless network systems were retroactively dubbed 1G. While radio signals on 1G networks are analog, radio signals on 2G networks are digital, though both systems use digital signaling to connect cellular radio towers to the rest of the mobile network system.
Cellular network
A cellular network or mobile network is a telecommunications network where the link to and from end nodes is wireless and the network is distributed over land areas called cells, each served by at least one fixed-location transceiver (typically three cell sites or base transceiver stations). These base stations provide the cell with the network coverage which can be used for transmission of voice, data, and other types of content.
