Question: In IMS, when a UE is engaged in multiple sessions, what is the primary purpose of the P-CSCF providing a priority sharing indicator to the PCRF/PCF for media flows of the same media type?
Option 1: To ensure each media flow always gets dedicated network resources regardless of other ongoing sessions.
Option 2: To enable the use of a single bearer per QCI/5QI for multiple sessions with the same media type, sharing the same priority.
Option 3: To mandate pre-emption of lower-priority media flows in favor of higher-priority ones across all UEs on the network.
Option 4: To notify the PCRF/PCF that the UE is capable of handling multiple concurrent sessions without resource allocation adjustments.
Explanation: The correct answer highlights the key benefit of priority sharing in IMS and media flow management. By allowing multiple sessions of the same media type to share the same priority on a single bearer (per QCI/5QI), network resources are utilized more efficiently, avoiding separate bearers for each session based on different service priorities.
