Over the past few years, the number of mobile network users and the range of offered to them services has increased dramatically. This has led to a significant increase in generated in mobile network traffic volume, the transmission of which requires not only high network bandwidth but also the ability of operators to provide users services with the required quality of service (QoS) level. In such conditions, there is the problem of frequency spectrum lack, which requires operators and standardization organizations to search for an effective solution. There are two types of these problem solutions: attracting additional resources, for example, using higher frequencies, such as mmWave, or more efficient use of existing ones, for example, through the use of Licensed Shared Access (LSA) or Licensed Assisted Access (LAA) frameworks. We focus on LAA framework that was introduced by the 3GPP consortium as part of LTE Advanced (LTE-A) technology and defined as a system capable of ensuring the coexistence of LTE and Wi-Fi networks in unlicensed bands. In this paper, we propose two radio admission control schemes to the shared spectrum of 3GPP wireless networks within LAA framework. Services provided to users generate elastic traffic with minimum requirements to QoS level (GB services). © 2019 IEEE.
