Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
After the terminal device corresponding to the user is started, the corresponding cell can be accessed, and then the terminal device can obtain corresponding data by sending a request to the cell, so that various services such as making a call, surfing the internet, sending short messages and the like can be realized. The method comprises the steps that for each uplink scheduling request sent by terminal equipment, a cell sends corresponding uplink resource allocation information through a downlink control channel, so that the terminal equipment sends data to be uploaded to the cell according to the uplink resource allocation information; therefore, as the number of users in the mobile network increases, the resources of the downlink control channel also become strained, and further, the embodiment of the present invention provides a data processing method to save the resources of the downlink control channel.
One of the core ideas of the embodiment of the present invention is that a cell does not return a corresponding uplink resource allocation message through a downlink control channel for each uplink scheduling request, but calculates a delay parameter corresponding to the uplink resource allocation message, then determines a corresponding delay duration according to the delay parameter, and sends the uplink resource allocation message after the delay duration is reached; and further, the times of sending the uplink resource allocation message are reduced, so that the downlink control channel resources are saved.
Referring to FIG. 1, a flow diagram of the steps of one data processing method embodiment of the present invention is shown; the method comprises the following specific steps:
And 102, calculating a delay parameter corresponding to the uplink resource allocation message.
In the embodiment of the invention, when the terminal equipment needs to upload data, an uplink scheduling request can be sent to a cell, and after the cell receives the uplink scheduling request sent by the terminal equipment, corresponding uplink resources can be allocated to the terminal equipment; after the uplink resource allocation is completed, an uplink resource allocation message corresponding to the uplink scheduling request can be generated. After the uplink resource allocation message is generated, calculating a delay parameter corresponding to the uplink resource allocation message, determining delay time corresponding to the uplink resource allocation message according to the delay parameter, and sending the uplink resource allocation message when the delay time is up; and further saves the downlink control channel resources. The number of available downlink control channel resources of the cell is different in different time periods, and correspondingly, the degrees of downlink control channel resources required to be saved are different, for example, when the available downlink control channel resources of the cell are sufficient, the uplink resource allocation message does not need to be saved, that is, the uplink resource allocation message does not need to be sent in a delayed manner, or the uplink resource allocation message is sent after the uplink resource allocation message is delayed for a short time period; for example, when the available downlink control channel resources of the cell are relatively tight, the uplink resource allocation message needs to be saved, and at this time, the uplink resource allocation message can be sent after a longer delay time. When the delay time corresponding to the uplink resource allocation message is long, for terminal devices with poor air interface environments, the uplink delay of the terminal devices is too long due to poor uplink air interface capability of the terminal devices, and user perception is affected; therefore, in order to ensure the uplink delay of the terminal equipment in a poor air interface environment and effectively save the downlink control channel resources, the delay parameters can be determined according to the available downlink control channel resources and the uplink air interface capability of the terminal equipment. In the embodiment of the present invention, the utilization rate of the downlink control channel unit of the cell may be used to represent the number of available downlink control channel resources of the cell, that is, the higher the utilization rate of the downlink control channel unit is, the more tense the downlink control channel resources of the cell are, and conversely, the lower the utilization rate of the downlink control channel unit is, the more sufficient the downlink control channel resources of the cell are; and representing the uplink air interface capability by adopting the uplink maximum data volume, wherein the uplink air interface capability is stronger when the uplink maximum data volume is larger, and the uplink air interface capability is worse when the uplink maximum data volume is smaller. Therefore, the maximum uplink data volume of the terminal device and the utilization rate of the downlink control channel unit of the cell can be determined as the delay parameter, so as to determine the delay duration according to the delay parameter.
Step 103, if the delay parameter meets a first preset condition, determining the delay time length to be a preset time length.
And 104, if the delay parameter meets a second preset condition, calculating the delay time according to the delay parameter.
In the embodiment of the present invention, the delay duration may be dynamically adjusted according to the delay parameter, that is, a condition that the delay duration satisfies is determined, if the delay parameter satisfies a first preset condition, the preset duration is determined as the delay duration, and if the delay parameter satisfies a second preset condition, the delay duration is calculated according to the delay parameter. The first preset condition and the second preset condition can be preset according to requirements, and the preset time can also be preset according to requirements, for example, the preset time range is 0-320 ms. Of course, the first preset condition, the second preset condition and the preset duration can be adjusted in real time.
And 105, sending the uplink resource allocation message to the terminal equipment after judging that the delay time length is reached.
And then judging whether the delay time length is reached, if the delay time length is reached, sending the uplink resource allocation message to the terminal equipment, and further reducing the frequency of sending the uplink resource allocation message, thereby saving downlink control channel resources.
After receiving an uplink scheduling request of a terminal device and generating an uplink resource allocation message corresponding to the uplink scheduling request, a cell of the embodiment of the invention calculates a delay parameter corresponding to the uplink resource allocation message, then determines a delay duration of the uplink resource allocation message according to the delay parameter, and sends the uplink resource allocation message to the terminal device after judging that the delay duration is reached; and the uplink resource allocation message is not immediately sent to the terminal equipment, so that the frequency of sending the uplink resource allocation message is reduced, and the downlink control channel resource is further saved. Further, the delay duration is dynamically adjusted, that is, if the delay parameter meets a first preset condition, the preset duration is determined as the delay duration; if the delay parameter meets a second preset condition, calculating the delay time length according to the delay parameter; wherein the delay parameters include: the maximum uplink data volume of the terminal equipment and the utilization rate of the downlink control channel unit of the cell can be combined with the uplink air interface capability of the terminal equipment and the downlink resource utilization rate of the cell, the delay time length can be adjusted, and the downlink control channel resource of the cell can be saved more effectively.
Referring to FIG. 2, a flow diagram of the steps of another data processing method embodiment of the present invention is shown; the method comprises the following specific steps:
In the embodiment of the invention, the uplink radio frame allocates resources for the SR, and when the terminal equipment needs to upload data, the SR resources can be adopted to carry information so as to send an SR request to a cell; after receiving an uplink radio frame sent by a terminal device, a cell detects whether an SR report exists in the uplink radio frame, and when the SR report is detected, a corresponding uplink resource allocation message can be generated. Wherein, before the cell generates the corresponding uplink resource allocation message for the uplink scheduling request, the cell has completed processing of all the historically received SRs.
Then, a delay parameter corresponding to the uplink resource allocation message may be calculated, where the delay parameter includes: the maximum uplink data volume of the terminal equipment and the utilization rate of a downlink control channel unit of the cell; that is, the maximum uplink data amount of the terminal device may be calculated, specifically refer to step 202-step 204, and the utilization rate of the downlink control channel unit of the cell may be calculated, specifically refer to step 205.
Step 202, determining an actual Signal to Interference plus Noise Ratio (SINR) and a target SINR of the terminal device.
And step 204, determining the maximum uplink data volume of the terminal equipment according to the maximum uplink PRB number and the maximum MCS index value.
In the embodiment of the present invention, a cell may calculate an actual SINR of the terminal device according to a received channel sounding reference signal, where the SINR is a ratio of the strength of a received useful signal to the strength of a received interference signal (noise and interference); and determining an uplink target SINR, wherein the target SINR is the maximum SINR value received by the cell. Because the transmitting power of the terminal equipment is limited, in order to ensure that the receiving SINR of a single PRB of a cell reaches the target SINR, the number of PRBs in an uplink is limited; therefore, the maximum number of PRBs can be calculated according to the actual SINR and the target SINR, and the MCS index value can be calculated. Then, according to the maximum uplink PRB number and the maximum MCS index value, determining the maximum uplink data size of the terminal equipment, namely, indexing by adopting the maximum uplink PRB number and the maximum MCS index value, and inquiring the corresponding maximum uplink data size; and further determining the uplink air interface capability of the terminal equipment.
After the corresponding uplink maximum data volume is inquired, smooth calculation can be carried out on the inquired uplink maximum data volume by adopting historical uplink maximum data volume information, and the value of the smooth calculation is determined as the uplink maximum data volume of the terminal equipment, so that the accuracy of the uplink maximum data volume of the terminal equipment is ensured. In the embodiment of the invention, the formula of the smoothing calculation is as follows:
Cn＝α*Cn-1+(1-α)*Ci
wherein, the CnIs the terminal equipmentThe maximum uplink data volume, wherein alpha is a smooth forgetting factor and ranges from 0 to 1, and Cn-1Is the maximum uplink data volume of the terminal device obtained last time, CiIs the maximum amount of data upstream for the query.
Calculating the utilization rate of a downlink Control Channel Element (CCE) of the cell, namely calculating the ratio of the number of the utilized CCE to the allocated CCE; wherein, the higher the CCE utilization rate is, the more tense the downlink control channel resources of the corresponding cell are, and vice versa.
Then, according to the delay parameter, determining a delay duration corresponding to the uplink resource allocation message, which is specifically as follows:
and step 206, judging whether the delay parameter meets a first preset condition.
The embodiment of the invention can compare the uplink maximum data volume with a data volume threshold and judge whether the uplink maximum data volume is smaller than the data volume threshold; and comparing the utilization rate of the downlink control channel unit with a utilization rate threshold, judging whether the utilization rate of the downlink control channel unit is smaller than the utilization rate threshold, and further judging whether the delay parameter meets a first preset condition according to the judgment result. Specifically, if the uplink maximum data volume is smaller than a data volume threshold, and/or the utilization rate of the downlink control channel unit is smaller than a utilization rate threshold, it is determined that the delay parameter meets a first preset condition; if the uplink maximum data volume is larger than a data volume threshold and the utilization rate of the downlink control channel unit is larger than a utilization rate threshold, determining that the delay parameter meets a second preset condition; that is, if the delay parameter does not satisfy the first preset condition, it may be determined that the delay parameter satisfies the second preset condition, where the utilization threshold and the data amount threshold may be set as required. If the delay parameter meets the first preset condition, step 207 may be executed, and if the delay parameter meets the second preset condition, step 208 may be executed, which is as follows:
if the uplink maximum data volume is smaller than the data volume threshold, determining that the uplink air interface capability of the terminal device is poor, that is, the air interface environment where the terminal device is located is poor; and if the uplink maximum data volume is larger than the data volume threshold, determining that the uplink air interface capability of the terminal equipment is strong, namely the air interface environment where the terminal equipment is located is better. If the CCE utilization rate is lower than a utilization rate threshold, determining that the downlink control channel resources of the cell are sufficient; otherwise, if the CCE utilization rate is higher than the utilization rate threshold, determining that the downlink control channel resources of the cell are in shortage.
And step 207, determining the delay time length as a preset time length.
If the delay parameter meets the first preset condition, it is determined that the uplink air interface capability of the terminal device is poor, and/or it is determined that the cell downlink control channel resource is sufficient, at this time, the uplink resource allocation message may not be sent with delay, or the uplink resource allocation message may be sent with a shorter delay, so that it is determined that the delay time is the preset time. In the embodiment of the present invention, the preset duration may be 0ms, that is, the uplink resource allocation message is not delayed to be sent, or may be a value greater than 0ms, that is, the uplink resource allocation message is delayed to be sent according to the preset duration.
And step 208, calculating the delay time length according to the delay parameters.
If the delay parameter meets a second preset condition, determining that the uplink air interface capability of the terminal equipment is strong, determining that the downlink control channel resource of the cell is in shortage, and delaying to send back the uplink resource allocation message for a longer time so as to relieve the downlink control channel resource of the cell; at this time, the delay duration may be determined according to the preset duration, the maximum uplink data amount, and the utilization rate of the downlink control channel unit, which are as follows:
calculating a ratio of the uplink maximum data volume to the downlink control channel unit utilization rate, after obtaining the ratio, calculating a product of the ratio and a scale factor, and determining the preset time length and a maximum value in the product as the time length for delaying the return of the uplink resource allocation message, wherein the delayed time length can be calculated by adopting the following formula:
wherein, T is2For the duration of the delay, T1The time length is preset, the Y is the maximum uplink data volume, the X is the utilization rate of the downlink control channel unit, and the n is a scale factor.
And step 209, judging whether the delay time length is reached.
After the delay time length is determined, a corresponding timer can be set according to the delay time length, and then whether the delay time length is reached can be judged by judging whether the timer is overtime. If it is determined that the delay time period has not been reached, the step 209 may be continuously executed; if it is determined that the delay period is reached, step 210 may be performed.
After the cell determines that the delay time length is reached, the cell can send the uplink resource allocation message to the terminal device, so that the terminal device uploads data according to the uplink resource allocation message.
If the uplink resource allocation message is not received within the default response duration of the terminal equipment, the uplink scheduling request is sent to the cell again; and when the delay time is longer than the default response time corresponding to the uplink scheduling request and the delay time is not reached, the cell may receive the plurality of uplink scheduling requests sent by the terminal equipment. Therefore, in order to reduce the number of times of sending the uplink resource allocation message and judge that the delay time is not reached, the cell ignores the uplink scheduling request sent by the terminal equipment; and then, a plurality of uplink scheduling requests of the terminal equipment can be processed in a centralized way, so that the times of returning uplink resource allocation messages are reduced, and downlink control channel resources are saved.
After receiving an uplink scheduling request of a terminal device and generating an uplink resource allocation message corresponding to the uplink scheduling request, a cell of the embodiment of the invention calculates a delay parameter corresponding to the uplink resource allocation message, then determines a delay duration of the uplink resource allocation message according to the delay parameter, and sends the uplink resource allocation message to the terminal device after judging that the delay duration is reached; and the uplink resource allocation message is not immediately sent to the terminal equipment, so that the frequency of sending the uplink resource allocation message is reduced, and the downlink control channel resource is further saved. Further, the delay duration is dynamically adjusted, that is, if the delay parameter meets a first preset condition, the preset duration is determined as the delay duration; if the delay parameter meets a second preset condition, calculating the delay time length according to the delay parameter; wherein the delay parameters include: the maximum uplink data volume of the terminal equipment and the utilization rate of the downlink control channel unit of the cell can be combined with the uplink air interface capability of the terminal equipment and the downlink resource utilization rate of the cell, the delay time length can be adjusted, and the downlink control channel resource of the cell can be saved more effectively. Secondly, when the uplink maximum data volume is determined, indexing is carried out according to the uplink maximum PRB number and the maximum MCS index value, after the corresponding uplink maximum data volume is inquired, the historical uplink maximum data volume information is adopted to carry out smooth calculation on the inquired uplink maximum data volume, so that the uplink maximum data volume is determined, and the accuracy of determining the delay time is further improved.
And if the cell receives the uplink scheduling request sent by the terminal equipment when the delay time length is reached, the cell can ignore the uplink scheduling request, but return the uplink resource scheduling message to the terminal equipment after the delay time length is reached, so that not only is downlink control channel resources saved, but also resources for processing the uplink scheduling request by the cell are saved.
