5G N26 Interface – 5G to 4G Interworking

Hello Experts.

N26 interface is an interface which interconnects the 5G Core network function AMF with 4G network node MME and enables interworking between 5G to 4G and visa versa.

Key Pointers

  1. N26 is the interface between 5G AMF and 4G MME
  2. N26 interface is based on GTPv2 instead of Httpv2 which is known for 5G Service Based Architecture
  3. It enables interworking between 5G and 4G to support Inter-RAT mobility
  4. N26 interface support seamless session continuity for Voice and Data during inter-RAT handover (5G to 4G and 4G to 5G)
