Keywords:
GSM, mobile communication, authentication, HLR, VLR, EIR, IMEI, encryption, network management, OMS, NMC, mobile station, identification, protocols, security, network centers, EIR, BSS, IWF.Abstract
This article explains in detail the main components of the GSM mobile communication network, their principles of interaction, authentication processes and the functions of various centers (HLR, VLR, EIR, OMS, NMC). The article presents the composition of long-term and temporary data stored in the HLR (Home Location Register) and VLR (Visitor Location Register) systems. It also covers how subscriber information is stored in the network, how it is updated depending on the location of mobile stations, and the authentication and encryption processes. The article also provides complete information on the important roles that network management systems, including OMS and NMC, play in ensuring their effective operation. The principles of interaction of these elements and their impact on other elements in the system are explained.
