Question: In a Relocation Resource Allocation procedure involving GERAN Iu-mode, what is the primary purpose of including the GERAN BSC Container IE in the RELOCATION REQUEST message for RABs being relocated from the CS domain?
Option 1: To provide GERAN-specific information to the target BSC, facilitating successful relocation.
Option 2: To initiate a parallel relocation process in the PS domain for seamless data transfer.
Option 3: To request additional resources from the UTRAN before completing the relocation.
Option 4: To notify the source BSC of an impending failure in the relocation process.
Explanation: The GERAN BSC Container IE is included in the RELOCATION REQUEST message to provide necessary GERAN-specific details to the target BSC, ensuring a smooth relocation process for RABs moving from the Circuit Switched (CS) domain.
