Question: What is the primary distinction between Non UE-associated services and UE-associated services in the context of S1 Application Protocol (S1AP) in E-UTRAN?
Option 1: The type of signaling connection used (e.g., TCP vs. SCTP)
Option 2: The geographical scope within the EPC (e.g., regional vs. global)
Option 3: Whether the service is related to a specific User Equipment (UE) or the entire S1 interface instance
Option 4: The security protocols employed for each service type
Explanation: The correct answer highlights the key difference between Non UE-associated and UE-associated services: the former pertains to the overall S1 interface without a specific User Equipment context, while the latter is specifically related to and maintained for individual UEs. This distinction is crucial for managing signaling connections efficiently in E-UTRAN.
