Description

   Information processing method and device   

The invention belongs to the field of communication technology, and in particular, relates to an information processing method and device.

And session management capabilities. The only control interface interface between the UE (User Equipment, user equipment) and the 5G core network is the N1 interface. All control plane messages sent by the UE to the 5G core network are transmitted through the N1 interface, including N1 MM (Mobility Management, Mobility Management) messages and N1 SM (Session Management, Session management) messages.

Features of the N1 interface include:

One N1 NAS (Non-access stratum, non-access stratum) connection is used for registration management, signaling connection management, SM related messages and process processing. The only N1 endpoint on the network side is AMF. For example, AMF forwards SM-related information to SMF. AMF is responsible for the registration management and signaling connection management part in NAS signaling. SMF is responsible for the session management part in NAS signaling.

RM (Registration Management) / CM (Connection Management) NAS messages and SM NAS messages and the corresponding processes are decoupled. Therefore, AMF needs to support NAS routing capabilities. The AMF can decide whether to accept the RM / CM part in the NAS request, but it is unknown to the SM part in the NAS signaling. When an SMF is selected to serve a certain PDU (Protocol Data Unit, protocol data unit) session, the AMF needs to be able to ensure that all NAS signaling related to the PDU session is handled by the same SMF instance. The SMF notifies the AMF that a PDU session is released.
