Detailed ways

As mentioned above, the existing NB-IoT network architecture can only show its advantages in areas where terminals are more concentrated. For remote and inaccessible areas, such as plateau mountains, grasslands, forests, oceans, etc., conventional communication networks cannot or are difficult to For deployment, for example, more base stations or relays need to be built along the way, and at the same time, because the base station does not have so many terminal devices in the coverage area, it results in a waste of resources and costs.

The inventors of the present invention have found through research that, in the prior art, the current main communication mode of the Internet of Things for remote non-coverage areas is a communication satellite-based signal sending and receiving information method or an artificial information collection method. However, the overall cost of using satellite communication is high, and IoT devices for animal husbandry or meteorological observation are difficult to deploy and apply. Manual information collection has a high error rate and is prone to missed or mis-collected data.

Specifically, the cost of satellite communication terminals is high, and the cost of single communication is also high, which is difficult for enterprises or individuals to bear for a long time, far exceeding NBIOT terminals and network equipment, and the bandwidth of satellite communication is limited, which makes it difficult to undertake simultaneous communication of a large number of IoT devices per unit area. .

In the embodiment of the present invention, by controlling the terminal device to enter the active state from the dormant state at the preset wake-up time, and to enter the dormant state from the active state after uploading service data to the mobile base station, the terminal device can be made to spend most of the time in the active state. All are in the PSM sleep state, which effectively reduces the power consumption of the terminal equipment and reduces the operating cost.

In order to make the above objects, features and beneficial effects of the present invention more clearly understood, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to FIG. 1 , FIG. 1 is a flowchart of an IoT communication method in an embodiment of the present invention. The IoT communication method may include steps S11 to S13:

Step S11: control the terminal device to enter the active state from the dormant state at the preset wake-up time;

Step S12: Establish a network connection between the terminal device and the mobile base station, and control the terminal device to upload service data to the mobile base station;

Step S13: Control the terminal device to enter the sleep state from the active state.

It can be understood that, in a specific implementation, the method can be implemented in the form of a software program, and the software program runs in a processor integrated inside a chip or a chip module.

Wherein, the mobile base station operates on a preset route, and the terminal device is located within a preset range around the preset route.

In this embodiment of the present invention, the method for generating a cyclic prefix extension provided by the foregoing steps S11 to S13 may be executed by the user equipment. Specifically, the above steps S11 to S13 may be performed by a baseband chip in the user equipment, or performed by a chip module including a baseband chip in the user equipment.

In the specific implementation of step S11, according to the preset wake-up time, the terminal device is controlled to enter the active state from the sleep state at the preset wake-up time, so as to wake up the terminal device.

Further, before controlling the terminal device to enter the active state from the sleep state at the preset wake-up time, the method further includes the step of determining the preset wake-up time of the terminal device.

It should be noted that, in the initial stage, the initial preset wake-up time may be stored in the terminal device, and then updated on the basis of the initial preset wake-up time; the preset wake-up time of the terminal device may also be determined according to specific conditions.

In a specific implementation, the terminal equipment can be divided into areas according to the operating line of the mobile base station.

Wherein, the mobile base station may have the characteristics of small size, low energy consumption, low power, etc., and may be a small base station supported by conventional technology, such as being set on a mobile device to realize the mobile function.

Further, the mobile device can be determined according to the application scenario. For example, in grasslands, deserts, or forests, you can choose to fly hot air balloons to deploy mobile base stations; in oceans or large lake areas, you can choose regular cruise ships to deploy mobile base stations.

Referring to FIG. 2, FIG. 2 is a schematic diagram of location deployment of a terminal device and a mobile base station in an embodiment of the present invention.

As shown in FIG. 2 , the mobile base station may run in the direction of the arrow on the preset route shown by the solid line, and the terminal device is located within a preset range around the preset route.

It can be understood that when the mobile base station moves to the closest position, the terminal device needs to be located within the signal coverage of the mobile base station to meet the requirement of uploading service data.

Further, the operation route of the mobile base station may be a closed-loop route, and the operation time period is a preset period duration. Specifically, the completion of a whole closed-loop movement may be regarded as a completion of one operation.

Further, before controlling the terminal device to enter the active state from the dormant state at the preset wake-up time, the method may further include: dividing each terminal device into regions, each region including one or more terminal devices; determining that each region includes The preset wake-up time of the terminal device.

Specifically, as shown in FIG. 2, a dashed line is used to divide multiple areas, and for an area containing terminal devices, each area contains one or more terminal devices.

When the mobile base station moves on the preset route, it passes through each area in turn, and on the running route of each area, the signal range can cover the terminal equipment in the area.

Further, the step of dividing each terminal equipment into an area may include: determining the upper limit of the area of the area according to the coverage of the mobile base station; wherein, the smaller the coverage of the mobile base station, the upper limit of the area of the area. smaller.

Taking a conventional NBIOT base station as an example, its coverage is 10Km, and the area of each area can be determined according to the coverage of the NBIOT base station. For example, when the NBIOT base station is located in the center of the area, its coverage can completely cover the area. Only a single preset wake-up time can be set to wake up all terminal devices in the area.

Referring to Table 1, Table 1 is a preset wake-up schedule of a terminal device in an embodiment of the present invention.

Table 1

In the specific embodiment shown in Table 1, between the entry time when the mobile base station enters the area and the departure time when the mobile base station leaves the area, an intermediate time can be set as a preset wake-up time to wake up all terminal devices in the current area. .

Further, the step of determining the preset wake-up time of the terminal equipment included in each area may include: for each area, determining the entry time of the mobile base station entering the area and the departure time of leaving the area; according to the entry time One or more time points between the time of leaving and the time of leaving are used to determine the preset wake-up time of the terminal equipment included in the area.

Taking the lower left area in FIG. 2 as an example, the entry time of the mobile base station entering this area is Ta, and the departure time of leaving this area is Tb, and the terminal equipment can be determined according to one or more time points between Ta and Tb. The preset wake-up time of A and terminal device B.

In the embodiment of the present invention, by dividing each terminal device into areas, each area contains one or more terminal devices, and when the base station moves to a certain area, the terminal device can be controlled to wake up the access network regularly according to the operation plan and upload the The business data completes the work, which effectively reduces the deployment cost compared with satellite communication.

Further, the wake-up frequency of the preset wake-up time is determined according to the mobile state of the terminal device; wherein, for a terminal device in a mobile state, the preset wake-up time is determined by using a first wake-up frequency; for a terminal in a non-mobile state The device uses a second wake-up frequency to determine the preset wake-up time; the first wake-up frequency is greater than the second wake-up frequency.

Specifically, the movement state of the terminal device may be related to the type of the service data. When the service data to be collected is terminal data of non-fixed deployment and movement, such as animal husbandry information, the terminal device may need to be set in the cattle , sheep and other animals, the terminal device can be regarded as a moving state. It is understandable that for a terminal device that is not fixedly deployed and moved, its moving speed is often low. On the other hand, when the business data to be collected is meteorological observation information, the terminal device may need to be set in a fixed position, and the terminal device may be regarded as a non-mobile state.

In the embodiment of the present invention, for a terminal device in a mobile state, a higher wake-up frequency can be used, and a terminal device in a mobile state can be woken up with a higher wake-up frequency and upload service data, thereby effectively avoiding the terminal device in a mobile state. If the device misses sending service data due to movement or cross-region, the fault tolerance can be enhanced by increasing the frequency of active wake-up.

Further, the step of determining the preset wake-up time of the terminal equipment included in each area may include: for an area containing one or more terminal devices, all terminal devices in the area use the same preset wake-up time.

As shown in FIG. 2 , one or more time points can be determined between Ta and Tb as the preset wake-up time of terminal device A and terminal device B, and the preset wake-up time of terminal device A and terminal device B are the same.

In the embodiment of the present invention, for an area containing multiple terminal devices, each terminal device in the area adopts the same preset wake-up time, and can wake up multiple terminal devices in each area uniformly, thereby reducing the complexity.

Further, the step of determining the preset wake-up time of the terminal equipment included in each area may include: for an area containing multiple terminal devices, each terminal device in the area adopts its own preset wake-up time, and between different terminal devices. The preset wake-up time is the same or different.

As shown in FIG. 2 , two time points can be determined between Ta and Tb as the preset wake-up time of terminal device A and terminal device B, respectively, and the preset wake-up time of terminal device A and terminal device B can be the same, and the can be different.

In this embodiment of the present invention, for an area containing multiple terminal devices, each terminal device in the area adopts its own preset wake-up time, and the preset wake-up time between different terminal devices is the same or different. Time difference, staggered wake-up, effectively reducing interference and network congestion.

Further, it can be set that the closer the terminal device is to the entry position of the mobile base station entering the area, the earlier the preset wake-up time of the terminal device, and the closer the terminal device is to the departure position of the mobile base station leaving the area, the preset wake-up time of the terminal device. The later the time is, in the process of setting the wake-up time difference and performing peak-staggered wake-up, it is more beneficial to wake up each terminal device under the coverage of the mobile base station.

1, in the specific implementation of step S12, a network connection between the terminal device and the mobile base station is established, and the terminal device is controlled to upload service data to the mobile base station.

Further, the step of establishing the network connection between the terminal device and the mobile base station may include: controlling the terminal device to perform network search using only the frequency points of the mobile base station, so as to establish the connection between the terminal device and the mobile base station. network connection.

It should be pointed out that, in the embodiment of the present invention, the mobile base station is fixed, and the number of band frequency points (also called frequency points) for establishing a network connection between the terminal equipment and the mobile base station is limited. Searching for the limited number of frequency points can effectively reduce the required time.

In the embodiment of the present invention, the terminal equipment is controlled to only use the frequency points of the mobile base station to perform network search, so as to establish a network connection between the terminal equipment and the mobile base station. Since a single base station is used to deploy coverage, the terminal can be simplified. The number of bands supported, which helps to speed up network search times.

Further, the IoT communication method may further include: controlling the terminal device to receive an updated preset wake-up time from the mobile base station, and use the updated preset wake-up time to upload the next service data.

In the specific implementation, if the operation plan and timetable of the mobile base station are expected to change, during the last round of operation of the mobile base station, the updated preset wake-up time can be sent through the mobile base station, and then in the next round of operation of the mobile base station. , using the updated preset wake-up time to wake up the terminal device and upload service data. Among them, the completion of a whole closed-loop movement can be regarded as the completion of one round of mobile base station operation.

In the embodiment of the present invention, controlling the terminal device to receive the updated preset wake-up time from the mobile base station, and using the updated preset wake-up time to perform the next service data upload, can be performed during the operation of the mobile base station. When the plan and timetable change, the terminal equipment is notified of the update when the last round of service data is uploaded, which helps to reduce the amount of information sent by the mobile base station to the terminal equipment, that is, reduces signaling overhead and occupies less storage space.
