Dear,Brian F. G. Bidulock

	Thank you for your comments!

    For M3UA and SCTP,I'll check if ETSI docs can slove our problems.

    For M2PA, I think national standardization is not enough.
    As I refered in Slides,compared with M3UA and SCTP, Some  procedures in M2PA are  described a little bit simply ,they're referred  to MTP2 directly ,  which  makes IPSTP  providers realizing the  
 procedures in different ways.For  there’s difference between MTP2  
 and M2PA in some aspects. By the protocol test,we find that some IPSTP providers use the same idea as MTP2,and others take the relation between M2PA and SCTP into account.
    Most of the IP Signaling networks exsited are smaller than China Mobile's, only one IPSTP vender is enough .Maybe that's reason why SIGTRAN Working Group hasn't received the Revision Requirement for M2PA.
