technical field

The embodiments of the present application relate to the field of communication technologies, and in particular, to a method and device for obtaining an IP address.

Background technique

With the development of science and technology, more and more electronic devices (such as mobile phones, notebook computers, etc.) perform wireless communication through wireless fidelity (Wireless Fidelity, WIFI) technology. In the process that the electronic device performs wireless communication through the WIFI technology, the electronic device needs to obtain an IP address, and perform network connection through the Internet Protocol Address (Internet Protocol Address, IP) address.

Currently, when an electronic device acquires an IP address, it needs to broadcast a request message to request to acquire the IP address. Afterwards, at least one wireless access point (Wireless Access Point, AP) can provide an IP address to the electronic device. Next, the electronic device may select an IP address from a plurality of IP addresses, and broadcast a message packet to indicate that the electronic device has accepted an IP address. The AP can then send a response message to the electronic device.

However, in the above technical solution, the electronic device needs to complete multiple interactions with the AP before it can obtain the IP address. Not only is the process more cumbersome, but also the speed of obtaining an IP address is slow.

SUMMARY OF THE INVENTION

The present application provides a method and an electronic device for obtaining an IP address, which can simplify the interaction process between the electronic device and the AP, and improve the speed at which the electronic device obtains the IP address.

In a first aspect, the present application provides a method for obtaining an IP address.

In this method, the electronic device establishes a connection with the AP. Wherein, after the electronic device establishes a connection with the AP, the AP can assign an IP address to the electronic device. After that, the AP may broadcast a preset beacon Beacon frame, where the preset Beacon frame includes indication information, where the indication information is used to indicate that the AP has the ability to actively send the IP address allocated by the AP to the electronic device. Next, the AP may send the first IP address, where the first IP address is the IP address assigned by the AP to the electronic device. When the electronic device receives the preset Beacon frame from the AP, it can start monitoring the preset port, and the preset port is used to receive the first IP address. The preset port can be pre-configured in the electronic device, or the preset port can be an AP directed to electronic equipment. After that, the electronic device may receive the first IP address from the AP from the preset port.

Based on the above technical solution, after the AP can broadcast the preset Beacon frame carrying the indication information to indicate that the AP can actively send the first IP address, the electronic device can receive the first IP address from the AP. Compared with the conventional technology, the electronic device obtains the IP address through four stages of DHCP, and the embodiment of the present application simplifies the process of obtaining the IP address by the electronic device. In this way, the speed at which the electronic device obtains the IP address can be improved, thereby reducing the time it takes for the electronic device to connect to the WiFi, and improving the user experience.

With reference to the first aspect, in another possible design manner, the AP may periodically send an action frame to the electronic device, where the action frame includes the first IP address. After that, the electronic device can receive the Action frame from the AP from the preset port.

It can be understood that, the AP periodically sends the Action frame, which can improve the success rate of the AP sending the first IP address. In this way, the time for the electronic device to obtain the first IP address can be reduced, and the speed of the electronic device to obtain the first IP address is improved.

With reference to the first aspect, in a possible design manner, the AP may periodically broadcast the first message, where the first message includes the first IP address.

With reference to the first aspect, in another possible design manner, the AP includes multiple queues, and each queue in the multiple queues has a different priority, and the priority is used to indicate the order in which the AP processes different queues in the multiple queues. The processing queue is for the AP to send data in the queue. That is to say, the AP can send the data in the queue with the higher priority in preference to the data in the queue with the lower priority.

The AP may add the first IP address to the queue with the highest priority among the multiple queues.

It can be understood that adding the first IP address to the high priority queue by the AP can improve the ability of the first IP address to preempt the air interface, reduce the time for the AP to wait for sending the first IP address, and thereby improve the speed at which the electronic device obtains the first IP address.

The AP may receive the first response message from the electronic device.

In this way, after the AP receives the first response message, it can determine that the electronic device has received the first IP address.

With reference to the first aspect, in another possible design manner, after the electronic device receives the first IP address from the AP from the preset port, the electronic device may stop monitoring the preset port.

It can be understood that, after the electronic device has received the first IP address, it can stop the preset port and continue to monitor. In this way, the power consumption of the electronic device can be reduced.

In combination with the first aspect, in another possible design manner, the indication information includes a first value or a second value, the first value is used to indicate that the AP has the ability to actively send the IP address assigned by the AP to the electronic device, and the second value is It is used to indicate that the AP does not have the ability to actively send the IP address assigned by the AP to the electronic device. After the AP broadcasts the preset Beacon frame, the electronic device determines, according to the indication information, whether the AP has the ability to actively send the IP address allocated by the AP to the electronic device. If the indication information includes the first value, the AP periodically broadcasts the first message.

With reference to the first aspect, in another possible design manner, if the indication information includes the second value, the electronic device sends a DHCP DISCOVER message to the AP.

That is, if the indication information includes the second value, it means that the AP does not have the ability to actively send the IP address allocated by the AP to the electronic device. Therefore, the electronic device can send a DHCP DISCOVER message to the AP, and obtain the IP address allocated by the AP based on the Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol, DHCP).

After that, the electronic device may receive the first IP address from the AP from the preset port. Then, the electronic device may send a first response message to the AP, where the first response message is used to indicate that the electronic device has received the first IP address.

Based on the above solution, after the AP can broadcast the preset Beacon frame carrying the indication information to indicate that the AP can actively send the first IP address, the electronic device can receive the first IP address from the AP. Compared with the conventional technology, the electronic device obtains the IP address through four stages of DHCP, and the embodiment of the present application simplifies the process of obtaining the IP address by the electronic device. In this way, the speed at which the electronic device obtains the IP address can be improved, thereby reducing the time it takes for the electronic device to connect to the WiFi, and improving the user experience.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

For example, a process, method, system, product or device comprising a series of steps or modules is not limited to the listed steps or modules, but may optionally also include other unlisted steps or modules, or optionally also Other steps or modules inherent to these processes, methods, products or devices are included.

In addition, in the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations or illustrations. Any embodiment or design described in this application as "exemplary" or "such as" should not be construed as preferred or advantageous over other embodiments or designs. Rather, use of words such as "exemplary" or "such as" is intended to present concepts in a specific manner.

With the development of science and technology, more and more electronic devices (such as mobile phones, notebook computers, etc.) perform wireless communication through wireless fidelity (Wireless Fidelity, WIFI) technology. In the process of connecting an electronic device to WiFi, the electronic device needs to obtain an IP address and perform network connection through the IP address.

In the conventional technology, before the electronic device obtains the IP address, the electronic device needs to establish a connection with the AP. Exemplarily, as shown in FIG. 1A , the electronic device may perform a scanning (Scanning, Scan) process, that is, search for WiFi hotspots that are close to the electronic device. In addition, the AP can broadcast a beacon Beacon frame, and the Beacon frame includes: the AP's Extended Service Set Identifier (ESSID), the AP's BSSID (that is, the MAC address), and the encryption method (for example, no password, Wired Equivalent Privacy Protocol) (Wired Equivalent Privacy, WEP) WEP encryption, Wi-Fi network security access (Wi-Fi Protected Access, WPA) or WPA2 encryption), transmission rate, etc. Afterwards, the AP and the electronic device may perform an authentication (Authentication, Auth) process (for example, a process in which the user enters a password and the AP performs authentication). Next, the AP and the electronic device may perform an association (Association, Assoc) process. For example, the Assoc process may be: the electronic device may send an association request frame to the AP; then, the AP may add parameter information of the electronic device to the database, and send an association response to the electronic device. Then, the AP and the electronic device can perform a four-way handshake process to establish a connection.

After that, the electronic device can obtain the IP address through the four stages of the Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol, DHCP). Among them, the four stages of the DHCP include: discovery stage, offer stage, selection stage and confirmation stage. Exemplarily, as shown in FIG. 1B , an electronic device (such as a mobile phone) may broadcast a DHCPDISCOVER message to request to obtain an IP address. The DHCP DISCOVER message includes: the IP address of the mobile phone, the IP address of the AP, and the MAC address of the mobile phone. The IP address of the mobile phone is 0.0.0.0, and the IP address of the AP is 255.255.255.255. After that, at least one AP that receives the DHCP DISCOVER message and can provide an IP address will send a DHCP OFFER message to the mobile phone. The DHCP OFFER message includes information such as the IP address of the AP, the IP address of the mobile phone, the subnet mask, and the IP address provided for the mobile phone. Then, the mobile phone can receive at least one DHCP DISCOVER message, select an IP address from multiple DHCPOFFER messages (usually select the IP address carried in the first received DHCP OFFER message), and broadcast a DHCP REQUEST message , to indicate that the mobile phone has obtained an IP address, and the DHCP REQUEST message carries the IP address obtained by the mobile phone and the IP address of the AP that provides the IP address. Then, the AP that provides the IP address can send a DHCP ACK message to the mobile phone to confirm the IP address.

It should be noted that, for a specific manner in which an electronic device obtains an IP address through DHCP, reference may be made to an open source protocol (eg, DHCP Server ver: 4.2.5), which will not be repeated here.

However, in the above-mentioned conventional technology, the electronic device needs to go through the above-mentioned four stages (discovery stage, provision stage, selection stage and confirmation stage) before it can obtain the IP address. Not only is the process more cumbersome, but also the speed of obtaining an IP address is low.

To this end, an embodiment of the present application provides a method for obtaining an IP address, and the method is applied in a process of obtaining an IP address by an electronic device. In this method, the electronic device can receive an IP address from the AP, where the IP address is an address assigned by the AP to the electronic device. Afterwards, the electronic device may send a response message to indicate that the electronic device has received the IP address. That is to say, only two interactions are required between the electronic device and the AP, and the electronic device can obtain the IP address. Therefore, the method provided by the present application can simplify the interaction process between the electronic device and the AP, and improve the speed at which the electronic device obtains the IP address.

Exemplarily, as shown in FIG. 2B , the communication system includes a plurality of electronic devices (such as a mobile phone 201 and a mobile phone 203 ) and an AP 202 . The distance between the mobile phone 203 and the AP 202 is smaller than the preset distance threshold.

The AP 202 can send a preset Beacon frame carrying the indication information, and the mobile phone 201 can identify the indication information sent by the AP 202. As shown in FIG. 3 , the method for obtaining the IP address may include: S301-S307.

S301 and AP202 broadcast the preset Beacon frame.

The preset Beacon frame includes indication information, and the indication information is used to indicate that the AP 202 has the ability to actively send the IP address allocated by the AP 202 to the mobile phone 201 . Exemplarily, if the field name of the above-mentioned indication information is "FASTIE", the value of the above-mentioned indication information is 1 (for example, as shown in FIG. 4 ).

In this embodiment of the present application, the AP 202 may periodically broadcast the preset Beacon frame. Exemplarily, the AP 202 may broadcast a preset Beacon frame every preset duration a. For example, the above-mentioned preset duration a may be 0.01 second, 0.1 second, or 1 second, and the embodiment of the present application does not limit the preset duration a.

In this embodiment of the present application, before the AP202 broadcasts the preset Beacon frame, the mobile phone 201 may establish a connection with the AP202. Wherein, after the mobile phone 201 establishes a connection with the AP 202 , the AP 202 can assign an IP address to the mobile phone 201 .

It should be noted that, for the process of establishing the connection between the mobile phone 201 and the AP 202 , reference may be made to the above description of FIG. 1A , which will not be repeated here.

S302, the mobile phone 201 receives the preset Beacon frame from the AP202.

In this embodiment of the present application, the mobile phone 201 can identify the indication information in the preset Beacon frame. That is to say, the mobile phone 201 can parse the preset Beacon frame to determine whether the AP 202 has the ability to actively send the IP address allocated by the AP 202 to the mobile phone 201.

In some embodiments, if there is indication information in the preset Beacon frame, the mobile phone 201 can determine that the AP 202 can actively send the first IP address, and the mobile phone 201 can execute S303.

In other embodiments, after the mobile phone 201 receives the preset Beacon frame from the AP 202 , the mobile phone 201 determines whether the AP 202 has the ability to actively send the IP address allocated by the AP 202 to the mobile phone 201 according to the indication information. Wherein, the indication information includes the first numerical value or the second numerical value. The first value and the second value may be any two different values. For example, the first value may be 1 and the second value may be 0.

In a possible design, when the indication information includes the first value, the mobile phone 201 can determine that the AP 202 has the ability to actively send the IP address allocated by the AP 202 to the mobile phone 201, and the mobile phone 201 can execute S303. When the indication information includes the second value, the mobile phone 201 can determine that the AP 202 does not have the ability to actively send the IP address allocated by the AP 202 to the mobile phone 201, and the mobile phone 201 can send a DHCP DISCOVER message to the AP 202. That is, the mobile phone 201 can obtain the first IP address based on DHCP. Specifically, for the description that the mobile phone 201 obtains the first IP address through the four stages of DHCP in the conventional technology (ie, the discovery stage, the offer stage, the selection stage, and the confirmation stage), reference may be made to the description of FIG. To repeat.

It should be noted that, after the mobile phone 201 receives the preset Beacon frame from the AP 202, the mobile phone 201 and the AP 202 can perform the Auth process, the Assoc process and the four-way handshake process. For the specific description of the Auth process, the Assoc process, and the four-way handshake process, you can refer to the introduction to FIG. 1A in the above-mentioned embodiment, and the introduction to the Auth process, the Assoc process, and the four-way handshake process in the conventional technology, which will not be repeated here. .

It should be noted that, because the AP 202 can actively send the first IP address. In this embodiment of the present application, after the mobile phone 201 performs the Auth process, the Assoc process, and the four-way handshake process, the mobile phone 201 does not need to send a DHCP DISCOVER message.

S303, the mobile phone 201 starts the preset port monitoring.

Wherein, the preset port is used to receive the first IP address from AP202.

It should be noted that, the embodiment of the present application does not limit the preset ports in the mobile phone 201 . That is, any port in the mobile phone 201 may be a preset port to obtain the first IP address.

In some embodiments, the preset port may be specified by AP 202 . Specifically, the above-mentioned Beacon frame may further include a port number, where the port number is used to identify a preset port. Exemplarily, if the above-mentioned preset Beacon frame includes a port number, the field name of the port number is "Fast Port", and the value of the port number is "8899" (for example, as shown in FIG. 5A ), then the preset port can be an electronic port. Port 8899 in the device. Optionally, the above-mentioned preset Beacon frame may include multiple port numbers, and each port number corresponds to a preset port. For example, if the field name of the port number is "Fast Port" and the value of the port number is "8899, 25, 68" (for example, as shown in FIG. 5B ), the default ports can be port 8899, port 25 and port 25 in the electronic device. port 68.

After the mobile phone 201 receives the preset Beacon frame from the AP 202, the mobile phone 201 can obtain the port number. Next, the mobile phone 201 can determine the preset port corresponding to the port number, and start the preset port to monitor, so as to obtain the first IP address. For example, if the mobile phone 201 receives the preset Beacon frame as shown in FIG. 5A , that is, the port number is “8899”, and the port whose port number is “8899” is port a. The mobile phone 201 can start the port a for monitoring. That is, the mobile phone 201 can obtain the first IP address through the port a. For another example, if the mobile phone 201 receives the preset Beacon frame as shown in FIG. 5B , that is, the value of the port number is "8899, 25, 68", and it is assumed that the port with the value of the port number "8899" is port a, the port The port whose value is "25" is port b, and the port whose port number is "68" is port c. The mobile phone 201 can start the port a, the port b and the port c to monitor at the same time. That is, the mobile phone 201 can obtain the first IP address allocated by the AP 202 through any one of the port a, the port b, and the port c.

In other embodiments, the preset port may be designated by the mobile phone 201 . Exemplarily, when the mobile phone 201 is shipped from the factory, the staff may configure at least one port in the mobile phone 201 as a preset port to obtain the first IP address. For example, the preset port may be port a in the mobile phone 201 . For another example, the preset ports may be port a, port b, and port c in the mobile phone 201 .

In this embodiment of the present application, the mobile phone 201 may start listening on a preset port at the following timing a, timing b, timing c, or timing d to obtain the first IP address.

At timing a, the mobile phone 201 may start monitoring the preset port after receiving the preset Beacon frame from the AP 202 . For example, after receiving the preset Beacon frame shown in FIG. 5A , the mobile phone 201 can start monitoring on port a.

At timing b, the mobile phone 201 can start listening on the preset port during the Auth process between the mobile phone 201 and the AP 202 . Alternatively, the mobile phone 201 may start listening on a preset port after the mobile phone 201 and the AP 202 complete Auth.

At timing c, the mobile phone 201 can start listening on the preset port during the Assoc process between the mobile phone 201 and the AP 202 . Alternatively, the mobile phone 201 may start listening on a preset port after the mobile phone 201 and the AP 202 complete the Assoc.

At timing d, the mobile phone 201 may start the preset port monitoring during the four-way handshake between the mobile phone 201 and the AP 202 . Alternatively, the mobile phone 201 may start the preset port monitoring after the mobile phone 201 and the AP 202 complete the four-way handshake. In the following embodiments, the mobile phone 201 starts the preset port monitoring at timing a, that is, the mobile phone 201 starts the preset port monitoring after receiving the preset Beacon frame from the AP 202 as an example to introduce the method of the embodiment of the present application.

S304. The AP 202 sends the first IP address.

The first IP address is the first IP address allocated by the AP 202 to the mobile phone 201 .

In this embodiment of the present application, the AP 202 may send the first IP address in the following manner.

Manner 1, the AP 202 may send an action frame to the mobile phone 201, where the Action frame includes the first IP address. Optionally, the Action frame further includes information such as the IP address and subnet mask of the AP202. Exemplarily, if the field name of the first IP address is "Fast IP", the value of the first IP address is "192.168.1.1" (for example, as shown in FIG. 6 ).

In a second manner, the AP 202 may broadcast the first IP address through a User Datagram Protocol (User Datagram Protocol, UDP).

In a third way, the AP 202 may broadcast the message carrying the first IP address through UDP. Specifically, the AP 202 may broadcast the first message via UDP, where the first message includes the first IP address. Optionally, the first message further includes information such as the IP address and subnet mask of the AP 202. In the following embodiments, the method of the embodiment of the present application is described by taking the AP 202 broadcasting the first IP address through UDP as an example.

It can be understood that the AP 202 can send the first IP address to the mobile phone 201 without receiving the indication message (DHCP DISCOVER message) sent by the mobile phone 201 . In this way, the time spent by the AP 202 waiting to receive the DHCP DISCOVER message during the process of acquiring the first IP address by the mobile phone 201 can be reduced, and the speed of acquiring the first IP address by the mobile phone 201 is improved.

It should be noted that, when the AP 202 prepares to send the first IP address, it may also need to send other messages. In this way, the AP 202 may send the first IP address after sending other messages, which prolongs the time for the AP 202 to send the first IP address.

In some embodiments, in order to reduce the time for the AP 202 to wait for sending the first IP address, the AP 202 can increase the priority of sending the first IP address, so that the AP 202 can send the first IP address preferentially. Specifically, the AP 202 includes multiple queues, and each of the multiple queues has a different priority, and the priority is used to indicate the order in which the AP 202 processes different queues among the multiple queues. The AP202 processing queue is the data in the AP202 sending queue. That is to say, when the priority of the queue is higher, the AP 202 can preferentially send the data in the queue.

Before the AP 202 sends the first IP address, the AP 202 may add the first IP address to the first queue, where the first queue is the queue with the highest priority among the multiple queues. After that, the AP 202 can send the data in the queue according to the order of queue priority from high to low.

It should be noted that the AP 202 may also add the first message or the Action frame (that is, the first and third modes above) to the first queue, which is not limited in this embodiment of the present application.

It can be understood that, adding the first IP address to the WiFi high-priority queue by the AP 202 can improve the ability of the first IP address to preempt the air interface, reduce the time that the AP 202 waits for sending the first IP address, and further improve the speed at which the mobile phone 201 obtains the first IP address. .

Of course, when the AP 202 sends the first IP address, the sending may fail. In this way, even if the AP 202 sends the first IP address, the mobile phone 201 cannot obtain the first IP address.

In some embodiments, in order to ensure that the AP 202 can successfully send the first IP address, the AP 202 may periodically send the first IP address. Specifically, the AP 202 may send the first IP address every first preset time period. The first preset duration is not limited in this embodiment of the present application. For example, the first preset duration may be 0.05 seconds. For another example, the first preset duration may be 0.1 seconds.

It should be noted that the AP 202 may also periodically send the first message and the Action frame (ie, the first and third modes above), which is not limited in this embodiment of the present application.

It can be understood that, by sending the first IP address multiple times by the AP 202, the success rate of sending the first IP address by the AP 202 can be improved. In this way, the time for the mobile phone 201 to obtain the first IP address can be reduced, and the speed of the mobile phone 201 to obtain the first IP address is improved.

S305. The mobile phone 201 receives the first IP address.

In some embodiments, when the AP 202 sends an Action frame to the mobile phone 201 (ie, the first method above), the mobile phone 201 can receive the Action frame through a preset port to obtain the first IP address. When the AP 202 broadcasts the first IP address through UDP (that is, the above-mentioned method 2), the mobile phone 201 can receive the first IP address through the preset port. When the AP 202 broadcasts a message carrying the first IP address through UDP (that is, the above-mentioned third mode), the mobile phone 201 can receive the first message through a preset port to obtain the first IP address.

S306, the mobile phone 201 sends a first response message.

The first response message is used to indicate that the mobile phone 201 has received the first IP address.

In some embodiments, if the AP 202 sends the first IP address in mode 1, that is, the AP 202 sends an Action frame to the mobile phone 201, after the mobile phone 201 receives the Action frame, the mobile phone 201 can send an Action confirmation message to the AP.

In other embodiments, if the AP 202 sends the first IP address in the second way (or the third way), that is, the AP 202 broadcasts the first IP address through UDP, after the mobile phone 201 receives the first IP address, the mobile phone 201 can pass UDP broadcast acknowledgment character (Acknowledge character, ACK).

In some embodiments, after the mobile phone 201 sends the first response message, the mobile phone 201 can stop monitoring the preset port.

It can be understood that, after the mobile phone 201 obtains the first IP address, the mobile phone 201 does not need to obtain the IP address. Therefore, the mobile phone 201 can stop monitoring the preset port to reduce the power consumption of the mobile phone 201 .

S307. The AP 202 receives the first response message.

In some embodiments, if the AP 202 is periodically sending the first IP address, after the AP 202 receives the first response message, the AP 202 may stop sending the first IP address.

Based on the above technical solution, the AP 202 may broadcast a preset Beacon frame carrying the indication information to indicate that the AP 202 can actively send the first IP address. After that, the mobile phone 201 can start listening on the preset port. After the WIFi link layer is established (ie, the Auth process, the Assoc process, and the four-way handshake process shown in FIG. 1A ), the AP 202 can send the first IP address. After the mobile phone 201 receives the first IP address, a first response message may be sent to the AP 202 to indicate that the mobile phone 201 has received the first IP address. In this way, compared with the conventional technology in which the mobile phone 201 obtains the IP address through four stages of DHCP, the embodiment of the present application simplifies the process for the mobile phone 201 to obtain the IP address. In this way, the speed at which the mobile phone 201 obtains the IP address can be improved, thereby reducing the time it takes for the mobile phone 201 to connect to the WiFi, and improving the user experience.

In other embodiments, if the AP 202 cannot broadcast the preset Beacon frame carrying the indication information, that is, the Beacon frame sent by the AP 202 is a conventional beacon frame, the mobile phone 201 confirms that the Beacon frame does not carry the Beacon frame after receiving the Beacon frame. The above indication information, that is, the AP 202 cannot actively send the first IP address. After that, the mobile phone 201 can obtain the first IP address through the four stages of DHCP in the conventional technology. Specifically, for the description that the mobile phone 201 obtains the first IP address through the four stages of DHCP in the conventional technology (namely, the discovery stage, the provision stage, the selection stage, and the confirmation stage), reference may be made to the description of FIG. 1B in the above-mentioned embodiment. To repeat.

In other embodiments, the AP can interact with multiple electronic devices, the AP can broadcast a preset Beacon frame carrying the indication information, and the multiple electronic devices include: an electronic device that can recognize the indication information and an electronic device that cannot recognize the indication information. Electronic equipment.

2B is taken as an example, that is, multiple electronic devices include mobile phone 201 and mobile phone 203, and AP is AP 202 as an example, to introduce a method for obtaining an IP address provided by an embodiment of the present application. The mobile phone 201 is an electronic device that can recognize the indication information, the mobile phone 203 is an electronic device that cannot recognize the indication information, and the AP 202 is an AP that can broadcast the above-mentioned preset Beacon frame. As shown in FIG. 7 , after S301, the method for obtaining the IP address may include: S701-S705.

It should be noted that, for the manner in which the mobile phone 201 obtains the IP address, reference may be made to the methods in the foregoing S301-S307, which will not be repeated here.

S701, the mobile phone 203 receives the preset Beacon frame from the AP202.

In this embodiment of the present application, the mobile phone 203 cannot identify the indication information in the preset Beacon frame. That is, the mobile phone 203 cannot determine whether the AP 202 can actively send the first IP address. Also, the mobile phone 203 cannot start listening on the default port.

In a possible design, if the mobile phone 203 cannot recognize the indication information in the preset Beacon frame, the mobile phone 203 executes S702.

It should be noted that, after the mobile phone 201 receives the preset Beacon frame from the AP 202, the mobile phone 201 and the AP 202 can perform the Auth process, the Assoc process and the four-way handshake process. For the specific description of the Auth process, the Assoc process, and the four-way handshake process, you can refer to the introduction to FIG. 1A in the above-mentioned embodiment, and the introduction to the Auth process, the Assoc process, and the four-way handshake process in the conventional technology, which will not be repeated here. .

S702, the mobile phone 203 broadcasts a DHCP DISCOVER message.

Wherein, the DHCP DISCOVER message is used to request to obtain the first IP address.

S703 , the AP 202 sends a DHCP OFFER message to the mobile phone 203 .

The DHCP OFFER message includes information such as the IP address, target IP address, first IP address, and subnet mask of the AP.

S704, the mobile phone 203 broadcasts a DHCP REQUEST message.

The DHCP REQUEST message is used to indicate that the mobile phone 203 has obtained the first IP address.

S705 , the AP 202 sends a DHCP ACK message to the mobile phone 203 .

The DHCP ACK message is used to confirm the first IP address.

It should be noted that, for the specific introduction of the four stages of DHCP in the above S702-S704, reference may be made to the method for obtaining an IP address by an electronic device through DHCP in the conventional technology, which will not be repeated here.

Based on the above technical solution, if the mobile phone 201 can identify the preset Beacon frame, the mobile phone 201 does not need to send a DHCPDISCOVER message. The mobile phone 201 can receive the first IP address actively sent by the AP 202. If the mobile phone 203 cannot recognize the preset Beacon frame, the mobile phone 203 sends a DHCP DISCOVER message to obtain the first IP address. In this way, any electronic device (an electronic device that can recognize the preset Beacon frame and an electronic device that cannot recognize the preset Beacon frame) can obtain the IP address from the AP 202 .
