In this section, GTP uplink application specific attributes are detailed. These attributes are applicable to WLAN Gateway as well as ESM scenarios such as Hybrid Access.
Attribute ID | Attribute name | Description |
---|---|---|
26.6527.145 |
Alc-MGW-Interface-Type |
This contains the interface type that is used to determine the type of GTP-C connection, overrides local configuration. |
26.6527.146 |
Alc-Wlan-APN-Name |
Specifies the Access Point Name (APN) for which a GTP-C session is set up. This is signaled in the GTP-C setup and may be used to determine the IP address of the GGSN/P-GW by performing a DNS query if the [26.10415.5] 3GPP-GGSN-Address attribute is not present. This overrides a locally configured APN. |
26.6527.147 |
Alc-Mslsdn |
Contains the MSISDN (telephone number) of the UE, and is included in GTP-C signaling. When not present the corresponding GTP-C Information Element is not sent. |
26.6527.179 |
Alc-GTP-Local-Breakout |
Specifies if part of the UE traffic can be locally broken out (such as, NATed and routed), subject to matching an IPv4 filter entry with action gtp-local-breakout, associated with the UE. |
26.6527.205 |
Alc-GTP-Default-Bearer-Id |
When establishing a GTP connection for a UE, this specifies the bearer ID (GTPv2) or NSAPI (GTPv1) that is used for the data path connection. If not provided, a default value of 5 is used. |
26.6527.219 |
Alc-Egress-Report-Rate-Subtract |
This value is subtracted from the base downlink AMBR value calculated using the report-rate mechanism. This attribute is only interpreted if report-rate is enabled in the applicable SLA profile: configure subscriber-mgmt sla-profile sla-profile-name egress report-rate. |
26.10415.1 |
3GPP-IMSI |
This is used to identify the host in a GTP-C connection. If not present and a gtp-c connection is requested, the subscriber-id or username in the EAP-SIM message is parsed as an IMSI. This should be provided for any GTP-C user. |
26.10415.3 |
3GPP-PDP-Type |
Specifies which address type should be requested from the P- GW: ipv4, ipv6 or ipv4v6. If this attribute is not present, the value under configure router | service vprn service-id gtp uplink pdn-type is used. |
26.10415.5 |
3GPP-GPRS-Negotiated-QoS-Profile |
Used to signal the QOS for default bearer or primary PDP context using GTP "QOS IE" in create-PDP-context and "Bearer QOS" in create-session-request. |
26.10415.7 |
3GPP-GGSN-Address |
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 sends a DNS query based on the APN name derived from [26.6527.146] Alc-Wlan-APN-Name or local configuration. |
26.10415.13 |
3GPP-Charging-Characteristics |
Used to signal charging-characteristic IE content. |
26.10415.20 |
3GPP-IMEISV |
International Mobile Equipment ID and its Software Version, this is echoed in the GTP-C setup messages. |
26.10415.21 |
3GPP-RAT-Type |
Specifies the value that is signaled in the RAT Type IE during GTPv1/GTPv2 setup. If this attribute is not present, the value under configure subscriber-mgmt gtp peer-profile profilename rat-type type is used. |
26.10415.22 |
3GPP-User-Location-Info |
This attribute specifies the location information for a specific UE that is 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 is reflected in GTP. RADIUS servers can use the information from for example, attributes [30] Called-Station-Id, [26.6527.206] Alc-Wlan-SSID-VLAN or [87] NAS-Port-Id to create a corresponding ULI value. |
Attribute ID | Attribute name | Type | Limits | SR OS format |
---|---|---|---|---|
26.6527.145 |
Alc-MGW-interface-Type |
integer |
values [1 to 3] |

Alc-Wlan-APN-Name |
string |
100 chars if both <NI> and <OI> parts are present. 63 chars if only the <NI> part is present. |
The APN Name attribute must be formatted as <NI>[.mnc<MNC>.mcc<MCC>.gprs]. The Operator-ID (OI) part is optional and is automatically derived from the IMSI if it is not present. The APN FQDN generated for DNS resolution is composed of the Network-ID (<NI>) portion and the Operator-ID (OI) portion (<MCC> and <MNC>) as per 3GPP TS 29.303 and is reformatted as <NI>.apn.epc.mnc<MNC>.mcc<MCC>.3gppnetwork.org For example: Alc-Wlan-APN-Name = wlangw.mnc004.mcc204.gprs |
