name: Gn
full_form: GPRS Network
context: The interoperation procedures describe information flows for Gn/Gp SGSNs and other EPS network elements. All messages between Gn/Gp SGSN and MME, between Gn/Gp SGSN and HSS and between Gn/Gp SGSN and P-GW as well as the therein contained information elements are the same as specified for the adequate TS 23.060[ General Packet Radio Service (GPRS); Service description; Stage 2 ]  [7] procedures that are between Gn/Gp SGSNs. These messages and procedure step descriptions are taken from TS 23.060[ General Packet Radio Service (GPRS); Service description; Stage 2 ]  [7] for explanatory purposes only. These descriptions are in italic text and shall not be modified by the interoperation procedures. It cannot be assumed that the messages and procedure step descriptions that are taken from TS 23.060[ General Packet Radio Service (GPRS); Service description; Stage 2 ]  [7] will be updated when modifications or corrections are performed for TS 23.060[ General Packet Radio Service (GPRS); Service description; Stage 2 ]  [7]. If there are any discrepancies for these messages and procedure step descriptions TS 23.060[ General Packet Radio Service (GPRS); Service description; Stage 2 ]  [7] takes precedence. The messages between the MME and any other node than the Gn/Gp SGSN as well as the therein contained information elements are the same as specified in the main body of this technical specification for the inter RAT Routing Area Update procedure. If there are any discrepancies for these messages the descriptions from the main body of this Technical Specification take precedence. An operator that has pre-Rel-8 SGSNs in its network should use separate EPS bearers for IPv4 and IPv6 addressing, such that both addresses can be maintained when moving to a pre-Rel-8 SGSN from a Rel-8 SGSN or MME (see clause 5.3.1). This is configured into the SGSN and MME nodes which set the Dual Address Bearer Flag depending on whether a UE may or may not be handed over to a pre-Rel-8 SGSN, as specified in clauses 5.3.2.1 and 5.10.2. An operator supporting emergency services shall not have pre-Rel-9 SGSNs in its network where a UE may be handed over.
description: The GPRS Network (Gn) refers to the collective set of interconnected network functions that work together to deliver specific telecommunications capabilities within the General Packet Radio Service (GPRS) architecture. This includes components such as Serving GPRS Support Nodes (SGSNs), Gateway GPRS Support Nodes (GGSNs), and Mobile Management Entities (MMEs), which play critical roles in managing packet data transmission, mobility, and session management for user equipment (UE). The Gn interface is crucial for interoperation procedures between these network elements, ensuring seamless communication and information exchange.
explanation: The abbreviation 'Gn' is classified as a NetworkFunction_Group because it represents the GPRS Network, which encompasses various interconnected network functions working together to provide specific telecommunications capabilities. This aligns with the context provided, highlighting the importance of interoperation procedures between different network elements within the Gn/Gp SGSNs and other EPS network elements.
