Two kinds of EPs are used: - Class 1: Elementary Procedures with response (success or failure), - Class 2: Elementary Procedures without response. 3.2 Abbreviations For the purposes of the present document, the abbreviations given in TR

48、 of LCS-AP messages. 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 local SCTP endpoints may be supported. Mu

49、ltiple remote SCTP endpoints shall be supported. 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. When an entity detects that an SCTP associat
