International Classification:

H04W 36/08

H04W 4/00

US Classification:

370331, 370338, 4554321

Abstract:

A system and method are provided in which access point (AP) devices in a wireless local area network (WLAN) are typed or configured into one of three measurement and reporting roles: Monitor-Mode AP (MMAP), Portal AP (PAP), a Border AP (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 have the greatest measurement and reporting responsibilities, BAPs have less measurement and reporting responsibilities than PAPs and IAPs have the least measurement and reporting responsibilities. The APs generate measurements that are supplied to appropriate equipment to facilitate handover decisions with respect to a dual-mode wireless 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 such measurements are necessary for handover service, thus reducing the overall processing load on the WLAN infrastructure.

International Classification:

H04W 48/16

US Classification:

370328

Abstract:

In an example embodiment, an access point or wireless local area network controller programs an opaque cookie into a wireless client. The cookie carries association detail and current traffic information of the client. When the client roams to a new access point, the client presents the cookie to the new access point.

International Classification:

H04W 28/02

US Classification:

370235

Abstract:

In one embodiment, a method includes performing stateful application classification on packets received at a controller and transmitting classification information to an access point. The classification information includes flow information and stateless rules for applying policies. The access point is configured to use the classification information to perform stateless application classification and apply policies to packets received from a mobile device. An apparatus and logic are also disclosed herein.
