Data transmission method and relevant product

TECHNICAL FIELD

0001This disclosure relates to the technical field of communication, and more particularly to a method for data transmission and related products.

BACKGROUND

0002With the popularization of electronic devices (such as mobile phones, tablet computers, etc.), the electronic device can support more and more applications and become more powerful. The electronic device develops towards diversification and individuation, and becomes an essential electronic product in users' lives.

0003At present, during running applications of the electronic device, data packets generated by the application generally need to be sent to other devices. For example, during running a game application of the electronic device, the electronic device needs to send game data to a game server. The electronic device first sends game data packets to an access network device, and then the access network device sends the game data packets to the game server. In the related art, it generally takes a long time for the electronic device to transmit the game data packets to the access network device, which may lead to network latency and cause lag of online gaming, thereby affecting user experience. Similarly, when the electronic device transmits data packets of other applications, instability of the wireless network may also cause the electronic device to take a long time to transmit the data packets. Therefore, how to reduce the time for the electronic device to transmit the data packets is a problem to be solved.

SUMMARY

0026<figref idref="f0002">FIG. 1B</figref> is a schematic flow chart illustrating a method for data transmission according to implementations of the disclosure. The method is applicable to the electronic device illustrated in <figref idref="f0001">FIG. 1A</figref>. The electronic device includes a wireless-fidelity (Wi-Fi) module. The method begins at block 101.

0027At block 101, a first application data packet of a first application of the electronic device is obtained during running the first application.

0028The first application may include any of the following: a game application, a payment application, a chat application, a browser, or the like. In implementations of the disclosure, during running the first application, the first application may generate application data packets. For example, during running of the game application of the electronic device, the game application may generate game application data packets. Alternatively, the payment application may generate payment application data packets.

0029In at least one implementation, the method may further include the following. Determine whether the first application is in a preset application white list. When the first application is in the preset application white list, the first application data packet is tagged according to first user identification (UID) of the first application.

0030In one example, the application white list is set in advance. The application white list may include multiple applications such as a game application(s), a payment application(s), a chat application (s), a browser(s), and so on. The applications in the application white list can be preset by a user or set by default by the system.

0031At block 102, the first application data packet is tagged according to the first UID of the first application, and a first data packet tag of the first application data packet is obtained.

0032In an implementation of the disclosure, each application has corresponding UID. The UID is used for identifying a corresponding application. For example, when the electronic device identifies that the first application is a game application according to the first UID, the first application data packet can be tagged to obtain the first data packet tag for identifying the first application data packet. The first data packet tag may be identified by the Wi-Fi module.

0033At block 103, a target packet loss rate (PLR) of data transmitted by the Wi-Fi module is obtained in response to that the first data packet tag is identified by the Wi-Fi module.

0034When the first application data packet of the first application needs to be transmitted, the Wi-Fi module can identify the first data packet tag. If the Wi-Fi module identifies that an application corresponding to the first data packet tag is in the white list, for example, if the Wi-Fi module identifies that the application corresponding to the first data packet tag is a game application, the target PLR of the data transmitted by the Wi-Fi module is obtained.

0035In at least one implementation, if the first application is a game application, latency time of the game application is obtained during running of the game application. If the latency time is longer than a first preset duration, the method proceeds to obtaining the target PLR of the data transmitted by the Wi-Fi module.

0036In one example, if the latency time is longer than the first preset duration, it can be determined that the game application cannot run smoothly, which may be caused by a relatively long transmission delay of a game application data packet due to the instability of the wireless network, such that the target PLR of the data transmitted by the Wi-Fi module can be obtained.

0037At block 104, when the target PLR is greater than a first preset threshold, first maximum number of retransmissions of the first application data packet is increased to first target number of retransmissions according to the target PLR.

0038The first maximum number of retransmissions refers to maximum number of times the electronic device can retransmit the first application data packet. In the implementations, it can determine whether the target PLR is greater than the first preset threshold. If the target PLR is greater than the first preset threshold, it indicates that the transmission delay of the first application data packet of the first application is relatively long, which may cause the first application to run unsmoothly. Therefore, in order to ensure that the first application data packet can be successfully transmitted, the first maximum number of retransmissions of the first application data packet can be increased according to the target PLR, thereby improving a success rate of transmitting the first application data packet by the electronic device.

0039In at least one implementation, the first maximum number of retransmissions of the first application data packet is increased to the first target number of retransmissions according to the target PLR as follows (i.e., the operations at block 104 include operations at block 41 and 42).

0040At block 41, the first target number of retransmissions corresponding to the target PLR is determined according to a preset corresponding relationship between PLRs and first maximum number of retransmissions.

0041At block 42, the first maximum number of retransmissions of the first application data packet is increased to the first target number of retransmissions.

0042In one example, the corresponding relationship between the PLRs and the first maximum number of retransmissions can be preset. For example, the following table illustrates a corresponding relationship between the packet error rates (PERs) and the first maximum number of retransmissions. <tables id="tabl0001" num="0001"><table frame="all"><tgroup cols="2"><colspec colnum="1" colname="col1" colwidth="37mm" /><colspec colnum="2" colname="col2" colwidth="66mm" /><thead><row><entry align="center" valign="top">Packet loss rate (PER)</entry><entry align="center" valign="top">First maximum number of retransmissions</entry></row></thead><tbody><row><entry align="center">PER > T1</entry><entry align="center">U1</entry></row><row><entry align="center">T1>PER > T2</entry><entry align="center">U2</entry></row><row><entry align="center">T2>PER > T3</entry><entry align="center">U3</entry></row></tbody></tgroup></table></tables> In the table, T1, T2, and T3 represent PLRs, which can be adjusted according to measured data, and U1, U2, and U3 represent number of retransmissions, which can be determined according to a memory size of a chip of the electronic device.

0043In one example, the electronic device can determine the first target number of retransmissions corresponding to the target PLR according to the above corresponding relationship, and then increase the first maximum number of retransmissions of the first application data packet to the first target number of retransmissions. For example, if the first maximum number of retransmissions of the first application data packet transmitted by the Wi-Fi module is initially determined to be 10 times, after the first target number of retransmissions is determined to be 15 times, the first maximum number of retransmissions may be increased to 15 times.

0044At block 105, the first application data packet is transmitted according to the first target number of retransmissions.

0045According to the method provided herein, the electronic device can transmit the first application data packet through the Wi-Fi module. In one example, for different first applications, the Wi-Fi module can transmit first application data packets to different external devices. For example, if the first application is a game application, the electronic device may send a game application data packet to an access network device, such that the access network device can send the game application data packet to a core network device, and then the core network device can send the game application data packet to a server. Therefore, data transmission between the electronic device and the server can be realized. For another example, if the electronic device is a payment application, the electronic device can send a payment application data packet to the server.

0046In one example, the first application is a game application, and the first application data packet is transmitted according to the first target number of retransmissions as follows (i.e., the operations at block 105 include operations at block 51 and 52).

0047At block 51, the first application data packet is transmitted to the access network device.

0048At block 52, when no first acknowledgement message indicative of successful transmission of the first application data packet is received within a first preset time period, the first application data packet is retransmitted to the access network device until receiving a first acknowledgement message, where number of times of retransmitting the first application data packet to the access network device does not exceed the first target number of retransmissions.

0049According to implementations, if the first application is the game application, the electronic device may transmit the game application data packet of the game application. <figref idref="f0003">FIG. 1C</figref> illustrates a network architecture in which the electronic device transmits game application data packets according to implementations of the disclosure. The electronic device can run a large-scale terminal game, such as a competitive played game. The electronic device can send the game application data packet to the access network device, such that the access network device can send the game application data packet to the core network device and then the core network device can send the game application data packet to the server. If the wireless network is not stable enough, during running of the game application, a game lag or slow in response may be caused due to a long transmission delay of the game application data packet, thereby affecting the game experience. Therefore, before the electronic device sends the first application data packet to the access network device, the first maximum number of retransmissions can be increased.

0050When the electronic device receives the first acknowledgement message indicative of successful transmission of the first application data packet, it may be determined that the first application data packet is successfully transmitted. If the first application does not receive the first acknowledgement message, the first application data packet can be retransmitted to the access network device until the first acknowledgement message is received. Furthermore, if the electronic device still does not receive the first acknowledgement message after the number of times of retransmitting the first application data packet to the access network device has reached the first target number of retransmissions, the electronic device does not continue to retransmit first application data packet, and determines that transmission of the first application data packet fails.

0051In at least one implementation, if a size (amount of data) of the first application data packet is greater than a second preset threshold, the first application data packet is retransmitted to the access network device as follows.

0052At A1, the first application data packet is divided into multiple application data sub-packets.

0053At A2, the multiple application data sub-packets are transmitted to the access network device according to a preset time interval.

0054When the electronic device retransmits the first application data packet, if the size of the first application packet is relatively large, the first application data packet may be divided into multiple application data sub-packets, and then the multiple application data sub-packets are sequentially retransmitted. In one example, the first data packet tag corresponding to the first application data packet can be added to a first application data sub-packet, such that messages indicative of successful transmission of the multiple application data sub-packets can be identified according to the first data packet tag.

0055In one example, the electronic device runs a second application while running the first application. The method further includes the following.

0056At B1, a second application data packet of the second application is tagged according to second UID of the second application, and a second data packet tag of the second application data packet is obtained.

0057At B2, when the second data packet tag is identified by the Wi-Fi module, second maximum number of retransmissions of the second application data packet transmitted by the Wi-Fi module is decreased to second target number of retransmissions according to the target PLR.

0058At B3, the second application data packet is transmitted according to the second target number of retransmissions.

0059In one example, the second application may include any of the following: a read application, a video playing application, an audio playing application, an application for synchronous backup, or other applications for transferring large files. The second maximum number of retransmissions refers to maximum number of times the Wi-Fi module can retransmit the second application data packet. In order to ensure that the first application data packet of the first application can be successfully transmitted, the second maximum number of retransmissions of the second application data packet transmitted by the Wi-Fi module can be reduced. For example, if the second maximum number of retransmissions of the second application data packet transmitted by the Wi-Fi module is initially determined to be 10 times, the second target number of retransmissions corresponding to the target PLR can be determined according to the preset corresponding relationship between PLRs and second maximum number of retransmissions, for example, the second target number of retransmissions is determined to be 6 times, and thus the second maximum number of retransmissions can be reduced from 10 times to 6 times. That is, the maximum number of retransmissions is reduced when the Wi-Fi module transmits the second application data packet. When number of times the Wi-Fi module retransmits the second application data packet has reached the second target number of retransmissions, the retransmission ends, such that more network resources can be allocated to the first application data packet for transmitting the first application data packet, thereby reducing the transmission delay of the first application data packet.

0060In at least one implementation, it can be further determined whether the second application is in a preset application black list; if yes, the method proceeds to tagging the second application data packet of the second application according to the second UID of the second application.

0061In one example, the application black list can be set in advance. Applications in the application black list may include a read application, a video playing application, an audio playing application, an application for synchronous backup, or other applications for transferring large files. The applications in the application black list can be preset by a user or set by default by the system.

0062In at least one implementation, the following can be conducted after the first application data packet is transmitted according to the first target number of retransmissions.

0063A total transmission delay of the first application data packet is obtained.

0064The second application is closed on condition that the total transmission delay is longer than a second preset duration.

0065In the implementations, when the total transmission delay of the first application data packet is longer than the second preset duration, it indicates that the first application runs unsmoothly, which may affect user experience. Therefore, the second application can be closed, and the transmission of the second application data packet may be stopped, such that a success rate of the transmission of the first application data packet may be improved and the transmission delay of the first application data packet can be reduced, thereby ensuring smooth running of the first application.

0066According to the method for data transmission provided herein, the first application data packet of the first application is obtained during running the first application. The first application data packet is tagged according to the first UID of the first application, and the first data packet tag of the first application data packet is obtained. The target PLR of the data transmitted by the Wi-Fi module is obtained in response to that the first data packet tag is identified by the Wi-Fi module. When the target PLR is greater than the first preset threshold, the first maximum number of retransmissions of the first application data packet is increased to the first target number of retransmissions according to the target PLR. The first application data packet is transmitted according to the first target number of retransmissions. In this way, it is possible to increase the success rate that the electronic device transmits the first application data packet by increasing the maximum number of retransmissions of the first application data packet transmitted by the Wi-Fi module, and thus there is no need to trigger an upper layer retransmission mechanism, thereby greatly reducing the transmission delay of the first application data packet and avoiding affecting the running of the first application due to the instability of the wireless network.

0067Similar to the implementations illustrated in <figref idref="f0002">FIG. 1B</figref>, <figref idref="f0004">FIG. 2</figref> is a schematic flow chart illustrating a method for data transmission according to other implementations of the disclosure. The method is applicable to an electronic device including a Wi-Fi module. The method begins at block 201.

0068At block 201, a first application data packet of a first application of the electronic device is obtained during running the first application.

0069At block 202, the first application data packet is tagged according to first UID of the first application, and a first data packet tag of the first application data packet is obtained.

0070At block 203, a target PLR of data transmitted by the Wi-Fi module is obtained when the first data packet tag is identified by the Wi-Fi module.

0071At block 204, when the PLR is greater than a first preset threshold, first maximum number of retransmissions of the first application data packet is increased to first target number of retransmissions according to the target PLR.

0072At block 205, the first application data packet is transmitted according to the first target number of retransmissions.

0073At block 206, when the electronic device runs a second application while running the first application, a second application data packet of the second application is tagged according to second UID of the second application, and a second data packet tag of the second application data packet is obtained.

0074At block 207, when the second data packet tag is identified by the Wi-Fi module, second maximum number of retransmissions of the second application data packet transmitted by the Wi-Fi module is decreased to second target number of retransmissions according to the target PLR.

0075At block 208, the second application data packet is transmitted according to the second target number of retransmissions.

0076For the detailed description of the above operations at block 201 to 208, reference may be made to the corresponding description of the method for data transmission described in <figref idref="f0002">FIG. 1B</figref>, which will not be repeated herein.

0077As can be seen, in the method for data transmission, during running the first application, the first application data packet of the first application is obtained. The first application data packet is tagged according to the first UID of the first application, and the first data packet tag of the first application data packet is obtained. The target PLR of the data transmitted by the Wi-Fi module is obtained in response to that the first data packet tag is identified by the Wi-Fi module. When the target PLR is greater than the first preset threshold, the first maximum number of retransmissions of the first application data packet is increased to the first target number of retransmissions according to the target PLR, and the first application data packet is transmitted according to the first target number of retransmissions. In addition, the second maximum number of retransmissions of the second application data packet transmitted by the Wi-Fi module is decreased to the second target number of retransmissions according to the target PLR, and the second application data packet is transmitted according to the second target number of retransmissions. In this way, it is possible to increase the success rate that the electronic device transmits the first application data packet by increasing the first maximum number of retransmissions of the first application data packet transmitted by the Wi-Fi module and decreasing the second maximum number of retransmissions of the second application data packet transmitted by the Wi-Fi module, and thus there is no need to trigger the upper layer retransmission mechanism, thereby greatly reducing transmission delay of the first application data packet and avoiding affecting the running of the first application due to the instability of the wireless network.

0078Similar to the foregoing method, <figref idref="f0005">FIG. 3</figref> is a schematic flow chart illustrating a method for data transmission according to other implementations of the disclosure. The method is applicable to the electronic device illustrated in <figref idref="f0001">FIG. 1A</figref>, and the electronic device includes a Wi-Fi module. The method begins at block 301.

0079At block 301, a first application data packet of a first application of the electronic device is obtained during running the first application.

0080At block 302, determine whether the first application is in a preset application white list, and when the first application is in the preset application white list, the first application data packet is tagged according to first UID of the first application, and a first data packet tag of the first application data packet is obtained.

0081At block 303, a target PLR of data transmitted by the Wi-Fi module is obtained when the first data packet tag is identified by the Wi-Fi module.

0082At block 304, when the target PLR is greater than a first preset threshold, the first target number of retransmissions corresponding to the target PLR is determined according to a preset corresponding relationship between PLRs and first maximum number of retransmissions.

0083At block 305, the first maximum number of retransmissions of the first application data packet is increased to first target number of retransmissions.

0084At block 306, the first application data packet is transmitted according to the first target number of retransmissions.

0085At block 307, when the electronic device runs a second application while running the first application, determine whether the second application is in a preset application black list, and when the second application is in the preset application black list, a second application data packet of the second application is tagged according to second UID of the second application, and a second data packet tag of the second application data packet is obtained.

0086At block 308, when the second data packet tag is identified by the Wi-Fi module, second maximum number of retransmissions of the second application data packet transmitted by the Wi-Fi module is decreased to second target number of retransmissions according to the target PLR.

0087At block 309, the second application data packet is transmitted according to the second target number of retransmissions.

0088For the detailed description of the above operations at block 301 to 309, reference may be made to the corresponding description of the method for data transmission described in <figref idref="f0002">FIG. 1B</figref>, which will not be repeated herein.

0089As can be seen, in the method for data transmission, during running the first application, the first application data packet of the first application is obtained. Determine whether the first application is in the preset application white list; if the first application is in the preset application white list, the first application data packet is tagged according to the first UID of the first application, and the first data packet tag of the first application data packet is obtained. The target PLR of the data transmitted by the Wi-Fi module is obtained when the first data packet tag is identified by the Wi-Fi module. When the target PLR is greater than the first preset threshold, the first maximum number of retransmissions of the first application data packet is increased to the first target number of retransmissions according to the target PLR, and the first application data packet is transmitted according to the first target number of retransmissions. In addition, the second maximum number of retransmissions of the second application data packet transmitted by the Wi-Fi module is decreased to the second target number of retransmissions according to the target PLR, and the second application data packet is transmitted according to the second target number of retransmissions. In this way, it is possible to increase the success rate that the electronic device transmits the first application data packet by increasing the maximum number of retransmissions of the first application data packet transmitted by the Wi-Fi module and decreasing the maximum number of retransmissions of the second application data packet transmitted by the Wi-Fi module, and thus there is no need to trigger the upper layer retransmission mechanism, thereby greatly reducing transmission delay of the first application data packet and avoiding affecting the running of the first application due to the instability of the wireless network.
