10. Example of multi-service transmission

The segmentations and reassemblies performed by the various layers are summarized in figure 25 . We assume that a user is downloading a file (e.g. a web page), is receiving a VoIP communication and whose terminal receives an RRC message. The download takes place over a medium that guarantees low packet loss (bearer 1) and uses RLC in acknowledged mode. The RRC protocol does the same.

Voice over IP, on the other hand, uses RLC in unacknowledged mode. As can be seen from 25 , the whole system is transported in a single transport block (assuming the base station has sufficient capacity). The transport...
