Technical Field

[0003] With the development of communication technology, electronic devices support the use of multiple wireless communication protocols to establish communication links, such as Wi-Fi, Bluetooth, and StarFlash communication protocols. However, due to the limitations of internal space and production costs, it is usually impossible to set up too many antennas inside electronic devices. Therefore, in electronic devices, multiple communication links established according to different communication protocols may time-division multiplex the same antenna when communicating at the same time, that is, use the same antenna in turn. It can be understood that since different communication links have a competitive relationship when time-division multiplexing the same antenna, the electronic device may not be able to take into account the communication quality of each communication link, resulting in a poor user experience.

[0007] In a first aspect, an embodiment of the present application provides a communication link management method, which is applied to a first electronic device, where the first electronic device is connected to a second electronic device via a first communication link and to a third electronic device via a second communication link. The method includes: using the first communication link and the second communication link to communicate simultaneously; wherein the first communication link and the second communication link have time-division multiplexing antennas, and the communication protocols used by the first communication link and the second communication link are different; and managing the first communication link according to the connection parameters of the second communication link so that the first communication link and the second communication link after management do not have time-division multiplexing antennas.

[0053] The technical solutions provided in the embodiments of the present application are described below with reference to the accompanying drawings.

[0054] It should be understood that in the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is merely a way to describe the association relationship of associated objects, indicating that three relationships can exist, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0055] In this embodiment, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this embodiment, unless otherwise specified, "plurality" means two or more.

[0056] For the sake of convenience, some terms involved in this application are explained below.

[0057] (1) Wireless communication protocol

[0058] A wireless communication protocol is a communication standard for connecting electronic devices to wireless networks, referred to as a communication protocol. In this embodiment, the wireless communication protocols include but are not limited to wireless fidelity (Wi-Fi) 2.4G, Wi-Fi 5G, classic Bluetooth (BT), Bluetooth low energy (BLE), SparkLink Basic (SLB), SparkLink Low Energy (SLE), ZigBee, etc. Among them, the communication frequency bands of the Wi-Fi 2.4G communication protocol, BT communication protocol, SLE communication protocol, and ZigBee communication protocol are basically around 2.4GHz, and the communication frequency band of the Wi-Fi 5G communication protocol is around 5GHz.

[0059] (2) Wireless communication link

[0060] A wireless communication link is a link established between electronic devices based on a wireless communication protocol, referred to as a communication link or link. Electronic devices can establish different types of communication links based on different wireless communication protocols. For example, electronic devices can establish different types of communication links such as Wi-Fi 2.4G links, Wi-Fi 5G links, BT links, BLE links, SLB links, SLE links, and ZigBee links based on the above-mentioned communication protocols such as Wi-Fi 2.4G, Wi-Fi 5G, BT, BLE, SLB, SLE, and ZigBee. The embodiments of the present application do not limit the specific types of communication protocols and communication links used in the communication process of electronic devices.

[0061] (3) SISO links and MIMO links

[0062] In this embodiment, the communication links include single-input single-output (SISO) links and multiple-input multiple-output (MIMO) links, depending on the number and form of data transmission paths within the communication links. Each type of link is described below.

[0063] A SISO link is a single-transmit, single-receive link. For example, as shown in Figure 1A, in a SISO link, the transmitter provides a transmit antenna, the receiver provides a receive antenna, and the path between the transmit and receive antennas is unique. As can be understood, since a SISO link has only one data transmission path, its communication rate is typically limited.

[0064] A MIMO link is a multi-transmit, multi-receive link. For example, as shown in Figure 1B , in a MIMO link, the transmitter provides at least two transmit antennas, such as transmit antenna 1 and transmit antenna 2; the receiver provides at least two receive antennas, such as receive antenna 1 and receive antenna 2. Based on this, the MIMO link can include: sub-link 1 between transmit antenna 1 and receive antenna 1, and sub-link 2 between transmit antenna 1 and receive antenna 2. A sub-link is a data transmission path.

[0065] It should be noted that because a MIMO link has multiple sub-links, electronic devices can use these sub-links to transmit data simultaneously when communicating over the MIMO link. Therefore, MIMO links can improve system capacity, coverage, and signal-to-noise ratio, thereby increasing communication rates, without increasing occupied bandwidth.

[0066] Taking the MIMO link with two sub-links shown in Figure 1B as an example, when an electronic device communicates using this MIMO link, it typically divides the data to be transmitted into two parts and sends them simultaneously via sub-link 1 and sub-link 2. After the receiving end receives the data from these two sub-links, it integrates the data to obtain the complete data. However, if an anomaly occurs in one of the sub-links in the MIMO link, the receiving end will lose one channel of data, thus affecting the transmission performance of the entire communication link.

[0067] (4) Multiplexing technology

[0068] Multiplexing technology is used to transmit multiple signals using limited transmission resources. Multiplexing technologies include, but are not limited to, time division multiplexing (TDM) and frequency division multiplexing (FDM). The details are as follows.

[0069] Time division multiplexing (TDM) divides time into multiple time slots, each used to transmit a single signal. Each signal is transmitted in its assigned time slot, and different time slots are used to distinguish different signals. The receiver analyzes and recovers the original signal based on the time slots. Time division multiplexing is suitable for scenarios with high real-time requirements, such as telephone communications and data transmission.

[0070] Frequency division multiplexing (FDM) divides the available spectrum into multiple non-overlapping subcarrier bands, each used to transmit a single signal. Each signal is transmitted on its assigned frequency band, with different frequency bands used to distinguish different signals. The receiver analyzes and recovers the original signal based on the frequency bands. Frequency division multiplexing is suitable for scenarios with relatively low signal bandwidth requirements, such as television broadcasting and radio communications.

[0071] In short, time-division multiplexing (TDM) separates signals by using different time slots, while frequency-division multiplexing (FDM) separates signals by using different frequency bands. They differ in their signal transmission methods and application scenarios, and the choice of technology depends on specific communication requirements and resource constraints.

[0072] Based on the above description, the technical solutions provided in the embodiments of the present application are explained in detail below.

[0073] With the development of communication technology, an electronic device can establish multiple different communication links with multiple other electronic devices based on different communication protocols to form a multi-link communication system.

[0074] Figure 2 is a schematic diagram of the structure of a communication system provided by an embodiment of the present application. The communication system includes a first electronic device, a second electronic device, a third electronic device, a fourth electronic device, etc., wherein the first electronic device and the other electronic devices are connected via the same or different communication links. For example, the first electronic device and the second electronic device are connected via communication link 1, the first electronic device and the third electronic device are connected via communication link 2, and the first electronic device and the fourth electronic device are connected via communication link 3. In addition, electronic devices other than the first electronic device may be connected or not connected. This embodiment does not limit the types of each communication link in the communication system, nor does it limit the number of electronic devices in the communication system.

[0075] In this embodiment, the electronic device may be a mobile phone, a tablet computer, a wearable device (such as a smart watch), an in-vehicle device, an augmented reality (AR) / virtual reality (VR) device, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), or other terminal devices. It may also be a peripheral device such as a mouse, a keyboard, a stylus, a speaker, or a router, a gateway device, etc. The embodiments of the present application do not limit the specific type of the electronic device.

[0076] In one example, as shown in FIG3A , in this communication system, the first electronic device is a tablet computer, the second electronic device is a router, and the third electronic device is a stylus. On the one hand, the tablet computer is connected to the router via a Wi-Fi link to upload / download audio and video, pictures, files, web page data, etc.; on the other hand, the tablet computer is connected to the stylus via an SLE link to receive the pressure data of the screen fed back by the stylus. It should be noted that when a user uses a stylus to write on the screen of an electronic device (such as a tablet computer, mobile phone, etc.), the tip of the stylus will exert a certain amount of pressure on the screen, and the value of the pressure is the pressure data. The pressure data is usually detected by the stylus and sent to the electronic device. The tablet computer can display the handwriting of the stylus based on the movement trajectory of the stylus on the screen and the pressure data. Generally speaking, the greater the pressure of the stylus on the screen, the thicker the handwriting displayed on the tablet computer; conversely, the less pressure the stylus exerts on the screen, the thinner the handwriting displayed on the tablet computer.

[0077] In another example, as shown in Figure 3B, in this communication system, the first electronic device is a tablet, the second electronic device is a router, and the third electronic device is a Bluetooth headset. On the one hand, the tablet connects to the router via a Wi-Fi link to upload / download audio, video, images, files, and webpage data; on the other hand, the tablet connects to the Bluetooth headset via a BT link and transmits high-definition audio to the Bluetooth headset for the user to listen to.

[0078] Figure 4 is a schematic diagram of the structure of an electronic device provided in an embodiment of the present application. The electronic device includes multiple wireless communication modules and multiple antennas. The communication protocols used by each wireless communication module can be the same or different. The operating frequencies of each antenna can be the same or different. Furthermore, each communication module is connected to an antenna adapted for the communication frequency band used by its communication protocol.

[0079] Exemplarily, the multiple communication modules include wireless communication modules 1 to wireless communication modules 6, and the multiple antennas include antennas 1 to antennas 3. These communication modules can be Wi-Fi 2.4G communication modules, Wi-Fi 5G communication modules, BT communication modules, BLE communication modules, SLB communication modules, SLE communication modules, ZigBee communication modules, etc. The operating frequency of each antenna can be 2.4GHz, 5GHz, etc., which is not limited in this embodiment. These wireless communication modules can be understood as the core in the corresponding communication chip. For example, the Wi-Fi 2.4G communication module is the Wi-Fi 2.4G Core, and the Wi-Fi 5G communication module is the Wi-Fi 5G Core.

[0080] It should be noted that, although not shown in the figure, the electronic device may include other components in addition to the above-mentioned wireless communication module and antenna, such as a processor, an external memory interface, an internal memory, a universal serial bus (USB) interface, a charging management module, a power management module, a battery, other antennas, other wireless communication modules, a mobile communication module, an audio module, a speaker, a receiver, a microphone, a headphone jack, various sensor modules, buttons, a motor, an indicator, a camera, a display, and a subscriber identification module (SIM) card interface, etc. One or more of the above. The structure illustrated in the embodiment of the present application does not constitute a specific limitation on the electronic device.

[0081] Currently, due to internal space and production cost constraints, electronic devices typically cannot accommodate multiple antennas. Therefore, when different wireless communication modules are operating simultaneously, they may use a single antenna to transmit and receive signals, or they may reuse the same antenna. Reusing the same antenna by different wireless communication modules includes time-division multiplexing and frequency-division multiplexing.

[0082] For example, as shown in Figure 4, wireless communication modules 1 and 2 are connected to antenna 1 via a switch. When wireless communication modules 1 and 2 are operating simultaneously, antenna 1 is time-division multiplexed. Furthermore, wireless communication module 3 is connected to a mixer, and wireless communication modules 4 and 5 are first connected to the switch, then to the mixer via the switch, which is then connected to antenna 2. It can be understood that when wireless communication modules 4 and 5 are operating simultaneously, antenna 2 is time-division multiplexed. When wireless communication modules 3 and either wireless communication module 4 or wireless communication module 5 are operating simultaneously, antenna 2 is frequency-division multiplexed with either wireless communication module 3 or wireless communication module 4 or 5. Wireless communication module 6 is connected separately to antenna 3.

[0083] However, when time-division multiplexing the same antenna, various wireless communication modules compete with each other. As you can see, as one wireless communication module spends more time using the antenna, its data transmission rate increases, and communication quality improves accordingly. However, another wireless communication module spends less time using the antenna, and communication quality degrades. Therefore, in some communication scenarios where time-division multiplexing antennas is used, electronic devices may not be able to balance the communication quality of different communication links, resulting in a poor user experience.

[0084] Taking a tablet as an example, as shown in Figure 5, the tablet's optoelectronic multiplexing connection chip (i.e., Connectivity Combo chip) includes a first Wi-Fi 2.4G module (Wi-Fi Core0), a second Wi-Fi 2.4G module (Wi-Fi Core1), a BT module, an SLE module, and a first antenna ant0 and a second antenna ant1. The first and second Wi-Fi 2.4G modules support communication via the Wi-Fi 2.4G protocol, and both the first and second antennas are 2.4GHz antennas.

[0085] The first Wi-Fi 2.4G module and the BT module are connected to the first antenna via a first switch. Specifically, when the first Wi-Fi 2.4G module uses the first antenna, the electronic device controls the first switch to connect the first Wi-Fi 2.4G module and the first antenna so that the first antenna can transmit and receive Wi-Fi 2.4G signals. When the BT module uses the first antenna, the electronic device controls the first switch to connect the BT module and the first antenna so that the first antenna can transmit and receive BT signals.

[0086] In addition, the second Wi-Fi 2.4G module and the SLE module are connected to the second antenna via a second switch. Specifically, when the second Wi-Fi 2.4G module uses the second antenna, the electronic device controls the second switch to connect the second Wi-Fi 2.4G module and the second antenna so that the second antenna can transmit and receive Wi-Fi 2.4G signals. When the SLE module uses the second antenna, the electronic device controls the second switch to connect the SLE module and the second antenna so that the second antenna can transmit and receive SLE signals.

[0087] Based on the electronic device structure shown in FIG5 , the tablet computer can simultaneously use multiple different communication link time-division multiplexing antennas for communication.

[0088] In one example, as shown in Figure 6, a tablet computer is connected to a router via a Wi-Fi 2.4G link and to a stylus via an SLE link. This Wi-Fi 2.4G link is a MIMO link, consisting of a first sub-link established by a first Wi-Fi 2.4G module with the router via a first antenna, and a second sub-link established by a second Wi-Fi 2.4G module with the router via a second antenna. As can be seen, when the Wi-Fi 2.4G link and the SLE link are operating simultaneously, the second antenna is time-division multiplexed.

[0089] The stylus in the SLE link enters a dormant state when it's stationary or charging. In dormant mode, the stylus and tablet only need to maintain a basic communication connection; the stylus doesn't need to frequently report pressure data to the tablet. Therefore, the communication frequency between the tablet and stylus on the SLE link is relatively low. For example, the tablet and stylus communicate at a frequency of 2.67Hz, meaning they communicate every 375ms to ensure the SLE link remains connected. It's understandable that when the stylus is dormant, the SLE link occupies less space on the second antenna, and the SLE link doesn't affect communication on the second sub-link of the Wi-Fi 2.4G link.

[0090] However, the stylus will enter the working state during the movement. In the working state, the stylus needs to continuously report pressure data to the tablet computer so that the tablet computer can display the thickness of the handwriting based on the pressure data. For example, in order to ensure that the thickness of the handwriting displayed on the tablet computer changes smoothly and does not lose the writing details of the user's pen rising and falling, the stylus reports pressure data to the tablet computer at a communication frequency of 360Hz in the working state, that is, the stylus reports pressure data to the tablet computer once every 2.78ms. It can be understood that when the communication frequency of the SLE link is high, the SLE link will frequently occupy the second antenna, and then frequently interrupt the second Wi-Fi 2.4G module to use the second antenna to send and receive data, thereby seriously affecting the data transmission of the second sub-link in the Wi-Fi 2.4G link, resulting in abnormal data transmission of the Wi-Fi 2.4G link.

[0091] It should be noted that, in this embodiment, the communication frequency of the stylus reporting pressure data to the tablet computer can also be referred to as the reporting rate. It can be understood that the higher the reporting rate of the stylus for pressure data, the smoother the changes in the thickness of the handwriting displayed on the tablet computer; conversely, the lower the frequency of the stylus for pressure data, the more abrupt the changes in the thickness of the handwriting displayed on the tablet computer. For example, as shown in Figure 7, compared to a reporting rate of 66Hz, when the reporting rate is 360Hz, the tablet computer displays smoother changes in the thickness of the handwriting based on the pressure data, and can better reflect the user's writing details.

[0092] In another example, as shown in Figure 8, a tablet computer is connected to a router via a Wi-Fi 2.4G link and simultaneously connected to a Bluetooth headset via a BT link. The Wi-Fi 2.4G link is a SISO link, a communication link established between the tablet computer's first Wi-Fi 2.4G module and the router via a first antenna. The BT link is a communication link established between the tablet computer's BT module and the Bluetooth headset via a first antenna. It can be seen that when the Wi-Fi 2.4G link and the BT link are communicating simultaneously, time division multiplexing the first antenna.

[0093] When the above-mentioned Wi-Fi 2.4G link and BT link communicate simultaneously, if the connection parameters of the BT link are small, such as a small communication frequency, a small audio transmission bit rate, or a small duty cycle during data transmission, the BT link occupies a small portion of the first antenna. In this case, the BT link usually does not affect the communication of the Wi-Fi 2.4G link. However, when the connection parameters of the BT link are large, such as a large communication frequency, a large audio transmission bit rate, or a large duty cycle during data transmission, the BT link occupies a large portion of the first antenna, resulting in a significant reduction in the time the Wi-Fi 2.4G link uses the first antenna, seriously affecting the communication quality of the Wi-Fi 2.4G link, and even leading to the serious consequence of Wi-Fi being unable to access the Internet.

[0094] In summary, when different communication links are communicating simultaneously, due to time division multiplexing of the antennas, the electronic device may not be able to take into account the communication quality of multiple communication links, thereby affecting the user experience.

[0095] To this end, an embodiment of the present application provides a communication link management method, which can adjust one of the communication links when an electronic device uses multiple different types of communication links to communicate and these communication links time-division multiplex the same antenna, thereby taking into account the communication quality of the multiple communication links.

[0096] The method provided in the embodiment of the present application is described below by taking an example in which a first electronic device is connected to a second electronic device through a first communication link and is connected to a third electronic device through a second communication link.

[0097] Figure 9 is a schematic flow chart of a communication link management method provided in an embodiment of the present application. The method includes the following steps S901 to S902.

[0098] S901: A first electronic device communicates simultaneously using a first communication link and a second communication link, wherein the first communication link and the second communication link have time-division multiplexing antennas, and the first communication link and the second communication link use different communication protocols.

[0099] For example, the first communication link is a Wi-Fi 2.4G link, and the second communication link is an SLE link. Alternatively, the first communication link is a Wi-Fi 2.4G link, and the second communication link is a BT link. In addition, the number of antennas time-division multiplexing the first communication link and the second communication link can be one or more, and this embodiment does not limit this.

[0100] S902: The first electronic device manages the first communication link according to the connection parameters of the second communication link, so that the managed first communication link and the second communication link do not have time division multiplexing antennas.

[0101] In this embodiment, the connection parameters of the communication link include, but are not limited to, at least one of the following parameters: communication frequency, code rate, and communication duty cycle.

[0102] The communication frequency is used to indicate the number of communications per unit time. For example, a communication frequency of 66 Hz (Hertz) is used to indicate 66 signal transmissions and receptions per second, and the duration of each signal transmission and reception is a preset value, such as 20 ms (milliseconds). The higher the communication frequency of an electronic device, the smaller the interval between two adjacent communications; conversely, the lower the communication frequency of an electronic device, the larger the interval. For example, when the communication frequency of an electronic device is 66 Hz, the interval is ≈ 15.16 ms; when the communication frequency of an electronic device is 360 Hz, the interval is ≈ 2.78 ms.

[0103] Among them, the communication time interval refers to the difference between two adjacent anchor times. Taking the SLE link as an example, as shown in Figure 10, the SLE link uses a timed transmission and reception communication mechanism, that is, the two communicating electronic devices only initiate communication at a fixed anchor time. The time interval between two adjacent anchor times is usually fixed. A communication process includes a signal sending process and a signal receiving process, and a signal receiving process or a signal receiving process occupies one or more time slots. For example, a time slot is 125us. Taking SLE communication as an example, in the signal sending process, the master device (Master) sends a signal to the slave device (Slave); in the signal receiving process, the slave device (Slave) sends a signal to the master device.

[0104] Bitrate, used to indicate the amount of video or audio data transmitted per unit time, is typically expressed in units such as Kbps (kilobits per second) and Mbps (megabits per second). The bitrate is related to video clarity and the compression format. Generally speaking, with the same compression format, the higher the bitrate, the clearer the video.

[0105] The communication duty cycle is used to indicate the ratio between the signal transmission and reception time of each communication and the time interval between two adjacent communications. The larger the duty cycle, the better the communication effect of the communication link.

[0106] Based on the above connection parameters, the first electronic device may manage the first communication link when the connection parameters are greater than a threshold, so that the managed first communication link and the second communication link do not have time-division multiplexing antennas.

[0107] Optionally, in two communication links that time-division multiplex the same antenna, the electronic device can determine the communication link with the lower priority as the communication link to be adjusted based on the priorities of the two communication links. Exemplarily, the priority of a communication link can be determined based on factors such as the number of its sub-links and the services it handles. In some embodiments, the more sub-links there are in a communication link, the higher the flexibility and adjustability of the communication link, and therefore the lower its priority. For example, a SISO link has a higher priority than a MIMO link. Alternatively, when the number of sub-links is the same, the priority of the communication link that handles high-definition audio is higher than that of other communication links.

[0108] Based on this, in S902, when the priority of the first communication link is lower than the priority of the second communication link, the electronic device manages the first communication link according to the connection parameters of the second communication link so that the managed first communication link and the second communication link do not have time-division multiplexing antennas.

[0109] In this embodiment, the electronic device can manage the first communication link in at least two ways. One way is to maintain the communication protocol of the first communication link unchanged and adjust the antenna used by the first communication link so that the first communication link and the second communication link use different antennas, thereby avoiding mutual interference between the first communication link and the second communication link. Another way is to switch the communication protocol of the first communication link so that the first communication link and the second communication link or other communication link use the same antenna in frequency division multiplexing, thereby avoiding mutual interference between the first communication link and the second communication link.

[0110] Method 1: Keep the communication protocol of the first communication link unchanged and adjust the antenna used by the first communication link.

[0111] Example 1: The first communication link is a MIMO link, and the second communication link is a SISO link.

[0112] In this embodiment, the first communication link includes a first sub-link and a second sub-link, wherein the first sub-link communicates via the first antenna, and the second sub-link communicates via the second antenna. The second communication link communicates via the second antenna. The first communication link and the second communication link operate simultaneously, and the second antenna is reused. Based on this, when a connection parameter of the second communication link exceeds a threshold, for example, when the communication frequency exceeds a communication frequency threshold, the first electronic device disconnects the second sub-link in the second communication link. Thereafter, the first communication link communicates solely using the first antenna, and the second communication link communicates solely using the second antenna, without interfering with each other.

[0113] Optionally, when the connection parameter of the second communication link recovers to less than a threshold, for example, when the communication frequency of the second communication link recovers to less than a communication frequency threshold, the second sub-link in the first communication link is restored. Alternatively, after the second communication link is disconnected, the second sub-link in the first communication link is restored to increase the data transmission rate of the first communication link.

[0114] The method provided in this embodiment is described below using an example in which the first electronic device is a tablet computer as shown in FIG5 , the second electronic device is a router, and the third electronic device is a stylus. The Wi-Fi 2.4G link between the tablet computer and the router is the first communication link, and the SLE link between the tablet computer and the stylus is the second communication link.

[0115] As shown in (a) of Figure 11, the tablet computer is connected to the router via a Wi-Fi 2.4G link and to the stylus via an SLE link. The Wi-Fi 2.4G link is a MIMO link, including a first sub-link and a second sub-link. Among them, the first sub-link is a communication link established between the first Wi-Fi 2.4G module and the router through the first antenna, and the second sub-link is a communication link established between the second Wi-Fi 2.4G module and the router through the second antenna. The SLE link is a SISIO link, which is a communication link established between the SLE module and the stylus through the second antenna. It can be seen that the Wi-Fi 2.4G link and the SLE link reuse the second antenna.

[0116] In the above communication scenario, based on the previous description, it can be seen that when the stylus is in the dormant state, the stylus communicates with the tablet computer at a communication frequency of 2.67Hz, so that the two maintain a basic communication connection. At 2.67Hz, the communication time interval between the stylus and the tablet computer is 375ms. When the stylus switches from the dormant state to the working state, it sends pressure data to the tablet computer through the SLE link at a higher communication frequency (such as 360Hz). This process will frequently interrupt the second sub-link's data transmission and reception, thereby seriously affecting the Wi-Fi performance. Therefore, in order to ensure the overall communication quality of the Wi-Fi 2.4G link, when the tablet computer detects that the communication frequency of the SLE link is greater than the communication frequency threshold, the tablet computer controls the disconnection of the second sub-link in the Wi-Fi 2.4G link to ensure the communication quality of Wi-Fi 2.4G.

[0117] As shown in Figure 11(b), after the tablet disconnects the second sub-link of the Wi-Fi 2.4G link, the Wi-Fi 2.4G link uses the first antenna alone to communicate with the router, transforming from a MIMO link to a SISO link. Furthermore, the SLE link uses the second antenna alone to communicate with the stylus. At this point, the Wi-Fi 2.4G link and the SLE link do not affect each other.

[0118] Optionally, when the stylus switches from active mode to sleep mode, it no longer sends pressure data to the tablet via the SLE link. Therefore, the SLE link occupies less of the second antenna. Based on this, the tablet can restore the previously disconnected second sub-link and switch the Wi-Fi 2.4G link from the SISO link back to the MIMO link. Alternatively, after the SLE link is disconnected, the previously disconnected second sub-link can be restored and the Wi-Fi 2.4G link can be switched from the SISO link back to the MIMO link, thereby increasing the data transmission rate between the tablet and the router.

[0119] In this embodiment, the tablet computer dynamically switches the connection mode of the Wi-Fi 2.4G link according to the communication frequency of the stylus in different working states in the SLE link, so as to obtain the best comprehensive communication effect of SLE and Wi-Fi 2.4G, thereby improving the user's comprehensive experience of using the stylus and surfing the Internet using Wi-Fi.

[0120] Example 2: Both the first communication link and the second communication link are SISO links.

[0121] In this embodiment, both the first and second communication links are SISO links and reuse the first antenna. Therefore, when a connection parameter of the second communication link exceeds a threshold, for example, when the bit rate exceeds a bit rate threshold, the electronic device can switch the first communication link from the first antenna to the second antenna for communication. The first and second antennas are both adapted to the communication protocol used by the first communication link, but the first and second antennas are different. Thereafter, the first communication link communicates solely using the second antenna, while the second communication link communicates solely using the first antenna. The two communication links do not affect each other, thereby ensuring the communication quality of each link.

[0122] The method provided in this embodiment is described below using an example in which the first electronic device is a tablet computer as shown in Figure 5, the second electronic device is a router, and the third electronic device is a Bluetooth headset. The Wi-Fi 2.4G link between the tablet computer and the router is the first communication link, and the BT link between the tablet computer and the Bluetooth headset is the second communication link.

[0123] As shown in (a) of Figure 12, the tablet computer is connected to the router via a Wi-Fi 2.4G link and to the Bluetooth headset via a BT link. Both the Wi-Fi 2.4G link and the BT link occupy only the first antenna in the tablet computer. Furthermore, when the Wi-Fi 2.4G link and the BT link are operating simultaneously, they reuse the first antenna.

[0124] In the above communication scenario, when the tablet computer sends high-definition audio to the Bluetooth headset via the BT link, its bit rate is usually relatively high, for example, 990kbps. In order to ensure the transmission effect of high-definition audio, the Bluetooth headset will seize the first antenna. Accordingly, the tablet computer may significantly increase the occupancy ratio of the BT link to the first antenna, for example, increasing the duty cycle of the BT link from 20% to 75%, resulting in a significant compression of the transmit and receive time of the Wi-Fi 2.4G link, thereby affecting the communication of the Wi-Fi 2.4G link, and even leading to the serious consequence that the Wi-Fi 2.4G cannot access the Internet. For this reason, when the tablet computer detects that the bit rate of the audio transmitted by the BT link is greater than or equal to the bit rate threshold, the Wi-Fi 2.4G link is switched to communication through the second antenna.

[0125] As shown in Figure 12 (b), after the tablet switches the Wi-Fi 2.4G link to the second antenna, the Wi-Fi 2.4G link uses the second antenna for communication, while the BT link uses the first antenna for communication. The Wi-Fi 2.4G link and the BT link do not affect each other, allowing for both communication effects to be taken into account simultaneously.

[0126] Optionally, when the bit rate of the audio transmitted by the BT link recovers to less than the bit rate threshold, the Wi-Fi 2.4G link can be switched back to its original state, that is, the Wi-Fi 2.4G link is established using the first Wi-Fi 2.4G module and the first antenna to minimize its impact on other communication links using the second antenna.

[0127] Example 3: Based on Example 2, further adjust the third communication link.

[0128] Based on Example 2, the first electronic device is further connected to the fourth electronic device via a third communication link, and the third communication link communicates using the second antenna according to the first connection parameters. It will be understood that after the first communication link switches to using the second antenna for communication, the first and third communication links time-division multiplex the second antenna. To mitigate the impact of the first communication link on the third communication link, the first electronic device can control the third communication link to communicate using the second connection parameters. The first connection parameters are greater than the second connection parameters.

[0129] Taking the fourth electronic device as a stylus and the third communication link as an example, the SLE link between the tablet computer and the stylus is shown in FIG13 . As shown in FIG13 , the tablet computer includes the Wi-Fi 2.4G link and the BT link as shown in FIG12 (a), and also includes an SLE link established by the SLE module with the stylus through the third antenna. In this scenario, after the tablet computer switches the Wi-Fi 2.4G link to the second antenna, the Wi-Fi 2.4G link and the SLE link reuse the second antenna, and the Wi-Fi 2.4G link and the SLE link may also affect each other. However, since the tablet computer has only one SLE module, it cannot switch the SLE link to other antennas.

[0130] Therefore, in order to reduce the mutual influence between the Wi-Fi 2.4G link and the SLE link, as shown in (a) to (b) in Figure 13, when the stylus is in working state, the tablet computer can appropriately reduce the communication frequency of the stylus sending pressure data to the tablet computer through the SLE link, for example, from the original first communication frequency to the second communication frequency, so as to leave enough time to ensure the basic usage experience of the Wi-Fi 2.4G link, while ensuring that the SLE link basically works normally. Exemplarily, the first communication frequency can be 360Hz, and the second communication frequency can be 66.67Hz. Among them, the interval corresponding to 360Hz is 2.78ms, and the interval corresponding to 66.67Hz is 15ms.

[0131] It should be noted that in SLE communication, electronic devices communicate based on a timed transmission and reception mechanism. Therefore, when the tablet adjusts the communication frequency of the stylus sending pressure data, the stylus needs to negotiate with the tablet to adjust the anchor point of data transmission and reception.

[0132] During SLE communication, electronic devices are divided into management nodes (i.e., Grant nodes, or G nodes for short) and managed nodes (i.e., Terminal nodes, or T nodes for short). A G node can manage at least one T node, and G nodes and T nodes are connected to jointly complete specific communication functions. For example, in an SLE link between a tablet and a stylus, the tablet is usually a G node and the stylus is usually a T node. When adjusting the communication frequency of the SLE link, the G node and T node need to negotiate parameters.

[0133] In some embodiments, the G-node, acting as the manager of the communication link, directly notifies the T-node of connection parameter updates without negotiating with the T-node. These updates may include frequency or interval updates. For example, as shown in Figure 14A , the G-node first directly sends a connection parameter update instruction to the T-node, instructing the T-node to update the connection parameters. Subsequently, the G-node and the T-node negotiate the time at which the signaling takes effect. Finally, the G-node and the T-node update the connection parameters.

[0134] In other embodiments, the G node negotiates with the T node to update connection parameters. For example, as shown in FIG14B , the G node first sends a connection parameter update request to the T node, requesting that the T node update the connection parameters. Next, the T node sends a connection parameter update response to the G node, indicating that the T node agrees to update the connection parameters. Subsequently, the G node sends a connection parameter update indication to the T node, instructing the T node to update the connection parameters. Next, the G node and the T node negotiate the time at which the signaling takes effect. Finally, the G node and the T node update the connection parameters.

[0135] In some other embodiments, the T-node requests the G-node to update connection parameters. For example, as shown in FIG14C , the T-node first sends a connection parameter update request to the G-node, requesting that the G-node update connection parameters. Next, the G-node sends a connection parameter update indication to the T-node, instructing the T-node to update connection parameters. Subsequently, the G-node and the T-node negotiate a signaling validation time. Finally, the G-node and the T-node update the connection parameters.

[0136] Method 2: Adjust the communication protocol of the first communication link so that the first communication link and other communication links use frequency division multiplexing antennas.

[0137] In this embodiment, the first electronic device needs to support the time-division multiplexing antenna and the frequency-division multiplexing antenna of the first communication link in hardware. Taking the first electronic device as an example, as shown in Figure 15, the tablet computer includes a first Wi-Fi 5G module, a first Wi-Fi 2.4G module, a BT module, a second Wi-Fi 5G module, a second Wi-Fi 2.4G module, an SLE module, a first antenna, and a second antenna.

[0138] Among them, the first Wi-Fi 5G module is connected to the first mixer, the first Wi-Fi 2.4G module and the BT module are first connected to the first switch, and then connected to the first mixer through the first switch, and the first mixer is connected to the first antenna. It can be understood that based on the above connection relationship, the tablet computer supports time division multiplexing of the first antenna with the first Wi-Fi 2.4G module and the BT module, and supports frequency division multiplexing of the first antenna with the first Wi-Fi 5G module and the first Wi-Fi 2.4G module or the BT module.

[0139] In addition, the second Wi-Fi 5G module is connected to the second mixer, the second Wi-Fi 2.4G module and the SLE module are first connected to the second switch, and then connected to the second mixer through the second switch, and the second mixer is connected to the second antenna. It can be understood that based on the above connection relationship, the tablet computer supports the second Wi-Fi 2.4G module and the BT module to use the second antenna in time division multiplexing, and supports the second Wi-Fi 5G module and the second Wi-Fi 2.4G module or the SLE module to use the second antenna in frequency division multiplexing.

[0140] The method provided in this application is described below in detail, taking as an example a first electronic device being the tablet computer shown in FIG15 , a second electronic device being a router, a third electronic device being a Bluetooth headset, and a fourth electronic device being a stylus. The communication link between the tablet computer and the router is a first communication link, the communication link between the tablet computer and the Bluetooth headset is a second communication link, and the communication link between the tablet computer and the stylus is a third communication link.

[0141] Example 1: The first communication link and the second communication link frequency-division multiplex the first antenna.

[0142] As shown in (a) of Figure 16, the tablet computer uses a Wi-Fi 2.4G link to connect to the router through the first antenna, uses a BT link to connect to the Bluetooth headset through the first antenna, and uses an SLE link to connect to the stylus through the second antenna. Among them, the Wi-Fi 2.4G link and the BT link time-division multiplex the first antenna. When the BT link transmits high-definition audio, the Wi-Fi 2.4G link will be seriously affected. Since the second antenna has been occupied by the SLE link, the Wi-Fi 2.4G link cannot use the second antenna alone. Therefore, in order to ensure the communication quality of the first communication link between the tablet computer and the router, the tablet computer can switch the communication protocol of the first communication link from the Wi-Fi 2.4G communication protocol to the Wi-Fi 5G communication protocol. In other words, the tablet computer uses the Wi-Fi 5G link to replace the original Wi-Fi 2.4G link.

[0143] As shown in (b) of Figure 16, after the tablet computer uses the Wi-Fi 5G link to replace the original Wi-Fi 2.4G link, the Wi-Fi 5G link and the BT link frequency-division multiplexing the first antenna. The two communication links have basically no impact on each other, and the communication quality of both can be taken into account.

[0144] Example 2: The first communication link and the third communication link frequency-division multiplex the second antenna.

[0145] As shown in (a) of Figure 17, the tablet computer uses a Wi-Fi 2.4G link to connect to the router through the first antenna, uses a BT link to connect to the Bluetooth headset through the first antenna, and uses an SLE link to connect to the stylus through the second antenna. Among them, the Wi-Fi 2.4G link and the BT link time-division multiplex the first antenna. When the BT link transmits high-definition audio, the Wi-Fi 2.4G link will be seriously affected. To this end, the tablet computer can switch the first communication link from the first antenna to the second antenna while switching the first communication link from the Wi-Fi 2.4G communication protocol to the Wi-Fi 5G communication protocol.

[0146] As shown in (b) of Figure 17, after the tablet computer replaces the original Wi-Fi 2.4G link with the Wi-Fi 5G link, the BT link uses the first antenna alone, and the Wi-Fi 5G link and the SLE link frequency-division multiplex the second antenna. The Wi-Fi 5G link and the BT link do not affect each other, and the communication quality of the two can be taken into account.

[0147] In this embodiment, when the first electronic device switches the communication protocol of the first communication link, it may first query the user and then switch after the user agrees. For example, as shown in Figure 18, the tablet computer may first display: a query message, a confirmation control, and a cancel control; the query message is used to ask the user whether to agree to use the Wi-Fi 5G link to replace the original Wi-Fi 2.4G link. In response to the user's operation of the confirmation control, the tablet computer uses the Wi-Fi 5G link to connect to the router and disconnects the original Wi-Fi 2.4G link.

[0148] Based on the same concept, as an implementation of the above method, an embodiment of the present application provides a communication link management device. The device embodiment corresponds to the above method embodiment. For ease of reading, the device embodiment will no longer repeat the details of the above method embodiment one by one, but it should be clear that the device in this embodiment can correspond to and implement all the contents of the above method embodiment.
