Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 is a schematic flowchart of an access restriction window adjustment method applied to an AP device, provided in one or more embodiments of the present disclosure, and referring to fig. 1, the method may specifically include the following steps:

102, acquiring access information of a workstation accessed to AP equipment; the workstations comprise a first type of workstation, and the first type of workstation transmits and receives data through the access limiting window;

in the wireless network of this embodiment, the wireless network includes an AP device and a workstation accessing the AP device, where the workstation includes a first type of workstation and may further include a second type of workstation; a first type of workstation for transceiving data through an access restriction window, such as a TIM station, a Non-TIM station, etc.; a second type of station, such as an unchelated station, does not need to transmit or receive data through the access restricted window. In order to ensure that each workstation in a wireless network can effectively transmit data, in one or more embodiments of the present description, an AP device acquires access information of the accessed workstations at preset time intervals, because the number of workstations accessed to the AP device may change at any time; as one embodiment, as shown in fig. 2, step 102 comprises:

step 102-2, broadcasting a query message so that a workstation accessed to the AP equipment returns response data when acquiring the query message;

specifically, the AP device broadcasts an inquiry message, such as a Beacon message, at preset time intervals; when each workstation in the wireless network acquires the query message, response data is generated according to the type of the workstation, the identification of the workstation and other information, and the generated response data is sent to the AP equipment. The preset time interval can be set automatically according to the requirement in practical application.

102-4, counting the number of the workstations of the target type according to the type information of the workstations included in the response data; wherein the target type comprises at least a first type;

step 102-6, the number of workstations of the target type is determined as access information.

The AP equipment broadcasts the query message through the preset frequency to acquire the access information of the accessed workstations, and can ensure that the access limiting window parameters of the first type of workstations are adjusted in time when the number of the workstations in the wireless network changes.

Step 104, determining whether to adjust the access limiting window parameters of the first type of workstation or not according to the acquired access information;

in order to reasonably and efficiently adjust the access limiting window of the first type of workstation, in one or more embodiments of the present specification, a corresponding relationship between a number range of the workstations and a wake-up period is preset, where the wake-up period is a total duration for each of the first type of workstations to be woken up once, that is, a total duration of each time slot included in the access limiting window; or presetting the corresponding relation between the number range of the workstations and the grade of the awakening period and the corresponding relation between the grade of the awakening period and the awakening period; to determine an adjusted access restriction window parameter based on the correspondence. Further, in order to determine whether to adjust the access limiting window parameter of the first type of workstation, in one or more embodiments of the present specification, a first number of workstations of the target type obtained last time is further saved, so as to determine a change situation of the number of workstations of the target type according to the first number and the number of workstations of the target type obtained currently, and further determine whether to adjust the access limiting window parameter of the workstations of the first type according to the change situation of the number. Specifically, step 104 includes:

step 104', if the number of the workstations of the target type is different from the stored first number and the number of the workstations of the target type and the first number belong to different preset number ranges, determining to adjust the access limiting window parameter of the workstations of the first type; wherein the first number is the number of workstations of the target type acquired last time.

Specifically, the counted number of the workstations of the target type is compared with the stored first number, if the counted number of the workstations of the target type is consistent with the stored first number, it is determined that the access limiting window parameter of the workstation of the first type is not adjusted, and when the time point corresponding to the preset time interval is reached, step 102 is executed; if not, matching the number of the workstations of the target type with the number range included in the preset corresponding relation to obtain the number range to which the number of the workstations of the target type belongs; matching the first quantity with a quantity range included in a preset corresponding relation to obtain a quantity range to which the first quantity belongs; determining whether the number range to which the number of the target type of workstations belongs is the same as the number range to which the first number belongs, if so, determining not to adjust the access limiting window parameter of the first type of workstations, and executing step 102 when a time point corresponding to a preset time interval is reached; if not, determining to adjust the access restriction window parameters for the first type of workstation.

Therefore, whether the access limiting window parameter of the first type of workstation is adjusted or not is determined by presetting the corresponding relation between different quantity ranges and the awakening period and based on the quantity of the target type of workstations, the stored first quantity and the preset quantity range; therefore, when the number of the workstations is changed slightly and the data transmission of the first type of workstations is not influenced, the adjustment operation of the access limiting window is not required, so that the adjustment times are reduced, and the updating operation of the access limiting window parameters of the first type of workstations is reduced.

Step 106, if yes, determining the adjusted access limiting window parameters of the first type of workstation according to the access information and the preset adjusting rule;

in the embodiment of the present specification, the adjusted access restriction window parameter of the first type of workstation is determined in different manners based on the access information and a preset adjustment rule according to different target types in the access information.

As an embodiment, the access limiting window parameter of the first type of workstation is adjusted according to the number of the first type of workstation; correspondingly, the target type is the first type, and as shown in fig. 3, the foregoing step 102-4 includes:

step 102-4-2, a second number of workstations of the first type is counted according to the type information of the workstations included in the response data.

Specifically, first target response data with the type information being a first type is screened from the received response data, and the number of the first target response data is counted and used as a second number of the workstations of the first type.

Correspondingly, as shown in fig. 3, the foregoing step 102-6 includes:

step 102-6-2, determining a second number of workstations of the first type as access information;

further, as shown in fig. 3, step 106 includes:

step 106-2, if yes, determining a target quantity range to which the second quantity belongs in a plurality of preset quantity ranges;

specifically, if the access limiting window parameter of the first type of workstation is determined to be adjusted, matching the second quantity with a quantity range included in a preset corresponding relationship to obtain a target quantity range to which the second quantity belongs;

step 106-4, determining a target awakening period according to the target quantity range;

specifically, when the preset corresponding relationship includes a first corresponding relationship between a quantity range and a wakeup cycle, a corresponding target wakeup cycle is obtained from the first corresponding relationship according to the target quantity range; and when the preset corresponding relation comprises a second corresponding relation of the quantity range and the awakening period grade and a third corresponding relation of the awakening period grade and the awakening period, acquiring a corresponding target awakening period grade from the second corresponding relation according to the target quantity range, and acquiring a corresponding target awakening period from the third corresponding relation according to the target awakening period grade.

Step 106-6, determining the adjusted access restriction window parameter for the first type of workstation based on the second number and the target wake-up period.

Specifically, the duration of the sub-wake-up period of each workstation of the first type is determined according to the second number and the target wake-up period; determining the starting time of the sub-awakening period of each first type of workstation according to a preset allocation rule and the duration of the sub-awakening period; the duration and start time of the sub-wake-up period are determined as the adjusted access restriction window parameters for the first type of workstation.

Optionally, the durations of the sub-wake-up periods of each of the first type of workstations are the same, correspondingly, the target wake-up period is divided by the second number, and the quotient is determined as the duration of the sub-wake-up period of each of the first type of workstations. It should be noted that the determination manner of the duration of the sub-wake-up period may be set in practical application according to needs, which is not specifically limited in this specification.

Further, the allocation rule may be set by itself in practical application as required, for example, the starting time of the sub-wake-up period of each workstation of the first type is determined in a random allocation manner; or determining the awakening sequence of the workstations of each first type according to the service types of the workstations, and determining the starting time of the sub-awakening period of each workstation of the first type according to the determined awakening sequence; this specification is not particularly limited.

As an example, the correspondence includes a first correspondence of the number range and the wake-up period, which is exemplified as follows:

range of quantities(A)	Wakeup period (millisecond)
		1-5	0.75
6-10	1.50
		11-15	2.35
16-20	3.25

The first number of the saved workstations of the first type is 4, the second number of the counted workstations of the first type is 6, the first number is different from the second number, the number range of the first number is 1-5, the number range of the second number is 6-10, and the access limiting window parameters of the workstations of the first type are determined to be adjusted if the first number and the second number belong to different number ranges; acquiring a target wake-up period of 1.50 milliseconds from the first corresponding relation according to a target number range 6-10 to which the second number belongs, and determining that the sub-wake-up period of each first type of workstation is 1.50/6 to 0.25 milliseconds; for convenience of description, the workstations of the first type are denoted as workstation 1, workstation 2, workstation 3, workstation 4, workstation 5, and workstation 6, and if the wakeup sequence of each workstation is determined according to the preset allocation rule, the wakeup sequence of each workstation is as follows: workstation 3, workstation 2, workstation 5, workstation 1, workstation 6, workstation 4; if the start time of a certain wakeup period is 02 hours 03 minutes 5 seconds, the start time of the sub wakeup period of the workstation 3 in the wakeup period is 02 hours 03 minutes 0 seconds, the start time of the sub wakeup period of the workstation 2 is 02 hours 03 minutes 0.00025 seconds, the start time of the sub wakeup period of the workstation 5 is 02 hours 03 minutes 0.0005 seconds, the start time of the sub wakeup period of the workstation 1 is 02 hours 03 minutes 0.00075 seconds, the start time of the sub wakeup period of the workstation 6 is 02 hours 03 minutes 0.001 seconds, and the start time of the sub wakeup period of the workstation 4 is 02 hours 03 minutes 0.00125 seconds.

As can be seen from the above description, when the number of the first type of workstations increases and falls within a different number range from the saved first number, the wake-up period becomes large; determining the adjusted access limiting window parameters of the first type of workstations according to the increased wake-up period, thereby ensuring that the first type of workstations cannot mutually occupy resources due to the increase of the number of the first type of workstations to cause data transmission delay; further, when the number of the first type of workstations decreases and falls within a different number range from the saved first number, the wake-up period becomes smaller; and determining the adjusted access limiting window parameters of the first type of workstations according to the reduced awakening period, so that excessive resources are not occupied on the basis of ensuring the effective data transmission of the first type of workstations, and the waste of resources is avoided.

Further, as another embodiment, the access limiting window parameter of the first type of workstation is adjusted in response to a change in the number of second type of workstations; correspondingly, the target types include a first type and a second type, and as shown in fig. 4, the foregoing step 102-4 includes:

and step 102-4-4, counting the second number of the workstations of the first type and the third number of the workstations of the second type according to the type information of the workstations included in the response data.

Specifically, first target response data with the type information of the first type is screened from the received response data, and the number of the first target response data is counted and used as a second number of the first type of workstations; and screening second target response data with the type information of the second type from the received response data, and counting the quantity of the second target response data to be used as a third quantity of the workstations of the second type.

Correspondingly, as shown in fig. 4, the foregoing step 102-6 includes:

step 102-6-4, determining a second number of workstations of the first type and a third number of workstations of the second type as access information;

further, as shown in fig. 4, step 106 includes:

step 106-8, if yes, determining a target quantity range to which the third quantity belongs in a plurality of preset quantity ranges;

106-10, determining a target awakening period according to the target quantity range;

step 106-12, determining the adjusted access restriction window parameter for the first type of workstation based on the second number and the target wake-up period.

number range (one)	Wakeup period (millisecond)
		1-5	3.25
6-10	2.35
		11-15	1.50
16-20	0.75

It can be seen that the wake-up period is reduced when the third number of workstations of the second type is increased and falls within a different number range than the saved first number of workstations of the second type. Because the workstation of the second type can receive and transmit data at any time without accessing the limiting window, when the number of the workstations of the second type is increased greatly, resources can be preempted, so that the workstation of the first type can only wait for the next sub-wakeup period to transmit data, namely is in a competition avoidance state, and the data transmission of the workstation of the first type is delayed; by reducing the total wake-up period, the sub-wake-up period of each workstation of the first type is reduced, so that the next sub-wake-up period can be quickly entered without waiting for too long time, and the problem of data transmission delay is solved.

Further, the implementation process of step 106-8 to step 106-12 is similar to the implementation process of step 106-2 to step 106-6, and reference may be made to the foregoing related description, and repeated points are not described herein again.

As yet another embodiment, the adjusted access restriction window parameter for a first type of workstation is determined based on the number of workstations of the first type and the number of workstations of the second type, where the target types are the first type and the second type; correspondingly, as shown in fig. 5, on the basis of the foregoing steps 102-4-4 and 102-6-4, the step 106 includes:

step 106-14, if yes, determining a target quantity range in a plurality of preset quantity ranges according to the second quantity and the third quantity;

specifically, a first quantity range to which the second quantity belongs in a plurality of preset quantity ranges is determined; determining a second quantity range to which the third quantity belongs in a plurality of preset quantity ranges; if the first quantity range is the same as the second quantity range, determining the first quantity range as a target quantity range; if the first quantity range is different from the second quantity range, determining a fourth quantity according to a preset weighting parameter, the second quantity and the third quantity; determining a number range to which the fourth number belongs among a plurality of preset number ranges as a target number range. The process of determining the fourth quantity may be set in practical application according to the preset weighting parameter, the second quantity and the third quantity, and this is not specifically limited in this specification. For example, the fourth quantity + the third quantity, or the fourth quantity + the third quantity; wherein n and m are preset weighting parameters.

106-16, determining a target awakening period according to the target quantity range;

step 106-18, determining the adjusted access restriction window parameter for the first type of workstation based on the second number and the target wake-up period.

The implementation process of steps 106-16 and steps 106-18 can refer to the foregoing related description, and the repetition points are not described herein again.

Therefore, the adjusted access limiting window parameter of the first type of workstation is determined according to the access information and the preset adjusting rule, so that the adjusted access limiting window parameter is sent to the first type of workstation in the subsequent process, the first type of workstation updates the access limiting window parameter, the problem of resource occupation caused by the increase of the number of workstations and further data transmission delay is avoided, and unnecessary resource occupation is avoided when the number of workstations is reduced.

Further, in order to enable the AP device to accurately determine whether to adjust the access limiting window parameter of the first type of station when the AP device acquires the access information of the station next time, after the AP device determines to adjust the access limiting window parameter of the first type of station, the method further includes: the saved first number is replaced with a counted number of workstations of the target type.

And step 108, sending the adjusted access limiting window parameter to the first type of workstation, so that the first type of workstation updates the currently stored access limiting window parameter into the adjusted access limiting window parameter.

Specifically, an association relationship is established between the workstation identification of each first type of workstation and the determined corresponding adjusted access limiting window parameter, a parameter adjustment message is generated according to each established association relationship, and the parameter adjustment message is broadcasted; when each first type workstation acquires the parameter adjusting message, acquiring the associated adjusted access limiting window parameter from the parameter adjusting message according to the workstation identification of the workstation, and updating the currently stored access limiting window parameter into the acquired adjusted access limiting window parameter. Or the response data comprises IP addresses of the workstations, and the AP equipment respectively sends corresponding parameter adjustment messages to the workstations of the first type according to the IP addresses of the workstations of the first type; and when each first type of workstation receives the parameter adjusting message sent by the AP equipment, acquiring the adjusted access limiting window parameter from the received parameter adjusting message, and updating the currently stored access limiting window parameter into the acquired adjusted access limiting window parameter.

In the embodiment of the present specification, access information of a workstation accessing an AP device is acquired, and when determining to adjust an access restriction window parameter of a first type of workstation according to the access information, an adjusted access restriction window parameter of the first type of workstation is determined according to the acquired access information and a preset adjustment rule; the adjusted access limiting window parameter is then sent to the first type of workstation, so that the first type of workstation updates the currently saved access limiting window parameter to the adjusted access limiting window parameter. Therefore, based on the acquired access information, the adjustment of the access limiting window is realized, the effective data transmission of each workstation is ensured, and the problems of data transmission delay, resource waste and the like caused by the change of the number of the workstations are effectively avoided.

Based on the same technical concept, as an extension of the foregoing embodiments, one or more embodiments of the present specification further provide another access limiting window adjusting method, and fig. 6 is a schematic flow chart of the another access limiting window adjusting method provided by one or more embodiments of the present specification, as shown in fig. 6, the method may specifically include the following steps:

Further, in order to determine whether to adjust an access restriction window parameter of the video entry device, in one or more embodiments of the present specification, a first number of access devices of a target type obtained last time is further saved, so as to determine a change situation of the number of access devices of the target type according to the first number and the number of currently obtained access devices of the target type, and further determine whether to adjust the access restriction window parameter of the video entry device according to the change situation of the number. Specifically, step 204 includes:

Therefore, when the number of the video recording devices in the first working state is increased and is in a different number range from the stored first number, the awakening period is increased; determining the adjusted access limiting window parameters of the video input equipment in the first working state according to the increased awakening period, so that the video input equipment in the first working state cannot mutually occupy resources due to the increase of the number of the video input equipment in the first working state, and data transmission delay is caused; further, when the number of the video recording devices in the first working state is reduced and the number of the video recording devices in the first working state is different from the stored first number, the awakening period is shortened; and determining the adjusted access limiting window parameters of the video recording equipment in the first working state according to the reduced awakening period, so that excessive resources cannot be occupied on the basis of ensuring the effective data transmission of the video recording equipment in the first working state, and the resource waste is avoided.

As another embodiment, the response data returned by the video entry device further includes working state information, and the access limiting window parameter of the video entry device in the first working state is adjusted according to the change condition of the total number of the video entry device in the second working state and the alarm sensing device; correspondingly, the target types include a video input device in a first working state, a video input device in a second working state, and an alarm sensing device, and the foregoing step 202-4 may include:

step 206-16, determining a target wake-up period according to the target number range;

and 206-18, determining the adjusted access limiting window parameter of the video recording equipment in the first working state according to the second quantity and the target awakening period.

The implementation of the above step 206-14 to step 206-18 is similar to the implementation of the above step 106-14 to step 106-18, and reference may be made to the foregoing related description, which is not repeated herein.
