Detailed Description
As mentioned above, the existing network architecture of the narrowband internet of things can only show the advantages in the areas where terminal distribution is concentrated, and for the areas where the distance is far away and the trace is rare, such as mountain areas, grassland forests, oceans, etc., the conventional communication network cannot or is difficult to deploy, for example, more base stations or relays need to be built along the way, and meanwhile, the base stations have no so many terminal devices in the coverage area, so that the waste of resources and cost is caused.
The inventor of the invention finds that in the prior art, the current main internet of things communication mode aiming at the remote non-coverage area is a signal information receiving and transmitting mode or a manual information acquisition mode based on a communication satellite. However, satellite communication is high in comprehensive cost, internet of things equipment for livestock or meteorological observation is difficult to deploy and apply, manual information acquisition is high in error rate, and missing or mistaking is easy to occur.
Specifically, the satellite communication terminal has higher cost, the single communication cost is high, enterprises or individuals cannot bear the satellite communication terminal for a long time, the satellite communication terminal and network equipment are far beyond NBIOT terminals, the satellite communication bandwidth is limited, and simultaneous communication of a large number of Internet of things equipment in a unit area is difficult to bear.
In the embodiment of the invention, the terminal equipment is controlled to enter the active state from the dormant state at the preset awakening time, and then enters the dormant state from the active state after the service data are uploaded to the mobile base station, so that the terminal equipment is in the PSM dormant state most of the time, the power consumption of the terminal equipment is effectively reduced, and the operation cost is reduced.
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, fig. 1 is a flowchart of a communication method of the internet of things in an embodiment of the present invention. The internet of things communication method may include steps S11 to S13:
step S11: controlling the terminal equipment to enter an activated state from a dormant state at a preset wake-up time;
step S12: establishing network connection between the terminal equipment and a mobile base station, and controlling the terminal equipment to upload service data to the mobile base station;
step S13: and controlling the terminal equipment to enter the dormant state from the activated state.
The mobile base station operates on a preset route, and the terminal equipment is located in a preset range around the preset route.
In the embodiment of the present invention, the cyclic prefix extension generating method provided in the steps S11 to S13 may be performed by the ue. Specifically, the steps S11 to S13 may be performed by a baseband chip in the ue, or a chip module including the baseband chip in the ue.
In the implementation of step S11, the terminal device is controlled to enter the active state from the sleep state at the preset wake-up time according to the preset wake-up time, so as to wake up the terminal device.
Further, before the terminal equipment is controlled to enter the active state from the dormant state at the preset wake-up time, the method further comprises the step of determining the preset wake-up time of the terminal equipment.
It should be noted that, in the initial stage, an 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 equipment can also be determined according to specific conditions.
In a specific implementation, the terminal device may be divided into regions according to the operation line of the mobile base station.
The mobile base station can have the characteristics of small volume, small energy consumption, small power and the like, and can be a small base station supported by conventional technology, such as a mobile device for realizing a mobile function.
Further, the mobile device can be determined according to the application scene, for example, in grasslands, deserts or forest areas, and flying hot air balloon deployment mobile base stations can be selected; in the ocean or large lake area, a ship with periodic cruising can be selected to deploy a mobile base station, etc.
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 operate in the arrow direction on a preset route as shown by solid lines, and the terminal device is located within a preset range around the preset route.
It can be appreciated that when the mobile base station moves to a position closest to the mobile base station, the terminal device needs to be located in 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, and specifically, the completion of the movement of a whole closed loop may be regarded as the completion of one operation.
Further, before the terminal device is controlled to enter the active state from the sleep state at the preset wake-up time, the method may further include: dividing each terminal device into areas, wherein each area comprises one or more terminal devices; and determining preset wake-up time of the terminal equipment contained in each area.
Specifically, as shown in fig. 2, a plurality of areas are divided by using a dotted line, and each area includes one or more terminal devices for an area including the terminal devices.
When the mobile base station moves on a preset route, the mobile base station sequentially passes through each area, and on the operation route of each area, the signal range can be covered to the terminal equipment in the area.
Still further, the step of performing region division on each terminal device may include: determining an upper limit of the area according to the coverage area of the mobile base station; wherein, the smaller the coverage area of the mobile base station, the smaller the upper limit of the area.
Taking a conventional NBIOT base station as an example, the coverage area of the conventional NBIOT base station is 10Km, the area of each area can be determined according to the coverage area of the NBIOT base station, for example, when the NBIOT base station is located in the central position of the area, the coverage area of the NBIOT base station can completely cover the area, and at the moment, all terminal devices in the area can be awakened only by setting a single preset awakening time.
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
Figure BDA0002937300250000071
In the specific embodiment shown in table 1, between the entering time when the mobile base station enters the area and the exiting time when the mobile base station exits the area, the intermediate time may be set to be a preset wake-up time to wake up all the terminal devices in the current area.
Further, the step of determining the preset wake-up time of the terminal device included in each area may include: for each area, determining the entering time of the mobile base station entering the area and the leaving time of the mobile base station leaving the area; and determining the preset wake-up time of the terminal equipment contained in the area according to one or more time points between the entering time and the leaving time.
Taking the lower left area in fig. 2 as an example, the entering time of the mobile base station entering the area is Ta, the leaving time of the mobile base station leaving the area is Tb, and the preset wake-up time of the terminal device a and the terminal device B may be determined according to one or more time points between Ta and Tb.
In the embodiment of the invention, through dividing the areas of the terminal equipment, each area contains one or more terminal equipment, when the base station moves to a certain area, the terminal equipment is controlled to wake up the access network according to the operation plan at regular time and upload service data to finish the work, and compared with satellite communication, the deployment cost is effectively reduced.
Further, determining the wake-up frequency of the preset wake-up time according to the mobile state of the terminal equipment; for a terminal device in a mobile state, determining the preset awakening time by adopting a first awakening frequency; for terminal equipment in a non-mobile state, determining the preset awakening time by adopting a second awakening frequency; the first wake-up frequency is greater than the second wake-up frequency.
Specifically, the mobile state of the terminal device may have a correlation with the type of the service data, when the service data to be collected is mobile terminal data deployed in a non-fixed manner, such as livestock information, the terminal device may need to be set on animals such as cattle, sheep, etc., and the terminal device may be regarded as the mobile state, and it may be understood that the mobile speed of the mobile terminal device deployed in a non-fixed manner is often low. On the other hand, when the service data to be collected is weather-observing information, the terminal device may need to be set at a fixed position, and the terminal device may be regarded as a non-moving state.
In the embodiment of the invention, for the terminal equipment in the mobile state, the higher awakening frequency is adopted, and the terminal equipment in the mobile state can be awakened and the service data is uploaded by adopting the higher awakening frequency, so that the condition that the terminal equipment in the mobile state leaks service data due to movement or cross-region is effectively avoided, and the fault tolerance can be enhanced by improving the frequency of active awakening.
Further, the step of determining the preset wake-up time of the terminal device included in each area may include: for an area containing one or more terminal devices, all terminal devices in the area adopt the same preset wake-up time.
As in fig. 2, one or more time points may be determined between Ta and Tb, and serve as preset wake-up times of terminal device a and terminal device B, and the preset wake-up times of terminal device a and terminal device B are the same.
In the embodiment of the invention, for the area containing a plurality of terminal devices, each terminal device in the area adopts the same preset wake-up time, so that the plurality of terminal devices can be waken up uniformly in each area, and the complexity is reduced.
Further, the step of determining the preset wake-up time of the terminal device included in each area may include: for an area containing a plurality of terminal devices, each terminal device in the area adopts respective preset wake-up time, and the preset wake-up time between different terminal devices is the same or different.
As shown in fig. 2, two time points may be determined between Ta and Tb and used as preset wake-up times of the terminal device a and the terminal device B, respectively, where the preset wake-up times of the terminal device a and the terminal device B may be the same or different.
In the embodiment of the invention, for the area containing a plurality of terminal devices, each terminal device in the area adopts respective preset wake-up time, the preset wake-up time between different terminal devices is the same or different, and peak-shifting wake-up can be performed by setting the wake-up time difference, so that interference and network blocking are effectively reduced.
Furthermore, the more the terminal equipment is close to the entering position of the mobile base station into the area, the earlier the preset wake-up time of the terminal equipment is, the more the terminal equipment is close to the exiting position of the mobile base station from the area, and the later the preset wake-up time of the terminal equipment is, so that in the process of setting the wake-up time difference and carrying out peak-shifting wake-up, the terminal equipment is more beneficial to being awakened under the condition of being covered by the mobile base station.
With continued reference to fig. 1, in the 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 a network connection between the terminal device and the mobile base station may comprise: and controlling the terminal equipment to perform network searching by only adopting the frequency point of the mobile base station so as to establish network connection between the terminal equipment and the mobile base station.
It should be noted that, in the embodiment of the present invention, if the mobile base station is fixed, the number of band (band) frequency points (also called frequency points) where the terminal device establishes a network connection with the mobile base station is limited, and if the terminal device is set to search only the limited number of frequency points, the required time can be effectively reduced.
In the embodiment of the invention, the terminal equipment is controlled to perform network searching only by adopting the frequency points of the mobile base station so as to establish network connection between the terminal equipment and the mobile base station.
Further, the communication method of the internet of things may further include: and controlling the terminal equipment to receive the updated preset wakeup time from the mobile base station, and uploading the next service data by adopting the updated preset wakeup time.
In a specific implementation, if the running schedule and the timetable of the mobile base station are expected to change, the mobile base station can send updated preset wake-up time in the running process of the last round of mobile base station, and further, the terminal equipment is awakened by the updated preset wake-up time in the running process of the next round of mobile base station, and the service data is uploaded. Wherein, the movement of completing a whole closed loop can be used as the completion of a round of movement of the base station.
In the embodiment of the invention, the terminal equipment is controlled to receive the updated preset wakeup time from the mobile base station, and the next service data uploading is performed by adopting the updated preset wakeup time, so that the terminal equipment can be informed of updating when the operation plan and the schedule of the mobile base station change and the last service data uploading is performed, thereby being beneficial to reducing the information quantity sent by the mobile base station to the terminal equipment, namely reducing signaling overhead and occupying less storage space.
In the embodiment of the invention, the terminal equipment is controlled to enter the active state from the dormant state at the preset awakening time, and then enters the dormant state from the active state after the service data are uploaded to the mobile base station, so that the terminal equipment is in the PSM dormant state most of the time, the power consumption of the terminal equipment is effectively reduced, and the operation cost is reduced.
In the embodiment of the invention, another communication method of the internet of things is also provided, which comprises the following steps: receiving service data, wherein the service data is uploaded by the terminal equipment under control after establishing network connection between the terminal equipment and a mobile base station; before establishing network connection between the terminal equipment and the mobile base station, the terminal equipment enters an active state from a dormant state at a preset wake-up time; after the terminal equipment is controlled to upload service data, the terminal equipment enters an activated state from a dormant state at a preset wake-up time; the mobile base station operates on a preset route, and the terminal equipment is located in a preset range around the preset route.
