As shown in fig. 1, which is a schematic structural diagram of a power consumption control system of a narrowband internet of things terminal according to an embodiment of the present invention, the power consumption control system includes an MME (mobility management entity) 11 deployed in a cellular internet of things, a narrowband internet of things terminal 12, and an internet of things service platform 13. The narrowband internet of things terminal 12 and the internet of things service platform 13 are connected through a cellular internet of things, wherein the confirmation of the end-to-end service is to retransmit data by using a retransmission mechanism. The narrow-band internet of things terminal 12 comprises a communication module, a data processing module, a data acquisition module and a storage battery module. The communication module includes a receiving unit, a sending unit, a connection establishing unit, and the like, and is used for establishing communication with the MME11 and sending and receiving data. An eNB (base station), an MME (mobility management entity), an S-GW (serving gateway) and a P-GW (packet data gateway) are deployed in the cellular Internet of things. The service platform of the Internet of things is provided with a data receiving and sending unit, a data processing unit, a man-machine interaction unit and the like. The service platform of the Internet of things is accessed to the cellular Internet of things through the data receiving and sending unit, the man-machine interaction unit grasps the working states of all the equipment according to the map distribution condition and issues a parameter modification instruction to one or more selected narrow-band Internet of things terminals, and centralized remote management of all the networking narrow-band Internet of things terminals in the district is realized.
And the communication module in the narrow-band Internet of things terminal can establish radio resource bearing with the cell base station eNB of the cellular Internet of things. After the narrow-band Internet of things terminal accesses the network, the terminal is attached and registered to the network, and then the power saving mode of the terminal is initialized.
As shown in fig. 2, which is a schematic diagram of an implementation flow of a power consumption control method for a narrow-band internet of things terminal implemented by a network side, the method may include the following steps:
s21, receiving a power consumption control parameter negotiation request message sent by a narrow-band Internet of things terminal, wherein the power consumption control parameter negotiation request message carries a power consumption control parameter candidate value.
In specific implementation, the narrowband internet of things terminal is powered on and initialized, a communication module of the terminal initiates routing information such as an attachment request message, a network identification code ID and the like to the eNB to request attachment and complete network registration. The power consumption control parameter negotiation request message may be an attach request message, that is, the narrowband internet of things terminal may carry a power consumption control parameter candidate value in the attach request message, for example, a bit may be newly added in the attach request message to carry the power consumption control parameter candidate value, or a reserved bit in the attach request message may be used to carry the power consumption control parameter candidate value.
S22, judging whether the power consumption control parameter table stored in advance has the power consumption control parameter with higher priority, if so, executing the step S23, and if not, executing the step S24.
Wherein the power consumption control parameter may comprise an activity timer timing duration. The power consumption control parameters included in the power consumption control parameter table are determined for different network environment parameters, and as shown in table 1, it is a possible indication of the power consumption control parameter table:
TABLE 1
In specific implementation, for different network environment parameters (for example, RSRP, SINR, adhesion delay, and the like), different active timer timing durations may be preconfigured, after receiving a power consumption control parameter candidate value requested to be negotiated by a terminal side, the network side preferably determines whether a power consumption control parameter with a better priority exists according to a power consumption parameter control table stored in the network side, if not, determines that the power consumption control parameter candidate value requested to be negotiated by the terminal is a power consumption control parameter set value of the narrowband internet of things terminal, and if so, determines that the power consumption control parameter with a higher priority is a power consumption control parameter set value of the narrowband internet of things terminal.
The power consumption control parameter table stored at the network side has self-learning capability for optimal configuration of various applications. The network side has self-learning capability for setting the personalized power saving mode applied in each industry, and can preferably select the optimal local configuration for negotiation. The local configuration in the MME may perform the same parameter configuration for all the same class of service terminals in the coverage cell.
And S23, determining the power consumption control parameter with higher priority as the power consumption control parameter set value of the narrow-band Internet of things terminal, and executing the step S25.
And S24, determining the power consumption control parameter candidate value as a power consumption control parameter set value of the narrow-band Internet of things terminal.
And S25, returning a power consumption control parameter negotiation response message to the narrow-band Internet of things terminal, wherein the power consumption control parameter negotiation response message carries the determined power consumption control parameter set value.
In specific implementation, when data reported by the narrow-band Internet of things terminal is received, the activity timer is started; and if the data reported by the narrow-band Internet of things terminal is not received again after the timing duration of the activity timer is up, sending a dormancy indication to the narrow-band Internet of things terminal to indicate that the narrow-band Internet of things terminal enters a dormancy state. Specifically, the network side sends a message to the terminal after the timer expires to instruct the terminal to enter the sleep mode, the radio frequency of the terminal is turned off, and the terminal is powered off similarly, except that the communication module is still in the registration state in the network, and the PDN (public data network) connection does not need to be reattached or established when the terminal enters the idle state/connected state. That is, the module no longer listens to the CIOT (Cognitive IoT) network, and the CIOT network no longer knows whether the terminal is online. And when the terminal processor detects that the communication module enters a sleep mode, the terminal processor assigns values immediately to indicate the data acquisition unit to enter a low power consumption state.
In specific implementation, when data sent to the narrow-band internet of things terminal by an internet of things service platform is received, if the narrow-band internet of things terminal is judged to be in a dormant state, the data sent by the internet of things service platform is cached or the internet of things service platform is informed to cache the data to be sent; and when receiving the data reported by the narrow-band Internet of things terminal, sending the cached data to the narrow-band Internet of things terminal or informing the Internet of things service platform to send the cached data.
In specific implementation, when the narrowband internet of things terminal detects a preset trigger event, the narrowband internet of things terminal reestablishes RRC connection with the network side to report data to the network side. Specifically, when the terminal detects that a tilt angle change or a heartbeat cycle event occurs, the process of the data acquisition module is set to be in an executable state, the terminal data processing module is awakened, and the process is moved from the waiting queue to an executable message queue (red and black trees). And the data processing module assigns a communication module to establish RRC connection with the cellular Internet of things eNB. The communication module encapsulates the data in NAS (non access stratum) specific channels that have been ciphered and integrity protected to the cellular network element eNB. The eNB forwards the control plane service data to the MME, and if header compression is adopted, the MME needs to execute IP header decompression operation. The uplink data are finally forwarded to the data receiving and sending unit of the service platform of the internet of things through network elements of the cellular network, and are analyzed and transmitted to the human-computer interaction unit through the data processing unit, so that the remote management function is realized.
After data transmission is finished, the narrowband Internet of things terminal starts an activity timer after RRC connection is released, and after the activity timer is overtime, the terminal communication module enters a low-power-consumption sleep mode. The data processing module process marks itself as dormant, moves out of the executable Redwood tree, places it in a wait queue, and then calls schedule () to select and execute one of the other processes.
Correspondingly, an embodiment of the present invention further provides a narrowband internet of things terminal power consumption control method implemented by the narrowband internet of things terminal, as shown in fig. 3, the method may include the following steps:
and S31, sending a power consumption control parameter negotiation request message to a network side.
In specific implementation, after the narrowband internet of things terminal is powered on and initialized, a communication module in the terminal initiates routing information such as an attachment request message and a network identification code (ID) to an evolved node B (eNB) in the cellular internet of things, and the terminal requests attachment and completes network registration. A communication module of the terminal may negotiate with an MME on the network side through the attach request message carrying a power consumption control parameter candidate value (for example, may be a timing duration of a timing activity timer), and if there is no local configuration duration with a higher priority in the MME, determine to set the timing duration of the activity timer as the power consumption control parameter candidate value carried in the attach request initiated by the terminal. And if the local configuration time length with higher priority exists in the MME, determining the local configuration time length with higher priority of the MME as the timing time length of the activity timer.
And S32, receiving a power consumption control parameter negotiation response message returned by the network side.
The power consumption control parameter negotiation response message carries a power consumption control parameter set value determined by the network side.
And S33, determining power consumption control parameters according to the power consumption control parameter set values.
In specific implementation, after the time duration of the active timer is set, the communication module of the terminal may enter the sleep state according to any one of the following manners:
and the first mode is that the network side passively enters a dormant state according to the indication of the network side.
In this embodiment, there is a network side MME monitoring the active timer, and when the timer expires, the network side issues a message to the narrowband internet of things terminal to instruct the communication module of the terminal to enter a sleep state, specifically, the terminal radio frequency is turned off, and is similar to a power-off state, but is still in a registration state in the network. I.e. the terminal communication unit no longer listens to the network, nor does the network know whether the terminal is online or not. And when the processor of the terminal detects that the communication module enters a sleep mode, the processor assigns values immediately to indicate that the data acquisition module enters a low power consumption state.
And in the second mode, the communication module of the terminal actively enters a dormant state.
In this embodiment, after the data transmission with the network side is finished, the terminal releases the RRC connection with the eNB on the network side and starts the active timer, and when the timer expires, the communication module of the terminal enters the dormant state. And when the processor of the terminal detects that the communication module enters a sleep mode, the processor assigns values immediately to indicate that the data acquisition module enters a low power consumption state.
After the terminal enters the sleep state, the embodiment of the present invention performs uplink data transmission according to the flow shown in fig. 4:
s41, in the dormant state, when a preset trigger event is detected, the RRC connection is reestablished with the network side so as to report data to the network side.
Specifically, taking the narrow-band internet of things terminal as the manhole cover as an example, the preset trigger event may include a tilt angle change or a heartbeat cycle event, that is, when the narrow-band internet of things terminal detects that the tilt angle change or the heartbeat cycle event occurs, the process of the data acquisition module is set to an executable state, the terminal data processing module is awakened, and the process is moved from the waiting queue to an executable message queue (red and black tree). And the data processing module assigns a value to indicate the communication module to establish RRC connection with the cellular Internet of things eNB.
And S42, the communication module encapsulates the data in an NAS specific channel which is protected by encryption and integrity and transmits the NAS specific channel to a cellular network element eNB.
And S43, the eNB forwards the control plane service data to the MME.
In specific implementation, if header compression is adopted, the MME needs to perform IP header decompression. The uplink data is finally forwarded to the service management platform data receiving and sending unit through network elements of the cellular network, and is analyzed and transmitted to the man-machine interaction unit through the data processing unit, so that the remote management function is realized.
And S44, the data transmission is finished, the active timer is started by the narrow-band Internet of things terminal after the RRC connection is released, and the communication module of the terminal enters a low-power-consumption dormant mode state after the timer is overtime.
S45, the data processing module process marks the data processing module process into a dormant state, moves the data processing module process out of the executable red and black tree, puts the data processing module process into a waiting queue, and then calls schedule () to select and execute one other process.
After the narrowband internet of things terminal enters the sleep state, downlink data may be sent to the narrowband internet of things terminal according to the flow shown in fig. 5:
and S51, the service platform of the Internet of things sends data to be sent to the cellular Internet of things.
In this step, when an event that service parameters are modified such as calibrating an inclination angle, adjusting a heartbeat data period, setting an angle alarm threshold value and the like occurs, a human-computer interaction unit in the service platform of the internet of things encapsulates data through a data processing unit and then sends the data to a data receiving and sending unit, the data receiving and sending unit sends the data to an eNB in the cellular internet of things, and the eNB sends the received data to an MME.
S52, the MME informs the service platform of the Internet of things to cache the data to be sent.
In this step, when receiving data sent by the service platform of the internet of things to the narrowband internet of things terminal, if the MME judges that the narrowband internet of things terminal is in a dormant state, because the terminal is in the dormant state, the terminal is in a radio frequency off state, and the MME instructs the S-GW not to try downlink data delivery any more, and notifies the service platform of the internet of things that the data to be sent will be cached in the data transceiving unit, or the MME caches the data sent by the service platform of the internet of things in other cellular network elements of the internet of things, and the MME does not initiate paging to the UE.
And S53, when the data reported by the narrow-band Internet of things terminal is received, sending the cached data to the narrow-band Internet of things terminal or informing the Internet of things service platform to send the cached data.
In this step, when a trigger event or a heartbeat cycle event occurs at the terminal, the terminal communication module is awakened and starts the radio frequency function to report data to the network side, and after detecting that the terminal is activated, the MME sends the cached data to the narrowband internet of things terminal or notifies the internet of things service platform to send the cached data, so that the downlink cached data is transmitted to the communication module of the terminal.
And S54, the data transmission is finished, the active timer is started by the narrow-band Internet of things terminal after the RRC connection is released, and the communication module of the terminal enters a low-power-consumption dormant state after the timer is overtime.
And S55, after the terminal data processing module receives the instruction and executes the response operation, the terminal data processing module enters a low power consumption state.
In the embodiment of the invention, the narrowband Internet of things terminal carries the power consumption control parameter candidate value (for example, the duration of an active timer) and negotiates with a core network MME through a communication module attachment request message, if the MME does not have locally configured duration with higher priority, that is, the duration of the active timer is set as the current negotiation value, so that the high-power-consumption service time of the whole terminal redundancy is accurately reduced, and meanwhile, the switching of the terminal dormant state cannot cause unreliable cellular communication connection.
According to the power consumption control method of the narrow-band Internet of things terminal, provided by the embodiment of the invention, a terminal dormancy mechanism is designed according to the difference between the wireless coverage and the signal-noise interference environment of the narrow-band Internet of things terminal.
Based on the same inventive concept, the embodiments of the present invention also provide a narrowband internet of things terminal power consumption control device implemented by a network side and a terminal side, respectively, and because the principles of the device and the device for solving the problems are similar to the narrowband internet of things terminal power consumption control method, the implementation of the device can refer to the implementation of the method, and repeated details are not repeated.
As shown in fig. 6, a schematic structural diagram of a narrowband internet of things terminal power consumption control device implemented on a network side includes:
the receiving unit 61 is configured to receive a power consumption control parameter negotiation request message sent by a narrowband internet of things terminal, where the power consumption control parameter negotiation request message carries a power consumption control parameter candidate value;
