The default is “Availability of the address type is not known”.
3.5.6.2.13 Connection Capability
The Connection Capability section provides information on the status of commonly used communication
protocols and ports in the hotspot.
The Hotspot Operator should configure the AP with information regarding each of the commonly used
protocol and port number values as either closed, open or unknown. Reasonable efforts should be made
to avoid using the value “unknown”.
The mobile device uses connection capability information to make network selection decisions by
determining which services are blocked or supported at the hotspot.
Each entry defines the status for a certain combination of IP protocol and destination port number. The
Connection Capability parameters are:
„
Protocol : The IP protocol. The options available in the drop-down list are:
»
ICMP (Internet Control Message Protocol)
»
TCP (Transmission Control Protocol)
»
UDP (User Datagram Protocol)
»
ESP (Encapsulating Security Payload)
„
Port : The destination port number.
„
Port Status : The options available in the drop-down list are:
»
Closed: The IP protocol or the associated port number is not open for communication (i.e., it is
blocked by a firewall or a Network Address Translation function) in the access network.
»
Open: The IP protocol or the associated port number is open for communication (i.e., it is not
blocked by a firewall or NAT function) in the access network.
»
Unknown: The exact status is not known. The IP protocol or the associated port number may or
may not be open for communication in the access network.
