8) MPC-FE returns a resource modification response message to SCF(2).

9) SCF(2) forwards this response message to MAS-F.
10) MAS-F returns a streaming transfer response message to SCF(1).
11) SCF(1) forwards this streaming transfer response message to MUE. Hence, the streaming flow has
been transferred from SCF(1) to SCF(2).
9.4.2 Network initiated streaming transfer

Based on the status of an access network (for example, congestion in the network or connection released),
the network is recommended to transfer some streaming flows to another access network. The information
flow for network initiated transfer is shown as Figure 9-5.

0) An MUE has connected to multiple access networks simultaneously, and establishes several
connections to receive streaming.
1) AC-FE(1), which represents the originating access network of this transfer procedure, sends a
connection update request message to MR-FE. The message contains the identifier and the
information of the connection to be modified.
2) MR-FE updates the information of the connection based on the request message. Then MR-FE sends
a connection information message to MC-FE.
3) MC-FE sends a resource modification request message to MPC-FE, to request to revise related
transmission policy.
4) MPC-FE forwards this modification request to MAS-F.
