    接口
    Ga Charging data collection interface between a CDR transmitting unit (e.g. an SGSN, SGW, PDN GW or a GGSN) and a CDR receiving functionality (a CGF).
    Gb    Interface between an SGSN and a BSS.
    Gi    Reference point between a GGSN and a packet data network.
    Gn Interface between two SGSNs within the same or different PLMNs or between an SGSN and a GGSN within the same PLMN.
    Gp Interface between a SGSN and a PGW/GGSN in different PLMNs. The Gp interface allows support of GPRS network services across areas served by the co-operating GPRS PLMNs.
    Iu    Interface between the RNS and the core network. It is also considered as a reference point.
