09.613GPPGeneral Packet Radio Service (GPRS)Interworking between the Public Land Mobile Network (PLMN) supporting GPRS and Packet Data Networks (PDN)TS

4.1 Key characteristics of PLMN

The GSM PLMN is fully defined in the GSM technical specifications. The GPRS related key characteristics are found in 3GPP TS 02.60 [2] and 3GPP TS 03.60 [3].

4.2 Key characteristics of PSDN

Packet Switched Data Networks (PSDNs) are defined in the relevant ITU-T Recommendation X series.

4.3 Key characteristics of IP Networks

The Internet is a conglomeration of networks utilising a common set of protocols. IP protocols are defined in the relevant IETF STD specifications and RFCs. The networks topologies may be based on LANs (e.g. ethernet), Point‑to‑Point leased lines, PSTN, ISDN, X.25 or WANs using switched technology (e.g. SMDS, ATM).
