Question: In the context of Policy and Charging Control (PCC), what is a prerequisite for the PCEF and PCRF to support a specific procedure related to handling of late arriving requests?
Option 1: The IP-CAN session must be in an active state.
Option 2: Support for a detection and handling procedure is already enabled between PCEF and PCRF.
Option 3: Both PCEF and PCRF must have previously established a minimum of three IP-CAN sessions.
Option 4: The PCC system must be operating in a 5G network environment.
Explanation: According to the specifications, for a specific handling scenario procedure to be used and supported, it requires support for another related detection and handling procedure, indicating a dependency where one procedure's support is contingent upon the other's, highlighting coordinated functionality importance within PCC systems.
