B.4 Example 3 without media components.

29.2143GPPPolicy and charging control over Rx reference pointRelease 17TS

The UE and AF do not exchange SDP for an application and do not share an algorithm, which guarantees that UE and AF assign the same ordinal number to each media component.

At the AF session initiation, the UE and AF agree to set up the following IP flows:

– Uplink UDP flow with destination port 100.

– Downlink UDP flow with destination port 100.

– Downlink TCP flow with destination port 100.

– Uplink TCP flow with destination port 100.

– Uplink UDP flow with destination port 200.

The following binding info is assigned to these IP flows.

– Uplink UDP flow with destination port 100: (0, 2)

– Downlink UDP flow with destination port 100: (0, 5)

– Downlink TCP flow with destination port 100: (0, 4)

– Uplink TCP flow with destination port 100: (0, 1)

– Uplink UDP flow with destination port 200: (0, 3)

At a later stage in the session, the TCP IP flows are removed and the following IP flows are added:

– Uplink UDP flow with destination port 150.

– Downlink UDP flow with destination port 50.

The following binding info is assigned to the IP flows existing at this stage:

– Uplink UDP flow with destination port 100: (0, 2)

– Downlink UDP flow with destination port 100: (0, 5)

– Uplink UDP flow with destination port 200: (0, 3)

– Uplink UDP flow with destination port 150: (0, 6)

– Downlink UDP flow with destination port 50: (0, 7)
