For 3G, it represents the GGSN IPv4 address that is used by the GTP control
plane for the context establishment on the Gn interface.
For 4G, it represents the P-GW IPv4 address that is used on the S2a or S2b
interface for the GTP session establishment.
If not present, the WLAN-GW will send a DNS query based on the APN
name derived from [26-6527-146] Alc-Wlan-APN-Name or local
configuration.
Used to signal charging-characteristic IE content.
International Mobile Equipment Id and its Software Version, this will be
echoed in the GTP-C setup messages.
This attribute specifies the location information for a given UE that will be
echoed in the ULI IE in GTP-C setup messages. The format and radius-to-
GTP mapping is specified in 3GPP specification 29.061. If not present, no
user location will be reflected in GTP. Radius servers can use the information
from e.g. called-station-id, Alc-Wlan-SSID-VLAN and/or NAS-Port-ID to
create a corresponding ULI value.
