Figure I.2 – Scenario of bandwidth aggregation

I.3 Multiple UE receiving multimedia

The scenario in Figure I.3 shows that the user can use multiple UE to receive independent eMMTel services.
Media flow can be decomposed through multiple connections. In other words, a multimedia flow can be
decomposed into independent components, which can then be delivered through different paths to different UE.
Alice has a CS video call with Bob via her multi-connection mobile phone when she is walking to the office.
The voice flow is transmitted through the 2G network for better quality, while the video flow is transmitted
through the 3G network to achieve larger bandwidth. After Alice arrives, she wants to use her laptop to
receive the incoming video flow due to the laptop's larger screen and to keep the voice flow on the mobile
phone. Thus, Alice switches the incoming video media from the mobile phone to the laptop.
