[0030] Based on the scenarios described above regarding the communication control method, various embodiments of the communication control method disclosed in this invention are proposed.

[0031] like Figure 2 As shown, Figure 2 This is a flowchart illustrating one embodiment of the communication control method in this application. The communication control method includes the following steps 201 to 204: 201. In response to a communication control request for a target communication terminal, construct a wireless spectrum map based on the wireless network parameters and associated wireless parameters of the target wireless network corresponding to the communication control request; The communication control method in this embodiment is applied to a communication control device. The type and number of communication control devices are not specifically limited. That is, the communication control device can be one or more target communication terminals that can coexist and communicate and interact via wireless network and Bluetooth. For example, in a specific embodiment, the communication control device can be a smart TV that can play video sources via 2.4GHz WiFi and output audio via Bluetooth-connected speaker devices.

[0033] Optionally, the communication control request is a control request that drives the communication control device to optimize the coexistence of the target wireless network and the target Bluetooth connection coexisting on the target communication terminal. Optionally, this communication control request can be actively triggered by the user by clicking the communication control button on the corresponding communication control page of the communication control device, or it can be automatically triggered by the communication control device when it automatically recognizes the coexistence of the target wireless network and the target Bluetooth connection.

Optionally, these associated wireless parameters can be network parameters such as the basic service set identifier and signal strength of the associated wireless communication networks corresponding to other associated communication devices in the local area network where the target communication terminal is located.

[0037] A wireless spectrum map is a visualized / digital global spectrum situation distribution model formed by the full-domain quantitative collection, statistics, and modeling of the wireless network usage status, interference distribution, signal energy, and channel occupancy of a target communication terminal in its network environment. It is used to characterize the wireless network usage distribution of different devices.

[0038] Optionally, after receiving a communication control request, the communication control device reads the parameters of the target communication network of the target communication terminal to collect the channel status information of the target wireless network in the target communication terminal and obtain the wireless network parameters corresponding to the target wireless network.

That is, the communication control device determines the distribution of the target wireless network's corresponding frequency band status (e.g., congestion, signal strength, and interference) through the wireless network parameters and associated wireless parameters, and models and generates a wireless spectrum map.

[0041] 202. Determine the type of Bluetooth device connected to the target Bluetooth in the target communication terminal based on the wireless spectrum map and coexistence decision strategy; Optionally, after acquiring the wireless spectrum map, the communication control device may also determine the type of Bluetooth device connected to the target Bluetooth in the target communication terminal based on the wireless spectrum map and the coexistence decision strategy.

[0042] Optionally, the coexistence decision strategy is a decision strategy used to determine the Bluetooth device type corresponding to the target Bluetooth connection when the target communication terminal is in a wireless Bluetooth coexistence state. That is, the coexistence decision strategy is a decision strategy used to evaluate whether the target communication terminal is a master device or a slave device. Optionally, the coexistence decision strategy can determine the Bluetooth device type corresponding to the target Bluetooth connection in the target communication terminal through a wireless spectrum map and corresponding information.

[0043] Optionally, the target Bluetooth connection is a Bluetooth connection that coexists with the target wireless network in the target communication terminal.

[0044] Optionally, the Bluetooth device type is a Bluetooth device type that indicates whether the target communication terminal actively controls or passively synchronizes information in the Bluetooth connection. This Bluetooth device type includes a master device type and a slave device type. The master device type indicates that the target communication terminal is a Bluetooth master device type capable of dominating and controlling clearance gaps in the Bluetooth connection. The slave device type indicates that the target communication terminal is a Bluetooth slave device type that passively follows the master device in the Bluetooth connection.

[0045] Optionally, the communication control device determines the map evaluation parameters corresponding to the target communication terminal based on the wireless spectrum map. These map evaluation parameters are network parameters identified based on the wireless spectrum map and to be evaluated. Optionally, these map evaluation parameters include channel awareness parameters, the number of wireless devices covered, and the completeness of the spectrum map. Optionally, in other embodiments, the map evaluation parameters can also be other parameters, such as network layer parameters (indicating whether the target communication terminal is a gateway-level device) and channel control parameters (indicating the device's service weight or load level).

[0046] Optionally, the coexistence decision strategy in the communication control device also pre-sets the weight values ​​corresponding to different map evaluation parameters, which are determined as terminal evaluation weights. The terminal evaluation data of the target communication terminal is calculated based on the map evaluation parameters and the terminal evaluation weights. That is, the communication control device uses the terminal evaluation weights to weight the map evaluation parameters to obtain terminal evaluation data used to quantify whether the terminal is set as the master device.

[0047] Optionally, if the terminal evaluation data is greater than the preset evaluation threshold corresponding to the coexistence decision strategy, then the Bluetooth device type connected to the target Bluetooth in the target communication terminal is determined to be the primary device type. The preset evaluation threshold is a threshold parameter used to determine whether the Bluetooth device type is the primary device type based on the terminal evaluation data.

[0048] Optionally, if the terminal evaluation data is less than a preset evaluation threshold, the Bluetooth device type connected to the target Bluetooth in the target communication terminal is determined to be a slave device type.

[0049] 203. Determine the Bluetooth control command for the target communication terminal based on the Bluetooth device type and the target frequency hopping strategy; Optionally, after determining the Bluetooth device type corresponding to the target communication terminal, the communication control device also determines the Bluetooth control command for the target communication terminal based on the Bluetooth device type and the target frequency hopping strategy.

[0050] Optionally, the target frequency hopping strategy is a control strategy used to determine the clearance or other Bluetooth control parameters corresponding to the target Bluetooth connection in the target communication terminal. This target frequency hopping strategy includes a first frequency hopping strategy and a second frequency hopping strategy. The first frequency hopping strategy is a frequency hopping control strategy that dynamically adjusts the clearance corresponding to the target Bluetooth connection. The second frequency hopping strategy is a control strategy used to adjust the target Bluetooth connection to shorten or increase the interaction interval or improve the Bluetooth transmission strategy.

[0051] Optionally, the Bluetooth control command is a control command to adjust the parameters of the target Bluetooth connection.

[0052] Optionally, if the communication control device determines that the Bluetooth device type is a master device type that can dynamically adjust the clearance, then the target frequency hopping strategy is determined to be the first frequency hopping strategy.

[0053] Optionally, the communication control device determines the frequency hopping clearance for the target Bluetooth connection based on the first frequency hopping strategy and the wireless network bandwidth in the wireless network parameters. That is, the communication control device dynamically adjusts the clearance for the target network connection according to the wireless network bandwidth corresponding to the target wireless network using the first frequency hopping strategy to obtain the frequency hopping clearance. The first frequency hopping strategy includes a first frequency hopping function, which is a function algorithm that reflects the change of the frequency hopping clearance in the same direction as the wireless network bandwidth. That is, the higher the wireless network bandwidth, the larger the corresponding frequency hopping clearance, thereby ensuring that the Bluetooth frequency hopping point can be far away from the primary and secondary channels of the target wireless network, forming a sufficiently large guard band. For example, in a specific embodiment, when the wireless network bandwidth corresponding to the target wireless network is detected to be 40MHz, the communication control device automatically increases the frequency hopping clearance, adjusting the clearance from GAP=3 to GAP=8, and converges the available channels to near the lower limit of the protocol to maximize the guard band. When the wireless network bandwidth corresponding to the target wireless network is detected to be 20MHz, the frequency hopping clearance is decreased according to the first frequency hopping function, releasing more spectrum resources for Bluetooth use and improving spectrum utilization.

[0054] Optionally, the communication control device also collects the Bluetooth channel parameters of the target Bluetooth connection and generates a Bluetooth channel mapping table. That is, the communication control device obtains the channel quality information corresponding to the target Bluetooth connection, gets the Bluetooth channel parameters, generates a Bluetooth channel mapping table representing the optimal channel, and synchronizes the Bluetooth channel mapping table to the peer Bluetooth device in subsequent steps to ensure that both parties can interact under optimal signal conditions.

[0055] Optionally, after obtaining the frequency hopping clearance and the Bluetooth channel mapping table, the communication control device generates a first Bluetooth control command based on the frequency hopping clearance and the Bluetooth channel mapping table.

[0056] Optionally, in other embodiments, when the communication control device determines that the Bluetooth device type is a slave device type, it determines the target frequency hopping strategy as the second frequency hopping strategy.

[0057] Optionally, the communication control device generates Bluetooth boosting instructions based on the second frequency hopping strategy and the target control interface, and summarizes these instructions to obtain a second Bluetooth control instruction. This second Bluetooth control instruction is used to request adjustments to the target Bluetooth connection, such as shortening or increasing the interaction interval or increasing the Bluetooth transmit power. The Bluetooth boosting instruction can be a control instruction used to improve the Bluetooth Quality of Service (QoS) index corresponding to the target Bluetooth connection. Optionally, in one specific embodiment, the communication control device can send a suggestion command through the target control interface to request the control terminal to shorten or increase the interaction interval or increase the transmit power, for synchronization with the peer Bluetooth device to ensure optimal interaction between the two.

[0058] 204. Adjust the target wireless network and / or target Bluetooth connection according to the Bluetooth control command and the communication status parameters corresponding to the target communication terminal to obtain the communication control result.

[0059] Optionally, after receiving the Bluetooth control command, the communication control device adjusts the target wireless network and / or the target Bluetooth connection according to the Bluetooth control command and the communication status parameters corresponding to the target communication terminal to obtain the communication control result.

[0060] Optionally, after receiving the Bluetooth control command, the communication control device adjusts the target Bluetooth connection in the target communication terminal according to the Bluetooth control command, and obtains the communication status parameters corresponding to the adjusted target communication terminal. Based on the communication status parameters, it further adjusts the target wireless network and / or the target Bluetooth connection to obtain the communication control result.

[0061] In one specific embodiment, if the Bluetooth control command of the communication control device is the first Bluetooth control command corresponding to the master device type, then the communication control device adjusts the target Bluetooth connection according to the frequency hopping clearance and Bluetooth channel mapping table in the first Bluetooth control command, and obtains the Bluetooth link index corresponding to the target Bluetooth connection in the communication status parameters. The Bluetooth link index includes any one or more of Bluetooth signal-to-noise ratio, Bluetooth packet error rate, and Bluetooth retransmission rate.

[0062] Optionally, if the communication control device determines that the Bluetooth retransmission rate in the Bluetooth link metrics is greater than a preset retransmission rate threshold, it increases the Bluetooth transmit power of the target Bluetooth connection according to the Link Manager Protocol (LMP) and a power adjustment command to obtain the communication control result. That is, the communication control device sends a first power adjustment command to the peer Bluetooth device via the Link Manager Protocol (LMP) to request the peer Bluetooth device to increase its transmit power, or increases its own transmit power via a second power adjustment command. The power adjustment command is an operation instruction used to increase the Bluetooth transmit power of the peer or itself. The power adjustment command includes a first power adjustment command for adjusting the peer's transmit power and a second power adjustment command for adjusting the local transmit power. Optionally, in a specific embodiment, the first power adjustment command is an LMP_power_control_req PDU command. The second power adjustment command is an HCI_Write_Transmit_Power_Level command.

[0063] Optionally, in one specific embodiment, if the communication control device determines that the Bluetooth control command is the second Bluetooth control command, it sends a request command to the Bluetooth control terminal through the host controller interface, requesting the Bluetooth control terminal to shorten the transmission interval (Min_Interval / Max_Interval), specifying the service type as "guaranteed bandwidth", and suggesting a higher transmit power level to combat time domain and power domain interference by shortening the packet transmission interval and increasing power.

[0064] Optionally, in another specific embodiment, the communication control device further adjusts the Bluetooth connection parameters of the target Bluetooth connection according to the Bluetooth control command to obtain an updated Bluetooth connection.

[0065] Optionally, if the communication control device determines that the Bluetooth communication service corresponding to the updated Bluetooth connection is a target Bluetooth coexistence service, it increases the target retransmission threshold according to the wireless network control policy corresponding to the target wireless network. Here, the target Bluetooth coexistence service is defined as a high-priority Bluetooth communication service. By determining that the Bluetooth communication service is a target Bluetooth coexistence service, the communication control device adjusts the rate adaptively through the wireless network control policy, increasing the target retransmission threshold at the modulation and coding scheme (MCS) level. This avoids a sudden drop in the MCS level or even connection interruption due to transient interference, thereby improving the throughput stability of the target wireless network link.

[0066] Optionally, the communication control device also collects updated wireless parameters of the target wireless network. If the updated wireless parameters do not meet the wireless performance conditions, the target wireless network is adjusted to obtain the communication control result. These updated wireless parameters include stuttering rate and wireless throughput. If the stuttering rate is higher than the stuttering rate threshold or the throughput is lower than the throughput threshold in the wireless performance conditions, it is determined that the wireless network quality corresponding to the target wireless network is poor. The communication control device then further adjusts the frequency hopping clearance corresponding to the target Bluetooth connection or updates the Bluetooth channel mapping table transmitted to the peer Bluetooth device to reduce co-channel interference from the target Bluetooth connection to the target wireless network, thereby improving the multi-wireless collaborative performance and user experience of the terminal in complex wireless network environments.

[0067] In this embodiment, the communication control device responds to a communication control request for a target communication terminal, constructs a wireless spectrum map based on the wireless network parameters and associated wireless parameters of the target wireless network corresponding to the communication control request, determines the Bluetooth device type of the target Bluetooth connection in the target communication terminal based on the wireless spectrum map and a coexistence decision strategy, the Bluetooth device type including master device type and slave device type, determines the Bluetooth control command for the target communication terminal based on the Bluetooth device type and the target frequency hopping strategy, and adjusts the target wireless network and / or the target Bluetooth connection based on the Bluetooth control command and the communication status parameters corresponding to the target communication terminal to obtain a communication control result. This system enables communication terminals to simultaneously utilize wireless networks and Bluetooth connections. It constructs a wireless spectrum map representing the distribution of wireless network usage across different devices in the communication environment using the target wireless network's wireless network parameters and associated wireless parameters. Based on this spectrum map, it determines whether the target Bluetooth connection in the communication terminal is a primary Bluetooth device. Then, based on this Bluetooth device type and the target frequency hopping strategy, it generates a Bluetooth connection strategy for frequency hopping avoidance control. Furthermore, it collects communication status parameters corresponding to the communication terminal for further Bluetooth or wireless network control. This allows for adaptive adjustment of the frequency hopping strategy according to the real-time wireless environment, effectively reducing the risk of co-channel interference, improving the performance of wireless network and Bluetooth coexistence, and optimizing the user communication experience.
