5.6 PFCP Session Handling

5.6.1 General

The following clauses provide details on PFCP Sessions handling.

5.6.2 Session Endpoint Identifier Handling

The SEID uniquely identifies a PFCP session at an IP address of a PFCP entity. The F-SEID is the Fully Qualified SEID and it contains the SEID and IP address. The PFCP endpoint locally assigns the SEID value the peer PFCP side has to use when transmitting message. The SEID values are exchanged between PFCP endpoints using PFCP messages. The PFCP entity communicates to the peer PFCP entity the SEID value at which it expects to receive all subsequent control plane messages related to that PFCP session via the "F-SEID" IE.

The PFCP session related messages shall share the same F-SEID for the PFCP session. An F-SEID shall be released after the PFCP session is released.
