Description

Method for receiving log information and electronic device therefor

Various embodiments disclosed in this document relate to a method of receiving log information and an electronic device for performing the method.

The electronic device may perform wireless communication using a modem device. For example, the modem device may be connected to the modem device through a universal serial bus (USB) interface, and may perform wireless communication using the modem device. The modem device may be a USB communication device class (CDC) device. The USB CDC is a device class designated by an implementer's forum (USB-IF), and may include a communication device connectable through USB, such as an Ethernet device and a modem device. The USB CDC device may be configured to provide communication based on an ethernet networking control model (ECM), a network control model (NCM), and/or a mobile broadband interface model (MBIM).

For example, a host device such as a desktop, laptop, or tablet may communicate with a modem device based on MBIM. The modem device may be a modem device that supports cellular communication. MBIM may define a protocol for connectivity between a host device and a modem device. A mobile broadband (MBB) device may be a USB device supporting a single function or multiple functions. The single function or multiple functions may include an MBIM function. The MBIM function may be referred to as a USB function within a USB device that is compatible with the MBIM specification.

An electronic device may perform wireless communication using a modem device. In this case, the electronic device may receive data through an interface (eg, USB) between the electronic device and the modem device. The first generation USB 3.1 standard can support a transfer rate of up to 5 Gbps, and the second generation USB 3.1 standard can support a transfer rate of up to 10 Gbps. This is the theoretical maximum transmission rate on the physical layer, and the transmission rate on the application layer including the IP (internet protocol) packet may be lower than the transmission rate on the physical layer. For example, the transmission speed of the IP packet that the electronic device can receive through the modem device through the USB interface may correspond to about 1 Gbps.

The recently deployed 5G mobile communication can support a transmission speed of about 20 Gbps. When the modem device supports communication having a high transmission rate, such as 5G mobile communication, data throughput may be limited due to the transmission rate of the USB interface. Also, when the electronic device receives log data from the modem device, data throughput may decrease due to the reception of the log data.

According to an embodiment, the electronic device 201 may be connected to the modem device 301 through the communication interface 280 . The electronic device 201 may perform wireless communication using the modem device 301 connected through the communication interface 280 .

According to an embodiment, the electronic device 201 determines whether to receive log information including event information of the modem device 301 based on the operation state of the electronic device 201 or the communication state of the modem device 301 . can The electronic device 201 may determine to receive log information when the operating state of the electronic device 201 is expected to decrease throughput for cellular communication. When the communication state indicated by the modem device 301 indicates a relatively low throughput, the electronic device 201 may determine to receive log information. When the communication state of the modem device 301 observed by the electronic device 201 indicates a relatively low throughput, the electronic device 201 may determine to receive log information.

For example, when the electronic device 201 determines that the electronic device 201 enters the sleep mode, the electronic device 201 may determine to receive log information from the modem device 301 . When the electronic device 201 determines to enter the sleep mode, the electronic device 201 may transmit a request for reception of log information to the modem device 301 . For example, the state of the electronic device 201 may be determined based on a global system state of an advanced configuration and power interface (ACPI) standard. For example, the GO state is an operating state, and may be referred to as a state in which the processor 220 arranges and executes user mode (eg, application) threads. The G1 state is a sleep state, in which the electronic device 201 consumes a small amount of power and user mode threads are not executed. The G2 state is a state in which the electronic device 201 consumes minimal power, and is a state in which no user mode or system mode code is executed. The G3 state is a state in which the electronic device 201 is mechanically turned off and power is not supplied to the electronic device 201 . Since the G0 state is a state in which network traffic may increase, the electronic device 201 may not receive log information. In the case of the G2 or G3 state, since it is impossible to establish a channel for receiving log information, the electronic device 201 may not receive log information. Accordingly, when the transition to the G1 state is determined, the electronic device 201 may receive log information.

The G1 state may be further divided into S0ix, S1, S2, S3, and S4. The S0ix state is a modern standby state, and may mean a state in which some components of the processor 220 are turned off. The S1 state is a standby mode that consumes little power, and is a state in which all system contexts are maintained. The S2 state is a state in which power to the processor 220 is cut off, and the processor 220 and the system cache context are lost. The S3 state is a power saving mode, in which all system contexts are lost, but power supply to the main memory is maintained. The S4 state is a hibernation state, in which the hardware platform has stopped supplying power to all devices. Entering the S0ix state may mean that the use of the electronic device 201 by the user is reduced. The electronic device 201 may determine to receive log information when the entry into the S0ix state is determined.

For example, the electronic device 201 may determine to receive log information based on information received from the modem device 301 . The electronic device 201 may receive a signal indicating that the data throughput of the modem device is less than a set value from the modem device 301 through the communication interface 280 . In one example, the modem device 301 receives a signal indicating that the data throughput is less than a set value when network traffic is reduced or the system of the modem device 301 is expected to enter an idle state for a specified period of time. (eg, a signal including OID_WWAN_NETWORK_IDLE_HINT set to a specified value) may be transmitted to the electronic device 201 . When the modem device 301 enters a data dormant state, it may transmit a signal indicating that the data throughput is less than a set value. The modem device 301 may heuristically determine the entry into the data dormant state. When a signal indicating that the data throughput is less than a set value is received from the modem device 201 , the electronic device 201 may store the state of the modem device 301 as a data dormant state in the memory 230 . The electronic device 201 may determine to receive log information when the modem device 301 is in the data dormant state or when a signal indicating that the data throughput is less than a set value is received.

For example, the electronic device 201 may determine to receive log information based on data throughput received through the modem device 301 . An operating system (OS) of the electronic device 201 may acquire information (eg, Ethernet performance) of network traffic received through the modem device 301 . Based on the network traffic information, if the data throughput received through the modem device 301 is less than a specified value, the electronic device 201 may determine to receive log information.

According to an embodiment, when the reception of log information is determined, the electronic device 201 may transmit a request for reception of log information to the modem device 301 . The request for reception of log information may include a request for connection of a channel for reception of log information. The electronic device 201 may establish a channel (eg, a data service stream (DSS) channel) for receiving log information with the modem device 301 and receive log information through the established channel. After receiving the log information, the electronic device 201 may disconnect the established channel. When log information is received according to the determination of entering the sleep mode, the electronic device 201 may enter the sleep mode after receiving the log information.

According to an embodiment, the electronic device 201 may store the received log information in the memory 230 . The electronic device 201 may diagnose the modem device 301 using log information stored in the memory 230 . The electronic device 201 may receive log information from an external electronic device (not shown), and may receive a diagnosis result based on the log information from the external electronic device. The electronic device 201 may display troubleshooting information according to the diagnosis on the display 260 .

According to an embodiment, while receiving the log information, the electronic device 201 may determine whether to stop receiving the log information. For example, when the state of the electronic device 201 is switched from the sleep mode to the working mode while receiving log information, when the data throughput of the modem device 301 increases to a specified value or more, or when the modem device 301 When a request to stop copying log information is received from , the electronic device 201 may stop receiving log information. The electronic device 201 may transmit a connection release request to the modem device 301 in response to interruption of reception of log information. When the reception of the log information is not completed, the electronic device 201 may continue from the point where the reception of the log information is terminated when receiving the log information later.

According to an embodiment, the electronic device 201 may receive log information based on a signal received from the modem device 301 . For example, when the amount of log information stored in the modem device 301 is equal to or greater than the specified first amount, or when the remaining amount of the log storage is less than the specified first value, the modem device 301 instructs reception of log information A command may be transmitted to the electronic device 201 . In this case, the electronic device 201 may receive the log information regardless of the state of the electronic device 201 or the communication state of the modem device 301 . In one example, the modem device 301 may delete the transmitted log information together with the transmission of the log information. The modem device 301 may transmit a command instructing to stop copying of log information to the electronic device 201 when the amount of log information is less than the second specified amount or when the remaining amount of the log storage is greater than or equal to the specified second value. have.
