name: CN
full_form: Core Network
context: of Localised Service Area Cells may be grouped into specific localised service areas. Localised Service Area Identity (LSA ID): identifies a localised service area; no restrictions are placed on what cells may be grouped into a given localised service area. The LSA ID can either be a PLMN significant number or a universal identity. This shall be known both in the networks and in the SIM. Identification of PLMN, RNC, Service Area, CN domain and Shared Network Area Public Land Mobile Network Identifier (PLMN-Id): uniquely identifies a PLMN, consists of Mobile Country Code (MCC) and Mobile Network Code (MNC). CN Domain Identifier: identifies a CN Domain Edge Node within the UTRAN for relocation purposes. The CN Domain identifier for Circuit Switching (CS): consists of the PLMN-Id and the LAC The CN Domain identifier for Packet Switching (PS): consists of the PLMN-Id, the LAC, and the RAC of the first accessed cell in the target RNS. CN Identifier (CN-Id): identifies a CN node uniquely
description: The Core Network (CN) manages and controls telecommunications infrastructure operations. It handles user authentication, session management, and connection establishment. The CN encompasses domains like Circuit Switching (CS) and Packet Switching (PS), each with a unique identifier.
explanation: The text refers to the 'Core Network' as a central component responsible for network functions such as authentication and connection management.  It also mentions distinct domains within the Core Network, indicating its role as a broader network entity.
