August 14, 2009 | LTE standards are in matured state now with release 8 frozen. While LTE Advanced is still under works. Often the LTE standard is seen as 4G standard which is not true. 3.9G is more acceptable for LTE. So why it is not 4G? Answer is quite simple - LTE does not fulfill all requirements of ITU 4G definition.

Session and Service Continuity Evolution in 5G Networks

Posted on 28. Feb, 2018 by agaur in Blog, 5G, SSC, 4G, LTE

The explosive growth of data-driven service has been the main driver for 3GPP evolutions in recent years. 5G is expected to provide considerably more flexibility for customization compared to earlier generations. New deployments are expected to serve huge amounts of mobile data traffic, thus requiring very efficient user plane path management.

5G NG-RAN and UE identifiers

Posted on 01. Mar, 2019 by Pankaj in 5G, NG-RAN identifiers

- RAN UE NGAP ID: A RAN UE NGAP ID shall be allocated so as to uniquely identify the UE over the NG interface within an gNB. When an AMF receives an RAN UE NGAP ID it shall store it for the duration of the UE-associated logical NG-connection for this UE. Once known to an AMF this is included in all UE associated NGAP signalling.

5G NG Interface Protocol Architecture

Posted on 01. Mar, 2019 by Pankaj in 5G, NG Interface, NG-C, NG-U

The NG user plane interface (NG-U) is defined between the NG-RAN node and the UPF. The transport network layer is built on IP transport and GTP-U is used on top of UDP/IP to carry the user plane PDUs between the NG-RAN node and the UPF.

NG-U provides non-guaranteed delivery of user plane PDUs between the NG-RAN node and the UPF.
