Question: In a Self-Organizing Network (SON) with RACH optimization enabled, how should an IRPAgent handle conflicting parameter value requests from multiple SON functions when no policy is defined by the IRPManager?
Option 1: Automatically disable RACH optimization to prevent conflicts.
Option 2: Apply a random selection of parameter values from the conflicting requests.
Option 3: Request manual intervention from the network administrator for each conflict.
Option 4: Apply default policies as defined by the SON coordination function.
Explanation: According to SON coordination requirements, if no policy is given by the IRPManager, the IRPAgent should apply default policies to handle conflicts between SON functions requesting different parameter values. This ensures a structured approach to resolving conflicts without requiring immediate external intervention, thus maintaining network stability and performance.
