The terminal device in the invention is a sound box or an earphone, but is not limited thereto.
The invention is described below by way of specific embodiments, taking a bluetooth connection as an example:
example one
Referring to fig. 2, the terminal device includes a first terminal device and a second terminal device, the data source device includes a device, the data source device transmits data to the first terminal device, and the first terminal device transfers the data to the second terminal device. At this time, the wireless bandwidth allocation method includes the steps of:
step S21, obtaining a first receiving data rate N13 at which the first terminal device receives the data sent by the data source device, and/or obtaining a first sending data rate N23 at which the first terminal device transfers the received data to the second terminal device.
When data is transmitted by Bluetooth, a link needs to be divided into segments, the number of time slots of each link is obtained by taking the time slots as a unit, the transmission duration of each link can be controlled, and the adjustment of the bandwidth is controlled according to the principle. The amount of data that a slot can transmit in a particular scenario can be calculated or known, and the time for a slot is 625us, so that the number of slots can be calculated from the data rate.
For example, the first terminal device monitors the received data amount (i.e. the data amount sent by the data source device to the first terminal device, data rate N13= (data amount/monitoring time), while the first terminal device monitors the data amount forwarded to the second terminal device, data rate N23= (data amount/monitoring time), and the first terminal device calculates the number of link bandwidth slots of the link formed by the data source device and the first terminal device and the number of link bandwidth slots of the link formed by the first terminal device and the second terminal device by combining N13 and N23.
Step S22, determining the number of link bandwidth time slots that each link needs to adjust according to the first receiving data rate N13 and/or the first sending data rate N23.
In this step, specifically, the first terminal device calculates, by combining with the first receiving data rate N13, the number of link bandwidth slots of a link formed between the data source device and the first terminal device, and the first terminal device calculates, by combining with the first sending data rate N23, the number of link bandwidth slots of a link formed between the first terminal device and the second terminal device. And determining the number of the link bandwidth time slots which need to be adjusted of each link by comparing and calculating the number of the link bandwidth time slots of the two links.
In this embodiment, the number of link bandwidth slots that each link needs to adjust is calculated and determined according to the difference between the first receiving data rate N13 and the first sending data rate N23, specifically:
if N13> N23, calculating the number V2 of link bandwidth time slots needing to be increased of a link formed between the first terminal equipment and the second terminal equipment according to the difference value of N13-N23; adjusting bandwidth allocation according to V2;
if N13< N23, calculating the number V1 of link bandwidth time slots needing to be increased of a link formed between the data source equipment and the first terminal equipment according to the difference value between N23 and N13; bandwidth allocation is adjusted according to V1.
And step S23, carrying out bandwidth allocation according to the link bandwidth time slot number needing to be adjusted.
Since the total number of timeslots is fixed, as the number of timeslots of one link increases, the number of timeslots corresponding to another link decreases. According to the principle, the number of the bandwidth time slots of the links needing to be adjusted can be calculated according to the data rate of each link, and dynamic bandwidth adjustment is realized according to the number of the bandwidth time slots of the links needing to be adjusted, so that automatic adaptation to each scene is realized, the bandwidth utilization rate is improved, and the service quality requirements under each scene and each communication state are ensured.
Please refer to fig. 3, which is a schematic diagram illustrating a multi-link bandwidth allocation method according to the present invention. Each link is composed of one working segment when in a data transmission state. The time of each working segment is a fixed value, and the bandwidth is evenly distributed as shown in (3 a) of fig. 3: under the default condition, the adjustment thresholds adjust _ val of the link1 and the link2 are both 0, when the link1 completes one working segment, whether the link2 needs to work is searched, the link2 is switched to, and the link2 also searches and switches back to the link1 after completing one working segment, and the steps are repeated.
The operation effect after bandwidth allocation according to the present invention is shown in (3 b) of fig. 3: the adjustment threshold adjust _ val of the link1 is adjusted to 1, and the adjustment threshold adjust _ val of the link2 is adjusted to 2. In actual work, after the link1 continuously completes two working segments, the link2 is searched and switched, and then the link2 is searched and switched back to the link1 after continuously completing three working segments, and the process is repeated in this way.

The terminal equipment comprises one piece of equipment, the data source equipment comprises first data source equipment and second data source equipment, and the terminal equipment is in Bluetooth connection with the first data source equipment and the second data source equipment respectively. The scenario is an adaptive emphasis point, that is, when a first data source is far away from a terminal device, bandwidth is allocated to a second data source device connected to the terminal device, so that the second data source device is emphasized.
As shown in fig. 4, the wireless bandwidth allocation method includes the following steps:
step S41, obtaining a first receiving data rate N33 at which the terminal device receives the data sent by the first data source device, and/or obtaining a second receiving data rate N43 at which the terminal device receives the data sent by the second data source device.
And step S42, determining the number of link bandwidth time slots which need to be adjusted by each link according to the first receiving data rate N33 and/or the second receiving data rate N43. In this step, specifically:
under the condition that the number of the bandwidth timeslots of the first data source device and the terminal device is greater than the number of the bandwidth timeslots of the second data source device and the terminal device, when the duration that N33 is less than the set data rate threshold N exceeds the set time threshold T, the number of the bandwidth timeslots of the second data source device and the terminal device is increased, for example, the number of the bandwidth timeslots between the second data source device and the terminal device is increased according to a fixed value, or the number of the bandwidth timeslots to be adjusted of each link is calculated according to N33 and N43, and the like, but not limited thereto. The data rate threshold N and the time threshold T are set artificially, for example, according to experience or requirement under a specific scene.
And S43, adjusting the number of the link bandwidth time slots according to the requirement and performing bandwidth allocation. The step allocation method is the same as the first embodiment, and is not described herein again.

The "emphasis" in the present embodiment is determined by product form or rule requirements, for example: the Bluetooth pushes a song scene, the first data source device plays the song first, the link between the first data source device and the terminal device is the emphasis, and similarly, if the first data source device pauses the song playing and the second data source device plays the song, the emphasis is switched to the link between the second data source device and the terminal device. In the scenario of this embodiment, bandwidth allocation compensation is implemented without affecting the basic information synchronization of the other link, and, of course, the other link cannot be disconnected.
Referring to fig. 5, at this time, the wireless bandwidth allocation method includes the following steps:
step S51, obtaining a first receiving data rate N53 at which the terminal device receives the data sent by the first data source device.
In this step, preferably, a second receiving data rate N63 at which the terminal device receives data sent by the second data source device is obtained at the same time, and it is detected whether the second receiving data rate N63 is 0. The standard data rate threshold P includes a first threshold P1, a second threshold P2, a third threshold P3, a fourth threshold P4, a fifth threshold P5, and a sixth threshold P6, and of course, the number of the standard data rate thresholds P is not limited, and may be set to be one or two or more, and six are provided in this embodiment. The standard data rate threshold P is the corresponding data rate when the transmission requirement of the link is satisfied.

Embodiment IV
The terminal device comprises a device, the data source device and the terminal device have mass data transmission, and the terminal device has the action of paging other data source devices or broadcasting data to other terminal devices.
Please refer to fig. 6, at this time, the wireless bandwidth allocation method includes the following steps:
step S61, detecting whether the terminal device pages other data source devices or broadcasts data to other terminal devices.
Step S62, obtaining a first receiving data rate N73 at which the terminal device receives data sent by the data source device according to the detection result, and calculating the number of link bandwidth time slots that the link needs to adjust according to the first receiving data rate N73 and a set standard data rate threshold P7 that meets the transmission requirement of the link. In this step, specifically:
if the terminal device is detecting to be paging other data source devices or broadcasting data to other terminal devices, calculating the number of link bandwidth time slots required to be adjusted of a link formed between the data source device and the terminal device through the first receiving data rate N73 and the set standard data rate threshold P7.
If the terminal equipment does not page other data source equipment or broadcast data to other terminal equipment, the number of link bandwidth time slots of a link formed between the data source equipment and the terminal equipment adopts an initial default value.
And S63, performing bandwidth allocation according to the link bandwidth time slot number required to be adjusted. The step allocation method is the same as the first embodiment, and is not described herein again.
That is to say, in this embodiment, it is detected that the terminal device is paging other data source devices or broadcasting data to other terminal devices, bandwidth adjustment is performed, otherwise, bandwidth is not adjusted, that is, the default initial value is obtained. Because the wireless transmission is time division multiplexing, the link carries out data transmission when the time period occupied by the link is up. If there is a page or broadcast, the page or broadcast will also occupy a certain period of time, i.e. the data rate of the link is sufficient to meet the current situation, even if there is a page or broadcast, a default value can be used. If the data rate of the link cannot meet the current condition, calculating how many time slots need to be increased to meet the condition, and at the moment, the bandwidth allocation of the link is weighted according to the requirement. Since the speed of the other devices connected thereto is affected when the number of paging slots is small, the respective bandwidths of the link, paging or broadcast are dynamically adjusted to meet the data rate requirements.
