detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

In the prior art, when the STA device communicates with the AP device, at least the 48-bit basic service of the AP device needs to be filled in the Receiver Address (RA) field or the Transmitter Address (TA) field in the MAC frame header. A Basic Service Set Identifier (BSSID) to indicate to which AP the data frame is sent or which AP to send. The BSSID in the prior art is the MAC address of the AP device. Therefore, in the embodiments of the present invention, the MAC address of the AP device is taken as an example for description. In the prior art, the MAC frame header in the data frame is long, occupying most of the space of the data frame, thereby causing less data amount to be carried by the data frame, lower utilization rate, and utilization of the channel for transmitting the data frame. The problem of the lower rate is provided by the embodiment of the present invention. By defining an Access Point Identifier (APID) for the AP device, the MAC frame header of the data frame in the communication process between the STA device and the AP device is used to identify the AP device. The MAC address of the bit is replaced with the short identifier of the AP device to further reduce the length of the MAC frame header, and the technical solution for improving the utilization of the channel of the transmitted data frame by reducing the length of the MAC frame header. The technical solution of the present invention mainly includes how to communicate through the short identifier of the AP device.

FIG. 1 is a flowchart of a communication method according to an embodiment of the present invention. As shown in FIG. 1, the method in this embodiment includes:

Step 101: Receive a short identifier notification message sent by the AP device, where the short identifier notification message includes The short identifier of the AP device is shorter than the length of the MAC address of the AP device, and the short identifier of the AP device is used to uniquely identify the AP device in the area where the AP device is located.

The area where the AP device is located mainly refers to a certain range centered on the AP device. The area where each AP device is located can be set when the AP device is deployed. For example, if the coverage of the AP device is half a kilometer, the area where the AP device is located can be set to an area with a radius of 5 kilometers.

Step 102: Generate a communication message, where the receiving address of the communication message is a short identifier of the AP device. Step 103: Send a communication message to the AP device.

In this embodiment, the communication message may be a MAC frame.

In this embodiment, another device that communicates with the AP device generates a communication message, and uses the short identifier of the AP device as the receiving address of the communication message, and then sends the communication message to the AP device to implement communication with the AP device. The length of the short identifier of the AP device is smaller than the length of the MAC address of the AP device (ie, the BSSID). Therefore, the MAC frame header of the communication message in this embodiment is smaller than the MAC frame header of the prior art, and the valid data in the communication message is added. The proportion increases the utilization of communication message frames, which in turn increases the utilization of the channel (called the transmission channel) for transmitting communication messages.

The other device that communicates with the AP device may be a STA device or another

AP equipment. This embodiment does not limit this.

During the communication between the AP device and the AP device, one of the AP devices generates a communication message frame, and the communication message frame is sent to another AP device. The receiving address of the communication message generated by one of the AP devices is a short identifier of the another AP device, and the sending address is a short identifier of the one of the AP devices. The length of the short identifier of the AP device is smaller than the length of the MAC address of the AP device. Therefore, the MAC frame header of the data frame in this embodiment is smaller than the MAC frame header of the prior art, and the effective data portion in the communication message is increased, and the communication is improved. The utilization of the message, in turn, improves the utilization of the channel through which the communication message is transmitted. During the communication between the STA device and the AP device, the STA device generates a communication message, which is an uplink MAC frame. The receiving address of the uplink MAC frame generated by the STA device is a short identifier of the AP device, and the sending address is an Association Identifier (AID) of the STA. The length of the short identifier of the AP device is smaller than the length of the MAC address of the AP device. Therefore, the MAC frame header of the uplink MAC frame in this embodiment is smaller than the MAC frame header of the prior art, and the effective data portion in the uplink MAC frame is increased. The utilization of the uplink MAC frame further improves the utilization of the channel for transmitting the uplink MAC frame.

Whether the other device communicating with the AP device is the STA device or the AP device has known the short identifier of the AP device before generating the MAC frame.

Optionally, the short identifier of the AP device is automatically generated by the AP device according to the location information of the AP device, so that the generated short identifier uniquely identifies the AP device in the area where the AP device is located. Because the locations of different APs are different, the short identifiers generated based on the location information are unique, so that different APs use the same short identifiers.

Optionally, the short identifier of the AP device is uniformly allocated by the first configuration server according to the type of the AP device to access the network, so that the allocated short identifier uniquely identifies the AP device in the area where the AP device is located. The first configuration server is a regional network management function entity, and is responsible for unified management of AP devices in the entire area. The regional network management function entity pre-stores a defined short identifier. The area network management function entity allocates a short identifier to the AP device according to the type of the AP device accessing the network. The type of the access network includes the identification information of the area where the network is located, the identification information of the network operation organization, and the service type information (such as sensing detection, intelligent measurement, etc.) for the network. The area network management function entity uniformly allocates short identifiers to the AP devices, and also ensures that different APs use different short identifiers, that is, the uniqueness of the short identifiers is ensured.

Optionally, the short identifier of the AP device may include a network identifier and an intra-network identifier. Among them, the network identifier The second configuration server is uniformly allocated according to the type of the access device of the AP device, and the identifier of the network is uniformly generated and allocated by the third configuration server or automatically generated by the AP device according to the location information of the AP device, where the second configuration server and the first configuration are configured. Similar to the server, the server is also a regional network management function entity. It is responsible for unifying the APs of different networks in the entire area. The network management function entity is mainly to allocate network identifiers for APs of different networks to ensure access to different network types. APs have different network identifiers. The third configuration server may be an AP management function entity in the local area network, and is mainly responsible for uniformly generating and distributing the intranet identifiers for each AP device in a local area network. Since the AP management function entity uniformly generates and allocates the intra-network identifiers for the AP devices, it can be ensured that the intra-network identifiers generated by different AP devices cannot conflict, and new conflicts are required if the conflicts are required. For intra-network identification, the AP device can also automatically generate information based on its own location information. Since the locations of different AP devices are different, the identifiers generated in the network according to the location information are also different. The method ensures that the short identifier of the AP device can uniquely identify the AP device in the area where the AP device is located by using the network identifier and the identifier in the network.

Preferably, the short identifier of the AP device may be 16 bits in length.

Further, preferably, the short identifier of the AP device may include a 6-bit network identifier and a 10-bit network identifier.

Optionally, the STA device can obtain the short identifier of the AP device in the process of associating with the AP device. For example, the AP device carries its own short identifier in the association response sent to the STA, so that the STA device obtains the short identifier of the AP device from the association response.

Optionally, the STA device may also obtain the short identifier of the AP device in the process of discovering the AP device. For example, the AP device may carry its own short identifier in the broadcast beacon frame, so that the STA device acquires the short identifier of the AP device from the new standard frame. For another example, the AP device may carry its own short identifier in the probe response frame sent to the STA device, so that the STA device obtains the short identifier of the AP device from the probe response frame. 2A is a flowchart of a data frame sending method according to an embodiment of the present invention. As shown in FIG. 2A, the method in this embodiment includes:

Step 201: The STA device sends an association request to the AP device.

In this embodiment, after the STA device discovers the AP device and passes the authentication, it sends an association request to the AP device to request association with the AP device. Correspondingly, the AP device receives the association request sent by the STA device.

Step 202: The STA device receives an association response sent by the AP device to associate with the AP device, where the association response includes a short identifier of the AP device.

In this embodiment, the length of the short identifier of the AP device is smaller than the length of the MAC address of the AP device, and is used to uniquely identify the AP device in the area where the AP device is located.

After receiving the association request of the STA device, the AP device identifies that the STA device is to be associated with itself. The AP device allocates an association identifier (AID) for the STA device to identify different STA devices associated with the AP device in the service area. In this embodiment, the AP device encapsulates the short identifier of the AP device and the AID assigned to the STA device in the association response, and then sends the association response to the STA device.

The STA device receives the association response sent by the AP device, and obtains the AID allocated by the AP device and the short identifier of the AP device from the association response.

In this embodiment, the short identifier notification message is an association response. Step 201 and step 202 can be regarded as a specific implementation manner in which the UE receives the short identifier notification message.

The short identifier of the AP device may be automatically generated by the AP device according to the location information of the AP device, or may be uniformly allocated by the first configuration server to the AP device according to the type of the AP device accessing the network.

The short identifier of the AP device may include the network identifier and the identifier in the network, or may not distinguish the network. Identification and intranet identification.

Preferably, the short identifier of the AP device may be 16 bits in length. Further, if the short identifier of the AP device includes the network identifier and the intra-network identifier, the network identifier can occupy 6 bits, and the intra-network identifier occupies 10 bits.

Step 203: The STA device generates an uplink MAC frame, where the receiving address of the uplink MAC frame is

The short identifier of the AP device, and the sending address is the AID of the STA device.

After the STA device is associated with the AP device, the STA device generates an uplink MAC frame when it needs to send an uplink MAC frame to the AP device. The structure of the uplink MAC frame is as shown in FIG. 2B, and mainly includes: a frame control (FC) domain, a duration domain (Distence domain), an address-domain (Addressl), an address two domain (Address2), and an address three domain. ( Address3 ) , Sequence Control Domain ( Sequence Control Domain ) , Address Four Domain ( Address 4 ) , Quality of Service Control Domain ( QoS Control Domain ) , Frame Body Domain ( Frame Body Domain ) and Frame Check Sequence ( FCS ) area. The address one field is used to fill the receiving address, and the address two field is used to fill the sending address. For the three fields of the address and the address, the four domains can be referred to the prior art, which is not described in the embodiment of the present invention.

In this embodiment, the STA device uses the short identifier of the AP device and the AID of the STA device as the receiving address and the sending address of the uplink MAC frame, respectively. That is, the address in the address field is filled with the short identifier of the AP device, and the address in the second domain is filled with the AID of the STA device. The structure of the uplink MAC frame after adding the address one domain and the address two domain is as shown in Fig. 2C.

In the prior art, in the MAC frame header of the uplink MAC frame sent by the STA device to the AP device, the address in the address field is filled with the MAC address of the AP device, and the length of the MAC address of the AP device is 48 bits.

It can be seen that, by using the short identifier of the AP device in this embodiment, the MAC frame header of the uplink MAC frame is reduced, the proportion of the effective data portion in the uplink MAC frame is improved, and the uplink MAC is improved. The utilization of the frame, in turn, helps to improve the utilization of the transmission channel.

The length of the AID of the STA device is 16 bits. Therefore, the STA device uses the AID instead of the 48-bit MAC address of the STA device, which is also beneficial for reducing the MAC frame header of the uplink MAC frame.

Step 204: The STA device sends an uplink MAC frame to the AP device.

The STA device then transmits the uplink MAC frame to the AP device. Correspondingly, the AP device receives the uplink MAC frame sent by the STA device. For the AP device, the received address of the uplink MAC frame is compared with its own short identifier; if the comparison result is the same, indicating that it is the receiver of the uplink MAC frame, the valid data in the uplink MAC frame is parsed and obtained; If the comparison result is different, indicating that it is not the receiver of the uplink MAC frame, the uplink MAC frame is discarded.

In this embodiment, the STA device obtains the short identifier of the AP device in the process of associating the AP device, and uses the obtained short identifier of the AP device to replace the MAC address of the AP device as the receiving address of the uplink MAC frame to communicate with the AP device. Since the length of the short identifier of the AP device is smaller than the length of the MAC address of the AP device, the MAC frame header in the uplink MAC frame is reduced, the utilization of the uplink MAC frame is improved, and the utilization of the transport channel is improved.

FIG. 3 is a flowchart of a data frame sending method according to another embodiment of the present invention. As shown in FIG. 3, the method in this embodiment includes:

Step 301: The STA device receives a beacon frame broadcast by the AP device, where the beacon frame includes a short identifier of the AP device.

In this embodiment, the AP device periodically broadcasts the beacon frame, so that the STA device can discover the AP device and associate with the AP device.

The AP device carries the BSSID (ie, the MAC address) of the AP device in the beacon frame, so that the STA determines the basic service set (BSS) to be accessed by the STA. In this embodiment, the AP device is simultaneously The beacon frame carries the short identifier of the AP device. That is, the beacon frame of the embodiment includes both The BSSID of the AP device and the short identifier of the AP device.

Correspondingly, the STA device receives the beacon frame broadcasted by the AP device, and obtains the BSSID of the AP device and the short identifier of the AP device from the beacon frame, and obtains the BSSID of the AP device and the short identifier of the AP device at the same time. Correspondence.

In this embodiment, the length of the short identifier of the AP device is smaller than the length of the BSSID of the AP device, and is used to uniquely identify the AP device in the area where the AP device is located.

In this embodiment, the short identity notification message is a beacon frame. Step 301 can be regarded as a specific implementation manner in which the UE receives the short identification notification message.

The short identifier of the AP device may be automatically generated by the AP device according to its own location information, or may be uniformly allocated by the first configuration server according to the type of the AP device accessing the network, so that the generated or allocated short is configured. The identifier can uniquely identify the AP device in the area where the AP device is located.

The short identifier of the AP device may include the network identifier and the identifier in the network, or may not distinguish between the network identifier and the identifier in the network.

Step 302: The STA device and the AP device perform authentication.

After the STA device discovers the AP device, it authenticates with the AP device. This certification process is an existing technology and will not be described in detail here.

Step 303: The STA device sends an association request to the AP device.

After the STA device passes the authentication, the STA device sends an association request to the AP device to associate with the AP device. Correspondingly, the AP device receives the association request of the STA device.

Step 304: The STA device receives an association response sent by the AP device to associate with the AP device. After receiving the association request of the STA device, the AP device allocates an AID for the STA device, and the AP device identifies the different STA devices associated with the STA device in the service area. The AP device encapsulates the allocated AID in the association response and sends it to the STA device.

The STA device receives the association response sent by the AP device, and obtains the AID allocated by the AP device. Step 305: The STA device generates an uplink MAC frame, where the receiving address of the uplink MAC frame is

Step 306: The STA device sends an uplink MAC frame to the AP device.

The foregoing steps 305 and 306 can be referred to the description of step 203 and step 204, and are not described herein again.

In this embodiment, the STA device obtains the short identifier of the AP device in the process of discovering the AP device, and uses the obtained short identifier of the AP device to replace the MAC address of the AP device as the receiving address of the uplink MAC frame to communicate with the AP device. Since the length of the short identifier of the AP device is smaller than the length of the MAC address of the AP device, the MAC frame header in the uplink MAC frame is reduced, the utilization of the uplink MAC frame is improved, and the utilization of the transport channel is improved.

FIG. 4 is a flowchart of a data frame sending method according to another embodiment of the present invention. As shown in FIG. 4, the method in this embodiment includes:

Step 401: The STA device sends a probe request frame to the AP device.

Step 402: The STA device receives a probe response frame sent by the AP device, where the probe response frame includes a short identifier of the AP device.

In this embodiment, the STA device actively broadcasts the probe request frame to enable the surrounding AP device to respond, thereby discovering the AP device. For the AP device, if the probe request frame sent by the STA device is received, the probe response is sent to the STA device to respond, so that the STA device associates with the STA device. The AP device carries the BSSID (ie, MAC address) of the AP device in the probe response frame, so that the STA determines the BSS to be accessed by the STA. In this embodiment, the AP device simultaneously carries the short identifier of the AP device in the probe response frame. That is, the probe response frame of this embodiment includes both the BSSID of the AP device and the short identifier of the AP device.

Correspondingly, the STA device receives the probe response frame sent by the AP device, and obtains the frame from the probe response frame.

The BSSID of the AP device and the short identifier of the AP device, and the corresponding relationship between the BSSID of the AP device and the short identifier of the AP device.

In this embodiment, the short identifier notification message is a probe response frame. Step 401 and step 402 can be regarded as a specific implementation manner in which the UE receives the short identifier notification message.

The short identifier of the AP device may be automatically generated by the AP device, or may be uniformly allocated by the first configuration server according to the type of the AP device accessing the network, so that the short identifier generated or allocated is in the area where the AP device is located. The AP device can be uniquely identified.

Step 403: The STA device and the AP device perform authentication.

Step 404: The STA device sends an association request to the AP device.

Step 405: The STA device receives an association response sent by the AP device to associate with the AP device. Step 406: The STA device generates an uplink MAC frame, where the receiving address of the uplink MAC frame is The short identifier of the AP device, and the sending address is the AID of the STA device.

Step 407: The STA device sends an uplink MAC frame to the AP device.

The foregoing step 403 to step 407 can be referred to the description of step 302 to step 306, and details are not described herein.

In the embodiment shown in FIG. 2A to FIG. 4, the communication message is an uplink MAC frame as an example, but is not limited thereto.

FIG. 5 is a flowchart of a communication method according to another embodiment of the present invention. As shown in FIG. 5, the method in this embodiment includes:

The AP device is uniquely identified in the area where the AP device is located.

Step 502: The AP device receives the communication message.

Step 503: The AP device determines whether the receiving address in the communication message is the same as the short identifier of the AP device. If the determination result is yes, that is, the receiving address in the communication message is the same as the short identifier of the AP device, step 504 is performed; If no, go to step 505.

Step 504: The AP device parses and obtains valid data in the communication message.

Step 505: The AP device discards the communication message.

The communication message in this embodiment may be a MAC frame. In this embodiment, the AP device receives the communication message sent by the other device, and compares the short identifier of the AP device with the receiving address in the communication message to determine whether it is the receiver of the communication message. If the receiving address is the same as the short identifier of the AP device, and the AP device determines that it is the receiver of the communication message, the communication message is parsed to obtain valid data therein. If the receiving address is different from the short identifier of the AP device, and the AP device determines that it is not the recipient of the communication message, the communication message is discarded.

The other device that communicates with the AP device uses the short identifier of the AP device as the receiving address of the communication message. The length of the short identifier of the AP device is smaller than the length of the MAC address of the AP device. Therefore, the MAC frame of the communication message in this embodiment. The header is smaller than the MAC frame header of the prior art, which increases the proportion of valid data in the communication message, improves the utilization of the communication message, and improves the utilization of the transmission channel.

The other device that communicates with the AP device may be an ST A device or another AP device. That is, the communication message received by the AP device may be sent by the STA device, and may be sent by another AP device.

FIG. 6 is a flowchart of a data frame receiving method according to an embodiment of the present invention. As shown in FIG. 6, the method of this embodiment includes:

Step 601: The AP device receives an uplink MAC frame sent by the STA device.

Step 602: The AP device determines whether the receiving address in the uplink MAC frame is the same as the short identifier of the AP device. If the determination result is yes, that is, the receiving address in the uplink MAC frame is the same as the short identifier of the AP device, step 603 is performed; If no, go to step 604.

The short identifier of the AP device is smaller than the length of the MAC address of the AP device. The short identifier of the AP device is used to uniquely identify the AP device in the area where the AP device is located.

Step 603: The AP device parses and obtains valid data in the uplink MAC frame.

Step 604: The AP device discards the uplink MAC frame.

In the embodiment shown in FIG. 6 to FIG. 9, the communication message is an uplink MAC frame as an example, but is not limited thereto.

In the foregoing embodiments, the short identifier of the AP device may include a network identifier and an intra-network identifier. The short identifier of the AP device may also not distinguish between the network identifier and the intra-network identifier. For example, all the bits may be used as the network identifier. The length of the short identifier of the AP device is preferably 16 bits. Based on this, FIG. 10A shows a short identification structure including a 6-bit network identifier and a 10-bit intra-network identifier; FIG. 10B shows a short-identification structure of a 16-bit network identifier, that is, does not include an intra-network identifier.

In the foregoing embodiments, before the AP device receives the MAC frame or the uplink MAC frame, the AP device may be configured with a short identifier that uniquely identifies the AP device in the area where the AP device is located. The operation of configuring the short identifier is an optional operation. A short identifier can be pre-configured on the AP device.

The following describes in detail how to configure short identifiers for AP devices:

For example, a regional management organization uniformly manages the allocation of short identifiers for all APs in the area. A network operation organization that deploys a network (such as a WiFi network) in an area needs to apply for a short identifier available to the regional management organization according to the type and size of the deployed network (such as how many APs need to be deployed), and is in the deployed network. The AP assigns a short identifier obtained by the application to ensure that the short identifiers of the APs deployed in the same area are not duplicated. The area management organization may deploy a regional network management function entity, for example, the first configuration server is responsible for uniformly allocating the short identifiers to the AP devices in the area, and the AP device sends a short identifier acquisition request to the first configuration server, where the short identifier is configured. Get request including AP The type of device access to the network. The type of the access network includes the identification information of the area where the network is located, the identification information of the network operation organization, and the service type information (such as sensing detection, intelligent measurement, etc.) for the network. The AP device receives the short identifier acquisition response sent by the first configuration server, where the short identifier acquisition response includes the short identifier of the AP device. In the method, the short identifier of the AP device is uniformly allocated by the first configuration server from the pre-stored short identifier according to the type of the AP device accessing the network, so that the allocated short identifier is in the area where the AP is located. Uniquely identifies the AP device.

For example, the AP device automatically generates its own short identifier according to its own location, so that the generated short identifier uniquely identifies the AP device in the area where the AP is located. Since the location information of different AP devices is different, the short identifier generated based on the location information can ensure the uniqueness of the entire network.

Further, if the short identifier of the AP device includes the network identifier and the identifier of the network, configuring the short identifier for the AP device includes configuring the network identifier and the identifier of the network for the AP device.

The network identifier can uniquely identify a network in an area, and the area management organization can uniformly manage the allocation of network identifiers of all APs in the area. A method for configuring a network identifier for an AP device may be a regional network management function entity deployed by the area management organization, that is, the second configuration server is uniformly allocated. Specifically, the AP device sends a network identity acquisition request to the second configuration server, where the network identity acquisition request includes a type of the AP device accessing the network. The AP device receives the network identifier acquisition response sent by the second configuration server, where the network identifier acquisition response includes the network identifier in the short identifier of the AP device. In the method, the network identifier in the short identifier of the AP device is uniformly allocated by the second configuration server from the pre-stored network identifier according to the type of the AP device accessing the network, so that the short identifier of the AP device is in the AP device. The AP device can be uniquely identified in the area. In the method, the network identifier is stored on the second configuration server.

The method for configuring the identifier in the network for the AP device may be uniformly generated and allocated by the third configuration server for the AP device. The third configuration server is an AP tube deployed in each local area network. Functional entity. The method specifically includes: the AP device sends an intra-network identity acquisition request to the third configuration server; the AP receives the intra-network identity acquisition response sent by the third configuration server, where the intra-network identity acquisition response includes the short identifier in the AP device. Intranet identification. In the method, the intra-network identifier in the short identifier of the AP device is generated and allocated by the third configuration server according to the intra-network identifier acquisition request, so that the short identifier of the AP device can be uniquely identified in the area where the AP device is located. AP equipment. In the method, if the third configuration server conflicts with the other AP devices generated by the AP device in the embodiment, the third configuration server needs to re-generate the intra-network identifier for the AP device in the embodiment, until The AP devices do not conflict.

The method for configuring the identifier of the network for the AP device may be automatically generated by the AP device according to the location information of the AP. In order to avoid conflicts with the identifiers of other APs in the network, the method specifically includes: the AP device automatically generates an identifier of the first network according to the location information of the AP, and sends an internal identifier request to other APs in the network where the AP device is located. The internal identification request includes a first intra-network identity. Optionally, the AP device can broadcast an internal identification request to the network. If the AP device does not receive the internal identifier response sent by the other AP device after the preset time is over, the AP device uses the identifier of the first network as the identifier of the network in the short identifier of the AP device, so that the short identifier of the AP device is An AP device can be uniquely identified in the area where the AP device is located. After receiving the internal identification request, the other AP devices in the network compare the first intranet identifier with the own intranet identifier; if the comparison result is different, the response is not performed, and the internal The identification request is discarded; if the comparison result is the same, an internal identification response is sent to the AP device that sends the internal identification request. That is, the internal identity response is sent to the AP device when the other AP device has the same identity in the network as the first network.

Optionally, the other AP device may further include, in the internal identifier response, indication information that the identifier in the first network has been used. In this method, if the AP device receives the internal identifier response, it may regenerate a first intra-network identifier, and send another internal identifier request carrying the regenerated first intra-network identifier to other AP devices until it determines that it is The identity of the network is up to now.

The foregoing methods for configuring the short identifiers can solve the problem that the two APs in the adjacent area use the same short identifier, and the STA device in the overlapping coverage area of the two AP devices cannot be identified because the associated AP device cannot be identified. The problem of not being able to communicate properly is conducive to ensuring the quality of communication.

Step 1101: The AP device generates a MAC frame, where the sending address of the MAC frame is a short identifier of the AP device, the length of the short identifier of the AP device is smaller than the length of the MAC address of the AP device, and the short identifier of the AP device is used in the AP. The AP device is uniquely identified in the area where the device is located.

Step 1102: The AP device sends a MAC frame to the receiving device.

In this embodiment, the AP device uses the short identifier of the AP device as the sending address of the MAC frame, and communicates with another device (ie, the receiving device). In the prior art, when the AP device communicates with another device, the sending address used is the MAC address of the AP device, and the length of the MAC address of the AP device is 48 bits, so that the MAC frame header is long, which is used in this embodiment. The short identifier of the AP device is smaller than the MAC address of the AP device, which reduces the MAC frame header, increases the proportion of valid data in the MAC frame, improves the utilization of the MAC frame, and improves the utilization of the transmission channel.

Therefore, the MAC frame header in the downlink MAC frame in this embodiment is smaller than the existing one. The MAC frame header in the technology.

Step 1204: The AP device sends the downlink MAC frame to the STA device.

After the downlink MAC frame is generated, the AP device sends the downlink MAC frame to the STA device. STA set The standby device receives the downlink MAC frame sent by the AP device. Then, the STA device compares the received address in the downlink MAC frame with its own AID to determine whether it is the receiver of the downlink MAC frame. If the judgment result is yes, the STA device parses the downlink MAC frame to obtain valid data therein; if the judgment result is no, the STA device discards the downlink MAC frame.

Further, in order to improve the accuracy of receiving the downlink MAC frame, the STA device may further compare the sending address in the downlink MAC frame with the short identifier of the AP device acquired in the association response, and determine whether the downlink MAC frame is associated with the AP. The device sends to further determine whether it is the receiver of the downlink MAC frame. If the result of the determination is yes, and the AID of the STA is the same as the receiving address in the downlink MAC frame, the STA device parses the downlink MAC frame to obtain valid data therein; if the determination result is no, regardless of the STA's AID and Whether the receiving address in the downlink MAC frame is the same, and the STA device discards the downlink MAC frame.

In this embodiment, the downlink MAC frame sent by the AP device to the STA replaces the BSSID of the AP device in the prior art by using the short identifier of the AP device, reduces the MAC frame header, and increases the proportion of valid data in the downlink MAC frame. The utilization of the downlink MAC frame is improved, thereby improving the utilization of the transmission channel.
