Abstract

The present disclosure provides system and methods for allocating the schedule period among multiple channels. The method includes receiving a first signal from a first channel and receiving a second signal from a second channel. The first signal includes a first communication request and the second signal includes a second communication request. The method includes determining a first priority degree corresponding to the first communication request and a second priority degree corresponding to the second communication request, estimating a first data flow in the first signal over a schedule period and a second data flow in the second signal over the schedule period, and allocating the schedule period to the first channel and the second channel based on the first priority degree, the second priority degree, the estimated first data flow, and the estimated second data flow.

First claim

What is claimed is:

1 . A method, comprising:
receiving a first signal from a first device through a first channel of an IoT device, the first signal comprising a first communication request; receiving a second signal from a second device through a second channel of the IoT device, the second signal comprising a second communication request; determining a first priority degree corresponding to the first communication request and a second priority degree corresponding to the second communication request; estimating a first data flow in the first signal over a schedule period and a second data flow in the second signal over the schedule period; allocating the schedule period to the first channel and the second channel based on the first priority degree, the second priority degree, the estimated first data flow, and the estimated second data flow; and receiving data from or transmitting data to the first channel and the second channel based on the allocation of the schedule period, wherein the first priority degree is higher than the second priority degree, and the allocating of the schedule period to the first channel and the second channel comprises:
allocating at least a portion of the schedule period to the first channel;
determining whether a remaining time period of the schedule period is greater than a predetermined threshold after allocating the at least a portion of the schedule period to the first channel; and
in response to determining that the remaining time period of the schedule period is greater than the predetermined threshold,
allocating the remaining time period to the first channel and the second channel based on the estimated first data flow and the estimated second data flow.

2 . The method of claim 1 , wherein a ratio between a first duration over the remaining time period allocated to the first channel and a second duration over the remaining time period allocated to the second channel is proportional to a ratio between the estimated first data flow and the estimated second data flow or a ratio between an estimated first count of data packets through the first channel and an estimated second count of data packets through the second channel.

3 . The method of claim 1 , wherein in response to determining that a remaining time period of the schedule period is not greater than the predetermined threshold, the method further comprises:
allocating the remaining time period to the first channel.

4 . The method of claim 1 , wherein the schedule period is a time period between two channel allocation reference time points.

5 . The method of claim 4 , wherein the two channel allocation reference time points each is either a Target Beacon Transmission Time (TBTT) of the first signal or a TBTT of the second signal.

6 . The method of claim 1 , wherein
the first data flow in the first signal over the schedule period is estimated based on a size of data received and transmitted in a preceding schedule period through the first channel and a size of data ready to be transmitted in the schedule period through the first channel, and the second data flow in the second signal over the schedule period is estimated based on a size of data received and transmitted in the preceding schedule period through the second channel and a size of data ready to be transmitted in the schedule period through the second channel.

7 . The method of claim 1 , wherein the determining of the first priority degree corresponding to the first communication request and the second priority degree corresponding to the second communication request comprises:
identifying a first communication task in the first communication request and a second communication task in the second communication request; and determining the first priority degree and the second priority degree based on types of the first communication task and the second communication task.

8 . The method of claim 7 , wherein
the types of the first communication task and the second communication task include a management of connection, data of connection, or data transmission, and a priority degree corresponding to the management of connection is higher than a priority degree corresponding to the data of connection and the priority degree corresponding to the data of connection is higher than a priority degree corresponding to the data transmission.

9 . An IoT device comprising:
a processor; and a memory storing instructions that, when executed by the processor, configure the IoT device to:
receive a first signal from a first device through a first channel of the IoT device, the first signal comprising a first communication request;
receive a second signal from a second device through a second channel of the IoT device, the second signal comprising a second communication request;
determine a first priority degree corresponding to the first communication request and a second priority degree corresponding to the second communication request;
estimate a first data flow in the first signal over a schedule period and a second data flow in the second signal over the schedule period;
allocate the schedule period to the first channel and the second channel based on the first priority degree, the second priority degree, the estimated first data flow, and the estimated second data flow; and
receive data from or transmit data to the first channel and the second channel based on the allocation of the schedule period,
wherein the first data flow in the first signal over the schedule period is estimated based on a size of data received and transmitted in a preceding schedule period through the first channel and a size of data ready to be transmitted in the schedule period through the first channel,
wherein the second data flow in the second signal over the schedule period is estimated based on a size of data received and transmitted in the preceding schedule period through the second channel and a size of data ready to be transmitted in the schedule period through the second channel.

10 . The IoT device of claim 9 , wherein the first priority degree is higher than the second priority degree, and the communication schedule comprises:
allocate at least a portion of the schedule period to the first channel.

11 . The IoT device of claim 10 , wherein the instructions further configure the IoT device to:
determine whether a remaining time period of the schedule period is greater than a predetermined threshold after allocating the at least a portion of the schedule period to the first channel; and in response to determining that the remaining time period of the schedule period is greater than the predetermined threshold, allocate the remaining time period to the first channel and the second channel based on the estimated first data flow and the estimated second data flow.

12 . The IoT device of claim 11 , wherein a ratio between time over the remaining time period allocated to the first channel and time over the remaining time period allocated to the second channel is proportional to a ratio between the estimated first data flow and the estimated second data flow or a ratio between an estimated first count of data packets through the first channel and an estimated second count of data packets through the second channel.

13 . The IoT device of claim 11 , wherein in response to determining that a remaining time period of the schedule period is not greater than the predetermined threshold, the instructions further configure the IoT device to:
allocate the remaining time period to the first channel.

14 . The IoT device of claim 9 , wherein the schedule period
