detailed description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

It should be noted that "and/or" in the embodiment of the present application is only an association relationship describing the associated objects, which means that there may be three kinds of relationships. For example, A and/or B means: A alone exists, A and B exist at the same time, and B exists alone.

In the description and claims of the embodiments of the present application, "first" and "second" etc. are used to distinguish different objects, but are not used to describe the specific order of the objects, nor are they used to limit the specific quantity. For example, the first target object and the second target object are used to distinguish different target objects, not to describe a specific order of the target objects, nor to limit the specific number of the target objects.

In the embodiments of the present application, "exemplary" or "for example" and the like are used as examples, illustrations or descriptions. Any embodiment or design described in the embodiments of the present application as "exemplary" or "such as" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present the related concepts in a specific manner.

In the description of the embodiments of the present application, unless otherwise specified, the meaning of "plurality" refers to two or more.

Generally speaking, any kind of network has dead space in coverage, such as Wi-Fi network and cellular network. When the mobile device is located in the dead zone area, the mobile device only uses one kind of network, and the transmission rate of this kind of network will be low, which will affect the user's use. Or, the network performance in the area where the mobile device is located is good, but there are many mobile devices, which will also reduce the transmission rate and affect the use of the user. Take a Wi-Fi network as an example. For example, when a user is dining in a restaurant, if the Wi-Fi network performance of the user in the restaurant is poor, such as insufficient bandwidth, when the user watches high-throughput services such as online video through a mobile device, the video will often freeze, affecting the user. experience. If the performance of the Wi-Fi network at the user in the restaurant is good, for example, the bandwidth is good, but the number of mobile devices connected to the Wi-Fi network is large, which increases the interference between mobile devices and reduces the transmission rate. When viewing high-throughput services such as online video on mobile devices, the video often freezes, affecting user experience.

In order to solve the problem that the transmission rate may be low under a single network and affect the use of users, multiple network transmission methods have been introduced. For example, the two-way transmission method of Wi-Fi network and cellular network. The two-way transmission method of Wi-Fi network and cellular network can quickly supplement the signal of one network when the signal of the other network is weak, and stabilize the transmission rate, which is widely used. This method can realize dual uplink aggregation of the cellular network and the Wi-Fi network, that is, a dual transmission channel of the cellular network and the Wi-Fi network can be established simultaneously between the mobile device and any application server. The application server is a server corresponding to the application accessed by the mobile device after opening an application in order to obtain the data of the application and/or realize the function of the application. For example, if instant messaging application A is installed on a mobile device, after the user clicks the icon of instant messaging application A on the mobile device, the application server corresponding to instant messaging application A receives a request from the user to start the application, and the application server Return the corresponding data to the mobile device.

The following takes the architecture shown in FIG. 1 as an example to further illustrate by way of example. As shown in FIG. 1 , the system of the dual transmission mode of the Wi-Fi network and the cellular network includes a mobile device 101 , a first application server 102 and a second application server 103 . The mobile device 101 is installed with a client software development kit (client_Software Development Kit, C_SDK), and both the first application server 102 and the second application server 103 are installed with a server software development kit (server_Software Development Kit, S_SDK). Among them, C_SDK is a client software development kit that transmits data to and from S_SDK through two-way transmission; C_SDK is responsible for the establishment of the transmission channel of the mobile device 101, the measurement of the transmission channel, the unpacking and sending of data packets, the combination of data packet reception and the service whitelist. Wait. S_SDK is a server-side software development kit that transmits data to and from C_SDK through two-way transmission; S_SDK is responsible for data packet reception and aggregation in application servers (102 and 103), and data packet splitting and sending. The mobile device 101 connects to the first application server 102 through the cellular network 104 and the Wi-Fi network 105 to realize dual transmission; similarly, the mobile device 101 connects to the second application server 103 through the cellular network 104 and the Wi-Fi network 105 to realize dual transmission. road transmission. Taking the communication between the mobile device 101 and the first application server 102 as an example, when the performance of the Wi-Fi network 105 is good, the mobile device 101 transmits data to the first application server 102 through the Wi-Fi network 105, and the first application Server 102 transmits data to mobile device 101 via Wi-Fi network 105; cellular network 104 may not be used at this time, or cellular network 104 may be used with less bandwidth of cellular network 104. When the performance of the Wi-Fi network 105 is poor, the mobile device 101 transmits data to the first application server 102 through the cellular network 104, and the first application server 102 transmits data to the mobile device 101 through the cellular network 104; at this time, the Wi-Fi network 105 may not be used, or the Wi-Fi network 105 may be used with less bandwidth. In this way, the overall transmission bandwidth of the two networks remains the same, or the change is small. Even when the user is watching high-throughput services such as online video, the video will maintain the same smoothness, and the user experience will be better.

It should be noted that the system of the dual transmission mode of the Wi-Fi network and the cellular network shown in FIG. 1 further includes: a routing device 106 . The mobile device 101 transmits data to the routing device 106 through the Wi-Fi network 105, and the routing device 106 transmits the data to the first application server 102 and the second application server 103 respectively, and the first application server 102 and the second application server 103 through the Wi-Fi The Fi network 105 respectively transmits the data to the routing device 106 , which in turn transmits the data to the mobile device 101 .

The first application server 102 is taken as an example for description. Specifically, when the mobile device 101 has a service data request, the C_SDK in the mobile device 101 determines whether the corresponding service is in the service whitelist. If so, the C_SDK can distribute different data packets to the two transmission channels simultaneously to the first application according to the respective capabilities (such as bandwidth and/or delay) of the transmission channels of the cellular network 104 and the Wi-Fi network 105 S_SDK in server 102. At the same time, the S_SDK detects and receives the data packets on the two transmission channels, and aggregates the data packets received from the two transmission channels based on the combination sequence of the originating end to obtain the data request of the mobile device 101 . The S_SDK obtains a data response based on the data request of the mobile device 101 . The S_SDK splits the data response into different data packets, and distributes the different data packets to the two transmission channels and sends them to the C_SDK in the mobile device 101 at the same time. At the same time, the C_SDK detects and receives the data packets on the two transmission channels, and aggregates the data packets received from the two transmission channels based on the combination sequence of the originator to obtain a data response. The C_SDK then transfers the data response to the application corresponding to the mobile device 101, so that the application implements the corresponding service. Therefore, the two-way transmission between the mobile device 101 and the application server 102 increases the bandwidth and reduces the delay.

It should be noted that the first application server 102 and the second application server 103 in FIG. 1 are only illustrative examples of application servers, and are not used to limit the number of application servers. In fact, the application servers correspond to the applications installed on the mobile device 101, and the number of application servers may reach thousands or even more.

However, the above-mentioned multiplex transmission modes of various networks require that the mobile device and all the application servers that the mobile device may be connected to be pre-adapted, resulting in high cost and unfavorable promotion. Still take the system architecture of the dual transmission mode of the Wi-Fi network 105 and the cellular network 104 in FIG. 1 as an example. In FIG. 1 , the mobile device 101 needs to be pre-installed with C_SDK, and both the first application server 102 and the second application server 103 need to be pre-installed with S_SDK. That is to say, the application server corresponding to the application installed on the mobile device 101 needs to be pre-installed with S_SDK. For example, the mobile device 101 is installed with 100 different applications, and the application servers corresponding to the 100 applications need to follow the S_SDK in advance. This makes the promotion of the above methods subject to certain restrictions, and the promotion cost is relatively high. How to provide a two-way transmission method of Wi-Fi network and cellular network that is conducive to promotion has become our demand.

If the mobile device 100 accesses the Wi-Fi network 400 of the routing device 200, the routing device 200 can assign an IP address to the WAN interface 1 of the mobile device 100 corresponding to the Wi-Fi network 400, such as 192.168.1.1, or 192.168. 1.10, so that the mobile device 100 and the routing device 200 can mutually transmit data via the first transmission channel.

The second transmission channel refers to the transmission channel established through the cellular network 500 , that is, the transmission channel between the mobile device 100 and the routing device 200 through the cellular network 500 . Among them, the common types of cellular network 500 are: global system for mobile communications (GSM) network, enhanced data rate for GSM evolution (EDGE) network, wideband code division multiple access System (wideband code division multiple access, WCDMA) network, code division multiple access 2000 system (code division multiple access, CDMA2000) network, time division synchronous code division multiple access system (time division-synchronization code division multiple access, TD-SCDMA) network , Long Term Evolution (LTE) network, 5G New Radio (NR) network and next-generation mobile network, etc.

In this application, the first SDK is deployed in the mobile device 100 . The first SDK is used to support the mobile device 100 and the routing device 200 to establish the first transmission channel and the second transmission channel at the same time. The first SDK is responsible for the establishment of the second transmission channel, actively negotiates with the routing device 200 to determine whether the service requirements are met, detects and evaluates the connection status and channel quality of the first transmission channel and the second transmission channel in real time, and can complete the communication with the cloud.

It should be noted that the differences between the first SDK and C_SDK are: 1. The destination IPs of the two are different. The destination IP of the first SDK is the routing device 200, and the destination IP of the C_SDK is the corresponding application server. 2. The headers of the data packets are processed differently. The packet header processing method of the first first SDK: the packet header of the data packet on the first transmission channel does not do any processing, and the packet header of the data packet on the second transmission channel needs to add IP. The header processing method of the data packet of C_SDK: All data packets must rebuild the header of adding IP. Therefore, the packet header processing operation of the data packet of the present application is reduced, and the processing efficiency is improved. 3. The second transmission channel established by the first SDK may include: the transmission channel between the WAN interface 2 of the mobile device 100 corresponding to the cellular network 500 and the WAN interface 4 of the routing device 200, or the mobile device 100 and the cellular network.

It should be noted that the difference between the second SDK and the S_SDK is that the packet receiving mechanism is different. The second SDK receives data packets from the LAN interface 3 of the routing device 200 via the first transmission channel, and receives data packets from the WAN interface 4 of the routing device 200 via the second transmission channel, and then aggregates the data packets. The S-SDK obtains data packets on each path from the service access port of the application server.

Wherein, this application does not limit the specific representation of the service type. For example, a whitelist is stored in the SA module, and various service types are stored in the whitelist, which is used to indicate that the service corresponding to the service type can be implemented through the MP. Thus, the SA module can identify whether the service type of the service application is in the whitelist. If it exists, the SA module can determine that the service application can implement the service of the service application through the MP, and can trigger the first MP policy module to start the MP.

Table 3 Network parameters of services

The protocol of the MP is a protocol supported by the MP, including protocol types such as MPTCP or MPUDP. In general, the protocol adopted by each transmission channel in the MP is the same.

In this application, MPTCP defines the MP protocol extension based on the request for Comments (RFC) standard to support the following three MP mode types.

Mode 1: Aggregation Mode

When initiating MPTCP, the mobile device 100 will establish a link that aggregates MPTCP, including two subflows, namely the Wi-Fi network subflow (ie the first transmission channel) and the LTE network subflow (ie the second transmission channel). In the case that both the Wi-Fi network and the LTE network are normal, the mobile device 100 splits the upload data according to the MP policy and the transmission capabilities of the Wi-Fi network and the LTE network and allocates them to the first transmission channel and the second transmission respectively. Data packets are transmitted over the channel for double the bandwidth of Wi-Fi and LTE networks.

Mode 2: Redundant Mode

When initiating MPTCP, the mobile device 100 will establish a redundant MPTCP link, including two sub-streams, namely the Wi-Fi network sub-flow (ie the first transmission channel) and the LTE network sub-flow (ie the second transmission channel). When both the Wi-Fi network and the LTE network are normal, the mobile device 100 copies the uploaded data in two copies, and transmits them simultaneously on the first transmission channel and the second transmission channel respectively, so that the uploaded data reaches the route via any transmission channel. The device 200, the routing device 200 receives the upload data on the first transmission channel and the second transmission channel at the same time, and adopts the principle of first-come-first-use, last-to-discard to obtain lower latency and end-to-end "zero" packet loss. experience.

Mode 3: Active-standby mode

When initiating MPTCP, the mobile device 100 will establish an active and standby MPTCP link, including a total of two links of the active Wi-Fi network sub-flow and the standby LTE network sub-flow. When both the Wi-Fi network and the LTE network are normal, the mobile device 100 will use the primary Wi-Fi network substream to transmit data. In the event of a Wi-Fi network failure, the mobile device 100 will automatically switch to the LTE network sub-stream to transmit data to ensure network availability.

It should be noted that the active-standby mode can be applied to the scenario where the communication between the mobile device 100 and the routing device 200 through MP (referred to as MP communication) occurs abnormally, and the mobile device 100 can automatically switch to the transmission channel that can transmit data normally to ensure that data Transmission stability.

In this application, MPUDP is a protocol tunnel carried over UDP. Currently, an active-standby mode and a redundant mode are provided to obtain a low-latency and highly reliable network experience.

For the specific implementation process of the active-standby mode and the redundant mode of MPUDP, please refer to the specific contents of the active-standby mode and the redundant mode of MPTCP, which will not be repeated here. In addition, the difference between MPUDP and MPTCP is: under MPUDP, after the mobile device 100 sends a data packet to the routing device 200, the mobile device 100 needs to receive the response sent by the routing device 200 before sending the next packet to the routing device 200. a packet.

In addition, in this application, the routing device 200 may also stop communicating with the mobile device 100 through the MP.

In the following, various feasible implementation manners for the routing device 200 to stop the MP communication are given as examples.

In a feasible implementation manner, if the second NAT module of the routing device 200 detects that the IP address and port information of the gateway 700 of the routing device 200 are incorrect, the second NAT module of the routing device 200 can report to the second NAT module of the routing device 200 The second MP policy module module sends a corresponding instruction, so that the second MP policy module module of the routing device 200 releases the MP resources related to the applied service, such as the IP quintuple of the applied service, so that the routing device 200 can stop passing through the MP The first transmission channel and the second transmission channel communicate with the mobile device 100.

The IP quintuple is IP triplet+source IP (that is, the IP address of the mobile device 100)+source port (that is, the port information of the mobile device 100). The IP triplet may include: the service type of the application, the destination IP (that is, the IP address of the application server 300 ), and the destination port (that is, the port information of the application server 300 ).

In another feasible implementation manner, if the MP protocol server module of the routing device 200 detects that any transmission channel in the MP is abnormal or interrupted, the MP protocol server module of the routing device 200 can send a message to the second MP of the routing device 200 The policy module module sends an instruction instruction, so that the second MP policy module module of the routing device 200 releases the MP resources related to the applied service, so that the routing device 200 can stop communicating with the mobile device 100 through the first transmission channel and the second transmission channel in the MP. to communicate.

In another feasible implementation manner, if the second data proxy module of the routing device 200 detects a data packet corresponding to a service that is not applied on each transmission channel in the MP after a preset time period, the second data proxy module of the routing device 200 The data proxy module can send an instruction instruction to the second MP policy module module of the routing device 200, so that the second MP policy module module of the routing device 200 releases the MP resources related to the applied service, so that the routing device 200 can stop passing the first MP resource in the MP. A transmission channel and a second transmission channel communicate with the mobile device 100 . The specific value of the preset duration is not limited in this application, and can be set according to the actual situation.

In another feasible implementation manner, if the MP protocol server module of the routing device 200 receives a message sent by the MP protocol client module of the mobile device 100 to indicate that communication through MP is stopped, the MP protocol server module of the routing device 200 The module can send an instruction instruction to the second MP policy module module of the routing device 200, so that the second MP policy module module of the routing device 200 releases the MP resources related to the applied service, so that the routing device 200 can stop passing the first transmission in the MP. The channel and the second transmission channel communicate with the mobile device 100 .

To sum up, the present application is not limited to the above several possible implementation manners to realize that the routing device 200 and the mobile device 100 stop communicating through the MP. In addition, the mobile device 100 may also stop communicating with the routing device 200 through the MP through the above possible implementation manners.

Based on the foregoing description and with reference to FIG. 6 , the specific implementation process of the communication method of the present application is described in detail by taking the mobile device 100 , the routing device 200 and the M application servers 300 in the communication system of the embodiment shown in FIG. 2 as execution subjects. In FIG. 6 , the mobile device 100 and the routing device 200 establish a first transmission channel through the Wi-Fi network 400 .

FIG. 6 is a signaling flowchart of a communication method provided by an embodiment of the present application. As shown in Figure 6, the communication method of the present application may include:

S101. After the mobile device detects that the bandwidth occupied by the mobile device on the Wi-Fi network is less than a preset first threshold, and/or after the mobile device detects that the transmission delay of the mobile device through the Wi-Fi network is greater than a preset first threshold After two thresholds, the mobile device and the routing device establish a second transmission channel through the cellular network.

In this application, the mobile device 100 may preset network parameters of various types of services, as shown in Table 3. For any one of the N applications, after the mobile device 100 detects that the bandwidth occupied by the mobile device 100 of the Wi-Fi network 400 is less than the preset first threshold, and/or, after the mobile device 100 detects that the mobile device 100 has passed the After the transmission delay of the Wi-Fi network 400 is greater than the preset second threshold, the mobile device 100 may determine that the current Wi-Fi network 400 cannot meet the service requirements of the application. Therefore, the mobile device 100 and the routing device 200 can establish a second transmission channel through the cellular network 500, thereby providing a more efficient two-way transmission method for the application to realize the corresponding service in time through the first transmission channel and the second transmission channel .

The specific implementation process of establishing the second transmission channel between the mobile device 100 and the routing device 200 may include the following steps:

Step 1: During the running process of the application, the mobile device 100 can determine whether the service of the application can be communicated through the MP.

In some embodiments, the mobile device 100 connects to the routing device 200 via the Wi-Fi network 400 to access the Internet. During the running process of the application, the SA module of the mobile device 100 can identify the service type of the application, and when determining the service type of the application included in the whitelist, the SA module of the mobile device 100 can determine that the service of the application can communicate through the MP. Conversely, the SA module of the mobile device 100 may determine that the application's service cannot be communicated through the MP.

Step 2: The mobile device 100 determines whether the MP has been activated when it is determined that the service of the application can be communicated through the MP.

In some embodiments, the SA module of the mobile device 100 may notify the first MP policy module of the mobile device 100 when determining that the service of the application can communicate through the MP. The first MP policy module of the mobile device 100 may call the first channel management module of the mobile device 100 to check the network capability of each transmission channel in the MP. The first MP policy module of the mobile device 100 determines whether the MP has been activated based on the network capability of the transmission channel serving the service of the application.

If the MP is activated, the mobile device 100 and the routing device 200 do not need to establish a second transmission channel, and the mobile device 100 may execute S102.

If the MP is not activated, for any one of the N applications, after the mobile device 100 determines whether the bandwidth occupied by the mobile device 100 of the Wi-Fi network 400 is less than the preset first threshold, or the mobile device 100 passes the Wi-Fi Whether the transmission delay of the network 400 is greater than the preset second threshold. Therefore, after the mobile device 100 detects that the bandwidth occupied by the mobile device 100 of the Wi-Fi network 400 is less than the preset first threshold, and/or when the mobile device 100 detects that the mobile device 100 transmits through the Wi-Fi network 400 After the delay is greater than the preset second threshold, the mobile device 100 and the routing device 200 establish a second transmission channel. In addition, the mobile device 100 can also determine conditions such as whether the mobile device 100 is in an activated state, and whether the service protocol type supported by the mobile device 100 includes the preset protocol type of the MP.

In other embodiments, the first MP policy module of the mobile device 100 obtains the IP quintuple and preset network parameters (such as bandwidth, delay, number of links, etc.) of the application service from the SA module based on the application service. requirements), the MP capability information of the mobile device 100 and other parameters, and notify the first data proxy module of the mobile device 100 to reroute the data packets of the IP quintuple of the application-based service, that is, to transmit through the MP, so that the mobile device 100 The first data proxy module diverts the corresponding data packets to the MP protocol client module of the mobile device 100 based on the IP quintuple of the service of the application.

The preset network parameters of the applied service are used to represent the network QoS requirements preconfigured by the mobile device 100 for different services, such as requirements such as bandwidth, delay, number of links, etc. Please refer to the network parameters in Table 2. For example, the preset bandwidth threshold of the service is used to indicate the corresponding bandwidth range of each service when the mobile device 100 communicates with the routing device 200 through the MP, such as a maximum bandwidth value or a minimum bandwidth value. The preset delay threshold of the service is used to indicate the delay range of each service when the mobile device 100 communicates with the routing device 200 through the MP, such as the maximum delay value or the minimum delay value.

The MP capability information of the mobile device 100 may include, but is not limited to, parameters such as MP support state, MP capability set, and working state of the mobile device 100 . The MP support status of the mobile device 100 is used to indicate whether the mobile device 100 supports MP. The MP capability set of the mobile device 100 is used to indicate the MP capability possessed by the mobile device 100 . The MP capability set of the mobile device 100 may include, but is not limited to, the protocol type of the MP, the mode type of the MP, the network type of each transport channel in the MP, and the number of transport channels (such as the network type of each transport channel and the network type of each transport channel). type of transmission channels). The working state of the mobile device 100 is used to indicate whether the mobile device 100 starts the MP or stops the MP.

It should be noted that, after the mobile device 100 detects that the bandwidth of the Wi-Fi network 400 occupied by the mobile device 100 is greater than or equal to the preset first threshold, and/or, after the mobile device 100 detects that the mobile device 100 uses the Wi-Fi network After the transmission delay of the network 400 is less than or equal to the preset second threshold, the mobile device 100 may determine that the current Wi-Fi network 400 can meet the service requirements of the application. Therefore, the mobile device 100 transmits the upload data to the routing device 200 via the first transmission channel, and the routing device 200 transmits the request response to the mobile device 100 via the first transmission channel.

S102. The mobile device splits the uploaded data into first data and second data, transmits the first data to the routing device via the first transmission channel, and transmits the second data to the routing device via the second transmission channel. The uploaded data is data to be transmitted to the Pth application server among the M application servers, and P is a positive integer greater than or equal to 1 and less than or equal to M.

In this application, the mobile device 100 can split the uploaded data into first data and second data based on the MP policy of the applied service, and transmit the first data to the routing device 200 via the first transmission channel, and the second data It is transmitted to the routing device 200 via the second transmission channel.

Wherein, the present application does not limit the specific implementation manners of the uploaded data, the first data and the second data. For example, each data packet in the uploaded data may be in the format of packet header + packet body, or may be in the format of packet header + packet body + packet tail.

In some embodiments, the first data proxy module of the mobile device 100 initiates the transmission of the IP quintuple data packets of the application-based service through the MP, so that the first data proxy module of the mobile device 100 according to the mode type of the MP and the MP of the protocol type, the upload data is split into first data and second data, and the first data and second data are transmitted to the MP protocol client module of the mobile device 100. The MP protocol client module of the mobile device 100 reroutes the first data to the Wi-Fi AP of the routing device 200 via the first transmission channel, and reroutes the second data to the WAN interface 4 of the routing device 200 via the second transmission channel, The MP protocol server module of the routing device 200 receives the first data and the second data. The MP protocol server module of the routing device 200 then sends the first data and the second data to the second data proxy module of the routing device 200 .

In addition, the split mode of the uploaded data can also be configured adaptively based on the protocol type of the MP.

In the following, taking the MP including the first transmission channel established through the Wi-Fi network 400 and the second transmission channel established through the LTE network, and the protocol type of the MP being MPTCP as an example, the mobile device 100 sends the first transmission channel to the routing device 200 through the MP. The specific implementation process of the data and the second data is given as an example.

When the mode type of the MP is the aggregation mode, the mobile device 100 may divide the uploaded data into the first data and the second data.

For the first data on the first transmission channel, the mobile device 100 may add a number corresponding to each data packet in the packet header of each data packet in the first data. The number is used for the mobile device 100 or the routing device 200 to sort the data packets on the MP to obtain complete data. The number may occupy one or more bits, which is not limited in this application.

For the second data on the second transmission channel, the mobile device 100 may add the IP address and port information of the WAN interface 4 of the routing device 200 and the number corresponding to each data packet in the header of each data packet in the second data Or, the mobile device 100 may add the IP address and port information of the gateway 700 of the routing device 200 and the number corresponding to each data packet in the header of each data packet in the second data.

It should be noted that when the mode type of the MP is the redundant mode, the mobile device 100 does not need to split the upload data, and can transmit the upload data on both the first transmission channel and the second transmission channel. For the formats of the data packets on the first transmission channel and the second transmission channel, please refer to the foregoing description of the format of the data packets on the first transmission channel and the second transmission channel when the mode type of the MP is the aggregation mode. Do repeat.

In some embodiments, the first data agent module of the mobile device 100 implements the service of the application based on the downloaded data. For example, a video application on a mobile phone implements video playback.

In the communication method provided by the present application, a first transmission channel is established by a mobile device and a routing device through a Wi-Fi network, and a second transmission channel is established by the mobile device and the routing device through a cellular network.

Based on the foregoing description and in conjunction with FIG. 7 , taking the mobile device 100 and the routing device 200 in the communication system of the embodiment shown in FIG. 2 as the execution subjects, in S101 of the present application, when the mobile device detects that the mobile device occupies the bandwidth of the Wi-Fi network After being less than the preset first threshold, and/or after the mobile device detects that the delay of the mobile device transmission through the Wi-Fi network is greater than the preset second threshold, the mobile device and the routing device establish a second transmission through the cellular network. The specific implementation process of the channel is described in detail.

FIG. 7 is a signaling flowchart of a communication method provided by an embodiment of the present application. As shown in Figure 7, the communication method of the present application may include:

S201. After the mobile device detects that the bandwidth occupied by the mobile device on the Wi-Fi network is less than a preset first threshold, and/or when the mobile device detects that the transmission delay of the mobile device through the Wi-Fi network is greater than a preset first threshold After two thresholds, the mobile device sends the first request to the routing device via the first transmission channel. The first request is a request for inquiring whether the routing device has the capability of multiplexing data. The first request carries preset network parameters of the service of the application and MP capability information of the mobile device.

S202. After the routing device receives the first request of the mobile device via the first transmission channel and determines that the routing device has the capability of multiplexing data, the routing device sends a first response to the mobile device via the first transmission channel. The first response is a response to the first request, and is used to indicate that the routing device has the capability of multiplexing data.

In this application, after the mobile device 100 detects that the bandwidth occupied by the mobile device 100 of the Wi-Fi network 400 is less than the preset first threshold, and/or, after the mobile device 100 detects that the mobile device 100 transmits data through the Wi-Fi network 400 After the delay is greater than the preset second threshold, the mobile device 100 may determine that the MP needs to be activated.

After the mobile device 100 starts MP, the mobile device 100 may send a first request to the routing device 200, so that the routing device 200 obtains preset network parameters of the application service and MP capability information of the mobile device 100 from the first request. Therefore, the routing device 200 can determine whether the actual network conditions of the routing device 200 (such as the network QoS of parameters such as bandwidth and delay of the WAN interface 4 of the routing device 200) can satisfy the preset network parameters of the application service, and the routing The device 200 can also determine whether the MP capability information of the routing device 200 matches the MP capability information of the mobile device 100, that is, whether the protocol type of the MP is satisfied, whether the mode type of the MP is satisfied, and whether the number of transmission channels of the MP is satisfied, etc.

Wherein, the MP capability information of the routing device 200 may include, but is not limited to: MP support status, MP capability set, working status, and the like of the routing device 200 . The MP support status of the routing device 200 is used to indicate whether the routing device 200 supports MP. The MP capability set of the routing device 200 is used to indicate the MP capabilities possessed by the routing device 200 . The MP capability set of the routing device 200 may include, but is not limited to, the protocol type of the MP, the mode type of the MP, the network type of each transmission channel in the MP, and the number of transmission channels. The working status of the routing device 200 is used to indicate whether the routing device 200 starts the MP or stops starting the MP.

Therefore, the routing device 200 can determine whether the routing device 200 has the capability of multiplexing data, which facilitates the mobile device 100 to determine whether the routing device 200 supports MP. When routing device 200 has the capability to multiplex data, routing device 200 sends a first response to mobile device 100 .

In some embodiments, after starting the MP, the first MP policy center module of the mobile device 100 may call the MP protocol client module of the mobile device 100 to send the first request to the MP protocol server module of the routing device 200 . Thus, the mobile device 100 may inquire the routing device 200 whether the routing device 200 supports MP through the first request.

The MP protocol server module of the routing device 200 forwards the first request to the second MP policy center module of the routing device 200 . The second MP policy center module of the routing device 200 obtains the MP capability information of the routing device 200 from the proxy information module of the routing device 200, and obtains the routing device 200 from the WAN interface 4 of the routing device 200 from the second connection management module of the routing device 200 The actual network QoS of the first transmission channel. Therefore, the second MP policy center module of the routing device 200 can determine whether the protocol type of the MP of the routing device 200 is satisfied, whether the mode type of the MP is satisfied, and the actual network QoS of the first transmission channel of the routing device 200 (such as delay, parameters such as bandwidth) are satisfied, etc., to determine whether the routing device 200 supports MP.

Therefore, when the routing device 200 determines that the routing device 200 has the capability of multiplexing data, the second MP policy module of the routing device 200 drives the MP protocol server module of the routing device 200 to send the first response to the MP protocol client module of the mobile device 100 , the MP protocol client module of the mobile device 100 forwards the first response to the first MP policy module.

It should be noted that the first response may not carry the IP address and port information of the WAN interface 4 of the routing device 200 of the routing device 200, and the routing device 200 may transmit the IP address and port information of the WAN interface 4 of the routing device 200 to The cloud server 800 enables the mobile device 100 to obtain the IP address and port information of the WAN interface 4 of the routing device 200 from the cloud server 800 by means of account binding or the like.

S203. After the mobile device determines that the routing device has the capability of multiplexing data, the mobile device sends a second request to the routing device through the cellular network. Wherein, the second request is a request for performing Internet packet explorer (packet internet groper, PING) detection on the transmission channel between the WAN interface corresponding to the cellular network and the WAN interface of the routing device.

Because the network capability of each transmission channel in the MP will be affected by various factors such as the operator's Internet, the mobile device 100, the routing device 200, and the external environment. Therefore, the mobile device 100 can perform PING detection on the IP address and port information of the WAN interface 4 of the routing device 200 to determine whether the mobile device 100 can communicate with the routing device 200 via the WAN interface 4 of the routing device 200 through the cellular network 500, Therefore, it is determined that the second transmission channel can transmit data to each other, which ensures the effective transmission of data packets, so that the mobile device 100 can smoothly communicate with the routing device 200 through the MP.

In some embodiments, the first MP policy module of the mobile device 100 invokes the first channel management module of the mobile device 100 to initiate a PING probe for the IP address and port information of the WAN interface 4 of the routing device 200 .

S204. The mobile device determines whether a second response from the routing device is received through the cellular network within a preset time period, where the second response is a response to the second request.

If the mobile device 100 does not receive the second response from the routing device 200 through the cellular network 500 within a preset period of time, the mobile device 100 determines to perform PING detection on the IP address and port information of the WAN interface 4 of the routing device 200 through the cellular network 500 If it fails, the mobile device 100 can execute steps S2051-S2052.

If the mobile device 100 receives the second response from the routing device 200 through the cellular network 500 within the preset time period, the mobile device 100 determines that the PING detection of the IP address and port information of the WAN interface 4 of the routing device 200 through the cellular network 500 is successful. , so that the mobile device 100 can execute step S206.

It should be noted that S203 is an optional step, that is, in general, the cellular network 500 of the mobile device 100 will fail to perform PING detection on the IP address and port information of the WAN interface 4 of the routing device 200. Therefore, the mobile device 100 S2051-S2052 can be directly executed.

Based on the foregoing description, the mobile device 100 may adopt the following multiple implementation manners to obtain the IP address and port information of the WAN interface 4 of the routing device 200 .

In a feasible implementation manner, since the mobile device 100 has accessed the routing device 200 through the Wi-Fi network 400, the mobile device 100 may request the routing device 200 through the Wi-Fi network 400 for the WAN interface 4 of the routing device 200. The IP address and port information enables the routing device 200 to send the IP address and port information of the WAN interface 4 of the routing device 200 to the mobile device 100 .

In another feasible implementation manner, the mobile device 100 uses the same account as the routing device 200 to log in to the cloud server 800 through an application (Application, App) and/or a web page, so as to obtain the WAN interface 4 of the routing device 200 from the cloud server 800 . IP address and port information.

The cloud server 800 may serve as an information exchange center between the mobile device 100 and the routing device 200 . The cloud server 800 can store the binding information of the routing device 200, such as the ID of the routing device 200, the type of the routing device 200 (such as router or CPE), the MP capability information of the routing device 200, and the IP address of the WAN interface 4 of the routing device 200. and port information, query functions, etc. Generally, the routing device 200 may upload the binding information of the routing device 200 to the cloud server 800 in advance. In addition, when any one of the binding information of the routing device 200 changes, the routing device 200 may update the corresponding information to the cloud server 800 synchronously.

For example, when the mobile phone is connected to the router through the Wi-Fi network 400, the user can bind the mobile phone and the router through an APP or a web page, so that the cloud server 800 provides the binding information of the router to the mobile phone.

In addition, the cloud server 800 may also provide a query interface to the mobile device 100, so as to query whether the routing device 200 supports MP and the like from the query interface. In addition, the cloud server 800 may also transmit the detected service conditions of the application (eg, experience indicators such as delay, bandwidth, or freezing rate) to the mobile device 100, so that the mobile device 100 presents the service conditions of the application. In some embodiments, the mobile device 100 may also display parameters such as the quality of each transmission channel in the MP, the usage traffic of different network types in the MP, and the like.

In another feasible implementation manner, the mobile device 100 uses the Near Field Communication (Near Field Communication, NFC) technology to obtain the IP address and port information of the WAN interface 4 of the routing device 200 by touching the routing device 200.

In another feasible implementation manner, the mobile device 100 can scan the two-dimensional code of the routing device 200 to obtain the IP address and port information of the WAN interface 4 of the routing device 200 .

It should be noted that the present application is not limited to the above four feasible implementation manners so that the mobile device 100 can obtain the IP address and port information of the WAN interface 4 of the routing device 200 .

S2051 , the mobile device acquires the IP address and port information of the gateway of the mobile device based on NAT traversal, and sends the IP address and port information of the gateway of the mobile device to the routing device via the first transmission channel. The routing device acquires the IP address and port information of the gateway of the routing device based on NAT traversal, and sends the IP address and port information of the gateway of the routing device to the mobile device via the first transmission channel.

If the mobile device 100 does not receive the second response from the routing device 200 through the cellular network 500 within a preset period of time, the mobile device 100 may determine that the mobile device 100 cannot access the mobile device 100 based on the IP address and port information of the WAN interface 4 of the mobile device 100 The second transmission channel communicates with the routing device 200, and the routing device 200 cannot sense whether the mobile device 100 sends the second request.

Therefore, the mobile device 100 can use the NAT traversal technology to send NAT traversal data to the cloud server 800 via the gateway 600 of the mobile device 100, so that the cloud server 800 obtains the IP address and port information of the gateway 600 of the mobile device 100. The cloud server 800 sends the IP address and port information of the gateway 600 of the mobile device 100 to the mobile device 100 via the gateway 600 of the mobile device 100 . Therefore, the mobile device 100 sends the IP address and port information of the gateway 600 of the mobile device 100 to the routing device 200 through the Wi-Fi network 400 via the first transmission channel.

In some embodiments, the first MP policy module of the mobile device 100 drives the first NAT module of the mobile device 100 to complete NAT traversal with the cloud server 800, and the first NAT module of the mobile device 100 will store the mobile device when the NAT traversal is successful. IP address and port information of gateway 600 of 100. Therefore, the first MP policy module of the mobile device 100 calls the IP address and port information of the gateway 600 of the mobile device 100 from the first NAT module of the mobile device 100, and drives the MP protocol client module of the mobile device 100 to the routing device 200 The MP protocol server module sends the IP address and port information of the gateway 600 of the mobile device 100 .

When the mobile device 100 acquires the IP address and port information of the gateway 600 of the mobile device 100, the mobile device 100 initiates a NAT traversal request to the routing device 200 through the Wi-Fi network 400 via the first transmission channel, so that the routing device 200 can send a NAT traversal request to the routing device 200 from the cloud. The server 800 acquires the IP address and port information of the gateway 700 of the routing device 200 .

The routing device 200 can use the NAT traversal technology to send NAT traversal data to the cloud server 800 via the gateway 700 of the routing device 200 , so that the cloud server 800 obtains the IP address and port information of the gateway 700 of the routing device 200 . The cloud server 800 sends the IP address and port information of the gateway 700 of the routing device 200 to the routing device 200 via the gateway 700 of the routing device 200 . Thus, the routing device 200 sends the IP address and port information of the gateway 700 of the routing device 200 to the mobile device 100 through the Wi-Fi network 400 via the first transmission channel.

In some embodiments, the first MP policy module of the mobile device 100 drives the MP protocol client module of the mobile device 100 to initiate a NAT traversal request, and the MP protocol client module of the mobile device 100 sends a NAT traversal request to the MP protocol server module of the routing device 200 ask. The MP protocol server module of the routing device 200 forwards the NAT traversal request to the second MP policy module of the routing device 200 .

The second MP policy module of the routing device 200 drives the second NAT module of the routing device 200 to complete NAT traversal with the cloud server 800, and the second NAT module of the routing device 200 will store the IP address of the gateway 700 of the routing device 200 when the NAT traversal is successful address and port information. Therefore, the second MP policy module of the routing device 200 calls the IP address and port information of the gateway 700 of the routing device 200 from the second NAT module of the routing device 200, and drives the MP protocol server module of the routing device 200 to the mobile device 100 The MP protocol client module sends the IP address and port information of the gateway 700 of the routing device 200 .

S2052 , the mobile device 100 and the routing device 200 determine the IP address and port information based on the gateway 600 of the mobile device 100 , the IP address and port information of the gateway 700 of the routing device 200 , and the IP address and port information of the WAN interface 4 of the routing device 200 , transmit data via the second transmission channel.

IP address and port information.

Thus, the mobile device 100 can determine based on the IP address and port information of the gateway 600 of the mobile device 100, the IP address and port information of the gateway 700 of the routing device 200, and the IP address and port information of the WAN interface 4 of the routing device 200, which can be obtained from The WAN interface 2 of the mobile device 100 corresponding to the cellular network 500 transmits data from the WAN interface 4 of the routing device 200 to the routing device 200 via the gateway 600 of the mobile device 100 , the carrier Internet, and the gateway 700 of the routing device 200 .

The routing device 200 can determine the IP address and port information based on the gateway 600 of the mobile device 100, the IP address and port information of the gateway 700 of the routing device 200, and the IP address and port information of the WAN interface 4 of the routing device 200, which can be obtained from the routing device. WAN interface 4 of 200 transmits data from WAN interface 2 of mobile device 100 corresponding to cellular network 500 to mobile device 100 via gateway 700 of routing device 200 , the carrier Internet, and gateway 600 of mobile device 100 .

S206 , the mobile device 100 and the routing device 200 determine to transmit data via the second transmission channel based on the IP address and port information of the WAN interface 4 of the routing device 200 .

If the mobile device 100 receives the second response from the routing device 200 through the cellular network 500 within a preset period of time, the mobile device 100 can determine the IP address and port information of the WAN interface 4 of the routing device 200 based on the second transmission channel. Communicate with routing device 200 . And because the routing device 200 only sends the second response to the mobile device 100 after receiving the second request, the routing device 200 can determine the IP address and port information based on the WAN interface 4 of the routing device 200, and can communicate with the mobile device 100 via the second transmission channel. The mobile device 100 communicates.

Thus, the mobile device 100 can determine the IP address and port information based on the WAN interface 4 of the routing device 200 from the WAN interface 2 of the mobile device 100 corresponding to the cellular network 500, via the gateway 600 of the mobile device 100, the carrier Internet and The gateway 700 of the routing device 200 transmits data from the WAN interface 4 of the routing device 200 to the routing device 200 .

S207. The mobile device sends a third request to the routing device through the cellular network. The third request is a request for establishing a second transmission channel through the cellular network.

In the present application, the mobile device 100 sends a third request to the routing device 200 through the cellular network 500 via the second transmission channel, so as to achieve the purpose of requesting the routing device 200 to establish the second transmission channel.

In some embodiments, the first MP policy module of the mobile device 100 drives the MP protocol client module of the mobile device 100 to send the third request, and the MP protocol client module of the mobile device 100 sends the third request to the MP protocol server module of the routing device 200 .

Wherein, the present application does not limit the specific implementation manner of the third request. In addition, the third request may further include: IP address and port information of the gateway 600 of the mobile device 100

In some embodiments, when the MP protocol client module of the mobile device 100 receives the IP address and port information of the gateway 700 of the routing device 200 from the MP protocol server module of the routing device 200, the first MP policy module of the mobile device 100 drives the The MP protocol client module of the mobile device 100 sends the third request, and the MP protocol client module of the mobile device 100 sends the third request to the MP protocol server module of the routing device 200 .

Wherein, this application does not limit the specific representation of the third request. For example, the third request carries parameters such as IP quintuple, preset network parameters of the application service (such as bandwidth, delay, number of links, etc.), MP capability information of the mobile device 100, and MP communication strategy.

The MP policy is a policy for the mobile device 100 and the routing device 200 to communicate through MP. The MP policy is used to indicate the network type and the number of transmission channels of each transmission channel in the MP, the data packet allocation of each transmission channel in the MP (such as the transmission volume of data packets on each transmission channel), and the number of transmission channels in the MP. The data format of each transmission channel (for example, the form of the encapsulation header used on each transmission channel), etc.

The network type and the number of transmission channels of each transmission channel in the MP comprehensively consider various factors such as network requirements of the service, MP capability information of the mobile device 100 and MP capability information of the routing device 200 . In addition, in general, compared to the cellular network 500, the mobile device 100 will preferentially transmit data on the transmission channel of the Wi-Fi network 400, so as to save the cellular traffic of the user and improve the user experience.

The data packet allocation situation may be configured based on factors such as the protocol type of the MP, the mode type of the MP, and the transmission capability of each transmission channel in the MP, so as to ensure the transmission rate of the data packets. For example, when the protocol type of the MP is the aggregation mode, if the ratio of the transmission capability index of the cellular network 500 to the Wi-Fi network 400 is 1:2, the mobile device 100 can transmit the data packets on the second transmission channel with the data packets on the first transmission channel. The ratio of the number of packets transmitted on a transmission channel is 1:2.

In addition, the transmission capability index ratio may be a bandwidth ratio or a delay ratio, which is not limited in this application. In general, the mobile device 100 often chooses to transmit more data packets on the first transmission channel and transmit fewer data packets on the second transmission channel, which can save the user's cellular traffic and help improve the user's experience.

The data packet format can be determined according to the second transmission channel, which can ensure the accuracy and security of data packet transmission. When the mobile device 100 and the routing device 200 transmit data through the Wi-Fi network 400 , the mobile device 100 and the routing device 200 can transmit data to each other without using the NAT traversal technology. When the mobile device 100 and the routing device 200 transmit data through the cellular network 500 , the mobile device 100 and the routing device 200 may need to use the NAT traversal technology to transmit data to each other. Therefore, the present application can set the format of the data packets on the first transmission channel to be simpler than the format of the data packets on the second transmission channel, so as to save the transmission volume of the data packets and improve the transmission rate of the data packets.

It should be noted that, the communication strategy of the MP is not limited to the above implementation manner.

S208. In response to the third request, the routing device sends a third response to the mobile device through the cellular network. The third response is used to indicate that the routing device has established the second transmission channel with the mobile device through the cellular network.

In this application, the routing device 200 can obtain parameters such as the service type of the application, the MP capability set of the mobile device 100, and the communication strategy of the MP from the third request. The routing device 200 establishes an MP data entry based on parameters such as the service type of the application, the MP capability set of the mobile device 100 and the communication strategy of the MP, thereby establishing the MP between the mobile device 100 and the routing device 200, that is, establishing the second transmission channel . Therefore, when the second transmission channel is established, the routing device 200 can send the third response to the mobile device 100 through the cellular network 500 via the second transmission channel, so that the mobile device 100 can know in time that the routing device 200 has established the second transmission aisle.

Wherein, the MP data table entry includes: the service type of the application (which can be represented in the form of an IP quintuple, that is, an IP triplet + source IP (that is, the IP address of the mobile device 100 ) + source port (that is, the mobile device 100’s IP address) port information)), the MP capability set of the mobile device 100, the MP communication strategy and other parameters. In addition, the present application does not limit the specific implementation manner of the third response.

In some embodiments, the MP protocol server module of the routing device 200 establishes the MP data entry based on the third request, thereby establishing the MP, that is, establishing the second transmission channel. The MP data entry may be stored in the second MP policy module of the routing device 200 . When the second MP policy module of the routing device 200 has established the MP, the second MP policy module of the routing device 200 will start the MP, and notify the second data proxy mode of the routing device 200 based on the IP quintuple of the application service. Data packet rerouting, that is, communication is performed through MP, so that the second data proxy module of the routing device 200 diverts the corresponding data packet to the MP protocol server module of the routing device 200 based on the IP quintuple of the application service.

To sum up, the mobile device 100 and the routing device 200 have established the second transmission channel, thereby facilitating subsequent operations.
