Hi Arun, You need to look in the SDP body for the bandwidth allocated in to the respective video codec.. Based on that you can calculate the RR and RS with below logic.
If UE indicates AS parameter 41 mbps, then RS Parameter = 1.25% of AS parameter = 512 kbps RR Parameter = 3.75% of AS Parameter = 1537 kbps Same logic applies in your case too...

After some operation DUT A receives bearer modification from the NW with DL MBR say (400) [In the incoming OTA message] How this DL MBR should be divided among the AS, RR and RS Example 1: AS: 400 RS: 5000 RR: 6000 Example 2: AS: 389 [400 - (5000+6000)] RS: 5000 RR: 6000 I am not clear with this calculation please help to share the inputs *RFC 3550:* Appendix B - Changes from RFC 1889 - The description of the session bandwidth parameter is expanded in Section 6.2, including a clarification that the control traffic bandwidth is in addition to the session bandwidth for the data traffic. -- With Regards Arun A.
