Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The terminology used in the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.

As shown in fig. 1, fig. 1 is a flowchart illustrating a wireless access method of a terminal according to an exemplary embodiment, which may be used in the terminal, and includes the following steps:

step 101, when a wireless network signal from an AP is scanned, extracting identification information in the wireless network signal.

In the disclosure, the terminal starts a wifi function, scans a wireless network signal sent by the AP, and detects whether the wireless network signal can be scanned.

The AP in the present disclosure may be a router or a terminal. The identification information in the present disclosure may be a Service Set Identifier (SSID) and a physical address, such as a Media Access Control (MAC) address, for uniquely representing the identity of the AP.

The router in the present disclosure, as an intelligent routing device, not only has a traditional routing function, but also may further include an independent operating system and a disk, where the size of the storage space of the disk may be flexibly set as required, for example, set to 1T; the terminal in the present disclosure may be any intelligent terminal having an internet access function, and may be specifically a mobile phone, a tablet computer, a Personal Digital Assistant (PDA), or the like. The terminal can access the router through the wireless local area network and access the server on the public network through the router.

In this disclosure, the terminal may scan the wireless network signal in an active scanning manner or a passive scanning manner. The active scanning refers to that a terminal actively sends a Probe message, such as a Probe Request (Probe Request) message, on a channel supported by the terminal to scan signals of a wireless network existing around, where the terminal sends the Probe Request message in a broadcast manner so as to be able to scan all the wireless networks around. The passive scanning means that the terminal does not actively send out a detection message, but passively receives a wireless network signal, namely a Beacon message (Beacon), periodically sent by the AP, so as to determine that a wireless network exists around.

When the terminal scans the wireless network signal, the SSID and the physical address in the wireless network signal are extracted, namely the identification information of the AP is obtained. In the steps of this disclosure, the terminal may further display an SSID list of the wireless networks that can be scanned.

Step 102, judging whether the identification information exists in a pre-stored AP information list.

In the present disclosure, the terminal may store the SSID and the physical address of the AP in which the user is interested in the AP information list in advance. The terminal can pre-establish an AP information list, when the terminal is associated with an AP, a user experiences a network provided by the AP, and the user judges whether the AP is an interested AP. The terminal may provide a function and an identifier for adding information of the current AP to the AP information list, and when an operation of adding to the AP information list by the user is detected, may extract an SSID and a physical address of the current AP and store the extracted SSID and physical address in the AP information list in correspondence.

And 103, associating to the current AP when the acquired identification information is judged to be in the AP information list.

In the step of the disclosure, the terminal compares the acquired SSID and physical address with those prestored in the AP information list, and determines whether the SSID and physical address are consistent. If the judgment result is that the current AP is the interested AP indicated in the AP information list, if the judgment result is that the current AP is not the interested AP indicated in the AP information list, the current AP is not associated with the current AP.

In some scenarios, coverage areas of multiple APs overlap, for example, in a case where multiple APs are connected to a wireless Controller (AC) to form a wireless service network, a terminal in the same area can scan wireless network signals from the multiple APs, and two or more APs in the multiple APs are likely to be interested APs of a user, so that the terminal can select between the multiple interested APs, and further, evaluation information of the user on the APs can be stored in an AP information list.

In the disclosure, after the terminal disconnects the AP associated therewith each time, the terminal may output an evaluation window for the user to input evaluation information for the AP. In practical applications, there are many factors for the user to assess the interested AP, which mainly include signal strength, coverage, and service quality of wireless network signals, for example, whether more services, such as wall-turning services, can be provided. The evaluation information may be an evaluation of the above-described aspects. The rating information may be presented on a star level to facilitate comparisons between APs. For example, for signal strength, five stars indicate very good signal strength, and three stars indicate normal signal strength; the rating information may also be represented numerically, with several numerical levels being preset for the user to choose from, for example, 10 for very good quality of service and 8 for good quality of service. And the terminal correspondingly stores the received evaluation information into the AP information list. In addition, the terminal may also store the priority level set by the user for each AP of interest in the AP information list.

In the present disclosure, for the above scenario, in a case where the terminal has associated the AP of interest, if a wireless network signal from another AP is scanned again, for convenience of description, the associated AP is hereinafter referred to as a first AP, and another AP scanned later is referred to as a second AP, the terminal extracts second identification information of the second AP and determines whether the second identification information exists in the AP information list, and when it is determined that the second identification information exists in the AP information list, the terminal may compare the first AP and the second AP, and determine whether to switch to the second AP according to a comparison result.

In the disclosure, the terminal may read the priorities of the first AP and the second AP from the AP information list, and determine which priority is higher, and if the priority of the first AP is higher, the terminal does not switch to be associated with the second AP; if the priority of the second AP is higher, the terminal switches to associate to the second AP.

In this disclosure, the terminal may further read first signal strength data of the first AP and second signal strength data of the second AP from the AP information list; judging which representative signal intensity of the two signal intensity data is larger; if the first signal intensity data is larger than the second signal intensity data, the terminal does not execute switching; and if the first signal strength data is not larger than the second signal strength data, the terminal switches to be associated to the second AP.

In the disclosure, the terminal may further obtain a first signal coverage of the first AP and a second signal coverage of the second AP from the AP information list; and judging which signal has larger coverage; if the first signal coverage is larger than the second signal coverage, the terminal does not execute switching; and if the first signal coverage range is not larger than the second signal coverage range, the terminal switches to be associated to the second AP.

In the present disclosure, the terminal may further obtain first quality of service data of the first AP from the AP information list, and obtain second quality of service data of the second AP; and judging which service quality data is more optimal; if the first service quality data is judged to be superior to the second service quality data, the terminal does not execute switching; and if the first service quality data is judged not to be superior to the second service quality data, the terminal is switched to be associated to the second AP.

In the present disclosure, the first AP and the second AP may not be compared, but the current signal strength of the first AP may be determined; comparing the current signal strength with a preset signal strength threshold value; if the current signal intensity of the first AP is judged to be larger than the signal intensity threshold value, the terminal does not execute switching; and if the current signal strength of the first AP is not greater than the signal strength threshold value, the terminal switches to be associated to the second AP.

In the disclosure, during the association between the terminal and the first AP, if other interested APs belonging to the AP information list are detected, the handover may not be performed according to the first-come-first-come principle until the association is disconnected from the first AP, and then it is determined whether to switch the association to the second AP.

As shown in fig. 2, fig. 2 is a schematic diagram illustrating a wireless access application scenario of a terminal according to an exemplary embodiment of the present disclosure. In the scenario shown in fig. 2, the following are included: millet smart phones and AP 1 and AP 2 as terminals.

In this scenario, the millet smartphone scans the first wireless network signal from the AP 1, the millet smartphone extracts the SSID and the physical address in the first wireless network signal, compares the extracted information with information prestored in the AP information list, and associates the extracted information with the AP 1 if it is determined that the extracted information exists in the AP information list. Along with the movement of the millet smart phone, the millet smart phone scans a second wireless network signal from the AP 2, the millet smart phone extracts the SSID and the physical address in the second network signal and compares the extracted information with the information in the AP information list, if the extracted information is judged to be in the AP information list, the priority of the AP 1 and the priority of the AP 2 are further extracted from the AP information list, and if the priority of the AP 1 is judged to be lower than the priority of the AP 2, the millet smart phone automatically releases the association with the AP 1 and associates the AP 1 with the AP 2.

By applying the embodiment provided by the disclosure, the terminal can be automatically connected to the AP which the user is interested in according to the AP information list set based on the preference of the user, manual intervention of the user is not needed, and the user experience is improved.
