Those simulations show that the higher blocking probability
and longer delay caused by multislot services could be
reduced by using a flexible multislot service scheme. The
protocol of a flexible multislot service scheme is:
1420
on the arrival of a multislot call,
- if the available resource is enough to provide its required
service, the call is allowed to transmit its required rate;
- if the available resource is not enough to provide its
required service, the network negotiates with the call to
reduce its transmitted rate to the value which the network
can provide;
- if the call agrees to transmit with the rate which the network
can provide, the network further inquires the call if it wants
to restore its required transmission rate when the network
can provide;
- if the call does not agree to reduce its transmission rate, put
it into the queue until the network can provide its required
transmission rate.
