Semi-permanent SCTP associations shall be established between MME and E-SMLC, i.e. the SCTP associations shall remain up under normal circumstances. Local multi-homing should be supported. Remote multi-homing shall be supported. Multiple l

When multiple local or remote SCTP endpoints are configured, several simultaneous SCTP associations shall be supported between MME and E-SMLC. The MME shall establish the SCTP association. Since under normal operation there should always be an SCTP association established between an MME and an E-SMLC, if the E-SMLC needs to initiate a message towards an MME it shall do so over an existing SCTP association already established with that MME.
