Therefore, in the optional embodiment, the radio frequency resource is arbitrated at the packet receiving and sending time of the bluetooth burst task request, and the high real-time priority of the bluetooth is used for comparison in the comparison of the hardware priority to obtain the final radio frequency resource arbitration result, so that the utilization efficiency of the radio frequency resource can be further improved, and the scheduling effect of the radio frequency can be further improved.

In the embodiment of the present invention, the whole process of radio frequency scheduling in which Wi-Fi and bluetooth coexist is described in detail below, and after a service request triggered by bluetooth is detected, first target information is obtained, where the first target information includes priorities of the Wi-Fi and the bluetooth and/or a service request type of the bluetooth, for example, when the obtained first target information includes the following contents: the method comprises the steps that the service request type of the Bluetooth is an emergency, the software priority value of the Wi-Fi is 4, the software priority value of the Bluetooth is 6, the hardware priority value of the Wi-Fi is 4 and the hardware priority value of the Bluetooth is 6, whether the software priority of the Wi-Fi is smaller than the software priority of the Bluetooth is judged, and the software priority of the Wi-Fi is 4 and the software priority value of the Bluetooth is 6, so that the software priority of the Wi-Fi can be judged to be smaller than the software priority of the Bluetooth; since the service request type of the bluetooth is an emergency, the software priority value of the Wi-Fi is set to 4 at this time, the software priority value of the bluetooth is set to 3, so that the software priority of the Wi-Fi is greater than the software priority of the bluetooth, the use right of the radio frequency resource is allocated to the Wi-Fi on a macro level, at the time of packet receiving and sending of a burst task of the bluetooth, it is determined whether the hardware priority of the Wi-Fi is less than the hardware priority of the bluetooth, since the hardware priority value of the Wi-Fi is 4, the hardware priority value of the bluetooth is 6, it can be determined that the hardware priority of the Wi-Fi is less than the hardware priority of the bluetooth, at this time, the use right of the radio frequency resource is allocated to the bluetooth on a micro level, and finally, the use right of the radio frequency resource is output by hardware arbitration, i.e. the radio frequency resource is allocated to bluetooth.
For example, in another case, when the acquired first target information includes the following: the method comprises the steps that the service request type of the Bluetooth is an emergency, the software priority value of the Wi-Fi is 4, the software priority value of the Bluetooth is 6, the hardware priority value of the Wi-Fi is 4 and the hardware priority value of the Bluetooth is 3, whether the software priority of the Wi-Fi is smaller than the software priority of the Bluetooth is judged, and the software priority of the Wi-Fi is 4 and the software priority value of the Bluetooth is 6, so that the software priority of the Wi-Fi can be judged to be smaller than the software priority of the Bluetooth; since the service request type of the bluetooth is an emergency, the software priority value of the Wi-Fi is set to 4 at the moment, the software priority value of the bluetooth is set to 3, so that the software priority of the Wi-Fi is greater than the software priority of the bluetooth, the use right of the radio frequency resource is allocated to the Wi-Fi on a macro level, at the moment of packet receiving and sending of a burst task of the bluetooth, whether the hardware priority of the Wi-Fi is less than the hardware priority of the bluetooth is judged, since the hardware priority value of the Wi-Fi is 4, the hardware priority value of the bluetooth is 4, the hardware priority of the Wi-Fi can be judged to be equal to the hardware priority of the bluetooth, at the moment, the use right of the radio frequency resource is allocated to the Wi-Fi on a micro level, and finally, the use right of the radio frequency resource is output by hardware arbitration, i.e. the radio frequency resources are allocated to Wi-Fi.
For example, in another case, when the first target information is acquired to include the following: the method comprises the steps that the service request type of the Bluetooth is an emergency, the software priority value of the Wi-Fi is 4, the software priority value of the Bluetooth is 6, the hardware priority value of the Wi-Fi is 4 and the hardware priority value of the Bluetooth is 3, whether the software priority of the Wi-Fi is smaller than the software priority of the Bluetooth is judged, and the software priority of the Wi-Fi is 4 and the software priority value of the Bluetooth is 6, so that the software priority of the Wi-Fi can be judged to be smaller than the software priority of the Bluetooth; since the service request type of the bluetooth is an emergency, the software priority value of the Wi-Fi is set to 4 at the moment, the software priority value of the bluetooth is set to 3, so that the software priority of the Wi-Fi is greater than the software priority of the bluetooth, the use right of the radio frequency resource is allocated to the Wi-Fi on a macro level, at the moment of packet receiving and sending of a burst task of the bluetooth, whether the hardware priority of the Wi-Fi is less than the hardware priority of the bluetooth is judged, since the hardware priority value of the Wi-Fi is 4, the hardware priority value of the bluetooth is 3, the hardware priority of the Wi-Fi can be judged to be greater than the hardware priority of the bluetooth, at the moment, the use right of the radio frequency resource is allocated to the Wi-Fi on a micro level, and finally, the use right of the radio frequency resource is output by hardware arbitration, i.e. the radio frequency resources are allocated to Wi-Fi.
For example, in another case, when the first target information is acquired to include the following: the service request type of the Bluetooth is not an emergency, the software priority value of the Wi-Fi is 4, the software priority value of the Bluetooth is 3, the arbitration result of the radio frequency resource is determined by comparing the software priority value of the Wi-Fi with the software priority value of the Bluetooth, and the final arbitration result of the use right of the radio frequency resource is that the radio frequency resource is used by the Wi-Fi because the software priority value of the Wi-Fi is greater than the software priority value of the Bluetooth.
It can be seen that, by implementing the Wi-Fi and bluetooth coexisting radio frequency scheduling method described in the embodiments of the present invention, the first target information can be obtained after the service request of bluetooth is detected, when the software priority of the Wi-Fi is judged to be smaller than that of the Bluetooth, and when the service request type of the Bluetooth is a burst task, setting the software priority of the Wi-Fi to be greater than that of the Bluetooth, and finally determining the radio frequency resource arbitration result by comparing the hardware priority value of the Wi-Fi with the hardware priority value of the Bluetooth at the packet receiving and sending time of the Bluetooth burst task, and allocates the radio frequency resource to the Wi-Fi or the bluetooth according to the arbitration result, the radio frequency scheduling problem under the coexistence of Wi-Fi and Bluetooth can be processed, the utilization efficiency of radio frequency resources can be improved, and the radio frequency scheduling effect is improved.
