5G: Is it necessary to support LTE interfaces at next generation core network (NGCN) ?

0 votes

I was going through deployment options 4A and 7, in which LTE eNodeB interacts with NGCN for control plane and user plane.
I am thinking the scenarios that when an operator would require particular option 7 in which eNodeB control and user plane both ends interface towards NGCN ? If this is the case then S1-AP and NG-AP both protocols will have to implement at next generation core network.
Is my understanding of option 7 is correct ?

Hi,

Yes your understanding is right, if operator wants to implement option 7 then eLTE should evolve s1-AP to NG-AP. This scenario will reduce deployment cost for stadalone NG, where you require either EPC or NG_C

Technically, option 7 requires eNB to be upgraded to ng-eNB and therefore would not require S1-AP anymore. However, upgrading all eNBs to ng-eNBs will not be feasible for many operators, so vendors are offering 5GC with built in EPC+ functionalities.

In LTE network, UE registers with network using attach procedure. MME supports couple of states such as EMM-REGISTERED, EMM-DEREGISTERED to maintain the status of UE registration. I want to know that how network registration is being implemented at 5G core ? Is it as same as LTE network EMM states ?

Network slicing is a concept by using that virtual networks are created for different sets of devices. In case of next generation radio (NR), is there any change at L1/L2 to support network slicing compare to the LTE implementation ?
