In order to make the invention, the method, the objects and the advantages of the present invention more obvious, the following detailed description of the preferred embodiments and the accompanying drawings. The scope of the invention is defined by the scope of the appended claims.

1 is a block diagram of a hardware system showing a method of automatically converting an access point according to an embodiment of the present invention. As shown in FIG. 1 , the electronic device 100 includes a processing unit 102 , a storage unit 104 , a wireless module 106 , and a GPS positioning system 108 . For example, the electronic device 100 can be a notebook computer, a tablet computer, an e-book, a mobile phone, a smart phone, a PDA phone, and/or other devices that can transmit signals via a wireless network. For example, the processing unit 102 can include a single central processing unit (CPU) or a plurality of parallel processing units associated with a parallel processing environment for executing operating systems, modules, and applications. Program. The storage unit 104 includes a read only memory (ROM), a flash ROM, a random access memory (RAM), an erasable programmable read only memory, and an electronic Programmable read-only memory, scratchpad, hard disk, and/or computer readable storage medium in any other type known in the art to be used to store programs executable by processing unit 102 Module. Generally, a program module includes a routine, a program, an object, a component, or a web service to perform an instant message conversion of a peer-to-peer communication system (instant). Message switch) function. The wireless module 106 includes an 802.11 wireless network card for access point (AP) communication.

In the embodiment of the present invention, the electronic device 100 establishes a wireless connection with the first WiFi access point provided by a mobile device via the wireless module 106. In the present invention, the mobile device can be a smart phone or a tablet or the like. After the wireless module 106 establishes a wireless connection with the first WiFi access point provided by the mobile device, the processing unit 102 compares whether the first WiFi access point is in the list 110 according to a list 110 in the storage unit 104. For example, the list 110 records related information of the connected WiFi access point (ie, MAC address, geographic location information, authentication information, etc.), and each WiFi access point in the list 110 has a corresponding media storage. A control (MAC) location is taken, and each WiFi access point in the list 110 can correspond to a location (ie, a reference location) when the WiFi access point is first connected to the electronic device 100. When the first WiFi access point is not in the list 110, the representative wireless module 106 is connected to the first WiFi access point for the first time. Then, the processing unit 102 performs a first position when the positioning electronic device 100 establishes a connection with the first WiFi access point provided by the mobile device through the GPS positioning system 108. Next, the processing unit 102 stores the first WiFi access point and the first location information obtained after the location in the list 110. When the processing unit 102 establishes a wireless connection with the first WiFi access point provided by the mobile device for the first time, the first WiFi access point provided by the mobile device is classified as a fixed WiFi access point. When the electronic device 100 moves to another location, a second WiFi access point is detected and the wireless module 106 is connected to the second WiFi access point, and the second WiFi access point is not in the list 110 (representing the wireless mode) When the group 106 is connected to the second WiFi access point for the first time, the processing unit 102 also classifies the second WiFi access point as a fixed WiFi access point. Processing unit 102 transmits GPS positioning system 108 The second location when the positioning electronic device 100 establishes a connection with the second WiFi access point, the processing unit 102 stores the second WiFi access point and the second location information obtained after the location in the list 110. For example, when the processing unit 102 is not in the list 110 of the first/second WiFi access point, the wireless module 106 is considered to be connected to the first/second WiFi access for the first time. point.

2 is a flow chart showing a method of determining an access point according to an embodiment of the present invention. In step S202, when the wireless module 106 detects two or more fixed WiFi access points (ie, the first WiFi access point and the second WiFi access point provided by the mobile device) at the same location, the processing unit 102 obtains the location information of the current electronic device 100 through the GPS positioning system 108. In step S204, the location information of the corresponding detected WiFi access point stored in the storage unit 104 is read. In an embodiment of the invention, the processing unit 102 first reads the first location information corresponding to the first WiFi access point. In step S206, it is determined whether the read position and the current position (ie, the current position) of the electronic device 100 are greater than a predetermined distance according to the read position information. If it is greater than the predetermined distance, it proceeds to step S208. If it is less than the predetermined distance, it progresses to step S210. For example, the predetermined distance is 500 meters, but is not limited thereto. In other embodiments of the invention, the predetermined distance may also be less than 500 meters, such as 300 meters, and the predetermined distance may be more than 500 meters, such as 700 meters.

In step S208, the WiFi access point corresponding to the read location information is changed to a mobile WiFi access point. In this embodiment, the processing unit 102 first compares the first location according to the first location information and whether the current location of the electronic device 100 is greater than 500 meters. If the first location and the electronic device 100 The current location distance is greater than 500 meters, and the processing unit 102 changes the first WiFi access point to a mobile WiFi access point (ie, sets the first WiFi access point provided by the mobile device as a mobile WiFi access point) . After the processing unit 102 compares the first WiFi access point, it proceeds to step S210. In step S210, the processing unit 102 determines whether there is still a fixed WiFi access point. If there is a fixed WiFi access point, the process returns to step S204. If there is no fixed WiFi access point, the process proceeds to step S212 to end the flowchart. In the embodiment of the present invention, the processing unit 102 then reads the second location information corresponding to the second WiFi access point, and then compares the second location according to the second location information and whether the location of the electronic device 100 is greater than 500 meters. If the second location is less than 500 meters from the current location of the electronic device 100, the processing unit 102 still classifies the second WiFi access point as a fixed WiFi access point.

For example, after the wireless module 106 of the electronic device 100 is connected to the first WiFi access point provided by the mobile device at home, the processing unit 102 compares the first WiFi access according to a list 110 in the storage unit 104. Is the point in the list 110? When the first WiFi access point is not in the list 110, the processing unit 102 stores the first WiFi access point and the first location information when establishing the connection in the list 110 and returns the first WiFi access point. The class is a fixed access point. When the electronic device 100 moves to the company 10 kilometers away from the mobile device, the wireless module 106 detects the second WiFi access point, and the processing unit 102 compares the second WiFi according to the list 110 in the storage unit 104. Whether the point is in the list 110. When the second WiFi access point is not in the list 110, the processing unit 102 transmits the second WiFi access point and the second location information when the connection is established (ie, the processing unit 102 transmits The second location information when the global positioning system obtains connection with the second WiFi access point is stored in the list 110, and the second WiFi access point is classified as a fixed WiFi access point. Because the mobile device and the electronic device 100 are simultaneously moved to the company, the wireless module 106 can detect two fixed WiFi access points (ie, the first WiFi access point provided by the mobile device and the second WiFi storage address of the company). Take a point). Then, the processing unit 102 obtains the location information of the current electronic device 100 through the global positioning system, and the processing unit 102 compares the current location information of the electronic device 100 with the first location information of the first WiFi access point or the second WiFi access point. Two location information. At this time, after the comparison, the processing unit 102 knows that the first location of the first connection with the first WiFi access point and the current position of the electronic device 100 exceed 500 meters, and is now also capable of accessing the first WiFi. The point establishes a connection, so the processing unit 102 changes the first WiFi access point to a mobile WiFi access point. Next, the processing unit 102 compares the location information of the electronic device 100 with the second location information of the second WiFi access point. After the comparison, the processing unit 102 knows that the second location of the second WiFi access point establishment connection is less than 500 meters from the current electronic device 100, so the processing unit 102 still classifies the second WiFi access point as a fixed type. WiFi access point.

In another embodiment, FIG. 3 is a flow chart showing another method of determining an access point according to an embodiment of the present invention. In step S302, the wireless module 106 determines whether to connect to any WiFi access point. If the wireless module 106 determines that it has been connected to a WiFi access point, it proceeds to step S304. If the wireless module 106 determines that it is not connected to a WiFi access point, it returns to step S302. In step S304, the processing unit 102 compares whether the connected WiFi access point is in the list 110 of the storage unit 104, when the connected WiFi is connected. When the access point is not in the list 110, the processing unit 102 stores a reference location of the connected WiFi access point and the connected device's WiFi access point to the list 110. In step S306, after a predetermined time has elapsed, the processing unit 102 obtains the current location of the electronic device 100 through the GPS positioning system 108. In step S308, the processing unit 102 compares the reference position of the WiFi access point connected to the storage unit 104 with the current position of the electronic device 100 by more than a predetermined distance. When the reference location of the connected WiFi access point and the current location of the electronic device 100 are greater than the predetermined distance and the wireless module 106 can still establish a wireless connection with the WiFi access point, proceed to step S310. When the reference location of the connected WiFi access point and the current location of the electronic device 100 are less than the predetermined distance, or when the reference location of the connected WiFi access point and the current location of the electronic device 100 are greater than the predetermined distance and When the wireless module 106 cannot establish a wireless connection with the WiFi access point, the process proceeds to step S312. In step S310, the connected WiFi access point is set as a mobile WiFi access point. In step S312, the WiFi access point is still classified as a fixed WiFi access point. In step S314, the flowchart is ended.

In the embodiment of the present invention, the mobile WiFi access point is that the current location of the electronic device 100 can still be the same MAC when the reference address corresponding to the mobile WiFi access point in the list 110 exceeds a predetermined distance. The address is a WiFi access point, and the fixed WiFi access point is a WiFi access point that cannot be connected by the same MAC address when the electronic device 100 is more than a predetermined distance from the reference address. In the embodiment of the present invention, when the electronic device 100 wants to select a WiFi access point to establish a wireless connection, the wireless module 106 first selects a fixed WiFi access point (ie, a fixed type). The priority of the WiFi access point is higher than the priority of the mobile WiFi access point).

Figure 4 is a flow chart showing a method of automatically converting an access point in accordance with an embodiment of the present invention. The mobile WiFi access point and the fixed WiFi access point mentioned in the following steps are known from the steps mentioned in FIG. In other words, the steps shown in Fig. 2 can be performed at any time point in Fig. 3. In step S402, an electronic device has been connected to the mobile WiFi access point. In step S404, when the electronic device enters the signal range of the fixed WiFi access point, it is determined whether the electronic device is performing data transmission with the mobile WiFi access point. For example, it is determined whether the electronic device has data transmission such as video and audio downloading, sending and receiving mail, video call or upload sharing with the mobile WiFi access point. If the electronic device is currently transmitting data with the mobile WiFi access point, the process proceeds to step S406. If the electronic device does not perform data transmission with the mobile WiFi access point at this time, the process proceeds to step S408. In step S406, it is judged whether or not the data transmission is ended. If the data transfer has not ended, the process returns to step S406 to continue the determination. If the data transfer has ended, it proceeds to step S408. In step S408, the wireless connection between the electronic device and the mobile WiFi access point is interrupted, and the electronic device is automatically connected to the fixed WiFi access point.

When the wireless module 106 in the electronic device 100 is communicating with a mobile WiFi access point and the electronic device 100 enters the signal range of a fixed WiFi access point, the processing unit 102 determines whether the wireless module 106 is present. Data transfer is being performed with a mobile WiFi access point. If the wireless module 106 is currently transmitting data with the mobile WiFi access point, the processing unit 102 waits until the data transmission ends, and causes the wireless module 106 to automatically convert the wireless connection from the mobile WiFi access point to the fixed WiFi. Access point (ie no The line module 106 automatically connects the electronic device 100 to a stationary WiFi access point). If the wireless module 106 does not perform data transmission with the mobile WiFi access point, the processing unit 102 immediately causes the wireless module 106 to automatically convert the wireless connection from the mobile WiFi access point to the fixed WiFi access point. point. For example, when the wireless module 106 in the electronic device 100 is downloading video and audio data through a wireless connection with the mobile WiFi access point, if the electronic device 100 moves to a fixed WiFi access point at this time In the range, the processing unit 102 does not immediately cause the wireless module 106 to switch the electronic device from the mobile WiFi access point to the fixed WiFi access point, but waits until the audio and video data is downloaded, and then the wireless module 106 automatically Converting an electronic device from a mobile WiFi access point to a stationary WiFi access point. For example, when the wireless module 106 in the electronic device 100 is connected to the mobile WiFi access point but does not perform data transmission, if the electronic device 100 moves to the signal range of a fixed WiFi access point. The processing unit 102 directly causes the wireless module 106 to automatically convert the electronic device from the mobile WiFi access point to the fixed WiFi access point.

Figure 5 is a flow chart showing an automatic conversion access point method in accordance with an embodiment of the present invention. The mobile WiFi access point and the fixed WiFi access point mentioned in the following steps are known from the steps mentioned in FIG. In other words, the steps shown in Fig. 2 can be performed at any point in time in Fig. 5. In step S502, an electronic device has been connected to the fixed WiFi access point. In step S504, it is determined whether the electronic device is moving. If the electronic device is not moving, the process returns to step S502. If the electronic device is moving, it proceeds to step S506. In step S506, it is determined that the wireless connection between the electronic device and the fixed WiFi access point is strong. Whether the degree is less than a predetermined value. If the signal strength of the wireless connection is not less than the predetermined value, then return to step S502. If the signal strength of the wireless connection is less than the preset value, proceed to step S508. In step S508, the offset position (offset) of the data being transferred (i.e., the location at which the material is now downloaded) is calculated. For example, in step S508, it is determined whether the data is being transmitted by the wireless connection, and if so, the offset position of the data being transferred is calculated. In step S510, the wireless connection between the electronic device and the fixed WiFi access point is automatically interrupted, and the electronic device is automatically connected to a mobile WiFi access point accessible in the list of the electronic device. In step S512, data transfer is continued from the calculated offset position.

In the embodiment of the present invention, when the wireless module 106 of the electronic device 100 is communicating with a fixed WiFi access point and the electronic device 100 is away from the signal range of the fixed WiFi access point, the wireless module 106 at this time The received signal strength of the fixed WiFi access point is getting weaker and weaker. When the processing unit 102 determines that the signal strength of the fixed WiFi access point is less than a predetermined value, the processing unit 102 causes the wireless module 106 to calculate an offset position of the data in transit. Then, the processing unit 102 causes the wireless module 106 to automatically convert the wireless link from the fixed WiFi access point to the mobile WiFi access point provided by the mobile device (ie, the wireless module 106 automatically connects to the mobile WiFi access point). ). After the wireless module 106 establishes a connection with the mobile WiFi access point, the wireless module 106 continues to transmit data with the mobile WiFi access point from the previously recorded offset position.

The method of automatically converting an access point of the present invention allows an electronic device to not cause an interruption when using a wireless network. Traditionally, when an electronic device switches to another WiFi access point, it needs to wait until the original WiFi signal disappears or manually selects it. Take another WiFi access point to convert. The method provided by the invention allows the electronic device to determine whether it is necessary to convert the access point, and does not need to wait until the WiFi signal disappears to perform the conversion process. In addition, when the electronic device is originally connected to the mobile WiFi access point and moves to the signal range of the fixed WiFi access point, it can automatically switch to the fixed WiFi access point, which can not only reduce the provision of mobile WiFi access. The battery power consumed by the mobile device of the point can also make the data transmission speed faster. Through the automatic conversion access point method of the present invention, the user of the electronic device can use the wireless network through the WiFi access point regardless of whether it is in the company, at home or on the way.
