Description

Fast sleep mechanism triggering method and system

The invention relates to a fast sleep mechanism triggering method and system, in particular to a fast sleep triggering method and system for a palm-type electronic device.

The fast dormancy mechanism is a well-known technique for saving power consumption of handheld electronic devices using data services in mobile networks. The purpose of the fast sleep mechanism is to allow the network to transfer the handheld electronic device to a more power-saving mode when the handheld electronic device does not need to transmit data. At present, the triggering of the fast sleep mechanism is left to each manufacturer to develop by itself, and is generally triggered based on the activity of the main processor of the handheld electronic device and the loop of the sleep of the main processor. That is, when the main processor completes all active tasks and is ready to enter the sleep mode, the kernel layer of the main processor notifies the Radio Interface Layer (RIL) to trigger fast sleep, and then the RIL sends a fast sleep instruction. To the modem, the fast sleep instruction notifies the modem to perform a fast sleep.

This triggering mechanism is unstable and susceptible to changes in the architecture of the host processor. Based on the construction principle of the main processor, the main processor may have entered a sleep state when the sorted fast sleep instruction has not been processed, so the fast sleep instruction has been followed by the main routine before the RIL sends the fast sleep instruction to the data machine. The processor goes to sleep. Therefore, it is necessary to seek a trigger mechanism that is stable, less susceptible to the main processor architecture, and can improve the power saving efficiency of the handheld electronic device.

In view of the above, it is necessary to provide a fast sleep mechanism triggering method and system to trigger a fast sleep mechanism of a handheld electronic device.

The fast sleep mechanism triggering method is applied to a palm-sized electronic device, and the method includes the following steps: monitoring step: monitoring traffic of the handheld electronic device; determining step: determining whether the traffic does not change within a preset time, when When the traffic does not change within the preset time, the triggering step is performed; otherwise, the monitoring is continued; the triggering step: triggering the fast sleep mechanism of the handheld electronic device.

The fast sleep mechanism triggering system runs in a palm-sized electronic device, and the system includes: a monitoring module for monitoring traffic of the handheld electronic device; and a determining module for determining whether the traffic is not within a preset time A change module is triggered to trigger a fast sleep mechanism of the handheld electronic device when the traffic does not change within the preset time.

Compared with the prior art, the fast sleep mechanism triggering method and system of the present invention achieves the purpose of triggering the fast sleep mechanism by monitoring the traffic in the handheld electronic device, thereby achieving the purpose of stably triggering the fast sleep mechanism. This flow-based judgment method is not affected by the change of the main processor architecture, and is closer to the intended purpose of the fast sleep mechanism, which can effectively improve the power saving efficiency of the handheld electronic device.

FIG. 1 is a structural diagram of a preferred embodiment of the fast sleep mechanism triggering system of the present invention.

The fast sleep mechanism triggering system 10 is operated in the handheld electronic device 1. The handheld electronic device 1 further includes a main processor 11 and a data machine 12. The handheld electronic device 1 can be a mobile communication device such as a mobile phone, a personal digital assistant (PDA), or a tablet computer.

The large amount of data transmission in the palm-sized electronic device 1 can seriously consume the battery capacity of the handheld electronic device 1. When the handheld electronic device 1 is connected to the mobile communication network, a large amount of data transmission is not required from time to time (for example, when the downloaded web content is read for a long time), at this time, the mobile communication network connection is not disconnected. Under the premise, reducing the battery capacity consumption, thereby extending the life of the handheld electronic device 1 battery, becomes a necessary technology. At this point, the fast sleep mechanism is generally used.

The fast sleep mechanism can bring the connection of the palm-type electronic device 1 into a sleep state when the handheld electronic device 1 has no data transmission in use, thereby causing the handheld electronic device 1 to enter a power-saving state. The no data transmission is in use, and the flow value generated by the data transmission is always the same value within a certain time interval. For example, when the content of the downloaded webpage is read for a long time, the traffic value generated by the data transmission is read once every second. If the traffic value of each read is equal (for example, 2 KB), the handheld electronic device is described. 1 No data transmission is in use.

The fast sleep mechanism triggering system 10 includes a monitoring module 100, a determining module 101, a triggering module 102, and a setting module 103. The function of each module will be described in detail in conjunction with the flowchart of FIG. 2.

As shown in FIG. 2, it is a flowchart of a preferred embodiment of the method for triggering a fast sleep mechanism of the present invention.

In step S10, the monitoring module 100 monitors the traffic of the handheld electronic device 1.

When the palm-type electronic device 1 performs data transmission with the mobile communication network, traffic is generated. The data transmission with the mobile communication network includes transmitting data to and receiving data from the mobile communication network. When transmitting the data, the main processor 11 sends the data to the data machine 12 through the RIL, and the data machine 12 transmits the data to the mobile communication network; when receiving the data, the data machine 12 receives the data sent by the mobile communication network. The data machine 12 transmits the data to the RIL in the main processor 11. The monitoring module 100 monitors the flow rate of the handheld electronic device 1, that is, monitors the flow status of the RIL in the main processor 11, and stores the flow value generated by the current data transmission in the RIL.

In step S12, the determining module 101 determines whether the flow does not change within a preset time. When the flow does not change within the preset time, step S14 is performed; otherwise, the monitoring is returned. The preset time is set according to parameters such as the performance of the handheld electronic device 1 and the connection status with the mobile communication network, for example, any one of 2 seconds to 10 seconds.

The process of determining whether the flow rate 101 has not changed within the preset time period by the determination module 101 will be described in detail in FIG.

In step S14, the trigger module 102 triggers a fast sleep mechanism of the handheld electronic device 1.

In this step, the trigger module 102 triggers the fast sleep mechanism by: controlling the RIL in the main processor 11 to send a fast sleep command to the data machine 12, and the data machine 12 transmits a radio resource control (RRC) protocol. The connection release information is sent to the mobile communication network. After the mobile communication network receives the RRC connection release information, the mobile communication network releases the network resources that the handheld electronic device 1 is using, and the handheld type The electronic device 1 enters a power saving state.

As shown in FIG. 3, it is a judgment sub-flow chart of a preferred embodiment of the fast sleep mechanism triggering method of the present invention.

In step S120, the determining module 101 reads the current monitored flow value of the monitoring module 100 from the RIL in the main processor 11.

Step S122, the determining module 101 determines whether the read flow value meets a preset requirement. When the read flow value does not meet the preset requirement, step S124 is performed; otherwise, step S126 is performed.

The judgment module 101 defaults to the flow value read by the first time that meets the preset requirement. The steps to determine whether the read traffic value meets the preset requirements are as follows:

When a flow value is obtained, the current flow value and the previous flow value adjacent to the current flow value are taken in the order of reading to obtain two flow values arranged in order. When the two flow values are equal, it is determined that the flow value meets the preset requirement. When the two flow values are not equal, it is determined that the flow value does not meet the preset requirement.

Step S124, the determining module 101 determines that the flow rate changes within the preset time, and returns to step S10.

In step S126, the determining module 101 performs a superimposing operation on the count value.

Before the step S126, the setting module 103 sets an initial value for the count value. There are two cases of this initial value, one is the initial value of time, and the other is the initial value of the number of times. When the initial value is the initial value of the time, the initial value set by the setting module 103 is the value of the preset time; the preset time is the interval time for reading the flow value, and the preset time is performed by N (N is greater than 1) The integer value is equally divided, and the time value obtained after N equal division is the preset time. When the initial value is the initial value of the number of times, the initial value set by the setting module 103 is 1.

When the initial value is the initial value of the time, the superimposition operation on the count value is to add the count value to the value of the preset time; when the initial value is the initial value of the number of times, the superimposition operation on the count value is performed to add the count value. 1 operation.

Each initial value corresponds to a preset value, which is different depending on the type of the initial value. When the initial value is the initial value of the time, the preset value is the value of the preset time. When the initial value is the initial value of the number of times, the preset value is an N value that divides the preset time by N. For example, the preset time is 6 seconds, and the preset time is divided into three equal parts. When the initial value is the initial value of the number of times, the preset value corresponding to the initial value is 3.

In step S128, the determining module 101 determines whether the count value is smaller than the preset value. When the count value is less than the preset value, step S130 is performed; otherwise, step S132 is performed.

In step S130, the determining module 101 waits for the preset time, and returns to step S120.

In the loop process of the above steps S120 to S130, one flow value can be obtained for each reading. The flow value is named according to the sequence number of the read, and the flow value obtained by the first reading is named as the first flow value. For example, if the flow value is read for the first time, it is named as the first flow value. In step S122, when it is determined whether the read flow value meets the preset requirement, it is determined according to the currently read flow value and the previous flow value adjacent to the current flow value.

In step S132, the determining module 101 determines that the flow rate has not changed within the preset time, and performs step S14.

The traditional triggering method, when multiple applications are open, applications that do not use the mobile communication network are still considered as factors that trigger the fast sleep mechanism. The present invention monitors the traffic during data transmission and determines whether to trigger the fast sleep mechanism according to the traffic, that is, does not consider an application that does not use the mobile communication network, and is more suitable for the purpose of using the fast sleep mechanism than the conventional trigger method.
