First, the concept to which the present invention relates will be explained.
And (4) IPV6: internet Protocol Version 6, is the next generation IP Protocol used to replace Internet Protocol Version 4 (IPV 4). Because the network address resources of the IPV4 are limited, the application and the development of the Internet are severely restricted, and therefore, the IPV6 is designed for solving the problem of the number of the network address resources.
Dual system terminal equipment: the terminal equipment with two systems, such as a dual-system mobile phone, is characterized in that the two systems run on a one-step mobile phone, and processes, networks and data of the two systems are isolated from each other and do not affect each other, so that the data security of the two systems is ensured.

When the terminal device 11 needs to access the internet, a connection is made with the server 13 through the body modem 12, and IPV6 data packets are sent to the server 13 to access the internet.
The following describes the technical solution of the present invention and how to solve the above technical problems in detail by using specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a schematic flowchart of a communication method according to an embodiment of the present invention, and as shown in fig. 2, the method may include:
s21, receiving an IPV6 data packet sent by a terminal device through a target system, wherein the terminal device is provided with two systems, the two systems comprise the target system, and the IPV6 data packet comprises an IPV6 address.
The IPV6 data packet is based on an IPV6 protocol, two systems are arranged in the terminal equipment, and processes, networks and data of the two systems are isolated from each other, so that the working independence and data safety of the two systems are guaranteed.
When two systems in the terminal equipment need to access the internet based on the IPV6 protocol to realize simultaneous internet access of the two systems, for each system, the modem first receives an IPV6 data packet sent by the terminal equipment through the target system, where the IPV6 data packet includes a corresponding IPV6 address. The modem can also obtain the corresponding IPV6 address after receiving the IPV6 data packet.
In the embodiment of the present invention, the target system is any one of two systems of the terminal device. When any one system of the terminal equipment needs to be connected with the internet for communication, the above operation is referred to, if two systems of the terminal equipment need to be connected with the internet for communication at the same time, the terminal equipment sends corresponding IPV6 data packets to the modem through the two systems respectively, and then for each IPV6 data packet, the above operation is referred to, where IPV6 addresses of IPV6 data packets of different systems are different.
And S22, sending the IPV6 data packet to a server.
And after acquiring the IPV6 data packet, the modem sends the IPV6 data packet to a server, wherein the server is a server to be accessed by a target system.
And S23, receiving a response data packet corresponding to the IPV6 data packet from the server.
After receiving the IPV6 data packet, the server responds to the IPV6 data packet to obtain a response data packet, and then sends the response data packet to the modem. The modem receives the response data packet sent by the server.
And S24, sending the response data packet to the terminal equipment according to the IPV6 address.
After receiving the response data packet, the modem sends the response data packet to the terminal equipment according to the IPV6 address, and because the IPV6 addresses corresponding to different systems are different, the terminal equipment can judge which system the response data packet corresponds to according to the IPV6 address, so that the response data packet can be sent to a corresponding target system of the terminal equipment according to the IPV6 address, and data transmission of the target system and the server is realized.
The communication method provided by the embodiment of the invention is applied to a modem, and the method firstly receives an IPV6 data packet sent by a terminal device through a target system, wherein the terminal device is provided with two systems, the target system is any one of the two systems, and the IPV6 data packet comprises an IPV6 address; then, the modem sends the received IPV6 data packet to the server, receives a response data packet corresponding to the IPV6 data packet from the server, and sends the response data packet to the terminal equipment according to the IPV6 address. The communication method provided by the embodiment of the invention is realized by a modem when a terminal device needs to access the internet, the IPv6 data packet sent to the modem comprises an IPv6 address, then the response data packet sent by a server is obtained, and then the corresponding response data packet is sent to a target system of the terminal device according to the IPv6 address, when two systems of the terminal device need to access the internet, the IPv6 data packets sent by the two systems can be processed, because the IPv6 addresses of the IPv6 data packets of different systems are different, the data of the two systems can be distinguished according to the IPv6 address, the data of the two systems are ensured to be independent and not interfered with each other, and the internet access of the dual-system terminal device based on the IPv6 protocol is realized.
The embodiment of the present invention will be described in detail below using specific examples. The two systems of the terminal equipment are respectively a first system and a second system, the IPV6 data packet sent by the terminal equipment through the first system is a first IPV6 data packet, the first IPV6 data packet comprises a first IPV6 address, the IPV6 data packet sent by the terminal equipment through the second system is a second IPV6 data packet, and the first IPV6 data packet comprises a first IPV6 address.
Fig. 3 is a signaling diagram of a communication method according to an embodiment of the present invention, as shown in fig. 3, including:
s301, the terminal device allocates a first IPV6 address to the first IPV6 data packet, and allocates a second IPV6 address to the second IPV6 data packet.
The first system and the second system are two systems of the terminal device, for example, the terminal device may include two android systems, and data of the two systems are independent.
Fig. 4 is a schematic diagram of data transmission of a terminal device according to an embodiment of the present invention, and as shown in fig. 4, two systems of the terminal device are respectively a working system and a living system, and network data of the two systems are isolated from each other, where the working system may be used as a first system and the living system as a second system, or the living system may be used as the first system and the working system as the second system. The embodiment of the invention takes a working system as a first system and a living system as a second system as an example.
S302, the terminal device sends a first IPV6 data packet to the modem through the first system, and sends a second IPV6 data packet to the modem through the second system.
When two systems access the internet through an IPV6 protocol at the same time, an IPV6 data packet of each system needs to be sent to a modem through a route, the rule of the route needs to be configured in advance at a terminal device when the terminal device dials up, and only if the relevant route rule is configured in advance, the two systems of the terminal device can surf the internet based on the IPV6 protocol. As shown in fig. 4, the working system includes APP, the living system also includes APP, when a user operates APP in the working system and APP in the living system, the terminal device needs to access the IPV6 network through the working system and the living system at the same time, and at this time, the corresponding first IPV6 data packet and second IPV6 data packet are sent to the virtual network cards corresponding to the respective systems through sockets (sockets). In fig. 4, the first IPV6 address of the first IPV6 packet is shown as rmnet10 dd00: 0. The first IPV6 address and the second IPV6 address are internal addresses of IPV6 packets, and it can be seen that the first IPV6 packet and the first IPV6 address are different from the second IPV6 address of the second IPV6 packet.
S303, the modem receives the first IPV6 data packet and the second IPV6 data packet.
The terminal equipment sends the first IPV6 data packet to a virtual network card corresponding to a first system through a socket, and sends the second IPV6 data packet to a virtual network card corresponding to a second system through the socket, and then according to a preset routing rule, the terminal equipment sends the first IPV6 data packet of the first system and the second IPV6 data packet of the second system to a corresponding real network card in the modem through a network bridge route, so that the first IPV6 data packet and the second IPV6 data packet are successfully sent to the modem, and the modem successfully receives the first IPV6 data packet and the second IPV6 data packet.
S304, the modem carries out network address conversion processing on the first IPV6 address and the second IPV6 address to obtain a corresponding first network address and a corresponding second network address.
Before the modem sends the IPV6 data packet to the server, it is also necessary to perform network address translation processing on the IPV6 address of the IPV6 data packet to obtain a corresponding network address. Network address translation is a technique of rewriting the original IPV6 address when an IPV6 packet passes through a route, and can perform broadband sharing.
The reason why the network address conversion processing is required in the embodiment of the present invention is that the address header of the IPV6 packet on the terminal device is an intranet IP, and if the IPV6 packet inside the terminal device is directly sent to the internet, the internal IP address of the terminal device cannot be routed on the internet, that is, the IPV6 address cannot be identified by the network. Therefore, if the terminal device needs to access the IPV6 network, the terminal device first performs network address conversion processing on the IPV6 address of the intranet.
Specifically, before sending data on the modem network card to the base station, according to the IPV6 network address translation rule configured by the system, the local first IPV6 address of the first IPV6 data packet of the first system is dynamically translated into the first network address allocated by the server, and the local second IPV6 address of the second IPV6 data packet of the second system is dynamically translated into the second network address allocated by the server.
For example, the data forwarding function of the IPV6 may be opened on the terminal device by executing the script, and meanwhile, when the terminal device dials up to access the internet, a network address conversion rule of the IPV6 address is configured by using a certain tool (e.g., ip6 tables), so that the local IPV6 address in the IPV6 data in the working system and the living system is dynamically converted into a network address that can be recognized by the network.
As shown in fig. 4, after the bridge routing and network address translation processing, the first IPV6 address is translated into the first network address rmnet0 XX: XX: XX: XX: XX: XX: XX/64, the second IPV6 address is translated into the first network address rmnet1 XX: XX: XX: XX: XX: XX: XX/64, and the first network address and the second network address are addresses that can be identified by a network or a server.
S305, the modem sends the first IPV6 data packet and the second IPV6 data packet to the server according to the first network address and the second network address.
After the first IPV6 address and the second IPV6 address are subjected to network address conversion processing, a first network address and a second network address which can be identified by a network or a server are obtained, then the modem sends a first IPV6 data packet to the server according to the first network address, and sends a second IPV6 data packet to the server according to the second network address, so that the IPV6 data packets of a working system and a living system are successfully sent to a network side.
S306, the server receives the first IPV6 data packet and the second IPV6 data packet.
S307, the server responds to the first IPV6 data packet to obtain a first response data packet, and responds to the second IPV6 data packet to obtain a second response data packet.
After receiving the first IPV6 data packet, the server responds according to the content of the first IPV6 data packet to obtain a first response data packet, and similarly, after receiving the second IPV6 data packet, the server responds according to the content of the second IPV6 data packet to obtain a second response data packet. The first response data packet and the second response data packet are both required to be sent to the terminal device, the first response data packet is a response obtained by operating the first system, and the second response data packet is a response obtained by operating the second system.
As shown in fig. 4, after receiving the first IPV6 data packet, the modem sends the first IPV6 data packet to the base station, and accesses the private network server through the base station, where the private network server is a server to be accessed by the first system (i.e., the operating system), and then the private network server responds to the first IPV6 data packet to obtain a first response data packet. Similarly, after receiving the second IPV6 data packet, the modem sends the second IPV6 data packet to the base station, and accesses the public network server through the base station, where the public network server is a server to be accessed by the second system (i.e., a living system), and then the public network server responds to the second IPV6 data packet to obtain a second response data packet. The data flow diagram for both systems is shown in fig. 4, where the solid lines indicate the data flow for the working system and the dashed lines indicate the data flow for the living system. It can be seen that the data flow directions of the two systems are independent from each other, and the data of the two systems are distinguished without affecting each other according to the different IPV6 addresses of the IPV6 data packets of the two systems.
S308, the server sends the first response data packet and the second response data packet to the modem.
The server obtains a first response data packet according to the content response of the first IPV6 data packet, and sends the first response data packet and a second response data packet to the modem after obtaining the second response data packet according to the content response of the second IPV6 data packet, wherein the first response data packet comprises a first network address, and the second response data packet comprises a second network address.
S309, the modem receives the first response data packet according to the first network address and receives the second response data packet according to the second network address.
After the server sends the response data packet to the modem, the modem receives the response data packet corresponding to the IPV6 data packet from the server according to the network address of the IPV6 data packet. Specifically, the modem receives a first response packet from the server according to the first network address and receives a second response packet from the server according to the second network address.
S310, the modem converts the first network address to obtain a first IPV6 address, and converts the second network address to obtain a second IPV6 address.
After receiving the response data packet, the modem performs network address conversion processing on the network address in the response data packet to obtain a corresponding IPV6 address. The network address translation process here is a reverse process to the aforementioned network address translation process, in which the IPV6 address is translated into a corresponding network address, and the network address translation process here is a process of translating a network address into a corresponding IPV6 address.
Specifically, the modem performs network address translation processing on the first network address to obtain a first IPV6 address, and performs network address translation processing on the second network address to obtain a second IPV6 address. Through the conversion, the network address of the IPV data packet is converted into the local IPV6 address in the terminal equipment, and the local IPV6 address can be identified by the terminal equipment.
And S311, sending a first response data packet to the terminal equipment according to the first IPV6 address, and sending a second response data packet to the terminal equipment according to the second IPV6 address.
After the second network address conversion processing is performed to obtain the corresponding IPV6 address, a response packet may be sent to the terminal device according to the IPV6 address. Specifically, a first response data packet and a second response data packet are sent to the terminal device, where the first response data packet includes a first IPV6 address, and the second response data packet includes a second IPV6 address.
S312, the terminal device receives the first response packet and the second response packet.
After receiving the first response data packet and the second response data packet, the terminal device can also obtain a first IPV6 address of the first response data packet and a second IPV6 address of the second response data packet. Because the first IPV6 address and the second IPV6 address are different, and the first IPV6 address is carried when the first system sends the first IPV6 data packet, and the second IPV6 address is carried when the second system sends the second IPV6 data packet, the terminal device can know that the first response data packet is a response of the first IPV6 data packet according to the first IPV6 address, and can know that the second response data packet is a response of the second IPV6 data packet according to the second IPV6 address, so that the first response data packet is distributed to the APP of the first system for processing according to the first IPV6 address and the second IPV6 address, and the second response data packet is distributed to the APP of the second system for processing.
And sending the second response data packet to the second system according to the second IPV6 address allocated to the second IPV6 data packet by the second system, thereby realizing the surfing of the second system. Because the address information of the first system and the second system is different, the two systems do not influence each other when accessing the internet, and the function that the two systems access the IPV6 network simultaneously can be realized.
The communication method provided by the embodiment of the invention is applied to a modem, and the method firstly receives an IPV6 data packet sent by a terminal device through a target system, wherein the terminal device is provided with two systems, the target system is any one of the two systems, and the IPV6 data packet comprises an IPV6 address; then, the modem sends the received IPV6 data packet to the server, receives a response data packet corresponding to the IPV6 data packet from the server, and sends the response data packet to the terminal equipment according to the IPV6 address. The communication method provided by the embodiment of the invention is realized by the modem when the terminal equipment needs to access the internet, the IPv6 data packet sent to the modem comprises an IPv6 address, then the response data packet sent by the server is obtained, and then the corresponding response data packet is sent to the target system of the terminal equipment according to the IPv6 address, when two systems of the terminal equipment need to access the internet, the IPv6 data packets sent by the two systems can be processed, because the IPv6 addresses of the IPv6 data packets of different systems are different, the data on the two systems can be distinguished according to the IPv6 address, the data of the two systems are ensured to be independent and not interfered with each other, and the internet access of the double-system terminal equipment based on the IPv6 protocol is realized.
