FIG. 3 is a block diagram of a device according to a third embodiment of the present invention. Referring to FIG. 3, the electronic device 30 includes a processor (not shown), a memory unit (not shown), an output input unit (not shown), and a connection processing system 300. The connection processing system 300 includes an operating system 301 and a wireless local area network module 302. The operating system 301 is operated by the processor and the memory unit of the electronic device 30. The method of operation is well known to those skilled in the art and will not be described herein. The wireless local area network module 302 is connected to the operating system 301. The wireless local area network module 302 further includes an antenna module 303.

In addition to using the antenna module 303 to transmit and receive data data transmitted via the wireless area network, the wireless area network module 302 further utilizes the antenna module 303 to detect surrounding Internet access points, such as the access point 310. The access point 310 is connected to one of the external servers 31 in the external network 31, and transmits and transmits data data transmitted via the wireless local area network to the external network. The external server 320 may be a web server, a mail server, or the like constructed on a Hyper-Text Transfer Protocol (HTTP), but the present invention is not limited to the above.

FIG. 4 is a flow chart showing the steps of a method for processing a network connection according to a third embodiment of the present invention. Referring to FIG. 3 and FIG. 4 simultaneously, in step S100, the operating system 301 stores the connection information of the currently connected access point and the access point currently connected in the network before entering the sleep mode. Road favorite list. It should be noted that the general operating system (such as the operating system 301 in this embodiment) stores the connection information of the connected and connected access points in a wireless network configuration table in the operating system ( In the Wireless Network Profile, the wireless local area network module (such as the wireless local area network module 302 in this embodiment) records the connection information of the connected and connected access points in a network. The network preference list (Network Preferred List) has different operating modes according to different electronic devices (for example, the electronic device 30 in this embodiment), for example, selecting one of the reading or synchronizing the wireless network configuration table and the network at any time. Preference list, etc.

The network preference list of the connection processing system 300 of the present invention may be independently built or co-built or synchronized with the wireless network configuration table of the operating system 301 and/or the network preference list of the wireless local area network module 302. Only the object of the invention can be achieved. For example, in the present embodiment, the network preference list of the connection processing system 300 is co-located with the network preference list of the wireless local area network module 302, and the wireless network configuration table of the operating system 301 records the operating system. In the non-sleep mode, the connection information of the access point and the access point in the connection is connected, and the network preference list of the connection processing system 300 is updated and stored in the wireless local area network before the operating system 301 enters the sleep mode. The network preference list/network preference list of the module 302, but the invention is not limited to this embodiment.

Referring to FIG. 3 and FIG. 4, in step S1010, the operating system 301 enters the sleep mode. In the case where the electronic device 30 is set to "Always on, and always connected", that is, on the premise of the present case, step S1011 will be executed. In step S1011, the wireless local area network module 302 detects whether there is a connectable access point (such as the access point 310) around the environment. If the wireless local area network module 302 does not detect any access point, it will continue to detect. If the wireless local area network module 302 detects an access point 310, the determination of step 102 will continue.

In step S102, the wireless local area network module 302 determines whether the connection information of the access point 310 exists in the network preference list in the connection processing system 300 to perform the processing operation of step S103. In step S103, when the network preference list has the connection information of the access point 310, the wireless local area network module 302 starts to connect to the access point 310 according to the connection information in the network preference list. Line (step S1030).

In step S1031, the wireless local area network module 302 determines whether the connection information can be used, and the network address allocated by the access point 310 is connected to the external network 31 through the access point 310. Line, for example, using the PING command. If the wireless local area network module 302 can be successfully connected to the external network 31 under such a setting, it means that the connection related setting is the same as before the operating system 301 enters the sleep mode. Therefore, the wireless local area network module 302 does not need to be The operating system 301 is woken up. At the same time, the wireless local area network module 302 establishes a connection to the external network 31 through the access point 310 and continues to maintain the connected state (step 1032).

If the wireless local area network module 302 cannot successfully connect to the external network 31 using the existing connection information setting, the wireless local area network module 302 connects to the access point 310 or the dynamic host connected to the access point 310. A Dynamic Host Configuration Protocol Server (DHCP server) (not shown) requires a new network address to be obtained (step S1033).

The wireless area network module 302 performs a test of whether or not it can connect to the external network 31 through the access point 310 after acquiring a new network address (step S1034). If the wireless local area network module 302 can be connected to the external network 31, the wireless local area network module 302 wakes up the operating system 301 after establishing the connection, and informs the operating system 301 that a new connection has been established. Take over the subsequent settings or data transmission and reception. If the wireless local area network module 302 can be connected to the external network 31, it means that the access point has the ability to connect with the external network 31, but may need to be verified, such as typing a user name and password. Connect to the external network 31. The wireless local area network module 302 then provides the relevant authentication information to the wake-up operating system 301. After the electronic device 30 passes the verification, the wireless local area network module 302 connects to the external network 31 through the access point 310 (steps). S1036).

Then, the process returns to the step S102. When the connection information of the access point 310 is not stored in the network preference list, the wireless area network module 302 first tests whether the access point 310 has the external network 31 connection. Ability (step S1037). If the tested wireless local area network module 302 can be connected to the external network 31 through the access point 310, the wireless local area network module 302 stores the connection information of the access point 310 in the connection processing system 300. In the network preference list, the wake-up operating system 301 notifies that a new connection has been established (step S1038). It is to be noted that, in the determination of step S1037, the directly connectable access point 310 is typically a wireless local area network that does not have password protection (e.g., the aforementioned WEP cryptographic protocol). Because of the network security concerns, the user can selectively perform step S1038, that is, adjust to the wireless local area network module 302 even if it has the connection capability to the external network 31. However, the present invention is not limited to the above embodiments.

If the tested wireless local area network module 302 cannot connect to the external network 31 through the access point 310, the wireless local area network module 302 similarly stores the connection information of the access point 310 in the connection processing. The system 300 has a network preference list, but the difference is that it will be marked as a disconnected item at this time to avoid the access point 310 being awakened while the operating system 301 is in the sleep mode, but lacking the connection capability ( Step S1039).

In addition, an access point (e.g., access point 310) that is determined to be inaccessible to the external network 31 may also be a wireless local area network access point that has not been previously logged in, but requires a verification procedure. Therefore, in this embodiment, the unconnected item recorded in the network preference list is only when the operating system 301 is in the sleep mode, and the connection point is not detected after the access point is detected. When the operating system 301 is not in the sleep mode, the wireless local area network module 302 will also detect the information backhaul operating system 301 of the access point 310. If the wireless local area network provided by the access point 310 requires authentication, the program needs to be authenticated. The operating system 310 provides relevant verification information for verification.

Further, if the operating system 301 and the access point 310 are successfully verified, and the wireless local area network module 302 is successfully connected to the external network 31 through the access point 310, the operating system 301 will access the access point 310. The connection information is stored in the wireless network configuration table of the operating system 301. Before the operating system 301 enters the sleep mode, the connection information of the access point 310 is updated from the wireless network configuration table to the network preference list in the connection processing system 300.

In summary, the present invention provides a method for processing a network connection and an electronic device thereof, wherein when the electronic device is in "always on, ready to connect", the operating system in which the operation is run is not searched in the sleep mode. The wireless local area network access point that does not have the external connection capability is awakened from the sleep mode, causing unnecessary power consumption and thus affecting the overall standby time.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims.
