With the commercial launch of 5G technologies and fast pace of expansion ofcellular network infrastructure, it is expected that cellular and mobilenetworks traffic will exponentially increase. In addition, new services areexpected to spread widely, such as the Internet of Things connected to mobilenetworks. This will add additional burden in terms of traffic load. As aresult, some studies suggest that mobile traffic may increase more than 1000times compared to the amount of traffic that is generated nowadays. This meansthat network resources for mobile services must be managed and controlled in asmart way, because resources are always limited, but the demand for servicesand the need for keeping user equipment always connected to mobile networks canbe considered unlimited, leaving gap between huge service demands and availableresources. In order to narrow this gap, major consideration should be given tothe management of network resources to avoid network congestion and performancedegradation during peak hour/s and traffic spikes, and allow access to networkservices to more customers when demand is high. On the other hand, guaranteeingquality of service requirements for the wide range of new services is anotherchallenge that must be met in 5G networks. In this paper we will review 5Gnetworks characteristics and specifications, then carry out a survey onresource management and QoS provisioning to improve and manage resourceutilization in 5G networks.
