Question: What is the minimum set of parameters that a Packet Filter Set must support for IP PDU Session Type, according to 3GPP specifications?
Option 1: Source/destination IP address or IPv6 prefix and Protocol ID of the protocol above IP/Next header type.
Option 2: Any combination of source/destination IP address or IPv6 prefix, source/destination port number, Protocol ID of the protocol above IP/Next header type, Type of Service (TOS) / Traffic class and Mask, Flow Label, Security parameter index, and Packet Filter direction.
Option 3: Source/destination IP address or IPv6 prefix, source/destination port number, and Protocol ID of the protocol above IP/Next header type.
Option 4: Type of Service (TOS) / Traffic class and Mask, Flow Label, Security parameter index, and Packet Filter direction.
Explanation: According to the 3GPP specifications, a Packet Filter Set for IP PDU Session Type must support Packet Filters based on any combination of at least eight parameters, including source/destination IP address or IPv6 prefix, source/destination port number, Protocol ID of the protocol above IP/Next header type, Type of Service (TOS) / Traffic class and Mask, Flow Label, Security parameter index, and Packet Filter direction.
