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.

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 ?
