X-Header Encryption
X-header encryption enables encryption of X-header fields before insertion. If X-header insertion has already happened for an IP flow (because of any X-header format) and the current charging-action has the first-request-only flag set, the X-header insertion will not happen for that format. If the first-request-only flag is not set in a charging-action, the insertion for that X-header format continues happening in other suitable packets of that IP flow.
Changes to the X-header format configuration do not trigger re-encryption for existing calls. The changed configuration will however, be applicable for new calls. The changed configuration will also apply at the time of the next re-encryption, to the existing calls for which the re-encryption timeout is specified. If encryption is enabled for a parameter while data is flowing, since its encrypted value will not be available, insertion of that parameter stops.
Note | This feature does not support flow recovery. |
