Abstract

An RTC/RTE software application running on a mobile device and an access point software application running on a Wi-Fi access point determine and provide upstream directives in real-time communication over a wireless network. 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.

FIELD OF THE DISCLOSURE

The present invention generally relates to wireless communication, and more particularly relates to real-time communication over a wireless network. More particularly still, the present disclosure relates to a system and method for providing upstream directives based on the upstream quality measures of a wireless network in real-time communication.

DESCRIPTION OF BACKGROUND

Wi-Fi is a family of wireless networking technologies that are based on the IEEE 802.11 family of technical standards. Wi-Fi (also referred to herein as WiFi) technologies are commonly used for local area networking of electronic devices and Internet access. The electronic devices can be smartphones, tablet computers, laptop computers, desktop computers, and other types of devices. A Wi-Fi access point creates a local wireless network, and is operatively coupled to the Internet via, for example, a broadband modem. The broadband modem bridges the communication between the Wi-Fi access point and the Internet. Electronic devices access the Wi-Fi access point to access the Internet and communicate with each other. The Wi-Fi access point could also be a Wi-Fi hotspot. In such a case, the Wi-Fi hotspot can be created from, for example, a wireless access point, or a smartphone that accesses a public cellular network for accessing the Internet. The Wi-Fi hotspot can be provided by, for example, a public cellular network. As used herein, Wi-Fi access points and Wi-Fi hotspots are collectively referred to as Wi-Fi access points.
Electronic devices access the Wi-Fi network for many purposes. For instance, a mobile device (such as a smartphone, a tablet computer or a laptop computer) or a desktop computer runs a real-time communication application for audio, voice, video or both audio and video communication, such as instant messaging, voice over IP (“VoIP”), video teleconferencing, and online virtual meeting. Real-time communication (“RTC”) and Real-Time Engagement (“RTE”) (collectively referred to herein as “RTC/RTE”) are the near simultaneous exchange of information over any type of telecommunications service with negligible latency. The immediacy of RTC/RTE is critically important for users. RTC/RTE software applications can be built in compliance with, for example, the Web Real-Time Communication (“WebRTC”) framework.
An RTC/RTE software application running on a wireless networked device sends data (such as voice data, video data, text data, etc.) from the electronic device on which it is running to other electronic devices or servers. The data is sent from the electronic device to the Wi-Fi access point in the form of wireless signals, and referred to herein as upstream. The RTC/RTE software application also receives data (such as voice data, video data, text data, etc.) from other electronic devices or servers. The data is sent from the Wi-Fi access point to the electronic device in the form of wireless signals as well, and referred to herein as downstream. Downstream is received by the electronic device from the Wi-Fi access point while upstream is transmitted by the electronic device to the Wi-Fi access point.
The quality of the Wi-Fi access point's Wi-Fi signal can vary depending on the relative location, interference from other devices, conditions under which a mobile device accesses the Wi-Fi access point, and other factors. When the quality of the Wi-Fi signal is lower, the quality of users' experience (“QoE”) of the RTC/RTE application becomes lower. QoE can be described and measured by a number of parameters, such as video resolution, choppy video time, video sharpness (also known as video clarity) and choppy audio time, latency, etc.
However, the mobile device running the RTC/RTE application can only provide users the wireless connection quality information of the Wi-Fi signal for the downstream connection. It does not have information about its upstream Wi-Fi network connection quality. By design, the mobile device's transmit (“Tx”) power is much smaller that the Tx power of the Wi-Fi access point. At the same time, the Wi-Fi access point has the capability to obtain data about the mobile device's upstream wireless network signal quality.
Accordingly, it is desirable for RTC/RTE applications to dynamically and automatically detect upstream issues with Wi-Fi signal and provide upstream feedback to users of the RTC/RTE applications. In particular, it is desirable for the RTC/RTE applications to provide different types of upstream directives to users. The different types of upstream directives are based on different types of upstream issues with the Wi-Fi network obtained from the Wi-Fi access point. The upstream directives are desired to help resolving or alleviating the Wi-Fi network issues.

Turning to the Figures and to FIG. 1 in particular, an illustrative block diagram of a wireless communication network is shown and generally indicated at 100. The Wi-Fi network 100 includes a Wi-Fi access point 120 connecting to the Internet 140 via the broadband access device (such as a broadband modem) 120 or a public cellular network 130, and a set of electronic devices, such as the tablet computer 104, the laptop computer 106, the smartphone 108 and the desktop computer 110. The electronic devices 104-108 are mobile devices. The devices 104-110 each run an improved RTC/RTE software application while the Wi-Fi access point 102 runs an improved Wi-Fi access point software application.

The Wi-Fi access point 102 include an operating system 204, such as the LEDE/OpenWRT operating system, and Linux operating systems.
The improved Wi-Fi access point 102 further includes a special Wi-Fi access point software application 202 in accordance with the present teachings. The special Wi-Fi access point software application 202 is further illustrated by reference to FIG. 3. Referring now to FIG. 3 . Referring now to FIG. 3 , an illustrative block diagram of the Wi-Fi access point 102 is shown. The special Wi-Fi access point software application 202 is one or more computer software programs written in one or more computer programming languages, such as C, C++, Java, etc.
The improved Wi-Fi access point software application 202 includes an RTC/RTE communication module 302 for configuring and managing the RTC/RTE communication with the mobile devices 104-108, an RTC/RTE device management module 304 for managing the association between RTC/RTE devices and the Wi-Fi access point 102, a Wi-Fi forwarding control module 306 for priority mapping and transmitting packet based on the packet priority on the network interfaces 216-220, a Wi-Fi channel management module 308 for managing wireless communication channels and determining the optimal channels for different communication needs, a packet transmit schedule module 310 for scheduling all egress packet based on packet priority on the network interfaces 216-220, a Wi-Fi BSS management module 312 for creating and terminating BSSes, a packet classifier module 314 for configuring hardware classifier, identifying each ingress packet and setting a priority for the packet, and a bandwidth detection module 316 for determining and managing remaining bandwidth of the network interfaces 216-220.
Each of the devices 104-110 includes a processing unit, some amount of memory operatively coupled to the processing unit, a display screen operatively coupled to the processing unit, a wireless network interface operatively coupled to the processing unit and configured to communicate with the Wi-Fi access point 102, and an operating system (such as iOS, Android and Windows 10). They may each include one or more user input interfaces, such as a voice input interface, a touch panel, a mouse, a keyboard, etc. As used herein, a wireless networked device running an RTC/RTE software application is referred to as an RTC/RTE device.
Referring to FIG. 4 , an illustrative block diagram of the RTC/RTE software application running on a mobile device (such as the electronic devices 104-110) is shown and generally indicated at 402. The special RTC/RTE software application 402 is one or more software programs written in one or more computer programming languages, such as C, C++, Java, etc. The RTC/RTE application 402 communicates with the same or different RTC/RTE software applications running other remote electronic devices via the wireless network interface 420 of the mobile device. The RTC/RTE program 402 includes a set of components. In one implementation, it includes a user interaction module 404 for interacting with a user of the RTC/RTE software application 402, a Wi-Fi device management module 406 for accessing and managing the wireless network device 420, an Wi-Fi access point communication module 408 for configuring the wireless connection and exchanging data with the Wi-Fi access point 102, and one or more RTC/RTE modules 410 for providing real-time communication functionality, such as video and audio modules.
The special RTC/RTE application 202 and the special Wi-Fi access point application 202 cooperate for determining the RTC/RTE application's 202 upstream connection issues to provide upstream directives to a user. The interaction between them is further illustrated by reference to FIG. 5 . Referring now to FIG. 5 , a sequence diagram illustrating the process by which the special RTC/RTE application 202 determines its upstream wireless network quality issues is shown and generally indicated 500.
At 502, the new access point application 202 creates a socket with a predetermined TCP port or an UDP port, binds the socket to an Internet Protocol (“IP”) address of the Wi-Fi access point 102, and listens on the socket for connection requests from the RTC/RTE application 402. TCP stands for Transmission Control Protocol while UDP stands for User Datagram Protocol. At 504, the RTC/RTE application 402 attempts to connect to the socket. Connection request to this particular socket indicates that the software application 402 is an RTC/RTE software application and the device 402 is an RTC/RTE device. At 506, the access point application 202 accepts the connection request and establishes a connection between the special applications 202 and 402.
At 508, the improved access point application 202 determines the values of a set of upstream connection quality parameters of the mobile device running the RTC/RTE application 402. The set of values cannot be obtained by RTC/RTE application 402 from the electronic device it is running on. Instead, they can only be obtained by the Wi-Fi access point 102. Each value corresponds to a parameter within the set of parameters. In one implementation, the element 508 is periodically performed. Alternatively, the element 508 is triggered by a request from the RTC/RTE application 402 or a different event. The set of upstream connection quality parameters includes, for example, an upstream RSSI parameter, an upstream SNR parameter, an upstream link speed parameter, and an upstream remaining bandwidth parameter. RSSI stands for Received Signal Strength Indicator measuring the power level of upstream wireless signal of the mobile device that is received by the access point 102. SNR stands for Signal to Noise. In one implementation, remaining bandwidth is measured per network interface.
At 510, the Wi-Fi access point application 202 sends the set of values to the RTC/RTE application 402 over the socket. At 512, the RTC/RTE application 402 receives the set of values, and determines a set of upstream connection quality measures from the set of values. The determination is further illustrated by reference to FIG. 7 . Turning now to FIG. 7 , a flowchart illustrating the process by which the RTC/RTE application 402 determines the set of upstream connection quality measures is shown and generally indicated at 700. At 702, the RTC/RTE application 402 determines an upstream RSSI quality measure by comparing the upstream RSSI value within the set of values to a set of upstream RSSI thresholds. For example, the set of upstream RSSI thresholds includes −80 dBm and −65 dBm. When the upstream RSSI value is less than the threshold −80 dBm, the upstream RSSI quality measure is set to, for example, low. When the upstream RSSI value is bigger than the threshold −65 dBm, the upstream RSSI quality measure is set to, for example, high.
At 704, the RTC/RTE application 402 determines an upstream SNR quality measure by comparing the upstream SNR value within the set of values to a set of upstream SNR thresholds. For example, the set of upstream SNR thresholds includes 15 dB and 30 dB. When the upstream SNR value is less than the threshold 15 dB, the upstream SNR quality measure is set to, for example, low. When the upstream SNR value is bigger than the threshold 30 dB, the upstream SNR quality measure is set to, for example, high.
At 706, the RTC/RTE application 402 determines an upstream link speed quality measure by comparing the upstream link speed value within the set of values to a set of upstream link speed thresholds. For example, the set of upstream link speed thresholds includes two (2) and four (4). When the upstream link speed value is less than the threshold of two times the required bandwidth, the upstream link speed quality measure is set to, for example, low. When the upstream link speed value is bigger than the threshold of four times the required bandwidth, the upstream link speed quality measure is set to, for example, high. The required bandwidth is the bandwidth required by the RTC/RTE application 402 to achieve an acceptable level of QoE, and is measured in Mbps (standing for megabits per second). The required bandwidth is determined by a number of factors, such as the video frames per second, resolution of the video of the RTC/RTE application 402, the number of channels of the RTC/RTE communication.
Alternatively, the set of upstream link speed thresholds includes percentage values, such as 25 and 75. In such a case, when the upstream link speed value is less than 25% of the maximum link speed, the upstream link speed quality measure is set to, for example, low; and when the upstream link speed value is bigger than 75% of the maximum link speed, the upstream link speed quality measure is set to high.
At 708, the RTC/RTE application 402 determines an upstream remaining bandwidth quality measure by comparing the upstream remaining bandwidth value within the set of values to a set of upstream remaining bandwidth thresholds. For example, the set of upstream remaining bandwidth thresholds includes two (2) and four (4). When the upstream remaining bandwidth value is less than the threshold of two times the required bandwidth, the upstream remaining bandwidth quality measure is set to, for example, low. When the upstream remaining bandwidth value is bigger than the threshold of four times the required bandwidth, the upstream remaining bandwidth quality measure is set to, for example, high. The remaining bandwidth is the bandwidth of the present wireless channel between the mobile device and the access point 102 that is still available for data transmission, and is measured in Mbps.
Turning back FIG. 5 , at 514, the RTC/RTE application 402 determines a set of upstream directives based on the set of upstream connection quality measures. The determination is further illustrated by reference to FIG. 6 . Turning now to FIG. 6 , a flowchart illustrating a process by which the RTC/RTE application 402 determines the set of upstream directives is shown and generally indicated at 600. At 602, the RTC/RTE application 402 determines that one of the upstream RSSI quality measure, the upstream SNR quality measure, and the upstream link speed quality measure is low. In such a case, at 604, the RTC/RTE application 402 determines a first upstream directive. The first upstream directive is, for example, “move closer to the Wi-Fi access point.”
At 606, the RTC/RTE application 402 determines that one of the upstream remaining bandwidth quality measure is low. In such a case, at 608, the RTC/RTE application 402 determines a second upstream directive. The second upstream directive is, for example, “too many applications require Wi-Fi network bandwidth.”
Turning back to FIG. 5 , at 516, the RTC/RTE application presents the set of upstream directives to a user. Oftentimes, the set of upstream directives likely contains only one upstream directive. The set of upstream directives is presented to the user through, for example, a voice output, a video indicator on the display screen of the mobile device, or a text display on the display screen of the mobile device. The voice output is of an audio format while the video indicator and the text display are of video formats. In a different implementation, the element 512 is performed by the improved access point application 202 at 518. In such a case, at 520, the set of upstream connection quality measures is sent to the RTC/RTE application 402 through the socket.
