1. A method of handling a call to or from a mobile terminal over a wireless link to a base station connected to a communications
network, comprising:
when setting up the call, determining a maximum bandwidth allocation for the call; and
during the call, varying the current bandwidth allocation for the call over the wireless link in accordance with a variable
bandwidth demand relating to the call without exceeding said maximum bandwidth allocation,
wherein the current bandwidth allocation includes a forward bandwidth allocation, the forward bandwidth allocation being varied
during the call in accordance with a forward channel demand relating to the call, the method further comprising transmitting
from the base station to the mobile terminal using the forward bandwidth allocation; and
wherein the forward channel demand is derived from the quantity of buffered data received from the network for transmission
to the mobile terminal.
