摘要：A system and method are provided in which access point (AP) devices in awireless local area network (WLAN) are typed or configured into one of three
measurement and reporting roles: Monitor-Mode AP (MMAP), Portal AP (PAP), a BorderAP (BAP) or an Interior AP (IAP). APs are assigned specific link measurement
requirements according to their assigned type or role. In general, MMAPs and PAPs havethe greatest measurement and reporting responsibilities, BAPs have less measurementand reporting responsibilities than PAPs and IAPs have the least measurement andreporting responsibilities. The APs generate measurements that are supplied toappropriate equipment to facilitate handover decisions with respect to a dual-modewireless client device that roams between the WLAN and another network or vice versa.As a result, link measurements are only performed by APs in locations where suchmeasurements are necessary for handover service, thus reducing the overall processingload on the WLAN infrastructure.
