    5G Interworking Architecture

    In today’s blogpost we will discuss how the interworking architecture of the new 5G system with the existing LTE systems looks like. Inter-working between 4G and 5G will play a very important role in the early deployment of 5G system, which will rely on LTE to be the anchor or underlying system. In the standalone (SA) deployment of 5G, good inter-working with the LTE system to facilitate inter-RAT mobility between the two RATs will be required.

    5G Core Network Functions

    This post touches upon the 5G network functions (NFs) related to core network. Some of them look very similar to the corresponding functions in the previous generations’ core networks. This of course is not surprising, as the network always has to carry out some basic functions such as: communicate with the UE, store its subscription and credentials, allow access to external networks & services, provide security and manage the network access and mobility. However, we will also see some new functions, not present before, which are needed to enable the new network paradigms like slicing and service-based networking.

    3GPP Release-15: Further LTE Enhancements and 5G Normative Work Kick-off

    LTE-Advanced Pro1 was defined within Rel-13, but the standardization didn’t stop there. Further LTE enhancements have been introduced in Rel-14 and recently started Rel-15. In parallel to LTE evolution, both releases initialized, the first set of study and work items towards 5G.  While Rel-14 focused solely on 5G study items, the normative work for the […]
