How to create CRs using this form:
Comprehensive information and tips about how to create CRs can be found at:
http://www.3gpp.org/3G_Specs/CRs.htm. Below is a brief summary:
1) Fill out the above form. The symbols above marked  contain pop-up help information about the field that they
are closest to.
2) Obtain the latest version for the release of the specification to which the change is proposed. Use the MS Word
"revision marks" feature (also known as "track changes") when making the changes. All 3GPP specifications can
be downloaded from the 3GPP server under ftp://www.3gpp.org/specs/ For the latest version, look for the
directory name with the latest date e.g. 2000-09 contains the specifications resulting from the September 2000
TSG meetings.
3) With "track changes" disabled, paste the entire CR form (use CTRL-A to select it) into the specification just in
front of the clause containing the first piece of changed text. Delete those parts of the specification which are not
relevant to the change request.
