Description

Synchronous transmission method and device of nonvolatile storage file and embedded equipment

Technical Field

The present disclosure relates to the field of embedded technologies, and in particular, to a method and an apparatus for synchronously transmitting a nonvolatile storage file, and an embedded device.

Background

In a 4G network, a Radio Resource controller (RRC for short) is present in an embedded device, and is configured to allocate Radio resources and send related signaling, where a main part of Control signaling between a UE and a UTRAN is an RRC message, and the RRC message carries all parameters required for establishing, modifying, and releasing a mac layer and a physical layer protocol entity, and also carries some signaling of an NAS (non-access stratum), such as MM, CM, SM, and the like.

Since the power supply capacity of the mobile device is a key factor affecting the use of the device, and the device is not transmitting data all the time, it will certainly consume a large amount of power if the device is always in a high-power connection state, and a mechanism is needed to regulate the state of the device to save power. The power supply is in a high-power state when data are transmitted, and is in an idle state when data are not transmitted, so that the power of equipment can be well saved. This mechanism is the RRC state machine, which is implemented differently in different network standards. LTE-RRC state machine: the 3GPP standard defines a complete state machine that describes the power state of each device connected to the network.

RRC is idle: the radio module of the device is in a low power state (< 15 mW) listening only for control signals from the network. Clients in the operator network have no radio resources.

RRC connection: the radio module of the device is in a high resolution state (1000-. The operator network specifies the data bearer and also allocates dedicated radio resources.

Non-Volatile Memory (NVM), which refers to system files that need to be stored on a Non-Volatile physical storage medium, can be saved after power supply is removed, and is accepted when the next power supply system operates again, is an embedded common file use storage form.

The embedded RTOS is sensitive to power consumption in design, and the RRC state of 4G mainly receives and transmits network data, and has a high probability of modifying file related data and a high probability of refreshing NVM-files. These tasks wake up the main chip multiple times, increasing power consumption.

Therefore, the existing nonvolatile storage file has the technical problem of increasing power consumption.

In addition, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the aspects may be practiced without these specific details.

Referring to fig. 1, a schematic flowchart of a method for synchronously transmitting a nonvolatile storage file according to an embodiment of the present disclosure is shown, where the method is applied to an embedded device. As shown in fig. 1, the method mainly comprises the following steps:

s101, monitoring whether a radio resource controller of the embedded equipment enters an idle state from a connection state;

the synchronous transmission method of the nonvolatile storage file provided by the embodiment of the disclosure is applied to a synchronization strategy of a radio resource controller between state switching. Specifically, the radio resource controller has 2 states, namely an idle state and a connected state. When the embedded device is in an idle state, it cannot send or receive any data. To transmit data, it is necessary to synchronize with the network by listening to the network and then send a request to the RRC to switch it to the "connected" state. After the wireless signal tower is switched to the connection state, the network environment between the wireless signal tower and the LTE equipment is ready and can transmit data at any time. However, if one of the communicating parties finishes the data transmission, the RRC needs to determine when to switch the device to a low power state. The RRC state machine relies on a set of timers to trigger RRC state switching. Since the power required for the connection state is high, to do the operation more efficiently, there are several sub-states:

continuously receiving: highest power, network environment ready, allocated network resources.

Short discontinuous reception (short DRX): the network environment is ready and no network resources are allocated.

Long discontinuous reception (long DRX): the network environment is ready and no network resources are allocated.

The only difference between long DRX and short DRX is that the sleep time before waking up is different, all else being the same.

In order to handle the task centrally, it is necessary to monitor whether the radio resource controller has entered an idle state from a connected state.

In specific implementation, according to a specific implementation manner of the embodiment of the present disclosure, before the step of monitoring whether the radio resource controller of the embedded device enters the idle state from the connected state, the method may further include:

In this embodiment, the connection RRC _ CONNECT state of the radio resource controller is completed to enter the IDLE RRC _ IDLE state of the radio resource controller, which is used as a trigger condition for the NVM _ Sync synchronization entry procedure for non-volatile storage.

S102, when the radio resource controller enters an idle state from a connection state, a synchronous transmission action is immediately executed on the nonvolatile storage file.

And triggering a non-volatile storage file synchronization program when the radio resource controller RRC is monitored to enter an idle state from a connected state, and immediately executing a synchronous transmission action on the non-volatile storage file.

According to a specific implementation manner of the embodiment of the present disclosure, as shown in fig. 2, the step of immediately performing a synchronous transmission action on the nonvolatile storage file when the radio resource controller enters an idle state from a connected state includes:

s201, when the radio resource controller enters an idle state from a connection state, judging whether a synchronous transmission action needs to be executed on a nonvolatile storage file in the embedded equipment;

if the synchronous transmission action is required to be executed on the nonvolatile storage file in the embedded device, S202 is executed, and the synchronous transmission action is immediately executed on the nonvolatile storage file;

and if the synchronous transmission action does not need to be executed on the nonvolatile storage file in the embedded device, executing S203 and directly entering an idle state.

In this embodiment, it is considered that when the RRC state mainly receives and sends network data, there is a need to modify and store file-related data with a high probability or refresh the non-volatile storage files NVM-files, but there is also a need for synchronization tasks such as modification and refresh, so that a determination process of synchronization requirements is increased.

As shown in fig. 2, when the radio resource controller enters the idle state from the connected state, it is first determined whether a synchronous transmission action needs to be performed on the non-volatile storage file of the embedded device. If the synchronous transmission action needs to be executed, as shown in fig. 3, the synchronous transmission action is immediately executed on the nonvolatile storage file; otherwise, if the synchronous transmission action is not required to be executed, the idle state can be directly entered.

In the synchronous transmission scheme of the nonvolatile storage file provided by the embodiment, when the radio resource controller is switched from the connection state to the idle state, the node performs a synchronous transmission action of the nonvolatile storage file once, so that effective tasks are concentrated in continuous time slices as much as possible, and the number of times that the main chip is awakened by the tasks is relatively reduced, thereby achieving the purpose of saving power consumption.

On the basis of the above embodiments, the embodiments of the present disclosure further specifically limit the synchronous transmission execution process. According to a specific implementation manner of the embodiment of the present disclosure, the step of performing the synchronous transmission action on the nonvolatile storage file may include:

The NVM physical media are external device attributes, read-write access needs to be matched with software drive of the external device, and the read-write access efficiency is relatively low, so that a layer of cache is additionally introduced between a processor and the external NVM media in a general embedded system, the physical attributes of the cache have high-efficiency access read-write attributes, but generally have volatile attributes, namely the cache can be cleared when power failure occurs.

The connection of the NVM-files after the physical synchronization and the power supply of the peripheral equipment is ensured through the following two actions:

1) and loading the NVM-files into the cache area from the peripheral physical medium when the system runs.

2) And synchronously updating the NVM-files in the cache area to a peripheral physical storage medium in the system operation period.

The synchronous data transmission process comprises the following steps: the data is carried from the cache to the physical peripheral for storage, so that the data can be guaranteed not to be lost as far as possible, the data can be effectively carried in the next starting, and the actual physical peripheral and a driver program accessed by the cache can be combined in the period.

As shown in fig. 3 and 4, under the condition of software scheduling permission, the transmission task in the RRC _ CONNECT state and the NVM _ Sync task are processed as intensively as possible, so as to concentrate more time slices in the system idle state, and to enter low power consumption more easily.

Furthermore, according to another specific implementation manner of the embodiment of the present disclosure, after the step of performing the synchronous transmission action on the nonvolatile storage file immediately when the radio resource controller enters the idle state from the connected state, the method further includes:

The power required for the connection state is high and there are several sub-states in order to accomplish the operation more efficiently. As shown in fig. 4, there is a state transition delay in switching between adjacent states.

In addition, when the system low power consumption time marking is carried out, the method can further comprise the following steps:

As shown in fig. 4, the overall system enters a fully low power consumption state in cooperation with the processing of other Task tasks, where:

first row: is a time slice diagram of the processing of NVM _ Sync and RRC states.

A second row: the scheduling process is illustrated for the other task T0/T1/T2/T3, where the gray background is the task IDLE state, i.e., only IDLE tasks.

Third row: marking the whole system to meet the period of entering the low power consumption state of the system, namely the system total time slice, and subtracting the distributed time after the RRC _ CONNECT/NVM _ Sync and TASK scheduling and the time of state transition delay, wherein the distributed time is marked by L in figure 4.

In summary, the method provided by the embodiment of the present disclosure is directed to a situation that there is network data interaction in an RRC state, and there is a high possibility that file contents at a device end need to be recorded and rewritten, which results in a need to refresh an NVM file to a non-volatile storage. The NVM _ Sync entry is compacted after entering RRC _ IDLE from RRC _ CONNECT, two types of events are treated and centralized in the wake-up state of the system, namely, the file refreshing Sync is tried immediately after the RRC connection state, the NVM file can be refreshed successfully into a nonvolatile memory more timely, the condition that data is not synchronized or lost due to abnormity is reduced, and the robustness of the system is improved.
