In this section:
In Inter-IMS Network to Network Interface (II-NNI) scenario, the SBC includes session timer specific headers (Session-Expires and Min-SE) in the preconditions UPDATE request sent towards the egress side. In such scenarios, the SBC acting as IBCF node manipulates Session-Expires and Min-SE headers in the in-dialog preconditions UPDATE, sent towards the egress side.
The following call flow depicts the session timer procedure support in early-dialog update request.
