The 3GPP standard 3GPP is the international body for the development of 5G standardization. In 3GPP, both the core network (5G Core) and the radio access (5G RAN) were defined. The 5G Core is home to all the functional components that allow the network operator/manager to enable advanced features and define the characteristics of…

In the evolution of mobile networks from 3G to 4G and 5G, a key aspect is the separation between control plane and user plane. This separation, called CUPS (Control and User Plane Separation), is supported by the strict definition by 3GPP of a set of Network Functions (NFs) and interfaces within the Core Network (CN)…

ATSSS Starting from 3GPP 5G rel-15 specifications, it was proposed to enable an optional non-3GPP access to the Core Network (CN), alternative to the 3GPP one. 3GPP access refers to the nominal UU New Radio (NR-Uu) interface with the RAN of a 5G network; non-3GPP access instead opens to the possibility of connecting a UE…

A QUIC-based multi-link management including satellite links In the recent years, web has evolved significantly passing from simple HTML content-based services to complex multimedia streaming (both live and on-demand), interactive and cloud applications which are generating dynamic and greedy traffic, leading to the need to improve network performance in terms of higher capacity and lower…
