It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The following describes embodiments of the present application in detail.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a transmission rate adjustment system according to an embodiment of the present application, where the transmission rate adjustment system includes: the system comprises a mobile terminal, a wireless router, a data forwarding device and a network device. The data forwarding device is connected to the network device through a network, the network device may include an access network device and a core network device, the access network device includes a base station and the like, and the core network device includes a gateway and the like. The mobile terminal is connected with the wireless router through the wireless local area network, and the wireless router is connected with the data forwarding device through the wired port. In one embodiment, a Mobile terminal may include various handheld devices, vehicle mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem with wireless communication capabilities, as well as various forms of User Equipment (UE), Mobile Station (MS), terminal Equipment (terminal device), and the like. In one embodiment, the data forwarding device may be a modem (colloquially referred to as a light cat).
Under the transmission rate adjusting system, the principle that the mobile terminal sends data to the outside is as follows: the mobile terminal sends data to the wireless router; after receiving the data sent by the mobile terminal, the wireless router sends the received data to the data forwarding equipment; after the data forwarding device receives the data sent by the wireless router, the data forwarding device processes the received data and then sends the processed data to the network device through the network.
At present, both a mobile terminal and a wireless router can support high-speed internet access, and the transmission rate of a data forwarding device is limited, so that the problem that the transmission rate of the data forwarding device is not matched with the uplink transmission rate of the mobile terminal may exist, the problem that the data forwarding device cannot timely process data transmitted by the mobile terminal forwarded by the wireless router exists, the data forwarding device loses data packets, the wireless router reduces the rate of transmitting data to the data forwarding device, and the problem that the wireless router loses data packets also exists.
In view of the above problem, in this embodiment of the present application, if the number of Transmission Control Protocol (TCP) duplicate acknowledgement messages received by the mobile terminal within a certain period of time exceeds a certain value, it indicates that the actual uplink Transmission rate of the mobile terminal is far greater than the actual Transmission rate of the data forwarding device, that is, the Transmission rates are not matched, and in this case, the actual uplink Transmission rate of the mobile terminal is adjusted to be close to the actual Transmission rate of the data forwarding device through a Transmission rate adjustment policy. Therefore, the speed of the mobile terminal sending data upwards after adjustment is close to the speed of the data forwarding equipment transmitting data, the problem that the data forwarding equipment and the wireless router discard some data due to the fact that the data forwarding equipment cannot process the data sent by the mobile terminal forwarded by the wireless router in time is solved, and the transmission efficiency of uplink transmission data of the mobile terminal is improved.
Referring to fig. 2, fig. 2 is a schematic flow chart of a transmission rate adjustment method according to an embodiment of the present application, where an execution subject is a mobile terminal, and the method includes:
step 201: and acquiring the quantity of TCP repeated confirmation messages received by the mobile terminal in a target time period.
The TCP duplicate acknowledgement message is a TCP message sent by the network device to the mobile terminal when the currently running application of the mobile terminal is stuck.
The TCP receiver receives a first confirmation message sent by the TCP sender, and if the confirmation number in the first confirmation message is the same as the confirmation number in a second confirmation message, and the second confirmation message is the confirmation message received by the TCP receiver before receiving the first confirmation message, the first confirmation message is determined to be a TCP repeated confirmation message. The TCP transmitter is used for the network equipment to transmit a TCP repeated confirmation message to the mobile terminal, and the TCP receiver is used for the mobile terminal to receive the TCP repeated confirmation message transmitted by the network equipment.
The mobile terminal receives a large amount of TCP duplicate acknowledgement messages sent by the network device under the condition that the data forwarding device cannot process the data sent by the mobile terminal forwarded by the wireless router in time.
When the mobile terminal receives a large number of TCP duplicate acknowledgement messages, it indicates that the data forwarding device cannot process data sent by the mobile terminal through the data forwarding device in time, that is, the actual transmission rate of the data forwarding device is less than the actual uplink transmission rate of the mobile terminal, at this time, the data forwarding device discards some data that cannot be processed in time, and the data forwarding device has a data packet loss problem, which further causes the wireless router to reduce the rate of transmitting data to the data forwarding device, and the wireless router also has a data packet loss problem.
When the average value of the uplink transmission rates of the mobile terminal in the second period is smaller than the average value of the uplink transmission rates of the mobile terminal in the first period, it indicates that the currently running application of the mobile terminal is stuck, and step 201 is triggered; the duration of the first time interval is the same as the duration of the second time interval, and the ending moment of the first time interval is the starting moment of the second time interval. The second time interval is a target time interval, the termination time of the target time interval is the current system time of the mobile terminal, and the duration of the target time interval can be user-defined or self-defined by the mobile terminal.
When the uplink transmission rate actually transmitted by the mobile terminal is close to the transmission rate actually transmitted by the data forwarding equipment, the number of the TCP repeated confirmation messages received by the mobile terminal is far smaller than the number of the TCP repeated confirmation messages received when the uplink transmission rate actually transmitted by the mobile terminal is far larger than the transmission rate actually transmitted by the data forwarding equipment in the same time length.
Step 202: and determining a transmission rate adjustment strategy under the condition that the number of the TCP repeated confirmation messages is larger than a first threshold, wherein the transmission rate adjustment strategy is used for adjusting the uplink transmission rate of the mobile terminal.
When the number of the TCP duplicate acknowledgement messages is greater than the first threshold, it indicates that the uplink transmission rate actually transmitted by the mobile terminal is far greater than the transmission rate actually transmitted by the data forwarding device, at this time, the data sent by the mobile terminal to the data forwarding device through the wireless router exceeds the current processing capability of the data forwarding device, the data forwarding device discards some data which cannot be processed in time, the data forwarding device has a data packet loss problem, and thus the wireless router reduces the rate of transmitting data to the data forwarding device, and the wireless router also has a data packet loss problem.
When the number of the TCP duplicate acknowledgement messages is less than or equal to the first threshold, it indicates that the uplink transmission rate actually transmitted by the mobile terminal is close to the transmission rate actually transmitted by the data forwarding device, at this time, the data forwarding device can process the data sent by the mobile terminal through the wireless router in time, and the discarded data of the data forwarding device is significantly reduced when compared with the number of the TCP duplicate acknowledgement messages is greater than the first threshold.
The transmission rate adjustment strategy comprises a first transmission rate adjustment strategy and a second transmission rate adjustment strategy.
The first threshold represents a maximum value corresponding to the number of the TCP duplicate acknowledgement messages received by the mobile terminal in the target time period when the uplink transmission rate actually transmitted by the mobile terminal is close to the transmission rate actually transmitted by the data forwarding device, that is, when the number of the TCP duplicate acknowledgement messages received by the mobile terminal in the target time period is greater than the first threshold, the uplink transmission rate actually transmitted by the mobile terminal is not matched with the transmission rate actually transmitted by the data forwarding device.
The first threshold may be user-defined, or may be user-defined by the mobile terminal, and is not limited herein.
Further, the specific implementation manner of the mobile terminal determining the first threshold value is as follows: the mobile terminal acquires a history record of TCP repeated confirmation messages, wherein the history record comprises the total number of the TCP repeated confirmation messages received by the mobile terminal in a set time period, the set time period comprises a plurality of sub-time periods, and the time length of each sub-time period is the same as that of a target time period; the mobile terminal determines the ratio of the total number of the TCP repeated confirmation messages to the number of the sub-periods of the set period, and the ratio is the first threshold.
Step 203: and adjusting the uplink transmission rate of the mobile terminal by using the transmission rate adjustment strategy, wherein the rate difference between the first uplink transmission rate actually transmitted by the adjusted mobile terminal and the transmission rate actually transmitted by the data forwarding equipment is less than or equal to a second threshold.
Under the condition that the speed difference value between the first uplink transmission speed actually transmitted by the mobile terminal and the transmission speed actually transmitted by the data forwarding equipment is smaller than or equal to a second threshold value, the first uplink transmission speed actually transmitted by the mobile terminal is matched with the transmission speed actually transmitted by the data forwarding equipment; and under the condition that the speed difference value between the first uplink transmission speed actually transmitted by the mobile terminal and the transmission speed actually transmitted by the data forwarding equipment is greater than the second threshold, indicating that the first uplink transmission speed actually transmitted by the mobile terminal is not matched with the transmission speed actually transmitted by the data forwarding equipment.
The second threshold may be user-defined, or may be user-defined by the mobile terminal, which is not limited herein.
The number of times of adjusting the uplink transmission rate of the mobile terminal by using the first transmission rate adjustment strategy and/or the second transmission rate adjustment strategy in the transmission rate adjustment strategies may be one time, two times, or multiple times.
It can be seen that, in the embodiment of the present application, if the number of TCP duplicate acknowledgement packets received by the mobile terminal within a certain period of time exceeds a certain value, it indicates that the actual uplink transmission rate of the mobile terminal is far greater than the actual transmission rate of the data forwarding device, that is, the transmission rates are not matched, and in this case, the actual uplink transmission rate of the mobile terminal is adjusted to be close to the actual transmission rate of the data forwarding device through the transmission rate adjustment policy. Therefore, the speed of the mobile terminal sending data upwards after adjustment is close to the speed of the data transmission equipment transmitting data, the problem that the data transmission equipment and the wireless router discard some data due to the fact that the data transmission equipment cannot process the data sent by the mobile terminal and transmitted by the wireless router in time is solved, and the transmission efficiency of uplink transmission data of the mobile terminal is improved.
Referring to fig. 3, fig. 3 is a schematic flow chart of a transmission rate adjustment method according to an embodiment of the present application, where an execution subject is a mobile terminal, and the method includes:
step 301: and acquiring the quantity of TCP repeated confirmation messages received by the mobile terminal in a target time period.
See the relevant description of step 201, which will not be described here.
Step 302: judging whether the number of the TCP repeated confirmation messages is larger than a first threshold value or not;
if yes, go to step 303.
If not, go to step 301.
See step 202 for a description related thereto, and will not be described here.
Step 303: and determining the message difference value between the number of the TCP repeated confirmation messages and the first threshold value.
The larger the difference of the messages is, the larger the difference of the uplink transmission rate actually transmitted by the mobile terminal and the transmission rate actually transmitted by the data forwarding device is.
Step 304: judging whether the message difference value is greater than or equal to a third threshold value;
if yes, go to step 305-step 306.
If not, go to step 307-step 308.
The number change of the TCP repeated confirmation messages is the same when the first transmission rate adjustment strategy is used for adjusting the uplink transmission rate of the mobile terminal each time, and the number change of the TCP repeated confirmation messages is the same when the second transmission rate adjustment strategy is used for adjusting the uplink transmission rate of the mobile terminal each time.
And when the third threshold value represents that the rate difference between the actual transmission rate of the uplink transmission of the mobile terminal and the actual transmission rate of the data forwarding equipment meets the requirement of using the first transmission rate adjustment strategy and the second transmission rate adjustment strategy, or the minimum value corresponding to the message difference when the first transmission rate adjustment strategy is used, namely the message difference is greater than or equal to the third threshold value, the mobile terminal determines that the transmission rate adjustment strategy is the first transmission rate adjustment strategy and the second transmission rate adjustment strategy, or the first transmission rate adjustment strategy.
The third threshold may be user-defined, or may be user-defined by the mobile terminal, which is not limited herein.
Step 305: determining a transmission rate adjustment strategy to be the first transmission rate adjustment strategy and the second transmission rate adjustment strategy or the first transmission rate adjustment strategy; the first transmission rate adjustment strategy and the second transmission rate adjustment strategy are used for reducing the uplink transmission rate of the mobile terminal, and the adjustment range of the second transmission rate adjustment strategy is smaller than that of the first transmission rate adjustment strategy.
The first transmission rate adjustment strategy may be to reduce the transmission speed of TCP packets of the mobile terminal, and the second transmission rate adjustment strategy may be to reduce the Wi-Fi frame aggregation number of the mobile terminal.
The rate value of each adjustment is the same when the first transmission rate adjustment strategy is used for adjusting the uplink transmission rate of the mobile terminal, and the rate value of each adjustment is the same when the second transmission rate adjustment strategy is used for adjusting the uplink transmission rate of the mobile terminal.
The transmission data unit of the network layer of the open communication system interconnection reference model OSI is a data packet, the transmission data unit of the data link layer of the OSI is a frame, and data of the network layer is transmitted by the data link layer, so that the adjustment range of the adjustment strategy for reducing the transmission speed of the TCP data packet of the mobile terminal is larger than that of the adjustment strategy for reducing the aggregation number of Wi-Fi frames of the mobile terminal.
In the process of adjusting the uplink transmission rate of the mobile terminal by using the transmission rate adjustment strategy, the transmission rate actually transmitted by the data forwarding device is kept unchanged.
If the message difference is equal to a first target value, determining that the transmission rate adjustment strategy is a first transmission rate adjustment strategy, wherein the first target value is the sum of a second target value and a third target value, the second target value is an integral multiple of the number of TCP repeated confirmation messages corresponding to the first transmission rate adjustment strategy, and the third target value is the number of TCP repeated confirmation messages corresponding to a certain value smaller than or equal to a second threshold value; and if the message difference is equal to a fourth target value, determining that the transmission rate adjustment strategy is a first transmission rate adjustment strategy and a second transmission rate adjustment strategy, wherein the fourth target value is the sum of a fifth target value and a third target value, and the fifth target value is the sum of integral multiples of the number of TCP repeated confirmation messages corresponding to the first transmission rate adjustment strategy and integral multiples of the number of TCP repeated confirmation messages corresponding to the second transmission rate adjustment strategy.
Step 306: adjusting the uplink transmission rate of the mobile terminal at least once by using the first transmission rate adjustment strategy and the second transmission rate adjustment strategy; or, the uplink transmission rate of the mobile terminal is adjusted at least once by using the first transmission rate adjustment strategy; and the speed difference value between the first uplink transmission speed actually transmitted by the mobile terminal and the transmission speed actually transmitted by the data forwarding equipment after adjustment is smaller than or equal to a second threshold value.
Specifically, the specific implementation manner of using the first transmission rate adjustment policy at least once to adjust the uplink transmission rate of the mobile terminal includes:
a1: adjusting the uplink transmission rate of the mobile terminal by using a first transmission rate adjustment strategy;
a2: acquiring a third uplink transmission rate actually transmitted by the mobile terminal, wherein the third uplink transmission rate is the uplink transmission rate actually transmitted by the mobile terminal after being adjusted for the first time by using the first transmission rate adjustment strategy;
a3: determining a second rate difference value between the third uplink transmission rate and the actual transmission rate of the data forwarding equipment;
a4: if the second speed difference is greater than the second threshold, repeating steps A1-A3 until the second speed difference is less than or equal to the second threshold.
Specifically, the specific implementation manner of using the first transmission rate adjustment policy and the second transmission rate adjustment policy at least once to adjust the uplink transmission rate of the mobile terminal includes:
b1: adjusting the uplink transmission rate of the mobile terminal by using a first transmission rate adjustment strategy;
b2: acquiring a fourth uplink transmission rate actually transmitted by the mobile terminal, wherein the fourth uplink transmission rate is the uplink transmission rate actually transmitted by the mobile terminal after being adjusted for the first time by using the first transmission rate adjustment strategy;
b3: determining a third rate difference value between the fourth uplink transmission rate and the actual transmission rate of the data forwarding equipment;
b4: if the third rate difference is greater than or equal to the fourth threshold, using the first transmission rate adjustment strategy to adjust a fourth uplink transmission rate actually transmitted by the mobile terminal, wherein a fifth uplink transmission rate actually transmitted by the adjusted mobile terminal is smaller than the fourth uplink transmission rate, the fifth uplink transmission rate is the uplink transmission rate actually transmitted by the mobile terminal which is adjusted for the second time by using the first transmission rate adjustment strategy, and repeating the steps B1-B3 until the third rate difference is smaller than the fourth threshold;
b5: under the condition that the third rate difference is smaller than the fourth threshold, a second transmission rate adjustment strategy is used for adjusting the uplink transmission rate actually transmitted by the mobile terminal, the adjusted sixth uplink transmission rate actually transmitted by the mobile terminal is smaller than the uplink transmission rate actually transmitted by the mobile terminal adjusted in the step B4, and the sixth uplink transmission rate is the uplink transmission rate actually transmitted by the mobile terminal adjusted for the first time by using the second transmission rate adjustment strategy;
b6: determining a fourth rate difference value between the sixth uplink transmission rate and the actual transmission rate of the data forwarding equipment;
b7: if the fourth rate difference is greater than the second threshold, step B5 is repeated until the fourth rate difference is less than the second threshold.
Step 307: determining that the transmission rate adjustment policy is the second transmission rate adjustment policy.
Step 308: adjusting the uplink transmission rate of the mobile terminal at least once by using the second transmission rate adjustment strategy; and the speed difference value between the first uplink transmission speed actually transmitted by the mobile terminal and the transmission speed actually transmitted by the data forwarding equipment after adjustment is smaller than or equal to a second threshold value.
Specifically, the specific implementation manner of using the second transmission rate adjustment policy at least once to adjust the uplink transmission rate of the mobile terminal includes:
s1: adjusting the uplink transmission rate of the mobile terminal by using a second transmission rate adjustment strategy;
s2: acquiring a seventh uplink transmission rate actually transmitted by the mobile terminal, wherein the seventh uplink transmission rate is the uplink transmission rate actually transmitted by the mobile terminal after being adjusted for the first time by using a second transmission rate adjustment strategy;
s3: determining a fifth rate difference value between the seventh uplink transmission rate and the actual transmission rate of the data forwarding equipment;
s4: if the fifth speed difference is greater than the second threshold, repeating the steps S1-S3 until the fifth speed difference is less than the second threshold.
It can be seen that, in the embodiment of the present application, if the number of TCP duplicate acknowledgement packets received by the mobile terminal within a certain period of time exceeds a certain value, it indicates that the actual uplink transmission rate of the mobile terminal is far greater than the actual transmission rate of the data forwarding device, that is, the transmission rate is not matched, in this case, the transmission rate adjustment policy is determined by the packet difference between the number of TCP duplicate acknowledgement packets and the first threshold, and the actual uplink transmission rate of the mobile terminal is adjusted to be close to the actual transmission rate of the data forwarding device by using the transmission rate adjustment policy. Therefore, the speed of the mobile terminal sending data upwards after adjustment is close to the speed of the data transmission equipment transmitting data, the problem that the data transmission equipment and the wireless router discard some data due to the fact that the data transmission equipment cannot process the data sent by the mobile terminal and transmitted by the wireless router in time is solved, and the transmission efficiency of uplink transmission data of the mobile terminal is improved.
Referring to fig. 4, fig. 4 is a schematic flow chart of a transmission rate adjustment method according to an embodiment of the present application, where an execution subject is a mobile terminal, and the method includes:
step 401: and acquiring the quantity of TCP repeated confirmation messages received by the mobile terminal in a target time period.
See the relevant description of step 201, which will not be described here.
Step 402: judging whether the number of the TCP repeated confirmation messages is larger than a first threshold value or not;
if yes, go to step 403.
If not, go to step 401.
See the description related to step 302, which will not be described here.
Step 403: and acquiring a second uplink transmission rate actually transmitted by the mobile terminal, wherein the mobile terminal currently supports a target uplink transmission rate, and the target uplink transmission rate is the maximum transmission rate of uplink transmission allowed by the mobile terminal.
And the second uplink transmission rate is the uplink transmission rate actually transmitted by the mobile terminal when the mobile terminal works at the maximum transmission rate of the uplink transmission rate currently allowed by the mobile terminal.
Step 404: and determining the message difference value between the number of the TCP repeated confirmation messages and the first threshold value.
See the description related to step 303, which will not be described here.
Step 405: and determining the actual transmission rate of the data forwarding equipment according to the second uplink transmission rate and the message difference value.
Specifically, the transmission rate actually transmitted by the data forwarding device is determined according to the second uplink transmission rate, the message difference value and the transmission rate formula.
Wherein, the transmission rate formula is:
Figure BDA0001653630260000091
where V is the transmission rate of actual transmission of the data forwarding device, V1A second uplink transmission rate actually transmitted by the mobile terminal, C is a message difference value, P is a fixed value, and V is2And repeating the transmission rate corresponding to the confirmation messages for the P TCPs.
The fixed value P may be user-defined, or may be user-defined by the mobile terminal, and is not limited herein.
For example, suppose P-5, V24Mbps, the second uplink transmission rate V of the actual transmission of the mobile terminal1For 120Mbps, the mobile terminal determines the message difference value to be 25, and the mobile terminal determines the message difference value according to a transmission rate formula
Figure BDA0001653630260000092
And determining that the transmission rate V actually transmitted by the data forwarding equipment is 100 Mbps.
In some embodiments, determining the transmission rate actually transmitted by the data forwarding device may also be implemented by: under the condition that the number of the TCP repeated confirmation messages is larger than a first threshold value, sending a transmission rate acquisition request to the data forwarding equipment through a wireless router, wherein the transmission rate acquisition request is used for indicating to acquire the actual transmission rate of the data forwarding equipment; and receiving, by the wireless router, the transmission rate actually transmitted by the data forwarding device, where the transmission rate is sent by the data forwarding device.
