The term ANDSF was first conceived by the 3GPP in Release 8 as part of the effort to standardise the behavior of the ever-growing abundance of 3GPP-compliant UEs (e.g. smartphones) that can also access non-3GPP data networks.
Non-access stratum (NAS) is a functional layer in the NR, LTE, UMTS and GSM wireless telecom protocol stacks between the core network and user equipment. [1] This layer is used to manage the establishment of communication sessions and for maintaining continuous communications with the user equipment as it moves.
System Architecture Evolution (SAE) is the core network architecture of mobile communications protocol group 3GPP's LTE wireless communication standard.. SAE is the evolution of the GPRS Core Network, but with a simplified architecture; an all-IP Network (AIPN); support for higher throughput and lower latency radio access networks (RANs); and support for, and mobility between, multiple ...
Access network discovery and selection function (ANDSF) is the most complete 3GPP approach to date [25] for controlling offloading between 3GPP and non-3GPP access networks (such as Wi-Fi). The purpose of the ANDSF is to assist user devices to discover access networks in their vicinity and to provide rules (policies) to prioritize and manage ...
The access stratum (AS) in computer networking and telecommunications is a functional layer in the UMTS and LTE wireless telecom protocol stacks between radio network and user equipment. [1] While the definition of the access stratum is very different between UMTS and LTE , in both cases the access stratum is responsible for transporting data ...
An evolved IP Multimedia Subsystem (IMS) developed in an access independent manner 3GPP is a consortium with seven national or regional telecommunication standards organizations as primary members ("organizational partners") and a variety of other organizations as associate members ("market representation partners").

The second variant of LTE-Unlicensed is Licensed Assisted Access (LAA) and has been standardized by the 3GPP in Rel-13. LAA adheres to the requirements of the LBT protocol, which is mandated in Europe and Japan. It promises to provide a unified global framework that complies with the regulatory requirements in the different regions of the world.
