[0041] It should be understood that the terms "first\second\third" involved in the embodiments of the present application are only used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0044] It should also be understood that the "correspondence" mentioned in the embodiments of the present application may indicate a direct or indirect correspondence between the two, or an association between the two, or a relationship of indication and being indicated, configuration and being configured, etc.

[0045] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application.

[0046] The network environment identification method provided in the embodiment of the present application can be as follows: Figure 2 As shown, including S101-S102, as follows:

[0047] S101: Detect the current movement state of the terminal and the quality of multi-path signals corresponding to the multi-path antennas on the terminal.

[0048] In the embodiment of the present application, multiple antennas are configured on the terminal. For example, usually the mid-high frequency band of the mobile phone will correspond to four receiving antennas to improve the network speed or signal quality under weak network conditions. The domestic mainstream frequency bands such as B41&N41 and other mid-high frequency bands will also correspond to four antennas. Figure 3 , Figure 3 A distribution diagram of 11 antennas, ANT1-11, on a mobile phone is shown.

[0049] In some embodiments, among the multiple antennas on the terminal, the physical positions of the multiple antennas used to identify shielded scenarios in enclosed spaces on the terminal can be respectively distributed in the upper edge area and the lower edge area of ​​the terminal. This is because common terminal usage postures such as holding or holding the terminal will not cause all antennas in the upper and lower edge areas of the terminal to be blocked, thereby affecting the signal quality of the blocked antennas. There is only one type of scenario in which the signal quality of multiple antennas is affected, reduced or deteriorated, that is, the mobile phone enters a shielded space, resulting in a reduction in all-round signal quality, for example, the scene where the mobile phone enters an elevator.

[0050] In this way, the multiple antennas distributed in the upper and lower edge areas of the terminal are used as antennas for identifying shielding scenes in enclosed spaces. The layout can cover the upper and lower edges of the entire mobile phone, thereby preventing misjudgment of signal shielding environments caused by common postures such as hand holding. Figure 3 The multi-way antenna for identifying shielded scenes in enclosed spaces may include ANT-3 located at the upper left corner of the upper edge of the mobile phone, ANT-4 located at the lower right corner of the lower edge of the mobile phone, ANT1 located above the left side of the upper edge of the mobile phone, and ANT8 located at the upper right corner of the upper edge of the mobile phone.

[0051] It should be noted that the upper edge area and the lower edge area in the embodiment of the present application can be predefined according to actual conditions to ensure that common terminal usage postures such as holding or holding the terminal will not cover or block the antennas in the upper edge area and the lower edge area. No specific limitation is made here.

[0052] In S101, the terminal detects the current mobile state of the terminal itself and the signal quality corresponding to each antenna in the multi-path antenna in real time, that is, detects the quality of the multi-path signal. Among them, the mobile state characterizes whether the terminal is moving quickly, and the signal quality may include parameters or indicators that characterize the quality of the antenna's transmission and / or reception signal; illustratively, the signal quality may include but is not limited to: received signal strength indicator (Received Signal Strength Indicator, RSSI), signal to noise ratio (Signal to Interference plus Noise Ratio, SINR), reference signal received quality (Reference Signal Received Quality, RSRQ), channel quality indicator (Channel Quality Indicator, CQI) and throughput One or more combinations thereof. The specific selection is made according to the actual situation, and the embodiments of the present application are not limited thereto.

[0053] For example, the current mobile state of the terminal and the quality of the multi-channel signals can be detected by low-power real-time detection in the background. It can be understood that through continuous real-time detection, the terminal can learn the changes in its own mobile state and the changes in the quality of the multi-channel signals in real time.

[0054] In some embodiments, the current mobility state of the terminal may be determined based on a time interval of cell switching of the terminal and / or a frequency of changes in positioning information of the terminal.

[0055] Among them, the time interval of cell switching and / or the frequency of change of the terminal's positioning information can be used to identify the moving speed of the terminal. Exemplarily, when the terminal detects that multiple consecutive cell switchings have occurred, and the time intervals of the consecutive cell switchings are less than or equal to the preset time interval threshold, it means that the terminal has been rapidly switching cells, and / or when the terminal detects that the GPS coordinates have been rapidly moving, it can be determined that the current moving state is that the terminal is moving rapidly.

[0056] S102: Determine whether the terminal enters a signal shielding environment in a closed space according to the movement status and the quality of the multi-path signals.

[0057] In some embodiments, when the movement status indicates that the terminal is moving quickly, it is determined that the terminal has not entered a signal shielding environment of a closed space.

[0058] Here, when the terminal is moving quickly, the frequency band of the antenna will be constantly attenuated in all directions and then reconnected. However, this scenario is obviously not a signal shielding environment in a closed space like an elevator. In order to prevent misjudgment, when the mobile state indicates that the terminal is moving quickly, it is determined that the terminal has not entered a signal shielding environment in a closed space.

[0059] In some embodiments, when the movement status indicates that the terminal is not moving quickly, it is determined whether the terminal enters a signal shielding environment in a closed space based on the quality of multi-path signals.

[0060] Here, when the mobile state indicates that the terminal is not moving quickly, it is determined whether the terminal has entered a signal shielding environment in a closed space based on the change of the quality of the multi-channel signals within a preset time window. Here, the preset time window is used to limit the time difference between the changes in the quality of the multi-channel signals. If the quality of the multi-channel signals changes within the preset time window, it can be considered that the quality of the multi-channel signals changes synchronously.

[0061] In some embodiments, the process of determining whether the terminal enters a signal shielding environment in a closed space based on the multi-path signal quality includes:

[0062] In the first standard network, if it is detected that the degradation rate of the multi-channel signal quality is greater than or equal to the preset rate threshold, and the terminal remains connected to the first standard network, it is determined that the terminal enters a signal shielding environment in a closed space.

[0063] Among them, when the terminal is connected to the first standard network, if the signal quality under the first standard network decreases, and the decrease reaches or falls below a preset threshold, it will trigger switching to the second standard network. Exemplarily, the first standard network may include a 5G network, and the second standard network may include a 4G network. Alternatively, the first standard network may include a 4G network, and the second standard network may include a 3G network. This is not specifically limited here.

[0064] If, in the first standard network, the decline rate of each signal quality of the multi-channel signal is greater than or equal to the preset rate threshold, it means that the quality of the multi-channel signal synchronization has suddenly changed. However, if the quality of the multi-channel signal does not drop to the preset threshold that triggers the network switching, the terminal will still remain connected to the first standard network. In this case, it can be determined that the terminal has entered a signal shielding environment in a closed space, such as entering an elevator.

[0065] In some embodiments, the process of determining whether the terminal enters a signal shielding environment in a closed space based on the multi-path signal quality includes:

[0066] In the first standard network, if it is detected that the degradation rate of the multi-path signal quality is less than the preset rate threshold, it is determined that the terminal has not entered the signal shielding environment of the closed space.

[0067] That is, in the first standard network, if the degradation rate of the multi-channel signal quality is less than the preset rate threshold, it means that the multi-channel signal quality has not deteriorated in all directions. Therefore, it can be determined that the terminal has not entered the signal shielding environment of the enclosed space.

[0068] In some embodiments, the process of determining whether the terminal enters a signal shielding environment in a closed space based on the multi-path signal quality includes:

[0069] If it is detected that the terminal switches from a first-standard network to a second-standard network, then in the second-standard network, it is determined whether the rate of decrease in the quality of multiple signals is greater than or equal to a preset rate threshold; if the rate of decrease in the quality of multiple signals in the second-standard network is greater than or equal to the preset rate threshold, it is determined that the terminal has entered a signal shielding environment in a closed space.

[0070] Among them, if the quality of multiple signals in the first-standard network continues to deteriorate until it reaches or falls below the preset threshold for triggering network switching, the terminal will switch from the first-standard network to the second-standard network. In the second-standard network, detect whether the rate of decrease in the quality of multiple signals is greater than or equal to the preset rate threshold. If the rate of decrease in the quality of multiple signals in the second-standard network is greater than or equal to the preset rate threshold, it means that after the terminal switches to the second-standard network due to the deterioration of signal quality, the antenna signal quality in all directions continues to deteriorate, that is, the signal quality in both the first-standard network and the second-standard network is very poor. In this case, it can be determined that the terminal has entered a signal shielding environment in a closed space, such as entering an elevator.

[0071] In some embodiments, in the second-standard network, after determining whether the rate of decrease in the quality of multiple signals is greater than or equal to a preset rate threshold, it can also be determined that the terminal has not entered a signal shielding environment in a closed space if it is detected that the rate of decrease in the quality of multiple signals in the second-standard network is less than the preset rate threshold.

[0072] Here, after switching from the first-standard network to the second-standard network, if the rate of decrease of the multi-channel signal quality in the second-standard network is less than the preset rate threshold, it means that only the signal quality in the first-standard network is poor, and the signal quality in the second-standard network is normal. At this time, it is determined that the terminal has not entered the signal shielding environment of the enclosed space.

[0073] In some embodiments, the process of determining whether the terminal enters a signal shielding environment in a closed space based on the multi-path signal quality includes:

[0074] In the second standard network, if it is detected that the degradation rate of the multi-path signal quality is greater than or equal to a preset rate threshold, it is determined that the terminal enters a signal shielding environment of a closed space.

[0075] In some embodiments, the process of determining whether the terminal enters a signal shielding environment in a closed space based on the multi-path signal quality includes:

[0076] In the second standard network, if it is detected that the degradation rate of the multi-path signal quality is less than the preset rate threshold, it is determined that the terminal has not entered the signal shielding environment of the closed space.

[0077] That is, when the terminal is connected to the second standard network, if it is detected that the rate of decrease of the multi-path signal quality is greater than or equal to the preset rate threshold, it is determined that the terminal has entered a signal shielding environment in a closed space, such as entering an elevator. If the rate of decrease of the multi-path signal quality is less than the preset rate threshold, it is determined that the terminal has not entered a signal shielding environment in a closed space.

[0078] It can be understood that the embodiments of the present application can combine the multi-channel signal quality corresponding to the multi-channel antenna of the terminal's current mobile state to determine whether the terminal has entered a signal shielding environment in a closed space, thereby achieving detection of the shielding environment without relying on additional hardware such as sensors, thereby improving the breadth and practicality of shielding scene recognition.

[0079] In practical application scenarios, this application provides a network environment identification method, such as Figure 4 As shown. The terminal performs low-power state detection in the background. When it is found that the cell has been switching rapidly or the GPS coordinates have been moving rapidly, it is judged as a rapid movement state. At this time, it will be locked and judged as a non-elevator scene to avoid misjudgment. If it is judged as a non-rapid movement state, continue to detect. At this time, there will be 5G and 4G judgments. First, 5G. When the 5G signal quality drops but does not reach the threshold, if the connected Band (such as N41) has four RSSI mutations at the same time, it is recognized as entering the elevator scene, otherwise it is a non-elevator scene. When the threshold is further reduced to 4G, if the connected Band (such as B41) still has four RSSI mutations at the same time in the 4G state, it is also recognized as entering the elevator scene, otherwise it is a non-elevator scene; if the terminal has been in 4G state, if it is recognized that the connected Band (such as B41) has four RSSI mutations at the same time, it is recognized as entering the elevator scene, otherwise it is a non-elevator scene.

[0080] It can be understood that the embodiments of the present application provide a complete solution for signal shielding environment recognition in enclosed spaces, such as elevator scene recognition, and take into account how to eliminate misjudgments caused by rapid movement, as well as different judgment strategies under the 5G and 4G standards. It utilizes the signal quality of current mainstream RF antenna signal design resources and does not require additional sensor hardware costs, thereby improving the breadth and practicality of shielding scene recognition.

[0081] The present application embodiment provides a network environment identification device 1, such as Figure 5 As shown, including:

[0090] In some embodiments, the determination module 12 is further configured to determine, in a second standard network, that the terminal has entered a signal shielding environment in a closed space if it is detected that the rate of decrease in the quality of the multi-path signals is greater than or equal to a preset rate threshold.
