The BSSGP layer ensures the transmission of upper-layer data (LLC PDUs) from the BSS to the
SGSN or from the SGSN to the BSS. It ensures the transmission of GPRS Mobility Management
(GMM) signalling and NM (Network Management) signalling. The peer-to-peer communication
across the Gb interface between the two remote BSSGP entities in the BSS and the SGSN is
performed over virtual connections.
