Feature Description
Architecture
Location Service consists of the following layers as part of the non-roaming location services architecture:
-
UE: The UE represents end-user devices, such as smart phones, tablets, or IoT devices. These devices interact with the network.
-
GMLC: GMLC provides the location information services related to mobile devices.
-
LCS Client: The LCS client is an external entity or application that requests location information for a specific mobile device.
-
LRF: The LRF is a component within the Location Services (LCS) architecture in cellular networks. LRF retrieves and provides the location information for mobile devices or user equipment (UE).
-
LMF: The LMF determines the geographical location of the UE.
-
AMF: The AMF is a key component in 5G networks. It manages mobility, session management, and security for user devices.
-
UDM: The UDM handles user-related data, including authentication, authorization, and subscription information.
-
RAN: The RAN connects user devices to the core network. It includes base stations and antennas.
-
N1 Interface: The N1 interface connects the UE and the RAN. It carries user data and control signaling.
-
N2 Interface: The N2 interface connects the AMF and the RAN. It handles signaling and data transfer between the core network and the RAN.
-
NL1 Interface: NL1 interface connects the LMF to the UE.
-
NL2 Interface: NL2 interface connects the AMF to the GMLC.
