Question: What is the primary purpose of the 'Reset Function' on the S1 interface between the eNB (Evolved Node B) and the MME (Mobility Management Entity) in an E-UTRAN (Evolved Universal Terrestrial Radio Access Network)?
Option 1: To notify the peer entity of a logical error occurrence.
Option 2: To initialize the peer entity after node setup or following a failure event.
Option 3: To manage the handover of User Equipment (UE) between different eNBs.
Option 4: To update the radio resource allocation on the S1 interface.
Explanation: The reset function is crucial for restarting or reinitializing the communication between the eNB and MME after specific events, such as node setup completion or the occurrence of a failure. This ensures that both entities can correctly interoperate on the S1 interface, which is vital for managing sessions, handling mobility, and maintaining overall network stability.
