Spec Reference:


GSUP used to be called "GPRS Subscriber Update Protocol" and its use was limited to the SGSN.
However, GSUP has since made it to libosmocore and was recoined as "Generic Subscriber Update Protocol".
It will be used by OsmoNITB / OsmoMSC.

In the osmo-gsm-manuals, edit the GSUP information to reflect these changes:
  • rename to 'Generic ...'
  • as client, don't assume it is always the SGSN

When the VLR #1592 is implemented: Possibly put these chapters elsewhere and/or also include in the OsmoNITB OsmoMSC manual.
