Wireless communication system, access point and wireless station composing the wireless communication system, and communication load balancing method for access point

摘要

To reduce load on an access point even if a large number of wireless stations are located very close to the access point. An access point detects a communication load value (S1 and S2) and reports it to wireless stations (S3). The access point waits for a predetermined time after the transmission of the communication load value (5) and detects a communication load value again (S6 and S7). The access point determines whether the first communication load value is larger than a predetermined value K (S4) and whether the second communication load value is larger than K (S8). If the first and second communication load values are larger than K, the access point outputs a warning output command instructing the wireless stations to output a warning prompting their users to move away from their current locations (S9).
