A wireless access point software application, including multiple software modules, dynamically determines the interference level of each channel. The application determines that a new channel is better suited to serve an RTC/RTE application over the present channel based on the interference levels and a set of interference measure thresholds. The application automatically creates a new basic service set on the new channel and associates the RTC/RTE device running the RTC/RTE application with the new basic service set. The application further refuses to associate the RTC/RTE device with the previous channel when the interference level on the new channel remains low based on a second set of interference measure thresholds. In addition, the application allows additional RTC/RTE devices to join the new basic service set with the first RTC/RTE device when the interference level on the new channel remains low based on the second set of interference measure thresholds.

System and method for automatically switching real-time communication device to new basic service set

A computer software application running on a wireless communication device determines whether an application scenario is urgent or nonurgent, and determines whether the user state is interest, uninterested or absent. The application sends the application scenario and the user state to a wireless networking device. The wireless networking device determines the user roles of different wireless communication devices. It further adjusts priorities of data packets destined to the wireless communication device based on the application scenario, the user state and the user role when downlink to the wireless communication device is congested. The priority is decreased when the application scenario is unurgent, the user role is a listener, and the user state is uninterested or absent.

Method for prioritizing data packets based on application scenario, user state and user role

A method for determining and providing upstream directives in real-time communication over a wireless network is performed by an RTC/RTE application running on a mobile device and an access point application running on a Wi-Fi access point. The access point application determines the values of a set of upstream Wi-Fi signal quality parameters including at least one of an upstream RSSI parameter, an upstream SNR parameter, an upstream link speed parameter, and an upstream remaining bandwidth parameter of the mobile device. Each value is compared to a set of upstream thresholds to derive an upstream Wi-Fi connection quality measure. Each set of upstream thresholds includes at least two different values. The RTC/RTE application determines an upstream directive from the upstream Wi-Fi connection quality measure, and presents the upstream directive to a user in an audio or video form.

System and method for providing upstream directives based on upstream signal quality of wireless network in real-time communication

A wireless access point software application, adapted to be run within a wireless access point, classifies network data packets with classification identifiers provided by RTC/RTE devices without scanning the content of them. The wireless access point software application receives inbound and outbound packet classification identifiers from the RTC/RTE applications running on the RTC/RTE devices. The identifiers are provided to a hardware data packet classifier. The hardware data packet classifier applies the identifiers against ingress packets and egress packets respectively. Data packets of the same class are assigned with a same priority. The prioritized network data packets are scheduled for transmission based on their respective priorities. The scheduled network data packets are forwarded to respective network interfaces for transmission.

Wireless access point software application for classifying network data packets to improve packet forwarding performance

An improved Wi-Fi access point dynamically determines the interference level of each channel. The access point determines that a new channel is better suited to serve an RTC/RTE application over the present channel based on the interference levels and a set of interference measure thresholds. The access point automatically creates a new basic service set on the new channel and associates the RTC/RTE device running the RTC/RTE application with the new basic service set. The access point further refuses to associate the RTC/RTE device with the previous channel when the interference level on the new channel remains low based on a second set of interference measure thresholds. In addition, the access point allows additional RTC/RTE devices to join the new basic service set with the first RTC/RTE device when the interference level on the new channel remains low based on the second set of interference measure thresholds.
