NAS signalling connection in Mobile Networks
NAS (Non-Access Stratum) protocol is responsible for communication between the UE and the mobile core network in the control plane.
In turn, NAS signalling connection refers to the logical communication channel established between the user equipment (UE) and the mobile core network to exchange signalling messages.
The access network (e.g. eNB in 4G and gNB in 5G), transparently transfers NAS messages exchanged between the UE and the mobile core network.
NAS signalling connection operates in the control plane. And it is separate from the user plane connection, which is responsible for the actual data transmission between the UE and the mobile network.

What is 5G CUPS in 5G Network ?
In this post we will learn what is 5G CUPS. CUPS refers to "control plane and user plane separation". 5G CUPS means that the 5G network is separated into "control plane" and "user plane". In order to understand CUPS, first we should know that in order for the UE to be able to exchange user…

What is an ‘EPS Bearer’ in LTE ?
During 'LTE attach' procedure, the network establishes this EPS Bearer between the UE and the PGW. The PGW assigns an IP address for this Bearer. The UE uses this IP address, in order to communicate with the PDN. In addition, the PGW assigns a QoS for this Bearer, which guarantees the QoS for the data…
