A communication method and apparatus according to an embodiment of the present application are described below with reference to the drawings.

Referring to fig. 1, a flow 100 of one embodiment of a communication method according to the present application is shown. The communication method comprises the following steps:

step 101, responding to that the gateway device is in a data communication state, broadcasting a first beacon frame according to a set data communication rule in each period, wherein the first beacon frame comprises first indication information indicating whether there is data to be transmitted to the terminal device.

The executing subject for the communication method of the present embodiment may be a gateway device that can establish a network connection with at least one terminal device. In some embodiments, the terminal device may be battery powered, a low power device, and the gateway device may be grid powered.

For example, the terminal device may be various electronic devices, including but not limited to a smart phone, a tablet computer, a wearable device, a vehicle-mounted device, an Augmented Reality (AR)/Virtual Reality (VR) device, an ultra-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA), an e-book reader, an MP3 (Moving Picture Experts Group Audio Layer III, Moving Picture Experts compression standard Audio Layer 3) player, an MP4 (Moving Picture Experts Group Audio Layer IV) player, a laptop portable computer, a desktop computer, a smart meter, a smart water meter, a smart eye, a gateway, and other electronic devices.

In this embodiment, when the gateway device is in a data communication state, the gateway device may perform data interaction with the terminal device connected thereto. For example, the gateway device may enter a data communication state after performing network entry configuration for the terminal device.

In addition, in the data communication state, the gateway device broadcasts the first beacon frame periodically, for example, in each period, the gateway device broadcasts the first beacon frame according to the set data communication rule.

For the first beacon frame, first indication information indicating whether there is data to be transmitted to the terminal device may be included. Specifically, the gateway device may determine whether there is data to be transmitted to the terminal device, and if there is data to be transmitted, the first identification bit in the first beacon frame may be set to an identification of "there is data to be transmitted", and at the same time, the first beacon frame is made to carry device information of the terminal device, so that the terminal device may determine whether to receive the data. If there is no data to transmit, then the first identification bit in the first beacon frame may be set to the identification of "no data to transmit".

And 102, responding to the first indication information indicating that data is transmitted to the terminal equipment, and transmitting the data to the terminal equipment specified by the first indication information.

In this embodiment, if the gateway device determines that there is data to be transmitted to the terminal device, the gateway device may transmit the data to the terminal device. Of course, the gateway device does not transmit data to the terminal device if it determines that there is no data to transmit to the terminal device.

It is understood that the terminal device may enter a low power consumption state, such as turning off a radio frequency switch, etc., when the gateway device is not transmitting data to the terminal device.

According to the method provided by the embodiment of the application, the gateway device periodically broadcasts the first beacon frame, wherein the first beacon frame comprises the first indication information indicating whether data are transmitted to the terminal device, the first beacon frame responds to the first indication information indicating that the data are transmitted to the terminal device, and transmits the data to the terminal device specified by the first indication information, so that the power consumption of the terminal device is reduced, the power consumption is reduced, the data conflict is reduced, the network is not blocked, the downlink data of the gateway can be transmitted in time, the response speed of the network is effectively improved, and the optimization effect on a system with higher response time requirement is good.

In some alternative implementations of this embodiment, each cycle includes a plurality of slots, for example 16 slots. When the gateway device is connected with at least one terminal device, at least one time slot of the plurality of time slots corresponds to the at least one terminal device respectively for data interaction.

For example, assuming that each cycle includes 16 time slots, the gateway device is connected with a terminal device a, a terminal device B, and a terminal device C. Terminal a may correspond to a first time slot, terminal B may correspond to a second time slot, and terminal C may correspond to a third time slot. That is, the terminal device a may perform data interaction with the gateway device at the first time slot; the terminal device B may perform data interaction with the gateway device at the second time slot; and the terminal device C can perform data interaction with the gateway device in the third time slot. Therefore, each terminal device performs data interaction with the gateway device at the designated time sequence, and data collision can be reduced.

In some embodiments, in response to the first indication information indicating that there is data to transmit to the terminal device, transmitting the data to the terminal device specified by the first indication information comprises:

and in response to the first indication information indicating that there is data to be transmitted to the terminal device, transmitting the data to the terminal device in a time slot corresponding to the terminal device specified by the first indication information.

That is, the gateway device may transmit data to each terminal device in the time slot corresponding to the terminal device.

The description continues by taking an example in which each period includes 16 time slots, and the gateway device is connected with a terminal device a, a terminal device B, and a terminal device C. And if the data are transmitted to the terminal device A, transmitting the data to the terminal device A in the first time slot corresponding to the terminal device A. And if the data are transmitted to the terminal equipment B, transmitting the data to the terminal equipment B in a second time slot corresponding to the terminal equipment B. If no data is to be transmitted to the terminal device C, no data needs to be transmitted to the terminal device C in the third timeslot corresponding to the terminal device C.

Additionally, in some embodiments, the method further comprises: and receiving the data transmitted by the terminal equipment in the time slot corresponding to the terminal equipment designated by the first indication information.

That is, if the terminal device has data to transmit to the gateway device, the terminal device may also transmit the data to the gateway device in the time slot corresponding to the terminal device. In this way, the gateway device may also receive the data transmitted by the terminal device in the timeslot corresponding to the terminal device.

In some embodiments, broadcasting the first beacon frame according to the set data communication rule in each period comprises: at each cycle, at least one time slot is determined from the plurality of time slots, and a first beacon frame is broadcast at each of the at least one time slot.

That is, when the gateway device connects to at least one terminal device, the first beacon frame may be broadcast at a time slot corresponding to each terminal device, so that each terminal device receives the first beacon frame at the corresponding time slot.

The description continues by taking an example in which each period includes 16 time slots, and the gateway device is connected with a terminal device a, a terminal device B, and a terminal device C.

The gateway device may broadcast a first beacon frame when reaching a first time slot of each cycle, and the terminal device a may wake up at the first time slot and receive the first beacon frame. When the gateway device reaches the second time slot of each cycle, the gateway device may broadcast the first beacon frame, and the terminal device B may wake up at the second time slot, and receive the first beacon frame, and if there is data to be transmitted to the terminal device B, the gateway device may transmit the data to the terminal device B at the second time slot corresponding to the terminal device B, and the terminal device B may also receive the data at the second time slot. When the gateway device reaches the third time slot of each period, the gateway device may broadcast the first beacon frame, and the terminal device C wakes up at the third time slot, and receives the first beacon frame.

In addition, the gateway device does not transmit the first beacon frame in the remaining time slots of each cycle, nor transmit data.

Therefore, each terminal device performs data interaction with the gateway device at the specified time sequence, so that data conflict can be reduced, the response speed of the network can be effectively improved, and the power consumption of the terminal device can be reduced.

In other embodiments, broadcasting the first beacon frame according to the set data communication rule in each period includes: in the first slot of each cycle, a first beacon frame is broadcast.

That is, when the gateway device connects to at least one terminal device, the gateway device may broadcast the first beacon frame at the first time slot of each cycle, so that each terminal device may receive the first beacon frame at the first time slot.

When the gateway device reaches the first time slot of each period, the gateway device may broadcast a first beacon frame, and each terminal device connected to the gateway device may wake up at the first time slot and receive the first beacon frame, that is, terminal device a, terminal device B, and terminal device C may wake up at the first time slot and receive the first beacon frame.

If the gateway device has data to transmit to the terminal device a, the gateway device transmits the data to the terminal device a in the first time slot corresponding to the terminal device a, and the terminal device a may also receive the data in the first time slot. If the gateway device has data to transmit to the terminal device B, the gateway device transmits the data to the terminal device B in the second time slot corresponding to the terminal device B, and the terminal device B may wake up and receive the data in the second time slot. If the gateway device does not have data to transmit to the terminal device C, the gateway device does not need to transmit data to the terminal device C in the third time slot corresponding to the terminal device C.

Therefore, each terminal device performs data interaction with the gateway device at the designated time sequence, so that data conflict can be reduced, the response speed of the network can be effectively improved, and the power consumption of the terminal device can be reduced.

In some embodiments, the first beacon frame further includes slot information, which is used to determine a wake-up time of the terminal device, so as to wake up the terminal device at the wake-up time, so that the terminal device can perform data interaction with the gateway device.

That is to say, the gateway device may transmit the timeslot information to each terminal device through the first beacon frame, and each terminal device may also determine the time of the next wake-up according to the received timeslot information. It should be noted that the time slot information may be a time slot in which the gateway device is currently located, or may directly specify an awake time slot of the terminal device.

For example, when the gateway device transmits a first beacon frame to the terminal device a at a first time slot of a current cycle, the first beacon frame may include information indicating that the gateway device is at the first time slot or instruct that the terminal device a wakes up at the first time slot of a next cycle, and the terminal device a may determine a time of the next cycle wake-up after receiving the first beacon frame. Similarly, when the gateway device transmits a first beacon frame to terminal device B at the second slot of the current cycle, the first beacon frame may include information indicating that the gateway device is at the second slot or that terminal device B wakes up at the second slot of the next cycle, and terminal device B may determine the time of the next cycle wake-up after receiving the first beacon frame.

For another example, when the gateway device sends the first beacon frame to the terminal device a and the terminal device B at the first timeslot of the current cycle, the first beacon frame may include information indicating that the gateway device is at the first timeslot or indicate that each terminal device wakes up at the timeslot of the next cycle, and after receiving the first beacon frame, the terminal device a and the terminal device B may respectively determine the time when they wake up at the next cycle.

At the wake-up time, the terminal device may be woken up, e.g., turn on the radio frequency switch, thereby enabling the terminal device to perform data interaction with the gateway device, e.g., receive the first beacon frame.

Therefore, time synchronization between the gateway equipment and the terminal equipment is realized, the collision probability of equipment communication in the network can be reduced through the time synchronization, downlink data of the gateway equipment can be transmitted in time, and the response speed of the network is improved.

In some embodiments, each of the at least one time slot is divided into a first time period and a second time period, and the first time period is a time period for data interaction with the terminal device; and the second time interval is a time interval for stopping data interaction with the terminal equipment.

That is, the time slot may include a first period t1 (which may also be an active period) and a second period t2 (which may also be referred to as a sleep period). In the non-working time slot and the dormant period of the working time slot of each terminal device, the gateway device does not perform data interaction with the terminal device, so that the terminal device can enter a low power consumption mode. This reduces power consumption of the terminal device.

With further reference to fig. 2, a flow 200 of yet another embodiment of a communication method is shown. The communication method comprises the following steps:

step 201, responding to the gateway device being in the networking state, broadcasting a second beacon frame according to a set network access rule in each period, wherein the second beacon frame includes third indication information indicating a network access permission state.

The execution subject for the communication method of the present embodiment may be a gateway apparatus.

When the gateway equipment is in a networking state, the network access authority of the gateway equipment is opened, and at the moment, other terminal equipment which is not connected to the gateway equipment is allowed to establish network connection with the gateway equipment.

In the networking state, the gateway device broadcasts the second beacon frame periodically, for example, at the first time slot of each period.

For the second beacon frame, third indication information indicating a network access authority state may be included. Specifically, the gateway device may open the access right, and set the second identification bit in the second beacon frame to be the identifier that "the access right is opened".

Step 202, receiving a network access request sent by a terminal device, where the network access request is used to request a gateway device to execute network access configuration on the terminal device.

Step 203, network access configuration of the terminal equipment is executed.

In this embodiment, the gateway device periodically broadcasts the second beacon frame, the terminal device actively scans when joining the network, and after receiving the second beacon frame, the terminal device performs networking operation according to information carried in the second beacon frame, for example, sends a network access request to the gateway device.

And the gateway equipment receives the network access request sent by the terminal equipment and executes network access configuration on the terminal equipment according to the network access request.

In some embodiments, the network access request further carries device information of the terminal device, and the performing network access configuration on the terminal device includes:

determining a network address to be allocated to the terminal equipment, and sending the network address to the terminal equipment; and/or the presence of a gas in the gas,

and recording the equipment information of the terminal equipment in the equipment list.

That is, the gateway device may send the network address of the terminal device to the terminal device after receiving the network access request sent by the terminal device, and send the network address to the terminal device, and record the device information of the terminal device in the device list.

Further, after completing the network access configuration of the terminal device, the gateway device may close the network access right.

Therefore, according to the method provided by the embodiment of the application, the second beacon frame is periodically broadcast through the gateway device, and the network access configuration of the terminal device is executed according to the network access request sent by the terminal device, so that the power consumption of the terminal device is reduced, and the power consumption is reduced.

Referring to fig. 3, a flow 300 of one embodiment of a method of communication according to the present application is shown. The communication method comprises the following steps:

step 301, when the terminal device is connected to the gateway device, receiving a first beacon frame broadcast by the gateway device every period, where the first beacon frame includes first indication information indicating whether there is data to be transmitted to the terminal device.

The execution subject for the communication method of the present embodiment may be a terminal device. The terminal device may establish a network connection with the gateway device. In some embodiments, the terminal device may be battery powered, a low power device, and the gateway device may be grid powered.

In this embodiment, when the gateway device periodically broadcasts the first beacon frame, if the terminal device is in an awake state, for example, the radio frequency switch is turned on, the first beacon frame broadcasted by the gateway device may be received.

For the first beacon frame, first indication information indicating whether there is data to be transmitted to the terminal device may be included. Specifically, the terminal device may determine whether the gateway device has data to transmit to the terminal device itself according to the information in the first beacon frame, for example, the terminal device may determine that the gateway device has data to transmit according to an identifier "having data to transmit" in the first beacon frame, and may also determine that the data is to be transmitted to the terminal device itself according to the device information of the terminal device carried in the first beacon frame. As another example, the terminal device may determine that the gateway device has no data to transmit based on the identification of "no data to transmit" in the first beacon frame. Accordingly, the terminal device can determine whether to receive data through the first beacon frame.

Step 302, determining that there is data to be transmitted to the terminal device according to the first indication information.

Step 303, receiving data transmitted by the gateway device.

In this embodiment, if the terminal device determines that the gateway device has data to transmit, the terminal device may receive the data transmitted by the gateway device. In addition, if the terminal device determines that the gateway device has no data to transmit and does not have data to transmit to the gateway device, the terminal device may enter a low power consumption state, for example, turn off the rf switch.

In some optional implementations of this embodiment, the method further includes:

in response to there being data to transmit the gateway device, transmitting the data to the gateway device.

In this embodiment, the terminal device may also determine whether there is data to be transmitted to the gateway device, and if there is data to be transmitted to the gateway device, the terminal device may transmit the data to the gateway device. If there is no data to transmit to the gateway device and the terminal device has no data to transmit to the gateway device, the terminal device may enter a low power state, such as turning off a radio frequency switch.

According to the communication method provided by the embodiment of the application, the terminal device receives the first beacon frame broadcasted by the gateway device, the first beacon frame comprises the first indication information indicating whether data are transmitted to the terminal device, and the data transmitted by the gateway device are received by determining whether the data are transmitted to the terminal device according to the first indication information, so that the power consumption of the terminal device is reduced, the power consumption is reduced, and the data conflict is reduced, so that the network is not congested, the downlink data of the gateway can be transmitted in time, the response speed of the network is effectively improved, and the system with higher response time requirement has a good optimization effect.

In some alternative implementations of this embodiment, each cycle includes a plurality of slots. One of the time slots corresponds to the terminal device for data interaction.

For example, assuming that each period includes 16 time slots, if the terminal device is a terminal device a connected to the gateway device, the terminal device a may correspond to the first time slot, that is, the terminal device a may perform data interaction with the gateway device in the first time slot; if the terminal device is a terminal device B connected with the gateway device, the terminal device B can correspond to the second time slot, and the terminal device B can perform data interaction with the gateway device in the second time slot; if the terminal device is a terminal device C connected to the gateway device, the terminal device C may correspond to the third time slot, and the terminal device C may perform data interaction with the gateway device at the third time slot. Therefore, each terminal device performs data interaction with the gateway device at the designated time sequence, and data collision can be reduced.

In some embodiments, in response to the first indication information indicating that there is data to be transmitted to the terminal device, receiving the data transmitted by the gateway device includes:

and receiving the data transmitted by the gateway equipment in a time slot corresponding to the terminal equipment in a plurality of time slots in response to the first indication information indicating that the data is transmitted to the terminal equipment.

That is, the terminal device may receive the data transmitted by the gateway device at its corresponding time slot.

For terminal device a, if the gateway device has data to transmit to terminal device a, terminal device a may receive the data transmitted by the gateway device in the corresponding first time slot.

This reduces power consumption of the terminal device.
