C.3 IARP example

24.3123GPPAccess Network Discovery and Selection Function (ANDSF) Management Object (MO)Release 17TS

C.3.1 UE and network configuration

The UE has the following applications installed:

– SKP is a VoIP mobile app;

– FBK is a social media mobile app. User can also access the service via browser at FBK.com (IPv4 address W.X.Y.Z);

– VoLTE is an IMS voice mobile app; and

– NFX is a real time streaming media mobile app.

The above mobile apps are not pre-configured to use any APN. The home operator wants to use IARP to assign APNs to application flows.

100100 is the PLMN ID of the HPLMN. HPLMN has non-seamless WLAN offload with SSID="WiFi_NSWO_A".

C.3.2 Operator’s policies

HPLMN operator configures IARP for non-roaming scenario as follows:

– Route SKP and FBK traffic through NSWO between 7AM and 7PM on weekdays;

– Route SKP and FBK traffic via "internet" APN between 7PM and 7AM on weekdays, all day on weekends and anytime when NSWO is not available;

– Route VoLTE traffic via "IMS" APN; and

– Route NFX to "media" APN.

HPLMN operator configures the same IARP for roaming scenario with the following exception:

– Route NFX to "internet" APN, since roaming networks may not have "media" APN.

C.3.3 ANDSF MO configuration

Figure C.3.3.1 shows the IARP policy in the ANDSF MO configured by the H-ANDSF. IARP flow distribution rules for HPLMN are shown in figure C.3.3.2.

Figure C.3.3.1: IARP configured by H-ANDSF

Figure C.3.3.2: IARP flow distribution rules for HPLMN

IARP InterAPNRouting flow distribution rules for roaming scenario are shown in figure C.3.3.3.

C.3.4 Usage scenarios

Scenario 1

UE is in the HPLMN. The only valid IARP rule is IARP/Home, which is therefore the active rule. The UE assigns the traffic to APNs according to the IARP configured by the H-ANDSF for usage within HPLMN as configured in the IARP/Home rule.

Scenario 2

UE is in the V-PLMN. The IARP/Home rule is not valid. The UE successfully establishes connectivity with the V-ANDSF and gets the policy update but the V-ANDSF cannot provide IARP to a roaming UE. Therefore, the only valid IARP rule is IARP/Roaming, which is therefore the active rule. The UE assigns the traffic to APNs according to the IARP configured by HPLMN for usage when roaming as configured in the ISRP/Roaming IARP rule.
