You can ask the decoding program to send messages to the GSMTAP port, you can
use tcpdump to record a trace and then look at it with wireshark (1.5.x from
svn). The people of the Beijing-Institute-of-Technology were so kind to donate
their dissector.

This link[1] points to the ASN1 file for the messages, it also provides the
D-NWRK-BRDCAST sequence (if you refer for that one).
