07.603GPPGeneral Packet Radio Service (GPRS)Mobile Station (MS) supporting GPRSTS

3.1 Definitions

Refer to: GSM 02.60 [2].

In GSM 02.02 the bearer services are described. The general network configuration is described in GSM 03.02 and the GSM PLMN access reference configuration is defined in GSM 04.02. The various connection types used in the GSM PLMN are presented in GSM 03.10. Terminology used in the present document is presented in GSM 01.04. For support of data services between GSM PLMN and other networks see GSM 09-series of Specifications.

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.
