With the development of communication technology, 5G has become a hot spot in the field of communication research and development. In the early stage of 5G deployment, in order to save costs and quickly carry out business, most operators choose non-standalone (NSA) mode. NSA is a networking mode of 5G network. NSA only transforms the existing 4G network. The activation method is relatively simple. It can seamlessly inherit all the services, interfaces, and architectures of the existing network. 4G and 5G have unified network management and convenient operation and maintenance. It must rely on the existence of 4G network.

Due to the cost of the 5G core network and other issues, a common architecture for NSA networking is: 4G base station as the primary station and 5G base station as the secondary station. Under this architecture, a dual connection will be established with the 4G base station as the primary station and the 5G base station as the secondary station. Therefore, it is also called EN-DC (E-UTRA-NR Dual Connectivity), which is a dual connection between the LTE network and the NR (New Radio, new access technology) network, where the NR network refers to the 5G network mode.

Currently, terminal devices can establish NSA 5G network connection (i.e. adding ENDC) in any frequency band and any scenario. Since NSA 5G relies on 4G network, after the terminal device is connected to NSA 5G, 4G and 5G will share the terminal device's antenna.

After practice and careful research, the inventors of this application found that some mobile terminals have hardware defects. This hardware defect causes the LTE signal to become weaker after adding ENDC in some 4G frequency bands (for example, LTE Band 3). For example, after adding ENDC, in some 4G frequency bands, LTE cannot use the side antenna and can only use the top and bottom antennas. If certain holding methods are used, after adding ENDC (for example, connecting to the 4G network through Band 3 and connecting to the 5G network through N41), the LTE signal strength of the terminal device will mutate (about 8db drop when holding with both hands, and about 5db drop when holding with one hand). Among them, LTE (LongTerm Evolution, long-term evolution of the UMTS technical standard developed by the 3GPP organization) represents 4G; Band represents the frequency band. When a terminal device registers to the network, it needs to select a frequency band for registration, which is divided according to the frequency.

Since the LTE signal becomes weak, it is very easy to cause 4G cell switching. When a cell switching occurs, the current network of the terminal device will be disconnected, resulting in unstable network signals, which will cause high latency, interruptions, etc., and lead to poor user experience. After the cell switching, ENDC will be released and the LTE signal will become strong again; if ENDC is added again, and the 4G frequency band is still the frequency band where the LTE signal strength weakened after adding ENDC, cell switching will occur again; this will result in frequent switching of cells, making the network signal more unstable, further reducing the user experience.

In order to improve the above problems, the embodiments of the present application provide a method, apparatus, terminal device and readable storage medium for improving signal stability. The embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

Please refer to FIG. 1, which is a block diagram of a terminal device 100 provided in an embodiment of the present application. The terminal device 100 may be, but is not limited to, a smart phone, a tablet computer, etc. The terminal device may include a memory 110, a processor 120, and a communication unit 130. The memory 110, the processor 120, and the communication unit 130 are electrically connected to each other directly or indirectly to achieve data transmission or interaction. For example, these components may be electrically connected to each other via one or more communication buses or signal lines.

The memory 110 is used to store programs or data. The memory 110 may be, but is not limited to, a random access memory (RAM), a read only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), etc.

The processor 120 is used to read/write data or programs stored in the memory 110 and execute corresponding functions. For example, the memory 110 stores a signal stability improvement device 200, and the signal stability improvement device 200 includes at least one software function module that can be stored in the memory 110 in the form of software or firmware. The processor 120 executes various functional applications and data processing by running software programs and modules stored in the memory 110, such as the signal stability improvement device 200 in the embodiment of the present application, that is, realizing the signal stability improvement method in the embodiment of the present application.

The communication unit 130 is used to establish a communication connection between the terminal device 100 and other communication terminals through a network, and to send and receive data through the network.

It should be understood that the structure shown in FIG1 is only a schematic diagram of the structure of the terminal device 100, and the terminal device 100 may also include more or fewer components than those shown in FIG1, or have a configuration different from that shown in FIG1. Each component shown in FIG1 may be implemented by hardware, software, or a combination thereof.

Please refer to Figure 2, which is one of the flow diagrams of the signal stability improvement method provided in the embodiment of the present application. The method can be applied to the above-mentioned terminal device 100. The specific flow of the method is described in detail below by taking the application of the method to the terminal device 100 as an example. The method may include step S130 and step S140.

Step S130, determining whether the 4G frequency band currently used by the terminal device belongs to the preset frequency band.

In this embodiment, the specific 4G frequency band corresponding to the preset frequency band may be pre-stored, for example, LTE Band 3. The preset frequency band is the frequency band where the 4G signal is weakened when the terminal device adds ENDC, that is, when the 4G frequency band used by the terminal device is a frequency band belonging to the preset frequency band, the 4G signal strength will become weaker. The 4G frequency band currently used by the terminal device, that is, the 4G frequency band currently resident by the terminal device may be obtained in accordance with timing or other triggering methods. Then, the 4G frequency band currently used by the terminal device may be compared with the specific 4G frequency band corresponding to the preset frequency band to determine whether the 4G frequency band currently used is the same as the specific 4G frequency band corresponding to one of the preset frequency bands. If the same, it can be determined that the 4G frequency band currently used belongs to the preset frequency band; if the 4G frequency band currently used is different from each of the specific 4G frequency bands corresponding to the preset frequency band, it can be determined that the 4G frequency band currently used does not belong to the preset frequency band.

If the currently used 4G frequency band does not belong to the preset frequency band, ENDC may not be disabled and the operation may continue in the conventional manner. For example, when the currently used 4G frequency band does not belong to the preset frequency band, it can be considered that in this case, even if ENDC is added to the terminal device, the 4G signal will not become weak, so it can still be processed in the conventional manner, wherein the conventional manner is to add ENDC.

If the currently used 4G frequency band belongs to the preset frequency band, it means that in this case, if the terminal device adds ENDC, the 4G signal will become weak, and then cell switching will occur, resulting in unstable signal of the terminal device. Therefore, when the currently used 4G frequency band belongs to the preset frequency band, step S140 is executed.

Step S140, prohibiting the addition of ENDC.

In this embodiment, when it is determined that the 4G frequency band currently used by the terminal device belongs to the preset frequency band, if the terminal device has not yet added ENDC, the terminal device can be controlled to stop reporting 5G measurement data to prevent the base station from establishing a 5G connection for the terminal device based on the 5G measurement data. The 5G measurement data may include information such as the frequency and signal strength of the 5G cell. If the terminal device has currently added ENDC, the terminal device can be controlled to disconnect the 5G connection and stop reporting the 5G measurement data.

Optionally, the terminal device may include a Qualcomm baseband chip. When it is determined that the addition of ENDC needs to be prohibited, a command to prohibit the connection of ENDC may be sent to the Qualcomm baseband chip. After receiving the command, the Qualcomm baseband chip will no longer report 5G measurement data to the base station, and if the terminal device currently has a 5G connection, it will be disconnected immediately.

The embodiment of the present application identifies whether the 4G frequency band currently used by the terminal device belongs to the preset frequency band, and blocks the establishment of an ENDC connection when the 4G frequency band currently used belongs to the preset frequency band. By prohibiting the addition of ENDC, it is possible to avoid the situation where the 4G signal becomes weak after the terminal device adds ENDC when the 4G frequency band currently used by the terminal device belongs to the preset frequency band, thereby avoiding the situation where 4G cell switching or even frequent switching occurs, thereby improving signal stability and improving user experience.

5G has a fast transmission speed. If the addition of ENDC is prohibited as long as the 4G frequency band currently used by the terminal device belongs to the preset frequency band, some applications that do not require continuous network or applications that do not require continuous network use in some cases may not be able to use the 5G network. To avoid this situation, it can be determined whether to prohibit the addition of ENDC based on the current foreground application of the terminal device.

Optionally, as an optional implementation, the current usage scenario of the terminal device can be identified, and based on the current usage scenario and preset conditions, it can be determined whether the current scenario is a scenario that requires a continuous network. If necessary, step S140 is executed: adding ENDC is prohibited. For example, the current usage scenario is using the WeChat application to make a WeChat call, and the preset conditions include prohibiting the addition of ENDC when using a WeChat call. In this scenario, adding ENDC can be prohibited to ensure signal stability.

Optionally, as another optional implementation, it is also possible to determine whether to execute step S140 directly based on the current foreground application of the terminal device. Please refer to Figure 3, which is a second flow chart of the signal stability improvement method provided in an embodiment of the present application. Before step S140, the method may further include step S120. Optionally, step S120 and step S130 may be executed simultaneously, or step S120 or step S130 may be executed first, and the specific execution order is not limited here.

Step S120, determining whether the type of the current foreground application is a preset type.

Among them, the preset type is an application type that requires continuous use of the network. Applications that require continuous use of the network will experience high latency or even interruption when the signal of the terminal device is unstable. To avoid this phenomenon, the embodiment of the present application may prohibit the addition of ENDC when the type of the current foreground application of the terminal device is a preset type and the currently used 4G frequency band belongs to the preset frequency band. In this way, it can be ensured that some applications can still use 4G and 5G networks, and at the same time, it can be avoided that the addition of ENDC in the preset frequency band causes applications that require signal stability to experience unstable signals when using the network.

Optionally, as an optional implementation, the application type of the current foreground application can be determined based on the application information of the current foreground application. The application information can be the description information of the current foreground application, such as the application package name. Then, the application type of the current foreground application is compared with the preset type to determine whether the type of the current foreground application is the preset type. In this way, the setting of the preset type can be quickly completed, and the preset type can be set according to actual needs, such as a live broadcast type APP, or a game type APP.

Optionally, as another optional implementation, various preset application identifiers are pre-saved. When determining whether the type of the current foreground application is a preset type, the application identifier of the current foreground application can be obtained. Among them, the application identifier is a unique identifier used to represent the application, that is, the application identifiers of different applications are different, and the application identifier can be, but not limited to, the application package name. In the case of obtaining the application identifier of the current foreground application, the application identifier of the current foreground application is compared with each preset application identifier. If the application identifier of the current foreground application is the same as a preset application identifier, it is determined that the type of the current foreground application is the preset type; if the application identifier of the current foreground application is different from each preset application identifier, that is, the application identifier of the current foreground application is different from each preset application identifier, it can be determined that the type of the current foreground application is not the preset type. In this way, specific applications that do not use unstable networks can be flexibly set according to needs.

Optionally, each preset application identifier may include an application identifier of an application with a high delay requirement. Each preset application identifier may include a preset game application identifier and/or a preset live broadcast application identifier, for example, including an application identifier of a game application-Honor of Kings and an application identifier of a live broadcast application-Tik Tok. Thus, the user's gaming experience and/or live broadcast experience can be improved.

If the current foreground application type is continuously determined to be a preset type, more power consumption will be wasted. To avoid this situation, please refer to FIG. 4 , which is a flow chart of the third method for improving signal stability provided in an embodiment of the present application. Before step S120, the method may further include step S110.

Step S110, monitoring whether the foreground application changes.

Optionally, after the terminal device is turned on, it is possible to monitor whether the foreground application of the terminal device changes. If it changes, the changed foreground application is used as the current foreground application and step S120 is executed. If it does not change, it is possible to be in a waiting state and continue to monitor.

It is understandable that in the above scheme, if the type of the current foreground application of the terminal device is a preset type and the currently used 4G frequency band belongs to the preset frequency band, then adding ENDC is prohibited, thereby avoiding frequent cell switching during the user's use of the current foreground application, affecting the user experience. If the foreground application changes again after a period of time, and the type of the changed foreground application is not the preset type, it can be restored to the normal state, that is, ENDC is no longer disabled.

Optionally, the base station may also execute the above method to determine whether to establish a 5G connection for the terminal device. When the base station executes the above method, it may obtain the required information, such as the application identifier of the current foreground application of the terminal device, by communicating with the terminal device.

In order to execute the corresponding steps in the above-mentioned embodiments and various possible methods, a method for implementing a signal stability improving device 200 is given below. Optionally, the signal stability improving device 200 can adopt the device structure of the terminal device 100 shown in Figure 1 above.

The processing module 220 is used to prohibit adding ENDC when the currently used 4G frequency band belongs to the preset frequency band.

In an optional implementation, before prohibiting the addition of ENDC, the judgment module 210 is further used to: determine whether the type of the current foreground application is a preset type, wherein the preset type is an application type that requires continuous use of the network; when the type of the current foreground application is a preset type and the currently used 4G frequency band belongs to the preset frequency band, the processing module prohibits the addition of ENDC.

In an optional implementation, the judgment module 210 is specifically used to: compare the application identifier of the current foreground application with each preset application identifier; when the application identifier of the current foreground application is the same as a preset application identifier, determine that the type of the current foreground application is the preset type; when the application identifier of the current foreground application is different from each preset application identifier, determine that the type of the current foreground application is not the preset type.

In an optional implementation, each preset application identifier includes a preset game application identifier and/or a preset live broadcast application identifier.

In an optional implementation, before determining whether the type of the current foreground application is a preset type, the determination module 210 is further used to: monitor whether the foreground application changes; when the foreground application changes, determine whether the type of the current foreground application is a preset type, wherein the current foreground application is the foreground application after the change.

In an optional implementation, the processing module 220 is specifically used to: when ENDC has not been added currently, stop reporting 5G measurement data; when ENDC has been added currently, disconnect the 5G connection and stop reporting 5G measurement data.

Optionally, the above modules can be stored in the memory 110 shown in FIG. 1 in the form of software or firmware or solidified in the operating system (OS) of the terminal device 100, and can be executed by the processor 120 in FIG. 1.

Therefore, by prohibiting the addition of ENDC in the 4G frequency band belonging to the preset frequency band, the situation of switching 4G cells after adding ENDC in the preset frequency band can be avoided, thereby improving signal stability.
