Referring to fig. 4b, an exemplary cellular network card 2 may be created in the 5G handset housing after the SIM2 card in the 5G handset housing is activated.

For example, after the SIM2 card in the 5G mobile phone shell 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 shell to perform data interaction with the corresponding service server in parallel. The application program supporting the multi-stream concurrence may be an application program that can establish a plurality of TCP/IP (Transmission Control Protocol/Internet Protocol ) connections in parallel, such as a video application, a game application, a live broadcast application, and the like. In the embodiment of the present Application, an APP (Application) 2 in a 4G mobile phone is taken as an example of a multi-stream concurrent Application.

Fig. 5a is a schematic diagram of an exemplary connection.

Referring to fig. 5a, for example, when APP2 needs to perform data interaction with the service server, multiple TCP/IP connections may be established with the service server first, and then APP2 performs data interaction with the service server based on the established multiple TCP/IP connections. For example, the number of TCP/IP connections established by the APP2 and the service server is not limited in the embodiment of the present application, and the embodiment of the present application takes establishing two TCP/IP connections as an example for illustration.

Illustratively, the process of APP2 establishing a TCP/IP connection with the service server is essentially a process of APP2 establishing a socket connection with the service server.

Fig. 5b is a schematic diagram of an exemplary communication connection.

Referring to fig. 5b (1), APP2 may establish a socket1 connection with the service server through the cellular network card 1 and the Modem1 in the 4G mobile phone, for example. Referring to fig. 5b (2), the socket1 connection is exemplarily a data path between APP 2-the cellular network card 1-the Modem 1-the service server, and it can be seen that the socket1 connection is substantially a TCP/IP connection between APP2 and the service server.

Illustratively, 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, if 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, 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 fig. 5b (1), for example, APP2 may establish a socket2 connection with the service server through USB network card 1 in the 4G mobile phone, USB network card 2 in the 5G mobile phone, network proxy service in the 5G mobile phone, cellular network card 2 in the 5G mobile phone, and Modem2 in the 5G mobile phone. Referring to fig. 5b (3), exemplarily, the socket2 connection may include a socket2a connection and a socket2b connection. The socket2a connection is established by APP2, and is a data path between APP2, USB network card 1, USB network card 2 and network proxy service. socket2b connection is created based on socket2a connection trigger, and is a data path between a network proxy service-cellular network card 2-Modem 2-service server. As can be seen, socket2a connection and socket2b connection form another TCP/IP connection between APP2 and the service server.

Illustratively, 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, if the IP address of the USB network card 1 is w.x.y.z and the IP address of the service server is e.f.g.h, the source IP address connected to the socket2a is w.x.y.z and the destination IP address is e.f.g.h.

Illustratively, 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, if 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, the source IP address of the socket2b is a.b.c.d, and the destination IP address is e.f.g.h.

For example, APP2 may establish a socket connection with the service server by performing a three-way handshake with the service server. The process of establishing the socket1 connection with the service server by the APP2 may specifically refer to the specification in the existing protocol, and is not described herein again. The following is an exemplary description of the process of APP2 establishing a socket2 connection with a service server.

Fig. 6a is a schematic diagram of an exemplary data transmission.

Illustratively, APP2 first sends a SYN (synchronization) packet to the traffic server, and performs a first handshake with the traffic server. Referring to fig. 6a, exemplary source data sent by APP2 is a SYN packet. Illustratively, after APP2 sends out the SYN packet, the SYN packet is added with a TCP header and an IP header and is transmitted into the USB network card 1. For convenience of description, the SYN packet to which the IP header and the TCP header are added may be referred to as data A1, the IP header added to the SYN packet may be referred to as IP header (1), and the TCP header added to the SYN packet may be referred to as TCP header (1).

Illustratively, the TCP header (1) may include a source port and a destination port, where the source port is a port bound to the socket2a in a 4G mobile phone, such as PROT1, and the destination port is a port bound to the socket2 in the service server, such as PROT16. The IP header (1) comprises a source IP address and a destination IP address, wherein 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.

Illustratively, the 4G mobile phone and the 5G mobile phone communicate with each other through a USB data line using a TCP/IP Protocol or a UDP/IP (User Datagram Protocol/internet Protocol) Protocol. That is, the USB connection may be a TCP/IP connection or a UDP/IP connection, which is not limited in this embodiment. In the embodiment of the application, the USB connection between the 4G mobile phone and the 5G mobile phone shell is exemplified as a TCP/IP connection.

With continued reference to fig. 6a, after the USB network card 1 receives the data A1, the data A2 may be obtained by encapsulating 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.

For example, the TCP header (2) may also include a source port and a destination port, where the source port is a port of the USB network card 1 for communicating with the USB network card 2, and the destination port is a port of the USB network card 2 for communicating with the USB network card 1. The IP header (2) also comprises a source IP address and a destination IP address, wherein 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.

For example, after the data A2 is obtained by encapsulating the USB network card 1, 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.

For example, the USB network card 2 may receive the data A2, and then may decapsulate the data A2, and remove the IP header (2) and the TCP header (2) of the data A2 to obtain the data A3. The data A3 is substantially the data A1.

For example, the USB network card 2 may send the data A3 to the network proxy service. After receiving the data A3, the network proxy service may perform NAT conversion on the data A3 to obtain data A4. The data A3 is subjected to NAT conversion, namely a source IP address in an IP head (1) in the data A3 is converted into an IP address of a cellular network card 2 from an IP address of a USB network card 1, and a source port in the TCP head (1) is converted into a port which is connected and bound with a socket2a in a 4G mobile phone shell and is connected and bound with a socket2b in a 5G mobile phone shell. For example, the port bound for the socket2b connection in the 5G handset housing may be an unoccupied port in the 5G handset housing. Further, 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.

For example, after performing NAT translation, the network proxy service may record a network translation relationship, such as: w.x.y.z/PROT 1-A.B.C.D/PROT 0.

For example, after obtaining the data A4, the network proxy server may send the data A4 to the cellular network card 2, package the data A4 by the cellular network card 2, transmit the packaged data A4 into the Modem2, perform corresponding processing on the packaged data A4 by the Modem2, and send the processed data to the service server. And then the service server can receive the SYN packet sent by the APP2, and the first handshake between the APP2 and the service server is realized.

Fig. 6b is a schematic diagram of an exemplary data transmission.

For example, after receiving the SYN packet of APP2, the traffic server may return an ACK (acknowledgement) packet to APP2. For example, the Modem2 of the 5G mobile phone shell may receive an ACK packet returned by the service server, and then may transmit the ACK packet to the cellular network card 2, and after the cellular network card 2 performs corresponding processing on the data sent by the Modem2, data B1 may be obtained, as shown in fig. 6B. Referring to fig. 6B, the source data in the data B1 is an ACK packet, for example. The IP header (1) in the data B1 includes a source IP address and a destination IP address, the destination IP address is an IP address of the cellular network card 2, such as a.b.c.d, and the source IP address is an 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, where the destination port is a port, such as PROT0, in the 5G mobile phone shell that is connected and bound to the socket2b, and the source port is a port, such as PROT16, in the service server that is connected and bound to the socket 2.

Illustratively, the cellular network card 2 may send the data B1 to the network proxy service. The network proxy service then translates the relationship according to the recorded network, such as: w.x.y.z/PROT 1-A.B.C.D/PROT 0, and carrying out NAT conversion on the data B1 to obtain data B2. Illustratively, the network proxy service performs NAT translation on the data B1, which is substantially to translate the destination address of the IP header (1) in the data B1 from a.b.c.d to w.x.y.z, and to translate the destination port in the TCP header (1) from PROT0 to PROT1.

Illustratively, the network proxy service may send data B2 to the USB network card 2. After the USB network card 2 receives the data B2, the data B2 may be encapsulated with a corresponding TCP header (2) and an IP header (2) according to a TCP/IP protocol between the USB network card 1 and the USB network card 2, so as to obtain data B3.

Illustratively, the TCP header (2) may also include a source port and a destination port, where the destination port is a port of the USB network card 1 for communicating with the USB network card 2, and the source port is a port of the USB network card 2 for communicating with the USB network card 1. The IP header (2) also comprises a source IP address and a destination IP address, wherein 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.

For example, after the data B3 is obtained by encapsulating the USB network card 2, 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.

For example, the USB network card 1 may receive the data B3, and then may decapsulate the data B3, and remove the IP header (2) and the TCP header (2) of the data B3 to obtain the data B4. The data B4 is substantially the data B2.

For example, the USB network card 1 may send the data B4 to the APP2 according to the destination port of the TCP (1) in the data B4. Illustratively, the data B4 is removed from the IP header (1) and the TCP header (1) before reaching APP2, so that the data received by APP2 is an ACK packet, and thus, the second handshake may be completed.

For example, APP2 may send the SYN packet again to perform a third handshake with the service server, and reference may be made to the description of the process of the first handshake, which is not described herein again.

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

Illustratively, the APP2 and the service server can be connected through socket1 and socket2 for data interaction in parallel.

For example, APP2 is a video application, and when a user watches video 1 using APP2, the service server may divide video 1 into 2 sets of service data packets (each set may include a plurality of service data packets), and then send the 2 sets of service data to APP2 through socket1 connection and socket2 connection, respectively. The Modem1 in the 4G mobile phone may receive a group of service data packets sent by the service server, and then transmit the service data packets to the APP2 through the cellular network card 1. The Modem2 in the 5G mobile phone shell can receive another group of service data packets of the service server, and then transmit the service data packets to the APP2 through the cellular network card 2 → the network proxy service → the USB network card 2 → the USB network card 1. In this process, reference may be made to fig. 6b and corresponding description for processing the service data packet by the network card and the network proxy service (where the source data in fig. 6b is the service data packet), and details are not described herein again. Therefore, the downlink bandwidth can be increased, and the downlink time delay can be reduced.

For example, APP2 is a live broadcast application, and when a user uploads video 2 using APP2, APP2 may divide video 2 into 2 sets of service data packets (each set may include a plurality of service data packets), and then send the 2 sets of service data to a service server through socket1 connection and socket2 connection, respectively. The APP2 may send a set of service data packets to the service server through the cellular network 1 → Modem1 in the 4G mobile phone. The APP2 can also send another group of service data packets to the service server through the USB network card 1 in the 4G mobile phone → the USB network card 2 in the 5G mobile phone shell → the network agent service → the cellular network card 2 → the Modem 2. In this process, reference may be made to fig. 6a and corresponding description for processing the service data packet by the network card and the network proxy service (where the source data in fig. 6a is the service data packet), and details are not described herein again. Therefore, the uplink bandwidth can be increased, and the uplink time delay can be reduced.

It should be noted that, for example, in fig. 6a, after receiving the data A1, the USB network card 1 may also not encapsulate 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, and the network proxy service performs NAT conversion on the data A1. For example, in fig. 6B, after receiving the data B2, the USB network card 2 may also not encapsulate the data B2, 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.

Fig. 7a is an exemplary illustration of a connection.

Exemplarily, after the 4G mobile phone is connected with the 5G mobile phone shell through the USB, the 4G mobile phone can also establish Wi-Fi connection with the 5G mobile phone shell, and then the 4G mobile phone can establish socket2 connection with the service server through the Wi-Fi connection with the 5G mobile phone shell.

Illustratively, the user clicks on the mobile network management option 406,4g handset in fig. 4a (2) to expose the handset housing mobile network management interface in response to the user's operational behavior. Then, the user can operate in a mobile network management interface of the mobile phone shell, open the hot spot of the 5G mobile phone shell, and set the name and the password of the hot spot of the 5G mobile phone shell, and at the moment, the 5G mobile phone shell can be used as an AP (Wireless Access Point).

For example, the user may enter a WLAN management interface of the mobile phone from a setup application of the 4G mobile phone, and then connect to the hot spot of the 5G mobile phone shell by operating in the WLAN management interface of the mobile phone, for example, selecting a wireless network with the hot spot name of the 5G mobile phone shell, and inputting a corresponding password. Thus, the 4G mobile phone can be accessed to the 5G mobile phone shell as an STA (Station).

Fig. 7b is a schematic diagram of an exemplary communication connection.

Referring to fig. 7b, for example, after the 4G mobile phone establishes the Wi-Fi connection with the 5G mobile phone shell, the Wi-Fi network card 1 in the 4G mobile phone and the Wi-Fi network card 2 in the 5G mobile phone shell may establish the Wi-Fi connection.

For example, the SIM2 card in the 5G mobile phone shell may be activated as described above, and details are not described here.

Fig. 7c is a schematic diagram of an exemplary communication connection.

For example, the description of fig. 5b above may be referred to for fig. 7c, and details are not repeated here.

It should be noted that fig. 7c is different from fig. 5b in that, in fig. 7c, the 4G mobile phone and the 5G mobile phone shell perform data interaction through a Wi-Fi connection between the Wi-Fi network card 1 and the Wi-Fi network card 2. That is to say, in fig. 7c, socket1 connection is a data path between APP2 and cellular network card 1 and Modem1 and a service server, socket2 connection may include socket2a connection and socket2b connection, socket2a connection is a data path between APP2 and Wi-Fi network card 1 and Wi-Fi network card 2 and a network proxy service, and socket2b connection is a data path between network proxy service and cellular network card 2 and Modem2 and a service server.

In one possible approach, the Wi-Fi connection between the Wi-Fi network card 1 and the Wi-Fi network card 2 can be a layer 3 (network layer) connection. And then after the Wi-Fi network card 1 and the Wi-Fi network card 2 receive the data, the data need to be packaged according to the corresponding communication protocol, and then the packaged data are forwarded. For example, the communication protocol between the Wi-Fi network card 1 and the Wi-Fi network card 2 can be TCP/IP protocol.

Fig. 7d is a schematic diagram illustrating data transmission.

For example, the description of fig. 6a above may be referred to for fig. 7d, and details are not repeated here.

It should be noted that, the difference between fig. 7d and fig. 6a is that the source IP address in the IP header (1) of the data A1 in fig. 7c is the IP address of the Wi-Fi network card 1, such as r.s.t.u. The source IP address in the IP header (2) is the IP address of the Wi-Fi network card 1, and the destination IP address is the IP address of the Wi-Fi network card 2. The source port in the TCP head (2) is a port in the Wi-Fi network card 1 for communicating with the Wi-Fi network card 2, and the destination port is a port in the Wi-Fi network card 2 for communicating with the Wi-Fi network card 1.

Fig. 7e is a schematic diagram illustrating data transmission.

For example, the description of fig. 6b above may be referred to for fig. 7e, and details are not repeated here.

It should be noted that fig. 7e is different from fig. 6B in that the destination IP address in the IP header (1) of the data B2 in fig. 7c is an IP address of the Wi-Fi network card 1, such as r.s.t.u. The destination IP address in the IP header (2) is the IP address of the Wi-Fi network card 1, and the source IP address is the IP address of the Wi-Fi network card 2. The destination port in the TCP head (2) is a port in the Wi-Fi network card 1 for communicating with the Wi-Fi network card 2, and the source port is a port in the Wi-Fi network card 2 for communicating with the Wi-Fi network card 1.

In one possible approach, the Wi-Fi connection between Wi-Fi network card 1 and Wi-Fi network card 2 can be a layer 2 (data link layer) connection. And then the Wi-Fi network card 1 and the Wi-Fi network card 2 directly forward the data after receiving the data.

Fig. 8a is a schematic diagram illustrating data transmission.

For example, the description of fig. 6a above may be referred to for fig. 8a, and details are not repeated here.

It should be noted that the difference between fig. 8a and fig. 6a is that after the Wi-Fi network card 1 receives the data A1, the data A1 may be directly forwarded to the Wi-Fi network card 2 without processing the data A1, that is, the data received by the Wi-Fi network card 2 is also the data A1. And then the Wi-Fi network card 2 does not need to de-encapsulate the data A1, but directly sends the data A1 to the network proxy service.

Fig. 8b is a schematic diagram illustrating data transmission.

For example, the description of fig. 6b above may be referred to for fig. 8b, and details are not repeated here.

It should be noted that the difference between fig. 8B and fig. 6B is that after the Wi-Fi network card 2 receives the data B2, the data B2 may be directly forwarded to the Wi-Fi network card 1 without processing the data B2, that is, the data received by the Wi-Fi network card 1 is also the data B2. And then Wi-Fi network card 1 also need not to decapsulate data B2, but directly sends data B2 to APP2.

It should be understood that a Wi-Fi P2P (Peer to Peer) connection may also be established between the 4G handset and the 5G handset housing. Illustratively, the user may enter the sharing interface of the mobile phone shell by clicking the huazi sharing option in fig. 4 (2); and clicking an application icon of the sharing application on the 4G mobile phone main interface to enter a mobile phone sharing interface. And then, the user can operate in the mobile phone sharing interface and the mobile phone sharing interface to establish Wi-Fi P2P connection between the 4G mobile phone and the 5G mobile phone. At this time, socket2 connection may include socket2a connection and socket2b connection, socket2a connection is a data path between APP 2-P2P network card 1-P2P network card 2-network proxy service, and socket2b connection is a data path between network proxy service-cellular network card 2-Modem 2-service server. A process of establishing TCP/IP connection between APP2 and the service server, a process of performing service data interaction between APP2 and the service server, and a data processing manner by the P2P network card 1 and the P2P network card 1 may refer to fig. 7d and fig. 7e, or refer to fig. 8a and fig. 8b.

It should be understood that a 4G handset may also establish a bluetooth connection with a 5G handset housing. Illustratively, the user may enter the bluetooth management interface of the handset housing by clicking on the bluetooth management option in fig. 4 (2); and entering a mobile phone Bluetooth management interface from a setting application program of the 4G mobile phone. Then, the user can operate in the Bluetooth management interface of the mobile phone shell and the Bluetooth management interface of the mobile phone, and Bluetooth connection between the 4G mobile phone and the 5G mobile phone shell is established. At this time, the socket2 connection may include socket2a connection and socket2b connection, the socket2a connection is a data path between APP 2-bluetooth network card 1-bluetooth network card 2-network proxy service, and the socket2b connection is a data path between network proxy service-cellular network card 2-Modem 2-service server. The process of establishing TCP/IP connection between APP2 and the service server, the process of performing service data interaction between APP2 and the service server, and the data processing mode by the bluetooth network card 1 and the bluetooth network card 2 may refer to fig. 7d and fig. 7e, or refer to fig. 8a and fig. 8b.

It should be noted that a possible scenario may be that the 4G mobile phone uses a Wi-Fi network, the 5G mobile phone shell uses a cellular network, and at this time, the 4G mobile phone may perform data interaction with the service server in cooperation with the Wi-Fi network connected to the 4G mobile phone and the cellular network of the 5G mobile phone shell. At this time, the socket1 established by the APP2 and the service server may be a data channel between the APP 2-Wi-Fi network card 1-Wi-Fi hardware module 1-service server.

Another possible scenario may be that a Wi-Fi network is used by the 4G mobile phone, a Wi-Fi network is used by the 5G mobile phone, and then the 4G mobile phone may perform data interaction with the service server in cooperation with the Wi-Fi network connected to itself and the Wi-Fi network connected to the 5G mobile phone. At this time, the socket1 connection established between the APP2 and the service server may be a data channel between the APP 2-Wi-Fi network card 1-Wi-Fi hardware module 1-the service server. The socket2 connection established between the APP2 and the service server may be a data channel between the APP 2-USB network card 1-USB network card 2-network proxy service-Wi-Fi network card 2-Wi-Fi hardware module 2-service server.

Illustratively, the user clicks on the WLAN management option 405 in fig. 4a (2), and the 4g handset presents the WLAN management interface of the handset shell in response to the user's operation behavior; the user then operates within the WLAN management interface of the handset housing to control the 5G handset housing to connect to the Wi-Fi network. At this point, it may not be necessary to activate the SIM2 card in the 5G handset housing.

Yet another possible scenario may be that the 4G handset uses a cellular network and the 5G handset uses a Wi-Fi network, and then the 4G handset may cooperate with its own cellular network and the connected Wi-Fi network of the 5G handset to perform data interaction with the service server. At this time, the socket1 connection established between APP2 and the service server may be a data channel between APP2, the cellular network card 1, the Modem1, and the service server. The socket2 connection established between the APP2 and the service server can be a data channel between the APP 2-USB network card 1-USB network card 2-network agent service-Wi-Fi network card 2-Wi-Fi hardware module 2-service server. At this point, it may not be necessary to activate the SIM2 card in the 5G handset housing.

For example, in a scenario where the 4G handset can only use the Wi-Fi network (e.g. the 4G handset does not have the SIM card, or the SIM card does not have a charge, or the SIM card is not in the service area, etc.), and the 5G handset shell uses the cellular network, when an application program of the authorization class in the 4G handset (e.g. a financial APP (e.g. a banking application)) needs to be used, since the authentication class APP is sending authorization data, the source IP address needs to be packaged with the authentication data and sent to the service server. The service server needs to authenticate the signing data in the data packet, and also needs to sign the source IP address in the data packet, and determine whether the source IP address in the data packet is the IP address of the cellular network. If the source IP address in the data packet is determined not to be the IP address of the cellular network, the source IP address cannot be authenticated, and at this time, the user cannot use the authentication-type application program. And when the 4G mobile phone uses the Wi-Fi network, the 4G mobile phone packs the IP address of the Wi-Fi network card as the source IP address together with the signing data when the 4G mobile phone connects the authentication data sent through the socket 1. And when the 4G mobile phone is connected with the authentication data sent by the socket2, the IP address of the Wi-Fi network card or the Bluetooth network card or the P2P network card or the USB network card is used as a source address and is packaged together with the authentication data. And the IP address of the Wi-Fi network card or the Bluetooth network card or the P2P network card or the USB network card is not the address of the cellular network, so the service server can not pass the right of signing on the source IP address. Based on this, in the embodiment of the application, after the cellular network card 2 of the 5G mobile phone shell is established, a virtual cellular network card corresponding to the cellular network card 2 of the 5G mobile phone shell is established in the 4G mobile phone. Subsequently, in the using process of the signing APP, a TCP/IP connection with the service server can be established through the virtual cellular network card, then the IP address of the virtual cellular network card can be used as a source IP address, the source IP address and the signing data are packaged together, and the signing data are sent to the service server through the TCP/IP connection. 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 of the source IP address.

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

Referring to fig. 9a, for example, after the SIM2 in the 5G mobile phone shell is activated, the 5G mobile phone shell may create a cellular network card 2 adapted to the Modem2 in the 5G mobile phone, and the 5G mobile phone shell may send a prompt message to the 4G mobile phone, where the prompt message is used to prompt that the SIM2 in the 5G mobile phone shell is activated. The 4G handset may construct a virtual cellular network card in the 4G handset in response to the prompt message, and virtualize an IP address for the virtual cellular network card 2 according to the IP address of the cellular network 2. Illustratively, in the process of authenticating the source IP address, the service server only verifies the first three segments of addresses of the source IP address, and then may obtain the address of the virtual cellular network card by offsetting the last segment of the IP address of the cellular network card 2. 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, because the 5G mobile phone shell is networked through the cellular network, data is still transmitted from the terminal to the server through the cellular data path, which does not cause the data security problem.

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

Referring to fig. 9b (1), APP2 may establish a socket1 connection with the service server through a Wi-Fi network card 1 and a Wi-Fi hardware module 1 in the 4G mobile phone, for example. Referring to fig. 9b (2), exemplarily, the socket1 connection is a data path between APP 2-Wi-Fi network card 1-Wi-Fi hardware module 1-service server, and it can be seen that the socket1 connection is substantially a TCP/IP connection between APP2 and the service server.

Illustratively, 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 the Wi-Fi network card 1 is r.s.t.u and the IP address of the service server is e.f.g.h, 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 fig. 9b (1), for example, APP2 may establish a socket2 connection with the service server through a virtual cellular network card in the 4G mobile phone, a USB network card 1, a USB network card 2 in the 5G mobile phone shell, a network proxy service in the 5G mobile phone shell, a cellular network card 2 in the 5G mobile phone shell, and a Modem2 in the 5G mobile phone shell. Referring to fig. 9b (3), for example, the socket2 connection may include a socket2a connection and a socket2b connection. The socket2a connection is established by APP2 and is a data path between APP2, a virtual cellular network card, a USB network card 1, a USB network card 2 and a network agent service. socket2b connection is created based on socket2a connection trigger, and is a data path between a network proxy service-cellular network card 2-Modem 2-service server. Therefore, socket2a connection and socket2b connection form another TCP/IP connection between APP2 and the service server.

Illustratively, 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, the source IP address of the socket2a connection is a.b.c.e and the destination IP address is e.f.g.h.

Illustratively, 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, if 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, the source IP address a.b.c.d and the destination IP address of the socket2b are e.f.g.h.

For example, APP2 may establish a socket connection with the service server by performing a three-way handshake with the service server. The process of establishing the socket1 connection with the service server by the APP2 may specifically refer to the specification in the existing protocol, and is not described herein again. The following is an exemplary description of the process of APP2 establishing a socket2 connection with the service server.

Fig. 9c is a schematic diagram of exemplary data transmission.

Illustratively, APP2 first sends a SYN (synchronization) packet to the traffic server, and performs a first handshake with the traffic server. Referring to fig. 9c, the source data sent by APP2 is illustratively a SYN packet. Illustratively, after APP2 sends out the SYN packet, the SYN packet is added with a TCP header and an IP header and is transmitted into the virtual cellular network card. For convenience of description, the SYN packet to which the IP header and the TCP header are added may be referred to as data A1, the IP header added to the SYN packet may be referred to as an IP header (1), and the TCP header added to the SYN packet may be referred to as a TCP header (1).

Illustratively, the TCP header (1) may include a source port and a destination port, where the source port is a port bound to socket2a in a 4G mobile phone, such as PROT1, and the destination port is a port bound to socket2 in a service server, such as PROT16. The IP header (1) includes a source IP address and a destination IP address, the source IP address being an IP address of the virtual cellular network card, such as a.b.c.e, and the destination IP address being an IP address of the service server, such as e.f.g.h.

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

Illustratively, the 4G mobile phone and the 5G mobile phone shell communicate with each other through a USB data line by using a TCP/IP Protocol or a UDP/IP (User Datagram Protocol/internet Protocol) Protocol. That is, the USB connection may be a TCP/IP connection or a UDP/IP connection, which is not limited in this embodiment. In the embodiment of the application, the USB connection between the 4G mobile phone and the 5G mobile phone shell is exemplified as a TCP/IP connection.

With continued reference to fig. 9c, after the USB network card 1 receives the data A1, the data A2 may be obtained by encapsulating 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.

For example, after the USB network card 1 packages 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.

For example, the USB network card 2 may send the data A3 to the network proxy service. After receiving the data A3, the network proxy service may perform NAT conversion on the data A3 to obtain data A4. The data A3 is subjected to NAT conversion, namely the source IP address in the IP head (1) in the data A3 is converted into the IP address of the honeycomb network card 2 from the IP address of the virtual honeycomb network card, and the source port in the TCP head (1) is converted into the port bound with the socket2b in the 5G mobile phone shell from the port bound with the socket2a in the 4G mobile phone. For example, the port bound for the socket2b connection in the 5G handset housing may be an unoccupied port in the 5G handset housing. Further, 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.

For example, after performing NAT translation, the network proxy service may record a network translation relationship, such as: A.B.C.E/PROT 1-A.B.C.D/PROT 0.

Fig. 9d is a schematic diagram illustrating exemplary data transmission.

For example, after receiving the SYN packet of APP2, the traffic server may return an ACK (acknowledgement) packet to APP2. For example, the Modem2 of the 5G mobile phone shell may receive an ACK packet returned by the service server, and then may transmit the ACK packet to the cellular network card 2, and after the cellular network card 2 performs corresponding processing on the data sent by the Modem2, data B1 may be obtained, as shown in fig. 9B. Referring to fig. 9B, the source data in the data B1 is an ACK packet, for example. Wherein, the IP header (1) in the data B1 includes a source IP address and a destination IP address, the destination IP address is an IP address of the cellular network card 2, such as a.b.c.d, and the source IP address is an 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, where the destination port is a port bound to the socket2b in the 5G mobile phone shell, such as PROT0, and the source port is a port bound to the socket2 in the service server, such as PROT16.

Illustratively, the cellular network card 2 may send the data B1 to the network proxy service. The network proxy service then translates the relationship according to the recorded network, such as: and A.B.C.E/PROT 1-A.B.C.D/PROT 0, performing NAT conversion on the data B1 to obtain data B2. Illustratively, the network proxy service performs NAT translation on data B1, which essentially translates the destination address of the IP header (1) in data B1 from a.b.c.d to a.b.c.e, and translates the destination port in TCP header (1) from PROT0 to PROT1.

Illustratively, the network proxy service may send data B2 to the USB network card 2. After the USB network card 2 receives the data B2, the data B3 may be obtained by encapsulating the corresponding TCP header (2) and IP header (2) for the data B2 according to the TCP/IP protocol between the USB network card 1 and the USB network card 2.

For example, after the USB network card 2 packages 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.

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

For example, after receiving the data B4, the virtual cellular network card may forward the data B4 to the APP2 without processing the data B4. Illustratively, data B4 has IP header (1) and TCP header (1) removed before reaching APP2, so that the data received by APP2 is an ACK packet, and thus, the second handshake may be completed.

For example, APP2 may send the SYN packet again to perform a third handshake with the service server, which may refer to the description of the first handshake process described above and is not described herein again.

Illustratively, after three handshakes of APP2 and the service server, socket2 connection can be established.

For example, APP2 is a financial application, and the socket2 connection established by APP2 is: APP 2-virtual honeycomb network card-USB network card 1-USB network card 2-network agent service-honeycomb network card 2-Modem 2-service server. After the user opens the financial application and inputs the account and the password, the APP2 may use the account and the password input by the user as authentication data, then package the authentication data and the IP address of the virtual cellular network card, and send the authentication data and the IP address to the service server through the virtual cellular network card → USB network card 1 → USB network card 2 → network proxy service → cellular network card 2 → Modem2 in the 4G mobile phone. After receiving the data packet, the service server 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 right 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 a cellular network, the virtual cellular network card may also be established in the 4G mobile phone when the cellular network card 2 is established in the 5G mobile phone shell, which is not limited in the embodiment of the present application.

It should be noted that, in the process that the 4G mobile phone simultaneously uses socket1 connection and socket2 connection and concurrently performs data interaction with the service server, the actual throughput rate of socket2 connection can be monitored in real time. When the actual throughput rate of the socket2 connection is monitored to be smaller than the preset throughput threshold value, the socket2 connection can be closed, and data interaction is performed with service data only by using the socket1 connection, so that power consumption is reduced. The preset throughput threshold may be set as required, which is not limited in this embodiment of the present application.

For example, for a non-multi-stream concurrent application program (such as a navigation application, a browser application, a shopping application, and the like), when it is determined that the actual throughput rate of the scoket1 connection is smaller than a preset throughput threshold, or the time delay is larger than a preset time delay threshold, the socket1 connection may be closed, a socket2 connection may be established, and data interaction may be performed with the service server through the socket2 connection. For example, in the process of data interaction between the 4G mobile phone and the service server through the socket2 connection, the actual throughput rate of the socket2 connection may be monitored in real time. When the actual throughput rate of the socket2 connection is smaller than the preset throughput threshold value, the socket2 connection can be closed, the socket1 connection is established again, and data interaction is performed with service data through the socket1 connection, so that power consumption is reduced. The preset delay threshold may be set as required, which is not limited in this embodiment of the present application.

In a possible mode, when the Modem1 in the 5G handset shell and the Modem2 in the 4G handset shell are produced by the same manufacturer, after the SIM2 in the 5G handset shell is activated, the cellular network card 2 corresponding to the Modem2 can be created in the 4G handset, that is, the cellular network card is created at a far end, but the cellular network card is not created locally in the 5G handset shell.

For example, the cellular network card 2 corresponding to the Modem2 may be created at a local framework layer in a 4G mobile phone.

Fig. 10a is a schematic diagram of an exemplary communication connection.

Referring to fig. 10a, the connection established by the 5G handset housing and the 4G handset is illustratively a USB connection. After the 4G mobile phone sends the activation instruction to the 5G mobile phone shell through the USB connection, the 5G mobile phone shell can respond to the activation instruction and activate the SIM2 card, and at the moment, the 5G mobile phone shell can use the SIM2 card to connect to a network. For example, after the 5G mobile phone shell successfully activates the SIM2 card, a network card creation instruction may be generated, and the network card creation instruction is sent to the 4G mobile phone through USB connection with the 4G mobile phone. Wherein the network creation indication comprises an IP address assigned by a base station to which the 5G handset housing is connected.

For example, after receiving the network card creation instruction, the 4G mobile phone may create the cellular network card 2 in the mobile phone in response to the network card creation instruction, and set the IP address of the cellular network card 2 as the IP address allocated by the base station connected to the 5G mobile phone shell included in the network creation instruction.

Fig. 10b is an exemplary communication connection diagram.

Referring to fig. 10b (1), APP2 may establish a socket1 connection with the service server through the cellular network card 1 and the Modem1 in the 4G mobile phone, for example. Referring to fig. 10b (2), the socket1 connection is exemplarily a data path between APP 2-the cellular network card 1-the Modem 1-the service server, and it can be seen that the socket1 connection is substantially a TCP/IP connection between APP2 and the service server.

Referring to fig. 10b (1), for example, APP2 may establish a socket2 connection with the service server through the cellular network card 2 in the 4G mobile phone, the USB network card 1, the USB network card 2 in the 5G mobile phone shell, and the Modem2 in the 5G mobile phone shell. Referring to fig. 9b (3), for example, the socket2 connection may be a data path between APP2, the cellular network card 2, the USB network card 1, the USB network card 2, the Modem2, and the service server. As can be seen, socket2 connection is essentially another TCP/IP connection between APP2 and the traffic server.

Illustratively, the source IP address of the socket2 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, if 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, the source IP address of the socket2 connection is a.b.c.d and the destination IP address is e.f.g.h.

For example, referring to fig. 9c and 10b, after receiving the data A1, the cellular network card 2 may encapsulate the data A1, encapsulate the data A1 into data that can be recognized by the Modem2, such as data A1', and then send the data A1' to the USB network card 1. Then, the processing procedure of the USB network card 1 and the USB network card 2 may refer to the description of fig. 9c, which is not described herein again. For example, suppose that the USB network card 2 is decapsulated to obtain data A3', at this time, the data transport module may transport the data A3' to the Modem2, and the network proxy service is not required to perform NAT conversion on the data A3 '. Similarly, after the Modem2 receives the data, the data can be transferred to the USB network card 2 by the data transfer module without performing NAT conversion on the data source.

In a possible scenario (such as a crowd-concentrated scenario or a large traffic scenario), when the communication capability of the mobile phone a cannot meet the user requirement, the mobile phone a may establish a connection with the mobile phone B, so that the mobile phone a may perform data interaction with the service server in cooperation with the cellular capability (or wireless communication capability) of itself and the cellular capability (or wireless communication capability) of the mobile phone B, thereby increasing the bandwidth and reducing the data transmission delay.

For example, the mobile phone a and the mobile phone B are both 4G mobile phones, or the mobile phone a and the mobile phone B are both 5G mobile phones, or the mobile phone a and the mobile phone B are both 6G mobile phones, and so on. Illustratively, the mobile phone a is a 4G mobile phone and the mobile phone B is a 5G mobile phone, or the mobile phone a is a 5G mobile phone and the mobile phone B is a 6G mobile phone, and so on. It should be understood that the embodiments of the present application do not limit the wireless communication technologies used by the handsets a and B.

Illustratively, the operator of the SIM card of the mobile phone a is a first operator, and the operator of the SIM card of the mobile phone B is a second operator. The first operators may be the same or different, and this is not limited in this embodiment of the application.

Fig. 11 is an exemplary connection diagram.

Referring to fig. 11, cell phone a may establish a Wi-Fi connection with cell phone B, for example. It should be understood that, the mobile phone a and the mobile phone B may also establish one of a Wi-Fi P2P connection, a bluetooth connection, and a USB connection, and the embodiment of the present application does not limit the connection manner between the mobile phone a and the mobile phone B.

Fig. 12a is an exemplary interface diagram.

Referring to fig. 12a (1), illustratively, 1201 is a home interface for cell phone a, where the home interface 1201 for cell phone a includes one or more controls, including but not limited to: application icons (e.g., hua is an application icon of a sharing application, an application icon of a browser application, an application icon 1202 of a setting application), network identifiers, power identifiers, and the like.

Illustratively, the user clicks on the application image 1202 of the setting application, and the mobile phone a presents the setting interface in response to the operation behavior of the user, as indicated by 1203 in fig. 12a (2). For example, one or more controls may be included in the settings interface 1203, including but not limited to: account options, bluetooth options, mobile network options, desktop and wallpaper options, traffic sharing options 1204, network card management options, and application management options, among others. The user clicks on the traffic sharing option 1204, and the cell phone a presents a traffic sharing interface, as shown at 1205 in fig. 12a (3), in response to the user's operation behavior. For example, the traffic sharing interface 1205 may include one or more controls including, but not limited to: request sharing option 1206, active sharing option 1207, traffic management option 1208.

For example, when the on-off state corresponding to the active sharing option in the traffic sharing interface of the mobile phone B is the off state, if the on-off state of the sharing request option 1206 in the traffic sharing interface 1205 of the mobile phone a is the off state, the user may slide the on-off state of the sharing request option 1206 in the traffic sharing interface 1205 of the mobile phone a to request the mobile phone B to share the data path of the mobile phone B. For example, after the user slides the switch of the request sharing option 1206, the mobile phone a may send sharing request information to the mobile phone B in response to the operation behavior of the user, where the sharing request information is used to request for sharing the data path.

Illustratively, when the switch state corresponding to the active sharing option in the traffic sharing interface of the mobile phone B is the off state, if the switch state of the request sharing option 1206 in the traffic sharing interface 1205 of the mobile phone a is the on state, the mobile phone a may send the sharing request information to the mobile phone B after the mobile phone a and the mobile phone B establish the Wi-Fi connection.

For example, after receiving the sharing request information sent by the mobile phone a, the mobile phone B may display a sharing request prompt interface. Illustratively, the share request prompt interface includes one or more controls including, but not limited to: an approval option and a rejection option. For example, the sharing request prompt interface may also display sharing request information, such as "handset a requests to share the native mobile network". And the user clicks the agreement option, the mobile phone B responds to the operation behavior of the user and returns agreement sharing response information to the mobile phone A, and then the mobile phone A can share the data channel of the mobile phone B through Wi-Fi connection with the mobile phone B. And the user clicks the rejection option, the mobile phone B responds to the operation behavior of the user and returns the sharing rejection response information to the mobile phone A, and at the moment, the mobile phone A cannot share the data channel of the mobile phone B through the Wi-Fi connection with the mobile phone B.

For example, after receiving the sharing agreement response message returned by the mobile phone B, the mobile phone a may establish a socket1 connection with the service server based on the cellular network card 1 and the Modem1 of the user during the process of using the application program in the mobile phone a, and the mobile phone a may establish a socket2 connection with the service server based on the Wi-Fi network card 1, the Wi-Fi network card 2, the network proxy service, the cellular network card 2, and the Modem 2. For example, the process of establishing socket1 connection and socket2 connection between the mobile phone a and the mobile phone B may refer to the description of the process of establishing socket1 connection and socket2 connection between the 4G mobile phone and the 5G mobile phone shell, and is not described herein again.

For example, the application program in the mobile phone a is connected to the socket2 through the socket1, and the process of performing data interaction with the service server in parallel is also referred to the process of performing data interaction with the service server through the socket1 connection and the socket2 connection by referring to the application program in the 4G mobile phone, which is also not described herein again.

Illustratively, when the switch state corresponding to the active sharing option in the traffic sharing interface of the mobile phone B is the on state, after the mobile phone a and the mobile phone B establish Wi-Fi, the mobile phone B receives the sharing request information sent by the mobile phone a, and directly returns the sharing agreement response information to the mobile phone a, without displaying the sharing request prompt interface in the mobile phone B or operating in the sharing request prompt interface by the user.

In one possible approach, when the SIM card in the user's handset has abundant traffic, the user may click on the traffic management option 1208 in fig. 12a (3), and the handset displays the traffic management interface in response to the user's operation, as shown in 1209 in fig. 12a (4). Illustratively, the traffic management interface may include one or more controls including, but not limited to, traffic purchase options 1210 and traffic sale options 1211, among others. The user clicks the flow selling option 1211, and the mobile phone responds to the operation behavior of the user and displays a flow selling interface. The user can browse the selling interface, can sell the rule and the price of the flow rate, and then can operate the selling flow rate according to the requirement. For example, after the user sells the flow, the switch of the active sharing option 1207 in fig. 12a (2) may be automatically set to the on state without manual operation by the user.

In one possible approach, when the traffic of the SIM card in the user's handset is urgent, the user may click the traffic purchase option 1210, and the handset displays the traffic purchase interface in response to the user's operation behavior. The user can browse the selling interface, can purchase the rule and the price of the flow rate, and then operate and purchase the flow rate according to the requirement. Illustratively, the switch requesting the share selection 1206 of FIG. 12a (2) may be automatically set to the ON state after the user purchases the traffic, without requiring manual operation by the user.

Fig. 12b is a schematic diagram of an exemplary communication connection.

For example, the description of fig. 5b may be referred to for fig. 12b, and will not be repeated here.

It should be noted that, in fig. 12B, while APP2 in the mobile phone a still maintains the socket1 connection and the socket2 connection with the service server, when the mobile phone B uses APP2, the mobile phone B may establish the socket3 connection with the service server based on the network proxy service, the cellular network card 2, and the Modem2 in the mobile phone B. For example, as shown in fig. 12B (4), the socket3 connection may refer to a data path between APP 2-network proxy service-cellular network card 2-Modem 2-service server in the mobile phone B.

Illustratively, the source IP address of the socket3 connection is the IP address of the cellular network card 2, i.e., a.b.c.d. The destination address of the socket3 connection is the address of the service server. If APP2 in mobile phone a and APP2 in mobile phone B are the same APP, the service server connected to socket3 and the service server connected to socket2 may be the same server, and at this time, the destination address connected to socket3 may be e.f.g.h.

Illustratively, when the APP2 in the mobile phone B sends data to the service server through the socket3 connection, the network proxy server recognizes that the data is data of the application layer in the mobile phone B, may not perform NAT conversion on the data, and directly sends the data to the cellular network card 2, and then sends the data to the service server through the Modem 2.

For example, the cellular network card 2 may receive data a of APP2 in the mobile phone a returned by the service server and data B of APP2 in the mobile phone B returned by the service server.

For example, data a is shown in table 1:

TABLE 1

For example, data B is shown in table 2:

TABLE 2

Illustratively, the source IP address and the destination IP address in data a are the same as those in data B, but the port bound to socket3 in mobile phone B is different from the port bound to socket 2B; therefore, the network proxy service can perform NAT conversion according to the pre-recorded network conversion relationship and the destination IP address and the destination port of the received data, thereby determining whether to send the data received by the cellular network card 2 to the USB network card 1 or to the APP2 in the mobile phone B.

Illustratively, since the network transformation relationship of the network proxy service record is: w.x.y.z/PROT 1-a.b.c.d/PROT 0, so the network proxy service can convert data a to data C, as shown in table 3:

TABLE 3

The network proxy service may then send data C into USB network card 1, and may then transmit data C to APP2 in handset a, with reference to fig. 6 b. Since the data B does not have a corresponding network conversion relationship, the network proxy service may send the data B to the APP2 in the handset B.

Fig. 13 is an exemplary connection diagram.

Illustratively, cell phone a may establish a Wi-Fi connection with cell phone B and a bluetooth connection with cell phone C. Thus, the mobile phone a can cooperate with the cellular capability (or wireless communication capability) of itself, the cellular capability (or wireless communication capability) of the mobile phone B, and the cellular capability (or wireless communication capability) of the mobile phone C to perform data interaction with the server, thereby increasing the bandwidth and reducing the data transmission delay.

For example, the application program of the mobile phone a may establish a socket1 connection with the service server based on the own cellular network card 1 and Modem1, the application program of the mobile phone a may establish a socket2 connection with the service server based on the Wi-Fi network card 1 in the mobile phone a, the Wi-Fi network card 2 in the mobile phone B, the network proxy service in the mobile phone B, the cellular network card 2 in the mobile phone B, and the Modem2 in the mobile phone B, and the application program of the mobile phone a may establish a socket3 connection with the service server based on the bluetooth network card 1 in the mobile phone a, the bluetooth network card 2 in the mobile phone C, the network proxy service in the mobile phone C, the cellular network card 2 in the mobile phone C, and the Modem2 in the mobile phone C. Reference may be made to the description above, which is not repeated here.

It should be appreciated that handset a may establish a Wi-Fi connection with handset B and a Wi-Fi connection with handset C. Cell phone a can also establish a bluetooth connection with cell phone B and a bluetooth connection with cell phone C. The mobile phone A can also be connected with a USB and establish a Wi-Fi connection with the mobile phone C. The mobile phone A can establish Wi-Fi connection with the mobile phone B, establish USB connection with the mobile phone C, and the like; that is, the embodiment of the present application does not limit the connection manner between the mobile phone a and the mobile phones B and C.

It should be understood that, the embodiments of the present application do not limit the number of the mobile phones connected to the mobile phone a, that is, the embodiments of the present application do not limit how many data paths of the mobile phone a are used by the mobile phone a.

Illustratively, when the mobile phone a, the mobile phone B and the mobile phone C are connected through Wi-Fi, the mobile phone a may include at least two Wi-Fi network cards, one Wi-Fi network card being connected to the Wi-Fi network card in the mobile phone B, and the other Wi-Fi network card being connected to the Wi-Fi network card in the mobile phone C.

Illustratively, when the mobile phone a, the mobile phone B and the mobile phone C are connected through Wi-Fi, the mobile phone a may only include one Wi-Fi network card, and the Wi-Fi network card may serve as an AP, and the Wi-Fi network card in the mobile phone B and the Wi-Fi network card in the mobile phone C are both connected to the Wi-Fi network card of the mobile phone a. In addition, the mobile phone a is further provided with a shunting module, and when the Wi-Fi network card in the mobile phone a receives the service data of the application program, the shunting module can shunt the service data to the mobile phone B or the mobile phone C according to a preset shunting rule. For example, the shunting rule may be set as required, and the embodiment of the present application does not limit this.

For example, when the offloading module determines to offload the service data to the mobile phone B, an IP header (2) and a TCP header (2) may be added to the received data according to the manner shown in fig. 7d, where a destination IP address in the IP header (2) is an IP address of a Wi-Fi network card in the mobile phone B, and a destination port in the TCP header (2) is a port in the Wi-Fi network card of the mobile phone a, which communicates with the Wi-Fi network card of the mobile phone B.

Illustratively, when the offloading module determines to offload the service data to the mobile phone B, an IP header (2) and a TCP header (2) are added to the received data according to the manner shown in fig. 7d, where a destination IP address in the IP header (2) is an IP address of a Wi-Fi network card in the mobile phone C, and a destination port in the TCP header (2) is a port in the Wi-Fi network card of the mobile phone a, which communicates with the Wi-Fi network card of the mobile phone C.

Fig. 14 is an exemplary connection diagram.

Illustratively, a tablet computer (Wi-Fi ONLY (Wi-Fi network)) may establish a Wi-Fi connection with the mobile phone B, so that the tablet computer may perform data interaction with the server in cooperation with its own wireless communication capability and the cellular capability (or wireless communication capability) of the mobile phone, thereby increasing the bandwidth and reducing the data transmission delay.

For example, the authentication APP in the tablet pc may perform data interaction with the service server through Wi-Fi connection between the tablet pc and the mobile phone, using the cellular capability of the mobile phone. This can be referred to the description above and will not be described in detail here.

For example, after the mobile phone a shares the communication capability of the mobile phone B, because different communication modes have differences in bandwidth, delay, stability and cost, and different types of applications run by the user at the same time have different requirements on the communication capability, the embodiment of the present application may match corresponding network cards for different applications based on the application type, the performance of the network card and the preference of the user, so as to improve the user experience.

Illustratively, the application type may include at least one of: high throughput class, low latency class, low cost class, equalization class. It should be understood that the application types may also include other types, and the embodiments of the present application do not limit this.

Fig. 15 is an exemplary illustration of an interface.

For example, the user may click on the network card management option in fig. 12a (2), and the mobile phone displays the network card management interface in response to the operation behavior of the user, as shown in 1501 in fig. 15 (1). By way of example, network card management interface 1501 may include one or more controls including, but not limited to: a cellular network card 1 management option 1502, a cellular network card 2 management option, a virtual cellular network card 1 management option, a virtual cellular network card 2 management option, a Wi-Fi network card management option, and the like.

Illustratively, the user clicks the cellular network card 1 management option 1502, and the handset presents the management interface of the cellular network card 1 in response to the operation behavior of the user, as shown in 1503 in fig. 15 (2). Illustratively, the management interface 1503 of the cellular network card 1 may include one or more controls including, but not limited to, status options, priority options, user preference options, traffic billing options, and the like. Illustratively, the user slides the status option switch to turn on or off the cellular network card 1. For example, the user may enter the network card priority setting interface by clicking the priority, and then may set the priority of the cellular network card 1 in the network card priority setting interface. Illustratively, the user clicks on the user preference option, may enter the preference setting interface, and may then set the preference for the cellular network card 1 in the preference setting interface. For example, a user may enter the flow meter rate details interface to view the flow rate billing details by clicking on the flow rate billing option. Illustratively, the management interface 1503 of the cellular network card 1 also displays performance information of the cellular network card 1, including but not limited to: bandwidth, delay, packet loss rate, stability, etc.

For example, when a new network card that can be used for connecting to the server is added to the mobile phone, the network card performance of the network card may be detected, the network card performance information of the network card may be obtained, and a corresponding network card management option is added in fig. 15 (1).

Illustratively, the user may click on the application management option in fig. 12 (2), and the handset presents the application management interface in response to the user's operational behavior, as shown at 1504 in fig. 15 (3). Illustratively, the application management interface 1504 may include one or more controls, including but not limited to: application 1 management options 1505, application 2 management options, application 3 management options, application 4 management options, application 5 management options, and application 6 management options, among others.

Illustratively, the user clicks on the application 1 management option 1505, and the handset presents the management interface of the application 1 in response to the user's operational behavior, as shown at 1506 in fig. 15 (4). Illustratively, the management interface 1506 of the application 1 may include one or more controls including, but not limited to, a network card binding option, an application type setting option, and the like. For example, the user network card binding option may enter a network card binding option interface, and then a network card bound with the application program may be set in the network card binding option interface. Illustratively, the user clicks on the application type setting option, may enter the application type setting interface, and may then apply the application type of application program 1 in the application type setting interface.

For example, for an application program of a high throughput class on a 4G mobile phone, a user may set a virtual cellular network card created based on a cellular network card in a 5G mobile phone or a 5G mobile phone shell as a network card bound with the application program of the high throughput class.

For example, for a high-throughput application program on a 4G mobile phone, a user may set the Wi-Fi network card 1 connected to the Wi-Fi network card 2 in a 5G mobile phone or a 5G mobile phone shell as a network card bound to the high-throughput application program.

For example, a 4G mobile phone includes two SIM cards: SIMA cards and SIMB cards. When the SIMA card in the 4G mobile phone transacts the streaming-free package with specific application, the SIMA card in the 4G mobile phone can be set as the network card bound by the specific application program.

For example, for low-traffic-cost applications in a tablet computer, in the absence of WiFi, a user may set the Wi-Fi network card 1, which is connected between the tablet computer and the Wi-Fi network card 2 in the mobile phone, as a network card bound to the low-traffic-consumption applications in the tablet computer.

For example, when the application type of the application program is not set by the user, the application type of the application program may be determined by the electronic device.

For example, the electronic device may determine the application type of the application program according to type information carried by the application program. The electronic device may also determine the application type of the application according to the feedback information of the network-wide user for the application, and so on.

For example, when a new application is added to the mobile phone, the electronic device may determine the application type of the added application, and add a corresponding application management option in the application management interface of fig. 15 (3).

Fig. 16 is a schematic diagram illustrating an exemplary data processing flow.

S1601, when the socket connection is established by the application program, whether the application program has corresponding network card configuration information is judged.

For example, when the application establishes the socket connection, a network card matched with the application may be selected from a plurality of network cards connectable to the service server of the mobile phone to establish the socket connection.

For example, when the user sets a bound network card for the application program, the network card for establishing the socket connection may be preferentially allocated to the application program according to the user setting. When the user does not set a bound network card for the application program, the mobile phone may allocate a network card for establishing socket connection to the application program according to the network performance of each network card and the application type corresponding to the application program.

For example, when a user sets a bound network card for the application program, the mobile phone may store network card configuration information corresponding to the application program.

For example, the network card configuration information corresponding to the application program may be searched first. If the network card configuration information corresponding to the application program is found, indicating that the user sets a bound network card for the application program; at this time, S1602 may be performed. If the network card configuration information corresponding to the application program is not found, it indicates that the user does not have a network card which is not bound by the application program; at this time S1604 may be performed.

And S1602, determining the network card bound with the application program according to the network card configuration information.

For example, when the network card configuration information corresponding to the application program is found, the network card bound to the application program may be determined according to the network card configuration information.

S1603, socket connection is established based on the network card bound with the application program.

For example, after determining the network card set by the user and bound to the application program, the socket connection may be established for the application program based on the network card bound to the application program. Therefore, the application program can establish socket connection on the network card bound by the user and communicate with the service server, so that the requirement of the user on the corresponding communication capacity of the application program can be met, and the user experience is improved.

For example, for a high throughput application program on a 4G mobile phone, a user may set a virtual cellular network card created based on a cellular network card in a 5G mobile phone or a 5G mobile phone shell as a network card bound to the high throughput application program.

For example, a 4G mobile phone includes two SIM cards: SIMA cards and SIMB cards. When the SIMA card in the 4G mobile phone transacts the streaming-free package of the specific application, the SIMA card in the 4G mobile phone can be set as the network card bound by the specific application program.

And S1604, acquiring the application type of the application program, and acquiring network card performance information of the network cards.

Illustratively, the network card in the mobile phone may include a network card that can directly perform data interaction with the service server, for example, a cellular network card 1 in fig. 5b, and a Wi-Fi network card 1 in fig. 9 b.

For example, the network card in the mobile phone may further include a network card for performing data interaction with the service server through connection with a network card in another electronic device, such as a USB network card 1 in fig. 5b, a Wi-Fi network card 1 in fig. 7b, a virtual cellular network card in fig. 9a, and a cellular network card 2 in fig. 10 b.

For example, if the network card configuration information corresponding to the application program is not found, the application type of the application program may be obtained, and the network performance information of each network card may be obtained.

For example, when the user sets the corresponding application type for the application program, the mobile phone may store the type setting information corresponding to the application program.

When the type setting information corresponding to the application program of the user is found, the application type set for the application program by the user can be obtained from the type setting information; when the type setting information corresponding to the application program is not found, the application type determined by the system for the application program may be obtained, which is not limited in the embodiment of the present application.

And S1605, matching the network card with the optimal performance for the application program according to the network card performance information corresponding to the plurality of network cards and the application type of the application program.

Illustratively, according to the application type corresponding to the application program, the network performance information of each network card is adopted for calculation, and the score of each network card on the dimension corresponding to the application type is determined. And then matching the optimal network card for the application program according to the score of each network card on the dimension corresponding to the application type.

Illustratively, the network performance information may include at least one of: bandwidth, delay, packet loss rate, and billing unit price. It should be understood that the network card performance information may also include more or less parameters than those shown above, and the embodiment of the present application does not limit this.

For example, if the application type of the application program is a high throughput type, the score of each network card in the throughput dimension may be calculated according to the network performance information of each network card, and the following formula may be referred to:

F_IO＝a1*bandwidth+a2*rtt+a3*lossrate+a4*unitprice

wherein, F _ IO represents a score of a network in a throughput dimension, bandwidth is a bandwidth grade (the larger the bandwidth, the higher the grade), rtt is a delay grade (the smaller the delay, the higher the grade), losrate is a packet loss rate grade (the smaller the packet loss rate, the higher the grade), and unit price is a charging unit price grade (the lower the unit price, the higher the grade). a1 is a weight corresponding to a bandwidth level, a2 is a weight corresponding to a delay level, a3 is a weight corresponding to a packet loss rate level, and a4 is a weight corresponding to a charging unit price level, where a1+ a2+ a3+ a4=1, and a1, a2, a3, and a4 may all be set as required, which is not limited in this embodiment of the application. Optionally, a1 may be set relatively high to increase the weight of the network card throughput level.

For example, the network card with the largest F _ IO (i.e., the highest throughput rate) may be selected as the optimal network card matched with the application program.

For example, if the application type of the application program is a low latency type, the score of each network card in the latency dimension may be calculated according to the network performance information of each network card, which may refer to the following formula:

F_LATENCY＝b1*bandwidth+b2*rtt+b3*lossrate+b4*unitprice

wherein, F _ LATENCY represents a score of the network in the delay dimension, bandwidth is a bandwidth grade (the larger the bandwidth is, the higher the grade is), rtt is a delay grade (the smaller the delay is, the higher the grade is), lossrate is a packet loss rate grade (the smaller the packet loss rate is, the higher the grade is), and unit is a charging unit price grade (the lower the unit price is, the higher the grade is). b1 is a weight corresponding to a bandwidth level, b2 is a weight corresponding to a delay level, b3 is a weight corresponding to a packet loss rate level, and b4 is a weight corresponding to a charging unit price level, where b1+ b2+ b3+ b4=1, and b1, b2, b3, and b4 may be set as required, which is not limited in this embodiment of the present application.

Optionally, c4 may be set to be relatively high to increase the weight of the charging price level, which is not limited in this embodiment of the present application.

For example, the network card with the largest F _ COST (i.e., the lowest traffic COST) may be selected as the optimal network card matched with the application.

For example, if the application type of the application program is a balance type, the score of each network card in performance balance may be calculated according to the network performance information of each network card, and the following formula may be referred to:
