Abstract
This paper describes a Call Admission Control (CAC) mechanism
that adapts the type of admitted users based on a
proposed resource allocation strategy that responds to changes
in the channel conditions. The admission control decides to
admit new services according to the load of the cell and based
on a-priori analysis of the radio link for the incoming request
in terms of QoS satisfaction. For low to medium values of
the load the Resource Allocation (RA) grants resources to
user with higher priority. The priority is defined based on
user and service characteristics. For very high load values the
mechanism will aim at maximising the number of users that
receive a connection even the QoS for high priority users must
be degraded.
