for this go through the chapters defining the operations in the earlier chapters of MAP specifications that clearly define what is the purpose of each operation and between which network nodes are they meant for. Or for more detailed call-flows you can refer to ETSI 23.018 specifications.

Still have some doubts. In TCAP/MAP ASN.1 standard documentation there are: - Operation packages like locationUpdatingPackage-v3 OPERATION-PACKAGE ::= { CONSUMER INVOKES { updateLocation} SUPPLIER INVOKES { forwardCheckSs-Indication} } which I don't know what are them for, how to use them and in what module should be defined? thanks, Eduardo Figoli ----- Original Message ----- From: "John Larmouth" <[EMAIL PROTECTED]> To: "Salim Alaoui" <[EMAIL PROTECTED]> Cc: "Eduardo Figoli" <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Friday, December 17, 2004 1:56 PM Subject: Re: [ASN1] APPLICATION-CONTEXT and PACKAGE-OPERATIONS > Probably a better (more practical!) answer than mine! > > John L > > > Salim Alaoui wrote: > > > hello eduardo, > > > > In ETSI specs there is, as you probably know, different versions.
