Embodiment 1

[0021] Such as figure 2 As shown, a network selection method of an Android system includes the following steps carried out in sequence:

[0022] Step 1: When there is a new network access in the Android system, judge whether the newly accessed network is available. If the newly accessed network is not available, continue to use the current network for communication. Network priority rules, compare the priority of the newly accessed network with the network with the highest priority in use. If the priority of the newly accessed network is higher than that of the in-use network, go to step 2. If the priority of the network is lower than that of the active network, continue to use the active network for communication;

[0023] Wherein, the preset network priority rule is mobile network>Ethernet>WIFI.

[0024] Step 2: Determine whether the network in use is Ethernet, if so, proceed to step 3, if not, proceed to step 4;

[0025] Step 3: continue to transmit the data packet whos...

Abstract

The invention belongs to the field of communication technology, and discloses a network selection method for an Android system, which includes the following steps in sequence: Step 1: When a new network is accessed in the Android system, according to a preset network priority rule, the Compare the priority of the newly accessed network with the network with the highest priority in use; Step 2: Determine whether the network in use is Ethernet, if so, proceed to Step 3, if not, proceed to Step 4; Step 3: Continue to transmit the data packet whose destination address is the Ethernet interface to the Ethernet interface, and transmit the data packet whose destination address is not the Ethernet interface to the interface of the newly connected network; Step 4: Eliminate the network in use, and the Android system switches to The link of the newly connected network. This method can ensure that in the scenario where the device connected to the Ethernet port of the main control device of the Android system needs to communicate, even if a network with a higher priority than the Ethernet goes online, the Ethernet port can guarantee communication.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a network selection method for an Android system. Background technique [0002] The existing main control device of the Android system can support mobile network, Ethernet, and wifi, but the network link has a priority relationship. Once the priority is set, the system network link will be subject to the setting. If the system default priority order is: mobile network>Ethernet>WIFI. Under normal circumstances, if the mobile network is online, the system will remove Ethernet and WIFI from the communication link. By default, all network requests go through the mobile network link. For some application scenarios, such as the main control device of Android, mobile data is used at this stage, but at the same time, other devices are connected to the Ethernet port, which needs to be communicated through the Ethernet port. For details, please refer to figure 1 , figure 1...
