Fig. 11 shows the served rate of multislot services with
resource allocation sclzeme-2 distributed with call arrival rate
for the average message size of 2~13.4 kb and 5~13.4 kb
respectively. The solid lines are used for an average message
size of 2~13.4 kb and dashed lines for an average message
size of 5~13.4 kb. For the traffic with the same average
message size, the served rate for the same type of multislot
service is almost same even though those traffics have
different percentage of niultislcit service traffics. The served
rate decreases as the increment of call arrivals and the average
traffic size. Therefore, the resclurce allocation scheiize-2 not
only can reduce the blocking probability and delay caused by
multislot services, but also can adapt to the GPRS traffic to
provide the optimal performance: to the network
