Problems solved by technology

In this way, when searching for access points, not only the search success rate is low, but also extra power consumption will be brought to the terminal device every time the search is performed. Taking mobile phones as an example, this method of searching for access points will bring 10mA power consumption

Embodiment 1

[0054] figure 1 It is a schematic flowchart of a wireless access method provided by an embodiment of the present invention.

[0055] like figure 1 As shown, the method may include the following steps:

[0056] S101: Obtain current location information of the terminal.

[0057]In the embodiment of the present invention, the trigger condition of this step is the activation of the wireless transmission module, that is, the current location information of the terminal is obtained when the wireless transmission module is activated. When obtaining the current location information of the terminal, the terminal can be positioned by using the positioning method of the wireless transmission module itself, such as base station positioning, or by using other positioning methods, such as GPS positioning.

[0058] S102: Search for a wireless access point corresponding to the current location information in a set of pre-established correspondences between location information and wireless...

Embodiment 2

[0066] figure 2 It is a schematic flowchart of another wireless access method provided by an embodiment of the present invention.

[0067] like figure 2 As shown, the method may include the following steps:

[0068] S201: Determine whether the terminal is in the wireless access point search / display interface;

[0069] When the wireless transmission module of the terminal is turned on, it is necessary to confirm the control mode of the wireless transmission module. If the terminal is in the wireless access point search / display interface, it is in the user operation state. At this time, search and wireless access need to be performed according to the user operation. And when the terminal is not in the wireless access point search / display interface, S202 may be performed.

[0070] S202: Position the terminal, and obtain current location information of the terminal.

[0071] When obtaining the current location information of the terminal, a positioning method such as base st...

Embodiment 3

[0095] In other embodiments of the present invention, when the terminal has not performed wireless access before the current location, there is no set of pre-established correspondence between location information and wireless access points. Therefore, on the basis of the above two embodiments, the present invention also provides a third wireless access method, such as Figure 5 As shown, it is a schematic flowchart of the third wireless access method provided by the present invention.

[0096] like Figure 5 As shown, the method may also include the following steps:

[0097] S501: Search for all wireless access points at the current location, and initiate establishment of a wireless connection between the terminal and the wireless access points in the search result.

[0098] After step S102, when the search result shows that there is no wireless access point corresponding to the current location information, at this time, it indicates that the terminal has not performed wir...

Abstract

The invention discloses a wireless access method and an electronic device using the same. The method comprises the steps of obtaining current position information of a terminal when a wireless transmission module of the terminal is started; searching a wireless access point corresponding to the current position information in a pre-established corresponding relation set of position information and wireless access points; and launching establishment of wireless connection between the terminal and the wireless access point when the wireless access point corresponding to the current position information exists. Compared with the prior art, according to the wireless access method, users do not need to search all wireless access points at the position where the terminal is located prior to wireless access of the terminal, and waiting time for wireless access is reduced; besides, the wireless access point is searched only from the pre-established corresponding relation set of the position information and the wireless access points during searching, a search range of the wireless access point is reduced, electric quantity consumed by a terminal device during wireless access is reduced, and the search success rate of the wireless access point can be improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a wireless access method and electronic equipment applying the method. Background technique [0002] Wi-Fi is a technology that can wirelessly connect terminals such as personal computers and handheld devices (such as PDAs and mobile phones) to the network, so that the terminals can get rid of the restrictions of network cables, which greatly facilitates the terminals to access the Internet. [0003] However, the current access strategy after the Wi-Fi on the terminal device is turned on is: after the terminal is awakened, it will try to search for an access point, and if no access point is currently searched, it will try to search again at regular intervals, such as 20 seconds. Search until an accessible point is found or the device goes to sleep. In this way, when searching for access points, not only the search success rate is low, but also extra power consumption will...
