3.3 Symbols

For the purposes of the present document, the following symbols apply:

Gb Interface between an SGSN and a BSC.

Gi Reference point between GPRS and an external packet data network.

Gn Interface between two GSNs within the same PLMN.

Gp Interface between two GSNs in different PLMNs. The Gp interface allows support of GPRS network services across areas served by the co-operating GPRS PLMNs.

Gs Interface between an SGSN and MSC.

R The reference point between a non-ISDN compatible TE and MT. Typically this reference point supports a standard serial interface.

Um The interface between the MS and the GPRS fixed network part. The Um interface is the GPRS network interface for providing packet data services over the radio to the MS. The MT part of the MS is used to access the GPRS services through this interface.
