Description

Link priority determination method and device

Technical Field

The present invention relates to the field of computer technologies, and in particular, to a method and an apparatus for determining a link priority.

Background

Data can be transmitted between terminal devices through a designated link, for example, an Audio data packet can be transmitted between a smart phone and a bluetooth headset connected through bluetooth through an Advanced Audio Distribution Profile (A2 DP) link. At present, in order to ensure that music is smooth and not blocked, a sending end (a smart phone) can improve the priority of an A2DP link after judging that an audio data packet needs to be sent in the A2DP link, and reduce the priority of the A2DP link after the A2DP data packet is sent out. However, the receiving end (bluetooth headset) cannot pre-determine whether the received A2DP packet or an Access Control List (ACL) packet is received in advance, so the A2DP link of the receiving end is usually maintained in the state of the highest priority until the A2DP link is disconnected. The priority of the A2DP link at the receiving end is always higher than that of other links, which affects the utilization rate of the baseband and even causes disconnection of other links.

Detailed Description

For better understanding of the technical solutions in the present specification, the following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings.

It should be understood that the described embodiments are only a few embodiments of the present specification, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present specification without any creative effort belong to the protection scope of the present specification.

The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the specification. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

In the current bluetooth transmission, a receiving end cannot pre-determine whether an A2DP data packet or a common ACL data packet is received in advance, so that an A2DP link of the receiving end is usually kept in a state of the highest priority, the use of other links is affected, and the utilization rate of a baseband is reduced. Based on the above situation, the embodiments of the present invention provide a link priority determining method for setting a designated link to the highest priority in some specific time periods.

Fig. 1 is a flowchart of a link priority determining method according to an embodiment of the present invention. The method may be applied to a terminal device, especially a terminal device serving as a data receiving end, such as a bluetooth headset, a smart speaker, and the like, as shown in fig. 1, and the method may include:

step 101, when the designated data packet is received for the first time in the mth listening period, determining the time of receiving the designated data packet for the first time as the initial time.

Step 102, determining an M +1 th listening period based on the initial time, wherein a listening starting point of the M +1 th listening period is located after the initial time and is away from the initial time by a first threshold.

In the embodiment of the invention, the terminal equipment sets a certain data packet as the specified data packet in advance, and the operation is carried out after the specified data packet is received. If two terminal devices establish a bluetooth connection, the designated data packet according to the embodiment of the present invention may be an A2DP data packet. After receiving the designated data packet, the terminal device determines a monitoring period according to the designated data packet, specifically, the time when the designated data packet is received for the first time according to the monitoring period is determined as an initial time, and then determines a next monitoring period according to the initial time, that is, a monitoring starting point and a monitoring ending point of the next monitoring period are determined.

And 103, setting the designated link corresponding to the designated data packet as the highest priority when the M and M +1 monitoring periods exist.

In the embodiment of the invention, after receiving the specified data packet, the terminal equipment determines the monitoring time period, and sets the specified link corresponding to the specified data packet as the highest priority in any monitoring time period, so that the normal transmission of the specified data packet can be ensured. In the time period except the monitoring time period, the designated link corresponding to the designated data packet is set to be in the non-highest priority, so that the influence on the normal communication of other links is avoided, and the link scheduling process is optimized.

In one embodiment, when the value of M is 1, the monitoring starting point of the M-th monitoring period is the time when the designated data packet is received for the first time; and when the value of M is an integer larger than 1, the monitoring starting point of the M monitoring period is determined according to the moment when the M-1 monitoring period receives the specified data packet for the first time and is away from the corresponding moment by a first threshold value. It can be understood that the terminal device can determine the monitoring starting point of the next monitoring period according to the time (initial time) of first receiving the specified data packet in the current monitoring period, and the 1 st monitoring period is used as the first monitoring period, and the monitoring starting point of the first monitoring period cannot be determined according to the time of receiving the first specified data packet in the previous monitoring period. For the 1 st listening period, the terminal device determines the first time of receiving the specified data packet in the 1 st listening period as the listening starting point of the 1 st listening period.

In an actual scene, when the terminal device just establishes connection with other devices, the default is to set the designated link as a non-highest priority, and whether the designated data packet is received or not is detected in real time. When receiving the specified data packet, the terminal device determines the time when the first specified data packet is received as an initial time, the monitoring starting point of the 1 st monitoring period is the initial time, and the monitoring starting point of the 2 nd monitoring period is after the initial time and is away from the initial time by a first threshold value. In the 1 st listening period and the 2 nd listening period, the terminal device sets the designated link to the highest priority. When the time flow reaches the 2 nd monitoring period, the terminal device still detects in real time, if the specified data packet is received, the terminal device will re-determine the time when the specified data packet is received for the first time in the 2 nd monitoring period as the initial time, and determine the monitoring starting point of the 3 rd monitoring period according to the initial time, and the monitoring starting point of the 3 rd monitoring period is still located after the initial time and is away from the initial time by the first threshold value. If the terminal equipment does not receive the specified data packet in the 2 nd monitoring period, the terminal equipment does not determine the 3 rd monitoring period, the process is ended until the terminal equipment receives the specified data packet again, the 1 st monitoring period is determined again, and the next process is started.

In one embodiment, when the terminal device determines any one of the listening periods, the listening period is divided into a primary listening period and a secondary listening period, where a duration included between a listening start point and a listening end point of the primary listening period is a first value, and a duration included between the listening start point and the listening end point of the secondary listening period is a second value. The first value and the second value may be the same or different values, and may be changed according to actual conditions. The main monitoring period is before the auxiliary monitoring period, and the monitoring end point of the main monitoring period is the monitoring starting point of the auxiliary monitoring period. If the terminal equipment receives the specified data packet in the auxiliary monitoring period, the monitoring end point of the auxiliary monitoring period is prolonged after the specified data packet is received each time. Specifically, the time when the designated data packet is received is taken as a reference point, the monitoring end point of the secondary monitoring period is re-determined, and the updated monitoring end point of the secondary monitoring period is located behind the reference point and has a second value different from the reference point. For example, if the terminal device receives a specific packet at time 8, the listening terminal in the sub listening period is updated with the time as a reference point, where the time covered by a certain listening period is 0 to 10 (omitting units), where the main listening period is 0 to 6 and the sub listening period is 6 to 10. Here, the second value is 4, and the listening end point of the sub listening period is updated to be located at time 12. If the designated packet is not received again between 8 and 12, the listening period ends after time 12.

In the embodiment of the invention, the time period in which the specified data packet is possibly received can be more flexibly covered by setting the main monitoring time period and the auxiliary monitoring time period.

The link priority determination method provided by the embodiment of the present invention is further described in the following with specific embodiments. After the smart phone and the Bluetooth headset are connected through Bluetooth, the smart phone can send an A2DP data packet to the Bluetooth headset through the Bluetooth. The Bluetooth headset is used as a data receiving end, and the time when the smart phone sends an A2DP data packet cannot be determined in advance, namely the starting time is uncertain; it cannot be determined in advance when the smartphone stops sending the A2DP data packet, i.e., the end time is uncertain. Based on the above characteristics, the bluetooth headset may use the link priority determination method of the embodiment of the present invention to set the A2DP link to the highest priority within a specified time period, so that the A2DP packet is not missed, and the utilization rate of the entire baseband is not affected. The bluetooth headset can be regarded as the beginning of the process when receiving the first A2DP data packet until not receiving an A2DP data packet within a certain monitoring period, and the process is ended. In order to make the description clearer, it is considered that the terminal device enters the monitoring mode when receiving the A2DP data packet, and enters the normal mode when the process is finished, as shown in fig. 2, after the bluetooth headset and the smartphone are connected, the bluetooth headset is cyclically switched between the normal mode and the monitoring mode. Taking fig. 3 as an example to further describe the process of switching the bluetooth headset from the normal mode to the listening mode, in fig. 3, one rectangle represents a fixed time duration, a rectangle filled with black color represents the time duration for receiving the A2DP data packet in the listening period, a rectangle filled with a gradually changing dotted line represents the time duration for not receiving the A2DP data packet in the listening period, and a blank rectangle represents the time duration included in the non-listening period. The highest rectangle represents the time length included in the main monitoring period, the 1 st time length (the rectangle with subscript 1) is the time length included in the main monitoring period, the highest-order rectangle is the time length included in the auxiliary monitoring period, the 4 th time length (the rectangle with subscript 4) is the time length included in the auxiliary monitoring period, the lowest rectangle is the time length included in the non-monitoring period, and the 6 th time length (the rectangle with subscript 6) is the time length included in the non-monitoring period. In the embodiment of the invention, the Bluetooth headset sets the first value to be 3, the main monitoring time interval comprises 3 fixed time durations, the second value is set to be 2, and the auxiliary monitoring time interval comprises 2 fixed time durations. The Bluetooth headset receives an A2DP data packet in the 1 st time (the starting point of the 1 st time duration), enters a monitoring mode, sets the 1 st time as an initial time, and simultaneously determines the 1 st monitoring time duration and the 2 nd monitoring time duration, wherein the monitoring starting point of the 1 st monitoring time duration is the 1 st time, the monitoring starting point of the 2 nd monitoring time duration is a first threshold value away from the 1 st time, and the first threshold value is set to be 12 fixed time durations. As can be seen from fig. 3, the bluetooth headset receives the A2DP data packet in the 1 st duration and the 2 nd duration, does not receive the A2DP data packet in the 3 rd to 5 th durations, and does not extend the monitoring endpoint of the auxiliary monitoring period, where the 1 st to 5 th durations are the first monitoring period, and the 6 th to 12 th durations are the non-monitoring period. The bluetooth headset sets the A2DP link to the highest priority level for durations 1 through 5 and sets the A2DP link to a non-highest priority level for durations 6 through 12.

The 2 nd listening period is initially from 13 th to 17 th, from 13 th to 16 th, the bluetooth headset does not receive the A2DP data packet, the A2DP data packet is received for the first time at the 2 nd time (the starting point of the 17 th time), the bluetooth headset determines the 2 nd time as the initial time again, the listening starting point of the 3 rd listening period is determined according to the initial time, and the 3 rd listening period is also 12 fixed times away from the initial time. The 16 th to 17 th time periods are the 2 nd sub-listening time period (the sub-listening time period of the 2 nd listening time period), and the bluetooth headset updates the listening end point of the 2 nd sub-listening time period when receiving the A2DP data packet in the 17 th time period. And receiving the A2DP data packet again within the 18 th time length, updating the monitoring destination again by the Bluetooth headset, wherein the updated monitoring is always separated from the time of receiving the A2DP data packet finally by the 2 nd value (two fixed time lengths in this case), namely the monitoring destination is located within the 20 th time length. After the update, the 2 nd listening period is from 13 th to 20 th periods, the bluetooth headset sets the A2DP link to the highest priority in the 13 th to 20 th periods, and the 21 st to 28 th periods are non-listening periods, in which the bluetooth headset sets the A2DP link to the non-highest priority.

The duration 29 to 33 is the 3 rd listening period, during which the bluetooth headset does not receive the A2DP data packet, the bluetooth headset does not determine the next listening period, and the listening mode exits at duration 33. When receiving the A2DP packet again, the bluetooth headset switches from the normal mode to the listening mode again, and repeats the above process.

The rectangle shown in fig. 3 is only used as an example to describe the link priority determination method of the embodiment of the present invention, and the method is not limited thereto, for example, the rectangle in fig. 3 may also indicate an instant.

Fig. 4 is a schematic diagram of another link priority determining method according to an embodiment of the present invention. As shown in fig. 4, may include:

in step 401, a data packet is received.

After the terminal device establishes Bluetooth connection with other devices, the data packet sent by the opposite terminal can be received.

Step 402, determine whether an A2DP packet is present.

The terminal device determines whether the received data packet is an A2DP data packet, if so, step 403 is performed, otherwise, the detection is continued.

Step 403, entering a listening mode, configuring parameters, and determining the next listening period.

After entering the monitoring mode, the terminal device determines the monitoring starting point of the next monitoring period according to the initial time. The configured parameters may include the first threshold, the first numerical value, the second numerical value, and the determined start point and end point of each snoop, etc.

Step 404, whether an A2DP data packet is received in the current listening period.

If the A2DP packet is received within the current listening period, go to step 405, otherwise go to step 406.

At step 405, the next listening period is determined.

Step 406, the listening mode is exited.

And after the terminal equipment exits the monitoring mode, continuously detecting the data packet, and repeating the process after receiving the A2DP data packet again.

In the embodiment of the invention, the terminal equipment determines a plurality of monitoring periods, and sets the designated link to be the highest priority only in the monitoring periods, thereby not only ensuring that the designated data packet cannot be missed, but also reducing the influence on the scheduling of other links.
