LTE E2E optimization case

[amadeo]

Hi Guys,
I am looking for a case that involve LTE end to end optimization with all visibility. For example, if we have high ERAB drop due to others, where eventually we found out due to core timer was too small. Or if VoLTE, the IMS sending release order due to SGW/C timer for data inactivity expired (RTP gap). Or vice versa. Please kindly share or discussed here.

Thank you.

cheers,

Let's play on. RAN Volte drop is not quite represent customer experience due to call re-establishment. Actual drop from SIP cause code is more interesting and also the amount of RTP gaps will constitute to customer experience.

SIP Media Inactivity Timer (MIT). In RAN, e******* has timer called timeout to regulate packet gap.
