Question: Which of the following IGMP versions is NOT supported by Packet Filter Set for IPTV service in a PDU Session, as per Wireless and wireline convergence access support for the 5G System specifications?
Option 1: IGMPv2 (specified in RFC 2236)
Option 2: IGMPv1 (defined in RFC 1112)
Option 3: IGMPv3 (specified in RFC 4604)
Option 4: Both IGMPv2 and IGMPv3
Explanation: According to the specifications, for PDU Sessions used for IPTV services, Packet Filter Sets support IGMPv2 (RFC 2236) and IGMPv3 (RFC 4604), but explicitly state that packets filters for **IGMPv1 (defined in RFC 1112)** are not supported. This highlights the importance of version-specific protocol support in telecom networks to ensure compatibility and efficient service delivery, such as IPTV streaming.
