This clause defines AT commands that a TE may use to control MT supporting UAE layer. The UAE layer supports UAS application communication between the UE and the UAE server and UAS application communication among UEs over LTE-Uu or NR-Uu as defined in TS 24.257
A comprehensive set of UAE layer-specific commands is defined to provide the flexibility needed by the more complex MT. The commands are designed to be expandable to accommodate new UAE layer feature options and interface protocols, merely by defining new values for many of the parameters. The commands use the extended information and error message capabilities described in the present specification.
The +CUAEACT command activate or deactivate the UAE layer support in the MT. Once the UAE layer is enabled, then the MT can request the registration for receiving UAV application messages from the UAS application specific server by performing the UAS UE registration procedure according to TS 24.257, clause 6.4
using the +CUAEREG command.
