How it Works
This section describes how this feature works.
-
SGW profile represents SGW service.
-
SGW profile has associated subscriber policy, which helps to select the Operator Policy.
-
Operator Policy has DNN policy associated with it.
-
DNN policy has DNN profile associated with it which has the QCI mark for marking VoLTE subscriber for priority.
Based on the QCI marking as IMS, volteBearer and volteSession flags are set internally when you execute show subscriber
command.
-
volteBearer is a bearer level flag. If bearer QCI is present in marked QCI list, volteBearer flag is set as true and the bearer is considered as volteBearer.
-
volteSession is a session level flag. This flag is set as true if there’s a VoLTE bearer present in any PDN of that subscriber.
