GARANTIA DE QUALIDADE DE SERVIÇO COM 5G PRIORIZANDO APLICAÇÕES DE MISSÃO CRÍTICA

Abstract

The connectivity allowed by mobile networks has completely changed people's lives over time, to continue this revolution, the fifth generation (5G) network is beginning to be deployed, to meet the new communication requirements of current technologies, especially in the area of IoT in mission critical applications where any delay or failure can be fatal. To meet these requirements, the 5G network needs to be more efficient in ensuring quality of service (QoS), with low latency, with massive support of connected devices and capable of a high data volume rate. The objective of this research is to analyze how 5G mobile technology seeks to implement QoS assurance in mission-critical applications, as well as highlight the benefits and challenges to implement this service. Seeking to verify the possible difficulties of implementing the delivery guarantee model proposed by 5G. This survey was carried out through research in scientific articles, course conclusion works, dissertations, theses and trusted websites related to 5G, mission-critical application communication, URLLC (Ultra-Reliable Low-Latency Communication), QoS and internet of things (IoT). After the survey was concluded, an analysis was carried out to determine how applications are prioritized in terms of availability because they are considered mission critical. Checking the difficulties and benefits found for the implementation of 5G delivery guarantee for technical or legislative mission-critical applications, to get an idea of the challenge that is to obtain the QoS guarantee intended by 5G.
