The following description will be given by taking as an example a method for an uplink data splitting apparatus based on multi-user access to perform uplink data splitting based on multi-user access. Referring to fig. 1, the uplink data partitioning method based on multi-user access includes:
s101: and sending a pre-access instruction to all terminals in the group.
In the embodiment of the present invention, the receiving end of the uplink data is, for example, a base station or a server. The group is used for indicating all terminals which can establish communication connection with the receiving end in the embodiment of the invention. The terminal comprises a smart phone, a tablet personal computer, a computer, intelligent wearable equipment and the like. And the receiving end actively sends a pre-access instruction to all terminals in the group, wherein the pre-access instruction is used for indicating the authorization of the receiving end to the terminals and indicating that the receiving end can receive uplink data at the moment.
S102: receiving an access signal fed back by at least one terminal based on the pre-access instruction; the access signal is provided with terminal characteristics, and the terminal characteristics comprise response time, path loss, a terminal unique code and transmission characteristics; the transmission characteristics include a retransmission rate.
And the terminal immediately feeds back an access signal after receiving the pre-access instruction. The information that the access signal is used to deliver to the receiving end includes successful acknowledgements and handshakes. In addition, the access signal further includes terminal characteristics, which can characterize a plurality of performances of the terminal, including response time and path loss, and a unique code of the terminal, which is used for representing the uniqueness of the terminal. The response time refers to the time when the terminal successfully receives the pre-access instruction and reacts, and the path loss represents the loss generated in the process of uploading data from the terminal to the receiving terminal. The retransmission rate indicates a probability of retransmission occurring within a certain period of time when the terminal has performed data transmission in the past.
S103, judging whether the terminal meets a preset condition or not according to the terminal characteristics, and acquiring an uploading queue task of the terminal when the terminal meets the preset condition, wherein the uploading queue task comprises at least one datum waiting to be uploaded and the data capacity of each datum waiting to be uploaded; the data carries data characteristics.
The method comprises the steps of screening the accessed terminals according to conditions, eliminating partial terminals which do not meet the conditions, reducing the number of the terminals accessed simultaneously, and avoiding the problem of reduced transmission quality caused by insufficient transmission resources due to overlarge number of the terminals accessed simultaneously. And for the terminal which does not accord with the preset condition, the terminal is removed from the connection with the base station, so that the transmission efficiency is improved.
Further, when the terminal is judged to meet the preset conditions according to the terminal characteristics, the transmission process is adjusted according to the uploading queue task of the terminal, and the data of the terminal are received through the transmission process.
And for the screened terminals, acquiring the uploading queue task of each terminal, and adjusting the transmission process according to the different sizes of the tasks so as to improve the transmission efficiency.
As a preferred embodiment, the method for determining whether the terminal meets a preset condition according to the terminal characteristics, and adjusting a transmission process according to an upload queue task of the terminal when the terminal meets the preset condition includes: judging whether the terminal meets a first preset condition or not according to the terminal characteristics; acquiring the number of terminals meeting a first preset condition, and acquiring the response time and path loss of all terminals meeting the first preset condition when the number meets a second preset condition; and calculating the transmission indexes of the terminals according to the response time and the path loss, sequencing the transmission indexes from large to small, selecting the terminals with the transmission indexes positioned at the top M as target terminals, and adjusting the transmission process according to the uploading queue task of the target terminals, wherein M is a preset value and is a positive integer.
As an example of the embodiment of the present invention, the first preset condition is that the response time is less than T seconds. Or, the first preset condition is that the path loss is lower than the threshold, or the first preset condition is that the first N received terminals correspond to the access signals, which may be other conditions. The first preset condition is used for primarily screening a part of terminals.
For example, the total number of the accessed terminals is S, the number of the terminals meeting the first preset condition is S1, the terminals meeting the first preset condition are screened again, and whether the terminals meet the second preset condition is determined, where the second preset condition is used to represent the number of the terminals, that is, whether S1 meets the second preset condition is determined. For example, the second preset condition is S2, and only when S1 is less than or equal to S2, it indicates that the terminal meets the second preset condition.
And if the S1 is larger than the S2, re-screening according to other conditions so that the number of the terminals meets the requirement of the S2.
In the embodiment of the present invention, when the number satisfies a second preset condition, the response time and the path loss of all terminals that satisfy the first preset condition are obtained, so as to calculate the transmission index of the terminal according to the response time and the path loss.
S104: and allocating a terminal storage address symbol according to the terminal unique code and the uploading queue task, wherein the storage address symbol corresponds to at least one buffer area, and the buffer area comprises at least one storage interval.
A plurality of cache regions are configured at a receiving end, each cache region corresponds to a storage address symbol, and a storage position can be quickly found through the storage address symbols, so that data can be quickly acquired. Each buffer area is often divided into a plurality of storage areas so as to reasonably utilize the buffer area and simultaneously store a plurality of data. For each memory region, there is also a corresponding address symbol. In the embodiment of the invention, the storage address symbol actually distributed to the slave terminal can correspond to the storage interval of the buffer area.
S105: and calculating the number of the division blocks of the data based on the retransmission rate, the data capacity of the data and the capacity of the storage interval, forming a division mode of the terminal according to the number of the division blocks, transmitting the division mode to the terminal to receive the data of the terminal, and dividing the data according to the division mode by the data.
After the above five steps are performed, the method may further include: and judging whether the time difference of receiving the data through the transmission process of two adjacent times meets the congestion condition, and increasing the transmission process of uploading the data by the terminal when the congestion condition is met. And if the time difference of the data received at two adjacent times is greater than the preset value, the congestion condition is met.
In order to better adapt to the storage interval, facilitate data transmission, reduce retransmission rate, and improve transmission efficiency, the present embodiment segments data, and automatically selects different segmentation methods to segment data according to different retransmission rates, data capacities, and capacities of the storage intervals.
Specifically, the method comprises the following steps:
judging whether the data capacity is larger than the capacity of the storage interval or not; when the data capacity is larger than the capacity of the storage interval, calculating a difference value between the data capacity and the capacity of the storage interval, acquiring the proportion of the difference value in the capacity of the storage interval, and calculating the number of the divided blocks of the data according to the proportion. For example, if the ratio of the difference value to the capacity of the storage section is one fourth, the data is divided into four blocks. When the data capacity is smaller than or equal to the capacity of the storage interval and the retransmission rate is larger than a first threshold value, setting the number of the segmentation blocks according to a first preset rule; when the data capacity is smaller than or equal to the capacity of the storage interval and the data capacity is larger than a second threshold value, setting the number of the segmentation blocks according to a second preset rule; and when the data capacity is smaller than or equal to the capacity of the storage interval, and when the retransmission rate is larger than the first threshold and the data capacity is larger than the second threshold, setting the number of the segmentation blocks according to a third preset rule.
Wherein the first preset rule is as follows: acquiring a data frame node for retransmitting the data according to the historical data characteristics and the historical transmission characteristics of the data uploaded by the terminal; and recording the data frame nodes as segmentation nodes. For example, in the first preset rule, 10 sets of historical data are selected in total, and statistics and analysis are performed on the 10 sets of historical data to obtain the retransmission position of each set of data of the 10 sets of data, that is, the data frame node. And all the data frame nodes of the ten groups of data are arranged in sequence to be used as segmentation nodes, and the segmentation nodes are installed for segmentation when the data meet the conditions later. The second preset rule is as follows: and calculating the difference value between the data capacity and the second threshold value, and setting the data into segmentation nodes every other difference value. For example, if the data capacity is R, the second threshold is W, and the difference is denoted as W-R, then, in the total data capacity, the division is performed by recording as one division node every (W-R) from the first data frame. The third preset rule is as follows: acquiring a data frame node for retransmitting the data according to the historical data characteristic and the historical transmission characteristic of the data uploaded by the terminal; recording the data frame node as a first segmentation node; calculating the difference value between the data capacity and a second threshold value, and setting a second segmentation node for the data every other difference value; and sequentially arranging the first segmentation nodes and the second segmentation nodes according to the arrangement sequence of the data frames, removing the repeated first segmentation nodes or the repeated second segmentation nodes to form a third segmentation node sequence, and taking the third segmentation node sequence as a segmentation node. The third preset rule combines the first preset rule and the second preset rule, for example, the first preset rule forms a first segmentation node of a1, a2, a3, \ 8230 \ 8230;, an, and the second preset rule forms a second segmentation node of b1, b2, b3, \ 8230; \ 8230, bn, then the third segmentation node sequence is a combination of the first segmentation node and the second segmentation node in the order, and the order is the sequential order of the data frames. The data positions actually corresponding to a2 and b3 are added, one of the data positions is removed, and the other data position is reserved, wherein the sequence of the third segmentation node is a1, a2, b1, b2 and a3 \8230ifa 1 is added before b1, and b1 is after a 2.
As another embodiment of the present invention, the retransmission rate is obtained by:
constructing a retransmission rate analysis model according to the historical data characteristics of the data uploaded by the terminal and the historical transmission characteristics corresponding to the historical data characteristics; and inputting the data characteristics and the transmission characteristics of the data into a retransmission rate analysis model, and outputting the retransmission rate.
A time period is taken as a reference, and a sufficient number of data transmission channels between the terminal and the receiving end and a sufficient number of data transmitted on the same data transmission channel in the time period are selected as sample capacities. The retransmission analysis model is trained by acquiring the historical transmission characteristics and the historical data characteristics, the trained retransmission analysis model can cover various characteristics, and the analysis requirements of data transmission channels with different transmission characteristics and data with different data characteristics can be met.
