Fig. 4b is a schematic diagram of a communication connection exemplarily shown.

Referring to Fig. 4b, for example, after the SIM2 card in the 5G mobile phone case is activated, a cellular network card 2 can be created in the 5G mobile phone case.

Exemplarily, after the SIM2 card in the 5G mobile phone case is activated, the multi-stream concurrent application program in the 4G mobile phone can use its own cellular data path and the cellular data path of the 5G mobile phone case to perform data interaction with the corresponding service server in parallel . Among them, the application program that supports multi-stream concurrency can refer to the application program that can establish multiple TCP/IP (Transmission Control Protocol/Internet Protocol, Transmission Control Protocol/Internet Protocol) connections in parallel, such as video applications, game applications, live broadcast applications, etc. wait. In this embodiment of the present application, an APP (Application, application program) 2 in a 4G mobile phone is taken as an example for description.

Fig. 5a is an exemplary connection diagram.

Referring to Figure 5a, for example, when APP2 needs to perform data interaction with the business server, it can first establish multiple TCP/IP connections with the business server, and then APP2 performs data interaction with the business server based on the established multiple TCP/IP connections . Exemplarily, the embodiment of the present application does not limit the number of TCP/IP connections established between APP2 and the service server, and the embodiment of the present application takes the establishment of two TCP/IP connections as an example for illustration.

Exemplarily, the process of establishing a TCP/IP connection between APP2 and the service server is essentially the process of establishing a socket (socket) connection between APP2 and the service server.

Fig. 5b is a schematic diagram of a communication connection exemplarily shown.

Referring to FIG. 5b(1), for example, APP2 can establish a socket1 connection with the service server through the cellular network card 1 and Modem1 in the 4G mobile phone. Referring to Fig. 5b(2), exemplary, the socket1 connection is a data path between APP2-cellular network card 1-Modem1-service server. It can be seen that the socket1 connection is essentially a TCP/IP connection between APP2 and the service server.

Exemplarily, the source IP address of the socket1 connection is the IP address of the cellular network card 1, and the destination IP address is the IP address of the service server. For example, the IP address of the cellular network card 1 is a.b.c.d, and the IP address of the service server is E.F.G.H, then the source IP address of the socket1 connection is a.b.c.d, and the destination IP address is E.F.G.H.

Referring to Figure 5b(1), for example, APP2 can use the USB network card 1 in the 4G mobile phone, the USB network card 2 in the 5G mobile phone case, the network proxy service in the 5G mobile phone case, the cellular network card 2 in the 5G mobile phone case and the 5G Modem2 in the mobile phone case establishes a socket2 connection with the service server. Referring to FIG. 5b(3), for example, the socket2 connection may include a socket2a connection and a socket2b connection. Among them, the socket2a connection is created by APP2, which is the data path between APP2—USB network card 1—USB network card 2—network proxy service. The socket2b connection is created based on the socket2a connection trigger, and is the data path between the network proxy service-cellular network card 2-Modem2-business server. It can be seen that the socket2a connection and socket2b connection form another TCP/IP connection between APP2 and the business server.

Exemplarily, the source IP address of the socket2a connection is the IP address of the USB network card 1, and the destination IP address is the IP address of the service server. For example, the IP address of USB network card 1 is w.x.y.z, the IP address of the service server is E.F.G.H, then the source IP address of socket2a connection is w.x.y.z, and the destination IP address is E.F.G.H.

Exemplarily, the source IP address of the socket2b connection is the IP address of the cellular network card 2, and the destination IP address is the IP address of the service server. For example, the IP address of the cellular network card 2 is A.B.C.D, and the IP address of the service server is E.F.G.H, then the source IP address of socket2b is A.B.C.D, and the destination IP address is E.F.G.H.

Exemplarily, APP2 may establish a socket connection with the service server by performing a three-way handshake with the service server. Wherein, the process of establishing the socket1 connection between APP2 and the service server can refer to the provisions in the existing protocol for details, and will not be repeated here. The process of establishing the socket2 connection between APP2 and the service server is described as an example below.

Fig. 6a is a schematic diagram of data transmission exemplarily shown.

Exemplarily, APP2 first sends a SYN (synchronize, synchronization) packet to the service server, and performs a first handshake with the service server. Referring to Fig. 6a, for example, the source data sent by APP2 is a SYN packet. Exemplarily, after APP2 sends out the SYN packet, the SYN packet is added with a TCP header and an IP header, and is transmitted to the USB network card 1 . Wherein, for the convenience of subsequent description, the SYN packet with the IP header and the TCP header added can be called data A1, and the IP header added to the SYN packet can be called IP header (1), and the added TCP header will be called “A1” for SYN. is the TCP header (1).

Exemplarily, the TCP header (1) may include a source port and a destination port, the source port is the port bound to the socket2a connection in the 4G mobile phone, such as PROT1, and the destination port is the port bound to the socket2 connection in the service server, such as PROT16. The IP header (1) includes a source IP address and a destination IP address, the source IP address is the IP address of the USB network card 1 such as w.x.y.z, and the destination IP address is the IP address of the service server such as E.F.G.H.

Exemplarily, between the 4G mobile phone and the 5G mobile phone case, the TCP/IP protocol or UDP/IP (User Datagram Protocol Internet Protocol, User Datagram Protocol/Internet Protocol) protocol is used for communication through the USB data cable. That is to say, the USB connection may be a TCP/IP connection or a UDP/IP connection, which is not limited in this embodiment of the present application. In the embodiment of the present application, the USB connection between the 4G mobile phone and the 5G mobile phone case is an example of a TCP/IP connection for illustration.

Continuing to refer to FIG. 6a, after the USB network card 1 receives the data A1, it can encapsulate the corresponding TCP header (2) and IP header (2) for the data A1 according to the TCP/IP protocol between the USB network card 1 and the USB network card 2, Get data A2.

Exemplarily, the TCP header (2) may also include a source port and a destination port, the source port is the port used for communicating with the USB network card 2 in the USB network card 1, and the destination port is used for communicating with the USB network card 1 in the USB network card 2 port. The IP header (2) also includes a source IP address and a destination IP address, the source IP address is the IP address of the USB network card 1, and the destination IP address is the IP address of the USB network card 2.

Exemplarily, after the USB network card 1 encapsulates and obtains the data A2, the data A2 may be sent to the USB network card 2 based on the connection between the USB network card 1 and the USB network card 2 .

Exemplarily, the USB network card 2 can receive the data A2, and then can decapsulate the data A2, remove the IP header (2) and the TCP header (2) of the data A2, and obtain the data A3. Among them, data A3 is substantially data A1.

Exemplarily, the USB network card 2 can send the data A3 to the network proxy service. After the network proxy service receives the data A3, it can perform NAT conversion on the data A3 to obtain the data A4. Among them, performing NAT conversion on data A3 is to convert the source IP address in IP header (1) in data A3 from the IP address of USB network card 1 to the IP address of cellular network card 2, and convert the source IP address in TCP header (1) to the IP address of cellular network card 2. The source port is converted from the port bound to the socket2a connection in the 4G mobile phone to the port bound to the socket2b connection in the 5G mobile phone case. Exemplarily, the port bound to the socket2b connection in the 5G mobile phone case may be an unoccupied port in the 5G mobile phone case. Furthermore, the source address in the IP header (1) of the obtained data A4 is A.B.C.D, and the source port in the TCP header (1) is PROT0.

Exemplarily, after performing NAT translation, the network proxy service may record the network translation relationship, such as: w.x.y.z/PROT1—A.B.C.D/PROT0.

Exemplarily, after the network proxy server obtains the data A4, it can send the data A4 to the cellular network card 2, and the cellular network card 2 encapsulates the data A4, and then transmits the encapsulated data A4 to Modem2, and the encapsulated data A4 is transmitted to Modem2 by the Modem2. After corresponding processing is performed by A4, it is sent to the service server. Furthermore, the business server can receive the SYN packet sent by APP2, and realize the first handshake between APP2 and the business server.

Fig. 6b is a schematic diagram of data transmission exemplarily shown.

Exemplarily, after receiving the SYN packet of APP2, the service server may return an ACK (ACKnowledge, confirmation) packet to APP2. Exemplarily, Modem2 of the 5G mobile phone case can receive the ACK packet returned by the service server, and then transmit the ACK packet to the cellular network card 2, and the cellular network card 2 can obtain data B1 after corresponding processing on the data sent by Modem2, as shown in Figure 6b shows. Referring to FIG. 6b, for example, the source data in the data B1 is an ACK packet. Wherein, the IP header (1) in the data B1 includes the source IP address and the destination IP address, the destination IP address is the IP address of the cellular network card 2 such as A.B.C.D, and the source IP address is the IP address of the service server such as E.F.G.H. The TCP header (1) may include a source port and a destination port. The destination port is the port bound to the socket2b connection in the 5G mobile phone case, such as PROT0, and the source port is the port bound to the socket2 connection in the business server, such as PROT16.

Exemplarily, the cellular network card 2 can send the data B1 to the network proxy service. Then the network proxy service performs NAT conversion on data B1 according to the recorded network conversion relationship, such as: w.x.y.z/PROT1—A.B.C.D/PROT0, to obtain data B2. Exemplarily, the network proxy service performs NAT conversion on the data B1, essentially converting the destination address of the IP header (1) in the data B1 from A.B.C.D to w.x.y.z, and converting the destination port in the TCP header (1) from PROT0 to PROT1.

Exemplarily, the network proxy service may send the data B2 to the USB network card 2 . After the USB network card 2 receives the data B2, it can encapsulate the corresponding TCP header (2) and IP header (2) on the data B2 according to the TCP/IP protocol between the USB network card 1 and the USB network card 2 to obtain the data B3.

Exemplarily, the TCP header (2) may also include a source port and a destination port, the destination port is the port used for communicating with the USB network card 2 in the USB network card 1, and the source port is used for communicating with the USB network card 1 in the USB network card 2 port. The IP header (2) also includes a source IP address and a destination IP address, the destination IP address is the IP address of the USB network card 1, and the source IP address is the IP address of the USB network card 2.

Exemplarily, after the USB network card 2 encapsulates and obtains the data B3, the data may be sent to the USB network card 1 based on the connection between the USB network card 1 and the USB network card 2 .

Exemplarily, the USB network card 1 can receive the data B3, and then can decapsulate the data B3, remove the IP header (2) and the TCP header (2) of the data B3, and obtain the data B4. Among them, data B4 is substantially data B2.

Exemplarily, USB network card 1 can send data B4 to APP2 according to the destination port of TCP (1) in data B4. Exemplarily, before the data B4 reaches APP2, the IP header (1) and the TCP header (1) are removed, so the data received by APP2 is an ACK packet, so that the second handshake can be completed.

Exemplarily, APP2 may send a SYN packet again to perform a third handshake with the service server, and reference may be made to the description of the above-mentioned first handshake process, which will not be repeated here.

Exemplarily, after APP2 and the service server perform three-way handshake, the socket2 connection can be established.

Exemplarily, APP2 can connect with the service server through socket1 and socket2, and perform data interaction in parallel.

For example, APP2 is a video application. When the user uses APP2 to watch video 1, the service server can divide video 1 into two groups of business data packets (each group can include multiple business data packets), and then connect to socket2 through socket1 respectively. Connect and send these two sets of business data to APP2. Among them, Modem1 in the 4G mobile phone can receive a set of service data packets sent by the service server, and then transmit the service data packets to APP2 through the cellular network card 1. Modem2 in the 5G mobile phone case can receive another set of service data from the service server packet, and then transmit the service data packet to APP2 through cellular network card 2→network proxy service→USB network card 2→USB network card 1. In this process, the processing of the business data packets by the network card and the network proxy service can refer to FIG. 6b and the corresponding description (wherein, the source data in FIG. 6b is the business data packets), and will not be repeated here. In this way, the downlink bandwidth can be increased and the downlink time delay can be reduced.

For example, APP2 is a live broadcast application. When users use APP2 to upload video 2, APP2 can divide video 2 into two groups of business data packets (each group can include multiple business data packets), and then connect through socket1 and socket2 respectively. , and send the two sets of business data to the business server. Among them, APP2 can send a set of service data packets to the service server through the cellular network 1→Modem1 in the 4G mobile phone. APP2 can also send another set of business data packets to the service server through USB network card 1 in the 4G mobile phone → USB network card 2 in the 5G mobile phone case → network proxy service → cellular network card 2 → Modem2. In this process, the processing of the service data packets by the network card and the network proxy service can refer to FIG. 6a and the corresponding description (wherein, the source data in FIG. 6a is the service data packets), and will not be repeated here. This can increase the uplink bandwidth and reduce the uplink delay.

It should be noted that, for example, in FIG. 6a , the USB network card 1 may not encapsulate the data A1 after receiving the data A1, and directly send the data A1 to the USB network card 2, and then the USB network card 2 sends the data A1 to the network proxy service , the network proxy service performs NAT conversion on data A1. Exemplarily, in FIG. 6 b , the USB network card 2 may not encapsulate the data B2 after receiving the data B2, and directly send the data B2 to the USB network card 1, and then the USB network card 1 sends the data B2 to the APP2. That is to say, the embodiment of the present application does not limit whether the USB network card encapsulates and decapsulates the received data.

It should be noted that a possible scenario can be that the 4G mobile phone uses a Wi-Fi network, and the 5G mobile phone case uses a cellular network. Cellular network for data interaction with service servers. At this time, the socket1 established between APP2 and the business server may be a data channel between APP2—Wi-Fi network card 1—Wi-Fi hardware module 1—business server.

Another possible scenario can be that the 4G mobile phone uses a Wi-Fi network, and the 5G mobile phone case uses a Wi-Fi network, then the 4G mobile phone can cooperate with the Wi-Fi network connected to itself and the Wi-Fi network connected to the 5G mobile phone case. -Fi network for data interaction with business servers. At this time, the socket1 connection established between APP2 and the business server may be a data channel between APP2—Wi-Fi network card 1—Wi-Fi hardware module 1—business server. The socket2 connection established between APP2 and the business server may be a data channel between APP2—USB network card 1—USB network card 2—network proxy service—Wi-Fi network card 2—Wi-Fi hardware module 2—business server.

Exemplarily, the user clicks the WLAN management option 405 in Figure 4a(2), and the 4G mobile phone displays the WLAN management interface of the mobile phone case in response to the user's operation behavior; then the user operates in the WLAN management interface of the mobile phone case to control the 5G mobile phone case Connect to a Wi-Fi network. At this time, there is no need to activate the SIM2 card in the 5G mobile phone case.

Another possible scenario may be that 4G uses a cellular network, while the 5G mobile phone case uses a Wi-Fi network, then the 4G mobile phone can cooperate with its own cellular network and the Wi-Fi network connected to the 5G mobile phone case to communicate with the 5G mobile phone case. The business server performs data interaction. At this time, the socket1 connection established between APP2 and the service server may be a data channel between APP2-cellular network card 1-Modem1-service server. The socket2 connection established between APP2 and the service server may be a data channel between APP2—USB network card 1—USB network card 2—network agent service—Wi-Fi network card 2—Wi-Fi hardware module 2—business server. At this time, there is no need to activate the SIM2 card in the 5G mobile phone case.

Exemplary, when the 4G mobile phone can only use the Wi-Fi network (such as when the 4G mobile phone does not have a SIM card, or the SIM card has no call charges, or the SIM card is not in the service area, etc.), and the 5G mobile phone case uses the cellular network scenario Next, when it is necessary to use the application program of the signature type in the 4G mobile phone (such as the financial APP (such as the banking business application)), because the authentication type APP needs to send the source IP address and the authentication data together when sending the signature data to the business server. In addition to authenticating the signing data in the data packet, the business server also needs to sign the source IP address in the data packet to determine whether the source IP address in the data packet is the IP address of the cellular network. If it is determined that the source IP address in the data packet is not the IP address of the cellular network, the authentication of the source IP address will not pass, and at this time, the user cannot use the authentication-type application program. And when the 4G mobile phone uses the Wi-Fi network, when the authentication data sent by the 4G mobile phone through the socket1 connection, the IP address of the Wi-Fi network card is used as the source IP address and packaged together with the signing data. And when the authentication data sent by the 4G mobile phone through the socket2 connection, the IP address of the Wi-Fi network card, the Bluetooth network card, the P2P network card or the USB network card is used as the source address, and the authentication data is packaged together. The IP address of the Wi-Fi network card, the Bluetooth network card, the P2P network card, or the USB network card is not the address of the cellular network, so the service server will not pass the signature on the source IP address. Based on this, in the embodiment of the present application, after the cellular network card 2 of the 5G mobile phone case is established, a virtual cellular network card corresponding to the cellular network card 2 in the 5G mobile phone case is constructed in the 4G mobile phone. Subsequently, during the use of the signing APP, a TCP/IP connection with the business server can be established through the virtual cellular network card, and then the IP address of the virtual cellular network card can be used as the source IP address, and the signing data can be packaged together, through The TCP/IP connection is sent to the service server. In this way, the service server can identify that the source IP address in the data packet is the address of the cellular network, thereby passing the authentication on the source IP address.

Fig. 9a is a schematic diagram of an exemplary communication connection.

Referring to Figure 9a, for example, after the SIM2 in the 5G mobile phone case is activated, the 5G mobile phone case can create a cellular network card 2 compatible with Modem2 in the 5G mobile phone, and the 5G mobile phone case can send a prompt message to the 4G mobile phone. The information is used to prompt that the SIM2 in the 5G mobile phone case has been activated. The 4G mobile phone can respond to the prompt information, construct a virtual cellular network card in the 4G mobile phone, and virtualize an IP address for the virtual cellular network card 2 according to the IP address of the cellular network card 2 . Exemplarily, in the process of authenticating the source IP address, the service server only verifies the first three segments of the source IP address, and then can offset the last segment of the IP address of the cellular network card 2 to obtain the virtual The address of the cellular network card. For example, the IP address of the cellular network card 2 is 100.100.100.5, and the address of the virtual cellular network card may be 100.100.100.8. It should be noted that since the 5G mobile phone case is connected to the Internet through the cellular network, the data from the terminal to the server is still transmitted through the cellular data path, which will not cause data security problems.

Fig. 9b is a schematic diagram of an exemplary communication connection.

Referring to FIG. 9b(1), for example, APP2 can establish a socket1 connection with the service server through the Wi-Fi network card 1 and the Wi-Fi hardware module 1 in the 4G mobile phone. Referring to Fig. 9b(2), exemplary, the socket1 connection is the data path between APP2—Wi-Fi network card 1—Wi-Fi hardware module 1—the business server. It can be seen that the socket1 connection is essentially between APP2 and the business server A TCP/IP connection.

Exemplarily, the source IP address of the socket1 connection is the IP address of the Wi-Fi network card 1, and the destination IP address is the IP address of the service server. For example, if the IP address of Wi-Fi network card 1 is r.s.t.u, and the IP address of the service server is E.F.G.H, then the source IP address of the socket1 connection is r.s.t.u, and the destination IP address is E.F.G.H.

Referring to Figure 9b(1), for example, APP2 can use the virtual cellular network card in the 4G mobile phone, the USB network card 1, the USB network card 2 in the 5G mobile phone case, the network proxy service in the 5G mobile phone case, the cellular network card in the 5G mobile phone case Network card 2 and Modem 2 in the 5G mobile phone case establish a socket 2 connection with the business server. Referring to FIG. 9b(3), for example, the socket2 connection may include a socket2a connection and a socket2b connection. Among them, the socket2a connection is created by APP2, which is a data path between APP2—virtual cellular network card—USB network card 1—USB network card 2—network proxy service. The socket2b connection is created based on the socket2a connection trigger, and is the data path between the network proxy service-cellular network card 2-Modem2-business server. It can be seen that the socket2a connection and socket2b connection form another TCP/IP connection between APP2 and the business server.

Exemplarily, the source IP address of the socket2a connection is the IP address of the virtual cellular network card, and the destination IP address is the IP address of the service server. For example, if the IP address of the virtual cellular network card is A.B.C.E, and the IP address of the service server is E.F.G.H, then the source IP address of the socket2a connection is A.B.C.E, and the destination IP address is E.F.G.H.

Exemplarily, the source IP address of the socket2b connection is the IP address of the cellular network card 2, and the destination IP address is the IP address of the service server. For example, the IP address of the cellular network card 2 is A.B.C.D, and the IP address of the service server is E.F.G.H, then the source IP address of the socket2b connection is A.B.C.D, and the destination IP address is E.F.G.H.

Fig. 9c is a schematic diagram of data transmission exemplarily shown.

Exemplarily, APP2 first sends a SYN (synchronize, synchronization) packet to the service server, and performs a first handshake with the service server. Referring to FIG. 9c, for example, the source data sent by APP2 is a SYN packet. Exemplarily, after APP2 sends a SYN packet, the SYN packet is added with a TCP header and an IP header, and is transmitted to the virtual cellular network card. Wherein, for the convenience of subsequent description, the SYN packet with the IP header and the TCP header added can be called data A1, and the IP header added to the SYN packet can be called IP header (1), and the added TCP header will be called “A1” for SYN. is the TCP header (1).

Exemplarily, the TCP header (1) may include a source port and a destination port, the source port is the port bound to the socket2a connection in the 4G mobile phone, such as PROT1, and the destination port is the port bound to the socket2 connection in the service server, such as PROT16. The IP header (1) includes a source IP address and a destination IP address, the source IP address is the IP address of the virtual cellular network card such as A.B.C.E, and the destination IP address is the IP address of the service server such as E.F.G.H.

Exemplarily, the virtual cellular network card may directly forward the data A1 to the USB network card 1 without processing the data A1.

Continuing to refer to FIG. 9c, after the USB network card 1 receives the data A1, it can encapsulate the corresponding TCP header (2) and IP header (2) for the data A1 according to the TCP/IP protocol between the USB network card 1 and the USB network card 2, Get data A2.

Exemplarily, the USB network card 2 can send the data A3 to the network proxy service. After the network proxy service receives the data A3, it can perform NAT conversion on the data A3 to obtain the data A4. Among them, performing NAT conversion on data A3 is to convert the source IP address in the IP header (1) in data A3 from the IP address of the virtual cellular network card to the IP address of cellular network card 2, and convert the source IP address in the TCP header (1) to the IP address of the cellular network card 2. The source port is converted from the port bound to socket2a connection in the 4G mobile phone to the port bound to socket2b in the 5G mobile phone case. Exemplarily, the port bound to the socket2b connection in the 5G mobile phone case may be an unoccupied port in the 5G mobile phone case. Furthermore, the source address in the IP header (1) of the obtained data A4 is A.B.C.D, and the source port in the TCP header (1) is PROT0.

Exemplarily, after performing NAT translation, the network proxy service may record the network translation relationship, such as: A.B.C.E/PROT1—A.B.C.D/PROT0.

Fig. 9d is a schematic diagram of data transmission exemplarily shown.

Exemplarily, after receiving the SYN packet of APP2, the service server may return an ACK (ACKnowledge, confirmation) packet to APP2. Exemplarily, Modem2 of the 5G mobile phone case can receive the ACK packet returned by the service server, and then transmit the ACK packet to the cellular network card 2, and the cellular network card 2 can obtain data B1 after corresponding processing on the data sent by Modem2, as shown in Figure 9b shows. Referring to FIG. 9b, for example, the source data in the data B1 is an ACK packet. Wherein, the IP header (1) in the data B1 includes the source IP address and the destination IP address, the destination IP address is the IP address of the cellular network card 2 such as A.B.C.D, and the source IP address is the IP address of the service server such as E.F.G.H. The TCP header (1) may include a source port and a destination port. The destination port is the port bound to the socket2b connection in the 5G mobile phone case, such as PROT0, and the source port is the port bound to the socket2 connection in the business server, such as PROT16.

Exemplarily, the cellular network card 2 can send the data B1 to the network proxy service. Then the network proxy service performs NAT conversion on data B1 according to the recorded network conversion relationship, such as: A.B.C.E/PROT1—A.B.C.D/PROT0, to obtain data B2. Exemplarily, the network proxy service performs NAT conversion on the data B1, essentially converting the destination address of the IP header (1) in the data B1 from A.B.C.D to A.B.C.E, and converting the destination port in the TCP header (1) from PROT0 to PROT1.

Exemplarily, the USB network card 1 can send the data B4 to the virtual cellular network card according to the destination port of TCP(1) in the data B4.

Exemplarily, after receiving the data B4, the virtual cellular network card may forward the data B4 to APP2 without processing the data B4. Exemplarily, before the data B4 reaches APP2, the IP header (1) and the TCP header (1) are removed, so the data received by APP2 is an ACK packet, so that the second handshake can be completed.

For example, APP2 is a financial application, and the socket2 connection established by APP2 is a data channel between APP2—virtual cellular network card—USB network card 1—USB network card 2—network proxy service—cellular network card 2—Modem2—business server. After the user opens the financial application and enters the account number and password, APP2 can use the account number and password entered by the user as authentication data, and then package the authentication data and the IP address of the virtual cellular network card, and pass the virtual cellular network card in the 4G mobile phone → USB network card 1 →USB network card 2→network proxy service→cellular network card 2→Modem2, send to the service server. After the service server receives the data packet, it can identify that the source IP address in the data packet is the address of the cellular network. At this time, the service server passes the signing of the source address of the data packet, and then can authenticate the authentication data .

It should be understood that, if the 4G mobile phone uses the cellular network, a virtual cellular network card can also be established in the 4G mobile phone when the cellular network card 2 is established in the 5G mobile phone case, which is not limited in this embodiment of the present application.

It should be noted that the actual throughput rate of the socket2 connection can be monitored in real time while the 4G mobile phone uses the socket1 connection and the socket2 connection at the same time to perform data interaction with the business server in parallel. When it is detected that the actual throughput rate of the socket2 connection is less than the preset throughput threshold, the socket2 connection can be closed, and only the socket1 connection is used for data interaction with business data to reduce power consumption. Wherein, the preset throughput threshold may be set according to requirements, which is not limited in this embodiment of the present application.
