Question: In a SIP session with forked responses, how does the PCRF handle QoS authorization for media components when receiving multiple provisional responses with varying QoS requirements?
Option 1: The PCRF authorizes the sum of the bandwidths required by all dialogues to ensure sufficient network resources.
Option 2: The PCRF authorizes the highest QoS requested for each media component by any of the forked responses, without accumulating bandwidth requirements.
Option 3: The PCRF denies additional QoS requests for media components already authorized in previous provisional responses to prevent over-allocation.
Option 4: The PCRF temporarily suspends QoS authorization decisions until the first final answer is received to assess all dialogues collectively.
Explanation: In scenarios with forked responses, the PCRF must efficiently manage network resources while accommodating varying QoS needs. Authorizing the highest QoS requested for each media component ensures that all dialogues can proceed without unnecessary resource accumulation or denial of service, aligning with the principle of optimizing resource utilization in telecom networks.
