I worked for VoLTE feature and found that AA-Request and AA-Answer messages are exchanged between AF and PCRF to get established a dedicated bearer at LTE network nodes for an UE. For VoLTE call, dedicated bearer is established with QCI "1" and that is a GBR bearer.
Though I have not worked on any other service other an VoLTE, I believe AF can ask network to establish more dedicated bearers and those bearers can be GBR/non-GBR.

Suppose there is a requirement of giving the same QOS to set of application ( Youtube and Whatsapp ) then will there be only one dedicated bearer for both application or two dedicated bearers will be established?

If one bearer is established for both the application then what if the user stops using one of the applications or the policy is removed from GGSN for one application, will the dedicated bearer be terminated?

While going through 29.274 specification, I observed "Bearer TFT" is optional in Create Session Request/Response messages while it's presence is mandatory in Create Bearer Request message. Reasons are not explained in the specification. Can someone please explain it ?
