Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The power adjustment method provided by the embodiment of the application can be applied to the application environment shown in fig. 1. As shown in fig. 1, the application environment includes a terminal 110 and a server 120. Wherein the terminal 110 communicates with the server 120 through a network. When the terminal 110 receives the downlink data packet sent by the server 120, the terminal 110 may obtain downlink transmit power of the downlink data packet sent by the server 120 and downlink receive power of the downlink data packet received by the terminal 110. The terminal 110 may calculate the power attenuation of the downlink data packet during transmission according to the downlink transmit power and the downlink receive power. The terminal 110 may obtain a power threshold, where the power threshold is used to indicate a lowest uplink received power for the server 120 to receive the uplink data packet. The terminal 110 may adjust the uplink transmission power of the terminal 110 for transmitting the uplink data packet according to the power attenuation and the power threshold. The Terminal 110 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and other devices, the Terminal 110 may also be a cable Modem cm (cable Modem), the server 120 may be implemented by an independent server or a server cluster composed of a plurality of servers, and the server 120 may also be a cable Modem head end device cmts (cable Modem Terminal systems).
In one embodiment, as shown in fig. 2, there is provided a power adjustment method, comprising the steps of:
In this embodiment, the Terminal may be a cable Modem CM (cable Modem), the server may be a cable Modem head end device CMTS (cable Modem Terminal systems), and the CMTS may send downstream packets to the CM. The downstream packets may include signals sent by the CMTS to the CM. The CMTS may send downstream packets to the CM according to a downstream transmit power, which may be a value of a signal strength of the downstream packets sent by the CMTS; the CM may receive downstream packets sent by the CMTS at a downstream receive power, which may be a value of the signal strength of the downstream packets received by the CM.
The downlink data packet may be used to indicate a data packet sent by the server to the terminal. When the server sends the downlink data packet to the terminal, the server may send the downlink transmission power for sending the downlink data packet to the terminal together. The terminal can communicate with the server through the network, and when the terminal receives the downlink data packet sent by the server through the data packet sending channel, the terminal can obtain the downlink sending power of the downlink data packet sent by the server because the server sends the downlink sending power of the downlink data packet to the terminal together. The terminal may receive the downlink data packet sent by the server according to the downlink receiving power, and the terminal may obtain the downlink receiving power for receiving the downlink data packet. Specifically, a demodulator may be disposed inside the terminal, and the demodulator may be configured to detect the size of the power, and the terminal may detect the downlink receiving power for receiving the downlink data packet through the demodulator.
And step 204, calculating the power attenuation of the downlink data packet in the transmission process according to the downlink transmitting power and the downlink receiving power.
In the process of sending a downlink data packet to a terminal through a data packet transmission channel, a server often has power attenuation. After acquiring the downlink transmitting power of the downlink data packet sent by the server and the downlink receiving power of the downlink data packet received by the terminal, the terminal can calculate the power attenuation of the downlink data packet in the transmission process. Specifically, the terminal may subtract the downlink transmit power of the received downlink data packet sent by the server from the downlink receive power of the received downlink data packet, so as to obtain the power attenuation of the downlink data packet in the transmission process.
Step 206, a power threshold is obtained, where the power threshold is used to indicate a lowest uplink receiving power for the server to receive the uplink data packet.
The power threshold may be a minimum value of uplink received power for the server to receive the uplink data packet, and may be a value determined at the time of configuring the server. For example, the power threshold may be 20dbmv (decibels to 1 millivolt). The uplink data packet is used for indicating a data packet sent by the terminal to the server.
The server may send the power threshold to the terminal, so that the terminal obtains the lowest value of the uplink receiving power of the server for receiving the uplink data packet. The value of the power threshold may be-10 dbmv, -7dbmv, 0dbmv, 8dbmv, 20dbmv, etc., which is not limited herein.
And step 208, adjusting the uplink transmitting power of the terminal for transmitting the uplink data packet according to the power attenuation and the power threshold value.
After obtaining the power attenuation and the power threshold value, the terminal may adjust uplink transmission power of an uplink data packet sent by the terminal. The larger the power attenuation is, the larger the power threshold value is, and the larger the uplink transmission power of the terminal for transmitting the uplink data packet is. Specifically, the terminal may use a sum of the power attenuation and the power threshold as a basis for adjusting the uplink transmission power for sending the uplink data packet.
In this embodiment, when the terminal receives a downlink data packet sent by the server, the downlink transmission power of the downlink data packet sent by the server and the downlink receiving power of the downlink data packet received by the terminal are obtained, the power attenuation of the downlink data packet in the transmission process is calculated according to the downlink transmission power and the downlink receiving power, and a power threshold is obtained, where the power threshold is used to represent the lowest value of the uplink receiving power of the uplink data packet received by the server, and the uplink transmission power of the uplink data packet sent by the terminal is adjusted according to the power attenuation and the power threshold. The computer equipment calculates the power attenuation by acquiring the downlink transmitting power of the server and the downlink receiving power of the terminal, adjusts the uplink transmitting power of the terminal according to the power attenuation and the power threshold value, and the terminal does not need to send different powers for multiple times to adjust the uplink transmitting power which is finally sent to the server, so that the efficiency of adjusting the uplink transmitting power of the terminal can be improved.
In one embodiment, the provided power adjustment method may further include a process of calculating power attenuation, where the specific process includes: acquiring first amplification data of a downlink data packet sent by a server, wherein the first amplification data is used for representing power amplification of the downlink data packet in a transmission process; and calculating the power attenuation of the downlink data packet in the transmission process according to the downlink transmitting power, the downlink receiving power and the first amplification data.
In the process of sending the downlink data packet to the terminal through the transmitting channel, the server can generate power attenuation and power amplification. Specifically, the transmission channel may include an amplifier for power amplification, and when the server wants the terminal to send a downlink data packet, the server may amplify downlink received power of the terminal when receiving the downlink data packet through the amplifier in the transmission channel.
In the process of sending the downlink data packet to the terminal, the server may send the information such as the power multiple of the downlink data packet amplified by the amplifier in the transmission channel to the terminal. The terminal may obtain first amplified data of a downlink data packet sent by the server.
After the terminal acquires the first amplification data, the power attenuation of the downlink data packet in the transmission process can be calculated according to the acquired downlink transmitting power, downlink receiving power and the first amplification data. Specifically, the terminal may add the first amplified data to the downlink transmit power, and then subtract the downlink receive power to calculate the power attenuation of the downlink data packet in the transmission process.
In this embodiment, the terminal sends, by obtaining first amplification data of a downlink data packet sent by the server, the first amplification data being used to indicate power amplification of the downlink data packet in the transmission process, and calculates power attenuation of the downlink data packet in the transmission process according to the downlink transmission power, the downlink reception power, and the first amplification data. The server sends the first amplification data and the downlink transmitting power to the terminal, the terminal detects the downlink receiving power through the demodulator, and the terminal can accurately calculate the power attenuation of the downlink data packet in the transmission process according to the first amplification data, the downlink transmitting power and the downlink receiving power, so that the accuracy of the calculated power attenuation can be improved.
In an embodiment, the provided power adjustment method may further include a process of adjusting power, where the specific process includes: acquiring second amplification data, wherein the second amplification data is used for representing power amplification of an uplink data packet in a transmission process; and adjusting the uplink transmitting power of the uplink data packet sent by the terminal according to the power attenuation, the power threshold value and the second amplification data.
The second amplification data is used for representing power amplification of the uplink data packet in the transmission process, and the uplink data packet is used for representing a data packet sent by the terminal to the server, so the second amplification data is used for representing power amplification of the terminal in the process of sending the uplink data packet to the server.
When receiving a downlink data packet sent by a server, a terminal can mark a transmitting channel occupied by the server when sending the downlink data packet, and before sending an uplink data packet to the server, the terminal can search the marked transmitting channel and send the uplink data packet to the server through the marked transmitting channel. The transmitting channel can contain an amplifier for power amplification, and the server sends amplified data of a downlink data packet passing through the amplifier to the terminal as first amplified data; and the terminal sends an uplink data packet to the server to amplify the data of the amplifier into second amplified data. The first amplified data and the second amplified data are generated by an amplifier in the transmit channel.
After the terminal acquires the second amplification data, the uplink transmission power for transmitting the uplink data packet may be adjusted according to the power attenuation, the power threshold value, and the second amplification data.
In this embodiment, the terminal adjusts the uplink transmission power of the uplink data packet sent by the terminal according to the power attenuation, the power threshold and the second amplification data by acquiring the second amplification data, where the second amplification data is used to represent the power amplification of the uplink data packet in the transmission process. Because the power attenuation, the power threshold value and the second amplification data are all important factors influencing the uplink transmission power of the uplink data packet sent by the terminal, the terminal adjusts the uplink transmission power through the factors, and the accuracy of power adjustment can be improved.
In another embodiment, the provided power adjustment method may further include a process of adjusting power, where the specific process includes: calculating target uplink transmitting power according to the power attenuation, the power threshold value and the second amplification data; and the control terminal sends the uplink data packet according to the target uplink transmitting power.
The target uplink transmission power may be used to indicate the uplink transmission power of the adjusted terminal for transmitting the uplink data packet. The terminal can calculate the target uplink transmission power according to the power attenuation, the power threshold value and the second amplification data, and can send the uplink data packet to the server according to the target uplink transmission power.
In this embodiment, the terminal calculates the target uplink transmission power according to the power attenuation, the power threshold and the second amplified data, and controls the terminal to transmit the uplink data packet according to the target uplink transmission power. The terminal does not need to send different powers for multiple times to adjust the uplink transmitting power finally sent to the server, and the target uplink transmitting power is directly obtained according to the power attenuation, the power threshold value and the second amplified data, so that the efficiency of adjusting the uplink transmitting power of the terminal can be improved.
As shown in fig. 3, in an embodiment, the provided power adjustment method may further include a process of restarting the terminal, and the specific steps include:
The power interval may be preset and used to indicate an interval of uplink transmission power for the terminal to transmit the uplink data packet to the server. The power interval may be determined according to the performance of the terminal, for example, when the terminal is a CM, the corresponding power interval may be 17dbmv to 54dbmv, and when the uplink transmission power of the CM exceeds the interval of 17dbmv to 54dbmv, the CM cannot be successfully on-line.
304, when the target uplink transmitting power exceeds the power interval, displaying a first prompt message; the first prompt information is used for prompting that the target uplink transmission power is unqualified.
The terminal may compare the obtained target uplink transmission power with the power interval, and obtain a comparison result. And when the comparison result obtained by the terminal is that the target uplink transmitting power exceeds the power interval, the terminal can display the first prompt message. Specifically, the first prompt information displayed by the terminal may be a pop-up prompt box, a display warning light, a vibration, and the like, which is not limited herein. And the first display information is used for prompting that the target uplink transmission power is unqualified.
And after the terminal compares the obtained target uplink transmitting power with the power interval, when the obtained comparison result is that the target uplink transmitting power does not exceed the power interval, the terminal can send an uplink data packet to the server according to the target uplink transmitting power.
Step 306, restarting the terminal according to the first prompt message, and returning to execute the step of obtaining the downlink transmitting power of the downlink data packet sent by the server and the downlink receiving power of the downlink data packet received by the terminal when the terminal receives the downlink data packet sent by the server.
And after the terminal shows the first prompt message, the terminal can perform restarting operation. After the terminal is restarted, the downlink data packet sent by the server can be detected again, and when the terminal receives the downlink data packet sent by the server, the terminal can obtain the downlink transmitting power of the downlink data packet sent by the server and the downlink receiving power of the downlink data packet received by the terminal.
In this embodiment, the terminal obtains a preset power interval, when the target uplink transmission power exceeds the power interval, displays first prompt information, where the first prompt information is used to prompt that the target uplink transmission power is not qualified, restarts the terminal according to the first prompt information, and returns to execute the steps of obtaining the downlink transmission power of the downlink data packet sent by the server and the downlink receiving power of the downlink data packet received by the terminal when the terminal receives the downlink data packet sent by the server. When the target uplink transmitting power is unqualified, the terminal acquires the downlink transmitting power and the downlink receiving power again in a restarting mode, and adjusts the uplink transmitting power until the target uplink transmitting power is qualified, so that the terminal can be prevented from sending an uplink data packet to the server according to the unqualified uplink transmitting power.
In an embodiment, the provided power adjustment method may further include a process of switching an operating mode, where the specific process includes: acquiring the display times of the first prompt message; when the display times are larger than a preset display threshold value, displaying second prompt information; the second prompt message is used for prompting the abnormity of the data packet transmitting channel; and switching the working mode of the terminal into a low power consumption mode according to the second prompt message.
The presentation threshold may be preset and used to indicate a maximum value of the number of times of presenting the first prompt information, and the presentation threshold may be a specific numerical value. For example, the presentation threshold may be 3 times, 5 times, 8 times, etc. The second prompt information may be used to prompt that the transmission channel of the data packet is abnormal, and the mode of displaying the second prompt information by the terminal may be a pop-up prompt box, a display warning light, a vibration, and the like, which is not limited herein. Wherein the intensity of the second prompt message prompt may be higher than the intensity of the first prompt message prompt.
The terminal can count the number of times of displaying the first prompt message through the counter. The terminal can obtain the display times of the first prompt message from the counter. The terminal can compare the obtained display times of the first prompt message with a display threshold value, and obtain a comparison result. The terminal can decide whether to display the second prompt message according to the comparison result. And when the obtained comparison result shows that the display times are greater than a preset display threshold value, the terminal can display the second prompt message. After the terminal displays the second prompt message, the working mode of the terminal can be switched to a low power consumption mode, and the low power consumption mode can reduce the power consumption of the terminal. After displaying the second prompt message, the terminal may send the message indicating that the data packet transmission channel is abnormal to the operator, so that the operator can locate the abnormal channel.
In this embodiment, the terminal displays the second prompt information by acquiring the display times of the first prompt information when the display times is greater than a preset display threshold, the second prompt information is used for prompting that the data packet transmission channel is abnormal, and the working mode of the terminal is switched to the low power consumption mode according to the second prompt information.
