* @{
*
* The Generic Subscriber Update Protocol (GSUP) is an Osmocom-specific
* non-standard protocol replacing MAP as the protocol between
* MSC/VLR/SGSN and HLR in a 3GPP cellular communications network.
*
* It was designed around the same transactions and architecture as the
* MAP messages/operations, but without the complexity of TCAP and MAP,
* and without the need for ASN.1 encoding.
*
* The purpose is to keep protocol complexity out of OsmoSGSN and
* OsmoMSC, while providing a clean path to an external GSUP to MAP
* translator.
