The layered architecture divides the software into several layers, each layer having a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, the Android system may be divided into four layers, an application layer, an application framework layer, an Android runtime (Android runtime) and system library, and a kernel layer, from top to bottom, respectively.

The terminal device 100 in the embodiment of the present application may be a mobile phone, a tablet computer, a wearable device, a television, and other terminal devices that can be equipped with an android system.

In the related technology, the android system supports multiple networks such as mobile data, Wi-Fi, Bluetooth and Ethernet, the networks are prioritized, and after a high-priority network is connected, the system disconnects a low-priority network. At the same time, only one network is allowed to be online, and the online network is called the default network. For example, after the mobile data network is connected, the Wi-Fi network is connected, and the system disconnects the data network because the Wi-Fi network has high priority; if the network of the same level is connected with the network of the later connection in the time sequence, the network of the later connection is set as the default network, and the network of the earlier connection is disconnected, so that one network is always kept online.

Each network corresponds to an access device, for example, a router is used to access a Wi-Fi network, the access device of the Wi-Fi network is the router, for example, the access device corresponding to the data network is a base station, the access device of the bluetooth network is an opposite-end bluetooth device connected, and when an ethernet connection camera is used, the camera is an access device corresponding to the ethernet. After the access device accesses the terminal device, a system of the terminal device establishes a corresponding interface to facilitate communication with the corresponding access device. If the terminal device sends a data packet to a certain access device, the system of the terminal device will first obtain the interface of the access device and realize the communication between the terminal device and the access device through the network connecting the access device and the terminal device. Different types of access devices have different types of networks, and the different types of networks correspond to different types of interfaces, for example, interfaces corresponding to Wi-Fi networks are wlan0 and wlan1, and interfaces corresponding to ethernet networks are eth0 and eth 1.

Taking an example that a network connecting the access device and the terminal device is an ethernet network, when the first access device accesses the terminal device, a flow in the related art is shown in fig. 3, which includes the following contents:

after the first access device accesses, in step 301, the kernel layer establishes a network interface eth 0.

In step 302, an IP address is assigned to interface eth 0.

In step 303, the frame layer detects a new network join. After the kernel layer establishes the interface eth0, an event is reported to the frame layer (located in the application framework layer of fig. 2), and an event listener exists in the frame layer, and after the event listener hears the event uploaded by the kernel layer, the event listener indicates that the frame layer detects the network join.

In step 304, a network number is assigned to the network, such as to network 100.

In step 305, interface eth0 is added to network 100.

In step 306, the route associated with interface eth0 is added to network 100.

Finally, in step 307, the frame layer sets the network 100 as a default network.

It should be noted that the event uploaded by the kernel layer indicates the name of the interface, and the frame layer determines what kind of network is based on the character composition of the name of the interface, for example, eth starts with ethernet and wlan starts with Wi-Fi.

The routing is divided into two types, including non-gateway routing and gateway routing. The non-gateway route sends out the data packet sent to a specified IP network segment from a specified network port (interface); the gateway route is called as a default route, and is used for sending out a data packet from a certain specified network port under the condition that all non-gateway routes in a routing table cannot be matched. Whether the routing is gateway routing or non-gateway routing, the corresponding relation between the IP address and the interface identifier is stored in the routing table, and the interface identifier is used for calling a corresponding interface. For example, the IP address of the interface eth0 is 192.168.1.3, the subnet mask is 255.255.255.0, all packets accessing the 192.168.1 network segment are defined to be sent from eth0 corresponding to the non-gateway route, the gateway route will define all packets accessing the rest network segment to be sent from eth0, and eth0 is an interface identifier for invoking the corresponding interface eth 0. It can be seen that for the case of only one network, both the non-gateway route and the gateway route are assigned to the same portal. After accessing the first access device, if the second access device is accessed, the specific process is shown in fig. 4, and includes the following steps:

after the second access device accesses, in step 401, the kernel layer establishes a network interface eth 1.

In step 402, an IP address is assigned to interface eth 1.

In step 403, the frame layer detects a new network join. After the kernel layer establishes the interface eth0, an event is reported to the frame layer, and the frame layer has an event listener, and the event listener monitors the event uploaded by the kernel layer, that is, the event listener indicates that the frame layer detects network joining.

In step 404, a network number is assigned to the network, such as to network 101.

In step 405, interface eth1 is added to network 101.

In step 406, the route associated with interface eth1 is added to network 101.

Finally, in step 407, the frame layer sets network 101 as the default network and disconnects network 100.

If the terminal device supports more device accesses, the procedure is the same as that in fig. 4 described above when accessing a third, a fourth, and so on more access devices. However, the above system only allows one network to be online by default, and even if a terminal device can access multiple devices, the system cannot realize simultaneous communication of the multiple devices through the corresponding multiple networks.

As shown in fig. 5, the multi-network communication method provided in the embodiment of the present application includes the following steps:

the kernel layer accesses an access device of the first network in step 501.

The embodiment of the present application supports multiple networks such as mobile data, Wi-Fi, bluetooth, and ethernet, and the access device of the first network may be a device such as a bluetooth headset and a camera, which is not limited in the embodiment of the present application.

The kernel layer establishes a first interface for the first network and assigns a first IP address for the first interface in step 502.

In step 503, if the second network is the default network, the framework layer generates a first non-gateway route of the first network based on the first interface and the first IP address of the first network, joins the first non-gateway route and the first interface to the second network, and keeps the second network as the default network.

Compared with the prior art, after the multi-network communication method is adopted in the embodiment of the application, the first interface access flow is consistent with the flow in the prior art, and native logic is adopted, so that no change is needed. The method is different from the prior art if after accessing a first access device, the terminal device accesses another access device again.

For example, when a terminal device accesses a first access device, a network and a route condition existing in an android system at this time are as shown in fig. 6, the android system includes a network 100, which is a default network, the network 100 includes a non-gateway route of an interface eth0, an interface eth0, and a gateway route of an interface eth0, the network 100 is a network connecting the terminal device and the access device, the interface eth0 is an interface connecting the terminal device and the access device, and is also an interface of the network 100, and the non-gateway route of the interface eth0 and the gateway route of the interface eth0 are the non-gateway route and the gateway route generated based on the interface eth0 and the IP address of the network 100.

If the terminal device accesses the second access device, the flowchart is shown in fig. 7, and includes the following contents:

in step 701, the kernel layer establishes a network interface eth 1. Corresponding to step 502, a first interface is established for the first network, and the network interface eth1 is the first interface.

In step 702, an IP address is assigned to interface eth 1. A first IP address is assigned to the first interface corresponding to step 502.

In step 703, the frame layer detects a new network join. After the kernel layer establishes the interface eth1, an event is reported to the frame layer, and the frame layer has an event listener, and the event listener monitors the event uploaded by the kernel layer, that is, the event listener indicates that the frame layer detects new network joining.

In step 704, a network number is assigned to the network, such as to network 101.

If the system detects that a default network 100 already exists, which default network 100 corresponds to the second network in step 503, then in step 705, interface eth1 is added to the network 100.

In step 706, the non-gateway route of interface eth1 is added to the network 100.

Finally, in step 707, the frame layer does not set network 101 as the default network, and keeps network 100 as the default network.

It should be noted that, if the terminal device accesses multiple access devices, all gateway routes in multiple interfaces corresponding to the multiple access devices are deleted in the embodiment of the present application. During testing, when discovering that the terminal device accesses a plurality of access devices, the presence of gateway routing can cause routing confusion, which easily causes that an interface of a certain access device cannot be accessed. Therefore, in order to enable each interface to be used normally, all gateway routes are deleted, and only non-gateway routes are reserved to realize the communication capability of the local area network in the embodiment of the application.

As shown in fig. 8, after the second access device accesses, the network and routing conditions in the terminal device system include: the default network 100 includes an interface eth0 and an interface eth1, which correspond to the first access device and the second access device, respectively, and a non-gateway route of the interface eth0 and a non-gateway route of the interface eth1, and there is no interface and route in the network 101, but the network cannot be deleted because this is a network established by the framework layer corresponding to the interface eth1, and although the network 101 does not provide a routing service, some information of the interface eth1 is stored, and this information can be used in a process of setting the network 101 as a default network after the default network 100 is disconnected.

For example, if the default network 100 is disconnected, that is, the first access device is disconnected, the network 101 is set as the default network, the non-gateway routing interface eth1 of the interface eth1 is added to the network 101, and the network 100 is also deleted, where the network and routing conditions in the terminal device system are as shown in fig. 9, and include: default network 101 interface eth1, corresponding to the second access device, and interface eth1 non-gateway routing.

It should be added that if there are more devices accessing the terminal device, the flow is similar to the flow in fig. 7, and only the interface, the IP address, the network number, and the non-gateway route of the interface of the device are adjusted accordingly. Taking the third access device as an example, the flow is shown in fig. 10, and includes the following contents:

in step 1001, the kernel layer establishes a network interface eth 2. Corresponding to step 502, a first interface is established for the first network, and the network interface eth2 is the first interface.

In step 1002, an IP address is assigned to interface eth 2. A first IP address is assigned to the first interface corresponding to step 502.

In step 1003, the frame layer detects a new network join. After the kernel layer establishes the interface eth2, an event is reported to the frame layer, and the frame layer has an event monitor which monitors the event uploaded by the kernel layer, that is, the event monitor indicates that the frame layer detects a new network join.

In step 1004, the network is assigned a network number, such as network 102.

If the system detects that a default network 100 already exists, which default network 100 corresponds to the second network in step 503, then in step 1005, interface eth2 is added to the network 100.

In step 1006, the non-gateway route of interface eth2 is added to network 100.

Finally, in step 1007, the frame layer does not set network 102 as the default network, and keeps network 100 as the default network.

As shown in fig. 11, the network and routing conditions in the system of the terminal device after the third access device accesses the terminal device include: the default network 100 includes an interface eth0, an interface eth1, and an interface eth2, which correspond to the first access device, the second access device, and the third access device, and a non-gateway route of the interface eth0, a non-gateway route of the interface eth1, and a non-gateway route of the interface eth2, and there is no interface or route in the network 101 and the network 102. In the above default network 100, the three access devices can communicate simultaneously through the corresponding interfaces, and by deleting the gateway route, the situation that a certain interface cannot be accessed due to route confusion caused by the gateway route is avoided, and the communication efficiency is improved.

In some embodiments, if a default network disconnection is detected, selecting a new default network based on network priority; and adding the designated non-gateway route in the default network into the new default network based on the network number of the new default network, wherein the designated non-gateway route is the rest non-gateway route in the default network except the non-gateway route of the default network.

For example, as shown in fig. 8, there are 2 networks in the terminal device: network 100 and network 101. If the default network 100 is disconnected, the framework layer detects that the network 100 is lost, the network 101 with the highest priority is selected according to the network priority to be set as the default network, the interface eth1 is removed from the network 100 and then added into the network 101, and the non-gateway route of the interface eth1 is removed from the network 100 and then added into the network 101.

It should be noted that, if it is detected that the default network is disconnected and there are more than 2 networks in the terminal device, a new default network is selected according to the network priority. For example, priorities are fixed for various networks in the android system, Ethernet > Wi-Fi > mobile data, and a network with the highest priority is selected as a default network according to the priority when the default network is selected; if there are multiple networks with the same priority, then the first network found is taken as the default network, for example, there are multiple networks in the current system, including wlan0, eth0, eth1, eth2, etc., the system will look at each network in turn, if the priorities of eth0, eth1, eth2 are the highest and equal, because eth0 is the first network looked at, then eth0 is selected as the default network.

In other embodiments, if a disconnection of the non-default network is detected, non-gateway routes of the non-default network are deleted from the default network. For example, network 102 is a non-default network, and if a disconnection of network 102 is detected, non-gateway routes of network 102 are removed from network 100. Moreover, since the network 102 itself does not include an interface and a route, the embodiment of the present application deletes the network 102 from the system, and assuming that the network and the route in the android system after the access of the third access device are as shown in fig. 11, the network and the route in the system after the network 102 is disconnected will be as shown in fig. 8.

It is added that if all non-default network disconnections are detected, the gateway route of the default network is added to the default network. When the non-default network is completely disconnected, only the interface eth0 is left in the default network 100, and the gateway route of eth0 is added to the network 100 in the embodiment of the application, so as to meet the requirement that the device accesses the internet.

Fig. 12 is a diagram of an application scenario of a multi-network communication method in the embodiment of the present application. The drawing comprises the following steps: terminal equipment 100, interface 1, interface 2, interface 3, and camera 1, camera 2 and camera 3 connected with the interface respectively. The interface 1 is connected to the camera 1 through a network 100, the interface 2 is connected to the camera 2 through a network 101, and the interface 3 is connected to the camera 3 through a network 102.

In some embodiments, if target data is sent to access devices of multiple target networks, an interface of an access device of each target network is searched in a default network, and the target data is distributed to a corresponding access device through each target network interface. For example, as shown in fig. 12, if the terminal device is connected with 3 cameras, the access devices of the multiple target networks are 3 cameras, and the interfaces corresponding to the 3 cameras are searched in the default network, such as interface 1, interface 2, and interface 3 in fig. 12, and the target data is distributed to the corresponding cameras through each camera interface; or, if the three cameras need to send the acquired pictures to the terminal device, the pictures can be simultaneously sent to the terminal device through respective corresponding interfaces. Compared with the prior art that only one default network can be kept online, and one default network corresponds to an interface of one access device, so that communication can be performed only with one access device.

To sum up, the first non-gateway route is added to the default network and the default network is continuously used, so that the multiple access devices can simultaneously communicate through the non-gateway route included in the default network, the simultaneous communication between the terminal device and the multiple access devices is realized, the communication efficiency is improved, the problem of complex network conversion operation is avoided, and the user experience is improved.
