name: HMS
full_form: Home NodeB Management System
context: When the HNB is initially powered up, it shall contact with HMS (initial) to discover HNB-GW for the first step. HMS (initial) assigns the HNB corresponding local access information of Security Gateway (serving), HMS (serving) and optionally HNB-GW according to the HNBâs location information. The HNB-GW information shall be provided either by the HMS (initial) or the HMS (serving). The HNB is pre-configured with the address information of HMS (initial) and Security Gateway (initial) and with an operator trusted root CA certificate allowing the validation of the certificate presented by HMS (as TLS server) or Security Gateway (as IKEv2 responder), while HMS (serving) may be physically different from HMS (initial). The address information of Security Gateway (initial) should be consistent with that in the certificate presented by Security Gateway (initial). When authentication between HNB and HMS (initial) is needed, the address information of HMS (initial) should be consistent with that
description: The Home NodeB Management System (HMS) is a network function responsible for managing Home NodeBs (HNBs), including their discovery, configuration, and security. It plays a crucial role in the initial setup and operation of HNBs within the network.
explanation: HMS is classified as a Network Function based on its role in managing HNBs, as described in the context from 3GPP TS 32.583. The HMS is involved in discovery procedures, assigns local access information, and handles authentication between HNBs and itself or other network elements.
