What is dedicated bearer and what will be the QCI value that i need to set if let say i want to use video service in the enterprise networks?

Dedicated bearers are set up for an eUE if the default bearer cannot meet the QoS requirements of a new video service. Dedicated bearers consist of non-GBR bearers and GBR bearers (for PS services and PTT services). When the eUE requests a new video service, the default bearer cannot provide the required QoS. In this case, a dedicated bearer needs to be set up to provide services. The setup of a dedicated bearer on the enterprise network is initiated by the eAPP.
A default bearer is a non-GBR bearer. A dedicated bearer can be a GBR or non-GBR bearer. A dedicated bearer can generally meet more stringent QoS requirements than the default bearer. Voice services on enterprise networks use the dedicated bearer with the QCI of 1. Video services on enterprise networks use the dedicated bearer with the QCI of 4.
