The audio-frequency information of harvester acquisition, the pictorial information of the image acquisition devices such as camera, the intelligence instruments such as water meter, ammeter
Yardage information of acquisition etc..
Currently, in order to obtain longer life cycle, NB-IoT terminals are only waken up at a fixed time, are kept for certain time
After, reenter sleep.In order to facilitate the business datum that device management server statistics, analysis NB-IoT terminals report, NB-
The time that the fixation of IoT terminals is waken up concentrates in a regular time section, this regular time section is known as wake-up period,
The time that NB-IoT terminals are waken up is known as wakeup time, and NB-IoT terminals are waken up is known as terminal to the period for reentering sleep
The time window waken up.
After NB-IoT terminals are waken up, NB-IoT terminals can send business datum to device management server.If waking up
The instruction of device management server transmission is received in the time window come, then NB-IoT terminals execute instruction, and in instruction execution
After reenter sleep.If not receiving the instruction of device management server transmission, NB- in the time window waken up
IoT terminals directly reenter sleep.After NB-IoT terminals enter sleep, NB-IoT terminals can not receiving device management service

302, when receiving the business datum of first terminal transmission, device management server judges belonging to first terminal
With the presence or absence of the terminal upgraded in Target cell.If being thened follow the steps there is no the terminal upgraded in Target cell
303 and 304；Otherwise, step 305 and 306 is executed.
In view of NB-IoT network bandwidths are relatively narrow, and the terminal quantity accessed in cell is more, the multiple terminals of parallel upgrade
The speed of download of single terminal can be caused slower, the time that single terminal downloads upgrade package is longer, and power consumption is larger.In order to reduce
The power consumption of terminal makes the completion upgrading that each terminal is as fast as possible, in embodiments of the present invention each cell same time
It can be there are one terminal downloads upgrade package.
When there is no the terminal that is upgrading, device management server can be according to receiving business datum in Target cell
Sequencing determine which current time upgrades and need the terminal that upgrades.If device management server receives multiple ends simultaneously
The business datum sent is held, then when device management server can determine current according to the sequencing of inter-process business datum
The terminal for carving upgrading, can also randomly choose the terminal that a terminal upgrades as current time, not to this embodiment of the present invention
It is construed as limiting.
In embodiments of the present invention, device management server judges in the Target cell belonging to first terminal with the presence or absence of just
It specifically can be implemented as in the terminal of upgrading：Judge in Target cell with the presence or absence of the terminal for downloading upgrade package；If target
There is no the terminals for downloading upgrade package in cell, it is determined that there is no the terminals upgraded in Target cell；If target
There is the terminal for downloading upgrade package in cell, it is determined that there is the terminal upgraded in Target cell.
303, device management server sends the instruction that Upgrades Now to first terminal.
Wherein, the instruction that Upgrades Now is used to indicate first terminal and Upgrades Now.It is understood that in the instruction that Upgrades Now
The download path of upgrade package is carried, terminal can download upgrade package according to the download path.
304, when receive device management server transmission Upgrade Now instruction when, first terminal download upgrade package.
When first terminal, which receives instruction, to be instructed to Upgrade Now, illustrate that there is no the ends upgraded in Target cell
End, first terminal can download upgrade package immediately.First terminal download upgrade package and carry out it is locally-installed and after restarting, to equipment
Manager sends updating result, including upgrades successfully, upgrading failure and failure cause, and the error message for recording escalation process is arrived
Daily record.
305, device management server sends delay upgrade command to first terminal.
Wherein, postpone in upgrade command comprising upgrading moment or delay time.Delay upgrade command is used to indicate first eventually
Upgrade package is downloaded in end since upgrading the moment, or is used to indicate first terminal and downloads upgrade package after waiting for delay time.
Delay time is that first terminal downloads the time needed to wait for before upgrade package.
306, when receiving the delay upgrade command of device management server transmission, first terminal refers to according to delay upgrading
The upgrading moment carried in order or delay time send business datum again to device management server.
When the instruction that first terminal receives is delay upgrade command, first terminal obtains the upgrading moment, and in the liter
The grade moment sends business datum again to device management server；Or first terminal obtains delay time, and it is to be delayed waiting
Business datum is sent again to device management server after time.
As shown in table 1, device management server is 8：When 00, while receiving what terminal A1, B1, C1 in cell 1 was sent
Business datum.Device management server determines that terminal A1 need not upgrade, and terminal B1 and C1 need to upgrade.If at this time in cell 1
There is no the terminal upgraded, then device management server selects a terminal to be upgraded from terminal B1 and terminal C1,
Such as terminal B1.Later, device management server sends the instruction that Upgrades Now to terminal B1, and sending delay upgrading to terminal C1 refers to
It enables.Device management server is 8：When 05, the business datum that terminal A2, B2, the C2 for needing to upgrade are sent is received.At this point, setting
Standby management server determines that terminal B1 is upgrading in cell 1, and device management server prolongs to terminal A2, B2, C2 transmission respectively
Slow upgrade command.
In view of NB-IoT networks have the characteristics that magnanimity connection, terminal quantity is more, in order to shorten batch upgrade terminal
Time, increase network utilization, avoid the terminal in cell to concentrate on the same period as possible and upgraded.Therefore, this hair
At the time of the upgrading moment in delay upgrade command in bright embodiment can be other than wake-up period, delay time can be big
In the time of wake-up period duration.So, in the time of non-wake-up period, also there is terminal to wake up and upgraded, shortened
The time of batch upgrade terminal improves the efficiency of batch upgrade terminal, meets in instruction period (such as 2 weeks) magnanimity terminal
The upgrade problem of (such as 1,000,000).
Since in the case where being not received by delay upgrade command, the terminal in cell 1 will not wake up in non-wake-up period
Come, therefore only have in non-wake-up period and receive the terminal of delay upgrade command and wake up at the upgrading moment, or prolongs having waited for
It wakes up after the slow time.Table 2 is on the basis of table 1, and device management server is by postponing the liter that upgrade command is terminal distribution
Grade timetable, terminal C1 is 9 in cell 1：10 wake up, and terminal A2 is 9：40 wake up, and terminal B2 is 10：10 wake up, and terminal C1 exists
9：10 to 9：30 upgradings, terminal A2 is 9：40 to 10：00 upgrading, terminal B2 is 10：10 to 10：30 upgradings.Equipment management service
The upgrading moment 9 carried in the delay upgrade command that device is sent to terminal C1：10, device management server is sent to terminal A2
The upgrading moment 9 carried in delay upgrade command：40, it takes in the delay upgrade command that device management server is sent to terminal B2
The upgrading moment 10 of band：10.After receiving delay upgrade command, terminal C1 is 9：10 send business number to device management server
According to terminal A2 is 9：40 send business datum to device management server, and terminal B2 is 10：10 send to device management server
Business datum.
Table 2 upgrades moment allocation table
In view of terminal downloads upgrade package needs certain time, in order to ensure each cell same time only to a terminal
Upgraded, device management server will also plan terminal upgrade finish time other than upgrading the moment for terminal distribution.When certain
A terminal, be to download the terminal of upgrade package as Gao You when the upgrading finish time of planning not yet completing upgrade package download
First grade redistributes the upgrading moment for subsequent terminal.As shown in table 2, device management server is the upgrading of terminal C1 planning
Finish time is 9：30, but 9：Terminal C1 is practical to 9 when 30：40, which just complete upgrade package, downloads, and 9：Terminal A2 has been when 30
Through reaching the standard grade, using terminal C1 as high priority is redistributed to terminal A2 the upgrading moment at this time, and terminal C1 is then normally downloaded and is risen
Grade packet is until complete.
In embodiments of the present invention, after sending delay upgrade command to first terminal, following steps can also be performed：
If during first terminal downloads upgrade package, the business datum of other-end transmission is received, then to other
Terminal sends delay upgrade command.
Influence in order to avoid terminal C1 upgrading delay to the terminal other than terminal A2, device management server is to terminal A2
Send delay upgrade command.
3 actual upgrade timetable of table
It should be noted that the purpose for the delay upgrade command that device management server is sent to first terminal is that notice is whole
The end next time waken up, the instruction can make universal command, be not limited to only do upgrading purposes.And upgrade when receiving delay
When instruction, the purpose of first terminal to device management server transmission business datum, which is annunciator management server, to be carried out
Communication.Therefore, when receiving delay upgrade command, first terminal sends business datum in addition to can be with to device management server
Can also be the information that empty information etc. is made an appointment for the information of the actual acquisitions such as audio, picture, yardage.
It is provided in an embodiment of the present invention upgrading narrowband internet-of-things terminal method, compared to the prior art in NB-IoT
In the time window that terminal is waken up, device management server carries out batch liter to NB-IoT terminals parallel according to own processing capabilities
Grade, the present invention is when, there is no when the terminal upgraded, instruction terminal Upgrades Now, when existing in Target cell in Target cell
When the terminal upgraded, instruction terminal upgrades at the specified upgrading moment.So, each Target cell same time
One terminal of upgrading improves the upgrading efficiency of terminal so as to shorten the time of each terminal downloads upgrade package.Therefore, this hair
Efficiency is lower when bright embodiment can solve the problems, such as to upgrade the NB-IoT terminals in cell.
The embodiment of the present invention provides also a kind of method of upgrading narrowband internet-of-things terminal, as shown in figure 4, this method flow has
