Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic flowchart of a bandwidth allocation method according to an embodiment of the present invention, where the present embodiment is applicable to a case where transmission bandwidth allocation of bluetooth data and WIFI data is not reasonable, the method may be executed by a bandwidth allocation apparatus, the apparatus may be implemented in a software and/or hardware manner, and the apparatus may be integrated in any intelligent device with a network communication function. As shown in fig. 1, the bandwidth allocation method may include:
step 101, when the first-class network device and the second-class network device are connected through a bluetooth network and a WIFI network, a first priority corresponding to the first-class network device and a second priority corresponding to the second-class network device are determined.
Bluetooth is a wireless technology standard that enables short-range data exchange between fixed devices, mobile devices, and personal area networks. WIFI is a high-frequency radio signal, and can be used for wirelessly connecting terminal equipment, such as a personal computer, a PAD (PAD application data) and a mobile phone, with each other to realize data transmission and exchange. At present, most of intelligent devices require bluetooth and WIFI to work simultaneously in many scenes, and bluetooth and WIFI are usually set up in a module simultaneously for cost saving, for example, bluetooth and WIFI of most of set top boxes can coexist in the same chip at present. That is to say, the set top box can be connected with different devices respectively through bluetooth network and WIFI network simultaneously and carry out data transmission at the same time quantum.
In this embodiment, the intelligent device may be connected to the first type of network device through a bluetooth network, may be connected to the second type of network device through a WIFI network, and may be connected to the first type of network device and the second type of network device through a bluetooth network and a WIFI network, respectively. The intelligent device can be a mobile phone, a computer, a television set top box and other devices with network communication functions, wherein the mobile phone, the computer, the television set top box and the other devices are integrated with Bluetooth and WIFI at the same time, and the Bluetooth and the WIFI in the intelligent device are integrated on the same module to share one antenna resource. The first type of network device may be a device with network communication function, such as a bluetooth remote controller, a bluetooth mouse, a bluetooth headset, a bluetooth keyboard, a bluetooth speaker, etc., which can be connected to a bluetooth network. The second type of network device may be a device with a network communication function, such as most of smart phones, computers, and the like, capable of connecting to the WIFI network.
In this embodiment, when the smart device is connected to the first type network device and the second type network device through the bluetooth network and the WIFI network, the bluetooth module and the WIFI module of the smart device may be in data communication connection at the same time, and at this time, both bluetooth and WIFI occupy antenna resources. Under the above scenario that the bluetooth network and the WIFI network are respectively connected with the first type of network device and the second type of network device, a first priority corresponding to the first type of network device and a second priority corresponding to the second type of network device may be determined. The first priority may indicate a priority size at which data belonging to the first type of network device connected through the bluetooth network can be transmitted preferentially, and the second priority may indicate a priority size at which data belonging to the second type of network device connected through the WIFI network can be transmitted preferentially. The data of the first type of network equipment connected through the Bluetooth network or the data of the second type of network equipment connected through the WIFI network can be preferentially transmitted by the intelligent equipment according to the first priority and the second priority. For example, if a first priority corresponding to a first type of network device is greater than a second priority corresponding to a second type of network device, data belonging to the first type of network device connected through the bluetooth network may be preferentially transmitted; if the first priority corresponding to the first type of network device is smaller than or equal to the second priority corresponding to the second type of network device, the data of the second type of network device connected through the WIFI network can be transmitted preferentially.
In this embodiment, predetermined transmission bandwidths are allocated to the first type of network device and the second type of network device for data transmission according to the size relationship between the first priority and the second priority. The predetermined transmission bandwidth may be a predetermined transmission bandwidth size and bandwidth ratio that need to be allocated to the first type network device and the second type network device respectively. For example, setting the transmission bandwidth shared by the bluetooth network and the WIFI network to be 100, the first transmission bandwidth may be set to be 70% of the shared transmission bandwidth, and the second transmission bandwidth may be set to be 30%, that is, the first transmission bandwidth is set to be 70 and the second transmission bandwidth is set to be 30. The first transmission bandwidth and the second transmission bandwidth may be regarded as predetermined transmission bandwidths at this time. Similarly, the first transmission bandwidth may be set to 80 and the second transmission bandwidth may be set to 20.
Optionally, if the first priority is greater than the second priority, allocating a predetermined first transmission bandwidth to the first type of network device and allocating a predetermined second transmission bandwidth to the second type of network device, and using the first transmission bandwidth to perform priority transmission on data belonging to the first type of network device connected through the bluetooth network; the bandwidth of the first transmission bandwidth is preset to be larger than the bandwidth of the second transmission bandwidth. If the first priority is less than or equal to the second priority, allocating the predetermined first transmission bandwidth to the second type of network equipment and allocating the predetermined second transmission bandwidth to the first type of network equipment, and preferentially transmitting data to which the second type of network equipment connected through the WIFI network belongs by using the first transmission bandwidth; the bandwidth of the first transmission bandwidth is preset to be larger than the bandwidth of the second transmission bandwidth.
In addition, when the first transmission bandwidth and the second transmission bandwidth in the predetermined transmission bandwidths are set, the first transmission bandwidth and the second transmission bandwidth can be determined according to the size of the transmission bandwidth shared by the bluetooth network and the WIFI network, the bandwidth required to be occupied by the data belonging to the first type of network device connected through the bluetooth network, and the bandwidth required to be occupied by the data belonging to the second type of network device connected through the WIFI network. Illustratively, if the transmission bandwidth shared by the bluetooth network and the WIFI network is 300, the data belonging to the first type of network device connected through the bluetooth network occupies 30% of the shared transmission bandwidth, and at this time, the occupied transmission bandwidth is 90, so that the bluetooth data transmission can be completed quickly and efficiently. When the transmission bandwidths of the first type network device and the second type network device are preset, the set first transmission bandwidth is not necessarily larger than the second transmission bandwidth, at this time, the data belonging to the first type network device connected through the bluetooth network uses a low transmission bandwidth, and the data belonging to the second type network device connected through the WIFI network uses a high transmission bandwidth.
When the first-class network device and the second-class network device are connected through the Bluetooth network and the WIFI network respectively, the data of the first-class network device connected through the Bluetooth network or the data of the second-class network device connected through the WIFI network are determined to be transmitted preferentially through a bandwidth allocation method, and then corresponding transmission bandwidths are allocated to the first-class network device and the second-class network device according to the determination result. The embodiment of the invention solves the problem that in order to ensure the rapid transmission of WIFI data when WIFI and Bluetooth work simultaneously, WIFI may occupy a large number of antenna resources randomly at certain moments to cause slow and pause Bluetooth data transmission, and realizes the distribution of data transmission bandwidth between WIFI and Bluetooth.
Example two
Fig. 2 is a schematic flow chart of a bandwidth allocation method according to a second embodiment of the present invention, where the first embodiment of the present invention specifically optimizes an operation of determining a first priority corresponding to a first type of network device and a second priority corresponding to a second type of network device. As shown in fig. 2, the bandwidth allocation method may include:
In this embodiment, the first type network device may include one or more first network devices, and may be connected to one or more first network devices of the first type network device through a bluetooth network. The first network device is a device with a network communication function, which can be connected with a Bluetooth network, in the first type of network devices. When the network device is connected with the first type of network device and the second type of network device through the Bluetooth network and the WIFI network, the target network device can be determined in the first type of network device according to the preset priority of each first network device in the first type of network device. It can also be said that which first network device in the first type network devices is the target network device can be determined in the first type network devices according to the preset priority of each first network device in the first type network devices. The target network device may be one or more first network devices of the first type, and the priorities of the one or more first network devices are all greater than the priorities of the second type of network devices and the priorities of the remaining first network devices in the first type of network devices.
For example, assume that the first type of network device includes a bluetooth headset, a bluetooth keyboard, and a bluetooth remote controller, and the second type of network device is a computer with WIFI. If the priority of the Bluetooth remote controller is higher than the priorities of the Bluetooth earphone, the Bluetooth keyboard and the computer with WIFI, the Bluetooth remote controller is determined as a target network device in the first type of network device; and if the priorities of the Bluetooth keyboard and the Bluetooth remote controller are the same and are both greater than the priorities of the Bluetooth earphone and the computer with WIFI, determining that the Bluetooth remote controller and the Bluetooth keyboard are the target network equipment at the same time in the first type of network equipment.
And determining the priority level of each first network device in the first type network device and the second type network device by sequencing the priority level of each first network device and the second type network device. For example, the first network device and the second network device in the first network device may be sorted according to the priority, with the network device with the higher priority being arranged in front and the network device with the lower priority being arranged behind. Optionally, the priority of the data to be transmitted by each first network device in the first type of network devices connected through the bluetooth network and the priority of the data to be transmitted by the second type of network devices connected through the WIFI network are sorted according to the preset priorities of the bluetooth data and the WIFI data, and the priorities of each first network device and each second type of network device in the first type of network devices are determined according to the priority sorting. Furthermore, the data to be transmitted by the first network device connected through the bluetooth network and the data to be transmitted by the second network device connected through the WIFI network may be ranked according to a preset priority. The preset priority of the Bluetooth data to which each first network device belongs in the first type of network devices and the priority of the data to be transmitted by the second type of network devices connected through the WIFI network can be set by a user, and can also be set by the system according to the importance of the Bluetooth data to which each first network device belongs.
Optionally, the priority of the software upgrade data similar to each of the first network device and the second network device in the first network device may be set by the user, and the priority of other data in each of the first network device and the second network device in the first network device may be set automatically by the system. Illustratively, software of the bluetooth remote controller needs to be upgraded regularly, and can be preset by a user, and the priority of the bluetooth software upgrading data is set to be the highest within a certain time period, so that a software upgrading packet of the bluetooth remote controller is transmitted preferentially. Of course, the priority of other data connected via the bluetooth network may be preset. In setting the priority, the time range in which the priority plays a role, such as which time period is valid and which time period is invalid, is also considered.
In this embodiment, after determining that a certain first network device in the first type network devices is a target network device in the first type network devices according to the preset priority of each first network device in the first type network devices, the transmission state of the currently transmitted data of the target network device may be determined. The currently transmitted data of the target network device may be data that needs to be transmitted when the target network device is connected to the target network device through the bluetooth network.
In this embodiment, the transmission status of the current transmission data may include: a start transmission state, an in-transmission state, and an end transmission state. Optionally, a transmission identifier for identifying a transmission state of the current data is added to the current transmission data, and the transmission identifier can identify which state of a start transmission state, an ongoing transmission state, and an end transmission state the current transmission data is in. When the current transmission data is data which is connected with the target network equipment through the Bluetooth network for transmission, the current transmission data is transmitted by adopting a general Attribute protocol (GATT) of the Bluetooth, and the Bluetooth of the Bluetooth and WIFI module on the intelligent equipment is connected and communicated with the Bluetooth on the target network equipment through the GATT service. Based on the GATT service, a transmission identifier may be defined at the GATT layer of the bluetooth protocol stack to identify a transmission status of currently transmitted data. Optionally, if the current transmission data is larger, the current transmission data may be transmitted in the form of segmented data packets, and a transmission identifier is added to each data packet.
For example, when a transmission start identifier indicating that currently transmitted data is in a transmission start state is defined at the GATT layer of the bluetooth protocol stack, this may be specifically; four variable identifications, 5c, f1, 00 and 00 respectively, are defined in the first segment packet of the currently transmitted data, and are used as transmission identifications indicating that the currently transmitted data is in a transmission start state. In the bluetooth protocol, 5c indicates that the first segmented packet is a GATT packet, f1 indicates that the first segmented packet is a packet to which the destination network device belongs, the first 00 indicates 00 th data in the current data, and the second 00 indicates 00 th data in the previous 00 th data. The GATT data packet is data transmitted through a Bluetooth network; f1 indicates the type of the current transmission data of the transmission, such as when upgrading the software of the Bluetooth remote controller, and f1 indicates the Bluetooth remote controller upgrade data packet. When a transmission ending identifier indicating that the current transmission data is in a transmission ending state is defined in a bluetooth protocol stack GATT layer, the transmission ending identifier may specifically be; two variable identifiers, 5c and 86 respectively, are defined in the last segmented packet of the currently transmitted data, and are used as the transmission identifiers indicating that the currently transmitted data is in the end transmission state. In the bluetooth protocol, 5c indicates that the first segment packet is a GATT packet, and 86 indicates that the segment packet is the last packet of the data to which the destination network device belongs.
On the basis of the foregoing embodiment, optionally, determining the transmission state of the currently transmitted data of the target network device includes:
when a data packet carrying a transmission starting identifier is detected in current transmission data, determining that the transmission state of the current transmission data is a transmission starting state; when a data packet carrying a transmission identifier is detected in current transmission data, determining that the transmission state of the current transmission data is a transmission state; and when detecting a data packet carrying a transmission ending identifier in the current transmission data, determining that the transmission state of the current transmission data is a transmission ending state.
In this embodiment, the target network device may be one or more first network devices of the first type of network device, and the priorities of the one or more first network devices are all greater than the priority of the second type of network device and the priority of the remaining first network devices in the first type of network device. The priority of the data transmitted by the connection of the Bluetooth network and the target network equipment is greater than the priority of the data transmitted by the target network equipment in the first type of network equipment and the priority of the data transmitted by the second type of network equipment.
In this embodiment, on the premise of determining the target network device, the size of the first priority corresponding to the first type of network device is determined according to the transmission state of the current transmission data of the target network device. Optionally, determining a first priority corresponding to the first type of network device according to the transmission state of the current transmission data of the target network device includes: when the transmission state of the current transmission data is in a transmission starting state or a transmission state, setting a first priority corresponding to the first type of network equipment as a high priority; and when the transmission state of the current transmission data is in the transmission ending state, setting the first priority corresponding to the first type of network equipment as the low priority.
And step 204, determining a second priority corresponding to the second type of network equipment according to the first priority corresponding to the first type of network equipment.
In this embodiment, when the first priority corresponding to the first type of network device is set as the high priority, the second priority corresponding to the second type of network device is set as the low priority. When the first priority corresponding to the first type of network equipment is set as the low priority, the second priority corresponding to the second type of network equipment is the high priority.
It should be noted that, when determining the first priority corresponding to the first type of network device, it is necessary to first determine the target network device and the transmission status of the current transmission data of the target network device. The first priority corresponding to the first type of network device can be determined only after the transmission states of the current transmission data of the target network device and the target network device are both determined, and then the second priority corresponding to the second type of network device is determined. If one or more target network devices exist in the first type of network device, the subsequent operation is continued. If the target network device is not determined, that is, any target network device does not exist in the first type of network device, the priority of the data transmitted through the bluetooth network is not high, priority transmission is not needed, sufficient transmission bandwidth does not need to be reallocated for the data required to be transmitted by connecting the first type of network device through the bluetooth network, and only the original transmission bandwidth needs to be maintained continuously.
In this embodiment, if the first priority corresponding to the first type of network device is set as the high priority and the second priority corresponding to the second type of network device is set as the low priority, it indicates that the transmission status of the current transmission data of the target network device is transmission start or transmission in progress, and allocates the predetermined first transmission bandwidth to the first type of network device and allocates the predetermined second transmission bandwidth to the second type of network device. Optionally, when the transmission status of the current transmission data of the target network device is transmission start, allocating a predetermined first transmission bandwidth to the first type of network device and allocating a predetermined second transmission bandwidth to the second type of network device; when the transmission state of the currently transmitted data of the target network device is transmission, the data transmission can be continued by keeping the transmission state of the currently transmitted data of the target network device as the allocation scheme at the beginning of the transmission.
In this embodiment, if the first priority corresponding to the first type of network device is set to be the low priority and the second priority corresponding to the second type of network device is the high priority, it indicates that the transmission status of the current transmission data of the target network device is the end of transmission, and allocates the predetermined first transmission bandwidth to the second type of network device and allocates the predetermined second transmission bandwidth to the first type of network device.
It should be noted that, the first transmission bandwidth is larger than the second transmission bandwidth, and the setting of the first transmission bandwidth and the second transmission bandwidth may refer to the setting method in the first embodiment. If the first type of network device does not have the target network device, no bandwidth allocation operation is performed, and only data transmission is performed according to the original transmission bandwidth.
Optionally, when the first type of network device includes a plurality of first network devices, the transmission bandwidth of each first network device is determined according to the priority of each first network device in the first network devices, and the determined transmission bandwidth of each first network device is allocated to each first network device. Specifically, the set transmission bandwidths may be respectively allocated to a plurality of network devices in the first class of network devices according to a preset ratio.
When the first-class network device and the second-class network device are connected through the Bluetooth network and the WIFI network respectively, a target network device in the first-class network device is determined according to the priority of data of the first-class network device connected through the Bluetooth network and the priority of data of the second-class network device connected through the WIFI network, then a first priority corresponding to the first-class network device and a second priority corresponding to the second-class network device are determined according to the transmission state of current transmission data of the target network device, and finally, the predetermined transmission bandwidth is distributed to the first-class network device and the second-class network device according to the first priority and the second priority. The embodiment of the invention solves the problem that in order to ensure the rapid transmission of WIFI data when WIFI and Bluetooth work simultaneously, WIFI may occupy a large number of antenna resources randomly at certain moments to cause slow and pause Bluetooth data transmission, and realizes the distribution of data transmission bandwidth between WIFI and Bluetooth.
EXAMPLE III
Fig. 3 is a schematic flow chart of a bandwidth allocation method provided in a third embodiment of the present invention, where the third embodiment of the present invention provides a specific bandwidth allocation method based on the first and second embodiments, and the bandwidth allocation method can be applied to a set top box with bluetooth and WIFI modules, and is used to ensure that software upgrade data in the set top box can be correctly and quickly transmitted to a bluetooth remote controller when the set top box upgrades software corresponding to the bluetooth remote controller. As shown in fig. 3, the bandwidth allocation method may include:
At present, most of television set top boxes are provided with WIFI and Bluetooth integrated modules, and a part of the set top boxes are directly operated by pure Bluetooth remote controllers, and infrared operation is not adopted in the remote controllers, so that the Bluetooth remote controllers are more and more important for the television set top boxes. In order to continuously improve the operation experience of a user, the software of the bluetooth remote controller generally supports upgrading, and the upgrading method is as follows: and the television set top box end sends the upgrade packet data of the Bluetooth remote controller to the Bluetooth remote controller through the Bluetooth module, and then the Bluetooth remote controller receives the upgrade packet and completes the upgrade. The whole upgrading process is as follows: reading the electric quantity of a battery at the end of the remote controller; in order to ensure that the upgrading process is completely carried out, the battery capacity of the remote controller end is read by the box end through Bluetooth interaction; reading the software version number of the remote controller; in order to compare the software version number of the remote controller end with the local remote controller software version number of the box end, the box end reads the software version number of the remote controller through Bluetooth interaction; remote controller software transmission, wherein the box end reads local remote controller software, reads fixed bytes each time, and then sends the fixed bytes to the remote controller end through Bluetooth; and after the sending is finished, the remote controller automatically restarts to finish upgrading.
Because WIFI and Bluetooth can work simultaneously, in order to ensure the fast transmission of WIFI data, WIFI can occupy a large number of antenna resources randomly at certain moments to cause slow or suspended transmission of Bluetooth data, the bandwidth allocation method of the embodiment can be applied to the software upgrading method of the Bluetooth remote controller.
It should be noted that if it is determined that there is no target network device in the first type of network device, no subsequent other steps need to be performed, that is, the transmission bandwidths of the bluetooth network and the WIFI network do not need to be allocated, and only the transmission needs to be performed according to the original transmission bandwidth.
In the present embodiment, the transmission state of the currently transmitted data of the target network device includes a start transmission state, an in-progress transmission state, and an end transmission state. Optionally, the transmission state of the currently transmitted data of the target network device is detected in real time according to a preset time period. Illustratively, when the television set-top box upgrades software at the bluetooth remote controller end and sends software upgrading data to the bluetooth remote controller through the bluetooth network, the software upgrading data can be sent to the bluetooth remote controller through a bluetooth protocol stack GATT layer in the bluetooth network, and the software upgrading data is sent to the bluetooth remote controller end in a segmentation manner in the sending process, at this moment, the target network device can be the bluetooth remote controller, and the currently transmitted data can be the bluetooth remote controller software upgrading data. Before the software upgrading data is sent to the Bluetooth remote controller end in a segmented mode, a transmission identifier which is carried in each segmented data packet and represents the transmission state of the Bluetooth remote controller software upgrading data of the Bluetooth remote controller is detected, and then the transmission state of the Bluetooth remote controller software upgrading data of the Bluetooth remote controller is identified according to variable identifiers in the transmission identifiers.
In this embodiment, when the transmission state of the currently transmitted data of the target network device is in the transmission starting state or the transmission currently state, it indicates that the priority of the data connected to the target network device through the bluetooth network for transmission is greater than the priority of the data connected to the first network device other than the target network device in the first class of network devices through the bluetooth network and the priority of the data connected to the second class of network devices through the WIFI network, and the transmission state of the data connected to the target network device through the bluetooth network for transmission is in the transmission starting state or the transmission currently state.
In this embodiment, when the transmission state of the current transmission data of the target network device is in the transmission start state, it indicates that it is detected that the transmission identifier carried in the current transmission data is the transmission start identifier, and it is considered that the transmission of the first segment data packet of the current transmission data of the target network device is started now, and a command for reducing the WIFI priority is sent to the WIFI and bluetooth shared module. Optionally, an indication value is set for the transmission state of the currently transmitted data of the target network device, and when the transmission state of the currently transmitted data is transmission start or transmission in progress, the indication value shows 1, which indicates that the currently transmitted data is transmitted to the current target network device through the bluetooth network. Illustratively, if the transmission identifier of the bluetooth remote controller software upgrading data of the bluetooth remote controller is detected to be a transmission starting identifier or a transmission identifier, it indicates that the first segment upgrading data packet of the bluetooth remote controller is transmitted now, at this time, a command for reducing the WIFI priority is sent to the WIFI bluetooth module in the television set top box, and meanwhile, the indicated value of the bluetooth remote controller software upgrading identifier ota _ flag is set to 1, which indicates that software upgrading is currently performed on the bluetooth remote controller. Optionally, a judgment is added in both the disconnected and closed interfaces of the GATT layer of the bluetooth protocol stack, if the ota _ flag value is 1, that is, it indicates that the bluetooth remote controller is performing software upgrade, a command for recovering the WIFI priority is sent to the WIFI bluetooth module, because the GATT is disconnected or closed, it indicates that upgrade is definitely interrupted, at this time, the WIFI priority of the module is to be recovered, and meanwhile, the ota _ flag value is set to 0, which indicates that the bluetooth remote controller has stopped upgrading; once the remote control goes into the GATT disconnected interface for some reason, such as a battery outage or out of range or connection timeout.
Exemplarily, after the WIFI bluetooth module receives a command from the television set top box for reducing the WIFI priority, the priority of the bluetooth remote controller software upgrade data is improved, and the bluetooth preferentially transmits the bluetooth remote controller software upgrade data, which is embodied as follows: when the Bluetooth remote controller software upgrading data is transmitted, the WIFI throughput can be reduced, but in order not to influence the normal use of the WIFI by a user, the throughput reduction rate is not more than 30%.
In this embodiment, when the transmission state of the currently transmitted data of the target network device is in the transmission end state, it indicates that the priority of the data that is connected with the target network device through the bluetooth network and transmitted is greater than the priority of the data that is connected with the first network device other than the target network device in the first class of network devices through the bluetooth network and the priority of the data that is connected with the second class of network devices through the WIFI network, and the transmission state of the data that is connected with the target network device through the bluetooth network and transmitted is in the transmission end state.
In this embodiment, when the transmission state of the currently transmitted data of the target network device is in the transmission end state, it indicates that it is detected that the transmission identifier carried in the currently transmitted data is the transmission end identifier, and then the currently transmitted data of the currently transmitted target network device is considered to be the last segmented data packet, and a command for recovering the WIFI priority is sent to the WIFI and bluetooth shared module. Optionally, an indication value is set for the transmission state of the current transmission data of the target network device, and when the transmission state of the current transmission data is the transmission end state, the indication value shows 0, which indicates that the current transmission data is not transmitted to the current target network device through the bluetooth network. Illustratively, if the transmission identifier of the software upgrading data of the bluetooth remote controller is detected to be the transmission ending identifier, the last segment upgrading data packet of the bluetooth remote controller is transmitted, at this time, a command for recovering the WIFI priority is sent to the WIFI bluetooth module in the television set top box, and meanwhile, the indicated value of the upgrading identifier ota _ flag is set to 0, which indicates that the software upgrading is not currently performed on the bluetooth remote controller.
Exemplarily, after the WIFI bluetooth module receives a command of recovering the WIFI priority from the television set top box, the priority of the bluetooth remote controller software upgrade data is reduced, the priority of the data transmitted through the connection of the WIFI network and the second type of network device is recovered, and the WIFI network is preferentially transmitted, which is specifically represented as follows: and when the WIFI priority is restored, restoring the WIFI throughput. In addition, when the bluetooth remote controller fails to be upgraded, the set-top box of the television still needs to restore the bluetooth remote controller to the state before upgrading, so as to ensure the normal experience of the user.
When the first-class network device and the second-class network device are connected through the Bluetooth network and the WIFI network respectively, a target network device in the first-class network device is determined according to the priority of data of the first-class network device connected through the Bluetooth network and the priority of data of the second-class network device connected through the WIFI network, then a first priority corresponding to the first-class network device and a second priority corresponding to the second-class network device are determined according to the transmission state of current transmission data of the target network device, and finally, the predetermined transmission bandwidth is distributed to the first-class network device and the second-class network device according to the first priority and the second priority. The embodiment of the invention solves the problem that in order to ensure the rapid transmission of WIFI data when WIFI and Bluetooth work simultaneously, WIFI may occupy a large number of antenna resources randomly at certain moments to cause slow and pause Bluetooth data transmission, and realizes the distribution of data transmission bandwidth between WIFI and Bluetooth.
