M2AP 3GPP TS 36.443 interface implemented:

Browse Source 
1.MCE (Multicast Control Entity) entity developed (new dedicated task developed: TASK_MCE_APP)
	2.eNB side M2 interface procedures (new dedicated task developed: TASK_M2AP_ENB)
	3.MCE side M2 interface procedures (new dedicated task developed: TASK_M2AP_MCE)
	4.ASN1 bindings for m2ap-14.0.0.asn1 implemented and tested
	5.MCE config parameters
