Optionally, when a plurality of wireless access points appear in the scanning result, one or more wireless access points with the optimal signal strength may be selected as the wireless access point to be acquired.
And S102, judging whether the wireless connection with the wireless access point in the current local area environment can be established or not according to the prestored connection information of the wireless access point.
According to the existing connection mechanism of the wireless network of the terminal, the connection information of the wireless access points which have already established the wireless connection is stored, and when the wireless access points which have already established the wireless connection before are obtained, the terminal can automatically establish the wireless connection with the wireless connection according to the stored connection information. The connection information of the prestored wireless access points includes the above-mentioned connection information of the wireless access points which have established wireless connections.
Specifically, the pre-stored connection information of the wireless access point includes a name of the wireless access point, a decryption method of the wireless access point, and/or a priority of the wireless access point.

Specifically, whether the local area environment where the terminal is currently located is a strange environment or not is judged by means of a mechanism for automatically scanning the wireless access point, and the low-power-consumption Bluetooth scanning is started only in the strange environment, so that the scanning times are greatly reduced, and the power consumption is saved.
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating another method for acquiring bluetooth broadcast information according to an embodiment of the present invention; in fig. 2, the processing of the bluetooth broadcast information after the bluetooth broadcast information is acquired and a series of measures taken to reduce power consumption when the terminal acquires the bluetooth broadcast information are described in detail.
S201, acquiring a wireless access point in the current local area environment.
Specifically, the terminal scans through a mechanism for automatically scanning the wireless access point, which is set by an existing terminal system, to obtain the wireless access point in the current local area environment.
S202, judging whether to establish wireless connection with the wireless access point in the current local area environment according to the prestored connection information of the wireless access point.
Specifically, when one or more wireless access points are acquired. The name of the acquired wireless access point can be associated and compared with the prestored connection information of the wireless access point, and when the prestored connection information contains the connection information corresponding to the name, whether a connection relation with the wireless access point in the current local area environment is established or not is judged according to the prestored connection information of the wireless access point.
S203, if not, starting the low-power Bluetooth scanning in the current local area environment.
As an alternative implementation manner, when the terminal is in a strange environment, the strange environment is consistent with the strange environment introduced in the step S103 executed in the first embodiment. The terminal starts a low-power-consumption Bluetooth technology to scan so as to acquire Bluetooth broadcast information which is sent by a broadcast server and is released through a low-power-consumption Bluetooth protocol broadcast channel, wherein the Bluetooth broadcast information released through the low-power-consumption Bluetooth protocol broadcast channel can be advertisement, latest preferential activity or latest social news and other information which are directionally pushed by some merchants, and can also be connection information of a wireless access point.
S204, when the Bluetooth broadcast information issued by the low-power-consumption Bluetooth protocol broadcast channel is scanned, the Bluetooth broadcast information is acquired.
As an optional implementation manner, since the terminal has certain mobility, in order to ensure that more terminals can scan the bluetooth broadcast information sent by each merchant and distributed through the low power consumption bluetooth protocol broadcast channel, the broadcast server for sending the bluetooth broadcast information distributed through the low power consumption bluetooth protocol broadcast channel may set a time interval for sending the broadcast information, that is, the broadcast information is sent once every other time interval, so that the terminal can smoothly receive the broadcast information sent by the broadcast server; the time interval may be determined according to the situation, or the terminal may acquire the broadcast information once the terminal starts bluetooth low energy scanning. The invention is not limited.
When the Bluetooth broadcast information published by the low-power-consumption Bluetooth protocol broadcast information is scanned to be advertisement information, marketing information, directory information or menu information, judging whether the published Bluetooth broadcast information is received Bluetooth broadcast information; and if the issued Bluetooth broadcast information is judged to be the unreceived Bluetooth broadcast information, acquiring the issued Bluetooth broadcast information. And if the issued Bluetooth broadcast information is judged to be the received Bluetooth broadcast information, giving up receiving the issued Bluetooth broadcast information.
S205, when the wireless connection with the wireless access point in the local area environment can not be established according to the acquired Bluetooth broadcast information, deleting the acquired Bluetooth broadcast information and acquiring the wireless access point in the local area environment again.
As an optional implementation manner, when the bluetooth broadcast information issued by the terminal through the low power consumption bluetooth protocol broadcast channel is the connection information of the wireless access point, the terminal may access the external data network resource by using the wireless access point after establishing wireless connection with the corresponding wireless access point according to the connection information. When the terminal is prompted to establish connection failure after sending the connection request, the terminal can select to continue sending the connection request until the number of times of sending the connection request reaches a preset threshold value, the terminal can delete the acquired Bluetooth broadcast information and continue scanning to acquire the wireless access point. The threshold value may be set by the user or preset by the terminal system. Further, when the number of times that the terminal scans to acquire the wireless access point reaches a preset threshold value, the terminal may also prompt the user to close the current scanning mechanism, so as to avoid wasting power consumption. The above threshold value may be 3 times, 6 times, or more, but it is not preferable to set the value too large in order to save power consumption.
As an optional implementation manner, since the terminal may be in the same local area network for a long time, or the broadcast server for sending the bluetooth broadcast information sends the same bluetooth broadcast information at regular intervals, in order to not cause a greater load to the storage system of the terminal, the terminal should perform a determination on the acquired bluetooth broadcast information, and determine whether the acquired bluetooth broadcast information has been received before. Such as: the method comprises the steps that a terminal A is always located in a restaurant in a certain time period, due to the fact that a broadcast server used for sending Bluetooth broadcast information in the restaurant automatically sends latest preferential activities of the restaurant at regular time intervals, when the time interval that the terminal A stays in the restaurant is longer than the time interval that the broadcast server used for sending the Bluetooth broadcast information in the restaurant automatically sends the latest preferential activities, if the terminal does not judge whether the acquired Bluetooth broadcast information is received; not processing the acquired bluetooth broadcast information may cause the terminal to repeatedly acquire the same broadcast information.
In the embodiment of the invention, when the acquired Bluetooth broadcast information is the connection information of the wireless access point, the terminal can send a connection request to the wireless access point corresponding to the connection information according to the pre-stored connection information; and when the connection is failed to be established, the terminal can judge whether to continue to scan and acquire the wireless access point according to a preset threshold value. By implementing the embodiment of the invention, the scanning mechanism of the terminal can be flexibly managed through setting the threshold value, so that the effect of reducing power consumption can be achieved.

A wlan scanning unit 41, configured to initiate wlan scanning in a local environment where the wlan is currently located.
At present, in many public or private occasions, in order to facilitate the public or specific users to experience the superiority of the wireless network anytime and anywhere, a wireless local area network is set up in a specific local area environment, and one or more wireless access points are correspondingly set up for the terminals to access and establish connection. The existing terminal sets an automatic scanning mechanism on the system, so that the latest wireless access point can be conveniently obtained anytime anywhere in time, and the terminal can conveniently establish connection with the latest wireless network through the wireless access point.
Specifically, when detecting that the geographic location of the terminal is changed, the wireless local area network scanning unit 41 may start local area network scanning, where the change of the geographic location may select a certain reference object, and perform determination based on the selected reference object, where the selected reference object may be a certain building with a landmark in the city where the terminal is located, or may be set by the user, for example: where the user lives. The invention is not limited to the specific selection of the reference substance.
