In the prior art, in small terminal devices such as wearable devices, after two internet surfing channels of a Modem and a bluetooth are switched, the time consumption from next data request to response is increased. This is because at the time of a network channel switch, some transmission control protocol (transmission control protocol, TCP) connections may already be established, and the state of these connections may be in an inactive state during the data transceiving and connection-maintaining phases. These connections are equivalent to having been disconnected after the network channel is switched, but because there is no transmission and reception of the data packet at present, no connection interruption is perceived, and the connection interruption is not perceived until the next time of re-transmitting and receiving data, at this time, the reconnection process is performed, which has a problem of increasing the time consumption.

The embodiment of the application provides a switching method of a surfing access, which is used for carrying out the following processing:

1) After Bluetooth connection, the Modem is powered down to perform delayed power-down processing, and switching of a network connection channel is performed in a delay process;

2) And in the process of powering on the Modem after the Bluetooth disconnection, after the Modem is powered on normally, the connection adopting the Bluetooth channel is reconnected immediately so as to reduce the time consumption from the next data request to the response.

For easy understanding, the following embodiments of the present application will take a terminal device having a structure shown in fig. 1 as an example, and specifically describe a method for switching a network access provided in the embodiments of the present application in conjunction with a drawing and an application scenario.

The method for switching the internet access provided by the embodiment of the application may include the following two processes in states:

1) Bluetooth disconnection state: in this state, the terminal device 100 uses the Modem path to access the internet. After bluetooth connection, the Modem cannot immediately power down, and needs to delay power down, and in the delay power down process, the terminal device 100 needs to switch the network path of the current connection.

2) Bluetooth connection state: in this state, the terminal device 100 uses the bluetooth to access the internet, and the Modem is in the powered-down state. When the Bluetooth is disconnected, the Modem is powered on immediately, and in the process of powering on the Modem, the terminal equipment 100 does not have a network for use, but once the Modem works normally, the terminal equipment 100 immediately switches the current existing connection, so that the time window that no network is available at present is reduced, and the probability of failure of the subsequent request is reduced.

Fig. 2 is a schematic diagram of state switching of two internet access paths of bluetooth and Modem according to an embodiment of the present application, fig. 2 shows all states of the two internet access paths in the terminal device 100, and the state switching shown in fig. 2 is triggered by different events respectively.

1) State 1- > state 2.

In this case, after the bluetooth connection, the Modem needs to be powered down to reduce power consumption, in order to avoid all failures of the currently processed request caused by sudden power down, the terminal device 100 adopts a delayed power down policy, sets a 30 second timeout timer, and switches the network access channel to the established connection in the delayed power down process, thereby ensuring that the current connection request is established from the bluetooth channel after the Modem is actually powered down. After all established connections are successfully switched, the terminal device 100 notifies the Modem to power down immediately.

2) State 2- > state 3.

If after the 30 second timer times out, there is still some connection not established, which indicates that there is a problem in the current network state or server state, the probability of this scenario itself is low, and in order to avoid the power consumption of the power-up process of the Modem, the terminal device 100 also notifies the Modem to power down immediately.

3) State 3- > State 4- > State 5

The switch from state 3 to state 4 is triggered by the bluetooth disconnection, in which state the Modem needs to be powered on immediately, and in this state, the terminal device 100 does not have the network connection capability at present, and the period of time from the Modem power-on to the normal operation will definitely fail if there is data transmission, but from the aspect of probability, the data transmission and reception will not always exist, and at this time, the method for reducing the probability of data transmission and reception errors is to shorten the time window without the network connection capability as much as possible. After the state 4 is switched to the state 5, when the Modem has the internet surfing capability, the terminal device 100 immediately switches all the connections currently established through the bluetooth channel to the Modem channel.

In the embodiment of the present application, the connection status information (ConnectionInfo) of each connection established by the terminal device 100 may include the attributes shown in table 1.

TABLE 1

For established connections, the terminal device 100 may use a linked list to manage, and facilitate traversing the state of each connection when switching network channels. FIG. 3 is a schematic diagram of a linked list according to one embodiment of the present application.

The following describes a method for switching a network access according to an embodiment of the present application with reference to a flowchart.

Fig. 4 is a flowchart of a method for switching a network access according to an embodiment of the present application, where the method for switching a network access according to the embodiment may be applied to a terminal device 100, and as described above, the terminal device 100 may include a wireless communication module 160 and a mobile communication module 150, the terminal device 100 establishes a first network channel through the mobile communication module 150, and the terminal device 100 establishes a second network channel through the wireless communication module 160; the network channel currently adopted by the terminal device 100 is a first network channel, and the second network channel is currently in a disconnected state. In this embodiment, the mobile communication module 150 may be connected to the network through a Modem, and the wireless communication module 160 may be connected to the network through bluetooth.

As shown in fig. 4, the method for switching the internet access may include:

step 401, starting a timer after detecting that the second network channel is switched from the disconnected state to the connected state.

Step 402, traversing the connection currently established by the terminal device 100 before the timing duration of the timer arrives. Step 403 or step 405 is then performed.

The timing duration of the timer may be set automatically according to system performance and/or implementation requirements during specific implementation, and in this embodiment, the length of the timing duration of the timer is not limited, for example, the timing duration of the timer may be 30 seconds.

In step 403, if there is a first unprocessed connection in the currently established connection, connection status information of the first unprocessed connection is obtained.

If it is determined that the first unprocessed connection is in the idle state according to the connection state information of the first unprocessed connection, the first unprocessed connection is rebuilt on the second network channel, and the network channel currently used by the first unprocessed connection is recorded as the second network channel.

The connection status information of the first unprocessed connection may be as shown in table 1. As can be seen from table 1, the connection status information includes currentStatus, and the terminal device 100 may determine whether the first unprocessed connection is in the idle state according to the currentStatus in the connection status information, specifically, when the value of currentStatus is "0", the terminal device 100 may determine that the first unprocessed connection is in the idle state.

In this embodiment, recording the network channel currently used by the first unprocessed connection as the second network channel may be: the value of useChannel in the connection status information of the first unprocessed connection is set to "0".

In step 405, if there is no first unprocessed connection in the currently established connection and the delay switching list stored in the terminal device 100 is empty, the mobile communication module is subjected to power-down processing.

Specifically, the powering-down processing of the mobile communication module may be: and powering down the Modem.

In addition, in this embodiment, after step 401, after the timing duration of the timer arrives, the terminal device 100 may also perform power-down processing on the mobile communication module.

In the above-mentioned switching method of the internet access, after detecting that the second network channel is switched from the disconnected state to the connected state, starting a timer, traversing the connection currently established by the terminal device 100 before the timing duration of the timer is reached, and if a first unprocessed connection exists in the currently established connection, acquiring connection state information of the first unprocessed connection. If the first untreated connection is in an idle state according to the connection state information of the first untreated connection, reestablishing the first untreated connection on the second network channel, and recording the network channel currently used by the first untreated connection as the second network channel, so that the time consumption from the next data request to the response can be reduced after the internet surfing channels of small-sized terminal equipment such as wearable equipment are switched.

Fig. 5 is a flowchart of a method for switching a network access according to another embodiment of the present application, as shown in fig. 5, in the embodiment shown in fig. 4 of the present application, after step 403, the method may further include:

in step 501, if it is determined that the first unprocessed connection is in a state of transmitting or receiving data according to the connection state information of the first unprocessed connection, the first unprocessed connection is inserted into the delay switching list stored in the terminal device 100. Step 502 is then performed.

Specifically, referring to table 1, when the value of currentStatus in the connection state information of the first unprocessed connection is "1" or "2", the terminal device 100 may determine that the first unprocessed connection is in a state of transmitting or receiving data, and thereafter, the terminal device 100 may insert the first unprocessed connection into the delay switching list held by the terminal device 100.

Step 502, a response returned by the network side is received over the first unprocessed connection.

Wherein the above-mentioned response is a response of the network side to the network request sent by the terminal device 100 through the first unprocessed connection. The network request may be, for example, a hypertext transfer protocol (hyper text transfer protocol, HTTP) network request.

Step 503, determining whether the network request is successful according to the response returned by the network side. Step 504 or step 507 is then performed.

Step 504, if the network request is successful, determining whether the first unprocessed connection is in the delay switch list.

In step 505, if the first unprocessed connection is in the delay switch list, the first unprocessed connection is rebuilt on the second network channel, and the network channel currently used by the first unprocessed connection is recorded as the second network channel.

Specifically, recording the network channel currently used by the first unprocessed connection as the second network channel may be: the value of useChannel in the connection status information of the first unprocessed connection is set to "0".

Step 506, deleting the first unprocessed connection from the delay switch list.

In step 507, if the network request is unsuccessful, it is determined whether the network channel currently adopted by the terminal device 100 has been switched to the second network channel.

In step 508, if the network channel currently adopted by the terminal device 100 has been switched to the second network channel, the first unprocessed connection is reconnected to the network side using the second network channel.

Specifically, reconnecting the first unprocessed connection with the network side using the second network channel may be: reconstructing the first unprocessed connection on the second network channel.

Step 509, after the first unprocessed connection is successfully reconnected to the network side, retransmitting the network request through the first unprocessed connection.

That is, when the network is transmitting or receiving data, connection switching cannot be performed, and judgment needs to be started again after an error occurs in response to return or timeout.

1) If the network request is successful, in addition to returning the result to the application layer, the terminal device 100 also synchronously triggers a detection to see if the current connection is in the delayed switching list, if so, the direct start switching logic switches the connection on the bluetooth path, and after the switching is completed, the current connection is removed from the delayed switching list.

2) If the network request fails, whether the current network channel is switched or not needs to be detected, the scene mainly occurs in the situation that the current connection is not switched in time when the timer is overtime, the Modem is powered down, the current request failure is probably caused by switching, the bottom layer needs to be reconnected once, and the network request is repeated once, so that the influence of the powering down of the Modem on the upper layer application is minimized.

In the embodiments shown in fig. 4 to 5, the processing flow of the terminal device 100 in the state 1- > state 2- > state 3 shown in fig. 2 is described, and in the embodiment shown in fig. 6, the processing flow of the terminal device 100 in the state 3- > state 4 shown in fig. 2 is described.

Fig. 6 is a flowchart of a method for switching a network access according to still another embodiment of the present disclosure, as shown in fig. 6, in the embodiment shown in fig. 4 of the present disclosure, after step 404, the method may further include:

in step 601, after detecting that the second network channel is switched from the connected state to the disconnected state and the mobile communication module is in the normal working state, traversing the connection currently established by the terminal device 100.

In step 602, if there is a second unprocessed connection in the currently established connection, it is determined whether the network channel used by the second unprocessed connection is the first network channel.

If the network channel used by the second unprocessed connection is not the first network channel, step 603, reestablishing the second unprocessed connection on the first network channel and recording the network channel currently used by the second unprocessed connection as the first network channel.

Specifically, recording the network channel currently used by the second unprocessed connection as the first network channel may be: the value of useChannel in the connection status information of the second unprocessed connection is set to "1".

The present embodiment describes the processing flow of the terminal device 100 from state 3 to state 4, which is required to switch from traversal to traversal because all connections need to be reconnected. Thus, all reestablishing this time window from bluetooth disconnected to all connections is the network unavailable time window, and the smaller this window, the shorter the network unavailable time, and the higher the availability of the overall system.
