This paper proposes new scheduling algorithms for
best effort (
BE) traffic classification in business
femtocell networks. The purpose of traffic classification is to provide differentiated services to
BE users depending on their traffic classes, and the concept of traffic classification is called Inter User Best Effort (
IUBE) in

Evolution Data Optimized (
EVDO) standard. Traffic differentiation is achieved by introducing
Grade of Service (
GoS) as a quality of service (QoS) parameter into the scheduler's
decision metric (
DM). New scheduling algorithms are called
QoS Round Robin (
QoS-RR),
QoS Proportionally Fair (
QoS-PF),
QoS maximum data rate control (
DRC) (
QoS-maxDRC),
QoS average
DRC (
QoS-aveDRC),
QoS exponent
DRC (
QoS-expDRC),
QoS maxDRC-PF (
QoS-maxDRC-PF). Two different
femtocell throughput experiments are performed using real
femtocell devices in order to collect real
DRC values. The first experiment examines 4, 8, 12 and 16
IUBE users, while second experiment examines 4
IUBE + 2 Voice over IP (
VoIP), 8 IUBE + 2
VoIP, 12
IUBE + 2
VoIP, 16
IUBE + 2 (
VoIP) users. Average sector throughput,
IUBE traffic differentiation,
VoIP delay bound error values are investigated to compare the performance of the proposed scheduling algorithms. In conclusion,
QoS-maxDRC-PF scheduler is proposed for business
femtocell environment.
