The present document specifies the standards for signalling transport to be used across M2 and M3 interfaces. M2 interface is a logical interface between the eNB and the MCE. M3 interface is a logical interface between the MCE and the MME. The present document describes how the M2-AP signalling messages are transported over M2, and how the M3-AP signalling messages are transported over M3.
