Description

Wireless network connection method, electronic equipment and chip system

Technical Field

The present disclosure relates to the field of terminal technologies, and in particular, to a wireless network connection method, an electronic device, and a chip system.

Background

When the terminal device of the Android 10 operating system connects to the AP device by Wi-Fi (Wireless Fidelity ), the Android 10 operating system requires the terminal device to connect to the AP device using a random MAC address (Media Access Control Address ). For example, when a terminal device connects to an AP device for the first time, the terminal device connects to the AP device through a first MAC address, and after the configuration information (such as Wi-Fi name or encryption mode) of the AP device changes, when the terminal device needs to connect to the AP device again, the terminal device connects to the AP device through a random second MAC address, where the second MAC address is usually a different MAC address from the first MAC address.

The AP device uses the MAC address of the terminal device as the identifier of the distinguishing terminal device, so that in the case that the same terminal device is connected with the same AP device through different MAC addresses, the AP device may identify the same terminal device corresponding to the different MAC addresses as different terminal devices, which is inconvenient for the AP device to manage the terminal device.

Disclosure of Invention

The application provides a wireless network connection method, electronic equipment and a chip system, which solve the problems that in the prior art, the same terminal equipment is connected with the same AP equipment by adopting different MAC addresses, so that the AP equipment can identify the same terminal equipment corresponding to the different MAC addresses as different terminal equipment, and the management of the AP equipment on the terminal equipment is inconvenient.

In order to achieve the above purpose, the present application adopts the following technical scheme:

in a first aspect, an embodiment of the present application provides a wireless network connection method, including: the terminal equipment establishes wireless network connection with the wireless Access Point (AP) equipment through a first MAC address; the terminal equipment acquires a first AP equipment identifier sent by the AP equipment and determines the corresponding relation between the first MAC address and the first AP equipment identifier; wherein the first AP device identifier is configured to identify the AP device; and under the condition that the terminal equipment needs to establish wireless network connection with the AP equipment again and the configuration information of the AP equipment changes, the terminal equipment determines to establish wireless network connection with the AP equipment through the first MAC address based on the corresponding relation.

According to the wireless network connection method, the terminal equipment establishes wireless network connection with the AP equipment through the first MAC address, then the terminal equipment acquires the first AP equipment identifier which is sent by the AP equipment and used for equipment of the AP equipment, the corresponding relation between the first MAC address and the first AP equipment identifier is determined, when the terminal equipment needs to establish wireless network connection with the AP equipment again and the configuration information of the AP equipment changes, the terminal equipment determines to establish wireless network connection with the AP equipment through the first MAC address based on the corresponding relation, so that the terminal equipment still establishes wireless network connection with the AP equipment through the first MAC address under the condition that the configuration information of the AP equipment changes, and therefore the same MAC address can be adopted for the same terminal equipment when the same terminal equipment is in multiple wireless connection with the AP equipment, and the AP equipment can conveniently manage the terminal equipment based on the MAC address.

With reference to the first aspect, in some embodiments, the obtaining, by the terminal device, an AP device identifier sent by the AP device, and determining a correspondence between the first MAC address and the first AP device identifier includes: the terminal equipment acquires a first message sent by the AP equipment, wherein the first message comprises a first AP equipment identifier, and the first message is fed back to the terminal equipment by the AP equipment when the AP equipment tries to establish wireless network connection with the terminal equipment; and the terminal equipment establishes a corresponding relation between the first MAC address and the AP equipment identifier.

For example, the first message may be an association response Association Response message, the AP device may send Association Response a message including the first AP device identifier to the terminal device, and after the terminal device receives Association Response a message including the first AP device identifier sent by the AP device, the first AP device identifier is extracted from the Association Response message, so as to establish a correspondence between the first AP device identifier and the first MAC address.

It should be noted that, the Association Response message is a message used for Wi-Fi data transmission, but the embodiment of the application is not limited thereto, and for other types of wireless networks, a corresponding message may be used as the first message.

With reference to the first aspect, in some embodiments, the first AP device identification includes a basic service set identification BSSID of the AP device and a valid variation range of the BSSID; the terminal device establishes a corresponding relation between the first MAC address and the first AP device identifier, and the corresponding relation comprises the following steps: the terminal equipment determines the BSSID range of the AP equipment according to the BSSID of the AP equipment and the effective change range of the BSSID; and the terminal equipment establishes a corresponding relation between the first MAC address and the BSSID range of the AP equipment.

The BSSID is a basic service set identifier of the AP equipment, the AP equipment can be uniquely identified, and the terminal equipment can conveniently acquire the BSSID of the AP equipment through an AP hot spot of the AP equipment before wireless network connection is established between the terminal equipment and the AP equipment.

For example, the Association Response message may carry a vendor specific field, where the vendor specific field includes information such as a basic BSSID of the AP device and an effective variation range of the basic BSSID. For example, the vendor specific field may contain an Element ID (Element identification code) bit, a Length bit, and a Length-indeterminate bit. The base BSSID of the AP equipment and the effective variation range of the base BSSID form a first AP equipment identifier.

For example, the effective variation range of the BSSID is n, the terminal device may use the basic BSSID of the AP device as the first BSSID, and accumulate the end of the basic BSSID for n-1 times to obtain n BSSIDs corresponding to the AP device, which are used as the BSSID ranges of the AP device.

With reference to the first aspect, in some embodiments, the terminal device may acquire the identity of the AP device before re-establishing the wireless network connection with the AP device. Correspondingly, the terminal device determines to establish wireless network connection with the AP device through the first MAC address based on the correspondence relationship, including: after scanning a first BSSID of the AP equipment, the terminal equipment matches the first BSSID with the BSSID range; and if the first BSSID is the BSSID in the BSSID range, the terminal equipment establishes wireless network connection with the AP equipment through the first MAC address. Wherein the first BSSID is any one of one or more AP hotspots of the AP device.

In an application scenario, a database for storing correspondence between MAC addresses and AP device identifiers may be provided in a terminal device, where the database includes m correspondence relationships, each of which involves a MAC address and a plurality of BSSIDs, where the plurality of BSSIDs in each correspondence relationship corresponds to a same AP device, and the plurality of BSSIDs may correspond to a plurality of AP hotspots of the same AP device.

For example, when the terminal device scans an AP hotspot of the AP device each time it needs to establish a wireless network connection with the AP device, the terminal device obtains a BSSID of the AP device from the AP hotspot, matches the BSSID of the AP device with each BSSID in each corresponding relation in the database, and if the BSSID of the AP hotspot is one BSSID in the i (1. Ltoreq.i.ltoreq.m) corresponding relation, uses MACi in the i corresponding relation as an MAC address used for establishing a wireless network connection with the AP device corresponding to the AP hotspot.

For example, after the terminal device establishes a wireless network connection with the AP device through a MACj (1. Ltoreq.j. Ltoreq.m) address, the AP device sends a Association Response packet carrying BSSID information of the AP device to the terminal device, the terminal device extracts the BSSID of the AP device from the Association Response packet, establishes a correspondence between the BSSID of the AP device and the MACj address, and stores the correspondence in the database.

With reference to the first aspect, in some embodiments, the terminal device may obtain the identifier of the AP device after establishing a wireless network connection with the AP device. Correspondingly, the terminal device determines to establish wireless network connection with the AP device through the first MAC address based on the correspondence relationship, including: the terminal equipment establishes wireless network connection with the AP equipment through a second MAC address; the terminal equipment acquires a second AP equipment identifier sent by the AP equipment, wherein the second AP equipment identifier is used for identifying the AP equipment; the terminal equipment compares the first AP equipment identifier with the second AP equipment identifier; if the first AP equipment identifier corresponds to the same AP equipment with the second AP equipment identifier, the terminal equipment establishes wireless network connection with the AP equipment again through the first MAC address.

After the terminal device scans an AP hotspot of a certain AP device, a wireless network connection may be established between the terminal device and the AP device through a second MAC address, and then the AP device sends a second AP device identifier of the AP device to the terminal device, where the terminal device matches the second AP device identifier with the AP device identifiers in each corresponding relationship, so as to determine a target AP device identifier that represents the same AP device with the second AP device identifier, and then the terminal device determines a target MAC address corresponding to the target AP device identifier (that is, the first MAC address). If the target MAC address and the second MAC address are the same MAC address, the terminal equipment continues to keep the wireless network connection with the AP equipment, and if the target MAC address and the second MAC address are different MAC addresses, the terminal equipment reestablishes the wireless network connection with the AP equipment through the target MAC address.

In a second aspect, an embodiment of the present application provides a wireless network connection method, including: under the condition that wireless Access Point (AP) equipment and terminal equipment establish wireless network connection, the AP equipment generates a first AP equipment identifier for identifying the AP equipment; and the AP equipment sends the first AP equipment identifier to the terminal equipment.

According to the wireless network connection method, the terminal equipment establishes wireless network connection with the AP equipment through the first MAC address, the AP equipment generates the first AP equipment identifier for identifying the AP equipment and sends the first AP equipment identifier to the terminal equipment, the terminal equipment obtains the first AP equipment identifier, the corresponding relation between the first MAC address and the first AP equipment identifier is determined, when the terminal equipment needs to establish wireless network connection with the AP equipment again and the configuration information of the AP equipment changes, the terminal equipment determines to establish wireless network connection with the AP equipment through the first MAC address based on the corresponding relation, and therefore under the condition that the configuration information of the AP equipment changes, the terminal equipment still establishes wireless network connection with the AP equipment through the first MAC address, and therefore the same MAC address can be adopted for the same terminal equipment when the terminal equipment and the AP equipment are in wireless connection for a plurality of times, and management of the terminal equipment based on the MAC address is facilitated.

With reference to the second aspect, in some embodiments, the first AP device identification includes a basic service set identification BSSID of the AP device and a valid range of variation of the BSSID; the AP equipment sends the first AP equipment identifier to the terminal equipment, and the method comprises the following steps: and the AP equipment sends an association response Association Response message to the terminal equipment, wherein the Association Response message comprises a Basic Service Set Identifier (BSSID) of the AP equipment and an effective variation range of the BSSID.

Detailed Description

Embodiments of the present application are described below with reference to the accompanying drawings in the embodiments of the present application. The terminology used in the description of the embodiments of the application is for the purpose of describing particular embodiments of the application only and is not intended to be limiting of the application.

When a terminal device of the Android 10 operating system connects with an AP (Access Point) device by Wi-Fi (Wireless Fidelity ), the Android 10 operating system requires the terminal device to connect with the AP device using a random MAC address (Media Access Control Address ). For example, when a terminal device connects to an AP device for the first time, the terminal device connects to the AP device through a first MAC address, and after the configuration information of the AP device changes, for example, the Wi-Fi name or encryption mode of the AP device changes, when the terminal device connects to the AP device again, the terminal device connects to the AP device through a second MAC address different from the first MAC address. The AP device uses the MAC address of the terminal device as the identifier for distinguishing the terminal device, so that the AP device may identify the terminal device corresponding to the first MAC address and the terminal device corresponding to the second MAC address as devices of different terminals.

Illustratively, the SSID (Service Set Identifier, service set identification) of the AP device is named SSID1, the password is 111111111, and the terminal device connects to the AP device using the MAC1 address (e.g., 11:22:33:44:55:66), at which point the AP device identifies the terminal device as terminal device 1. The user modifies the SSID name of the AP device to SSID2 and the password to 22222222, and after the terminal device scans to the AP device of SSID2, the terminal device connects to the AP device using a random MAC2 address (e.g., 1a:2a:3a:4a:5a:6 a). The AP device then recognizes the terminal device as terminal device 2. Therefore, the same terminal equipment is connected with the AP equipment through different MAC addresses, so that the AP equipment can identify the same terminal equipment corresponding to different MAC addresses as different terminal equipment, and management of the terminal equipment by the AP equipment is inconvenient.

In another scenario, when the terminal device is connected to the AP device through the first MAC address, the user may add the first MAC address to the MAC address list of the AP device to control whether the terminal device corresponding to the MAC address can be connected to the AP device, and after the configuration information of the AP device changes, the terminal device is connected to the AP device through the second MAC address, and since the second MAC address is different from the first MAC address, the MAC address filter list does not include the second MAC address, so that the AP device cannot limit the terminal device to connect to the AP device.

Illustratively, the SSID of the AP device is named SSID1 and the password is 111111111. The terminal device uses the MAC1 address (for example, 11:22:33:44:55:66) to connect to the AP device, where the AP device adds the MAC1 address to a MAC address list, where the MAC address list is used for the AP device to control whether the terminal device corresponding to the MAC address can connect to the AP device. The user modifies the SSID name of the AP device to SSID2 and the password to 22222222, and after the terminal device scans to the AP device of SSID2, the terminal device connects to the AP device using a random MAC2 address (e.g., 1a:2a:3a:4a:5a:6 a). Because the MAC address list does not include the MAC2 address, the AP device may not control the network connection of the terminal device to the AP device.

Based on the above problems, the embodiments of the present application provide a wireless network connection method, an electronic device, and a chip system, where a terminal device establishes a wireless network connection with an AP device through a first MAC address, then the terminal device obtains a first AP device identifier for the AP device sent by the AP device and determines a correspondence between the first MAC address and the first AP device identifier, and in a case where the terminal device needs to establish a wireless network connection with the AP device again and configuration information of the AP device changes, the terminal device determines, based on the correspondence, to establish a wireless network connection with the AP device through the first MAC address, so that in a case where configuration information of the AP device changes, the terminal device still establishes a wireless network connection with the AP device through the first MAC address, so that for the same terminal device, when performing multiple wireless connections with the AP device, the same MAC address can be adopted, and the AP device identifies the terminal device corresponding to the first MAC address and the terminal device corresponding to the second MAC address as the same terminal device. Also, in the case where the first MAC address is added to the MAC address list of the AP device, the AP device can control whether the terminal device can connect to the AP device because the terminal device is still connected to the AP device through the first MAC address. Therefore, the method provided by the embodiment of the application can facilitate the AP equipment to manage the terminal equipment based on the MAC address.

Wherein, each terminal device 100 can establish a wireless network connection with the AP device 200 through a MAC address, the AP device 200 implements management on each terminal device 100 based on the MAC address, for example, the AP device 200 identifies each terminal device 100 based on the MAC address, or the AP device 200 authorizes the corresponding terminal device 100 to connect to the AP device 200 based on the MAC address, or the AP device 200 restricts the corresponding terminal device 100 to connect to the AP device 200 based on the MAC address.

After the configuration information of the AP device 200 changes, for example, the SSID name or encryption scheme of the AP device 200 changes, if the terminal device 100 needs to establish a wireless network connection with the AP device 200 again, the terminal device 100 establishes a wireless network connection with the AP device 200 again through a first MAC address used for establishing a wireless network connection with the AP device 200 before.

By way of example, the AP device 200 may be an electronic device capable of generating AP hotspots, such as a router, a switch, a wireless network card, a modem, etc., and the specific type of the AP device 200 is not limited in the embodiments of the present application.

The following describes a wireless network connection method provided in the embodiment of the present application.

Referring to fig. 4, fig. 4 is a flowchart of a wireless network connection method according to an embodiment of the present application, where the method includes:

step 101, the terminal equipment establishes wireless network connection with the wireless Access Point (AP) equipment through the first MAC address.

The AP device may generate one or more AP hotspots, where each AP hotspot corresponds to an SSID. For example, after scanning the SSID of a certain AP hotspot of the AP device, the terminal device may send a message to the AP device to inform the AP device that the terminal device establishes a wireless network connection with the AP hotspot through the first MAC address.

For example, after scanning the SSID of a certain AP hotspot of the AP device, the terminal device sends a Association Response packet to the AP device, and the AP device may determine according to the Association Response packet: the terminal equipment establishes wireless network connection with the AP hot spot through the first MAC address.

It should be noted that the Association Response message is only an exemplary illustration, but not limited thereto, and other messages capable of implementing the above-mentioned functions are also included in the protection scope of the present application.

By way of example, the wireless network may be Wi-Fi, bluetooth, loRa, zigbee, etc., and the embodiments of the present application do not limit the specific type of wireless network.

Step 102, the AP device generates a first AP device identifier for identifying the AP device, and sends the first AP device identifier to the terminal device.

The first AP device identifier is used to identify the AP device, and the terminal device may determine, according to the first AP device identifier, the AP device corresponding to the first AP device identifier. After the terminal device establishes wireless network connection with the AP device through the first MAC address, the AP device generates a first AP device identifier for identifying the AP device and sends the first AP device identifier to the terminal device.

In some embodiments, the AP device may send a first message including a first AP device identifier to the terminal device, where the first message is a message that the AP device feeds back to the terminal device when the terminal device establishes a wireless network connection with the AP device.

Illustratively, the first message may be an association response Association Response message, and the AP device may send Association Response a message including the first AP device identifier to the terminal device. The details of Association Response are described later, and will not be repeated here.

It should be noted that, the Association Response message is a message used for Wi-Fi data transmission, but the embodiment of the application is not limited thereto, and for other types of wireless networks, a corresponding message may be used as the first message, which is all within the protection scope of the application.

Step 103, the terminal equipment acquires a first AP equipment identifier sent by the AP equipment, and determines a corresponding relation between the first MAC address and the first AP equipment identifier.

In some embodiments, after the terminal device obtains the first packet, the terminal device extracts the first AP device identifier from the first packet, and the terminal device establishes a correspondence between the first MAC address and the first AP device identifier. The terminal device may determine an AP device corresponding to the first AP device identifier, thereby determining a correspondence between the AP device and the first MAC address.

In some embodiments, the AP device may send a first message including a first AP device identifier to the terminal device, where the first message is a message that the AP device feeds back to the terminal device when the terminal device establishes a wireless network connection with the AP device. After the terminal equipment acquires the first message, the first AP equipment identifier is extracted from the first message, and the terminal equipment establishes a corresponding relation between the first MAC address and the first AP equipment identifier. The terminal device may determine an AP device corresponding to the first AP device identifier, thereby determining a correspondence between the AP device and the first MAC address.

Exemplary, after receiving a Association Response message containing a first AP device identifier sent by an AP device, the terminal device extracts the first AP device identifier from the Association Response message, so as to establish a correspondence between the first AP device identifier and the first MAC address.

The terminal device may establish a correspondence between the AP device identifiers of the AP devices that have established the wireless network connection with the terminal device and the corresponding MAC addresses. For example, the terminal device establishes a wireless network connection with the first AP device through the MAC1 address, the terminal device establishes a wireless network connection with the second AP device through the MAC2 address, the terminal device establishes a wireless network connection with the third AP device through the MAC3 address, the AP device of the first AP device is identified as SSID1, the AP device of the second AP device is identified as SSID2, and the AP device of the third AP device is identified as SSID3, and the correspondence established by the terminal device may include a correspondence between the MAC1 address and SSID1, a correspondence between the MAC2 address and SSID2, and a correspondence between the MAC3 address and SSID 3.

The first AP device identifier may be, for example, a BSSID ((basic service set identifier, basic service set identifier) of the AP device, but embodiments of the present application are not limited to the first AP device identifier being a BSSID of the AP device, and the first AP device identifier may be any identifier capable of identifying the AP device.

Step 104, when the terminal device needs to establish wireless network connection with the AP device again and the configuration information of the AP device changes, the terminal device determines to establish wireless network connection with the AP device through the first MAC address based on the corresponding relationship.

The configuration information of the AP device includes, but is not limited to: an AP hotspot name, an encryption manner, and the like, which are exemplary, where the AP hotspot name may specifically be an SSID of an AP hotspot of the AP device, and the encryption manner may specifically be a password corresponding to the SSID of the AP hotspot. The configuration information of the AP device is changed, including but not limited to: the SSID of the AP hotspot of the AP device changes, and/or the password corresponding to the SSID of the AP hotspot changes. For example, the SSID of the AP hotspot of the AP device changes from SSID1 to SSID2, and the password corresponding to the SSID of the AP hotspot changes from 111111111 to 222222222.

For example, in the case that the terminal device needs to establish the wireless network connection with the AP device again and the configuration information of the AP device changes, the method specifically may be: after the terminal equipment scans the AP hot spot of the AP equipment, wireless network connection is required to be established with the AP equipment, if the identification of the current AP equipment is the same as the identification of a certain AP equipment connected before the terminal equipment, the current AP equipment and the certain AP equipment are the same AP equipment, if the configuration information of the current AP equipment is different from the configuration information of the certain AP equipment, the terminal equipment is required to establish wireless network connection with the AP equipment again, and the configuration information of the AP equipment is changed. In one scenario, after the terminal device establishes a wireless network connection with the AP device through the first MAC address, the AP device sends a first AP device identifier to the terminal device, the terminal device establishes a correspondence between the first AP device identifier and the first MAC address, and then configuration information of the AP device changes, for example, an AP hotspot name and/or an encryption manner of the AP device changes, and the terminal device needs to establish a wireless network connection with the AP device again.

After the terminal equipment scans a certain AP hot spot, the AP hot spot is used for acquiring a first identifier of AP equipment corresponding to the AP hot spot, the first identifier is matched with a stored historical AP equipment identifier, and the historical AP equipment identifier can be the identifier of one or more AP equipment which is connected with the terminal equipment through a wireless network. The terminal equipment determines a first historical AP equipment identifier which represents the same AP equipment with the first identifier, then determines an MAC address corresponding to the first historical AP equipment identifier according to the stored corresponding relation, and establishes wireless network connection with the AP equipment again through the determined MAC address.

According to the wireless network connection method, the terminal equipment establishes wireless network connection with the AP equipment through the first MAC address, the AP equipment generates the first AP equipment identifier for identifying the AP equipment and sends the first AP equipment identifier to the terminal equipment, then the terminal equipment acquires the first AP equipment identifier, and determines the corresponding relation between the first MAC address and the first AP equipment identifier, when the terminal equipment needs to establish wireless network connection with the AP equipment again and the configuration information of the AP equipment changes, the terminal equipment determines to establish wireless network connection with the AP equipment through the first MAC address based on the corresponding relation, so that the terminal equipment still establishes wireless network connection with the AP equipment through the first MAC address under the condition that the configuration information of the AP equipment changes, and therefore the same MAC address can be adopted for the same terminal equipment when the same terminal equipment performs multiple wireless connection with the AP equipment, and management of the terminal equipment based on the MAC address is facilitated.

In a possible implementation manner, the first AP device identifier may include a BSSID of the AP device and an effective variation range of the BSSID, and the establishing, by the terminal device in step 103, a correspondence between the first MAC address and the first AP device identifier may include: the terminal equipment determines the BSSID range of the AP equipment according to the BSSID of the AP equipment and the effective variation range of the BSSID; and the terminal equipment establishes a corresponding relation between the first MAC address and the BSSID range of the AP equipment. The BSSID is a basic service set identifier of the AP equipment, the AP equipment can be uniquely identified, and the terminal equipment can conveniently acquire the BSSID of the AP equipment through an AP hot spot of the AP equipment before wireless network connection is established between the terminal equipment and the AP equipment.

For example, the effective variation range of the BSSID is n, the terminal device may use the basic BSSID of the AP device as the first BSSID, and accumulate the end of the basic BSSID for n-1 times to obtain n BSSIDs corresponding to the AP device, which is used as the BSSID range of the AP device. For example, the BSSID of the AP device is 11:22:33:44:55:66, and the effective variation range of the BSSID is 5, and then the terminal device takes 11:22:33:44:55:66 as the first BSSID, and adds up the end of 11:22:33:44:55:66 by 4 times 1, to obtain 11:22:33:44:55:67, 11:22:33:44:55:68, 11:22:33:44:55:69, and 11:22:33:44:55:6a, and takes these BSSIDs as the BSSID ranges of the AP device, that is, the BSSID ranges of the AP device are 11:22:33:44:55:66 to 11:22:33:44:55:6a.

In a possible implementation manner, the first message may include a field carrying the identifier of the first AP device, for example, the first message is a Association Response message, and the Association Response message includes a vendor specific field, where the vendor specific field includes information such as a basic BSSID of the AP device and a valid variation range of the basic BSSID.

For example, the vendor specific field may include an Element ID (Element identification code) bit, a Length bit, and a Length-indeterminate bit, and specific information of the vendor specific field is shown in table 1.

TABLE 1 vendor specific field

Referring to table 1, element ID bit 221 indicates Wi-Fi access protection, an element used for WPA (Wi-Fi Protected Access, wi-Fi network security access). The Length bit indicates the Length of the above-mentioned Length-indefinite bit, and the values of the Length bits may be 10 if the 2 bits to 11 bits in table 1 are the above-mentioned Length-indefinite bits. In table 1, the above-mentioned indefinite-length bits include an OUI (Organizationally unique identifier, organization unique identifier) of 3 bits in length, a base BSSID of 6 bits in length, and a valid BSSID of 1 bit in length. OUI represents the meaning represented by bits 5 to 11, with OUI in table 1 being 00E0FF, representing a Wi-Fi address. The basic BSSID represents the basic BSSID of the AP device, e.g., 11:22:33:44:55:66. The effective BSSID represents an effective variation range of a basic BSSID of the AP device, where the effective BSSID in table 1 is 5, and represents that the effective variation range of the basic BSSID of the AP device is 5, that is, the BSSID range of the AP device is 11:22:33:44:55:66-11:22:33:44:55:6a, and the BSSIDs corresponding to 11:22:33:44:55:66-11:22:33:44:55:6a are all corresponding to the AP device and are used for identifying the AP device.

In one possible implementation, the terminal device may obtain the identity of the AP device before re-establishing the wireless network connection with the AP device. Correspondingly, the determining, by the terminal device in step 104, to establish a wireless network connection with the AP device through the first MAC address based on the correspondence may include: after scanning a first BSSID of the AP equipment, the terminal equipment matches the first BSSID with the BSSID range; if the first BSSID is the BSSID in the BSSID range, the terminal equipment establishes wireless network connection with the AP equipment through the first MAC address. Wherein the first BSSID is any one of one or more AP hotspots of the AP device.

For example, when the terminal device scans that the AP hotspot needs to establish a wireless network connection with the AP hotspot, the terminal device may obtain a first BSSID of the AP device corresponding to the AP hotspot from the AP hotspot, and then match the first BSSID with the BSSID range, and if the first BSSID is one BSSID in the BSSID range, the terminal device establishes a wireless network connection with the AP device through a first MAC address having a corresponding relationship with the BSSID.

For example, the BSSID range stored in the terminal device is 11:22:33:44:55:66-11:22:33:44:55:6 a, and 11:22:44:55:66-11:22:33:44:55:6 a corresponds to the MAC1 address, after the terminal device scans the AP hotspot, the BSSID of the AP device obtained from the AP hotspot is 11:22:33:44:55:68, and since 11:22:33:44:55:68 is one BSSID of 11:22:33:44:55:66-11:22:33:44:55:6 a, the terminal device establishes a wireless network connection with the AP device through the MAC1 address. If the BSSID of the AP device obtained from the AP hotspot by the terminal device is 11:22:33:44:55:73, the terminal device establishes a wireless network connection with the AP device through the random MAC address because 11:22:33:44:55:73 is not one BSSID of 11:22:33:44:55:66-11:22:33:44:55:6 a.

In an application scenario, a database for storing a correspondence between a MAC address and an AP device identifier may be provided in the terminal device, where the correspondence between the MAC address and the AP device identifier stored in the database is shown in table 2.

Table 2 table of correspondence between MAC addresses and AP device identifications

	MAC address	BSSID range
			1	MAC1	11:22:33:44:55:66～11:22:33:44:55:6a
2	MAC2	11:22:33:44:55:73～11:22:33:44:55:7a
			…	…	…
m	MACm	11:22:33:44:55:24～11:22:33:44:55:29

In table 2, an AP device identifier is illustrated as a BSSID. The table 2 contains m (1 is less than or equal to m) corresponding relations, each corresponding relation relates to a MAC address and a plurality of BSSIDs, the plurality of BSSIDs in each corresponding relation correspond to the same AP device, and the plurality of BSSIDs can correspond to a plurality of AP hotspots of the same AP device.

In an application scenario, when a terminal device establishes a wireless network connection with an AP device 1 for the 1 st time, an AP hotspot scanned by the terminal device to the AP device obtains a first BSSID of the AP device from the AP hotspot, and the terminal device compares the first BSSID of the AP device with the BSSID of the AP device stored in the database. Because the BSSID corresponding to the first BSSID does not exist in the database, the terminal equipment establishes wireless network connection with the AP equipment 1 through the random MAC1 address, the AP equipment sends a Association Response message carrying the BSSID of the AP equipment to the terminal equipment, the terminal equipment extracts the BSSID of the AP equipment from the Association Response message, establishes a correspondence between the BSSID of the AP equipment and the MAC1 address, and stores the correspondence in the database.

When the first (l is more than or equal to 2) time of the terminal equipment establishes wireless network connection with the AP equipment 1, configuration information of the AP equipment 1 changes at the moment, an AP hot spot scanned by the terminal equipment to the AP equipment acquires a first BSSID of the AP equipment from the AP hot spot, an MAC1 address is determined from a corresponding relation in a database according to the acquired first BSSID of the AP equipment, and wireless network connection is established with the AP equipment 1 through the MAC1 address. At this time, the AP device 1 sends a Association Response packet carrying the BSSID of the AP device to the terminal device, and the terminal device extracts the BSSID of the AP device from the Association Response packet, and since the BSSID extracted at this time already exists in a certain correspondence in the database, the correspondence of the BSSID of the AP device to the MAC1 address may not be established.

In yet another possible implementation, the terminal device may obtain the identity of the AP device after establishing a wireless network connection with the AP device. Correspondingly, the determining, by the terminal device in step 104, to establish a wireless network connection with the AP device through the first MAC address based on the correspondence may include: the terminal equipment establishes wireless network connection with the AP equipment through a second MAC address; the terminal equipment acquires a second AP equipment identifier sent by the AP equipment, wherein the second AP equipment identifier is used for identifying the AP equipment; the terminal equipment compares the first AP equipment identifier with the second AP equipment identifier; if the first AP equipment identifier corresponds to the same AP equipment with the second AP equipment identifier, the terminal equipment establishes wireless network connection with the AP equipment again through the first MAC address.

After the terminal device scans an AP hotspot of a certain AP device, a wireless network connection may be established between the terminal device and the AP device through a second MAC address, and then the AP device sends a second AP device identifier of the AP device to the terminal device, and the terminal device matches the second AP device identifier with the AP device identifiers in each corresponding relationship, thereby determining a target AP device identifier that represents the same AP device with the second AP device identifier, and then the terminal device determines a target MAC address corresponding to the target AP device identifier (that is, the first MAC address in step 101). If the target MAC address and the second MAC address are the same MAC address, the terminal equipment continues to keep the wireless network connection with the AP equipment, and if the target MAC address and the second MAC address are different MAC addresses, the terminal equipment reestablishes the wireless network connection with the AP equipment through the target MAC address.

In one application scenario, when a terminal device connects to the AP device through a first MAC address, the AP device identifies the terminal device based on the first MAC address and manages the terminal device, for example, allows the terminal device to connect to the AP device or does not allow the terminal device to connect to the AP device. After the configuration information of the AP equipment changes, when the terminal equipment needs to be connected with the AP equipment again, the terminal equipment determines to be connected with the AP equipment through the first MAC address according to the first AP equipment identifier of the AP equipment and the corresponding relation between the MAC address in the database and the AP equipment identifier IDE, and the terminal equipment is connected with the AP equipment through the same first MAC address before and after the terminal equipment, so that the terminal equipment corresponding to the same first MAC address is identified as the same terminal equipment by the AP equipment, and the management of the terminal equipment is facilitated.

In still another application scenario, when the terminal device is connected to the AP device through the first MAC address, the user may add the first MAC address to the MAC address filtering list of the AP device, so as to limit the terminal device corresponding to the first MAC address to connect to the AP device, and the terminal device corresponding to the MAC address outside the MAC address white list may connect to the AP device. After the configuration information of the AP device changes, when the terminal device needs to connect to the AP device again, the terminal device determines that the terminal device is connected to the AP device through the first MAC address according to the first AP device identifier of the AP device and the corresponding relationship between the MAC address in the database and the AP device identifier IDE, and because the first MAC address exists in the MAC address filtering list, the AP device can limit the terminal device to connect to the AP device.

In yet another application scenario, when the terminal device is connected to the AP device through the first MAC address, the user may add the first MAC address to the MAC address white list of the AP device, so as to allow the terminal device corresponding to the first MAC address to connect to the AP device, and a MAC address outside the MAC address white list cannot connect to the AP device. After the configuration information of the AP device changes, when the terminal device needs to connect to the AP device again, the terminal device determines to connect to the AP device through the first MAC address according to the first AP device identifier of the AP device and the correspondence between the MAC address in the database and the AP device identifier IDE, and because the first MAC address exists in the MAC address white list, the AP device allows the terminal device to connect to the AP device.
