MME sends SI-U address in initial context setup request to enodeB, then EnodeB check path by sending echo request to SGW and once response received then it sends ICS response to MME.

LTE: What eNodeB does after receiving S1 setup response ?

In S1-Setup Request message, eNodeB tells max # (6) of broad casted PLMNs. In S1-Setup response message, MME responds back to eNodeB with maxnoofPLMNsPerMME(32) IE. I am not able to find the reason that why maxnoofPLMNsPerMME is 32 even eNodeB can broadcast maxium of 6 ?
