The working process of the CPU is as follows: instructions are fetched from memory or cache, placed in an instruction register, and decoded. It decomposes the instruction into a series of micro-operations, then sends out various control commands, executes the micro-operation series, thereby completing the execution of one instruction. An instruction is a basic command that a computer specifies the type and operands of an execution operation. An instruction is composed of one or more bytes including an opcode field, one or more fields for operand addresses, and some status words and signature codes that characterize the state of the machine. Some instructions also include the operands themselves directly.

Therefore, in the electronic device, all the functional modules, for example: the device comprises a modem (modem), a wireless fidelity (WIFI), a power module, a video module and other functional modules; the tasks are allocated by the CPU, and the execution processing of the functional modules can initiate CPU interruption, so that the load of the CPU is large, and the efficiency of the whole system is low.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

An embodiment of the present invention provides a method for sending uplink data, as shown in fig. 1, including:

101: a modem of the terminal equipment receives uplink data;

the uplink data refers to data sent by the terminal device to the network side, and the uplink data may be derived from application software (here, the application software is an application program, APP for short), for example: WeChat, microblog, Paibao, QQ, mailbox, browser application, video application, gaming application, and the like.

102: the modem determines the type of the uplink data and whether the type of the uplink data meets the requirement of waking up the radio frequency module in a low power consumption mode;

the data type of the uplink data may be what type of data the uplink data belongs to, or may be what kind of data the uplink data needs; for example: QoS (Quality of Service) requirements, delay requirements, etc. for uplink data; for the uplink data with higher requirement on the service quality or lower delay, the uplink data needs to be forwarded as soon as possible; the radio frequency module can be immediately awakened to perform data forwarding.

In this embodiment, the low power consumption mode refers to an abnormal operating mode, and is an operating mode with lower power consumption than the normal operating mode. The low power mode may be a sleep state in which necessary downlink signaling may be received.

103: and under the condition that the type of the uplink data does not meet the requirement of awakening the radio frequency module in the low power consumption mode, caching the uplink data, and under the condition that a preset awakening condition is met, awakening the radio frequency module to enable the radio frequency module to send an analog signal obtained by modulating the uplink data.

In this embodiment, the mode for the modem to wake up the rf module may be that the modem directly sends a wake-up command to the rf module, or may be that the wake-up command is forwarded by the CPU, depending on whether there is a link for direct communication between the modem and the rf module. In addition, the tuning demodulator may also control the operating state of the rf module in other manners, such as: the supply voltage of the modem is controlled by the control power supply module or other modes. The embodiment of the invention does not uniquely limit the way of realizing the awakening of the radio frequency module.

In addition, the predetermined wake-up condition may be: the periodic wake-up radio frequency module may also be a wake-up radio frequency module after a certain amount of data is reached by a cache, or may be a wake-up radio frequency module in any other manner, which is not limited in this embodiment.

In the embodiment, the modem controls the sending function of the uplink data, and in addition, the working mode switching of the radio frequency module is controlled by the modem, so that the power consumption control of the radio frequency module is realized; in the power consumption control process, the CPU is not required to be awakened and the interruption processing is not required to be executed, so that the work of the CPU is deployed into hardware with an intelligent function, on one hand, the load balance is realized, on the other hand, the interruption of the CPU is reduced, the load of the CPU can be reduced, the power consumption of the radio frequency module can be reduced, and the system efficiency of the whole terminal device is improved.

In an alternative implementation manner, an embodiment of the present invention provides a specific example of waking up a radio frequency module in a low power consumption mode, where the specific example is as follows: the modem determining the type of the uplink data, whether the type of the uplink data meets a requirement for waking up the radio frequency module in a low power consumption mode, includes:

the modem determines a quality of service requirement of the uplink data, and if a delay of the quality of service requirement is lower than a predetermined threshold, the modem determines that the requirement for waking up the radio frequency module in the low power consumption mode is met, otherwise, the modem determines that the requirement for waking up the radio frequency module in the low power consumption mode is not met.

In this embodiment, whether the radio frequency module in the low power consumption mode is immediately awakened or not is controlled by the service quality requirement of the uplink data, so that on one hand, the requirement for transmission of the uplink data which is sensitive to the service quality and requires a high requirement can be ensured, on the other hand, the processing quantity of the interrupt and the control of the working time of the radio frequency module are considered, and the electric energy is saved.

In an optional implementation manner, based on that uplink data does not need to wake up the radio frequency module in the low power consumption mode immediately, the uplink data is cached, and in this case, the embodiment of the present invention further provides an implementation scheme that specifically under what kind of circumstances, the radio frequency module in the low power consumption mode can be woken up, as follows: the waking up the radio frequency module until a predetermined wake-up condition is satisfied to enable the radio frequency module to transmit an analog signal obtained by modulating the uplink data, includes:

waking up the radio frequency module until the cached data amount reaches a first preset value, so that the radio frequency module sends an analog signal obtained by modulating the uplink data;

or after the timer is overtime, waking up the radio frequency module to enable the radio frequency module to send an analog signal obtained by modulating the uplink data.

In this embodiment, the first predetermined value is greater than the second predetermined value; the first preset value is a threshold value used for judging whether the data volume is too much and needs to be sent out; the second predetermined value is a condition that it is determined that there is a certain amount of data and that the demand for current data transmission is relatively strong. In a third case, the timer is used for timing a low power consumption mode of the radio frequency module, and the timer is restarted each time the radio frequency module enters the low power consumption mode, where the entering of the radio frequency module into the low power consumption mode may be: the uplink data that is sent after the buffer is sent may also be the uplink data that is sent after being immediately awakened, and the uplink data that is sent after the buffer is sent.

It should be noted that, in this embodiment, if the type of the uplink data meets the requirement of waking up the radio frequency module in the low power consumption mode, the radio frequency module is woken up; the rf module forwards the uplink data just received and the uplink data buffered before that. Therefore, the switching times of the working state of the radio frequency module can be reduced, the working efficiency of awakening the radio frequency module every time is improved, and the total interruption times are reduced.

In an alternative implementation, since the modem receives the uplink data and is known to be sent to the network side, in this case, the modem may assist the terminal device in filtering information, so as to reduce unnecessary uplink data and save traffic, which is specifically as follows: before the modem determines whether the type of the uplink data meets a requirement for waking up the rf module in the low power consumption mode, the method further includes:

analyzing the uplink data, and discarding the uplink data when the uplink data meets a filtering condition; determining whether the type of the uplink data meets the requirement of awakening the radio frequency module in the low power consumption mode or not under the condition that the uplink data does not meet the filtering condition; and under the condition that whether the uplink data meet the filtering condition is not determined, sending confirmation information to the source application of the uplink data, and after receiving a confirmation instruction of a user, executing the determination of the type of the uplink data to determine whether the type of the uplink data meets the requirement of awakening the radio frequency module in the low power consumption mode.

In this embodiment, on one hand, the modem can help the CPU of the terminal device to perform information filtering processing, thereby reducing unnecessary data traffic; on the other hand, the data volume of the uplink data which is unnecessarily transmitted is reduced, the waste of power consumption can be reduced, and the interrupt processing times of the CPU can be reduced. In addition, for those cases where it is not certain whether filtering is to be performed, it may be considered to let the user confirm again. These indeterminate conditions can be defined deliberately as: a case where data is abnormally transmitted.

In an optional implementation manner, the manner in which the wireless communication module wakes up the radio frequency module may be that the wireless communication module directly sends a wake-up instruction to the radio frequency module, may also be forwarded by the CPU, and may also be controlled by the power supply module, based on which the following solutions are provided in this embodiment: the above-mentioned radio frequency module of awaking includes:

and after determining that the cached uplink data is sent completely, the modem sends a control instruction to the power supply module, so that the power supply module reduces the power supply voltage for the radio frequency module, and the radio frequency module enters a low power consumption mode.

In this embodiment, the modem controls the power module to implement the operating mode control of the rf module, and since the power is provided by the power module, sending the control command to the power module may facilitate further power provision and power consumption management of the power module.

In an optional implementation manner, the sending a control instruction to a power module to enable the power module to increase a supply voltage to the radio frequency module includes:

the modem sends a control command to the power module through the communication connection between the modem and the power module, so that the power module increases the power supply voltage to the radio frequency module.

In this embodiment, there is a direct communication link between the modem and the power supply module, and the direct communication link may be a bus or others; therefore, the modem and the power supply module are directly communicated without being processed by the CPU, so that the CPU is not required to be awakened completely, and the efficiency is higher.
