DNAI (Data Network Access Identifier) in 5G Network

DNAI ((Data Network Access Identifier) identifies specific data network access point that a UE (User Equipment) connects to.

It enables the efficient routing and delivery of data to the appropriate data access network. This supports advanced services like multi-access edge computing (MEC).

DNAI information enables the 5G network to steer traffic to the appropriate MEC server, based on the data access network that the UE connects to. The Session Management Function (SMF) dynamically route user traffic to the most suitable data network access point using this information.

DNAI is typically represented as a string, similar to a Uniform Resource Identifier (URI) or a Fully Qualified Domain Name (FQDN).

Here's an example of a possible DNAI format, "mec.edge8.city3.region1.5g.example.com".

    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…

    5G Core Network Architecture

    In this post, we will learn 5G Network Architecture. The control plane in 5G network includes the AMF, the SMF, the AUSF, the UDM, and the PCF. While the user plane includes the UPF. The control plane is not including those network functions only, there are another network functions in the control plane, that will be discussed later.                     In…

    LTE (4G) Network Nodes LTE refers to 'Long Term Evolution', and the architecture of the LTE (4G) network is as following, eNodeB The eNodeB is the 4G site that the UE connects to. It provides the radio interface to the UE. MME MME refers to 'Mobility Management Entity'. The MME is responsible for authenticating the…
