PDU Session Unstructured
Unstructured PDU Session Type
PDU session transporting arbitrary raw binary data without protocol headers, optimized for lightweight IoT.
Technical Explanation
Unstructured PDU Sessions transport opaque binary byte streams without IP or Ethernet headers. Designed for constrained sensor devices (mMTC), data can be routed via point-to-point N6 tunnels or delivered directly to application servers via the Network Exposure Function (NEF).
Key Functions
- Transports opaque binary payloads with zero protocol header overhead
- Optimized for ultra-low power sensor telemetry in smart utility metering
- Supports delivery via Point-to-Point N6 tunnels or NEF API gateways
