DETAILED DESCRIPTION OF THE EMBODIMENTS
[0012] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.
[0013] The terms "first", "second", etc. in the specification of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. generally belong to the same category, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the associated objects before and after.
[0014] The following will, in conjunction with the accompanying drawings, elaborate in detail on the electronic device and display control method provided in the embodiments of the present application through specific embodiments and their application scenarios.
[0015] Figure 1 Shown is a communication method provided in the embodiments of the present application, which is executed by a terminal. As Figure 1 shown, the method includes the following steps.
[0016] S102: The terminal obtains an initial task set to be executed, and the initial task set includes at least two data transmission tasks.
[0017] Among them, the above-mentioned at least two data transmission tasks include at least one of a workstation type task and an access point type task. The workstation type task indicates that the terminal acts as a workstation for data transmission, and the access point type task indicates that the terminal acts as a wireless access point for data transmission.
[0018] In the embodiments of the present application, the number of data transmission tasks in the initial task set is not specifically limited. For example, it can be 10, 50, or 100, etc.
[0019] In the embodiments of the present application, the terminal executing the above communication method can work as an AP (Access Point), such as working as a router, or can work as a STA (Station), such as working as a mobile terminal. In different data transmission tasks, the working role of the terminal is different. Therefore, different data transmission tasks can be classified as workstation type or access point type.
[0020] S104: Perform time-sharing processing on the channel where the terminal is located based on the total number of tasks in the initial task set to obtain at least two time slices for task allocation.
[0021] In the embodiments of the present application, the number of channels where the terminal is located can be multiple, and the specific number is not limited. For example, it can be 2, 5, or 10, etc.
[0022] Among them, time-sharing processing means dividing time into multiple time-sharing periods, and the same processing flow is executed in each time-sharing period. The time-sharing period can be set to a specific value according to needs, such as 50 ms or 100 ms, etc., and is not specifically limited. For example, if the time-sharing period is 100 ms, then time-sharing processing means executing the same processing flow every 100 ms.
[0023] In the embodiments of the present application, in any one of the multiple divided time-sharing periods, the time-sharing period can be divided into multiple time slices, and each time slice is used to allocate to a data transmission task.
[0024] Among them, the number of time slices within a time-sharing period is determined according to the total number of tasks in the initial task set. For example, if the time-sharing period is T and the total number of tasks in the initial task set is N, then the time-sharing period T can be divided into T / N time slices.
[0025] S106: At the beginning of the i-th time slice, obtain a candidate task set based on the initial task set. The candidate task set only includes all access point type tasks and workstation type tasks that need to be awakened in the initial task set.
[0026] Among them, 1 ≤ i ≤ N, and i is a positive integer, and N is the total number of tasks in the initial task set.
[0027] In the embodiments of this application, there are multiple time-sharing periods, and there are also multiple time slices within each time-sharing period. The same processing flow is repeated in sequence for each time-sharing period, and the same processing flow is repeated in sequence for each time slice within each time-sharing period. Therefore, taking the current time slice i to be allocated (any time slice within the current time-sharing period) within the current time-sharing period (any time-sharing period) as an example, the steps of the above communication method are described, and no further statement will be made later.
[0028] In one implementation manner, before the above terminal executes the target task within the i-th time slice, it may further include: Read the current working state of the workstation type task in the initial task set. If the current working state of the workstation type task is the wake-up state, add the workstation type task to the candidate task set.
[0029] It is worth mentioning that the access point type tasks in the initial task set can also be added to the candidate task set, so that a candidate task set only including all access point type tasks and workstation type tasks that need to be awakened can be obtained.
[0030] In another implementation manner, before the above terminal executes the target task within the i-th time slice, it may further include: For the data transmission tasks of the workstation type in the initial task set, read the current working state of the data transmission tasks. If the current working state of the data transmission tasks is the sleep state, delete the data transmission tasks based on the initial task set and retain the remaining data transmission tasks, so as to obtain the candidate task set.
[0031] In one embodiment, the working state of the above workstation-type task is a bitmap with 2 digits. Among them, one bit represents whether the terminal has data to send or has no data to send, and the other bit represents whether there is data of the wireless access point to receive or there is no data of the wireless access point to receive. When the two bits indicate that there is data to send or there is data of the wireless access point to receive, the corresponding working state is the wake-up state. When the two bits indicate that there is no data to send and there is no data of the wireless access point to receive, the corresponding working state is the sleep state.
[0032] Among them, the working state of the above workstation-type task can be updated in real time by listening to beacon frames. Exemplarily, the updated result can be recorded in the task working state set, so that the latest working state can be obtained by reading this task working state set.
[0033] S108: The terminal executes the target task in the i-th time slice, and the target task is determined based on the execution times and priorities of each task to be executed in the candidate task set.
[0034] Among them, before the above terminal executes the target task in the i-th time slice, it may further include: Determine the target task in the candidate set based on the execution times and priorities of the data transmission tasks.
[0035] In one embodiment, the above determining the target task in the candidate set based on the execution times and priorities of the data transmission tasks may include: Determine the data transmission task with the least execution times based on the candidate set; among the data transmission tasks with the least execution times, use the data transmission task with the highest priority as the target task.
[0036] It is worth mentioning that the above data transmission task with the least execution times refers to the data transmission task with the least execution times in the current time-sharing period.
[0037] Among them, the above data transmission task with the least execution times may be one or more, and is not specifically limited. The data transmission task with the highest priority is one.
[0038] In the embodiments of the present application, each data transmission task corresponds to a unique priority, and different data transmission tasks can be identified through the priority.
[0039] In the embodiments of the present application, one channel executes one data transmission task. Among them, the channel used by the data transmission task has been determined when it is generated. Therefore, it can be understood that each data transmission task has a corresponding channel, that is, there is a definite corresponding relationship between the data transmission task and the channel.
[0040] In an embodiment of the present application, after the terminal executes a target task within the i-th time slice, the following may further be included: Determine whether there is a data transmission task that has been executed and completed. If so, delete the data transmission task that has been executed and completed from the initial task set and the candidate task set.
[0041] In an embodiment of the present application, when i is equal to N, after the terminal executes a target task within the i-th time slice, the following may further be included: If there is a new data transmission task, add the new data transmission task to the initial task set, and reset the execution times of all data transmission tasks in the initial task set to zero.
[0042] Wherein, i being equal to N represents the end of the current time-sharing period, and then the next time-sharing period starts, and the same processing flow continues to be executed.
[0043] In an embodiment of the present application, the terminal supports a first wireless path and a second wireless path. The target task is executed by the first wireless path, and the second wireless path is used to monitor beacon frames.
[0044] In an embodiment of the present application, both the first wireless path and the second wireless path are used for wireless data transmission. Among them, the second wireless path alternately operates in a sleep state and a wake-up state.
[0045] In one implementation, the first wireless path may support multiple modulation methods, which are not specifically limited. For example, it may support a modulation method of 1KQAM (1 Kilo Quadrature Amplitude Modulation, 1024-order quadrature amplitude modulation), or support a modulation method of 256-QAM, or support a modulation method of 4KQAM, etc.
[0046] In one implementation, the second wireless path supports modulation methods of OFDM (Orthogonal Frequency Division Multiplexing), DSSS (Direct Sequence Spread Spectrum), or CCK (Complementary Code Keying).
[0047] In the method provided by the embodiment of the present application, at the beginning of a certain time slice, all access point type tasks and workstation type tasks that need to be woken up are added to the candidate task set, and the target task to be executed is determined from the candidate task set based on the execution times and priorities. Through the above process, it is possible to avoid allocating time slices to the workstation type tasks in the sleep state, the time-sharing mechanism is more optimized and reasonable, the utilization rate of the channel can be improved, the transmission delay caused by improper time slice allocation can be reduced, and the tasks with higher priorities can be executed and responded earlier.
[0048] Figure 2 Another communication method provided by the embodiment of the present application is shown, which is executed by a terminal. As Figure 2 shown, the method includes the following steps.
[0049] S202: The terminal obtains an initial task set to be executed, and the initial task set includes at least two data transmission tasks.
[0050] In the embodiment of the present application, the data transmission task refers to a task of sending data or receiving data, and does not include the task of listening to beacon frames.
[0051] Among them, the above at least two data transmission tasks include at least one of workstation type tasks and access point type tasks. The workstation type task indicates that the terminal performs data transmission as a workstation, and the access point type task indicates that the terminal performs data transmission as a wireless access point.
[0052] For example, connecting to a router to access the Internet, local area network streaming, etc. belong to the workstation type; P2P Go, personal hotspot, etc. belong to the access point type.
[0053] In the embodiment of the present application, the above initial task set can be expressed as follows: . Among them, is a workstation type task, is an access point type task.
[0054] S204: Perform time sharing on the channel where the terminal is located based on the total number of tasks in the initial task set to obtain at least two time slices for task allocation.
[0055] For example, if the total number of tasks in the initial task set is N, within a time-sharing period T, T can be evenly divided into N time slices, and each data transmission task is allocated one time slice. That is to say, each data transmission task can be allocated an execution time of T / N.
[0056] S206: At the beginning of the i-th time slice, obtain a candidate task set based on the initial task set. The candidate task set only includes all access point type tasks and the workstation type tasks that need to be woken up in the initial task set.
[0057] Wherein, 1≤i≤N, i is a positive integer, and N is the total number of tasks in the initial task set.
[0058] In the embodiment of the present application, the data transmission task of the access point type needs to process the data requests sent from other devices in real time and needs to be awakened at least once within a time-sharing period. Therefore, when allocating each time slice in the current time-sharing period, the access point type tasks are added to the candidate task set.
[0059] In the embodiment of the present application, for the workstation type tasks in the initial task set, if the current working state of the workstation type task is the awakened state, the workstation type task is added to the candidate task set.
[0060] Since the candidate task set does not include the workstation type tasks in the sleep state, it can be ensured that such tasks are not allocated time slices, thereby avoiding the situation of low channel utilization rate and unreasonable time slice allocation caused by allocating time slices to the sleep state tasks, realizing reasonable scheduling, resource optimization, improving the channel utilization rate, and reducing the transmission delay.
[0061] In the embodiment of the present application, the working state of the above workstation type task is a bitmap with 2 digits. Among them, one bit represents whether the terminal has data to send or has no data to send, and the other bit represents whether there is data to receive from the wireless access point or there is no data to receive from the wireless access point. In the case where the two bits represent that there is data to send or there is data to receive from the wireless access point, the corresponding working state is the awakened state.
[0062] This way of using a bitmap to represent the working state can cover various combined states of terminal transceiver, and can identify all working states with less resources, which is simple and efficient.
[0063] Exemplarily, the 0th bit can represent whether the terminal has data to send or has no data to send, and the 1st bit can represent whether there is data to receive from the wireless access point or there is no data to receive from the wireless access point. Alternatively, the 0th bit can represent whether there is data to receive from the wireless access point or there is no data to receive from the wireless access point, and the 1st bit can represent whether the terminal has data to send or has no data to send. The embodiment of the present invention does not make specific limitations on this.
[0064] For example, the task working state set is S . Among them, it includes n working states , corresponding to n workstation type tasks. It is a bitmap with 2 bits. When the 0th bit is 1, it indicates that the terminal has data to send; when the 0th bit is 0, it indicates that the terminal has no data to send. When the 1st bit is 1, it indicates that the terminal needs to receive data sent by the wireless access point; when the 1st bit is 0, it indicates that the terminal does not need to receive data, that is, the wireless access point has no data to send. Therefore, when is 0, the corresponding workstation type task is in the sleep state. When is 1, 2, or 3, the corresponding workstation type task is in the wake-up state.
[0065] In one implementation, the working state of the above workstation type task can be updated in real time by listening to beacon frames.
[0066] In the embodiments of the present application, the principle for the STA to listen to beacon frames is as follows: After the STA enters the power-saving mode, the AP caches the data sent to the STA during the sleep period of the STA. The STA wakes up regularly and listens to the beacon frames sent by the AP to check whether there is cached data in the TIM (Traffic Indication Map) of the beacon frame. If the TIM indicates which STAs have cached data through the AID (Association ID), these STAs send PS-Poll (Power Save-Poll) frames to request data. After receiving the PS-Poll frame, the AP distributes the cached data to the corresponding STA according to the AID in the received PS-Poll frame. After receiving the data, the STA re-enters the sleep mode. Among them, the AID is a unique identifier assigned by the AP to each associated STA.
[0067] Figure 3 shows a schematic flow diagram of a wireless device listening to beacon frames provided by the embodiments of the present application. As Figure 3 shown, the wireless device with AID = 1 listens to beacon frames during the listening wake-up time and is in the sleep state at other times. When the router indicates in the TIM of a beacon frame through AID = 1 that the wireless device has data to receive, the wireless device sends a PS-Poll frame to request the data. After receiving the PS-Poll frame, the AP distributes the cached data to the wireless device. After receiving the data, the wireless device re-enters the sleep state.
[0068] S208: Determine the data transmission task with the least number of executions based on the candidate set.
[0069] Among them, the least number of executions mentioned above means the least number of executions within the current time-sharing period.
[0070] In the embodiments of the present application, the data transmission task with the least number of executions in the current time-sharing period may be one or more, and there is no specific limitation. For the convenience of recording, the number of executions of the task may also be represented in the form of a set. For example, the number of executions of each data transmission task in the current time-sharing period may be represented as: set C . In this set C, are the number of executions of the workstation type tasks respectively, are the number of executions of the access point type tasks respectively.
[0071] This method of determining the data transmission task with the least number of executions can enable as many data transmission tasks as possible to obtain scheduling opportunities fairly, allocate time slices more reasonably, and greatly improve the utilization rate of the channel.
[0072] S210: Among the data transmission tasks with the least number of executions, the data transmission task with the highest priority is used as the target task.
[0073] Among them, the current time slice, that is, the i-th time slice, can be allocated to the target task.
[0074] In the embodiments of the present application, each data transmission task corresponds to a unique priority, and different data transmission tasks can be identified through the priority. Among them, the priority of the data transmission task can be set as a positive integer. For example, the smaller the value, the higher the priority, or the larger the value, the higher the priority. The embodiments of the present invention do not make specific limitations on this.
[0075] This method of determining the target task with the highest priority can ensure that the task with the highest priority obtains the allocation of time slices first, can be executed and responded earlier, ensure that more important and urgent tasks can be executed first, and realize the reasonable scheduling of tasks.
[0076] In the embodiments of the present application, the priority set of the data transmission task can be represented as follows: P . In this set P, are the priorities of the workstation type tasks respectively, are the priorities of the access point type tasks respectively.
[0077] S212: The terminal executes the target task in the i-th time slice.
[0078] In the embodiments of the present application, the terminal supports a first wireless path and a second wireless path. The target task is executed by the first wireless path, and the second wireless path is used to listen for beacon frames.
[0079] Among them, both the first wireless path and the second wireless path are used for wireless data transmission. The second wireless path alternates between a sleep state and a wake state due to listening to beacon frames. Therefore, compared with the method where both wireless paths are always in a working state, one of the wireless paths alternates between a sleep state and a wake state, greatly reducing power consumption.
[0080] Based on this method, the second wireless path can be implemented using a circuit with a lower cost than the first wireless path, such as designing a baseband and front-end circuit with a lower cost. Compared with the method where both wireless paths use the same cost, it can greatly save hardware costs, reduce power consumption, and be more power-saving.
[0081] In one implementation, the first wireless path can support multiple modulation methods, such as supporting modulation methods of 1KQAM, 4KQAM, or 256-QAM. The second wireless path can support modulation methods of OFDM, DSSS, or CCK. Among them, the circuit costs of 1KQAM, 4KQAM, or 256-QAM are higher, and the circuit costs of OFDM, DSSS, or CCK are lower. The real-time request for data transceiver is realized through the high-cost first wireless path, and the listening of beacon frames is realized through the low-cost second wireless path. The combination of the two achieves the effects of reasonable design, cost saving, and power consumption reduction.
[0082] S214: Determine whether there is a data transmission task that has been completed. If so, delete the completed data transmission task from the initial task set and the candidate task set.
[0083] This method of deleting the completed data transmission task can update the initial task set and the candidate task set in a timely manner, ensuring the effectiveness and accuracy of subsequent task allocation.
[0084] S216: When i is equal to N, if there is a new data transmission task, add the new data transmission task to the initial task set and reset the execution times of all data transmission tasks in the initial task set to zero.
[0085] This method of adding a new data transmission task in a new time-sharing period realizes the dynamic allocation of data transmission tasks, ensures the timely allocation of new data transmission tasks, and improves the processing efficiency.
[0086] Figure 4 Shows another schematic diagram of the communication method flow provided by the embodiment of the present application. As Figure 4As shown, there are an initial task set Q, a task working status set S, a task execution count set C, and a task priority set P. Among them, the priorities in set P are sorted according to actual requirements. The sleep-wake status of the data transfer tasks of STA in set S is updated in real time. All counts in set C are set to 0 before the tasks start. Define a variable Ntemp to represent the current remaining number of tasks. The initial value of Ntemp is set to the number N of data transfer tasks in set Q during initialization. Define i as the time slice serial number in the current time-sharing period.
[0087] First, when the i-th time slice starts, retain all data transfer tasks of the AP type and delete the data transfer tasks in the sleep state of the STA type to obtain a new set Q1. Among them, deleting the data transfer tasks in the sleep state of the STA type can also be understood as retaining the data transfer tasks that need to be woken up. Whether a data transfer task is in the sleep state can be judged by whether the value in set S is 0. If it is 0, it represents the sleep state; if it is non-0, it represents the wake state.
[0088] Secondly, select the data transfer task with the least execution count in the current time-sharing period from set Q1 to obtain a new set Q2. The purpose of this step is to enable all data transfer tasks to obtain scheduling opportunities as fairly as possible. Select the data transfer task with the highest priority in set Q2 as the target task to obtain the execution permission for the i-th time slice. In this i-th time slice, switch the corresponding channel to execute the target task. When each data transfer task obtains a time slice, its corresponding execution count staCount or apCount needs to be incremented by 1, that is, the execution count is incremented by 1.
[0089] After a time slice is executed, check whether there is any data transfer task that has ended. If so, delete the information of this task from all sets, and Ntemp is subtracted by the number of ended tasks. Then, judge whether set Q is empty. If Q is empty, it means that there are no data transfer tasks that need to be executed currently, and then exit. If Q is not empty, continue with the allocation process of the next time slice until the count of time slices reaches N.
[0090] When the count of time slices has reached N, this round of time-sharing period has ended. Judge whether there are new data transfer tasks added. If so, add the information such as the newly added data transfer tasks, their priorities, working statuses, and execution counts to each set to obtain the updated sets Q, S, C, and P. And update the total number of tasks N, and clear all execution counts in set C. Then, the wireless device starts the process of the next time-sharing period.
[0091] In the method provided by the embodiment of the present application, at the beginning of a certain time slice, all access point type tasks and workstation type tasks that need to be woken up are added to the candidate task set, and the target task to be executed is determined from the candidate task set based on the execution times and priorities. Through the above process, it is possible to avoid allocating time slices to workstation type tasks in the sleep state, the time-sharing mechanism is more optimized and reasonable, the utilization rate of the channel can be improved, the transmission delay caused by improper time slice allocation can be reduced, the anti-interference ability is stronger, and tasks with higher priorities can be executed and responded earlier.
[0092] The above is the communication method provided by the embodiment of the present invention. Based on the same idea, the embodiment of the present invention also provides a communication device, as Figure 5 shown. The communication device includes: an acquisition module 501, a time-sharing module 502, a screening module 503, and a communication module 504.
[0093] The acquisition module 501 is used to acquire an initial task set to be executed. The initial task set includes at least two data transmission tasks.
