Abstract
Mobile cellular networks are an indispensable part of modern life, where the need for customer satisfaction in the use of many different services by consumers is constantly increasing. The requirements for higher transmission speed, lossless transmission, reliability, efficiency, low latency, mass connectivity, guarantee of high Quality of Service criteria are repeatedly increasing. All this requires the continuous development of the used technologies as well as the introduction of new generations of networks. Handover mechanism is extremely important in cellular network because of the cellular architecture employed to maximize spectrum utilization. To ensure the quality of service in wireless cellular networks, the report proposes the use of a Horizontal Handoff Priority Scheme. Simulation experiments have been carried out, the probability parameters of the scheme have been evaluated and the probabilities of losses occurrence have been classified as rare events. The proposed material are various algorithms and techniques for the implementation of Vertical and Horizontal Handoff in 3G, 4G and fifth-generation networks to provide the required QoS for mobile users with Ultra-High Definition.
Highlights
Mobile cellular networks are an integral part of modern life
Qos probability parameters are found to be less than 10-8, they are classified as rare events
The challenge for new mobile networks is the provision of a wide range of applications and services with many different technologies, in parallel with different Quality of Service (QoS) requirements
Summary
In order to ensure high levels of consumer satisfaction, the requirements for high speed, reliability and efficiency, low latency and performance, energy savings, mass connectivity, lossless transmission and Quality of Service (QoS) guarantee are repeatedly increased. All this leads to the need for continuous development and improvement of the technologies used and the introduction of new generations of networks. The challenge for all networks is data transmission to be carried out without loss [3, 12] For these reasons, in order to meet the QoS criteria, it is necessary to classify losses as rare events. These events are described in the literature as events with a probability of occurrence much smaller than 10-6 [3, 4]
