5.9 Usage of Vendor-specific IE

29.2443GPPInterface between the Control Plane and the User Plane nodesRelease 17TS

Vendor-specific IEs are defined to cover requirements and features not specified by 3GPP.

NOTE 1: When an IE is intended to be used by more than one vendor, the definition of the IE is encouraged to be specified by 3GPP to ease implementation and interoperability.

NOTE 2: The PFCP entities can use Vendor-specific IE(s) in the PFCP message relevant to the PFCP Association Setup procedure to learn which vendor specific enhancements are supported by the peer.

Vendor-specific IE may be sent with any PFCP message. Vendor-specific IE may be added directly to a PFCP message, or by embedding it into a grouped IE.

In a network with Vendor specific enhancements, unrecognized vendor specific IEs shall be handled as unknown optional IEs.
