3.1 Definitions
For the purposes of the present document, the following terms and definitions given in 3GPP TS 22.060 and 3GPP TS 23.060 and the following apply:
2G- / 3G-: prefixes 2G‑ and 3G‑ refers to functionality that supports only A/Gb mode or Iu mode, respectively, e.g., 2G‑SGSN refers only to the A/Gb mode functionality of an SGSN. When the prefix is omitted, reference is made independently from the A/Gb mode or Iu mode functionality.
A/Gb mode: indicates that the text applies only to a system or sub-system which operate in A/Gb mode of operation, i.e. with a functional division that is in accordance with the use of an A or a Gb interface between the radio access network and the core network
Iu mode: indicates that the text applies only to a system or a sub-system which operates in Iu mode of operation, i.e. with a functional division that is in accordance with the use of an Iu-CS or Iu-PS interface between the radio access network and the core network

3.3 Symbols
For the purposes of the present document, the following symbols apply:
Gb Interface between a SGSN and a BSC.
Gi Reference point between the Packet Domain 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 Packet Domain network services across areas served by the co-operating PLMNs.
Gs Interface between an SGSN and MSC.
Iu Interface between the RNS and the core network. It is also considered as a reference point.
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 fixed network part in A/Gb mode. The Um interface is the in A/Gb mode network interface for providing packet data services over the radio to the MS. The MT part of the MS is used to access the GSM services through this interface.
Uu Interface between the mobile station (MS) and the fixed network part in Iu mode. The Uu interface is the Iu mode network interface for providing packet data services over the radio to the MS. The MT part of the MS is used to access the UMTS services through this interface.
