Virtual Access Point Configuration Method Considering Uplink Communications

In recent years, high-performance mobile terminals have become widespread, and the amount of mobile data traffic has increased rapidly. For this reason, expectations for bandwidth guaranteed services are increasing. The existing method that makes virtual AP for each BE (Best Effort) service and GBR (Guaranteed Bit Rate) service receives much attention. It dynamically changes the physical AP assigned to each virtual AP, thereby keeping the call blocking probability GBR users below the target value and improving the satisfaction of BE users. However, it considers downlink traffic only. In uplink communications, some packet losses due to CSMA/CA decrease the effective throughput. This results in the misestimation of reserved bandwidth. This paper extends the existing method to consider uplink communications.
