The processor 151 is configured to process digital signals and execute programs in accordance with exemplary embodiments of the present invention, and may access data and software modules recorded by the base station 150. The functions of the processor 151 may be implemented by using a Programmable Unit such as a Central Processing Unit (CPU), a microprocessor, a microcontroller, a Digital Signal Processor (DSP) chip, a Field Programmable Gate Array (FPGA), or the like. The functions of the processor 151 may also be implemented by a separate electronic device or Integrated Circuit (IC), and the operations of the processor 151 may also be implemented by software.

In addition, the base station 150 can transmit or receive data with the remote host 110 via a backhaul (interface) and the network 130.
Fig. 3 is a block diagram of components of a user equipment 170 in accordance with an embodiment of the present invention. Referring to fig. 3, the user equipment 170 includes, but is not limited to, a processor 171 (i.e., a host system) and a communication transceiver 173. It is noted that the embodiments and operations of the processor 171 and the communication transceiver 173 can refer to the detailed description of the processor 151 and the communication transceiver 153 in fig. 2, and therefore will not be described repeatedly.
To facilitate understanding of the operation flow of the embodiment of the present invention, the operation flow of the communication system 1 in the embodiment of the present invention will be described in detail below with reference to various embodiments.
Fig. 4 is a flowchart of a remote control method according to an embodiment of the invention. Referring to fig. 4, the remote host 110 transmits configuration commands to the base station 150 via the network 130 (via the backhaul) (step S410). The configuration command is associated with setting or changing the power saving configuration of the UE 170. Stated differently, embodiments of the present invention are directed to the remote host 110 actively initiating settings or other controls for the user equipment 170. The power saving configuration is related to wake-up connection of remote control, switching power saving mode, adjusting sleep or listening time of power saving mode and/or other power supply and power consumption related configurations. It is noted that the type and/or content of the power saving configuration may vary according to the specification of the communication transceiver 173 of the ue 170, and will be described in detail later. It is noted that, to save power, the processor 171 of the ue 170 is in a sleep mode (e.g., sleep, deep sleep, hibernate, power saving, or other modes with lower power consumption than the normal mode).
After the communication transceiver 153 of the base station 150 receives the configuration command, the processor 151 configures the broadcast message transmitted by the communication transceiver 153 according to the configuration command (step S420) (i.e., the remote host 110 triggers processing of the broadcast message). In particular, the configuration instructions may specify a requirement object (i.e., one or more ues 170) for control of a particular ue or ues 170. The broadcast message may include identification information of the object requested by the configuration command (e.g., Media Access Control (MAC) address, device identification code, user identification code, or other unique identification information). In addition, the broadcast message may further include a security key for decrypting information related to subsequent resource access operations, thereby informing the ue 170 of the source and the destination (i.e., which bs 150/remote host 110 transmitted and to which bs 150 the response should be transmitted). The communication transceiver 153 then transmits broadcast messages to the ues 170 within its service coverage.
The communication transceiver 173 of the ue 170 receives the broadcast message from the base station 150 via the corresponding cellular internet of things network (step S430). This Broadcast message is transmitted, for example, via a corresponding Broadcast Channel of the cellular internet of things (e.g., a Narrowband Physical Broadcast Channel (NPBCH), a Physical Broadcast Channel (PBCH), or a Broadcast Channel (BCH). It should be noted that even in any power saving mode, the communication transceiver 173 can receive the broadcast message during the time of monitoring the control channel. That is, the embodiment of the present invention can also be applied to the situation where the communication transceiver 173 is in the power saving mode, thereby saving power.
Since the broadcast message includes identification information of the object requested by the remote host 110, the user equipment 170 may confirm whether the broadcast message is a call to itself. If the identification information does not match the identification content of the user equipment, the user equipment 170 ignores the broadcast message. On the other hand, if the identification information matches the identification content of the communication transceiver 173, the communication transceiver 173 will execute the resource access operation according to the broadcast message (step S440) to actively query the indication content of the remote host 110. The communication transceiver 173 decrypts the payload (payload) of the broadcast message according to the security key recorded in the broadcast message to obtain the information related to the subsequent resource access operation. The resource access operation is, for example, a Random access (Random access) operation, or other radio resource contention and/or request related operation, and the resource access operation is, for example, transmitted via a corresponding Random access or resource assignment channel (e.g., a Narrowband Random access channel (NPRACH), a Physical Random Access Channel (PRACH), or a Random Access Channel (RACH) of the cellular internet of things.
After the communication transceiver 173 performs the resource access operation and confirms that the radio resource is acquired, the configuration command transmitted by the base station 150 is received via the radio resource (step S450). That is, the embodiment of the invention can receive the configuration command initiated by the remote host 110 through the communication transceiver 173 while the processor 171 is still in the sleep mode. The configuration command is transmitted via a Channel used for data or Control signaling (signaling), for example, a Narrowband Physical Downlink Control Channel (NPDCCH), a Narrowband Physical Downlink Shared Channel (NPDSCH), a Physical Downlink Control Channel (PDCCH), or a Downlink Shared Channel (DCH).
Then, the communication transceiver 173 can set the wake-up configuration according to the configuration command (step S460). In one embodiment, the power saving configuration is related to sleep or listening timing of the power saving mode, and the communication transceiver 173 can adjust the sleep or listening timing according to the configuration command without waking up the processor 171. The sleep or listening occasion may be an occasion to listen to a control channel, an occasion to enter from a low power/idle state, or a time to wake up from a low power/idle state, and shortening or lengthening the time of the low power/idle state will affect the power consumption of the user equipment 170.
Taking NB IoT as an example, the Power Saving modes at least include Power Saving Mode (PSM) and Extended Discontinuous Reception (eDRX). Fig. 5A to 5C are timing diagrams of the power saving mode. Referring to fig. 5A, if the communication transceiver 173 is in the power saving mode, the communication transceiver 173 monitors paging within the time parameter T3324 before the power saving mode period PSM arrives. When the power saving mode period PSM arrives, the communication transceiver 173 will not be able to connect through the network or even turn off the circuit until the time parameter T3412 expires (i.e., a Tracking Area Update (TAU) period arrives). Referring to fig. 5B and 5C, if the communication transceiver 173 is in the enhanced discontinuous reception mode, the communication transceiver 173 will monitor or listen to the control channel every discontinuous reception period in the connected (connected) state (fig. 5B); while in idle (idle) state (fig. 5C), a longer Paging cycle will be allowed within the new Paging Time Window (Paging Time Window). In this embodiment, the communication transceiver 173 may modify the time duration, such as the time parameter T3412, the drx cycle or the paging time window, according to the power saving configuration.
In another embodiment, the power saving configuration is related to switching the power saving mode, and the communication transceiver 173 switches to another power saving mode according to the configuration command without waking up the processor 171. Taking NB IoT as an example, assuming that the communication transceiver 173 originally uses the power saving mode, the power saving configuration indicates to switch to the enhanced discontinuous reception mode, for example; alternatively, if the communication transceiver 173 originally uses the enhanced discontinuous reception mode, the power saving configuration may indicate a switch to the power saving mode. It should be noted that, the switchable content of the communication transceiver 173 may be different according to the power saving mode types supported by different communication technologies, and the user may change the power saving mode switching type according to actual requirements.
It is noted that in the embodiment where the power saving configuration is related to the sleep or listening time for switching the power saving mode or the power saving mode, the communication transceiver 173 can update the configuration by itself without waking up the processor 171, thereby saving the overall power consumption of the ue 170. For example, the ue 170 is an intelligent tracking device, and the user returns to home from a working environment, and the power saving configuration can be set by the remote host 110 to adjust the update frequency of the location feedback.
In another embodiment, the power saving configuration is associated with the remote wakeup processor 171 (i.e., remote wakeup link function), and the communication transceiver 173 wakes up the processor 171 according to the configuration command, and the processor 171 switches from the sleep mode to the normal mode. The processor 171 may then interface with and perform data transfer with the remote host 110 via the communication transceiver 173. That is, the processor 171 may be switched from the sleep mode to the normal mode by the remote host 110 actively waking up remotely. Therefore, the user can remotely wake up and control the UE 170 in a remote real-time manner without worrying about excessive power consumption of the UE 170.
To assist the reader in understanding the spirit of the embodiments of the present invention, the general flow is described below using NB IoT as an example.
Fig. 6 is a flowchart of a narrowband internet of things network according to an embodiment of the present invention. Referring to fig. 6, the base station 150 receives a configuration command for the ue 170 adjustment from the remote host 110 via the network 130 (step S610). The base station 150 will include the identification information and security key of the specified ue 170 in the broadcast message, and then send the broadcast message through the narrowband physical broadcast channel (step S620). The ue 170, knowing its own assignment and response target from the broadcast message (step S630), transmits a radio resource Control Connection Request message (radio resource Control Connection Request) via the narrowband physical random access channel (step S640) to start performing a random access operation. The base station 150 transmits a Radio Resource Control Connection Setup (Radio Resource Control Connection Setup) message (step S650), and the ue 170 returns a Radio Resource Control Connection Setup Complete message (step S660) to end the random access operation. Next, the base station 150 may transmit the configuration command through the narrowband pdcch or the narrowband pdsch (step S670). In step S680, the ue 170 receives the configuration command, and can switch the power saving mode or change the sleep or listening timing according to the configuration command. Alternatively, the configuration command is associated with the remote wakeup processor 171, and the processor 171 wakes up and connects to the remote host 110 through a Narrowband Physical uplink shared channel (NPUSH) for data transmission (step S690).
It should be noted that, according to the types of the cellular internet of things networks, the content of the used channels and the power saving configuration may be different, and the user may adjust the channel according to the actual requirement.
In summary, the power saving mechanism of the cellular internet of things can only achieve one-way communication (i.e., the ue needs to actively connect to the remote host to wake up the host system/processor remotely). The embodiment of the invention can achieve a two-way communication mechanism (namely, the two-way communication mechanism can be actively initiated by the remote host), so that the main system/processor of the user equipment is updated in a sleep mode (even a communication transceiver of the user equipment can be in a power-saving mode), thereby achieving the effect of saving power.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
