Detailed Description

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.

Currently, there is no spectrum scheme specified in the LoRa specification for how LoRa operates at 800 MHz. In the 800MHz band, 821-.

One of the core concepts of the embodiments of the present application is that, in an 800MHz frequency band, setting an uplink channel and a downlink channel can simultaneously support two different channel frequency widths, and how a terminal uses the two channel frequency widths to perform uplink and downlink communication is specified.

The two channel frequency widths may be set according to information such as a communication protocol (e.g., LoRa protocol, NB-IoT protocol, WIFI protocol, etc.) used by the terminal, hardware parameters of the terminal, and service requirements in an actual application scenario.

The terminal can be an LoRa terminal in the embodiment of the application, and two channel frequency widths can be set for an uplink channel and a downlink channel by considering the specification of a LoRa chip and the requirement of micropower short-distance communication, wherein one frequency width is 125KHz, and the other frequency width is 500 KHz. The frequency widths of the two channels may also be set to other values, which is not limited in this embodiment of the present application.

Referring to fig. 1, a schematic diagram of uplink channel resource division by 821-824MHz spectrum resources in this embodiment is shown.

The design of the channel scheme mainly refers to the capability parameters of an LoRa chip, and the LoRa chip can receive data of 8 125KHz and 1 500KHz channels at most in parallel at present. The uplink channel is divided into 15 channel spectrum resources of 125KHz and 2 channel spectrum resources of 500 MHz.

Fig. 2 is a schematic diagram illustrating that 866-869MHz spectrum resources divide downlink channel resources in the embodiment of the present application.

By taking the reference of the capability parameters of the LoRa chip, the downlink channel is totally divided into 15 channel spectrum resources of 125KHz and 5 channel spectrum resources of 500 MHz.

In the following, how to use two channel frequency widths for up-and-down communication is further described.

Referring to fig. 3, a flowchart illustrating a first step of a first embodiment of a method for a terminal to communicate with a base station according to the present application is shown, which may specifically include the following steps:

step 101, the terminal sends a first message to at least one first base station through a first uplink channel, the first message is used for requesting to access a network, and the first channel is in a first uplink channel set;

the terminal may broadcast a first message to at least one first base station over a first uplink channel to access the network. Specifically, the first message may be a join-request message (join-request), and the first base station may forward the first message to the server, where the server authenticates the network entry.

After allowing the terminal to access the network, the server may send a network access response message (join-accept) to the second base station, and the second base station forwards the network access response message to the terminal.

The first base station and the second base station may be the same base station or different base stations.

In this embodiment, the first uplink channel set may be a set of uplink channels divided in an 800MHz frequency band. For example, the first set of uplink channels may be a set of 821-.

The first upstream channel may be a 125KHz channel or a 500KHz channel. The terminal can select a 125KHz channel or a 500KHz channel according to data to be transmitted or a service to be performed. For example, when smaller data needs to be transmitted, a 125KHz channel with a smaller frequency width is selected; when larger data needs to be transmitted, a 500KHz channel with larger frequency width is selected.

102, the terminal receiving a second message from a second base station through a first downlink channel, where the first downlink channel is in a first downlink channel set, the second message including a channel mask, where the channel mask is used to indicate availability of a first uplink channel subset or a first downlink channel subset, where the first uplink channel subset is in the first uplink channel set, and the first downlink channel subset is in the first downlink channel set;

the first set of downlink channels may be a set of downlink channels divided in an 800MHz frequency band. For example, the first set of downlink channels may be a set of 866-869MHz channels, which may include 15 125KHz channels and 5 500MHz channels.

The second message may be a join-accept message (join-accept), and the second message may include a channel mask (ChannelMask), where the channel mask may indicate availability of the first uplink channel subset or the first downlink channel subset.

In one example, the first subset of uplink channels may refer to a subset of 500KHz uplink channels and the first subset of downlink channels may refer to a subset of 500KHz downlink channels. The availability indicates whether a base station capable of supporting a 500KHz uplink channel or a downlink channel is available.

In an actual deployed base station, some base stations may not be configured with 500KHz channels, and if there is a base station capable of supporting 500KHz uplink channels or downlink channels among the base stations capable of communicating with the terminal, the channel mask may indicate that the first subset of uplink channels or the first subset of downlink channels has availability. If there is no base station capable of supporting the 500KHz uplink channel or the downlink channel among the base stations capable of communicating with the terminal, the channel mask may indicate that the first subset of uplink channels or the first subset of downlink channels has no availability. When the first uplink channel subset does not have availability, the terminal can only transmit data on the 125KHz uplink channel; when the first subset of downlink channels does not have availability, the terminal can only receive data on the 125KHZ downlink channel.

103, the terminal sends data to the at least one first base station through a second uplink channel, or receives data from a third base station through a second downlink channel, where the second uplink channel is in the first uplink channel subset, and the second downlink channel is in the first downlink channel subset; the frequency width of the second uplink channel is greater than that of a third uplink channel, and the third uplink channel is any other channel in the first uplink channel set except for the first uplink channel subset; the frequency width of the second downlink channel is greater than the frequency width of a third downlink channel, and the third downlink channel is any other channel in the first downlink channel set except for the first downlink channel subset.

When the first uplink channel subset has availability, the terminal may determine a second uplink channel in the first uplink channel subset, and transmit data to the first base station through the second uplink channel.

The frequency width of the second uplink channel is greater than that of a third uplink channel, and the third uplink channel is any other channel in the first uplink channel set except for the first uplink channel subset. In particular, the third upstream channel may be a 125KHz upstream channel and the first subset of upstream channels may be a subset of 500KHz upstream channels.

When the first downlink channel subset has availability, the terminal may determine a second downlink channel in the first downlink channel subset, and receive data from the third base station through the second downlink channel.

The frequency width of the second downlink channel is greater than that of the third downlink channel, and the third downlink channel is any other channel in the first downlink channel set except for the first downlink channel subset. In particular, the third downlink channel may be a 125KHz downlink channel, and the first subset of downlink channels may be a subset of 500KHz downlink channels.

In the embodiment of the application, the terminal can be a LoRa terminal operating in a Class B mode, and the Class B mode can also be called a Beacon mode. In the ClassB mode, the terminal periodically wakes up and receives downlink data. A terminal in Class B mode has more periodic receive slots, and in addition to the random receive window of Class a, Class B devices open another receive window, such as a burst slot (pingslot), at a specified time. In order for the terminal to open a reception window at a designated time, the terminal needs to receive a time-synchronized Beacon (Beacon) from the base station. Therefore, the server can also know the time of all receiving windows of the terminal equipment.

In the Class B mode LoRa, the step of receiving, by the terminal, data from the third base station through the second downlink channel may include: the terminal determines a second downlink channel and configures the second downlink channel as a downlink channel of a pulse time slot; and the terminal receives the data sent by the third base station in the pulse time slot through the second downlink channel.

In this embodiment of the present application, the second message may further include first information, where the first information may be used to indicate a determination manner of a downlink channel of the burst timeslot;

the step of the terminal determining the second downlink channel and configuring the second downlink channel as the downlink channel of the burst slot may further include: the terminal determines a determining mode of a downlink channel of a pulse time slot corresponding to the first information; and the terminal determines a second downlink channel by adopting the determination mode and configures the second downlink channel as a downlink channel of the pulse time slot.

Referring to fig. 4, a flowchart illustrating a first step of a first embodiment of a method for a terminal to communicate with a server according to the present application is shown, which may specifically include the following steps:

step 201, a server obtains the received signal strength and the service type of data received by a first base station and sent by a terminal through a fourth uplink channel;

in this embodiment, the terminal may send data to the first base station through the fourth uplink channel. The first base station may determine the signal strength of the received data and determine the type of service being performed by the terminal. The server may obtain the received signal strength and the type of service determined by the first base station.

The server may include a server or a server cluster, and is configured to perform service processing according to data acquired from a base station or a terminal, and control an operating mode and an operating state of the base station or the terminal. In all embodiments of the present application, the server may also be called a web server.

The service types may be distinguished according to actual application scenarios.

For example, in a positioning scenario, positioning may be performed according to communication between a terminal and a base station, and the service type may be a positioning service.

For another example, in a monitoring scenario, the terminal may send the collected monitoring data to the base station, and the service type may be a monitoring service.

For another example, in a video-on-demand scenario, the terminal may obtain a video stream on demand from the base station, and the service type may be an on-demand service.

Step 202, the server sends a third message to the terminal through a second base station according to the received signal strength and the service type; the third message comprises a channel identifier of a fifth uplink channel or a channel identifier of a fourth downlink channel; the frequency width of the fifth uplink channel is greater than the frequency width of the fourth uplink channel, and the fourth uplink channel and the fifth uplink channel are in a second uplink channel set; the frequency width of the fourth downlink channel is greater than the frequency width of a fifth downlink channel, and the fourth downlink channel and the fifth downlink channel are in a second downlink channel set.

In this embodiment, the second set of uplink channels may be a set of uplink channels divided in the 800MHz frequency band. For example, the second set of uplink channels may be a set of 821-.

And the fourth uplink channel and the fifth uplink channel both belong to the second uplink channel set, and the frequency width of the fifth uplink channel is greater than that of the fourth uplink channel. Specifically, the fifth upstream channel may be a 500KHz upstream channel, and the fourth upstream channel may be a 125KHz upstream channel.

The server may determine whether the uplink channel of the terminal needs to be adjusted according to the received signal strength and the service type of the data sent by the terminal and received by the first base station. If so, the server may send a third message with the channel identifier of the fifth uplink channel to the terminal through the second base station. After receiving the third message with the channel identifier of the fifth uplink channel, the terminal may adjust the uplink channel to the fifth uplink channel with a wider frequency width.

For example, the server determines that the terminal needs to upload a video stream with a large data volume according to the received signal strength and the service type of the data sent by the first base station receiving terminal, and then the server may send a message to the terminal through the second base station to instruct the terminal to switch to an uplink channel with a wider frequency width.

In this embodiment, the second downlink channel set may be a set of downlink channels divided in an 800MHz frequency band. For example, the second set of downlink channels may be a set of 866-869MHz channels, which may include 15 125KHz channels and 5 500MHz channels.

And the fourth downlink channel and the fifth downlink channel both belong to the second downlink channel set, and the frequency width of the fourth downlink channel is greater than that of the fifth downlink channel. Specifically, the fourth downlink channel may be a 500KHz downlink channel, and the fifth downlink channel may be a 125KHz downlink channel.

The server may determine whether the downlink channel of the terminal needs to be adjusted according to the received signal strength and the service type of the data sent by the terminal and received by the first base station. If so, the server may send a third message with the channel identifier of the fourth downlink channel to the terminal through the second base station. After receiving the third message with the channel identifier of the fourth downlink channel, the terminal may adjust the downlink channel to the fourth downlink channel with a wider frequency width.

For example, the server determines that a video stream with a large data volume needs to be sent to the terminal according to the received signal strength and the service type of the data sent by the first base station receiving terminal, and then the server may send a message to the terminal through the second base station to instruct the terminal to switch to a downlink channel with a wider frequency width.

In this embodiment, the server may send, to the terminal through the second base station, a third message according to the received signal strength and the service type of the data received by the first base station and sent by the terminal through the fourth uplink channel; the third message may include a channel identifier of a fifth uplink channel or a channel identifier of a fourth downlink channel; the terminal may switch to a fifth uplink channel with a wider frequency width according to the channel identifier of the fifth uplink channel, or switch to a fourth downlink channel with a wider frequency width according to the channel identifier of the fourth downlink channel. In the frequency band of 800MHz, the terminal can switch to the 500KHz uplink channel according to the channel identifier indicating the 500KHz uplink channel in the message sent by the server; or, the terminal switches to the 500KHz downlink channel according to the channel identifier indicating the 500KHz downlink channel in the message sent by the server, so that the terminal can realize the switching of the uplink channel and the downlink channel in the 800MHz frequency band.

Fig. 4 illustrates an embodiment of how the server controls the terminal to switch the uplink channel or the downlink channel from the perspective of the server. Corresponding to the embodiment described in fig. 4, the following embodiment describes that, from the perspective of the terminal, the terminal can switch the uplink channel or the downlink channel according to the message sent by the server.

step 301, the terminal sends data to the first base station through a fourth uplink channel;

after receiving the data sent by the terminal through the fourth uplink channel, the first base station may determine the signal strength of the received data and determine the type of service performed by the terminal, and then send the signal strength of the received data and the type of service of the terminal to the server.

Step 302, the terminal receives a third message sent by the server through the second base station, where the third message includes a channel identifier of a fifth uplink channel or a channel identifier of a fourth downlink channel;

step 303, the terminal sends data to the first base station through the fifth uplink channel according to the channel identifier of the fifth uplink channel; the terminal receives data sent by the first base station through the fourth downlink channel according to the channel identifier of the fourth downlink channel; the frequency width of the fifth uplink channel is greater than the frequency width of the fourth uplink channel, and the fourth uplink channel and the fifth uplink channel are in a second uplink channel set; the frequency width of the fourth downlink channel is greater than the frequency width of a fifth downlink channel, and the fourth downlink channel and the fifth downlink channel are in a second downlink channel set.

The server may determine whether the uplink channel of the terminal needs to be adjusted according to the received signal strength and the service type of the data sent by the first base station receiving terminal. If so, the server may send a third message with the channel identifier of the fifth uplink channel to the terminal through the second base station. After receiving the third message with the channel identifier of the fifth uplink channel, the terminal may adjust the uplink channel to the fifth uplink channel with a wider frequency width.

Or, the server may determine whether the downlink channel of the terminal needs to be adjusted according to the received signal strength and the service type of the data sent by the first base station receiving terminal. If so, the server may send a third message with the channel identifier of the fourth downlink channel to the terminal through the second base station. After receiving the third message with the channel identifier of the fourth downlink channel, the terminal may adjust the downlink channel to the fourth downlink channel with a wider frequency width.

Referring to fig. 6, a flowchart illustrating steps of a second embodiment of a method for a terminal to communicate with a base station according to the present application is shown, which may specifically include the following steps:

step 401, the terminal sends a fourth message to at least one first base station through a sixth uplink channel, where the fourth message is used to request access to a network, and the sixth uplink channel is in a third uplink channel set;

in this embodiment of the present application, the third uplink channel set may be a set of uplink channels obtained by dividing in an 800MHz frequency band. For example, the third set of uplink channels may be a set of 821-.

The terminal may broadcast the fourth message to the at least one first base station through the sixth uplink channel to access the network. Specifically, the fourth message may be a join-request message (join-request), and the first base station may forward the fourth message to the server, where the server authenticates the network entry.

Step 402, the terminal receives a fifth message from the second base station through a sixth downlink channel, where the sixth downlink channel is in a third downlink channel set;

the third downlink channel set may be a set of downlink channels obtained by dividing in the 800MHz frequency band. For example, the third set of downlink channels may be a set of 866-869MHz channels, which may include 15 125KHz channels and 5 500MHz channels.

The fifth message may be a join-accept message. After allowing the terminal to access the network, the server may send a network access response message to the second base station, and the second base station forwards the network access response message to the terminal.

Step 403, the terminal determines a seventh downlink channel or an eighth downlink channel according to the fifth message; the seventh downlink channel is in a second downlink channel subset, the eighth downlink channel is in a third downlink channel subset, the second downlink channel subset and the third downlink channel subset are in the third downlink channel set, and the frequency width of the channels in the second downlink channel subset is greater than the frequency width of the channels in the third downlink channel subset;

in the 800MHz band, the second downlink channel subset may be a subset of 500KHz downlink channels in the 866-869MHz channel set, and the third downlink channel subset may be a subset of 125KHz downlink channels.

The terminal may determine, according to a fifth message sent by the server through the second base station, a seventh downlink channel with a larger frequency width or an eighth downlink channel with a smaller frequency width. The terminal may configure the seventh downlink channel as a downlink channel, and receive data sent by the second base station through the seventh downlink channel; or configuring the eighth downlink channel as a downlink channel, and receiving the data sent by the second base station through the eighth downlink channel.

In an embodiment of the present application, the fifth message may include a channel mask; the channel mask may indicate the availability of a second subset of uplink channels or a second subset of downlink channels; step 403 may further include the sub-steps of:

substep S11, if the channel mask indicates that the second downlink channel subset is unavailable, the terminal determines an eighth downlink channel according to the fifth message;

specifically, the second downlink channel subset may be a 500KHz downlink channel subset, and if the second downlink channel subset is not available, the terminal may only determine the eighth downlink channel from the 125KHz third downlink channel subset.

Or, in sub-step S12, if the channel mask indicates that the second subset of downlink channels is available, the terminal determines the seventh downlink channel or the eighth downlink channel according to the fifth message.

If the second downlink channel subset is available, the terminal may determine the seventh downlink channel from the second downlink channel subset, or may determine the eighth downlink channel from the third downlink channel subset.

In this embodiment of the application, the fifth message may further include second information, where the second information may indicate a manner of determining the downlink channel, and the sub-step S12 may further include:

substep S121, if the second information is the first identifier, the terminal determines a seventh downlink channel from the second downlink channel subset;

in one example, if the second information is the first identifier, the terminal determines the downlink channel in the 125KHz channel subset using a calculation formula of the 125KHz channel. The second information may be burst slot type information (PingslotType), for example, the first identifier may be PingslotType ═ 0.

The calculation formula for the 125KHz channel may be:

wherein, the DevAddr is a terminal identifier, and may be composed of numbers with preset length. beacon _ time is the beacon frame time, which is the time carried in the bcnppayload field. beacon _ period is the beacon frame period. floor () is a floor function and modulo is a modulo operation.

By which one of the 15 125KHz downstream channels can be determined for use. The numerical parameters in this formula can be adjusted according to the number of actually divided 125KHz downstream channels.

In the substep S122, if the second information is the second identifier, the terminal determines an eighth downlink channel from the third downlink channel subset;

and if the second information is the second identifier, the terminal determines the downlink channel in the 500KHz channel subset by using a calculation formula of the 500KHz channel. For example, the second flag is PingslotType ═ 1.

The calculation formula for the 500KHz channel may be:

by this formula one can be determined to use among 5 500KHz downstream channels. The digital parameters in the formula can be adjusted according to the number of actually divided downlink channels of 125KHz and 500 KHz.

And a substep S123, if the second information is the third identifier, determining, by the terminal, a seventh downlink channel or an eighth downlink channel from the third downlink channel set.

If the second information is the third identifier, the terminal may determine the downlink channel in the 125KHz and 500KHz channel subsets using a calculation formula of the mixed channel scheme. For example, the third identifier may be PingslotType 2.

The calculation formula of the mixed channel scheme may be:

by this formula one can be determined to use among 15 downstream channels of 125KHz and 5 downstream channels of 500 KHz. The digital parameters in the formula can be adjusted according to the number of actually divided downlink channels of 125KHz and 500 KHz.

Step 404, the terminal receives data sent by the second base station through the seventh downlink channel or the eighth downlink channel.

In this embodiment of the present application, if the terminal is a LoRa terminal operating in a Class B mode, step 404 may include: the terminal configures the seventh downlink channel or the eighth downlink channel as a downlink channel of the pulse time slot; and the terminal receives the data sent by the second base station in the pulse time slot in the seventh downlink channel or the eighth downlink channel.

In this embodiment of the present application, after sending a fourth message for requesting to access a network to a base station, a terminal may receive a fifth message returned by the base station; and according to the fifth message, determining whether a seventh downlink channel with larger frequency width or an eighth downlink channel with smaller frequency width is selected as the downlink channel. In the 800MHz frequency band, the terminal may select a 500KHz downlink channel or a 125KHz downlink channel for downlink communication.

Referring to fig. 7, a flowchart illustrating a third step of the method for a terminal to communicate with a server according to the present application is shown, which may specifically include the following steps:

step 501, the terminal receives a sixth message sent by the server through the first base station; the sixth message comprises third information;

in this embodiment of the application, the sixth message may be a Media Access Control (MAC) command. For example, the sixth message may be a burst slot channel command message (pingslotchannellind).

The sixth message may include third information, and the third information may indicate a manner of determining the downlink channel.

In one example, the third information may be a burst slot type information (PingslotType), and different values of the third information may indicate different downlink channel determination manners.

Step 502, the terminal determines a ninth downlink channel or a tenth downlink channel according to the third information; the ninth downlink channel is in a fourth downlink channel subset, the tenth downlink channel is in a fifth downlink channel subset, the fourth downlink channel subset and the fifth downlink channel subset are in a fourth downlink channel set, and the frequency width of the channel in the fourth downlink channel subset is greater than the frequency width of the channel in the fifth downlink channel subset;

in the 800MHz band, the fourth downlink channel subset may be a subset of 500KHz downlink channels in the 866-869MHz channel set, and the fifth downlink channel subset may be a subset of 125KHz downlink channels.

The terminal may determine, according to the third information in the sixth message sent by the server through the first base station, a ninth downlink channel with a larger frequency width or a tenth downlink channel with a smaller frequency width.

In the embodiment of the present application, step 502 may further include the following sub-steps:

in sub-step S21, if the third information is the first identifier, the terminal determines a ninth downlink channel in the fourth downlink channel subset;

in one example, if the third information is the first identifier, the terminal determines the downlink channel in the 125KHz channel subset using a calculation formula of the 125KHz channel. The second information may be burst slot type information (PingslotType), for example, the first identifier may be PingslotType ═ 0.

In substep S22, if the third information is the second identifier, the terminal determines a tenth downlink channel in the fifth downlink channel subset;

and if the third information is the second identifier, the terminal determines the downlink channel in the 500KHz channel subset by using a calculation formula of the 500KHz channel. For example, the second flag is PingslotType ═ 1.

In sub-step S23, if the third information is the third identifier, the terminal determines a ninth downlink channel or a tenth downlink channel in the fourth downlink channel set.

If the third information is the third identifier, the terminal may determine the downlink channel in the 125KHz and 500KHz channel subsets using a calculation formula of the mixed channel scheme. For example, the third identifier may be PingslotType 2.

Step 503, the terminal configures the ninth downlink channel or the tenth downlink channel as a downlink channel of a burst slot;

the terminal may configure the ninth downlink channel as a downlink channel of the burst slot, and receive data sent by the base station in the burst slot through the ninth downlink channel; or configuring the tenth downlink channel as the downlink channel of the pulse time slot, and receiving the data sent by the base station in the pulse time slot through the tenth downlink channel.

Step 504, the terminal sends a seventh message to the server through the second base station; the seventh message includes a feedback result of a downlink channel for the terminal configuration burst slot.

And after the terminal is configured with the downlink channel of the pulse time slot, the terminal can send a seventh message to the server through the second base station. The seventh message may also be a MAC command, and in one example the seventh message may be a burst slot channel configuration message (pingslotchannel conf)

The seventh message may include a feedback result of the downlink channel for the terminal-configured burst slot. For example, if the feedback result ACK is 1, it indicates that the burst slot channel configuration has failed, and if the feedback result ACK is 0, it indicates that the burst slot channel configuration has succeeded. Of course, other values may be used to represent the feedback result, which is not limited in the embodiment of the present application.

In this embodiment, the terminal may receive, by the first base station, a sixth message sent by the server, and determine, according to the sixth message, whether to select a ninth downlink channel with a larger frequency width or a tenth downlink channel with a smaller frequency width as the downlink channel. In the 800MHz frequency band, the terminal may use a 500KHz downlink channel or a 125KHz downlink channel as the downlink channel of the pulse timeslot for downlink communication.
