Description
Technical Field
The invention relates to the technical field of mobile terminals, in particular to a data sending method and a mobile terminal.
Background
At present, smart phones are enjoyed by more and more users. However, compared with a common mobile phone, the smart phone consumes more power. Therefore, power saving of smart phones is a problem in the industry. At present, making a smart phone sleep is a better solution for saving power of the smart phone. Of course, so is the WiFi connection for the smartphone.
At present, all WiFi sleep modes of smart phones in the market are mainly that when it is detected that there is no data interaction between the smart phone and the wireless access point, the wireless module of the phone enters a sleep Mode, that is, the flag PS (Power Save Mode) of the Power consumption management module (PSM) of the smart phone is set to 1, and until the smart phone has a new data request, the flag PS of the PSM is set to 0, so that the wireless module is awakened and enters a normal working state. When the smart phone is awakened, the smart phone needs to perform Channel Clear Assignment (CCA) again, and if the Channel is busy, the mobile terminal needs to back off for a period of time and then waits for the Channel to be Clear, and then sends data. However, when the smart phone is in a weak signal network environment, the data packet for channel idle detection needs to be sent at a low rate based on low order modulation, which reduces the sending rate of data sent by the mobile terminal in the weak signal network environment, thereby reducing the WiFi connection performance.

Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
In order to better understand a data transmission method and a mobile terminal disclosed in the embodiments of the present invention, the following describes the embodiments of the present invention in detail.
Referring to fig. 1, fig. 1 is a schematic flow chart of a data transmission method according to an embodiment of the present invention, and as shown in fig. 1, the data transmission method according to the embodiment of the present invention includes the following steps:
s101, the mobile terminal detects whether the state parameter of the wireless network currently accessed by the mobile terminal meets a preset condition.
Here, the mobile terminal may detect whether the RSSI value is less than or equal to a preset signal strength threshold by detecting whether the RSSI value is less than or equal to the preset signal strength threshold, and when the RSSI value is less than or equal to the preset signal strength threshold, detect that the state parameter of the wireless network currently accessed by the mobile terminal satisfies the preset condition.
Here, the preset signal strength threshold is generally-75 dbm, that is, when the mobile terminal detects that the mobile terminal receives a wireless signal strength value RSSI less than or equal to-75 dbm, it can be considered that the wireless network signal currently accessed by the mobile terminal is weak. For example, when the mobile terminal accesses the wireless access point in the public place, only 1 to 2 wireless signals are displayed in the mobile terminal, and the RSSI value of the wireless signal strength received by the mobile terminal is generally below-75 dbm.
Or, the mobile terminal may further detect that the state parameter of the wireless network to which the mobile terminal is currently accessed meets the preset condition when detecting that the retransmission rate of the uplink data of the mobile terminal is greater than or equal to a first preset threshold by detecting whether the retransmission rate of the uplink data of the mobile terminal is greater than or equal to the first preset threshold.
Or, the mobile terminal may further detect that the state parameter of the wireless network to which the mobile terminal is currently accessed meets the preset condition when detecting that the packet loss rate of the downlink data of the mobile terminal is greater than or equal to a second preset threshold by detecting whether the packet loss rate of the downlink data of the mobile terminal is greater than or equal to the second preset threshold.
When the mobile terminal detects that the state parameter of the wireless network currently accessed by the mobile terminal does not meet the preset condition and detects that no data sending request aiming at the application exists in the preset time period, the mobile terminal controls the wireless module of the mobile terminal to enter a sleep state so as to reduce the power consumption of the mobile terminal and prolong the endurance time of the mobile terminal.
S102, when detecting that the state parameter of the wireless network currently accessed by the mobile terminal meets the preset condition, the mobile terminal detects whether a data sending request for an application exists in a first preset time period, wherein the data sending request is used for requesting to send application data to a wireless access point of the wireless network.
Here, the data sending request for the application may be a file obtaining request carrying a picture identifier, a video identifier, a music identifier, a document identifier, or the like, or may be an application updating request carrying an application identifier for updating a version of the currently installed application, and the like, and the embodiment of the present invention is not limited.
S103, when detecting that no data sending request exists in the first preset time period, the mobile terminal sends a null data frame to the wireless access point, wherein the null data frame is used for indicating that the mobile terminal is in an awakening state.
Here, null data frame (null data) is a special data frame, and is low in consumption, for always maintaining an effective connection with the wireless access point.
S104, when detecting a data transmission request aiming at a target application, the mobile terminal transmits application data corresponding to the data transmission request aiming at the target application to the wireless access point.
It can be seen that, compared with the scheme in the prior art in which the mobile terminal controls the mobile terminal to enter the sleep state when detecting that there is no data transmission request for an application within a first preset time period, the data transmission method provided in the embodiment of the present invention detects whether there is a data transmission request for an application within a first preset time period when the mobile terminal detects that a state parameter of a currently accessed wireless network satisfies a preset condition, the data transmission request is for requesting transmission of application data to a wireless access point of the wireless network, and then, upon detecting that there is no data transmission request within the first preset time period, transmitting a null data frame to the wireless access point to indicate that the mobile terminal is in an awake state, and finally, when a data transmission request for a target application is detected, transmitting application data corresponding to the data transmission request for the target application to a wireless access point. Therefore, when the mobile terminal detects that no data sending request exists in the first preset time period, the mobile terminal sends the empty data frame to the wireless access point to maintain the awakening state of the mobile terminal, so that the problem that when the mobile terminal is in a weak signal network environment in the existing scheme, the data sending rate is reduced due to the fact that channel detection needs to be carried out again when the mobile terminal is switched from a sleep state to the awakening state is avoided, the sending rate of the data sent by the mobile terminal is favorably improved when the weak signal network environment is improved, and the WiFi connection performance of the mobile terminal is favorably improved when the weak signal network environment is improved.
Referring to fig. 2, fig. 2 is a schematic flow chart of another data transmission method according to an embodiment of the present invention, which is consistent with the embodiment shown in fig. 1. As shown in fig. 2, the data transmission method in the embodiment of the present invention includes the following steps:
s201, the mobile terminal detects whether the RSSI value of the received wireless signal intensity of the mobile terminal is smaller than or equal to a preset signal intensity threshold value.
After detecting whether the mobile terminal received wireless signal strength value RSSI is less than or equal to a preset signal strength threshold value, the mobile terminal performs steps S202 to S204 when detecting that the mobile terminal received wireless signal strength value RSSI is less than or equal to the preset signal strength threshold value; when detecting that the RSSI value is greater than the threshold, steps S205 to S206 are performed.
S202, when detecting that the RSSI (received radio signal strength value) of the mobile terminal is less than or equal to the preset signal strength threshold value, the mobile terminal detects whether a data transmission request for an application exists in a first preset time period, wherein the data transmission request is used for requesting to transmit application data to a radio access point of the wireless network.
S203, when detecting that no data sending request exists in the first preset time period, the mobile terminal sends a null data frame to the wireless access point, wherein the null data frame is used for indicating that the mobile terminal is in an awakening state.
S204, when detecting a data transmission request aiming at the target application, the mobile terminal transmits application data corresponding to the data transmission request aiming at the target application to the wireless access point.
S205, when detecting that the RSSI is greater than the preset signal strength threshold value, the mobile terminal detects whether a data transmission request for an application exists in a first preset time period.
S206, when detecting that no data transmission request aiming at the application exists in the preset time period, the mobile terminal controls the wireless module of the mobile terminal to enter a sleep state.
Here, the wireless module of the mobile terminal enters a sleep state, that is, the flag PS (power save) of the power consumption management module (PSM) of the mobile terminal is set to 1 until the flag PS of the PSM is set to 0 when a new data transmission request for a target application is detected, so that the wireless module is awakened, enters a normal operation state, and transmits application data corresponding to the data transmission request for the target application to the wireless access point.
Here, after the wireless module of the mobile terminal enters the sleep state, when the mobile terminal detects a data transmission request for a target application, the mobile terminal transmits application data corresponding to the data transmission request for the target application to the wireless access point, that is, step S204 is executed.
It can be seen that, compared with the scheme in the prior art in which the mobile terminal controls the mobile terminal to enter the sleep state when detecting that there is no data transmission request for an application within a first preset time period, the data transmission method provided in the embodiment of the present invention detects whether there is a data transmission request for an application within a first preset time period when the mobile terminal detects that a state parameter of a currently accessed wireless network satisfies a preset condition, the data transmission request is for requesting transmission of application data to a wireless access point of the wireless network, and then, upon detecting that there is no data transmission request within the first preset time period, transmitting a null data frame to the wireless access point to indicate that the mobile terminal is in an awake state, and finally, when a data transmission request for a target application is detected, transmitting application data corresponding to the data transmission request for the target application to a wireless access point. Therefore, when the mobile terminal detects that no data sending request exists in the first preset time period, the mobile terminal sends the empty data frame to the wireless access point to maintain the awakening state of the mobile terminal, so that the problem that when the mobile terminal is in a weak signal network environment in the existing scheme, the data sending rate is reduced due to the fact that channel detection needs to be carried out again when the mobile terminal is switched from a sleep state to the awakening state is avoided, the sending rate of the data sent by the mobile terminal is favorably improved when the weak signal network environment is improved, and the WiFi connection performance of the mobile terminal is favorably improved when the weak signal network environment is improved.

As shown in fig. 3, the data transmission method in the embodiment of the present invention includes the following steps:
s301, the mobile terminal detects whether the retransmission rate of the uplink data of the mobile terminal is greater than or equal to a first preset threshold value.
After the mobile terminal detects whether the retransmission rate of the uplink data of the mobile terminal is greater than or equal to a first preset threshold, the mobile terminal executes steps S302 to S304 when detecting that the retransmission rate of the uplink data of the mobile terminal is greater than or equal to the first preset threshold; the mobile terminal executes steps S305 to S306 when detecting that the retransmission rate of the uplink data of the mobile terminal is smaller than the first preset threshold.
S302, when detecting that the retransmission rate of the uplink data of the mobile terminal is greater than or equal to the first preset threshold value, the mobile terminal detects whether a data sending request for an application exists in a first preset time period, wherein the data sending request is used for requesting to send application data to a wireless access point of the wireless network.
And S303, when detecting that no data transmission request exists in the first preset time period, the mobile terminal transmits a null data frame to the wireless access point, wherein the null data frame is used for indicating that the mobile terminal is in an awakening state.
S304, when detecting the data transmission request aiming at the target application, the mobile terminal transmits the application data corresponding to the data transmission request aiming at the target application to the wireless access point.
S305, when detecting that the retransmission rate of the uplink data of the mobile terminal is smaller than the first preset threshold value, the mobile terminal detects whether a data sending request for an application exists in a first preset time period.
S306, when detecting that no data transmission request aiming at the application exists in the preset time period, the mobile terminal controls the wireless module of the mobile terminal to enter a sleep state.
Here, after the wireless module of the mobile terminal enters the sleep state, when the mobile terminal detects a data transmission request for a target application, the mobile terminal transmits application data corresponding to the data transmission request for the target application to the wireless access point, that is, step S304 is executed.
It can be seen that, compared with the scheme in the prior art in which the mobile terminal controls the mobile terminal to enter the sleep state when detecting that there is no data transmission request for an application within a first preset time period, the data transmission method provided in the embodiment of the present invention detects whether there is a data transmission request for an application within a first preset time period when the mobile terminal detects that a state parameter of a currently accessed wireless network satisfies a preset condition, the data transmission request is for requesting transmission of application data to a wireless access point of the wireless network, and then, upon detecting that there is no data transmission request within the first preset time period, transmitting a null data frame to the wireless access point to indicate that the mobile terminal is in an awake state, and finally, when a data transmission request for a target application is detected, transmitting application data corresponding to the data transmission request for the target application to a wireless access point. Therefore, when the mobile terminal detects that no data sending request exists in the first preset time period, the mobile terminal sends the empty data frame to the wireless access point to maintain the awakening state of the mobile terminal, so that the problem that when the mobile terminal is in a weak signal network environment in the existing scheme, the data sending rate is reduced due to the fact that channel detection needs to be carried out again when the mobile terminal is switched from a sleep state to the awakening state is avoided, the sending rate of the data sent by the mobile terminal is favorably improved when the weak signal network environment is improved, and the WiFi connection performance of the mobile terminal is favorably improved when the weak signal network environment is improved.
Referring to fig. 4, in accordance with the embodiment shown in fig. 1, fig. 4 is a schematic flow chart of another data transmission method according to an embodiment of the present invention. As shown in fig. 4, the data transmission method in the embodiment of the present invention includes the following steps:
s401, the mobile terminal detects whether the packet loss rate of the downlink data of the mobile terminal is greater than or equal to a second preset threshold value.
After the mobile terminal detects whether the packet loss rate of the downlink data of the mobile terminal is greater than or equal to a second preset threshold, the mobile terminal executes steps S402 to S404 when detecting that the packet loss rate of the downlink data of the mobile terminal is greater than or equal to the second preset threshold; and the mobile terminal executes the steps S405 to S406 when detecting that the packet loss rate of the downlink data of the mobile terminal is smaller than the second preset threshold.
