System and method of enhancing WiFi real-time communications

摘要

Systems and methods of enhanced real-time communications between WiFi devices. In one embodiment of the present invention a method for enhanced payload protection in a WiFi system includes transmitting multiple copies of data packets in successive frame body transmissions. In another embodiment, a method for enhanced communications over a WiFi link includes examining a unit ID packet to determine a destination of a data payload when errors are detected in IP and/or MAC headers. If a destination is determined, the packet is corrected and forwarded to the device based on the unit ID determination. In another embodiment, a method for enhanced real-time communications in a WiFi network includes establishing a communications frame that includes an active timeslot, preferably based on U-APSD, for a WiFi device to use for transmission of successive audio data packets transmitted between the WiFi handset and AP.

主权项

1. A WiFi communication system, comprising:
a WiFi terminal device configured to generate a request for a real-time communication mode; and a dedicated access point device configured to establish a real-time communications between the dedicated access point device and the WiFi terminal device in response to the request for the real-time communication mode from the WiFi terminal device; wherein the real-time communications comprises a frame for data transmission between the WiFi terminal device and the dedicated access point device; wherein the frame has a fixed duration and comprises an active slot dedicated to the WiFi terminal device, a sleep period associated with the WiFi terminal device, and a command slot configured for transmission of command packets; wherein the active slot comprises one or more data packet payload, each data packet payload comprising a data packet and a unit ID packet configured to carry information that uniquely identifies the WiFi terminal device; wherein an active period dedicated to the WiFi terminal device starts at a same time in each frame of a sequence of frames; wherein the dedicated access point device is configured to arrange a second active slot associated with a second WiFi terminal device within the frame and dynamically adjust a duration of the active slot dedicated to the WiFi terminal device and a number of retries within the active slot to accommodate the second active slot for the second WiFi terminal device within the frame; wherein the dedicated access point device is configured to arrange a first wakeup time and a second wakeup time such that a change in a transmission rate between active WiFi terminal devices and the dedicated access point device is accommodated without adjusting the second wakeup time; and wherein the dedicated access point device is further configured to detect error location and specific error type in a received frame, wherein the error types include address error and non-address error.
