This operation transforms the data or maintains it at locations in the computer's memory system, which may be reconfigured or otherwise altered in a manner well known to those skilled in the art. The data maintains a data structure that is a physical location of the memory that has particular characteristics defined by the data format. However, while the principles of the invention have been described in language specific to above, it is not intended to be limited to the specific form set forth herein, but on the contrary, it is to be understood that various steps and operations described hereinafter may be implemented in hardware.
The principles of the present invention are operational with numerous other general purpose or special purpose computing, communication environments or configurations.

The details will be described below separately.
The embodiment will be described in terms of a channel switching device, which may be specifically integrated in a terminal, where the terminal may be an electronic device with network function, such as a mobile interconnection network device (e.g., a smart phone, a tablet computer).
A method of channel switching, comprising: receiving a time acquisition instruction, acquiring current time according to the time acquisition instruction, judging whether the current time is within a preset time range, if so, judging whether a wireless local area network of the terminal is in a closed state, and if not, switching the wireless local area network to the closed state.
The present embodiment will be described from the perspective of a channel switching apparatus, which may be specifically integrated in a terminal.
Referring to fig. 1, fig. 1 is a schematic flow chart of a channel switching method according to an embodiment of the present invention, where the channel switching method according to the embodiment includes:
and step S101, acquiring the current signal intensity value of the terminal.
In the embodiment of the present invention, the terminal receives a signal sent by a base station to complete a communication function, where the base station may be a base station of a wireless local Area network (lan) based on wireless fidelity (wifi) (wireless fidelity) standard, may be a base station of a global System for Mobile communication (gsm), or may be a base station of bluetooth. The terminal transmits and receives various types of data based on wireless communication controlled by the base station. For example, a terminal may receive content data from a content distribution server via a base station, and may transmit and receive e-mails to and from another terminal. The content data may include, among others, music data such as music, radio, and the like, visual data such as moving pictures, television programs, videos, photographs, and the like, and any other data such as games, software, and the like.
The main function of the base station is to provide wireless coverage, i.e. to enable wireless signal transmission between a wired communication network and a wireless terminal. Therefore, the position of the base station in the communication network is shown in fig. 2, the control signaling, voice call or data service information on the core network side is sent to the base station through the transmission network (in 2G and 3G networks, the signal is first sent to the base station controller and then to the base station), the signal is processed by the baseband and the radio frequency on the base station side, and then sent to the antenna through the radio frequency feeder line for transmission, the terminal receives the radio wave transmitted by the antenna through the radio channel, and then demodulates the signal belonging to itself.
When the terminal receives a wireless signal transmitted from the base station, the terminal measures the signal strength of the wireless signal. The terminal may measure the signal strength of the wireless signal in various ways, for example, the AP queries moden about signal parameter information of the current terminal, where the signal parameter information may include information such as a network format (e.g., a GSM format), a frequency band (e.g., B8), a channel (e.g., ch37), and a signal strength (e.g., -98 dBm).
And step S102, determining a target device in the terminal currently in a working state.
There may be various methods for acquiring the target device currently in the operating state in the terminal. For example, devices which can cause interference to terminal signals when the terminal works, such as a camera, a display screen, a flash lamp and the like, are predetermined to obtain a set, and then whether the devices in the set are currently in a working state is respectively judged, and if so, the devices are determined to be target devices.
In other embodiments, all the devices in the terminal in the operating state may also be obtained to obtain a set, and considering that not all the operating devices in the terminal may interfere with the signal strength of the terminal, it is necessary to further determine the target device in the set.
Step S103, determining whether a difference between the current signal intensity value and a preset signal intensity value of the target device is smaller than a preset difference, if so, executing step S104, and if not, ending the process.
Before judging whether the difference value between the current signal intensity value and the preset signal intensity value of the target device is smaller than the preset difference value, the preset signal intensity value of the target device is obtained. In the embodiment of the present invention, the preset signal strength values respectively corresponding to the plurality of preset devices may be preset, and then the corresponding preset signal strength values may be determined according to the identifier of the target device.
The preset signal strength values respectively corresponding to the preset devices are the minimum signal strength value of the terminal under the interference of the preset devices, namely the signal strength value under the maximum interference of the devices. Specifically, when the preset device works, a signal intensity value of a certain preset time period is obtained, and then the minimum value of the signal intensity within the time period is taken, that is, the preset signal intensity value corresponding to the device is obtained. It should be noted that, in the process of measuring the signal strength when a certain preset device works, other devices may be kept in the off state to avoid the measurement result from errors caused by signal interference caused by other devices. For example, the measurement is performed for the front-facing camera, the front-facing camera of the terminal may be turned on, other preset devices in the terminal are turned off, and then the limit (minimum) signal intensity value after the terminal is interfered within a period of time is measured to be-100 dBm, that is, the preset signal intensity value corresponding to the front-facing camera is measured to be-100 dBm.
And judging whether the difference value between the current signal intensity value and the preset signal intensity value of the target device is smaller than a preset value, if so, determining that the influence of the target device is larger, starting a channel replacement strategy, namely executing the step S104, and if not, ending the current process.
And step S104, switching the channel currently used by the terminal to a standby channel.
Specifically, the terminal may generate a channel switching instruction and send the channel switching instruction to the base station currently connected to the terminal, and then the base station reallocates a channel to the terminal according to the instruction. In the embodiment of the present invention, the base station may reallocate the channel for the terminal by modifying the RX report value, where the RX report value refers to that the intelligent terminal reports a specific value to the base station according to the received signal strength after receiving the transmission signal of the base station, and the specific value reported is referred to as the RX report value. And the base station acquires the signal quality of the terminal through the RX return value returned by the terminal, and the channel is allocated to the terminal again when the signal quality is poor.
It should be noted that, after the base station reallocates the channel to the terminal, the steps S101 to S104 may be repeated until the terminal is switched to the optimal channel, where the optimal means that the signal strength of the terminal is minimally affected when the internal device of the terminal operates under the current channel.
As can be seen from the above, the channel switching method provided in the embodiment of the present invention first obtains the current signal strength value of the terminal, determines the target device currently in the working state in the terminal, determines whether a difference between the current signal strength value and the preset signal strength value of the target device is smaller than a preset difference, and switches the channel currently used by the terminal to the standby channel if the difference is smaller than the preset difference. According to the scheme, the influence degree of a device in the terminal on the terminal signal is judged according to the current channel signal strength value, if the influence exceeds a certain degree, an instruction is sent to enable the corresponding base station to switch the channel currently used by the terminal to the standby channel, the interference of the terminal to an internal radio frequency system can be reduced, and therefore the signal strength and the user experience are improved.
In the above description, the channel switching method of the present invention will be described in specific embodiments.
Referring to fig. 3, fig. 3 is a schematic flow chart of another channel switching method according to an embodiment of the present invention, which is described by taking a smart phone as an example, and includes:
step S201, acquiring feature information of the mobile phone when the preset device works, where the feature information includes a minimum signal strength value of the mobile phone within a preset time period and is determined as a preset signal strength value.
In the embodiment of the present invention, the characteristic information may further include information such as a network type, a frequency band, and a channel, for example, the preset device is a front-facing camera, the type is GSM, the frequency band is B8, and the interference channel ch37, and the interference degree is-100 dBm after being interfered. The preset device is a device which can interfere with a mobile phone signal during working and can comprise a display screen, a charge pump, a camera, a flash lamp, a light sensing module, a fingerprint film group and the like.
In addition, in practical applications, some special network standards adopt fixed channels in cells, and channels cannot be changed, for example, each cell of four networks, TD _ SCDMA, CDMA2000, WCDMA, and LTE, adopts fixed channels, and cannot be changed. Therefore, a preset network system set can be preset, including the preset network system, and if it is determined that the network system currently used by the mobile phone is not the preset network system, the method further obtains the feature information of the mobile phone, that is, before obtaining the current signal strength value of the mobile phone, the method may further include:
acquiring a network system currently used by the mobile phone;
judging whether the network standard is a preset network standard or not;
if not, executing the step of obtaining the current signal intensity value of the mobile phone.
Step S202, generating a feature information set according to the feature information respectively corresponding to the plurality of preset devices.
For example, network systems, frequency bands, channels and preset signal strength values respectively corresponding to the display screen, the charge pump, the camera, the flash lamp, the light sensing module and the fingerprint module are obtained, as shown in fig. 4. It should be noted that, when the above data is measured, interference needs to be eliminated for the hardware and structural mode of the mobile phone, so that the accuracy of the measured data is increased.
Step S203, acquiring a current signal strength value of the mobile phone.
When the handset receives a wireless signal transmitted from the base station, the handset measures the signal strength of the wireless signal. The mobile phone may have a plurality of ways to measure the signal strength of the wireless signal, for example, the AP queries moden about the signal parameter information of the current mobile phone, where the signal parameter information may include information such as a network system (e.g., a GSM system), a frequency band (e.g., B8), a channel (e.g., ch37), and a signal strength (e.g., -98 dBm).
And step S204, acquiring a preset device set according to the characteristic information set.
For example, the preset device set obtained according to the feature information set is a display screen, a charge pump, a camera, a flash lamp, a light sensing module, and a fingerprint module.
Step S205, determining a target device currently in an operating state in a preset device set.
Specifically, the current states of the preset devices may be obtained, and if the current states are working states, the preset devices are determined as target devices.
And step S206, acquiring a preset signal intensity value corresponding to the target device according to the characteristic information set.
Step S207, determining whether a difference between the current signal strength value and a preset signal strength value of the target device is smaller than a preset difference, if so, executing step S208, and if not, ending the process.
For example, the AP queries moden for the frequency band, channel (e.g., GSM standard, B8, ch37) and signal strength of the current handset. Judging whether the difference between the signal intensity of the current channel and the maximum RSSI after the current channel is interfered is less than 6dB (for example, when the signal intensity is-98 dBm, the difference between the signal intensity and-100 dBm is 2dB), if the difference is less than 6dB, determining that the influence of the target device is large, starting a channel replacement strategy, and if the difference is not less than 6dB, ending the flow.
Step S208, generating a channel switching instruction, and modifying the signal intensity feedback value according to the channel switching instruction.
Step S209, sending the modified signal strength feedback value to the base station connected to the mobile phone, so that the base station reallocates the channel to the mobile phone according to the signal strength feedback value.
The mobile phone receives the base station channel, and reports the current mobile phone channel strength and signal quality to the base station, the channel switching strategy is to change the reported signal quality, when the channel switching strategy is started, the reported signal quality is changed to be the worst, and the base station actively redistributes the channel to the mobile phone after receiving the instruction of poor signal quality.
As can be seen from the above, the channel switching method provided in the embodiment of the present invention first obtains feature information of a mobile phone when a preset device operates, where the feature information includes a minimum signal intensity value of the mobile phone within a preset time period and is determined as a preset signal intensity value, generates a feature information set according to feature information respectively corresponding to a plurality of preset devices, obtains a current signal intensity value of the mobile phone, obtains the preset device set according to the feature information set, determines a target device currently in an operating state in the preset device set, obtains the preset signal intensity value corresponding to the target device according to the feature information set, determines whether a difference between the current signal intensity value and the preset signal intensity value of the target device is smaller than a preset difference, if so, generates a channel switching instruction, modifies a signal intensity feedback value according to the channel switching instruction, and sends the modified signal intensity feedback value to a base station connected to the mobile phone, so that the base station reallocates the channel for the mobile phone according to the signal strength feedback value. According to the scheme, the influence degree of a device in the terminal on the terminal signal is judged according to the current channel signal strength value, if the influence exceeds a certain degree, an instruction is sent to enable the corresponding base station to switch the channel currently used by the terminal to the standby channel, the interference of the terminal to an internal radio frequency system can be reduced, and therefore the signal strength and the user experience are improved.
