Description

Message processing method, access point equipment and message processing equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to a message processing method, an access point device, and a message processing device.

Background

Wireless Fidelity (WIFI) is a Wireless transmission technology, and is widely used for enterprise access, home network access, and internet of things access due to mobility and convenience of access. The WIFI Access frequency band is divided into a 2.4G frequency band and a 5G frequency band, wherein the 5G frequency band is divided into a high frequency band and a low frequency band, which means that one WIFI device needs to provide support for a full frequency band, and simultaneously supports the 2.4G frequency band, the 5G high frequency band and the 5G low frequency band, and for a chip level of an Access Point (AP) device, three chips need to be deployed, which may increase chip cost; in addition, in some application scenarios of the carry-on WIFI, the main solution is to have the access capability of the WIFI, and because the number of the wireless terminals (STAs, stations) accessing the WIFI is limited, there is no high requirement on the peak rate of the access, but the WIFI needs to have the frequency band coverage capability, and if necessary, the WIFI can provide the 2.4G access capability and the 5G access capability to provide support for different devices.

For these applications and requirements, the prior art proposes a Dual Band Dual Concurrent transmission (DBDC) mode and a Dual Band Adaptive transmission (DBAC) mode. In the DBDC mode, 2.4G and 5G band access respectively use independent chips, and 2.4G and 5G access capabilities can be concurrently provided through different APs.

In the DBAC mode, one chip is adopted for the access of the 2.4G frequency band and the 5G frequency band, and the support of the 2.4G frequency band and the 5G frequency band is provided by switching back and forth between the 2.4G frequency band and the 5G frequency band. The DBAC mode has a drawback in application that when a plurality of AP devices adopting the DBAC mode are disposed in a space, there is a problem of mutual interference, resulting in a great limitation in application of the entire DBAC mode.

In order to solve the problem of mutual interference existing when multiple APs are deployed in the prior art, a channel staggered distribution mode is provided to avoid mutual interference, for example, the channel distribution shown in table 1 can avoid mutual interference collision, and the AP1 and the AP2 occupy different channels, for example, the AP1 occupies channel 1 in the 2.4G frequency band, and the AP2 occupies channel 6 in the 2.4G frequency band.

Table 1 channel profile table

	2.4G frequency band	5G frequency band
			AP1	1	36
AP2	6	52

The scheme of staggered distribution of the channels is mainly limited in that 2.4G frequency bands only have 3 non-mutual interference channels, 5G low-frequency bands only have 2 non-mutual interference channels, 5G high-frequency bands only have 3 non-mutual interference channels, the channels which can be actually used by the AP equipment are limited by national spectrum regulation and the like, and the number of selectable channels is less. Therefore, when multiple APs are deployed, the available channel resources are limited, and the requirement of channel non-conflict cannot be met.

In the system architecture provided in the embodiment of the present application, at least two networks exist, which are respectively represented as a first network and a second network, and the second network and the first network have different network identifiers. Each network includes an AP device and a terminal device, for example, the first network includes: AP device 1, terminal device 1, and terminal device 2, including in the second network: AP device 2, terminal device 3, and terminal device 4, where the network identifier may be represented by a device identifier of the AP device in the network, for example, the network identifier of the first network includes: service Set Identifier (SSID). As another example, the network identification of the first network includes: a Medium Access Control (MAC) address of the AP device is not limited, and in this embodiment, the network identifier may not be limited to the MAC address, and only different networks need to be distinguished. In the embodiment of the present application, each AP device has a broadcast capability, and a message broadcast by the AP device may be sent to a broadcast channel, through which the message is broadcast.

It should be noted that, in some embodiments of the present application, one AP device may be included in one network, as shown in fig. 1, but not limited to, two or more AP devices may also be included in one network, and one master AP device and multiple cascaded AP devices may be provided in one network. Fig. 2 is a schematic structural diagram of a first network according to an embodiment of the present application. Taking an example that two AP devices are included in the first network, where the AP device 1 may serve as a master AP device, the AP device 3 may serve as a tandem AP device, the AP device 3 may provide a communication service for the terminal device 5 and the terminal device 6, and for a message broadcast by the AP device 1, the message may be sent to the terminal device 5 and the terminal device 6 through the AP device 3. In this embodiment of the present application, the number of AP devices set in one network may be determined by combining with a specific scenario, which is not limited herein.

In this embodiment, the AP device 1 may first determine a first frequency band that is not needed to be used by the AP device, then the AP device 1 generates a first message, and finally the AP device 1 may broadcast the first message. Wherein the first message comprises: the network identifier of the first network in which the AP device 1 is located, where the first network is a network formed by the AP device 1 and devices associated with the AP device 1 (Association). The association refers to an association process with the AP device defined in the WIFI standard, for example, after a certain device completes the association process, a link between the device and the AP device is established, and data messages may be mutually received and transmitted. For example, the devices associated with the AP device 1 may be the terminal device 1 and the terminal device 2 shown in fig. 1, and the devices associated with the AP device 1 may also be the AP device 3 and the terminal device 5 and the terminal device 6 shown in fig. 2. In this embodiment, the AP device 1 may instruct, through the first message, the first device to keep silent on the first frequency band, and instruct, through the first message, the second device not to respond to the first message, where the first device is a device in the first network that receives the first message, and for example, the first device may be the terminal device 1 and the terminal device 2 shown in fig. 1. The second device is a device in the second network that receives the first message, for example, the second device may be the terminal device 3 and the terminal device 4 shown in fig. 1.

As for the first frequency band that is not needed to be used, the AP device 1 in the embodiment of the present application may instruct the device in the first network where the AP device 1 is located to keep silent on the first frequency band, so that the first device in the first network may keep silent on the first frequency band after receiving the first message, and thus the device in the first network may not contend for the channel resource corresponding to the first frequency band, and thus there is no interference of the channel resource. In addition, in this embodiment, although the AP device 1 broadcasts the first message, only the device in the first network will respond to the first message, and the device in the second network does not respond to the first message, so that the first message broadcast by the AP device 1 does not affect the use of the first frequency band by the device in the second network.

Next, a message processing method provided in the embodiment of the present application is described from the perspective of the AP device and the first device, and first please refer to fig. 3, which is described from the AP device side, where the message processing method provided in the embodiment of the present application may include the following steps:

301. the AP device determines a first frequency band that the AP device does not need to use.

In this embodiment of the present application, a network where the AP device is located is defined as a first network, and a network identifier of the first network may have multiple implementation manners, for example, the network identifier of the first network may be a device identifier of the AP device, and for example, the network identifier of the first network includes: MAC address of AP device.

In this embodiment of the present application, the AP device first determines a frequency band that is not currently needed by the AP device, and for convenience of description, the frequency band that is not currently needed by the AP device is defined as a "first frequency band". The first frequency band refers to a frequency band that the AP device does not need to use. For example, in step 301, the determining, by the first AP device, the first frequency band that is not needed to be used by the AP device includes:

the AP equipment determines a first frequency band which is not needed to be used by the AP equipment after the frequency band is switched.

In a frequency band switching scene, the AP device uses a first frequency band before performing frequency band switching, and when the AP device performs frequency band switching, the AP device determines that the first frequency band is not needed to be used currently.

302. The AP device generates a first message, wherein the first message comprises: and the first network is a network formed by the AP equipment and the equipment associated with the AP equipment.

In this embodiment of the application, after the AP device determines that the first frequency band is not required To be used in step 301, the AP device may generate a first message according To the first frequency band, where the first message may specifically be a Request message or an indication message, for example, the first message generated by the AP device may be a Request To Send (RTS) message, and the first message may be generated in multiple ways, for example, the AP device may generate the first message through an RTS format extension in a WIFI frame standard protocol, or may customize an individual message control frame, which is not limited herein.

In this embodiment of the application, the AP device carries the network identifier of the first network where the AP device is located in the generated first message, for example, the AP device may use a single field in the first message to carry the network identifier of the first network, or the AP device may use an original field in the first message to carry the network identifier of the first network by modifying a value through the original field. The first network is a network of the AP device and devices associated with the AP device. For example, in the foregoing embodiment, the first network may include a terminal device associated with the AP device, or an AP device cascaded with the AP device, or the like.

In some embodiments of the present application, the step 302 of generating, by the AP device, the first message may specifically include the following steps:

the method comprises the steps that AP equipment configures a broadcast address in a receiving address (Receive address) field of a first message;

the AP device configures a network identifier in a Transmit address (Transmit address) field of the first message.

The first message may have a plurality of fields, for example, the first message includes a frame control field, a receiving address field, and a transmitting address field. The frame control field is used to indicate a frame format of the first message, a value may be a first value, the first value may be used to indicate a message type, the first value may specifically refer to a certain value, for example, the first value may be 00 or 01, and different types of messages are indicated by different values of the frame control field. The received address field is used to indicate the address of the device that can receive the first message, and since the AP device needs to control devices belonging to the first network, the received address field may be configured as a broadcast address, for example, denoted by FF: FF. The sending address field is used for indicating the network sending the first message, for example, the network sending the first message is determined by the network identifier carried in the sending address field. The device receiving the first message may determine that the first message is sent by the AP device in the first network by analyzing the frame control field, the receiving address field, and the sending address field of the first message, and thus may correctly identify the first message sent by the AP device by judging through a combination of a plurality of fields.

In some embodiments of the present application, the first message generated by the AP device may further include: a duration field. Through the duration field, the AP device may indicate a control duration of the controlled device in the first network, for example, if the AP device needs to control the device in the first network to keep silent on the first frequency band, the duration field of the first message may indicate a silence duration configured by the AP device.

303. The AP equipment broadcasts a first message, indicates the first equipment to keep silent on a first frequency band through the first message, and indicates the second equipment not to respond to the first message through the first message, wherein the first equipment is the equipment in a first network receiving the first message, the second equipment is the equipment in a second network receiving the first message, and the second network and the first network have different network identifications.

In this embodiment of the application, after the AP device generates the first message through the foregoing step 302, the AP device sends the first message in a broadcast manner, and the AP device may instruct the first device to keep silent on the first frequency band through the first message and instruct the second device not to respond to the first message through the first message. The first device and the second device both refer to devices that receive the first message, and in addition, the first device is specifically a device in a first network that receives the first message, that is, the first device and the AP device that broadcasts the first message belong to the same network, the second device is a device in a second network that receives the first message, and the second network and the first network have different network identifiers, that is, the second device and the AP device that broadcasts the first message belong to different networks. In this embodiment of the application, the first device may keep silent on the first frequency band after receiving the first message, so that the device in the first network does not contend for the channel resource corresponding to the first frequency band, and therefore, there is no interference of the channel resource. In addition, in this embodiment of the application, although the AP device broadcasts the first message, only the device in the first network will respond to the first message, and the second device does not respond to the first message, so that the first message broadcast by the AP device does not affect the use of the first frequency band by the device in the second network.

In some embodiments of the present application, if the first message generated by the AP device further includes: a duration field. The message processing method provided by the embodiment of the application, besides executing the steps, further includes the following steps:

after the valid time indicated by the duration field is over, the AP device contends for the channel resource corresponding to the first frequency band.

If the AP device can compete for the channel resource corresponding to the first frequency band, the AP device may reuse the channel resource corresponding to the first frequency band, for example, the AP device performs uplink and downlink transmission with a device in the first network.

As can be seen from the foregoing description of the embodiment, the AP device first determines a first frequency band that is not needed to be used by the AP device, and the AP device generates a first message, where the first message includes: the AP equipment broadcasts a first message, indicates the first equipment to keep silent on a first frequency band through the first message, and indicates the second equipment not to respond to the first message through the first message, wherein the first equipment is the equipment in the first network receiving the first message, the second equipment is the equipment in the second network receiving the first message, and the second network and the first network have different network identifications. In this embodiment of the application, for the first frequency band that is not needed to be used, the AP device may instruct the device in the first network where the AP device is located to keep silent on the first frequency band, so that the first device in the first network may keep silent on the first frequency band after receiving the first message, and thus the device in the first network may not contend for the channel resource corresponding to the first frequency band, and thus there is no interference of the channel resource. In addition, in this embodiment of the application, although the AP device broadcasts the first message, only the device in the first network responds to the first message, and does not respond to the device in the second network, so that the first message broadcast by the AP device does not affect the use of the first frequency band by the device in the second network.

401. the first device receives a first message broadcasted by the AP device, wherein the first message comprises: and the first message is used for indicating the first device to keep silent on a first frequency band and indicating the second device not to respond to the first message, wherein the second device is a device in a second network which receives the first message, the second network and the first network have different network identifiers, and the first frequency band is a frequency band which is not needed to be used by the AP device.

In this embodiment of the application, the AP device carries the network identifier of the first network where the AP device is located in the generated first message, for example, the AP device may use a single field in the first message to carry the network identifier of the first network, or the AP device may use an original field in the first message to carry the network identifier of the first network by modifying a value through the original field. After the AP device broadcasts the first message, the first device receives the first message sent by the AP device, and the first device may determine that the received message is the first message broadcast from the AP device by parsing the first message. For example, when the AP device generates the first message, the frame control field, the receiving address field, and the sending address field are configured, so that after the first device receives a certain message, each field in the message may be analyzed, and whether the received message is the first message is determined by values of the frame control field, the receiving address field, and the sending address field.

402. The first device remains silent on the first frequency band in accordance with the first message.

In this embodiment of the application, after the first device receives the first message through the foregoing step 401, the AP device indicates to keep silent on the first frequency band through the first message, and indicates, through the first message, that the second device does not respond to the first message. The first device needs to keep silent on the first frequency band according to the indication of the AP device, so that the first device does not compete for channel resources corresponding to the first frequency band, thereby avoiding interference to the first frequency band, and thus not affecting the use of the first frequency band by the second device.

In some embodiments of the present application, the step 402 of the first device keeping silent on the first frequency band according to the first message includes:

after receiving the first message, the first device analyzes a frame control field, a receiving address field and a sending address field of the first message;

and when the value of the frame control field is a first value, the value of the receiving address field is a broadcast address, and the value of the sending address field is a network identifier, the first device keeps silent on the first frequency band.

The frame control field is used to indicate a frame format of the first message, and a value may be a first value, where the first value refers to a certain value, for example, the first value may be 00 or 01, and different types of messages are indicated by different values of the frame control field. The received address field is used to indicate the address of the device that can receive the first message, and since the AP device needs to control devices belonging to the first network, the received address field may be configured as a broadcast address, for example, denoted by FF: FF. The sending address field is used for indicating the network sending the first message, for example, the network sending the first message is determined by the network identifier carried in the sending address field. The first device may determine that the first message is sent by the AP device in the first network by analyzing the frame control field, the receive address field, and the transmit address field of the first message, and thus may correctly identify the first message sent by the AP device by judging through a combination of a plurality of fields.

In some embodiments of the present application, the first message further comprises: a duration field, and the message processing method provided by the embodiment of the present application further includes:

after the valid time indicated by the duration field is over, the first device contends for the channel resource corresponding to the first frequency band.

If the first device can compete for the channel resource corresponding to the first frequency band, the first device may reuse the channel resource corresponding to the first frequency band, for example, the first device performs uplink and downlink transmission with the AP device in the first network.

As can be seen from the foregoing description of the embodiment, in the embodiment of the present application, for a first frequency band that is not required to be used, an AP device may instruct a device in a first network where the AP device is located to keep silent on the first frequency band, so that the first device in the first network can keep silent on the first frequency band after receiving a first message, and thus the first device does not contend for a channel resource corresponding to the first frequency band, and therefore there is no interference of the channel resource. In addition, in this embodiment of the application, although the AP device broadcasts the first message, only the device in the first network responds to the first message, and does not respond to the device in the second network, so that the first message broadcast by the AP device does not affect the use of the first frequency band by the device in the second network.

In order to better understand and implement the above-described scheme of the embodiments of the present application, the following description specifically illustrates a corresponding application scenario.

Please refer to fig. 5, which is a schematic view illustrating an interaction flow between the AP device and the first device and the second device according to an embodiment of the present application. Next, a manner in which the AP device generates the first message by using an RTS standard message is schematically described, for example, the RTS message generated by the AP device is defined as a special Request To Send, which is abbreviated as SRTS. Firstly, when determining that the first frequency band is not needed to be used, the AP device generates an SRTS request message and broadcasts the SRTS request message, wherein the SRTS request message includes a duration field. The SRTS request message may be received by both the first device and the second device. When the first device receives the SRTS request message, and the first device determines that both the AP device that sends the SRTS request message and the first device are in the first network, the first device keeps silent within the duration specified by the duration field according to the indication of the AP device, and after the duration specified by the duration field is ended, the first device may compete for air interface resources. The second device receives the SRTS request message, and determines that the AP device that sends the SRTS request message and the second device are both in different networks, that is, the second device is in the second network, and the AP device is in the first network, at this time, the second device does not respond to the SRTS request message, and the second device and the AP device perform normal transceiving through an air interface.

Next, the AP device adopts the DBAC mode as an example, and by using the embodiment of the present application, the problem of mutual interference between devices in the DBAC mode can be solved, the problem of interference of the AP device in the DBAC mode to a common AP device in a non-DBAC mode can also be solved, and in addition, the problem of low DBAC mode transmission efficiency when multiple AP devices are deployed can also be solved.

In the embodiment of the application, when the AP device performs frequency band switching, the device associated with the switched frequency band needs to be muted, and the device not associated with the AP device does not need to be muted, so that the AP device can continue to send and receive messages. Therefore, in the embodiment of the present application, the devices associated under a specific AP device can be muted, that is, only the devices within a specific range need to be muted, and no muting is required for other devices not within the specific range.

Fig. 6 is a schematic diagram illustrating a process of processing an SRTS message by a terminal device associated with an AP1 and a terminal device not associated with an AP1 according to an embodiment of the present application. To ensure compliance with Institute of Electrical and Electronics Engineers (IEEE) standards, the RTS standard message may be used to generate the first message based on consideration of minimization of overall system changes. The format of the RTS message is as follows:

the Receive address indicates an address of the receiving device, the Transmit address indicates an address of the transmitting device, and may also indicate a network identifier of the first network where the AP device is located. In the embodiment of the application, the Receive address does not represent a unicast address any more, when the Receive address is set as a broadcast address FF, FF indicates that a first device under the AP device associated with the Transmit address needs a time specified by a silence duration, and a second device under the AP device not associated with the Transmit address does not need to be silent, so that the message can be normally received and sent.

As shown in fig. 6, when the AP device of the Transmit address does not need to use the first frequency band, and the AP device needs to keep silent on the first frequency band, the SRTS request message is sent out, the message is transmitted in the air interface, all devices within the coverage of the AP device can receive the message, and once the message is received, the duration specified by the silent duration field of the air interface can be used for the first device associated with the AP device, and after the duration specified by the duration field is reached, the first device can immediately compete for the air interface to perform normal message transceiving. And for second equipment which is not associated with the AP equipment, ignoring the received SRTS request message, and continuing competing the air interface to receive and transmit the message.

As shown in fig. 7, a schematic diagram of a processing procedure of a Network Allocation Vector (NAV) after receiving an SRTS message is provided for a terminal device associated with an AP1 and a terminal device not associated with an AP1 according to the embodiment of the present application. In virtual carrier sensing, the STA device associated with the AP1 updates the NAV to the specified duration of the duration field, and silences the air interface to stop sending the message. The NAV of the STA device not associated with the AP1 is not affected by the message, and the STA device can normally compete for an air interface and transmit and receive a message within a specified duration of a duration field, thereby implementing silence of a specific WIFI device in the entire WIFI system.

Fig. 8 is a schematic diagram illustrating a processing procedure of a first message by a message processing device according to an embodiment of the present application. The message processing equipment can comprise two parts of message identification and first message processing, firstly, the message processing equipment can identify the field of the message type through a Frame control field, judge whether the message is an SRTS message through whether the received address is FF, FF and FF, and further judge whether the Transmit address is a network identifier associated with the equipment. If yes, entering a first message processing part, otherwise, returning to not do any processing. All the devices in the same channel can receive the first message, and after recognizing that the first message is sent by the AP device through the transmit address and the receiving address, the first device will keep silent, and the second device will not respond to the first message, and the second device will continue normal message transceiving. In the first message processing part, the message processing apparatus may start from the reception of the SRTS message by the time indicated by the silence duration field.

In the embodiment of the application, the received address field is FF, the TransmitAddress field is the MAC address of the AP device, the first message indicates the time that the device associated with the Transmit address AP device needs the indication of the silence duration field, and the STA not associated with the AP device does not need to silence and can work normally.

The first message provided by the embodiment of the application has good compatibility, the format of the RTS message is not changed by the first message, all AP equipment can normally recognize the message, and the RTS message is processed by default. According to the method for silencing the equipment in the specific range, the equipment silencing control function in the specific range is introduced into the WIFI standard, and the problem of DBAC mutual interference can be solved.
