Description

Background Art

[0002] Multi-access technology allows terminals to access Wi-Fi (Wireless Fidelity) and cellular links at the same time, achieving seamless switching, traffic diversion and convergence between Wi-Fi and cellular, thereby achieving a smooth user experience, greater throughput and better robustness. The more commonly used traffic diversion mode is the primary-backup mode, which means setting one of the Wi-Fi and cellular links as the primary link and the other as the backup link. When the primary link is unavailable, the traffic is directed to the backup link.

[0003] However, in actual applications, when the signal of the main link is very weak but still connectable, a large amount of data has been lost and retransmitted, and the rate is very slow. However, the terminal will not switch to the backup link when transmitting data at this time, and will still use the main link to transmit data, resulting in very low data transmission efficiency.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0043] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0044] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0045] The specific implementation of the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

[0046] Figure 1 FIG. 1 shows a schematic diagram of a terminal data transmission system architecture that can be applied in the embodiments of the present disclosure. Figure 1 As shown, the system architecture may include: a terminal 10 and a data receiver 20. Two devices in the system are connected via a network, which may be a wireless network.

[0047] Optionally, the wireless network described above uses standard communication technologies and / or protocols. The network is typically the Internet, but may also be any network, including but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile or wireless network, a dedicated network, or any combination of a virtual private network). In some embodiments, technologies and / or formats including Hyper Text Mark-up Language (HTML), Extensible Markup Language (XML), etc. are used to represent data exchanged over the network. In addition, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPSec) may be used to encrypt all or some links. In other embodiments, customized and / or dedicated data communication technologies may also be used to replace or supplement the above data communication technologies.

[0048] In some embodiments of the present disclosure, the terminal 10 transmits data to the data receiver 20 via Wi-Fi or a cellular network. The data receiver 20 may be a server or a network element device in a communication network, which is not limited in the embodiments of the present disclosure. The terminal 10 uses the data splitting transmission technology in the primary and backup mode for data transmission, that is, a transmission link with a higher priority level is selected. For example, when the user wants to use Wi-Fi as much as possible, Wi-Fi is set as the primary transmission link and the cellular network is set as the backup transmission link. When transmitting data, the terminal gives priority to transmitting through the primary transmission link.

[0049] In some embodiments of the present disclosure, the terminal 10 monitors the quality indicator information of the data transmitted by the terminal through the main transmission link within the first preset time period; when the quality indicator information of the data transmitted by the terminal through the main transmission link within the first preset time period meets the preset indicator threshold condition, the terminal is controlled to transmit data through the backup transmission link. It should be noted that the terminal 10 can start the first timer when transmitting data through the main transmission link, and the terminal 10 monitors the packet loss rate and retransmission times of the main transmission link at the MAC (Media Access Control, Media Access Control) sublayer of the main transmission link, wherein the packet loss rate can be the average packet loss rate from the start time of the first timer to the current monitoring time. When it is monitored that the average packet loss rate exceeds the predetermined packet loss rate threshold and / or the number of retransmissions exceeds the predetermined retransmission number threshold, it proves that the data transmission quality of the main transmission link is poor, and the terminal is controlled to transmit data through the backup transmission link. If the quality indicator information does not meet the preset indicator threshold condition until the first timer ends, it proves that the data transmission quality of the main transmission link is better, and data can continue to be transmitted on the main transmission link, then the first timer is resumed and restarted, and the quality indicator information of the data transmitted by the terminal through the main transmission link is continuously monitored.

[0050] like Figure 1 As shown, it also includes a method for terminal data transmission, including:

[0051] S102, the terminal 10 monitors quality indicator information of data transmitted by the terminal through the main transmission link within a first preset time period;

[0052] S104, when the quality indicator information of the data transmitted by the terminal through the main transmission link within the first preset time period meets the preset indicator threshold condition, control the terminal 10 to transmit data through the backup transmission link;

[0053] S106, the terminal 10 notifies the data receiving party 20 of the change of the transmission link through signaling.

[0054] Those skilled in the art will know that Figure 1The number of terminals 10 and data receivers 20 in the figure is only for illustration, and any number of terminals and data receivers may be provided according to actual needs. The embodiments of the present disclosure are not limited to this.

[0055] Under the above system architecture, a terminal data transmission method is provided in an embodiment of the present disclosure. In some embodiments, the terminal data transmission method provided in an embodiment of the present disclosure can be implemented by the terminal or by the interaction between the terminal and the data receiver.

[0056] like Figure 2 As shown, a terminal data transmission method provided in an embodiment of the present disclosure includes the steps of:

[0057] S202: Monitor quality indicator information of data transmitted by a terminal through a first transmission link within a first preset time period.

[0058] It should be noted that the first preset time period may be a preset duration, and the appropriate duration may be determined according to the actual transmission process, for example, it may be set to 2 seconds, 5 seconds or 10 seconds, etc. It may also be the duration between the preset start time and each monitoring time, and the monitoring may be performed at preset intervals, for example, every 0.05 seconds, to monitor the quality indicator information of the transmission data in the time period between the preset start time and each monitoring time.

[0059] S204: When the quality indicator information of data transmitted by the terminal through the first transmission link within the first preset time period meets the preset indicator threshold condition, control the terminal to transmit data through the second transmission link.

[0060] It can be seen from the above steps that the terminal data transmission method provided in the embodiment of the present disclosure monitors the quality index information of the data transmitted by the terminal through the first transmission link within the first preset time period, and when the quality index information meets the preset index threshold condition, controls the terminal to transmit through the second transmission link. This avoids the problem of low data transmission quality and low transmission efficiency caused by the terminal still using the first transmission link when the signal of the first transmission link in the master-slave mode is very weak but still connectable, and controls the terminal to switch to a new transmission link to transmit data, thereby improving data transmission efficiency and transmission quality.

[0061] It should be noted that in the embodiments of the present disclosure, the first transmission link may be the main transmission link, and correspondingly, the second transmission link may be the backup transmission link; or the first transmission link may be the backup transmission link, and the second transmission link may be the main transmission link. That is, when the link status is not good during transmission on the backup transmission link, the main transmission link may be switched back for transmission.

[0062] In some embodiments of the present disclosure, the quality indicator information includes at least one of the following: number of retransmissions and packet loss rate. The preset indicator threshold condition means that the number of retransmissions exceeds a preset retransmission number threshold and / or the packet loss rate exceeds a preset packet loss rate threshold.

[0063] In some embodiments of the present disclosure, when the first transmission link is the main transmission link and the second transmission link is the backup transmission link, it is necessary to switch to the main transmission link again when the backup transmission data link is in a poor state due to transmission on the backup transmission link for a period of time. Multiple switching may even occur. However, frequent switching in a short period of time will bring about a ping-pong effect, which may occupy more system resources of the terminal and cause a decrease in network performance. In order to avoid the ping-pong effect, after the control terminal transmits data through the second transmission link, such as Figure 3 As shown, the terminal data transmission method also includes the following steps:

[0064] S302, monitoring quality indicator information of data transmitted by the terminal through the second transmission link within a second preset time period;

[0065] S304, when the quality indicator information of the data transmitted by the terminal through the second transmission link within the second preset time period meets the preset indicator threshold condition, monitoring the duration from the moment when the terminal starts to transmit data through the second transmission link to the current moment;

[0066] It should be noted that the time when the terminal starts transmitting data through the second transmission link refers to the time when the first transmission link is switched to the second transmission link for the first time, and the cumulative number of link switching times of the terminal is 1 at this time.

[0067] S306, when the duration does not exceed the third preset duration, counting the cumulative number of link switching times of the terminal;

[0068] It should be noted that the cumulative number of link switching times of the terminal is counted starting from the time when the cumulative number of link switching times of the terminal is reset to zero, wherein the timing when the cumulative number of link switching times of the terminal is reset to zero may be the first time that the terminal transmits data through the first transmission link, or it may be the subsequent switch back to the first transmission link and restart a new round.

[0069] S308, if the cumulative link switching number of the terminal does not exceed the preset switching number, control the terminal to transmit data through the first transmission link, and increase the cumulative link switching number of the terminal;

[0070] S310, re-monitor the quality indicator information of data transmitted by the terminal through the first transmission link within the first preset time period, and when the quality indicator information of data transmitted by the terminal through the first transmission link within the first preset time period meets the preset indicator threshold condition, control the terminal to transmit data through the second transmission link; re-monitor the quality indicator information of data transmitted by the terminal through the second transmission link within the second preset time period; when the quality indicator information of data transmitted by the terminal through the second transmission link within the second preset time period meets the preset indicator threshold condition, control the terminal to transmit data through the first transmission link; switch multiple times, and re-count the cumulative number of link switching times of the terminal, until the cumulative number of link switching times of the terminal exceeds the preset number of switching times or the duration exceeds the third preset duration.

[0071] It should be noted that when the cumulative link switching times of the terminal does not exceed the preset switching times, the first transmission link can be switched back. At this time, the transmission quality of the first transmission link may still be poor, and the second transmission link can be switched again. The transmission quality of the second transmission link is poor, that is, when the quality index information of the terminal transmitting data through the second transmission link in the second preset time period meets the preset index threshold condition, it can be switched to the first transmission link. Based on the above judgment conditions, the transmission link can be switched back and forth, and the cumulative link switching times of the terminal are increased by one each time the terminal is switched, until the cumulative link switching times of the terminal exceed the preset switching times or the duration exceeds the third preset duration. However, if after switching back to the first transmission link, the quality index information of the terminal transmitting data through the first transmission link in the first preset time period has not met the preset index threshold condition, then continue to monitor until the duration exceeds the third preset duration, and still control the terminal to transmit data through the first transmission link, but clear the cumulative link switching times of the terminal, and set the moment when the duration exceeds the third preset duration as the start time of the next round, and repeat the steps starting from S202.

[0072] When the duration does not exceed the third preset duration, but the cumulative link switching times of the terminal have exceeded the preset switching times, the link switching times in a short period of time are too many and too frequent. In order to avoid the ping-pong effect, in some embodiments of the present disclosure, a terminal data transmission method is provided, after counting the cumulative link switching times of the terminal, such as Figure 4 As shown, the following steps are also included:

[0073] S402: If the accumulated link switching times of the terminal exceed the preset switching times, control the terminal to transmit data through the existing transmission link for a fourth preset time period.

[0074] It should be noted that when it is determined that the cumulative link switching times of the terminal exceeds the preset switching times, the transmission link currently in use is determined to be either the first transmission link or the second transmission link as the existing transmission link. In the process of controlling the terminal to transmit data through the existing transmission link for a fourth preset duration, it is no longer necessary to determine whether the duration exceeds the third preset duration. After the fourth preset duration, the cumulative link switching times of the terminal are set to zero. If the duration has not exceeded the third preset duration, it is re-determined whether the cumulative link switching times of the terminal exceeds the preset switching times, and the above S308, S310 and S402 are repeated.

[0075] In some embodiments of the present disclosure, if the duration exceeds the third preset duration, the period set to avoid frequent switching has passed, and at this time, the first transmission link (the primary transmission link used preferentially) may be switched back. Specifically, the provided terminal data transmission method, after monitoring the duration from the moment when the terminal starts transmitting data through the second transmission link to the current moment, further includes:

[0076] When the duration exceeds a third preset duration, the terminal is controlled to transmit data through the first transmission link, and the accumulated link switching times of the terminal are cleared.

[0077] It should be noted that at this time, the cumulative number of link switching times of the terminal is reset to zero, and the round ends at the same time. A new round needs to be started to re-monitor the quality indicator information of the terminal transmitting data through the first transmission link within the first preset time period to switch the transmission link.

[0078] In some embodiments of the present disclosure, when the control terminal transmits data through the second transmission link, the transmission quality of the second transmission link is always good, that is, the quality index information of the terminal transmitting data through the second transmission link has not met the preset index threshold condition within the second preset time period. In order to ensure the priority of the main transmission link (the first transmission link), after transmitting data through the second transmission link for a period of time, it is still necessary to switch back to the first transmission link. Figure 5 The terminal data transmission method shown in the figure further includes the following steps after monitoring the quality indicator information of the data transmitted by the terminal through the second transmission link within the second preset time period:

[0079] S502, when the quality indicator information of the data transmitted by the terminal through the second transmission link within the second preset time period does not meet the preset indicator threshold condition, monitor the duration from the moment when the terminal starts to transmit data through the second transmission link to the current moment;

[0080] S504: When the duration exceeds a fifth preset duration, control the terminal to transmit data through the first transmission link, and clear the accumulated link switching times of the terminal.

[0081] It should be noted that the fifth preset duration is greater than the third preset duration. The duration monitored from the moment the terminal starts transmitting data through the second transmission link to the current moment is consistent with the duration monitored by S304. When the duration exceeds the fifth preset duration, the terminal is controlled to transmit data through the first transmission link, and the cumulative number of link switching times of the terminal is cleared. At this time, the current round ends, and a new round begins. The quality indicator information of the terminal transmitting data through the first transmission link in the first preset time period is re-monitored, and subsequent steps are performed. And when the duration does not exceed the fifth preset duration, the quality indicator information of the terminal transmitting data through the second transmission link in the second preset time period is re-monitored, and then it is determined whether the quality indicator information of the terminal transmitting data through the second transmission link in the second preset time period meets the preset indicator threshold condition, and subsequent operations are performed until the end of this round.

[0082] In order to better illustrate the terminal data transmission method provided by the embodiment of the present disclosure, a specific example is now given for further explanation. Figure 6 The figure shows the execution process of the master-slave data diversion strategy of the terminal data transmission method provided in the embodiment of the present disclosure.

[0083] exist Figure 6 In the process shown, the meanings of the defined parameters are:

[0084] T1: The time window for the terminal to detect packet loss and retransmission on the primary transmission link.

[0085] T2: The time window for the terminal to detect packet loss and retransmission on the backup transmission link.

[0086] T3: The timing of the priority timer. When the terminal transmits data on the backup transmission link for more than the time set by T3, the terminal should switch back to the main transmission link and re-check whether the channel quality meets the data transmission requirements because the definition of the terminal's primary and backup priority is that the primary transmission link takes priority.

[0087] T4: A time window defined to avoid frequent ping-pong switching. When the T4 timer has not timed out and the number of switching times W exceeds the maximum number of switching times W1, the terminal will stop the transmission link switching and reset the number of switching times W. The value of T3 must be greater than T4.

[0088] T5: Ping-pong protection time window. This timer is enabled after deciding to stop link switching. Transmission is always maintained on the original link within T5. The link status is monitored again after T5 times out.

[0089] L1: The preset threshold of the average packet loss rate corresponding to the primary transmission link.

[0090] S1: The preset threshold of the number of retransmissions corresponding to the primary transmission link.

[0091] L2: preset threshold of the average packet loss rate corresponding to the backup transmission link.

[0092] S2: a preset threshold of the number of retransmissions corresponding to the backup transmission link.

[0093] The values ​​of L1 and L2 may be the same or different, and the values ​​of S1 and S2 may be the same or different.

[0094] The specific implementation process includes:

[0095] After the terminal is turned on, it connects to Wi-Fi and cellular networks at the same time and starts data transmission. The data diversion technology is adopted as the primary-backup mode, that is, the link with a higher set priority is selected as the main transmission link. When the main transmission link is available, data is transmitted on the main transmission link. When the main transmission link is unavailable, data transmission is switched to the backup transmission link.

[0096] When the terminal starts to transmit data on the primary transmission link, the T1 timer is started to continuously monitor the packet loss rate and the number of retransmissions at the MAC sublayer of the primary transmission link.

[0097] If within the T1 time window, the average packet loss rate of the terminal is greater than L1 and the number of retransmissions is greater than S1, it is determined that the primary transmission link has serious packet loss, the channel state is poor, the transmission efficiency is low, and it is necessary to switch to the backup transmission link.

[0098] The terminal directs the data traffic to the backup transmission link, activates the T3 priority timer and the T4 protection timer, and the number of switching times W=W+1, and at the same time informs the data receiver through signaling that the transmission link has changed. Specifically, if the offloading technology uses the MPTCP (Mutipath TCP) offloading technology, the permanent switching path priority uses the MP_PRIO signaling, that is, whether the current transmission link is used as a backup transmission link can be indicated by whether the identifier "B" is carried in the MP_PRIO signaling. "B" means backup. When the transmission link changes, the terminal can send MP_PRIO signaling to inform the other party that the data link has changed. For example, when the terminal directs the data traffic to the original backup transmission link, "B" can be removed in the transmitted MP_PRIO signaling to inform the data receiver that this data link is no longer a backup transmission link, but a transmission link currently in use.

[0099] When the terminal transmits data on the backup transmission link, if within T2, the average packet loss rate of the terminal is greater than L2 and the number of retransmissions is greater than S2, then if the T4 protection timer has not timed out and the number of switching times W is not greater than the maximum number of switching times W1, the terminal will redirect the data traffic to the main transmission link again, and continue to monitor the average packet loss rate and retransmission times on the main transmission link within T1, and increase the number of switching times W=W+1. If it is detected that the channel state of the main transmission link meets the requirements, the main transmission link is kept unchanged and the monitoring continues; if it is detected that the channel state of the main transmission link is poor, the data traffic is directed to the backup transmission link again, and the average packet loss rate and retransmission times on the backup transmission link within T2 are monitored. If the monitoring result shows that the channel state of the backup transmission link meets the requirements, the backup transmission link is kept and the monitoring continues; if it is detected that the channel state of the backup transmission link is poor, the data traffic is directed to the main transmission link, and so on. Each switching will increase W by one until the T4 protection timer times out or W is greater than W1.

[0100] If the T4 protection timer has not timed out and the number of switching times W is greater than the maximum number of switching times W1, the terminal will enable the T5 timer. Before the T5 timer times out, it will continue to transmit on the existing transmission link and will not switch the transmission link to prevent the ping-pong effect caused by frequent switching. If the T5 timer times out, W will be set to 0, and the T4 protection timer will be re-determined to see if it has timed out, and the subsequent steps will be continued.

[0101] If the T4 protection timer has timed out, the switching times W are reset to 0, and the data is switched back to the main transmission link, returning to the beginning of a new round.

[0102] When the terminal transmits data on the backup transmission link, if within T2, the average packet loss rate of the terminal is not detected to be greater than L2 and the number of retransmissions is not greater than S2, before the T3 priority timer expires, the average packet loss rate and the number of retransmissions within T2 are re-monitored and a new judgment is made. After the T3 priority timer expires, the switching times W are reset to 0, and the data is switched back to the main transmission link, returning to the beginning of a new round.

[0103] From the above process, it can be seen that this specific example can more flexibly adjust the transmission of data between the main transmission link and the backup transmission link, solving the problem of low transmission efficiency due to a large number of packet loss and retransmission when the signal of the main transmission link is very weak but still connectable. At the same time, multiple timers and jump logics are designed to ensure that after the quality of the main transmission link channel is restored, the data can be switched back to the main transmission link for transmission first, while also avoiding the ping-pong effect caused by frequent switching of transmission links in a short period of time.

[0104] It should be noted that the acquisition, storage, use, and processing of data in the technical solution disclosed in this disclosure are in compliance with the relevant provisions of national laws and regulations.

[0105] Based on the same inventive concept, the present disclosure also provides a terminal data transmission device, as described in the following embodiments.
