Question: In a scenario where an IMS session is forked in the network, resulting in multiple responses for the same session, how does the PCRF/PCF handle resource authorization?
Option 1: The PCRF/PCF authorizes the 'logical AND' of the resources requested in the responses to ensure conservative allocation.
Option 2: The PCRF/PCF may authorize the 'logical OR' of the resources requested in the responses to accommodate all potential paths.
Option 3: The PCRF/PCF denies authorization until the session is unforked and only one response remains for the session.
Option 4: The PCRF/PCF splits the available resources equally among all responses for the forked session.
Explanation: When an IMS session is forked, multiple paths are temporarily established. Authorizing the 'logical OR' of the resources ensures sufficient allocation to support any potential path, preventing resource constraints from causing failures. Once the session establishment indication is received, the PCRF/PCF refines authorization to match the actual path taken, optimizing resource utilization.
