In a general design, taking a game service of a mobile terminal as an example, the relevant characteristics of the game service are as follows: long connections, small data packets, low traffic, low latency requirements, low fault tolerance, and sensitivity to changes in the wireless network environment. Due to the sensing capability range of normal people, when the delay in the game service reaches the level of 100ms, the user can obviously feel the card pause, and the operation is not flexible; when the delay in the game reaches the 200ms level, the operation of the user and the game perception feedback can not be synchronized basically, and the user experience is seriously influenced. As can be seen from the network architecture shown in fig. 1A, the process of the mobile terminal interacting with the network device for game service data includes access network delay from the mobile terminal to the air interface of the network, and time consumption for transmitting IP data from the access network to the game server.

In view of the above situation, an embodiment of the present application provides a parameter adjusting method applied to a mobile terminal, including: determining a reference channel quality parameter CQI of a serving cell associated with the mobile terminal; acquiring Reference Signal Received Power (RSRP) of the mobile terminal for receiving the downlink data of the serving cell; adjusting the reference CQI to be a target CQI according to the RSRP; and sending the target CQI to network equipment, wherein the target CQI is used for indicating the network equipment to determine the data block size of the downlink data.

Embodiments of the present application will be described below with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart illustrating a parameter adjusting method according to an embodiment of the present application, which is applied to a mobile terminal, and which can be executed by an application processor, a baseband processor, or a SoC of the mobile terminal, for example, and is not limited herein. As shown in the figure, the parameter adjusting method includes:

s201, the mobile terminal determines a reference Channel Quality parameter (CQI) of a serving cell associated with the mobile terminal.

The serving cell is a serving cell to which the mobile terminal is currently connected, or a serving cell to which the mobile terminal is to be switched to connect.

The mobile terminal may determine the reference channel quality parameter of the serving cell associated with the mobile terminal by first measuring a Signal-to-Interference plus NOISE Ratio (SINR) (or Signal-to-NOISE Ratio (SNR)) and a Reference Signal Received Power (RSRP)), and then determining a corresponding CQI value as a reference CQI when the BLER is less than 10% according to a mapping table of pre-stored SINR (or SNR, RSRP, etc.) and BLER.

The SINR refers to a ratio of the strength of the received useful signal to the strength of the received interference signal (noise and interference).

The CQI is an information indication of the channel quality, represents the quality of the current channel and corresponds to the signal-to-noise ratio of the channel, and has a value range of 0-31, wherein the CQI is regulated to have a value of 1-15 in the LTE system, the larger the value is, the better the quality of the current channel is represented, the smaller the value is, and the worse the quality of the current channel is represented.

S202, the mobile terminal obtains Reference Signal Received Power (RSRP) of the mobile terminal for receiving the downlink data of the service cell.

The reference signal received power RSRP is associated with current location information, that is, the reference signal received power RSRP of the mobile terminal for the serving cell at the current location.

S203, the mobile terminal adjusts the reference CQI to be a target CQI according to the RSRP.

The strategy for adjusting the reference CQI as the target CQI according to the RSRP parameter is various, and may be adjusted according to a history adjustment record, a preset corresponding relationship between the RSRP and the CQI, or the like, for example, and is not limited herein.

S204, the mobile terminal sends the target CQI to network equipment, and the target CQI is used for indicating the network equipment to determine the data block size of downlink data.

The network device may be a base station, for example, an LTE base station or an NR base station (also referred to as a gNB base station).

After receiving the target CQI, the network device may determine the size of a data block in downlink data transmission according to the value of the target CQI, and a specific implementation manner of determining the size of the data block in downlink data transmission according to the target CQI is as follows: firstly, determining a modulation mode corresponding to a target CQI, determining a code rate according to the modulation mode, and then calculating the size of a data block according to the following formula: and the bit number of the information in the data block is the total bit number of the physical channel, namely the code rate.

It can be seen that, in the embodiment of the present application, a mobile terminal first determines a reference channel quality parameter CQI of a serving cell associated with the mobile terminal, then obtains a reference signal received power RSRP of downlink data of the serving cell received by the mobile terminal, then adjusts the reference CQI to be a target CQI according to the RSRP, and finally sends the target CQI to a network device, where the target CQI is used to instruct the network device to determine a data block size of the downlink data. Therefore, the mobile terminal adjusts the channel quality parameter CQI according to the obtained RSRP, which is beneficial to realizing dynamic adjustment of the channel quality parameter and improving the intelligence of adjusting the CQI, and the adjusted target CQI is used for indicating the network equipment to dynamically adjust the size of the data block of the downlink data sent to the mobile terminal, thereby being beneficial to improving the decoding success rate of the mobile terminal.

In one possible example, the method further comprises:

and detecting that a target application program runs on the foreground of the mobile terminal, wherein the target application program can be a game application program, a video application program and the like, and is not limited herein. Illustratively, the running interface of the target application is a multi-user Online Battle Arena (MOBA) scene interface.

The mobile online tactical competition can be understood as multi-person real-time online competitive competition, and is characterized by real-time performance, online networking, multi-person competition and the like.

In specific implementation, the mobile terminal can analyze a plurality of data packets through sampling of the baseband processor, identify an MOBA scene of a target application program running in the foreground through attributes such as format of the data packets, and acquire scene information sent by the foreground application program through the application processor, so that an operating system can timely know the MOBA scene of the target application program running in the foreground, and the application processor is not limited uniquely here. That is to say, the triggering condition for the mobile terminal to execute the step S201 may be that the mobile terminal detects that the current operation scene is the MOBA scene, so as to implement the exclusive optimization control for the MOBA scene.

As can be seen, in this example, when the foreground operating interface is the MOBA, due to the real-time property of this kind of scenario, the network resource needs to be large, and therefore, the value of the RSRP adjustment CQI is obtained in this scenario to notify the network device to adjust the data block, which is beneficial to reducing the network delay of the MOBA scenario and avoiding the scenario being stuck.

In one possible example, the adjusting the reference CQI to a target CQI according to the RSRP comprises:

when the RSRP is smaller than or equal to a preset threshold value, adjusting the reference CQI to be a first target CQI, wherein the first target CQI is smaller than the reference CQI; or when the RSRP is larger than the preset threshold value, adjusting the reference CQI to be a second target CQI, wherein the second target CQI is larger than the reference CQI.

The preset threshold may be-95 dBm, -105dBm, etc., which is not limited herein. When the RSRP is less than or equal to the preset threshold, it may indicate that a weak signal scenario is present, and when the RSRP is greater than the preset threshold, it may indicate that a strong signal scenario is present.

The first target CQI and the second target CQI may be values preset in the mobile terminal by a developer, or may also be target values corresponding to RSRP selected by the mobile terminal according to a history, which is not limited herein.

It can be seen that, in this example, when the mobile terminal determines that the mobile terminal is currently in a weak signal scenario, the CQI is adjusted to be that the first target CQI is smaller than the reference CQI, the CQI is adjusted to be smaller in the weak signal scenario and sent to the network device, which is beneficial for the network device to send a smaller data block to the mobile terminal, which is beneficial for improving the decoding success rate of the mobile terminal, and in a strong signal scenario, the CQI is adjusted to be that the second target CQI is larger than the reference CQI, the CQI is adjusted to be larger in the strong signal scenario and sent to the network device, which is beneficial for the network device to send a larger data packet to the mobile terminal, which is beneficial for improving the speed of data traffic.

In this possible example, the adjusting the reference CQI to be the first target CQI includes:

detecting position information of the mobile terminal;

determining the first target CQI according to the position information;

adjusting the reference CQI to the first target CQI.

The implementation manner of determining the first target CQI according to the location information may be various, and may be determining a CQI corresponding to a historical record matched with the current location and having a decoding success rate greater than a preset success rate as the first target CQI, or determining a mapping relationship between the location information and the CQI, where the mapping relationship between the location information and the CQI may be preset because the location information may strongly relate to the signal quality of the location, and determining the CQI corresponding to the location information as the first target CQI according to the location information, which is not limited uniquely herein.

As can be seen, in this example, when the RSRP is less than or equal to the preset threshold, that is, in a weak signal quality scenario, the mobile terminal adjusts the first target CQI to be less than the reference CQI, which is beneficial to instructing the network device to send a smaller data packet to the mobile terminal, and is beneficial to increasing the decoding success rate, and the first target CQI is determined according to the location information, which is beneficial to improving the accuracy of CQI adjustment.

In this possible example, the determining the first target CQI from the location information includes:

acquiring a historical CQI record associated with the position information;

and determining the CQI with the block error rate BLER smaller than a preset rate as the first target CQI according to the historical CQI record.

Wherein the preset ratio may be 15%, 20%, etc., and is not limited herein. The historical CQI record at least comprises a CQI value, position information, a block error rate BLER and the like, the first target CQI is determined according to the historical CQI record, the block error rate is smaller than a preset ratio and can indicate that the decoding success rate is high, the decoding does not need to be repeated again under the weak signal state, and the first target CQI can be a value of any CQI of which the block error rate BLER is smaller than the preset ratio or an average value of the CQI of which the block error rate BLER is smaller than the preset ratio.

Therefore, in this example, the mobile terminal determines, according to the historical CQI record associated with the location information, the first target CQI that the block error rate BLER is less than the preset block error rate, and the algorithm is simple and easy to implement, and is beneficial to improving the intelligence of parameter adjustment.

In one possible example, the adjusting the reference CQI to be a second target CQI includes:

detecting the average frame rate of the MOBA scene in a preset time period;

when the average frame rate is detected to be larger than a preset frame rate, determining the second target CQI according to the average frame rate;

adjusting the reference CQI to the second target CQI.

The preset frame rate may be 60FPS, 65FPS, etc., and is not limited herein. The frame rate represents the number of frames per second or how many times per second the graphics processor can update in a MOBA scene. The larger the frame rate is, the more pictures need to be uploaded per second, the higher the required code rate is, and the code rate refers to the number of bits (bits) transmitted per second, that is, the faster the required data transmission rate is, therefore, the second target CQI greater than the reference CQI can be sent to the network device, so that the network device increases the data transmission rate.

The implementation manner of determining the second target CQI according to the average frame rate may be various, for example, the second target CQI may be determined according to a mapping relationship between a preset average frame rate and a CQI, or the second target CQI with a data transmission rate greater than a preset rate may be determined according to a history adjustment record under the condition that the current average frame rate is determined, which is not limited herein.

As can be seen, in this example, when the RSRP is greater than the preset threshold, that is, in a strong signal scene, and when the average RSRP is greater than the preset frame rate, the mobile terminal adjusts the second target CQI to be greater than the reference CQI, so that the network device increases the data transmission rate to increase the code rate, which is beneficial to improving the picture quality of the MOBA scene and reducing the picture congestion of the MOBA scene.

In this possible example, the determining the second target CQI according to the average frame rate includes:

determining a target code rate according to the average frame rate;

determining the adjustment quantity of the reference CQI according to the target code rate;

and determining the second target CQI according to the adjustment amount of the reference CQI.

The larger the frame rate is, the more pictures need to be uploaded every second, and the higher the required code rate is, so that the required target code rate is determined according to the current average frame rate, the adjustment amount of the reference CQI is determined according to the target code rate, and then the second target CQI is determined, which is beneficial to improving the accuracy of the second target CQI.

The specific implementation manner of determining the adjustment amount of the reference CQI according to the target code rate may be determining the adjustment amount of the reference CQI according to a difference between the target code rate and a current code rate, and the manner of determining the adjustment amount of the reference CQI according to the difference between the target code rate and the current code rate may be a mapping relationship between a preset code rate difference and a CQI adjustment amount, determining the adjustment amount of the reference CQI according to the mapping relationship between the code rate difference and the CQI adjustment amount, or determining the mapping relationship between the code rate difference and the CQI adjustment amount according to historical data by using an artificial intelligence module in the mobile terminal, and then determining the adjustment amount of the reference CQI, which is not limited uniquely herein.

As can be seen, in this example, when detecting that the average frame rate is greater than the preset frame rate, the mobile terminal determines a target code rate according to the average frame rate, and determines an adjustment amount of the reference CQI according to the target code rate, so as to determine a second target CQI, which is beneficial to improving accuracy of CQI adjustment.

S303, when the RSRP is smaller than or equal to a preset threshold value, the mobile terminal detects the position information of the mobile terminal.

S304, the mobile terminal acquires the historical CQI record related to the position information.
