Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Method embodiment

The invention discloses a network coexistence control method based on an Android system, which comprises the following steps:

configuring network priorities, wherein the network priorities comprise a first priority, a second priority and a third priority, the first two priorities support generation of a default gateway, and the third priority only supports an intranet access function; the 3 priorities correspond to the 3 fixed scores, the higher the score is, the higher the priority is, the highest score is the first priority, the highest score is used as an external network access interface, and similarly, the lowest priority is the third priority, and only the access to the internal network is supported. In the AgentInfo of each network, the getScore () is returned to the corresponding score, so that the score of each network can be configured.

Accessing more than two networks on the equipment, including connecting one network and disconnecting one network;

and starting a network coexistence function, refreshing the network by the system according to the priority sequence configured by the routing table, storing the configuration state in the local file system, and automatically finishing the adjustment of the network priority sequence again after starting the system next time. In a specific application example, a function of network coexistence is started, the system readjusts a routing table of the system according to a configured priority order to generate a default gateway route of a first priority, only host routes are generated according to a second priority and a third priority, the routing table of each network is completed in a ConnectivityService update route method, and the corresponding routing table can be adjusted according to different network types in the method. And the configuration state is stored in a flash memory, the sequence is automatically read after the computer is started next time, and the adjustment of the network priority sequence is completed again.

In a specific application example, the embodiment of the present invention has the following basic conventions: (1) not allowing the third priority network to generate a default gateway (or default route); (2) when there are the first two priority networks present, there is and only one default gateway allowed.

In a specific application example, connecting a network specifically includes: firstly, judging whether the network is in a first priority or a second priority, if not, generating a default route, if the accessed network is in the first priority, judging whether the network of the second priority already exists in the system at the moment, if so, deleting the network default route of the second priority first, and finally generating all route information of the first priority; if the second priority does not exist, directly generating all routing information of the first priority; if the accessed network is the second priority network, whether the network with the first priority already exists in the system is judged, if so, the second priority network at the moment is not allowed to generate default routing information, and only the local routing is allowed to be generated. The specific operation can be as follows: and judging which network device the currently operated network routing table belongs to according to the netId in the updateRoutes, if the currently operated network routing table belongs to the first-priority network device, generating a default gateway, and if the currently operated network routing table does not belong to the first-priority network device, not generating the default gateway.

In a specific application example, disconnecting a network specifically includes: firstly, judging whether the network is the third priority, if so, clearing the routing information of the third priority network; if the first priority network is not the second priority network, if the first priority network is the first priority network, the first priority network is disconnected, whether the second priority network in the system exists at the moment needs to be judged, and if the second priority network exists, the default gateway of the second priority network is added after all the routing information of the first priority network is cleared. The specific operation can be as follows: when a network interface sends state change, the system calls a rematch network and requests method, when a first priority network is disconnected and a second priority network is accessed, the system needs a default gateway route at the moment, and a default gateway route is added to the second priority network in the rematch network and requests method.

The interface for adjusting the network priority is provided by the embodiment of the invention, and the network sequence of WIFI, Ethernet and 4G can be configured at will. After the opened interface is called, the changeNetworkpriority method is called, the network priority order is readjusted, and the system can refresh the network immediately to enable the three networks to meet the configuration. Meanwhile, the configuration can be saved in a local file system, and the network reconfiguration can be realized after the system is restarted.
