Three types of calls admission control methods considering seek‐bar operation

Many network devices, such as a smartphones and tablets, streaming services, YouTube Netflix, have become widespread. This causes network-bandwidth congestion, so users require stable consistent communication quality. Call admission control (CAC) has been proposed to solve these bandwidth resource problems. Some CACs in order maintain QoS. However, CAC does not assume user behaviour. If assumes some behaviour, optimal parameter derived conventional may change because traffic load by considering article that arriving types of flows are three types: narrowband flows, broadband flow without seek-bar operation, with operation. Under this assumpution, two methods single threshold or thresholds proposed. With methods, it is assumed all result the same satisfaction when accommodated network. assumption, maximum each number flows. Using call loss probability characteristics Method 1, objective function 2 modified. By using modified function, can be realised while properly accommodating who excessively rejected.
