We know, in lte, an eNodeB can connect to multiple MMEs. Can someone please explain in details ?
Apart from load balancing, is there any other reason ?
LTE Ran-Sharing feature, eNodeB connects to multiple MMEs using s1-flex.
I understood the basics of MOCN through which same eNodeB is controlled/used by multiple operators. Is it possible to do on dynamic basis ? if yes then what all things need to be coordinated among operators to make it happen smoothly ?
Which parameters at eNodeB would be taken into consideration to trigger 'n' numbers of S1 connections with same MME or different MMEs ?
Note: My query is related to macro eNodeB.
Need clarity on following items:
1. What is the use of "UE selected plmn" information for an eNodeB ?
2. Is the ECGI/TAI constructed based on the primary plmn (PLMN broadcasted in 0th index in SIB1 ) or based on the UE selected PLMN ?
