4-1 is a flowchart of a method for establishing a data channel according to an embodiment of the present invention. The method for establishing a data channel is applied to the implementation environment shown in FIG.

Step 401: The terminal generates a virtual IP address.

The virtual IP address is visible to the application layer of the terminal, and the application layer of the terminal can see the virtual IP address, thereby realizing the effect that the data channel is transparent to the application layer. The application layer in the terminal may generate a virtual identity number (abbreviation: ID), and the terminal may use the virtual ID as the virtual IP address of the terminal. This virtual IP address can always be used by the terminal.

For example, the terminal can be a mobile phone, and the mobile phone can be a multi-mode mobile phone. Multi-mode mobile phones refer to networks that can be used in different technical standards, such as Global System For Mobile Communications (GSM) networks and code division multiple access (English: CodeDivisionMultipleAccess; referred to as: CDMA) Mobile phones used between networks, multi-mode phones can reside in multiple networks at the same time. For example, the terminal may be a single user identity supporting a long term evolution (English: Long Term Evolution; LTE for short) network, a second generation mobile communication technology (English: the second generation mobile communication technology; 2G) network, and a 3G network. Identification module (English: Subscriber Identity Module; referred to as: SIM) card multi-mode mobile phone or dual SIM card multi-mode mobile phone.

Step 402: The terminal establishes a connection with each communication network in the n communication networks according to the virtual IP address, where n is greater than or equal to 2.

For example, in a preset network access scenario, each time the terminal is powered on, the terminal can detect n communication networks (ie, wireless access networks) that the terminal can connect through automatic frequency sweeping technology. For example, the communication network may be a wireless local area network, a wireless cellular network, a wireless private network, a ZigBee network, and a low-power wireless personal area network based on the Internet Protocol version 6. (English: Internet Protocol Version 6 over Low- The power wireless personal area network (abbreviation: 6LowPAN) and the like, the embodiment of the present invention does not limit the network form of the communication network. In the prior art, the terminal includes a packet switching (English: Packet Switch; PS) domain and a circuit switching (English: Circuit Switch; CS: abbreviation: CS) domain, where the PS domain is mainly responsible for session control related to the packet type service. For mobility management and other functions, the PS domain is mainly used for data transmission; the CS domain is mainly responsible for call control and mobility management functions related to circuit-type services, and the CS domain is mainly used for voice calls. The embodiment of the present invention can solve the problem of communication delay and data loss in the PS domain data packet transmission process, and the embodiment of the present invention can be applied to various scenarios involving PS domain data transmission.

Specifically, as shown in FIG. 4-2, step 402 may include:

Step 4021: Send a connection request message to a packet gateway of each communication network in the n communication networks according to the virtual IP address.

The connection request message includes a virtual IP address. The terminal sends a connection request message to the packet gateway of each communication network in the n communication networks according to the virtual IP address. For example, if the n communication networks are respectively a 2G network, a 3G network, and a 4G network, the terminal according to the virtual IP address The packet gateway of the 2G network sends a connection establishment request, and the terminal sends a connection request message to the packet gateway of the 3G network according to the virtual IP address, and the terminal sends a connection request message to the packet gateway of the 4G network according to the virtual IP address.

Step 4022: Receive a connection response message sent by a packet gateway of each communication network, where each connection response message includes an IP address allocated by the communication network for the terminal.

The terminal sends a connection to the packet gateway of each communication network in the n communication networks according to the virtual IP address. After receiving the request message, a connection response message sent by the packet gateway of each communication network is received. Taking the 2G network, the 3G network, and the 4G network in step 4021 as an example, the terminal sends a connection establishment request to the packet gateway of the 2G network according to the virtual IP address, and the packet gateway of the 2G network sends a connection response message to the terminal, where the connection response message includes The IP address assigned by the 2G network to the terminal. The terminal sends a connection establishment request to the packet gateway of the 3G network according to the virtual IP address, and the packet gateway of the 3G network sends a connection response message to the terminal, where the connection response message includes an IP address allocated by the 3G network for the terminal. The terminal sends a connection establishment request to the packet gateway of the 4G network according to the virtual IP address, and the packet gateway of the 4G network sends a connection response message to the terminal, where the connection response message includes an IP address allocated by the 4G network for the terminal. Finally, the terminal is attached to 2G networks, 3G networks, and 4G networks. In addition, each connection response message may further include a port number assigned by the communication network to the terminal, the port number being a number of a port for distinguishing the service.

Step 403: The terminal acquires an IP address allocated by each communication network in the n communication networks for the terminal, and obtains n IP addresses.

The n IP addresses are invisible to the application layer of the terminal, so that the application layer cannot perceive the change of the underlying IP address, thereby realizing the effect of shielding different data channels from the application layer software. After the terminal establishes a connection with each communication network in the n communication networks according to the virtual IP address, the terminal can obtain an IP address assigned to the terminal by each communication network in the n communication networks, and the terminal acquires the IP address and registers with the corresponding communication network. in. At the same time, the terminal can also obtain the port number assigned by the communication network to the terminal. Taking the 2G network, the 3G network, and the 4G network in step 4022 as an example, the terminal acquires an IP address assigned to the terminal by each communication network in the three communication networks, and obtains three IP addresses.

Step 404: The terminal establishes a first IP resource pool according to the n IP addresses.

The first IP resource pool includes n IP addresses. Optionally, the terminal may establish a first IP resource pool according to the n addresses obtained in step 403. The first IP resource pool includes an IP address assigned to the terminal by each of the n communication networks to which the terminal is connected. In addition, the first IP resource pool may further include a port number assigned to the terminal by each communication network.

Optionally, the terminal may set a virtual internet protocol proxy (English: Virtual Internet Protocol Proxy; referred to as: VIPP) module, and the terminal may establish a first IP resource pool according to n IP addresses through the VIPP module. 4-3 shows a schematic structural diagram of a terminal provided with a VIPP module. In FIG. 4-3, n communication networks connected to the terminal are respectively a communication network 1, a communication network 2, a communication network 3, ..... The communication network n, n communication networks assigned IP addresses for the terminals are IP1, IP2, IP3, ..., IPn. According to steps 401 to 404, the application layer of the terminal generates a virtual IP address. The VIPP module uses the virtual ID as a virtual IP address. After the terminal is powered on, the VIPP module can automatically scan the communication network that the terminal can connect, and control the terminal to establish a connection with each communication network in the n communication networks according to the virtual IP address, and the VIPP module acquires each communication network in the n communication networks as the terminal. The assigned IP address obtains n IP addresses, and then establishes a first IP resource pool according to n IP addresses.

Step 405: The terminal sends the virtual IP address and the information of the first IP resource pool to the server.

Optionally, after the terminal establishes the first IP resource pool according to the n IP addresses, the terminal may send the virtual IP address and the information of the first IP resource pool to the server, so that the server establishes the information according to the virtual IP address and the information of the first IP resource pool. The second IP resource pool of the terminal indicated by the virtual IP address.

For example, the terminal may send the virtual IP address and the information of the first IP resource pool to the server through the VIPP module shown in FIG. 4-3. Similarly, the server can set a virtual link control (English: Virtual Internet Protocol Control; referred to as: VIPC) module, and Figure 4-4 shows the structure of the server with the VIPC module. In Figure 4-4, the n communication networks connected to the server are respectively a communication network 1, a communication network 2, a communication network 3, ..., a communication network n. After the terminal establishes the first IP resource pool according to the n IP addresses, the terminal can automatically send the transmission control protocol to the VIPC module shown in Figure 4-4 (English: Transmission Control Protocol; TCP). A link setup request establishes a TCP link. After the TCP link is established, the VIPP module sends the virtual IP address and the information of the first IP resource pool to the VIPC module through the established TCP link. As shown in Figure 4-4, the n IP addresses in the first IP resource pool can be centrally stored in the IP module.

Step 406: The server establishes a second IP resource pool of the terminal indicated by the virtual IP address according to the virtual IP address and the information of the first IP resource pool.

The second resource pool includes n IP addresses. Optionally, after receiving the virtual IP address sent by the terminal and the information of the first IP resource pool, the server may establish a second IP resource pool of the terminal indicated by the virtual IP address according to the virtual IP address and the information of the first IP resource pool. . The second IP resource pool may also include a port number assigned to the terminal by each communication network. For example, the server may establish a second IP resource pool according to the virtual IP address and the information of the first IP resource pool by using the VIPC module shown in FIG. 4-4. The information of the second IP resource pool is the same as the information of the first IP resource pool. The VIPC module can establish its own IP resource pool according to the information of the first IP resource pool sent by the VIPP module, and maintain the information of the IP resource pool.

Step 407: The terminal establishes a data channel with the server by using each of the n IP addresses.

Specifically, the terminal establishes a data channel with the server by using each of the n IP addresses, including: the terminal separately sends a channel to the server according to each of the n IP addresses. Request; the terminal receiving server establishes a response based on the channel respectively sent by each of the n IP addresses. Taking the 2G network, the 3G network, and the 4G network in step 4022 as an example, the terminal acquires an IP address assigned to each terminal in each of the three communication networks, obtains three IP addresses, and then uses each of the three IP addresses. Each IP address establishes a data channel with the server. Assuming that the three IP addresses are IPa, IPb, and IPc, the terminal can establish three data channels with the server by using IPa, IPb, and IPc. Compared with the prior art, the terminal and the server are used to transmit the data channel of the data packet. More numbers increase the reliability of packet transmission. For the process of establishing a data channel with the server by using each of the n IP addresses, the terminal may refer to the prior art, and details are not described herein.

It should be added that the VIPP module in Figure 4-3 can manage multiple data channels upwards and shield different data channels for the application layer. The VIPC module in Figure 4-4 functions similarly to the VIPP module. Manage the underlying multiple data channels down and shield different data channels for the business layer.

The terminal establishes a data channel with the server by using each of the n IP addresses, and the server establishes a data channel with the terminal by using each of the n IP addresses. The server may establish a data channel with the terminal by using the n IP addresses in the first IP resource pool sent by the terminal, or establish a data channel with the terminal by using the n IP addresses in the established second IP resource pool.

Step 408: The terminal determines a quality of service of each of the n data channels.

The terminal can measure and record the quality of service of each data channel in real time through the VIPP module shown in Figure 4-3 (English: Quality of Service; QoS for short). The service quality of the data channel may be the signal-to-noise ratio of the uplink and downlink channels of the data channel (English: Signal-Noise Ratio; SNR), number of data packet retransmissions, number of channel carriers, channel bandwidth, channel delay, channel type. The specific form of the service quality is not limited in the embodiment of the present invention. For example, the higher the signal-to-noise ratio, the better the quality of the data channel. The smaller the number of packet retransmissions, the better the quality of the data channel. In addition, the VIPP module can also comprehensively consider a plurality of parameters to calculate the service quality of the data channel. For the specific calculation process, reference may be made to the prior art, and details are not described herein again.

Step 409: The terminal sorts the n data channels according to the service quality of each of the n data channels to obtain the sorting information.

Optionally, the terminal can sort the n data channels according to the service quality of each data channel in the n data channels by using the VIPP module shown in Figure 4-3 to obtain sorting information. Assume that in step 407, the data channel established by the terminal using IPa and the server is PS channel A, and the terminal utilizes IPb and service. The data channel established by the device is PS channel B, and the data channel established by the terminal using IPc and the server is PS channel C. If the quality of service of the data channel is represented by a number, the larger the number, the better the quality of service of the data channel. If the quality of service of PS channel A is 2, the quality of service of PS channel B is 3, and the quality of service of PS channel C is 4, the VIPP module sorts the data channels according to the service quality of the data channel from good to bad, and obtains: PS channel C, PS channel B and PS channel A.

Step 410: The terminal records the quality of service and the sorting information of each of the n data channels to the first IP resource pool.

Optionally, the VIPP module shown in Figure 4-3 records the quality of service and the sorting information of each of the n data channels to the first IP resource pool. Taking PS channel A, PS channel B and PS channel C in step 409 as an example, the VIPP module can provide the quality of service of PS channel A: 2, the quality of service of PS channel B: 3, the quality of service of PS channel C: 4, And sorting information: PS channel C, PS channel B, and PS channel A are recorded in the first IP resource pool. Since the information of the second IP resource pool is the same as the information of the first IP resource pool, the second IP resource pool may further include a quality of service of each of the n data channels and a quality of service of the n data channels. information.

Step 411: The terminal detects whether an interruption occurs in the first data channel.

The first data channel is any one of the n data channels. For example, the terminal can detect whether the data channel is interrupted by using the VIPP module shown in Figure 4-3.

Step 412: When the first data channel is interrupted, the terminal sets the information corresponding to the first data channel in the first IP resource pool to a prohibited use state.

When the terminal detects that there is a data channel interruption through the VIPP module shown in Figure 4-3, the terminal can set the information corresponding to the data channel in the first IP resource pool, such as the IP address of the data channel, through the VIPP module. The use of the state is prohibited, so that the data channel with poor service quality can be eliminated in time, and the data channel with better quality of service is selected for data packet transmission. The terminal sets the information corresponding to the first data channel in the first IP resource pool to the forbidden state, that is, the terminal sets the information corresponding to the first communication channel in the first IP resource pool, such as the IP address corresponding to the first data channel, to be unavailable. For example, after the information corresponding to the first data channel is set to be unavailable, the terminal cannot transmit the data packet through the first data channel. It should be added that, in addition to setting the information corresponding to the data channel in which the interruption occurs to the prohibited use state, other information corresponding to the data channel that does not satisfy the transmission requirement may be set to the prohibited use state, for example, the service quality is less than a certain value. The information corresponding to the data channel is set to the prohibited use state.

It should be noted that the sequence of steps of the data channel establishment method provided by the embodiment of the present invention may be In order to make appropriate adjustments, the steps may also be correspondingly increased or decreased according to the situation, and any method that can be easily conceived within the technical scope of the present invention by any person skilled in the art should be covered by the scope of the present invention. Therefore, I will not repeat them.

In summary, in the data channel establishment method provided by the embodiment of the present invention, the terminal can establish a connection with each communication network in the n communication networks according to the virtual IP address, and acquire each communication network in the n communication networks for the terminal. IP address, get n IP addresses, and then use each of the n IP addresses to establish a data channel with the server. The server can establish a virtual IP address according to the virtual IP address sent by the terminal and the information of the first IP resource pool. The second IP resource pool of the indicated terminal, and each of the n IP addresses respectively establishes a data channel with the terminal, and the number of data channels used by the terminal and the server to transmit the data packet is compared with the prior art. More, therefore, improves the reliability of packet transmission.

FIG. 7-1 is a flowchart of a data packet transmission method according to an embodiment of the present invention. The data packet transmission method may be applied to the implementation environment shown in FIG.

Step 701: The terminal generates a virtual IP address.

The specific process of step 701 can be described with reference to step 401.

Step 702: The terminal establishes a connection with each of the n communication networks according to the virtual IP address.

Step 703: The terminal acquires an IP address assigned by each communication network in the n communication networks to the terminal.

The specific process of step 703 can be described with reference to step 403.

Step 704: The terminal establishes a first IP resource pool.

The first IP resource pool includes n IP addresses. The specific process of step 704 can be described with reference to step 404.

Step 705: The terminal determines a quality of service of each of the n data channels.

Optionally, the first IP resource pool further includes the service quality of the data channel of each communication network in the n communication networks and the ranking information of the service quality of the n data channels. The specific process of step 705 can be described with reference to step 408.

Step 706: The terminal sorts the n data channels according to the service quality of each of the n data channels to obtain the sorting information.

The specific process of step 706 can be described with reference to step 409.

Step 707: The terminal records the quality of service and the sorting information of each of the n data channels to the first IP resource pool.

The specific process of step 707 can be described with reference to step 410.

In a possible implementation manner, the terminal updates the service quality and the sorting information of each data channel in the first IP resource pool every preset time period, and the terminal accesses the first IP resource pool every preset time period. The information is updated, and the data channel with better service quality can be selected in time for data packet transmission, thereby further improving the reliability of data packet transmission. For example, the terminal may update the information of the first IP resource pool through the VIPP module shown in Figure 4-3. Taking PS channel A, PS channel B, and PS channel C in step 410 as an example, assume that the current time, the VIPP module detects that the quality of service of PS channel A is 2, the quality of service of PS channel B is 3, and the service of PS channel C. The quality is 4, after the preset time period, the VIPP module detects that the service quality of PS channel A is 3, the service quality of PS channel B is 4, and the service quality of PS channel C is 2, then the VIPP module can access the first IP resource. The original quality of service of the three data channels in the pool is updated, that is, the quality of service of PS channel A is updated from 2 to 3, the quality of service of PS channel B is updated from 3 to 4, and the quality of service of PS channel C is updated by 4. 2, and reordering the 3 data channels according to the quality of service from good to bad, obtaining: PS channel B, PS channel A and PS channel C.

Step 708: The terminal detects whether an interruption occurs in the first data channel.

The first data channel is any one of n data channels. The specific process of step 708 can be described with reference to step 411.

Step 709: When the first data channel is interrupted, the terminal sets the information corresponding to the first data channel in the first IP resource pool to a prohibited use state.

The specific process of step 709 can be described with reference to step 412.

Step 710: The terminal sends the virtual IP address and the information of the first IP resource pool to the server.

The specific process of step 710 can be described with reference to step 405.

Step 711: The server establishes a second IP resource pool of the terminal indicated by the virtual IP address according to the virtual IP address and the information of the first IP resource pool.

The second resource pool includes n IP addresses. The second IP resource pool further includes ranking information of the quality of service of the data channel of each of the n communication networks and the quality of service of the n data channels. The specific process of step 711 can be described with reference to step 406.

Step 712: When the information of the first IP resource pool changes, the terminal sends the changed information of the first IP resource pool to the server.

In a possible implementation, after the terminal sends the virtual IP address and the information of the first IP resource pool to the server, when the information of the first IP resource pool changes, the terminal may change the first IP resource pool. The information is sent to the server, so that the server updates the second IP resource pool according to the changed information of the first IP resource pool, so that the server can select a data channel with better quality of service for data packet transmission. For example, the terminal can send the changed information of the first IP resource pool to the VIPC module of the server through the VIPP module shown in Figure 4-3. The VIPC module is the VIPC module shown in Figure 4-4.

For example, when the first data channel in the first IP resource pool is set to be in the forbidden state, the information of the changed first IP resource pool may be changed. Sending to the server, so that the server sets the information corresponding to the first data channel in the second IP resource pool to the prohibited use state.

Step 713: The server updates the second IP resource pool according to the changed information of the first IP resource pool.

For example, the server may update the second IP resource pool according to the changed information of the first IP resource pool by using the VIPC module shown in FIG. 4-4.

Step 714: When the data packet transmission needs to be performed, the terminal acquires the first IP address in the first IP resource pool.

The first IP address is the target source IP address used for packet transmission. The data packet includes data to be transmitted, a first source IP address, and a first destination IP address, the first source IP address is a virtual IP address of the terminal, and the first destination IP address is an IP address of the server. The number of the first IP address obtained by the terminal in the first IP resource pool may be equal to 1 or greater than 1. For example, the terminal can obtain the first IP address in the first IP resource pool through the VIPP module shown in Figure 4-3.

Optionally, in an aspect, step 714 may include: using the n IP addresses in the first IP resource pool as the first IP address.

For example, the VIPP module shown in Figure 4-3 can have data channel selection capability. The VIPP module can use the n IP addresses in the first IP resource pool together as the first IP address for data packet transmission. In this way, the terminal transmits data packets to the server through n data channels, and the n data channels form a link hot backup, which greatly improves the reliability of data packet transmission.

On the other hand, the data packet further includes: a type of data to be transmitted, and correspondingly, as shown in FIG. 7-2, step 714 may include:

Step 7141: Determine an important level of data to be transmitted according to the type of data to be transmitted.

It is assumed that the embodiment of the present invention is applied to a wireless power communication system, and the data of the wireless power communication system is classified into key data, important data, general data, and file type data according to the type, and the important level of the key data is higher than the important level of the important data, and the important data. The important level is higher than the important level of the general data, and the important level of the general data is higher than the important level of the file type data. When the type of the data to be transmitted is key data, it may be determined that the importance level of the data to be transmitted is the highest; when the type of the data to be transmitted is file type data, it may be determined that the important level of the data to be transmitted is the lowest. For example, for critical data and important data, the terminal can select one or more data channels with better quality of service to transmit data packets through the VIPP module; for general data and file type data, if the data channel with better quality of service is in the data channel Working status, the terminal can select a data channel with a poor quality of service to transmit data packets through the VIPP module.

Step 7142: Determine m data channels in the n data channels according to the importance level of the data to be transmitted, the quality of service and the sorting information of each data channel in the n data channels, where m is greater than or equal to 1, and less than n.

Assuming that the type of data to be transmitted is critical data, since the critical data has the highest importance level, it is necessary to select a data channel with better quality of service to transmit the data packet. Taking PS channel A, PS channel B, and PS channel C in step 410 as an example, assume that the quality of service of PS channel A is 2, the quality of service of PS channel B is 3, and the quality of service of PS channel C is 4, and the VIPP module is The three data channels are sorted according to the quality of the data channel from good to bad, and PS channel C, PS channel B and PS channel A are obtained. Then, the VIPP module can select the data channel with better quality of service according to two strategies. The first strategy is: the VIPP module selects the PS channel C transmission data packet located in the first name; the second strategy is: the VIPP module selects the first two PS channel C and PS channel B transmission data packets. It should be added that in the second strategy, the VIPP module can first select the first two PS channels C and PS channel B, according to the preset threshold and the quality of service of the selected PS channel C and the quality of service of the PS channel B, further screening the PS channel C and the PS channel B, such as selecting data with a service quality greater than a preset threshold. The channel transmits data packets, excluding data channels whose quality of service is less than a preset threshold.

Step 7143: The IP address assigned by the communication network corresponding to each data channel of the m data channels is the first IP address.

Assuming that n in step 7142 is equal to 10, m is equal to 3, and three data channels are determined according to step 7142, then the terminal can use the VIPP module to assign the IP address corresponding to the communication network corresponding to each of the three data channels to the terminal as the IP address of the terminal. First IP address.

Step 715: The terminal replaces the first source IP address of the data packet with the virtual IP address and the first IP address, and obtains the processed data packet.

For example, the terminal can replace the first source IP address of the data packet with the virtual IP address by using the VIPP module shown in FIG. 4-3. The VIPP module provides a TCP/IP protocol interface for the application layer. The VIPP module can convert the application layer TCP/IP interface call into a call to the underlying first IP resource pool to shield different data channels from the application layer. The difference. Assuming that m is equal to 1 in step 7143, the IP address corresponding to the communication network corresponding to the data channel is IPA, and the terminal uses IPA as the first IP address. Then, according to step 715, the terminal uses the first source in the data packet through the VIPP module. The IP address is replaced by the virtual IP address to IPA, and the processed data packet is obtained. In the process, the VIPP module replaces the command of the application layer transmission packet: (first source IP address: virtual IP address of the terminal, first destination IP address: IP address of the server) with a new command: (first source) IP address: IPA, first destination IP address: IP address of the server), to achieve mapping of data channels.

Step 716: The terminal transmits the processed data packet to the server by using a data channel of the communication network indicated by the first IP address and the first destination IP address.

After processing the address information in the data packet to be transmitted, the terminal transmits the processed data packet to the server.

It should be added that when the data channel for transmitting the data packet is interrupted, the data channel needs to be switched, or when the service quality of the data channel for transmitting the data packet is poor, and the data channel needs to be switched. The terminal can directly process the address information in the data packet through the VIPP module, replace the first IP address with another IP address that satisfies the transmission requirement, and then communicate the communication indicated by the IP address satisfying the transmission requirement and the IP address of the server. The data channel of the network transmits the processed data packet to the server. Throughout the process, the terminal does not need to initiate a wireless connection request to another communication network, which solves the problem of communication delay and data loss caused by interruption of data packet transmission in the prior art.

Step 717: When data packet transmission is required, the server acquires the second IP address in the second IP resource pool.

The second IP address is a target destination IP address used for data packet transmission, and the data packet includes data to be transmitted, a second source IP address, and a second destination IP address, and the second source IP address is an IP address of the server, and the second destination The IP address is a virtual IP address.

For example, the server may use the VIP IP address shown in FIG. 4-4 to use the n IP addresses in the second IP resource pool as the second IP address; the server may also determine the second level according to the importance level of the data to be transmitted through the VIPC module. IP address. Specifically, as shown in FIG. 7-3, step 717 may include:

Step 7171: Determine an important level of data to be transmitted according to the type of data to be transmitted.

The data packet also includes the type of data to be transmitted. The server can determine the importance level of the data to be transmitted according to the type of data to be transmitted included in the data packet. The specific process of step 7171 can be described with reference to step 7141.

Step 7172: Determine p data channels in the n data channels according to the importance level of the data to be transmitted, the quality of service and the sorting information of each data channel in the n data channels, where p is greater than or equal to 1, and less than n.

The specific process of step 7172 can be described with reference to step 7142.

Step 7173: The IP address assigned to the terminal by the communication network corresponding to each of the p data channels is used as the second IP address.

Assuming that n in step 7172 is equal to 10, p is equal to 4, and four data channels are determined according to step 7172, then the server can use the VIPC module to assign the IP address corresponding to the communication network corresponding to each of the four data channels to the terminal as the IP address of the terminal. Second IP address. The specific process for the server to obtain the second IP address in the second IP resource pool may be described with reference to step 714.

Step 718: The server replaces the second destination IP address of the data packet with the virtual IP address and the second IP address, and obtains the processed data packet.

For example, the server can replace the second destination IP address of the data packet from the virtual IP address to the second IP address through the VIPC module shown in FIG. 4-4. The VIPC module provides a TCP/IP protocol interface for the service layer. The VIPC module can convert the TCP/IP interface call of the service layer into a call to the underlying second IP resource pool to shield different data channels from the software of the service layer. The difference. Assuming that p is equal to 1 in step 7173, the IP address corresponding to the communication network corresponding to the data channel is IPE, and the server uses the IPE as the second IP address. Then, according to step 718, the server uses the VIPC module to set the second destination in the data packet. The IP address is replaced by a virtual IP address with an IPE. In the process, the VIPC module will The command to transmit the data packet at the service layer: (the second source IP address: the IP address of the server, the second destination IP address: the virtual IP address of the terminal) is replaced with a new command: (second source IP address: IP address of the server) , the second destination IP address: IPE), to achieve the mapping of the data channel.

Step 719: The server transmits the processed data packet to the terminal by using a data channel of the communication network indicated by the second source IP address and the second IP address.

After processing the address information in the data packet to be transmitted, the server transmits the processed data packet to the terminal.

It should be added that when the data channel for transmitting the data packet is interrupted, the data channel needs to be switched, or when the service quality of the data channel for transmitting the data packet is poor, and the data channel needs to be switched. The server can directly process the address information in the data packet through the VIPC module, replace the second IP address with another IP address that satisfies the transmission requirement, and then indicate by the second source IP address and the IP address satisfying the transmission requirement. The data channel of the communication network transmits the processed data packet to the terminal. This process solves the problem of communication delay and data loss caused by interruption of data packet transmission in the prior art.

FIG. 7-4 shows a startup flowchart of a terminal in the prior art. The terminal may be a single SIM multimode dual standby terminal, and the terminal supports an access process of a 4G network. As shown in Figure 7-4, when the terminal is powered on, the terminal preferentially searches for the 4G network. If the 4G network is available, the terminal resides on the 4G network, and the terminal sends a PS domain registration request message to the 4G network. The 4G network according to the PS domain. The registration request sends a PS domain registration accept message and a PS domain registration completion message to the terminal, and the 4G network assigns an IP address to the terminal, and the terminal performs data packet transmission. At the same time, the terminal initiates a CS domain registration request message of the 3G network, and the 3G network sends a CS domain registration accept message and a CS domain registration complete message to the terminal according to the CS domain registration request message. The terminal successfully registers with the 3G network and makes voice calls over the 3G network. After the terminal's boot process is completed, it can enter the dual standby state.

7-5 are flowcharts showing the network switching of the terminal in FIG. 7-4. As shown in Figure 7-5, the terminal transmits data packets through the 4G network. When the terminal detects that the data channel (PS channel) of the 4G network is interrupted, the terminal initiates a PS domain registration request to the 3G network. After the PS domain is successfully registered, The 3G network allocates a new IP address to the terminal, and the terminal reconstructs and recovers the PS domain data on the 3G network. When the terminal detects that the data channel of the 3G network is interrupted, the terminal searches for the 4G network and resides on the 4G network, and the terminal resends the PS domain registration request message to the 4G network. After the PS domain is successfully registered, the 4G network allocates the terminal to the terminal. A new IP address and bearer resources, the terminal rebuilds and recovers the PS domain data on the 4G network, and the 3G network and the terminal release the connection related to the 3G network and Host resources. The CS domain of the terminal is in the standby state during the handover.

7-6 are schematic diagrams showing the model involved in a data packet transmission method in the prior art. As shown in Figure 7-6, the terminal can only transmit through one communication network (ie, communication network 1, communication network 2, communication network 3, ..., one of the communication networks n) at the same time. The data packet, FIG. 7-6 shows that the terminal transmits the data packet through the communication network 1 at the current time, and therefore, the reliability of the data packet transmission is low; when the terminal performs the network switching, the current bearer link needs to be interrupted, and the other communication is performed. The network initiates a wireless connection request, acquires a new IP address, and the data packet transmission is interrupted, resulting in communication delay and data loss, and the reliability of data packet transmission is low; n IP addresses (ie, IP1, IP2, IP3, .... .., IPn) is visible to the application layer of the terminal. The application layer of the terminal needs to manage the switching process of the underlying data channel, and the development complexity of the application layer is high. At the same time, n IP addresses are also visible to the service layer of the server, and the service of the server is The layer needs to manage the underlying data channel, and the development complexity of the business layer is high. In Figure 7-6, the IP addresses of the underlying multiple data channels in the server are stored centrally in the IP module.

As shown in FIG. 7-7, a terminal is provided with a VIPP module, and a server is provided with a VIPC module, and the terminal can pass multiple times at the same time. Communication networks (ie, communication network 1, communication network 2, communication network 3, ..., communication network n) transmit data packets, which improves the reliability of data packet transmission; when the terminal performs network switching, it is not necessary to Another communication network initiates a wireless connection request to acquire a new IP address, which solves the problem of communication delay and data loss caused by interruption of data packet transmission, and improves the reliability of data packet transmission; n IP addresses (ie, IP1, IP2, IP3) , ..., IPn) is invisible to the application layer of the terminal. The application layer of the terminal does not need to manage the switching process of the underlying data channel, which reduces the development complexity of the application layer, and the n IP addresses also serve the server. The layer is not visible, and the server's business layer does not need to manage the underlying data channel, which reduces the development complexity of the business layer.

Among them, the channel type can be 2G, 3G, 4G, wireless fidelity (English: WIreless-Fidelity; referred to as: WIFI) and private network LTE and so on. The VIPP module in the method can measure the service quality of the data channel in real time, and perceive the service to achieve the best matching of the data channel and the data requirement. For example, for the highest priority data, the VIPP module can distribute the corresponding data packets to multiple data channels for simultaneous transmission, improving the reliability of data packet transmission. For data with low reliability requirements, the VIPP module can allocate corresponding data packets. Transmission to a data channel with poor quality of service, thus improving the reliability of data packet transmission and ensuring the quality of the service. The method solves the problem of communication delay and data loss caused by interruption of data packet transmission, avoids the influence of channel interference and data channel service quality degradation on communication quality. For example, the data packet transmission method enables wireless communication technology to be applied. In the field of power control where high reliability is required.

The information of the second IP resource pool is the same as the information of the first IP resource pool. The VIPP module of the dual SIM card multimode terminal can update the service quality and the sorting information of each data channel in the first IP resource pool every preset time period.

The VIPP module of the dual SIM card multimode terminal can also detect whether there is an interruption of the data channel, or whether the service quality of the data channel is less than a certain value, when there is a data channel interruption, or when the service quality of the data channel is less than a certain value, The VIPP module sets the information corresponding to the data channel in the first IP resource pool to a prohibited state.
