Revision Details

Release

With this release, the P-GW accepts the Modify Bearer Request message that is without Bearer Context, and with old FTEID.

21.14

First introduced.

Pre 21.2

Feature Changes

The change in behavior is to comply with 3GPP TS 29.274 (C4-121937 CR-1254) that is related to Sender FTEID IE in the Modify Bearer Request (MBR) message. P-GW rejects the MBR request with a “Conditional IE Missing” message. With this release, the mandatory check is removed for Bearer Context at P-GW ingress along with Sender FTEID. Also, the P-GW deduces the old and new value of the Sender FTEID during validation.

Previous Behavior: P-GW rejected the MBR message that was without Bearer Context, and with old FTEID.

New Behavior: P-GW accepts the MBR message that is without Bearer Context, and with old FTEID.

Customer Impact: P-GW validates the FTEID and determines to either accept or reject the MBR message.
