Hello,
I’m wondering if I can change the FTUP feature flag or not, so that F-TEID would be allocated by the UP function.
In 3GPP TS 29.244 V15.10.0, it says there’s a function, but dose the latest version of free5GC supports it ?
3GPP TS 29.244 V15.10.0
F-TEID shall be allocated either by the CP function or the UP function. The support of F-TEID allocation by the CP function is mandatory. The support of F-TEID allocation by the UP function is optional. See clause 5.4 of 3GPP TS 23.214 [2].
The UP function shall set the FTUP feature flag in the UP Function Features IE if it supports F-TEID allocation in the UP function (see clause 8.2.25). If so, the CP function shall determine whether F-TEIDs are allocated by the CP function or the UP function based on network configuration. The same F-TEID allocation option shall be used by all the CP functions controlling a particular UP function. The UP function shall reject a request to establish a new PDR with a different F-TEID allocation option than the option used for already created PDRs (by the same or a different CP function), with the cause “Invalid F-TEID allocation option”.
I would appreciate it if you let me know.
Thank you for your help.
