Figure I.2 – Video conference service

Alice has to attend a video conference with business partners via her mobile phone when she is walking to
the office. On the way to her office, some WLAN hotspots are available. So Alice decides to initiate the video
flow through a WLAN link in order to benefit from higher bandwidth and cheaper cost, whereas she sends
and receives the audio flow through the 2G/3G link in order to guarantee the audio flow to be uninterrupted.

I.3 Real-time monitor services
Real-time monitor services mainly include real-time monitor, multi-viewer service and so on. A real-time
monitor service collects multimedia streaming from multiple terminals, and distributes to one or more UE
after process by the service. Users can view the multimedia information in one screen from different angles
or locations.
In the environment of multi-connection, the advantages of multi-connection, such as flexibility in network
selection, transparency of multi-connection, service continuity, increased access options, can be used to
enhance this kind of service. For example, benefiting from multi-connection technology, multiple terminals
are able to send multimedia flows through different connections. After integration by the service, these
multimedia flows are distributed to one or more UE. Both transmission efficiency and user experience can
be improved in this way. Figure I.3 is an example of real-time monitor service.

Figure I.3 – Real-time monitor service

Alice is watching a linear broadcast of a baseball game. There are multiple cameras in the stadium, which
provide different views of the game. All views are delivered to Alice's terminal through multiple networks.
Then Alice is able to choose and watch the preferred view.

With multi-connection technology, multi-view service is able to deliver video streaming from different video
sources simultaneously. An end-user can choose the views that he or she would like to watch. It will greatly
improve user experience in this way.
