Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a communication processing method, apparatus, device, storage medium, and chip. Background Technology

[0002] Bluetooth, as a short-range wireless connectivity technology, enables convenient, flexible, low-cost, and low-power data communication between devices, making Bluetooth devices widely used in production and daily life.

[0003] Currently, in Bluetooth Low Energy (BLE) master-slave devices, when exchanging data, the slave device typically requests a connection interval, which is determined by the slave device's host. However, in practice, it has been found that the master and slave devices switch connection intervals based on the amount of data exchanged within a certain time period. Furthermore, the host's requirement for data transmission is to complete the data transmission within the shortest possible time interval, or within an agreed-upon time interval. This inability to accurately and promptly predict the specific connection interval leads to untimely or frequent switching, resulting in unsatisfactory switching performance and impacting data transmission efficiency.

[0018] In some embodiments, when the master device needs to send a data packet to the slave device, the target communication parameter is determined by the master device's communication controller based on the amount of data to be transmitted by the master device and the master device's transmission reference threshold.

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0042] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are performed with the authorization of the respective device owner.

[0043] In proposing the embodiments of this disclosure, the applicant discovered that in existing BLE devices, when exchanging data, the slave device typically requests a connection interval. The timing of this connection interval request is usually based on the specific usage scenario of the slave device, or when the message source cannot determine the data volume (e.g., Apple Notification Center Service (ANCS) messages sent by the phone), the connection interval is switched based on the amount of data exchanged between the two parties over a certain period. The drawbacks of this approach include untimely or frequent switching, or the connection interval value being suboptimal, leading to unsatisfactory switching results and impacting data transmission efficiency.

[0044] In theory, data transmission requirements reside on the BLE device's host, specifically at the physical layer / lower-layer communication controller. How and when to transmit data should ideally be controlled by the communication controller, which clearly identifies the users and schedulers assigned during communication—that is, the data receiver and the data sender. The host's data transmission requirement is to complete data transmission within the shortest possible time interval. From the user's perspective, the host's fundamental requirement is the shortest possible transmission time, or to complete the transmission of data within an acceptable time interval. Therefore, in the existing BLE transmission logic, the host cannot accurately and timely estimate the specific connection interval (i.e., the optimal value of the connection interval) and the timing of connection interval switching. The control over switching connection intervals can be delegated to the physical layer's communication controller. The host only needs to ensure that, when a BLE connection is established, both parties maintain a certain threshold range for connection intervals. Within this threshold range, the communication controllers of both parties further determine the specific connection interval and update timing.

[0045] Please see Figure 1 This is a schematic diagram of a communication processing flow provided by existing technology. For example... Figure 1As shown, both the master and slave devices include a host and a communication controller. After establishing a frequency-hopping communication link, the slave device sends a data volume threshold (i.e., the aforementioned transmission reference threshold N0) based on its host. Then, it compares the number of data packets transmitted within a preset time interval with the data volume threshold N0. Specifically, for example, it might require sending N data packets continuously within a very short time interval (N>N0); or receiving N data packets within consecutive very short time intervals (N>N0), etc. In this case, the slave device's host sends a request command (REQ) to the slave device's communication controller to request a change in the connection interval. When the slave device's communication controller receives the REQ, it sends the REQ to the master device. The master device's communication controller, upon receiving the REQ, forwards it to the master device's host. The master device's host, upon receiving the REQ, distributes an appropriate connection interval value (RSP) to the master device's communication controller based on its actual transmission capacity. The master device's communication controller, upon receiving the RSP, sends it to the slave device. After receiving the aforementioned connection interval RSP, the communication controller of the slave device forwards it to the slave device's host. This completes a link process for switching connection intervals. However, the specific value of the connection interval RSP and the suggested timing REQ are both initiated by the slave device's host. The drawback of this is that the slave device's host is unaware of the frequency hopping transmission status of the slave device's communication controller. When the master device actively sends data (e.g., a large number of ANCS messages), it is also unaware of the respective data transmission volumes of the master device's host and communication controller. This can lead to untimely or frequent switching, or unsatisfactory switching effects, thus affecting data transmission efficiency.

[0046] To address the aforementioned problems, this disclosure provides a communication processing method, apparatus, device, storage medium, and chip. Please refer to [link to relevant documentation]. Figure 2 This is a schematic diagram illustrating the structure of a communication processing system according to an exemplary embodiment. For example... Figure 2The system shown may include a master device 100 and a slave device 200. The master device 100 includes a host 101 and a communication controller 102, and the slave device 200 also includes a host 201 and a communication controller 202. The master device 100 and the slave device 200 can communicate with each other via a network according to actual needs. As shown, the master-slave device can be divided into two layers: a host layer and a physical layer, on which the host and communication controller are deployed respectively. In practical applications, the master-slave device may include two logic chips, each of which may include the aforementioned host and communication controller components; this disclosure does not impose further limitations or details. The communication controller's RAM buffer can be customized and expanded according to actual needs. Its purpose is to increase the data buffer space distributed by the host layer; for example, it can be set to support the storage of 20 data packets, etc., and this disclosure does not impose further limitations or details.

[0047] The aforementioned host can be the core part of the device, mainly responsible for receiving input signals, performing control operations, and issuing output commands. For example, it can send corresponding request commands to the communication controller, such as requesting to change the connection interval between the master and slave devices. This disclosure will not limit or elaborate on this.

[0048] The aforementioned communication controller can serve as the control system and nerve center of the equipment, responsible for coordinating the work between various components. For example, the communication controller in this disclosure can send corresponding control commands, which carry target communication parameters between the master and slave devices. The functional descriptions of the aforementioned host and communication controller will be detailed below and will not be repeated here.

[0049] Based on the above embodiments, please refer to Figure 3 This is a flowchart illustrating a communication processing method according to an exemplary embodiment. Figure 3 The method shown can be applied to Figure 2 In the system shown, the method may include the following implementation steps: S301, the communication controller 102 of the main device 100 determines the target communication parameters, the target communication parameters including at least the connection interval, the connection interval being determined based on a preset critical threshold.

[0050] In this disclosure, the aforementioned target communication parameters can refer to the parameters used when data communication occurs between the master device 100 and the slave device 200. These parameters may include at least a connection interval, and optionally, a combination of any one or more of the following: update time point (also known as an anchor point), timeout interval, update timing, or other custom parameters. The connection interval can reflect the time interval for data transmission between the master device 100 and the slave device 200. The update time point can indicate the specific / actual time point at which the connection interval is updated. The timeout interval reflects the maximum waiting time for sending and receiving packets after a successful establishment of a physical link between the master device 100 and the slave device 200. If no packets are received from the other device within this timeout interval (i.e., no data interaction occurs within this timeout interval), the established connection will be terminated, and the connection will return to an unconnected state. The update timing specifically indicates the time when the connection interval needs to be updated. The update timing can be an approximate, low-precision time, while the update time point can be a specific, high-precision time. Generally, the precision of the above-mentioned update timing is less than the precision of the above-mentioned update time point, and this disclosure will not impose further limitations or details on this.

[0051] The aforementioned preset threshold can be pre-defined by the system or the user according to actual needs, or it can be set when the master device 100 and the slave device 200 have just established a connection / for the first time. Figure 1 The process shown is based on the upper or lower limit of the threshold range of the connection interval obtained by device 200 through negotiation between host 201 and host 101 of master device 100, which will be detailed below in this disclosure.

[0052] S302, the communication controller 102 of the master device 100 sends a control command to the communication controller 202 of the slave device 200. The control command includes the target communication parameters, which are used to control the data communication between the master device 100 and the slave device 200. Accordingly, the communication controller 202 of the slave device 200 receives the control command.

[0053] Both the master device 100 and the slave device 200 involved in this disclosure can be electronic devices, which can also be referred to as terminal devices, user equipment (UE), mobile stations (MS), mobile terminals (MT), etc. Electronic devices can be automobiles with communication functions, smart cars, mobile phones, wearable devices, tablets, computers with wireless transceiver capabilities, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminal devices in industrial control, wireless terminal devices in self-driving, wireless terminal devices in remote medical surgery, wireless terminal devices in smart grids, wireless terminal devices in transportation safety, wireless terminal devices in smart cities, wireless terminal devices in smart homes, etc. The embodiments of this disclosure do not limit the specific technologies or device forms used in the above-mentioned electronic devices.

[0054] By implementing the embodiments of this disclosure, the communication controller of the master device can determine target communication parameters, which include at least a connection interval determined based on a preset critical threshold. The master device then sends a control command to the communication controller of the slave device. This control command includes the target communication parameters, which are used to control data communication between the master and slave devices. In this way, the master and slave devices actively negotiate / adjust the corresponding target communication parameters through their underlying communication controllers, avoiding the technical problems associated with related technologies that rely on the slave device's host to request connection intervals. These problems include the inability to accurately and timely estimate specific connection intervals, unsatisfactory handover effects, and reduced data transmission efficiency. This improves the convenience and accuracy of communication processing and enhances data transmission efficiency. The following section discusses different application scenarios. Figure 3 The embodiments described below are implemented in detail. Please refer to [link to specific examples]. Figure 4 This is a schematic diagram illustrating a communication processing scenario according to an exemplary embodiment. For example... Figure 4The scenario depicted is that the master device 100 needs to send data packets to the slave device 200. In this case, this disclosure can expand the buffer space (RAM buffer) of the communication controller 102 of the master device 100 according to actual needs. The purpose is to increase the buffer space size of the data (packets) sent by the host 101 of the master device 100 in the communication controller 102, for example, by increasing the number of data packets buffered, such as 20, etc. Based on Figure 4 Please refer to the schematic diagram of the scene shown. Figure 5 This is a flowchart illustrating another communication processing method according to an exemplary embodiment. Figure 5 The method shown may include the following implementation steps: S501, the communication controller 102 of the master device 100 obtains the amount of data to be transmitted by the master device 100 and the transmission reference threshold of the master device 100. The amount of data to be transmitted by the master device 100 is the number of data packets to be sent to the slave device 200 that are cached in the communication controller 102 of the master device 100. The transmission reference threshold of the master device 100 is determined based on the cache size of the communication controller 102 of the master device 100.

[0055] The amount of data to be transmitted (N) in the master device 100 can refer to the number of data packets sent from the host 101 of the master device 100 to the communication controller 102 of the master device 100 within a preset first time period, that is, the number of data packets to be sent to the slave device 200. The preset first time period can be a time period pre-defined by the system or the user according to the actual situation. For example, it can be an empirical value set based on user experience, or a statistical value calculated based on a series of experimental data. Usually, the preset first time period is relatively short, such as 1 second.

[0056] The transmission reference threshold of the aforementioned master device 100 can refer to a reference threshold used to determine the amount of data to be transmitted by the master device 100. It is related to the buffer size of the communication controller 102 of the master device 100; that is, the transmission reference threshold of the master device 100 can be determined based on the buffer size of the communication controller 102. Generally, the transmission reference threshold of the master device 100 and the buffer size of the communication controller 102 are positively correlated. For example, the larger the buffer size of the communication controller 102, the larger the transmission reference threshold of the master device 100; conversely, the smaller the buffer size of the communication controller 102, the smaller the transmission reference threshold of the master device 100. For instance, the transmission reference threshold of the master device 100 can be half or one-third of the buffer size of the communication controller 102, etc. For example, the transmission reference threshold can be 10, etc. This disclosure does not impose further limitations or details in this regard.

[0057] This disclosure does not limit the implementation method for obtaining the amount of data to be transmitted in the master device 100 and the transmission reference threshold of the master device 100. For example, it can be obtained from the communication controller 102, or it can be obtained from other devices or platforms through the network. This disclosure will not go into detail about these aspects.

[0058] S502, the communication controller 102 of the master device 100 determines the target communication parameters based on the amount of data to be transmitted by the master device 100 and the transmission reference threshold of the master device 100. The target communication parameters include at least the connection interval, which is determined based on a preset critical threshold.

[0059] This disclosure does not limit the implementation method for determining the aforementioned target communication parameters. The target communication parameters may at least include a connection interval, and optionally may also include one or more of the following: update time point, timeout interval, update timing, or other custom parameters. For a description of the aforementioned target communication parameters, please refer to the foregoing. Figure 3 The relevant descriptions in the embodiments described above will not be repeated here. An example is provided using the target communication parameters, including the connection interval. This disclosure compares the amount of data to be transmitted by the master device 100 with the transmission reference threshold of the master device 100. In practical applications, there may be one or more transmission reference thresholds, which can be determined according to the actual situation, and this disclosure does not limit this. Two possible implementation methods are described below.

[0060] In one implementation, there is one transmission reference threshold. Specifically, when the amount of data to be transmitted by the master device 100 is greater than the transmission reference threshold of the master device 100, the connection interval can be determined based on a preset first critical threshold T1, that is, the preset critical threshold is the preset first critical threshold T1. Conversely, when the amount of data to be transmitted by the master device 100 is less than or equal to the transmission reference threshold of the master device 100, the connection interval can be determined based on a preset second critical threshold T2, that is, the preset critical threshold is the preset second critical threshold T2. The first critical threshold T1 and the second critical threshold T2 can correspond to the lower and upper critical thresholds of the connection interval obtained when the master device 100 and the slave device 200 first establish communication. Generally, the first critical threshold T1 is less than the second critical threshold T2. That is, the aforementioned first critical threshold T1 can be the lower limit critical threshold of the connection interval obtained when the master device 100 and the slave device 200 establish communication, and the aforementioned second critical threshold T2 can be the upper limit critical threshold of the connection interval obtained when the master device 100 and the slave device 200 first establish communication. It should be noted that when the master device 100 and the slave device 200 have just / first established communication, the threshold is... Figure 1 The process shown allows for negotiation of a connection interval threshold range [T1, T2] between the host devices of the master and slave devices. T2 is greater than T1. The first critical threshold T1 and the second critical threshold T2 can be stored in the communication controller 102 of the master device 100 and the communication controller 202 of the slave device 200, respectively. Optionally, the first critical threshold T1 and the second critical threshold T2 can be uploaded and stored in the host 101 of the master device 100 and the host 201 of the slave device 200, or they can be neither uploaded nor stored in these locations; this disclosure does not limit this.

[0061] In another embodiment, there are two transmission reference thresholds, such as a first reference threshold and a second reference threshold. Specifically, when the amount of data to be transmitted by the master device 100 is greater than the first reference threshold, the connection interval can be determined based on a preset third critical threshold T3, that is, the preset critical threshold is the preset third critical threshold T3. Alternatively, when the amount of data to be transmitted by the master device 100 is less than or equal to the first reference threshold and greater than the second reference threshold, the connection interval can be determined based on a preset fourth critical threshold T4, that is, the preset critical threshold is the preset fourth critical threshold T4. Or, when the amount of data to be transmitted by the master device 100 is less than or equal to the second reference threshold, the connection interval can be determined based on a preset fifth critical threshold T5, that is, the preset critical threshold is the preset fifth critical threshold T5. The aforementioned third critical threshold, fourth critical threshold, and fifth critical threshold can all correspond to the critical threshold of the connection interval obtained when the master device 100 and the slave device 200 first establish communication. They can be determined according to the actual situation, and this disclosure will not impose too many restrictions or details on them.

[0062] In an optional embodiment, the target communication parameters can also be determined based on the communication bandwidth between the master device 100 and the slave device 200 within the connection interval. Specifically, the target communication parameters can be negatively correlated with the communication bandwidth. For example, if the communication bandwidth occupied between the master device 100 and the slave device 200 is larger within the connection interval, the update time of the connection interval is closer to the current system time (i.e., the smaller the update time), and the smaller the connection interval, thus meeting the requirement for timely data transmission. Conversely, if the communication bandwidth occupied between the master device 100 and the slave device 200 is smaller within the connection interval, the update time of the connection interval is further away from the current system time (i.e., the larger the update time), and the larger the connection interval, thus meeting the requirement for timed and quantitative data transmission.

[0063] For example, when the amount of data to be transmitted by the master device 100 is greater than the transmission reference threshold of the master device 100, the preset critical threshold can be a preset first critical threshold T1. If the communication bandwidth between the master device and the slave device is sufficient / large (e.g., greater than the preset first bandwidth value), this disclosure can directly determine T1 as the connection interval. Conversely, if the communication bandwidth between the master device and the slave device is small (e.g., less than the preset second bandwidth value), this disclosure can select a connection interval between the first critical threshold T1 and the second critical threshold T2, for example, setting the connection interval to a value far from T1, but also less than T2. ​​Similarly, when the amount of data to be transmitted by the master device 100 is less than or equal to the transmission reference threshold of the master device 100, the preset critical threshold can be a preset second critical threshold T2. If the communication bandwidth between the master device and the slave device is sufficient / large, this disclosure can directly determine T2 as the connection interval. Conversely, if the communication bandwidth between the master device and the slave device is small, this disclosure may select a value that is far from T2 as the connection interval, etc., and this disclosure will not impose too many restrictions or details on this.

[0064] S503, the communication controller 102 of the master device 100 sends a control command to the communication controller 202 of the slave device 200. The control command includes the target communication parameters, which are used to control the data communication between the master device 100 and the slave device 200. Accordingly, the communication controller 202 of the slave device 200 receives the control command.

[0065] The communication controller 102 of the master device 100 can send the above-mentioned target communication parameters to the communication controller 202 of the slave device 200 through control commands, such as sending and informing the slave device 200 of the connection interval.

[0066] In one optional implementation, the target communication parameters include the connection interval and the update time point. After receiving the control command, the communication controller 202 of the slave device 200 can respond to the control command by updating the connection interval based on the update time point, that is, actually updating the connection interval between the master and slave devices according to the update time point.

[0067] In another optional embodiment, the communication controller 102 of the master device 100 can determine the sending time of the control command as the update timing of the connection interval. This update timing indicates the time when it is desired / needed to update the connection interval. The update timing can be an approximate, less precise time, while the update time point can be a specific, more precise time. Typically, the precision of the update timing is less than the precision of the update time point. For example, the update timing can be the time when the control command is sent, such as 16:00. The update time point can be the actual time when the connection interval is updated; for example, when the communication bandwidth is large, the update time point could be 16:02, etc. This disclosure does not impose further limitations or details on this.

[0068] To help better understand the embodiments of this disclosure, the following is combined with Figure 4 The scenario is illustrated below. Taking the transmission reference threshold of the master device 100 as an example, when the master device 100 and the slave device 200 have just established a communication connection, the slave device 200 and the master device 100 can use... Figure 1The threshold range of the connection interval shown in the process is [T1, T2], where T2 > T1. T1 and T2 are stored in the communication controller 102 of the master device 100 and the communication controller 202 of the slave device 200, respectively, and are not sent to their respective hosts. This disclosure defines a connection interval of [T1, (T1+T2) / 2] as a fast connection and [(T1+T2) / 2, T2] as a slow connection. When a large number of data packets are sent from the master device 100 to the slave device 200, the timing of the connection interval update can be determined by the buffer size of the communication controller 102 of the master device 100. For example, within a very short period of time T, the host 101 of the master device 100 sends N data packets to the communication controller 102 of the master device 100, where N is greater than the transmission reference threshold 10 of the master device 100. At this point, the communication controller 102 of the master device 100 selects a suitable connection interval RSP and a suitable anchor point close to the first critical threshold T1 of the connection interval to actively switch to a fast connection for rapid data transmission. Without waiting for the host 101 of the master device 100 to send a request command REQ, the communication controller 102 of the master device 100 directly sends a control command to the communication controller 202 of the slave device 200. The communication controllers of these two devices actively negotiate the corresponding target communication parameters through the underlying physical link layer, without waiting for either the host 201 of the slave device 200 or the host 101 of the master device 100 to send their respective request commands REQ. The transmission reference threshold 10 is the idle change threshold of the communication controller 102 (ram buffer) of the master device 100, and its change controls the timing of the connection interval update. Generally, the higher the transmission reference threshold (the larger the value), the more urgent the data transmission demand of the upper-layer host; while the lower the transmission reference threshold (the smaller the value), the more time-bound and quantity-based the data transmission demand of the upper-layer host.

[0069] It can be seen that both the master device 100 and the slave device 200 utilize the underlying communication controller to actively negotiate / adjust target communication parameters, avoiding technical problems such as inaccurate or unreasonable connection intervals and update timings of single requests from the upper-layer host of the slave device 200. Simultaneously, during chip design, the hardware cache space (RAM buffer) of the master device 100's communication controller 102 is increased to cache more data packets sent from the host 101 of the master device 100. The connection interval and update timing of both devices are then determined by the transmission reference threshold within the master device 100's communication controller 102. This improves the convenience and accuracy of communication processing and enhances data transmission efficiency. Please see Figure 6 A schematic diagram illustrating another communication processing scenario according to an exemplary embodiment. For example... Figure 6The scenario shown depicts a slave device 200 needing to send data packets to a master device 100. In this case, this disclosure can expand the RAM buffer of the communication controller 202 of the slave device 200 according to actual needs. The purpose is to increase the size of the buffer space in the communication controller 202 for data (packets) sent from the master device 201 of the slave device 200, for example, by increasing the number of data packets buffered, such as 20, etc. Based on Figure 6 Please refer to the schematic diagram of the scene shown. Figure 7 This is a flowchart illustrating another communication processing method according to an exemplary embodiment. Figure 7 The method shown may include the following implementation steps: S701, the communication controller 202 of the slave device 200 sends a request command to the communication controller 102 of the master device 100, the request command being used to request the master device 100 to determine the target communication parameters. Accordingly, the communication controller 102 of the master device 100 receives the above request command.

[0070] The aforementioned request command can be sent from the communication controller 202 of the slave device 200 to the communication controller 102 of the master device 100 according to actual needs. This request command is used to request the master device 100 to determine the target communication parameters between the master and slave devices. For a description of the target communication parameters, please refer to the foregoing. Figure 3 The relevant descriptions in the embodiments will not be repeated here.

[0071] In one implementation, the request command carries / includes the preset critical threshold. Specifically, the communication controller 202 of the slave device 200 can obtain the amount of data to be transmitted from the slave device 200 and the transmission reference threshold of the slave device 200. This disclosure does not limit the implementation method for obtaining the amount of data to be transmitted from the slave device 200 and the transmission reference threshold of the slave device 200, for example, they can be obtained from the communication controller 202, or they can be obtained from other devices or platforms via the network, etc., which will not be described in detail here. Further, the communication controller 202 of the slave device 200 determines the preset critical threshold based on the amount of data to be transmitted from the slave device 200 and the transmission reference threshold of the slave device 200; and sends the preset critical threshold in the request command to the communication controller 102 of the master device 100.

[0072] This disclosure does not limit the implementation method for determining the aforementioned preset critical threshold. Specifically, for example, this disclosure can compare the amount of data to be transmitted by the slave device 200 with the transmission reference threshold of the slave device 200. In practical applications, there may be one or more transmission reference thresholds, which can be determined according to the actual situation, and this disclosure does not limit this. Two possible implementation methods are described below as examples.

[0073] In one implementation, there is one transmission reference threshold. Specifically, when the amount of data to be transmitted by the slave device 200 is greater than the transmission reference threshold of the slave device 200, the preset critical threshold can be a preset first critical threshold T1. Conversely, when the amount of data to be transmitted by the slave device 200 is less than or equal to the transmission reference threshold of the slave device 200, the preset critical threshold can be a preset second critical threshold T2. The first critical threshold T1 and the second critical threshold T2 can correspond to the lower and upper critical thresholds of the connection interval obtained when the master device 100 and the slave device 200 first establish communication. Typically, the first critical threshold T1 is less than the second critical threshold T2. For details regarding the first critical threshold T1 and the second critical threshold T2, please refer to the relevant descriptions in the foregoing embodiments; they will not be repeated here.

[0074] In another embodiment, there are two transmission reference thresholds, for example, the transmission reference thresholds include a first reference threshold and a second reference threshold. Specifically, when the amount of data to be transmitted by the slave device 200 is greater than the first reference threshold of the slave device 200, the connection interval can be determined based on a preset third critical threshold T3, that is, the preset critical threshold is the preset third critical threshold T3. Alternatively, when the amount of data to be transmitted by the slave device 200 is less than or equal to the first reference threshold of the slave device 200 and greater than the second reference threshold of the slave device 200, the connection interval can be determined based on a preset fourth critical threshold T4, that is, the preset critical threshold is the preset fourth critical threshold T4. Alternatively, when the amount of data to be transmitted by the slave device 200 is less than or equal to the second reference threshold of the slave device 200, the connection interval can be determined based on a preset fifth critical threshold T5, that is, the preset critical threshold is the preset fifth critical threshold T5. The aforementioned third critical threshold, fourth critical threshold, and fifth critical threshold can all correspond to the critical threshold of the connection interval obtained when the master device 100 and the slave device 200 first establish communication. They can be determined according to the actual situation, and this disclosure will not impose too many restrictions or details on them.

[0075] The amount of data to be transmitted (N) in the slave device 200 can refer to the number of data packets sent from the host 201 of the slave device 200 to the communication controller 202 of the slave device 200 within a preset second time period, that is, the number of data packets to be sent to the master device 100. The preset second time period can be a time period pre-defined by the system or the user according to the actual situation. For example, it can be an empirical value set based on user experience, or a statistical value calculated based on a series of experimental data. Usually, the preset second time period is relatively short, such as 1 second. The transmission reference threshold of the slave device 200 can refer to a reference threshold used to determine the amount of data to be transmitted in the slave device 200. It is related to the buffer size of the communication controller 202 of the slave device 200, that is, the transmission reference threshold of the slave device 200 can be determined based on the buffer size of the communication controller 202 of the slave device 200. Generally, the transmission reference threshold of the slave device 200 is positively correlated with the buffer size of the communication controller 202 of the slave device 200. For example, the larger the buffer size of the communication controller 202, the larger the transmission reference threshold of the slave device 200; conversely, the smaller the buffer size of the communication controller 202, the smaller the transmission reference threshold of the slave device 200. For instance, the transmission reference threshold of the slave device 200 can be half or one-third of the buffer size of the communication controller 202, etc. For example, the transmission reference threshold can be 10, etc. This disclosure does not impose further limitations or details on this.

[0076] In another embodiment, the aforementioned request command carries at least the amount of data to be transmitted from the slave device 200, and optionally may also include the transmission reference threshold or other custom information of the slave device 200. Specifically, the communication controller 202 of the slave device 200 can obtain the amount of data to be transmitted from the slave device 200, and optionally may also obtain information such as the transmission reference threshold of the slave device 200; this information is carried in the aforementioned request command and sent to the communication controller 102 of the master device 100. This disclosure does not limit the implementation method for obtaining the aforementioned information. Taking the amount of data to be transmitted from the slave device 200 and the transmission reference threshold of the slave device 200 as examples, this disclosure can obtain them from the communication controller 202, or they can be obtained from other devices or platforms via the network, etc., which will not be described in detail here. For a description of the amount of data to be transmitted from the slave device 200 and the transmission reference threshold of the slave device 200, please refer to the relevant description in the previous embodiment, which will not be repeated here.

[0077] S702, the communication controller 102 of the master device 100 responds to the request command and determines the target communication parameters, the target communication parameters including at least the connection interval, the connection interval being determined based on a preset critical threshold.

[0078] This disclosure does not limit the implementation of the above-mentioned target communication parameters. Several possible implementation methods are described below by way of example, but they do not constitute a limitation.

[0079] In one embodiment, the request command includes the preset critical threshold. After receiving the request command, the communication controller 102 of the master device 100 can respond to the request command and determine the corresponding target communication parameters according to the preset critical threshold. For example, it can select a suitable connection interval and update time point close to the preset critical threshold (e.g., the first critical threshold T1 or the second critical threshold T2). This disclosure does not limit or elaborate on this.

[0080] In another embodiment, the aforementioned request command carries at least the amount of data to be transmitted from the slave device 200, and optionally may also include the transmission reference threshold of the slave device 200 or other custom information. Upon receiving the aforementioned request command, the communication controller 102 of the master device 100 can, in response to the request command, determine the aforementioned target communication parameters based on the amount of data to be transmitted from the slave device 200 and the transmission reference threshold of the slave device 200.

[0081] This disclosure does not limit the implementation method for determining the aforementioned target communication parameters. An example is provided using the connection interval as an example. This disclosure compares the amount of data to be transmitted from the slave device 200 with the transmission reference threshold of the slave device 200. When the amount of data to be transmitted from the slave device 200 is greater than the transmission reference threshold, the connection interval can be determined based on a preset first critical threshold T1, i.e., the preset critical threshold is the preset first critical threshold T1. Conversely, when the amount of data to be transmitted from the slave device 200 is less than or equal to the transmission reference threshold, the connection interval can be determined based on a preset second critical threshold T2, i.e., the preset critical threshold is the preset second critical threshold T2. The first critical threshold T1 and the second critical threshold T2 can be referred to the relevant descriptions in the foregoing embodiments, and will not be repeated here.

[0082] In another embodiment, the request command is directly used to request the master device 100 to determine the target communication parameters. After receiving the request command, the communication controller 102 of the master device 100 can respond to the request command and determine the corresponding target communication parameters according to the actual communication needs between the master device 100 and the slave device 200.

[0083] For example, in an optional embodiment, the target communication parameters can be determined based on the communication bandwidth between the master device 100 and the slave device 200 within the connection interval. Specifically, the target communication parameters can be negatively correlated with the communication bandwidth. For instance, if the communication bandwidth occupied between the master device 100 and the slave device 200 is larger within the connection interval, the update time of the connection interval is closer to the current system time (i.e., the smaller the update time), and the smaller the connection interval, to meet the requirement of timely data transmission. Conversely, if the communication bandwidth occupied between the master device 100 and the slave device 200 is smaller within the connection interval, the update time of the connection interval is farther from the current system time (i.e., the larger the update time), and the larger the connection interval, to meet the requirement of timed and quantitative data transmission.

[0084] S703, the communication controller 102 of the master device 100 sends a control command to the communication controller 202 of the slave device 200. The control command includes the target communication parameters, which are used to control the data communication between the master device 100 and the slave device 200. Accordingly, the communication controller 202 of the slave device 200 receives the control command.

[0085] The communication controller 102 of the master device 100 can send the above-mentioned target communication parameters to the communication controller 202 of the slave device 200 through control commands, such as sending and informing the slave device 200 of the connection interval.

[0086] In one optional implementation, the target communication parameters include the connection interval and the update time point. After receiving the control command, the communication controller 202 of the slave device 200 can respond to the control command by updating the connection interval based on the update time point, that is, actually updating the connection interval between the master and slave devices according to the update time point.

[0087] In another optional embodiment, the communication controller 202 of the slave device 200 can determine the sending time of the aforementioned request command as the update timing for the aforementioned connection interval. This update timing is used to indicate the time when it is desired / needed to update the aforementioned connection interval. The aforementioned update timing can be an approximate time with low precision, while the aforementioned update time point can be a specific time with high precision. Generally, the precision of the aforementioned update timing is less than the precision of the aforementioned update time point; this can be referred to in the relevant descriptions in the foregoing embodiments, and will not be repeated here.

[0088] To help better understand the embodiments of this disclosure, the following is combined with Figure 6 The scenario is illustrated below. Taking the transmission reference threshold of slave device 200 as an example, when master device 100 and slave device 200 have just established a communication connection, slave device 200 and master device 100 can use... Figure 1 The threshold range of the connection interval shown in the process is [T1, T2], where T2 > T1. T1 and T2 are stored in the communication controller 102 of the master device 100 and the communication controller 202 of the slave device 200, respectively, and are not sent to their respective hosts. This disclosure defines a connection interval of [T1, (T1+T2) / 2] as a fast connection and [(T1+T2) / 2, T2] as a slow connection. When a large number of data packets are sent from the slave device 200 to the master device 100, the timing of the connection interval update can be determined by the buffer size of the communication controller 202 of the slave device 200. For example, within a very short period of time T, N data packets are sent from the host 201 of the slave device 200 to the communication controller 202 of the slave device 200, where N is greater than the transmission reference threshold 10 of the slave device 200. At this time, the communication controller 202 of the slave device 200 will select the first critical threshold T1 of the connection interval to actively switch to a fast connection for rapid data transmission. This eliminates the need to wait for a request from the host 201 of device 200. The communication controller 202 of device 200 directly sends a request command REQ to the communication controller 102 of master device 100. This request command may include the aforementioned first critical threshold T1. After receiving the request command, the communication controller 102 of master device 100 selects a suitable connection interval and update time point close to T1 and then sends it to the communication controller 202 of device 200. The communication controllers of the two devices actively negotiate the corresponding target communication parameters through the underlying physical link layer, without waiting for the request commands REQ from either the host 201 of device 200 or the host 101 of master device 100. The transmission reference threshold 10 is the idle change threshold of the communication controller 202 (ram buffer) of device 200, and the change of this value controls the timing of updating the connection interval. Generally, the higher the transmission reference threshold (the larger the value), the more urgent the data transmission demand of the upper-layer host; while the lower the transmission reference threshold (the smaller the value), the more timed and quantitative the data transmission demand of the upper-layer host.

[0089] It can be seen that both the master device 100 and the slave device 200 utilize the underlying communication controller to actively negotiate / adjust target communication parameters, avoiding technical problems such as inaccurate or unreasonable connection intervals and update timings of single requests from the upper-layer host of the slave device 200. Simultaneously, during chip design, the hardware cache space (RAM buffer) of the communication controller 202 of the slave device 200 is increased to cache more data packets sent by the host 201 of the slave device 200. The connection interval and update timing of both devices are then determined by the transmission reference threshold within the communication controller 202 of the slave device 200. This improves the convenience and accuracy of communication processing and enhances data transmission efficiency.

[0099] For any content not introduced or described in the embodiments of the present invention, please refer to the relevant descriptions in the foregoing method embodiments; they will not be repeated here.

[0100] Please see also Figure 9 This is a schematic diagram illustrating the structure of another communication processing apparatus according to an exemplary embodiment. For example... Figure 9 The illustrated device can be applied to a communication controller of a slave device, and the device may include a transceiver module 901. Wherein: The transceiver module 901 is configured to receive control commands sent by the communication controller of the master device. The control commands include target communication parameters, which include at least a connection interval. The connection interval is determined based on a preset critical threshold. The target communication parameters are used to control data communication between the master device and the slave device.

[0101] In some embodiments, the target communication parameter further includes an update time point, which indicates the actual time point at which the connection interval is updated, and the apparatus further includes a processing module 902. The processing module 902 is configured to update the connection interval based on the update time point in response to the control command.

[0102] In some embodiments, before the slave device needs to send a data packet to the master device, and before receiving the control command sent by the communication controller of the master device, the transceiver module 901 is further configured to: A request command is sent to the communication controller of the master device, the request command being used to request the master device to determine the target communication parameters.

[0103] In some embodiments, the request command includes the preset threshold, and the processing module 902 is further configured to: The amount of data to be transmitted from the slave device and the transmission reference threshold of the slave device are obtained. The amount of data to be transmitted from the slave device is the number of data packets to be sent to the master device that are cached in the communication controller of the slave device. The transmission reference threshold of the slave device is determined based on the cache size of the communication controller of the slave device. The preset critical threshold is determined based on the amount of data to be transmitted by the slave device and the transmission reference threshold of the slave device.

[0104] In some embodiments, when the master device needs to send a data packet to the slave device, the target communication parameter is determined by the master device's communication controller based on the amount of data to be transmitted by the master device and the master device's transmission reference threshold. The amount of data to be transmitted by the master device is the number of data packets to be sent to the slave device that are cached in the master device's communication controller, and the master device's transmission reference threshold is determined based on the cache size of the master device's communication controller.
