1.MME entity developed to handle M3 side (new dedicated task developed: TASK_MME_APP) (these procedures should be moved to OPENAIR-CN ... just implemented to easy the E-UTRAN MBMS stuff development)
2.MCE side M3 interface procedures (new dedicated task developed: TASK_M3AP_MCE)
3.MME side M3 interface procedures (new dedicated task developed: TASK_M2AP_MME) (these procedures should be moved to OPENAIR-CN ... just implemented to easy the E-UTRAN MBMS stuff development)
4.ASN1 bindings for m3ap-14.0.0.asn1 implemented and tested
5.MME config parameters
