Description

IP-CAN-Type

The IP-CAN-Type AVP (AVP code 1027) is of type Enumerated, and it shall indicate the type of Connectivity Access Network in which the user is connected.

The IP-CAN-Type AVP shall always be present during the IP-CAN session establishment. This AVP is included in a CCR-Initial message.

The following values are defined in 3GPP TS 29.212:

3GPP-GPRS (0)

This value shall be used to indicate that the IP-CAN is associated with a 3GPP GPRS access that is connected to the GGSN based on the Gn/Gp interfaces and is further detailed by the RAT-Type AVP. RAT-Type AVP will include applicable 3GPP values, except EUTRAN.
DOCSIS (1)

This value shall be used to indicate that the IP-CAN is associated with a DOCSIS access.
xDSL (2)

This value shall be used to indicate that the IP-CAN is associated with an xDSL access.
WiMAX (3)

This value shall be used to indicate that the IP-CAN is associated with a WiMAX access (IEEE 802.16).
3GPP2 (4)

This value shall be used to indicate that the IP-CAN is associated with a 3GPP2 access connected to the 3GPP2 packet core as specified in 3GPP2 X.S0011 [20] and is further detailed by the RAT-Type AVP.
3GPP-EPS (5)

This value shall be used to indicate that the IP-CAN associated with a 3GPP EPS access and is further detailed by the RAT-Type AVP.
Non-3GPP-EPS (6)

This value shall be used to indicate that the IP-CAN associated with an EPC based non-3GPP access and is further detailed by the RAT-Type AVP.

NOTE:

For NetEngine 8000 F, the value range of IP-CAN-Type AVP is as follows:

xDSL (2)

This value shall be used to indicate that the IP-CAN is associated with an xDSL access.
WLAN (1050)

This value shall be used to indicate that the IP-CAN is associated with a WLAN access.

For WiFi users, the IP-CAN-Type AVP is set to WLAN. In other modes, the IP-CAN-Type AVP is set to XDSL.

The PCRF determines a policy for users based on the IP-CAN-Type AVP. The policy used varies with the access mode. When the access mode changes, the PCEF sends a message carrying a new access mode and the IP_CAN_CHANGE trigger. The message requests that the PCRF deliver a relevant policy so that the PCEF can implement policy control based on the access mode.
