Question: What is a requirement for a UE that supports RAN-assisted WLAN interworking based on ANDSF policies?
Option 1: The UE must support transmission of RAN assistance parameters via dedicated signaling but not necessarily via system information.
Option 2: The UE shall support reception of RAN assistance parameters relevant for those policies, via both system information and dedicated signaling.
Option 3: The UE is only required to receive RAN assistance parameters through system information, with dedicated signaling being optional.
Option 4: Support for receiving RAN assistance parameters is not mandated for UEs enabling RAN-assisted WLAN interworking based on ANDSF policies.
Explanation: For a UE to effectively utilize RAN-assisted WLAN interworking based on ANDSF policies, it must be capable of receiving the necessary RAN assistance parameters through all specified communication means. This ensures seamless integration and optimal performance. Thus, supporting reception via both system information and dedicated signaling is imperative, aligning with the principles of efficient network-resource utilization and enhanced user experience in telecom networks.
