Bearer QoS Mgmt vs.
IP Flow Bandwidth Mgmt
› Bearer QoS management
– can be managed in the whole GPRS network
(i.e. Packet Core + RAN)
– can act as a flag and works in case of actual network congestion
– has no effect on the service performance as long as there is no
network congestion
– preserves scarce resources when they get limited
› IP flow bandwidth management
– acts on the single IP flow (i.e. service) independently of the actual
congestion in the network
– has an immediate impact on the service performance
– tries to avoid scarce resources becoming congested
