可以看TS25.412还有TS29.202。但这些都没有详细说明。现在很多厂家做SIGTRAN可能都采用了IETF的标准，就连TS25.412里面也提到了这点：

M3UA refers to the SCCP adaptation layer "SS7 MTP3 – User Adaptation Layer " (IETF RFC 3332 [17]) also developed by the Sigtran working group of the IETF. An RNC equipped with the M3UA stack option shall have client functionality. This enables the RNC to report to the MSC when it is a newly introduced entity in the network.

3.
SCTP refers to the Stream Control Transmission Protocol (IETF RFC 2960 [16]) developed by the Sigtran working group of the IETF for the purpose of transporting various signalling protocols over IP networks. The checksum method specified in IETF RFC 3309 [30] shall be used instead of the method specified in IETF RFC 2960 [16]. Multi-homing is a way to achieve redundancy with SCTP between two endpoints, of which one or both is assigned with multiple IP addresses. SCTP endpoints shall support a multi-homed remote SCTP endpoint.
