Description

Standby method, system and terminal equipment

[ technical field ] A method for producing a semiconductor device

The present application relates to the field of standby response technology of a terminal device, and in particular, to a standby method, a standby system and a terminal device.

[ background of the invention ]

The main continuous power consumption behaviors of the mobile phone during standby (without user operation or user-perceivable activities such as listening to songs, navigating, downloading and the like) comprise:

1) maintaining periodic heartbeat messages of a PUSH message channel;

2) the periodic heartbeat message between the instant messaging application and the server side;

3) standby overhead of a mobile phone communication subsystem (Modem, WiFi) to maintain network connection;

4) the standby overhead required for the handset to wake up from sleep.

Wherein 1, 2 heartbeat services account for about 20% +, of the standby power consumption overhead.

The mobile phone can be functionally divided into several subsystems:

1) application subsystem

The CPU is a commonly-known CPU, and 2 Cortex-A76 Based 2.86GHz +2 Cortex-A76 Based 2.36GHz +4 Cortex-A551.95GHz indicates that the CPU is an ARM architecture with 2 big cores, 2 middle cores and 4 small cores, as indicated by a parameter called P40.

The normal service depends on the operation of the application subsystem, the operation frequency of the application subsystem is high, and correspondingly, the power consumption is high. Particularly for heavy-load applications such as games and photographs, the CPU is frequently scheduled on a high-frequency big core to obtain a good user experience.

2) Communication subsystem

The communication subsystem comprises a Modem, WiFi, Bluetooth and the like, and can be triggered to operate during data interaction, and generally speaking, the application subsystem can participate in the message receiving and transmitting process of the communication subsystem.

3) MCU (Microcontroller Unit, micro-control Unit)

And the low-power consumption subsystem is mainly used for reducing the awakening times of the application subsystem, such as sensor state collection, and awakening the application subsystem if necessary after the sensor state collection is processed on the MCU. Due to the low operation frequency, the complex and heavy-load service cannot be supported, but the power consumption overhead is low.

In the prior art, in one implementation, a network-side proxy server replaces a mobile phone to send a heartbeat message, so as to reduce the number of times of waking up the mobile phone. That is, a server is deployed on the network side, and the server periodically acquires the state of the mobile phone (from the state of the access side device stored in the base station or the controller), starts the proxy heartbeat service if the state is in an active state, and stops the proxy heartbeat service if the state is not in an active state. However, this embodiment has the following disadvantages:

1. the network state of the mobile phone cannot represent the real-time state of the application on the mobile phone, and the application state is possibly identified by mistake;

2. the heartbeat message formats of all applications are not uniform, and the heartbeat message content can be updated regularly due to safety reasons, so that the message formats of the proxy server are frequently updated, and the feasibility is low.

In the prior art, another implementation mode is to adopt data transceiving of a Modem proxy application subsystem in a mobile phone, so as to reduce frequent awakening of the application subsystem. The Modem acquires the information of the required proxy data service, and automatically carries out periodic specified data transceiving on the Modem without participation of an application subsystem in the process. However, this embodiment also has disadvantages: the mode of connecting the mobile phone with the network is various, the mode, WiFi and BT are common, and the proxy service can take effect in a full scene only by being deployed on the mode, WiFi and BT one by one. However, the agent service is customized and deployed on different chips, so that the difficulty is high and the feasibility of full coverage is low.

[ summary of the invention ]

By the scheme provided by the embodiment, the micro control unit has the function of analyzing the downlink message, so that some simple service messages can be processed without waking up the application subsystem, and the power consumption is reduced.

Example 2

As shown in fig. 2, a standby method provided in embodiment 2 of the present application is provided, by which standby power consumption of a terminal device disclosed in embodiment 1 of the present application can be significantly reduced when the terminal device is in a standby state. The standby method comprises the following steps:

step 100: the application subsystem configures the message rules and sends the message rules to the micro control unit.

Step 200: the micro control unit forwards the message rule to the communication subsystem.

Step 300: the communication subsystem receives the downlink message of the network side and forwards the downlink message matched with the message rule to the micro control unit.

Step 400: and the micro control unit sends a confirmation response message and a periodic standby service message to the network side through the communication subsystem.

The standby method transfers the awakening service of the terminal equipment from the application subsystem to the micro control unit, the micro control unit executes the message rule, processes the downlink message of the network side and sends the message to the network side, so that when the downlink message of the network side is received, the application subsystem with higher power consumption is awakened to process the downlink message, the message is processed only in the micro control unit with the unified message receiving and sending function and low power consumption, the message service proxied by the terminal equipment does not need to be awakened to be processed by the application subsystem, and the lower power consumption can be kept.

As shown in fig. 3, Step100 specifically includes the following steps:

step 101: the application subsystem generates configuration information.

Step 102: and the application subsystem generates a message rule according to the configuration information.

Step 103: the application subsystem sends the message rule to the micro control unit.

In Step100, the specific process of configuring the message rule by the application subsystem and sending the message rule to the micro control unit is that the application subsystem creates the message rule for the micro control unit and the communication subsystem to use, so that not only can frequent awakening of the application subsystem to process a downlink standby message at the network side be avoided, but also a new proxy service can be supported by configuring different message rules, and the expandability of the system is enhanced.

Further, at Step 103: in the step of sending the message rule to the micro control unit by the application subsystem, the application subsystem firstly generates message information according to the message rule, the message sending period and the message format, and then sends the message information containing the message rule to the micro control unit. Before processing the message transceiving service, the application subsystem firstly sends the detailed message rule to the micro control unit, so that the micro control unit can better execute the message transceiving service.

As shown in fig. 4, Step300 specifically includes the following steps:

step 301: the communication subsystem receives a downlink message from a network side.

Step 302: the communication subsystem compares the downlink message with the message rules.

Step 303: the communication subsystem sends the downlink message matched with the message rule to the micro control unit, and sends the downlink message not matched with the message rule to the application subsystem.

In the specific Step of Step300, the communication subsystem compares the received downlink message from the network side with the message rule received from the micro control unit, sends the downlink message (i.e. heartbeat message) meeting the message rule to the micro control unit, and sends the message (i.e. non-proxy service message) not meeting the message rule back to the application subsystem, so that the service message is not missed.

As shown in fig. 5, between Step300 and Step400, the following steps are further included:

step 300': and the micro control unit analyzes the received downlink message.

That is, in this standby method, after the three steps of Step300 described above are executed, Step 300' is executed, and Step400 is executed. In the standby method, the micro control unit has the function of analyzing the downlink message, so that some simple service messages can be processed without waking up an application subsystem, and the power consumption is reduced.

Further, as shown in fig. 6, in Step300 ', if the mcu cannot process the downlink packet, Step 301' is executed: the micro control unit forwards the downlink message which cannot be processed to the application subsystem; if the micro control unit can process the downlink message, executing Step 400: and the micro control unit sends a confirmation response message and a periodic standby service message to the network side through the communication subsystem.

In the standby method, only the non-proxy downlink message is transmitted back to the application subsystem, and the application subsystem is awakened at the moment.

Further, in Step400, the micro control unit sends a confirmation response message after receiving the downlink message of the network side, and the micro control unit sends a periodic standby service message. Therefore, the micro control unit can inform the standby state of the terminal equipment on the network side in time, so that a user on the network side can perform corresponding instructions according to the standby state of the terminal equipment in time.

Specifically, the application subsystem 10 is configured to configure message rules and send the message rules to the mcu 20; the micro control unit 20 is configured to forward the message rule to the communication subsystem 30; the communication subsystem 30 is configured to receive a downlink packet from the network side, and forward the downlink packet matching with the packet rule to the micro control unit 20.

The application subsystem 10 is a device for processing a service packet. The mcu 20 is a low power processing subsystem, has a light-load scene processing capability, and can interact with the application subsystem 10 and the communication subsystem 30. The communication subsystem 30 has WiFi (wireless network), Modem (short for Modulator and Demodulator), and other communication elements such as bluetooth, infrared transmitter, and the like. In fig. 7a, the solid data flow represents the data flow direction during normal operation of the mobile phone; in fig. 7b, the solid data stream represents proxy data transceiving by the micro control unit 10 while the handset is in standby.

The main process of interconnecting the micro control unit 20 and the application subsystem 10 includes: the application subsystem 10 configures rules of the messaging agent to the micro-control unit 20; after receiving the downlink message, if the downlink message cannot be processed, the mcu 20 needs to continue forwarding the downlink message to the application subsystem 10. Taking heartbeat proxy as an example, the application subsystem 10 needs to configure port information to the mcu 20, and the application subsystem 10 may also issue a command to the mcu 20 to start or stop proxy functions.

The following is a specific operation of the standby system in two specific application scenarios.

Scene one: when the terminal equipment is in standby, the data transmission and network side response message reception initiated by the application subsystem 10, and the proxy is migrated to the micro control unit 20 to initiate message reception and respond to the network side reply message;

scene two: when the terminal device is in standby, the peripheral device actively sends a data message to the application subsystem 10, and the micro control unit 20 responds to the data message to avoid waking up the application subsystem 10.

In the standby system, the mcu 20 has a protocol stack capability, and the mcu 20 has a protocol stack element for parsing a received message. The element having the Protocol stack can enable the micro control unit 20 to analyze a message (generally, an IP (Internet Protocol) message) forwarded by the communication subsystem 30, and then perform a response process, such as sending an ACK (Acknowledge character) response, that is, a message sent by the standby system to the network side, that is, the standby system tells the network side that the standby system receives the message. Meanwhile, the micro control unit 20 also periodically sends an IP packet with a specified format to the network side.

By adopting the standby system provided in embodiment 3 of the present application, based on the low power consumption characteristic of the micro control unit 20, the standby system has the interconnection capability with the application subsystem 10 and the communication subsystem 30, the application subsystem 10 configures the required data proxy service, and automatically performs data transceiving of the proxy service in a specified scene, and the application subsystem 10 does not need to participate in the proxy process, so that the purpose of reducing the standby power consumption is achieved. The standby system can transfer the awakening service of the terminal equipment from the application subsystem to the micro control unit, the micro control unit executes the message rule, processes the downlink message of the network side and sends the message to the network side, so that when the downlink message of the network side is received, the application subsystem with higher power consumption is required to be awakened to process the downlink message, the message is only processed in the micro control unit with the unified message receiving and sending function and low power consumption, the message service proxied by the terminal equipment does not need to be awakened to be processed by the application subsystem, and the lower power consumption can be kept.
