In the electronic device provided in the second aspect, the AP is specifically configured to select a plurality of functional modules with frequency points from all the functional modules, and to singly start the functional modules in sequence to test interference of the GSM channel to each functional module.

In the electronic apparatus provided in the second aspect, the AP is further configured to create an interference list, and store the interference list in the memory, where the interference list includes: identification of the functional module that generates the interference and the corresponding GSM channel.

The electronic device in the present application may include a smart Phone (e.g., an Android Phone, an iOS Phone, a Windows Phone, etc.), a tablet computer, a palm computer, a notebook computer, a Mobile Internet device (MID, Mobile Internet Devices), or a wearable device, and the electronic Devices are merely examples, but not exhaustive, and include but are not limited to the electronic Devices, and for convenience of description, the electronic Devices are referred to as User Equipment (UE), a terminal, or an electronic device in the following embodiments. Of course, in practical applications, the user equipment is not limited to the above presentation form, and may also include: intelligent vehicle-mounted terminal, computer equipment and the like.

As for the terminal, when it communicates with the network side device, the network architecture of its communication is as shown in fig. 1, the network architecture includes: an evolved Node B (eNB), a Mobility Management Entity (MME) and a UE, wherein the UE establishes a connection with the MME through the eNB, so that the MME can provide a data service for the UE after authentication is passed. For voice service, the MME may implement Fallback to the Circuit domain for the UE through a Circuit Switched Fallback (CSFB) service, i.e. reverting to a global system for Mobile communications (GSM) communication channel for the voice service.

Referring to fig. 2, fig. 2 provides a flow of a CSFB service, as shown in fig. 2, the CSFB service includes the following steps:

step S200, the mobile terminal sends a call request to the eNB, and the eNB forwards the call request to the MME.

Step S201, the MME sends a circuit domain service notification (CS service notification) to the mobile terminal.

Step S202, the mobile terminal sends an extended service request (extended service request) to the MME.

In step S203, the mobile terminal receives an RRC connection release message transmitted by the eNB, where the RRC connection release message includes a plurality of 2G bins (the plurality of bins specifically includes 75, 85, 95, and 100).

Step S204, the mobile terminal falls back to the 2G network according to the 2G frequency point.

Step S205, the mobile terminal receives a Call Control SETUP (CC _ SETUP) message sent by the mobile switching Server (MSC Server, MSS) to implement the successful access of the MT Call.

With the flow as shown in fig. 2, for the current 4G network, when implementing a voice call, it actually implements a voice service through the GSM channel, but for each UE, it is implementing a voice service through the GSM channelThe maximum transmission power on the same GSM channel may be different because the hardware or parameter adjustment for each UE is slightly different, which results in the maximum transmission power of the GSM channel for each UE being different, and the maximum transmission power difference may result in the GSM channel generating a difference in the interference between different modules, for example, the MIPI frequency of the GSM channel and the display screen is generated, and whether the GSM channel is generated with the MIPI frequency is determined by which GSM channel the UE selects, for example, when the MIPI frequency is 514.5MHz, the interfering GSM channel may be: 40. 41, 42. But how much the GSM channel interference is determined by the transmit power of the GSM channel, in a practical example, for the UE1, which selects 41 channels, it will cause interference to the MIPI frequency of the display screen, but since the UE1 is controlled by the base station, its transmit power on the GSM 41 channel is very small, although interference will be generated, but the degree of interference is small and can be ignored. Since the maximum transmission power of each channel of each UE may be different, it is necessary to detect whether the interference between the maximum transmission power of each channel of each UE and the GSM channel affects the communication, but the existing detection method depends on the detection of a single UE by a detection device, and obviously, the detection method cannot support a large amount (for example, 10)⁴Above level) detection of the UE.

Referring to fig. 3, fig. 3 provides a channel interference testing method of an electronic device, where the method is implemented by the electronic device, and the method is shown in fig. 3 and includes the following steps:

step S301, after the electronic device is started, determining a GSM channel to be tested.

For example, in an optional technical solution of the present application, the GSM channel to be tested in step S301 may be determined by a control device connected to the electronic apparatus, where the control device may specifically be a computer, a server, a base station, a controller, and the like, and a specific implementation manner may be that the GSM channel to be tested of the electronic apparatus is determined by a command, and of course, when the electronic apparatus receives the GSM channel to be tested and is ready to be tested, a confirmation message may be sent to the control device to inform the control device.

Step S302, the electronic device locks a legal Power Control Level (PCL) range of the GSM channel according to the GSM channel, and selects a maximum Power Level from the PCL range.

The PCL range where the GSM channel is locked in step S302 may be determined in a list manner, for example, a list is set, where the list includes PCL ranges corresponding to all GSM channels, and after the GSM channel is determined, the PCL range can be obtained by directly looking up a table. For example, for GSM850/900, the PCL legal range is 5-19, where 5 represents the maximum power level; for GSM1800/1900, the legal range of PCL is 0-15, wherein 0 represents the maximum power level.

Step S303, the electronic device transmits a signal on the GSM channel by using the maximum power value corresponding to the maximum power level.

Step S304, the electronic device maintains the GSM channel and the maximum power value transmitting signal, and tests the interference of the GSM channel to the functional module.

The implementation method of the step S304 may specifically be:

the electronic device maintains the GSM channel and the maximum power value, selects a plurality of functional modules with frequency points from all the functional modules, singly starts the functional modules in sequence (the sequence can be set by a user, and can be a fixed sequence), tests the interference of the GSM channel to each functional module, such as interference, and records the functional module generating the interference in an interference list.

Optionally, the interference list may specifically include: the name of the functional module generating interference and the corresponding GSM channel, for example, the MIPI frequency of the display screen and the channel number 41 of GSM generate interference, and then the display screen and GSM 41 can be recorded in the interference list. Of course, the above expression may also be expressed in other manners, for example, it may be represented by a character string, and specifically, for example, the module that generates the interference includes: each module corresponds to 1 bit, 1 can represent that interference is generated, 0 represents that no interference is generated, then n bits can be set in front to represent a GSM channel, for example, 6 bits, namely, a combination mode of n bits and module bits is adopted to represent whether interference is generated or not. Specifically, for example, 1010010010, where 101001 denotes the GSM channel 41, 0010 denotes that the module corresponding to the 3 rd bit generates interference, that is, the display screen generates interference, this expression is merely an example, and in a specific implementation, other expressions, such as a bitmap expression, may also be used.

According to the technical scheme, the interference is automatically detected through the electronic device, so that the detection method can realize the simultaneous detection of multiple devices, and because other devices are not needed to be matched, whether the local control per se interferes with other modules or not is completely controlled, the realization of interference detection of massive devices can be supported, the occurrence of interference phenomenon of the outgoing mobile phone is avoided, and the user experience degree is further improved.

Optionally, the starting the plurality of functional modules in sequence to test the interference of the GSM channel to each functional module specifically may include:

selecting a first function module in sequence, determining input data x of the first function module, collecting output data y of the first function module, comparing the output data y with the input data x to obtain a difference rate, if the difference rate is smaller than a set threshold, determining that no interference is generated, and if the difference rate is larger than the set threshold, determining that interference is generated.

Taking a display screen as an example to illustrate a specific implementation manner, as shown in fig. 4a, fig. 4a is a schematic diagram of data transmission of a display device (e.g. a liquid crystal display), and as shown in fig. 4a, digital signals output by LCD driving boards include RGB data signals, where RGB is colors representing three channels of Red, Green, and Blue, that is, three primary colors generally known as "three primary colors", where R represents Red (Red), G represents Green (Green), and B represents Blue (Blue); and also includes signals such as line synchronization (Hsync, Vsync, Vertical synchronization), Data Enable (DE, Data Enable), and pixel clock. Taking the output of the low-voltage differential signaling (LVDS) interface as an example, the arrangement of the signals is shown in fig. 4 b. Two transmission modes are defined in the LVDS transmission protocol: a Data Enable mode (DE mode, full name of Data Enable mode) and a synchronization mode (Sync mode, full name of synchronization mode); DE mode only needs the DE signal to synchronize RGB data, Sync mode needs to synchronize RGB data with Hsync and Vsync.

As shown in fig. 4b, which is a schematic diagram of the output signals of a normal display screen, as shown in fig. 4b, when the DE signal and the start signal STV are both high level, if the display screen receives no interference, the output data is substantially the same as the input data, and if interference occurs, the input data is unchanged because it is the original data, but the output data is not changed because of the interference, i.e. abnormal data, as shown in the tx interval of fig. 4c, if the STV signal is disturbed, the output data is directly zero, although in practical applications, in the tx interval, other signals may be interfered, for example, the output signal is interfered, so that it may output abnormal data, for example, the high level of the output signal is a variable value or the value of the high level is very different from the high level value of the input data, so that it can be determined that the interference occurs.

Optionally, the difference rate obtained by comparing the output data y with the input data x may specifically be:

determining the number alpha of effective values of input data x, determining the number beta of effective values of output data y, wherein the difference rate is 1-beta/alpha; the effective value may be a value in which the high level of the input data x is within a set range, and may be determined to be an ineffective value if the high level is not within the set range.

The strength of the interference of the GSM channel on the output data of the display screen can be known through statistics of the effective value quantity, if the interference is large, the effective quantity beta of the output data y is small, the corresponding difference rate is high, and whether the interference of the GSM channel exists can be directly determined according to the difference rate.

Referring to fig. 5a, fig. 5a provides an electronic device, which includes: a communication module 501, an application processor AP502, a memory 503, said AP being connected to said communication module and said memory, said memory storing one or more programs;

the AP502 is further configured to maintain the GSM channel and the maximum power value transmitting signal, and test interference of the GSM channel to the functional module.

The AP502 is further configured to select a first function module in sequence, determine input data x of the first function module, collect output data y of the first function module, compare the output data y with the input data x to obtain a difference rate, determine that no interference is generated if the difference rate is smaller than a set threshold, and determine that interference is generated if the difference rate is larger than the set threshold.

The AP502 is specifically configured to determine an effective value number α of the input data x, and determine an effective value number β of the output data y, where a difference rate is 1- β/α; the effective value may be a value in which the high level of the input data x is within a set range, and may be determined to be an ineffective value if the high level is not within the set range.

According to the method, the electronic device automatically interferes to detect, so that a plurality of devices can be simultaneously detected, and because other devices are not needed to be matched, whether the local control per se interferes with other modules or not is completely controlled, the method can support the realization of interference detection of massive devices, avoids the occurrence of interference of outgoing mobile phones, and further improves the user experience.
