Namf_MT

Namf_MT service allows a NF to request information related to capabilities to send MT signaling or data to a target UE. The following are the key functionalities of this NF service.

  • Paging UE if UE is in IDLE state and respond other NF after the UE enters CM-CONNECTED state.

  • Response to the requester NF if UE is in CONNECTED state.

  • Providing the terminating domain selection information for IMS voice to the consumer NF
