Description

Technical Field

[0001] The present disclosure generally relates to systems and methods for wireless communication, and more particularly to using wireless communication to prevent echo in virtual meetings.

Background Art

[0002] If virtual meeting participants do not mute their microphones themselves, echo may occur, which may disrupt the meeting for all participants. There is a need to prevent echo without requiring users to manually mute their microphones.

[0009] [Figure 7] This block diagram shows components for performing one or more of the methodologies described herein, according to one or more exemplary embodiments of the present disclosure. [Modes for carrying out the invention]

[0010] The following description and drawings adequately illustrate specific embodiments so that those skilled in the art can implement them. Other embodiments may incorporate structural, logical, electrical, process, algorithmic, and other modifications. Parts and features of some embodiments may be included in or replaced by parts and features of other embodiments. Embodiments described in the claims encompass all available equivalents of those claims.

[0011] This disclosure improves how devices authenticate and communicate with each other to avoid echoes, particularly in situations where multiple devices with the same active audio (for example, for a meeting or other communication session) are close to each other (for example, in the same room).

[0012] If participants in the same room do not mute their microphones during a conference call (e.g., a virtual meeting), it can cause echoes in the call, which can be confusing and frustrating. To prevent this and ensure smooth collaboration, users can manually mute their microphones. Echoes occur when audio received from a participant is picked up by the microphone of that same participant, or by other devices or participants in the same room.

[0013] Some existing techniques prompt users to mute their microphones and / or speakers to prevent echoes. However, existing manual solutions detract from the user experience and are not always reliable, as not all users may mute in a timely manner. Meeting participants in a room may forget to mute, and once the echo is noticed, all users in the room scramble to check their devices and mute manually. Furthermore, this echo can disrupt ongoing calls of several other users on the network. Some virtual meeting applications automatically block audio, but such solutions are application-specific and often have a low success rate.

[0014] This disclosure utilizes short-range communication, specifically Bluetooth® Low Energy (BLE) communication (as defined, for example, by the IEEE 802.15 standard), to intelligently detect and identify devices within a given room or other geographical area and automatically control their volume and / or microphones (for example, with appropriate user consent and in accordance with any applicable laws). Wireless communication can identify relevant devices in a room that have volume and / or microphones to be controlled. While multiple devices in different rooms can connect to the same Wi-Fi access point, BLE uses its short-range capability to distinguish between devices in the same room and devices in different rooms. As a result, BLE makes it possible to control the volume and / or microphones of devices in the same room without controlling devices in other rooms. Furthermore, because BLE enables high-speed connection and disconnection, as well as short-range control signals, the short range of BLE allows for improved latency compared to longer-range communication protocols such as Wi-Fi.

[0015] In one or more embodiments, the device may include a common chassis design with a notification abstraction layer (NAL) to facilitate BLE-based discovery and control. The NAL may communicate with operating system services, audiovisual devices and sensors (e.g., speakers, microphones, cameras, etc.), and software that integrates the device with other devices by using communication protocols such as Bluetooth® and Wi-Fi. The common chassis design allows any type of computer and any virtual meeting or other communication application to use the architecture to control the device's audio and / or video.

[0016] In one or more embodiments, for a given room or other location, and for a given meeting, room and meeting-based alphanumeric handles may facilitate the extended controls of this specification. For example, the alphanumeric handle may be a combination / hash created from a meeting identifier (e.g., a conference identifier) ​​and a room (or other location) identifier. The integrated software may extract the meeting identifier from a meeting / communication application and hash it with the room identifier. Each room may be assigned a primary device that can be changed, and when a participant joins a meeting (e.g., a communication session with a meeting identifier), the participant may be linked to the primary device in their respective room. The primary device in a room may be selected based on which device in the room first joins the meeting, or it may be selected randomly, or it may be selected by the user. When a primary device leaves a room, another device may be selected as the primary device in that room, randomly, based on user selection, or based on the order in which devices in that room joined the meeting.

[0017] In one or more embodiments, the primary device in a room may establish a NAL connection / channel on which an application profile can be established. For example, Table 1 below shows the unique hashes for each meeting room and their devices.

[0018] [Table 1]

[0019] Referring to Table 1 above, each primary device in each room may send BLE advertising packets containing a unique hash (Unique HASH) every 100ms (or other time intervals) that can be received by legitimate participants from each respective room. Each participant can then request authentication through an application via an LE GATT (Universal Attributes) profile, which each participant is allowed to enter after authentication. For example, valid users "A1…A14" in room A may be allowed to enter the meeting and utilize the application for service management. The unique hash for each meeting and room allows a device receiving BLE advertising packets to distinguish between packets from primary devices in the same room and packets from primary devices in other rooms, and to authenticate primary devices in the same room so that only that primary device (and not, for example, primary devices in other rooms) can control their audio and / or video. If a device in Room B responds (for example, with an authentication request) to a BLE advertising packet from a primary device in Room A, the primary device in Room A may refuse to authenticate the device in Room B instead of authenticating only devices in the same room (for example, Room A). The authentication process may allow the primary device (for example, in Room A) to identify the requester's details (for example, an email address, a user identifier such as the name of the invitee to the collaborative call) along with an alphanumeric handle. As part of the authentication and authorization process for the requesting device, the collaborative application may cross-verify the legitimacy of the user by checking that the requester is included in a list of invitees to a particular collaborative call. The use of BLE should reduce the number of devices in one room receiving BLE advertisements from a primary device in another room (for example, for short-range BLE transmission), and HASH should prevent any authentication between a primary device in one room and a controllable device in another room.

[0020] Note that the BLE advertising packets used in this specification refer to specific types of BLE packets that are transmitted on specific advertising channels (e.g., 1 MHz wide) within the Bluetooth frequency spectrum (e.g., the spectrum ranging from 2402 MHz to 2480 MHz). The BLE advertising channels are dedicated to advertising packets, in contrast to data packets. BLE advertising packets can be transmitted in time series on three advertising channels within the spectrum, based on the time interval delay between each transmission. A BLE advertising packet includes a header and a payload. In one or more embodiments, the BLE advertising notification packet of this specification that carries a unique hash may use the format of Table 2 below.

[0021]

Table 2

[0022] The header may include a hardware identifier and an alphanumeric handle for detecting the type of the hardware device and the environment (e.g., room) where the device is located. An exemplary format of the header is shown in Table 3.

[0023]

Table 3

[0024] Based on the alphanumeric handle, the device is identified when it is in a specific conference room. Thus, the notification packet is updated and shared with other devices in that room. A device that receives a BLE advertising notification packet from the same room may respond with an authentication request. When the device is authenticated, the primary device in that room may send a control command to the authenticated device to control the audio-visual settings. For example, Table 4 shows an exemplary format of the payload subfields of Table 2.

[0025] [Table 4]

[0026] As shown in Table 4, the payload of a BLE advertising packet may include commands to set audio data (e.g., volume), video data (e.g., compression level / technology), camera data (e.g., on / off), and other sensor data for the controlled device. For example, the audio data subfield may use at least 2 bits to set the volume, where 00 may correspond to mute, 01 may correspond to 5% volume, 10 may be NA, and 11 may be no change relative to the current volume. Other levels and / or commands may be signaled. Reserved bits may be used to return the volume to its original volume (e.g., after a meeting has ended) and / or to manage audio endpoints on the client and host systems (e.g., onboard speakers, microphones, Bluetooth®, earphones, headphones, etc.).

[0027] Figure 1 shows an exemplary wireless communication environment 100 for collaboration calls according to one or more exemplary embodiments of the present disclosure.

[0028] Referring to Figure 1, primary device 102 may host a collaboration session as the primary device in room 104 (or another limited geographical location). Within the same room 104, there may be several other devices that can participate in the collaboration session (e.g., device 106, device 108, device 110, device 112, device 114, device 116, etc.). The devices in room 104 may be within the BLE range 120 of primary device 102. Primary device 102 may be any device that can host virtual meetings and / or phone calls.

[0029] Referring further to Figure 1, there may be other devices (e.g., device 122) outside room 104 but within primary device 102's BLE range 120 that can receive BLE advertising packets from primary device 102. Outside room 104 and outside primary device 102's BLE range 120, there may be other devices (e.g., device 124) that may not receive BLE advertising packets from primary device 102. Devices within BLE range 120 can be identified by primary device 102 using BLE join scans. Devices within and outside BLE range 120 may or may not attempt to join the collaboration session. To advertise the collaboration session and authenticate devices requesting authentication, primary device 102 may send BLE advertising packets using the formats in Tables 2-4 and containing a unique hash according to Table 1. When a device within BLE range 120 requests authentication from primary device 102 for a collaboration session and is authenticated based on a unique hash, primary device 102 can send control signals to any authenticated device to control audio, video, etc. on the authenticated device.

[0030] Figure 2 shows an exemplary architecture 200 for wireless control of audio and video in a collaboration call, according to one or more exemplary embodiments of the present disclosure. The architecture 200 of Figure 2 may be implemented in any of the devices of Figure 1, for example, to facilitate BLE advertising, authentication for collaboration sessions, and control of authenticated devices.

[0031] Referring to Figure 2, the host device 202 may refer to the primary device 102 in Figure 1, and the client device 204 may refer to a nearby device that is not the primary device 102. The host device 202 and client device 204 may run a collaboration application 206 (for example, a virtual meeting application or other collaboration application that allows devices to communicate with each other using audio and / or video). The host device 202 and client device 204 may include an operating system (OS) and corresponding OS services 208, which may run programs such as the collaboration application 206. The host device 202 and client device 204 may include a NAL 210 that communicates with the OS services 208 and the integration module 212. The NAL 210 may facilitate BLE-based discovery and control. The integration module 212 may integrate the device with other devices by using communication protocols such as Bluetooth®, Wi-Fi, etc. The NAL 210 can communicate with audio 214 (e.g., a speaker and its volume), one or more cameras 216, and other sensors 218 to control volume, video settings and output, as well as other sensor levels and configurations. The integrated module 212 can exchange BLE packets 220, such as BLE advertising packets, authentication requests and responses, and BLE controls for audio 214, cameras 216, and / or sensors 218.

[0032] Figure 3 shows an example of a conference room with collaboration call participants in various topologies according to one or more exemplary embodiments of the present disclosure.

[0033] Referring to the example in Figure 3, three meeting rooms (for example, Room 302, Room 304, and Room 306) may host participants in the same collaboration session. For example, in Room 302, there may be devices A1, A2, A3, and A4 facing one direction from each other. In Room 304, there may be devices B1 and B2 facing one direction from each other. In Room 306, there may be devices C1, C2, and C3 facing one direction from each other. The number of rooms and devices, as well as their orientations, can vary. Not all devices in a particular room are invited to, and / or attempt to access, a collaboration session (for example, hosted by collaboration application 206 in Figure 2).

[0034] One of the devices in each room may function as the primary device 202. For each room with participants in a collaboration session, a unique hash may be generated by the collaboration application 206. Table 1 above shows exemplary alphanumeric handles created for collaboration sessions and rooms. The primary device in each room may have an alphanumeric handle, which may be included in the BLE advertisement packet. For example, if device A1 is the primary device in room 302, device A1 may send a BLE advertisement packet containing alphanumeric handles for the collaboration session and for room 302. Any device receiving the BLE advertisement packet may respond with an authentication request. However, each device in each room may contain alphanumeric handles for the collaboration session and for each room, and therefore only devices requesting authentication using the same alphanumeric handle sent by their respective primary device may be authenticated by the primary device for that collaboration session. Figure 4 shows an example of BLE advertising and authentication.

[0035] Figure 4 shows an exemplary flow of process 400 for authenticating a device for a collaboration call, according to one or more exemplary embodiments of the present disclosure.

[0036] Referring to Figure 4, primary device A1 (for example, in room A) may include an alphanumeric handle 402 for the collaboration session and room (for example, according to Table 1) in a BLE advertising packet 403 broadcast (for example, to BLE range 120 in Figure 1). The BLE advertising packet 403 may be formatted according to Tables 2-4, for example, and may be received by any device within the BLE range of primary device A1. Any device receiving the BLE advertising packet 403 may respond with an authentication request to primary device A1, provided that the requesting device has access to the collaboration application hosting the collaboration session and therefore has access to the respective alphanumeric handles for the session and each room. The authentication request may include an alphanumeric handle for the requesting device. For example, device A2 in room A may send an authentication request to primary device A1 that includes the alphanumeric handle for room A and the collaboration session. Primary device A1 may determine whether the alphanumeric handle in the authentication request 404 matches the alphanumeric handle 402. If the alphanumeric handle 402 is included in the authentication request 404, device A2 may be identified as being in room A and in the same collaboration session, and therefore primary device A1 may authenticate device A2 (406) and send an authentication response to device A2 confirming the authentication.

[0037] Still referring to Figure 4, primary device A2 may continue to periodically transmit BLE advertising packets 403 with alphanumeric handle 402. Device B1 in another room (e.g., room B) may be within the BLE range of primary device A1 and therefore may receive BLE advertising packets 403. Device B1 may respond to primary device A1 with an authentication request 408. However, when device B1 joins the collaboration session, it may be provided with an alphanumeric handle for the collaboration session and for room B, and therefore the authentication request 408 may include an alphanumeric handle for room B that does not match the alphanumeric handle 402 for room A. As a result, primary device A1 may reject device B1's authentication request 408 and send an authentication response 410 indicating authentication failure to device B1.

[0038] Figure 5 shows an exemplary network 500 of a primary device 502 that controls other devices in a collaboration call, according to one or more exemplary embodiments of the present disclosure.

[0039] Referring to Figure 5, primary device 502 may advertise a collaboration session to other nearby devices (e.g., devices 504, 506, 508, and 510) using a BLE advertising packet (e.g., BLE packet 520). BLE packet 520 may include, for example, one of the packet transmissions shown in Figure 4. BLE packet 520 may also include payload data from Table 3 to instruct other devices (e.g., once authenticated by primary device 502) to control their audio, video, etc.

[0040] Figure 6 shows a flow of an exemplary process 600 for wirelessly controlling audio and video of other devices in a collaboration call, according to one or more exemplary embodiments of the present disclosure.

[0041] In block 602, a device (for example, the collaboration device 719 in Figure 7) may identify an alphanumeric handle for the collaboration session and the location where the device is located. The device may be the primary device that joined the collaboration session based on the execution of a collaboration application, and the collaboration application may provide the alphanumeric handle. The alphanumeric handle may be a hash or other combination of the collaboration session identifier and the location identifier (for example, a room).

[0042] In block 604, the device may transmit a BLE advertising packet containing an alphanumeric handle. As long as the device is the primary device for a given location, the device may transmit BLE advertising packets periodically.

[0043] In block 606, the device may identify an authentication request received from another device that has received a BLE advertising packet. The authentication request may include an alphanumeric handle when the other device is in the same location, or it may include a different alphanumeric handle when the other device is in a different location and has a different location identifier used in the other alphanumeric handle.

[0044] In block 608, the device may determine whether to authenticate another device based on whether the authentication request contains the same alphanumeric handle (for example, indicating that the other device is accessing the same collaboration session and is in the same location as the primary device). If the other device uses a different alphanumeric handle than the one in the BLE advertising packet, in block 610, the device may reject the authentication request and notify the other device that authentication failed.

[0045] In block 612, if the authentication request contains the same alphanumeric handle as the one in the BLE advertising packet, the device may authenticate other devices. The device may include a NAL to establish an application profile through the connection with the authenticated device for the collaboration session.

[0046] In block 614, the device may cause a BLE notification packet to send instructions for controlling the audio, video, and / or other settings of other devices (for example, according to Table 4). In this way, the device may mute or lower the volume of speakers on other devices and / or mute the microphones of other devices in order to avoid echoes in the collaboration session.

[0047] Figure 7 shows a block diagram of an example machine 700 or system in which one or more of the techniques (e.g., methodologies) described herein may be performed. In other embodiments, machine 700 may operate as a standalone device or may be connected to other machines (e.g., networked). In a networked deployment, machine 700 may operate as a server machine, a client machine, or both in a server-client network environment. In one example, machine 700 may function as a peer machine in a peer-to-peer (P2P) (or other distributed) network environment. Machine 700 may be any machine capable of executing instructions (sequential or otherwise) that specify the actions to be performed by that machine, such as a personal computer (PC), tablet PC, set-top box (STB), personal digital assistant (PDA), mobile phone, wearable computer device, web appliance, network router, switch or bridge, or base station. Furthermore, although only a single machine is shown, the term “machine” should also be interpreted to include any set of machines that individually or collectively execute a set of instructions (or sets of instructions) to perform one or more of the methods described herein, such as cloud computing, software-as-a-service (SaaS), or other computer cluster configurations.

[0048] The examples described herein may include or operate on logical or multiple components, modules, or mechanisms. A module is a tangible entity (e.g., hardware) capable of performing a specified operation during operation. A module includes hardware. In one example, the hardware may be specifically configured to perform a particular operation (e.g., hardwired). In another example, the hardware may include a configurable execution unit (e.g., a transistor, circuit, etc.) and a computer-readable medium containing instructions, which configure the execution unit to perform a particular operation during operation. Configuration may be performed under the direction of the execution unit or a loading mechanism. Thus, the execution unit is communicatively coupled to the computer-readable medium when the device is operating. In this example, the execution unit may be a member of two or more modules. For example, during operation, the execution unit may be configured by a first set of instructions to implement a first module at some point in time, and reconfigured by a second set of instructions to implement a second module at a second point in time.

[0049] The machine (for example, a computer system) 700 may include a hardware processor 702 (for example, a central processing unit (CPU), a graphics processing unit (GPU), a hardware processor core, or any combination thereof), main memory 704, and static memory 706, some or all of which may communicate with each other via an interlink (for example, a bus) 708. The machine 700 may further include a power management device 732, a graphics display device 710, an alphanumeric input device 712 (for example, a keyboard), and a user interface (UI) navigation device 714 (for example, a mouse). In one example, the graphics display device 710, the alphanumeric input device 712, and the UI navigation device 714 may be touchscreen displays. The machine 700 may further include a storage device (i.e., a drive unit) 716, a signal generating device 718 (e.g., a speaker), one or more collaboration devices 719, a network interface device / transceiver 720 coupled to an antenna 730, and one or more sensors 728 such as a Global Positioning System (GPS) sensor, a compass, an accelerometer, or other sensors. The machine 700 may include an output controller 734, such as a serial (e.g., Universal Serial Bus (USB), parallel, or other wired or wireless (e.g., infrared (IR), near-field communication (NFC)) connection) for communicating with or controlling one or more peripheral devices (e.g., a printer, a card reader, etc.). The operation according to one or more exemplary embodiments of the present disclosure may be performed by a baseband processor. The baseband processor may be configured to generate corresponding baseband signals. The baseband processor may further include physical layer (PHY) and medium access control layer (MAC) circuitry and may further interface with a hardware processor 702 for generating and processing baseband signals, and for controlling the operation of the main memory 704, storage device 716, and / or one or more collaboration devices 719.The baseband processor may be located on a single wireless card, a single chip, or an integrated circuit (IC).

[0050] The storage device 716 may include a machine-readable medium 722 on which one or more sets of data structures or instructions 724 (e.g., software) that embody or utilize any one or more of the technologies or functions described herein are stored. The instructions 724 may also reside, all or at least partially, in the main memory 704, in the static memory 706, or in the hardware processor 702 while being executed by the machine 700. In one example, one or any combination of the hardware processor 702, the main memory 704, the static memory 706, or the storage device 716 may constitute a machine-readable medium.

[0051] One or more collaboration devices 719 may perform or be able to perform any of the operations and processes described above and illustrated (for example, process 600 in Figure 6).

[0052] The above is only a part of what one or more collaboration devices 719 may be configured to do, and it should be understood that other functions included throughout this disclosure may also be performed by one or more collaboration devices 719. For example, one or more collaboration devices 719 may represent at least a portion of the components in Figure 2 for a primary or client device and may perform any of the operations described in Figures 1 to 5, including process 600.

[0053] Although the machine-readable medium 722 is shown as a single medium, the term “machine-readable medium” may include a single or multiple mediums configured to store one or more instructions 724 (for example, a centralized or distributed database, and / or associated caches and servers).

[0054] Various embodiments may be implemented, all or in part, in software and / or firmware. This software and / or firmware may take the form of instructions contained in or on a non-temporary computer-readable recording medium. These instructions may then be read and executed by one or more processors to enable the execution of the operations described herein. The instructions may be in any suitable form, but are not limited to source code, compiled code, interpreted code, executable code, static code, dynamic code, etc. Such computer-readable media may include, but are not limited to, any tangible non-temporary medium for storing information in a form readable by one or more computers, such as read-only memory (ROM), random access memory (RAM), magnetic disk storage media, optical storage media, flash memory, etc.

[0055] The term “machine-readable medium” may include any medium capable of storing, encoding, or carrying instructions for execution by machine 700, causing machine 700 to execute one or more of the techniques of the Disclosure, or capable of storing, encoding, or carrying data structures used by or associated with such instructions. Non-limiting examples of machine-readable mediums may include solid-state memory, as well as optical and magnetic media. For example, a machine-readable medium with mass may include a machine-readable medium having a plurality of particles having rest mass. Specific examples of mass machine-readable mediums may include non-volatile memory such as semiconductor memory devices (e.g., electrically programmable read-only memory (EPROM) or electrically erasable programmable read-only memory (EEPROM)) and flash memory devices, magnetic disks such as internal hard disks and removable disks, magneto-optical disks, as well as CD-ROM and DVD-ROM disks.

[0056] Instruction 724 may further be transmitted or received over a communication network 726 using a transmission medium via a network interface device / transceiver 720 that utilizes any one of several transport protocols (e.g., Frame Relay, Internet Protocol (IP), Transmission Control Protocol (TCP), User Datagram Protocol (UDP), Hypertext Transfer Protocol (HTTP), etc.). Illustrative communication networks may include, among others, local area networks (LANs), wide area networks (WANs), packet data networks (e.g., the Internet), mobile telephone networks (e.g., cellular networks), conventional telephone (POTS) networks, wireless data networks (e.g., the IEEE 802.11 standard family known as Wi-Fi®, the IEEE 802.16 standard family known as WiMax®), the IEEE 802.15.4 standard family, and peer-to-peer (P2P) networks. For example, the network interface device / transceiver 720 may include one or more physical jacks (e.g., Ethernet®, coaxial, or telephone jacks) or one or more antennas for connecting to the communication network 726. For example, the network interface device / transceiver 720 may include multiple antennas for wireless communication using at least one of the following techniques: single input multiple output (SIMO), multiple input multiple output (MIMO), or multiple input single output (MISO). The term “transmission medium” shall be interpreted as including any intangible medium capable of storing, encoding, or carrying instructions for execution by machine 700, and including digital or analog communication signals or other intangible mediums for facilitating the communication of such software.

[0057] The operations and processes described and shown above may be performed or carried out in any suitable order as desired in various implementations. Furthermore, in certain embodiments, at least some of the operations may be performed in parallel. Furthermore, in certain embodiments, fewer or more operations than those described may be performed.

[0058] In this specification, the term “exemplary” is used to mean “serving as an example, illustration, or representation.” Any embodiment described herein as “exemplary” should not necessarily be construed as being preferable or advantageous to other embodiments. As used herein, the terms “computing device,” “user device,” “communication station,” “station,” “handheld device,” “mobile device,” “wireless device,” and “user equipment” (UE) refer to wireless communication devices such as cellular telephones, smartphones, tablets, netbooks, wireless terminals, laptop computers, femtocells, high data rate (HDR) subscriber stations, access points, printers, point-of-sale devices, access terminals, or other personal communications system (PCS) devices. Devices may be mobile or stationary.

[0059] As used herein, the term “communicate” is intended to include transmitting, receiving, or both transmitting and receiving. This may be particularly useful in a claim when describing an organization of data that is transmitted by one device and received by another device, but only the functionality of one of those devices is required to infringe the claim. Similarly, a bidirectional exchange of data between two devices (both devices transmitting and receiving during the exchange) may be described as “communicating” when only the functionality of one of those devices is claimed. As used herein with respect to radio communication signals, the term “communicate” includes transmitting radio communication signals and / or receiving radio communication signals. For example, a radio communication unit capable of communicating radio communication signals may include a radio transmitter for transmitting radio communication signals to at least one other radio communication unit, and / or a radio communication receiver for receiving radio communication signals from at least one other radio communication unit.

[0060] As used herein, unless otherwise specified, the use of ordinal adjectives such as “first,” “second,” “third,” etc., to describe a common subject is merely to indicate that different instances of a similar subject are being referred to, and is not intended to implicitly suggest that the subjects described in this manner must be in a given order, temporally, spatially, in rank, or in any other manner.

[0061] As used herein, the term “access point” (AP) may refer to a fixed station. Access points may also be referred to as access nodes, base stations, advanced node B (eNodeB), or any other similar terms known in the art.
