Abstract: Systems and method for wireless roaming include operating, via a wireless communication device, a first communication link between the wireless communication device and a first access point using a first media access control (MAC) layer of the wireless communication device; initiating, using a second MAC layer of the wireless communication device, a roaming handover with a second access point while the first communication link remains configured for transmitting and receiving application and/or IP layer communication packets; ceasing transmission and reception of the application and/or IP layer communication packets via the first communication link after the roaming handover has been initiated; and resuming transmission and reception of the application and/or IP layer communication packets with a second communication link between the wireless communication device and the second access point upon completion of the roaming handover.

Abstract: A method in a client device of mitigating connection impact on service infrastructure includes: prior to initiating a connection to a service, generating an impact indicator corresponding to the service, the impact indicator representing a predicted load at the service; determining whether the impact indicator exceeds an impact threshold; when the impact indicator exceeds the impact threshold, incrementing a connection interval according to a backoff interval; and initiating a connection with the service upon expiry of the connection interval.

Abstract: A client device and method for analysis of a predetermined set of parameters associated with a radio coupling to a WLAN is provided. The client device includes a memory and a radio coupled to at least one processor. The at least one processor executes in the memory a first client Wireless Local Area Network (WLAN) stack having a plurality of layers configured to couple the radio to a WLAN. The at least one processor also executes in the memory a second client WLAN stack emulating the plurality of layers of the first client WLAN stack. The at least one processor is configured to receive, at the second client WLAN stack, data from the plurality of layers of the first client WLAN stack and analyze a predetermined set of WLAN parameters of the client device based on the data received from the plurality of layers of the first client WLAN stack.

Abstract: A system for monitoring wireless communications in a client device includes a wireless communications interface, including: an analyzer; a monitoring controller coupled to the analyzer; an operational controller of the client device coupled to the wireless communications interface, the operational controller configured to: control the wireless communications interface to establish a wireless connection with an access point according to a set of connection parameters including a channel identifier; and transmit the set of connection parameters to the monitoring controller; the monitoring controller configured, responsive to receiving the connection parameters from the operational controller, to: monitor a channel corresponding to the channel identifier to obtain a plurality of frames transmitted over the channel; and provide the plurality of frames to the analyzer.

Abstract: A notification framework for access point controllers is provided. An access point controller receives, from a device, a request for an application token associated with an application at the device, the application token configured to identify messages to the application when transmitted therewith. The access point controller transmits, to the device, the application token. When the device is to communicate with an applications server associated with the application, the device transmits the application token to the applications server, which transmits messages for the application to the access point controller which transmits the messages, with the application token, to the device. In response, the device can provide a notification of the message, and/or the device can establish a connection with the application server, at least temporarily.
