name: AHR
full_form: Access point Home Register
context: consists of two steps: 1, The registration of H(e)NB location information ; 2, The authentication of H(e)NB location. Step1 is a Location Registration step, and only occurs when H(e)NB powers on for the first time and connects to core network through IP backhaul. Step 1 consists of the following sub-steps: : , H(e)NB sends a request message to AHR, carrying its IP address in this message. 1b, AHR sends a location information query message to the CLF, carrying the received IP address. , Based on the IP address, the CLF queries its database to obtain the access line location identifier of the H(e)NB, which is used to identify the access line location of the H(e)NB ,such as the port numbers bound with the IP addresses, 1d, AHR determines the location of the H(e)NB based on the obtained identifier. AHR registers the location of this H(e)NB. 1e, AHR replies response message to H(e)NB. After step1, AHR can store access line location identifier as an attribute of H(e)NB profile, treating it
description: The Access point Home Register (AHR) is a network function responsible for managing the registration and authentication of Home eNodeB (H(e)NB) locations within the core network. It interacts with other network functions, such as the CLF, to obtain location information and store it as an attribute of the H(e)NB profile.
explanation: AHR is classified as a Network Function based on its role in managing H(e)NB location registration and authentication, as described in the context. It performs specific tasks, such as sending query messages, determining locations, and storing attributes, which are characteristic of network functions within the telecommunications infrastructure.
