[0021] As cellular networks have evolved from 4G LTE and NSA to 5G SA, dual-SIM UEs have also evolved their DDS and nDDS capabilities. Both DDS and nDDS can support the transition from the previous NSA to 5G SA modes. Upgrading to 5G SA can provide better performance for data services (higher throughput and lower latency). However, for dual-SIM UEs, considering that the nDDS daughter card is mainly used for voice calls, some issues may arise if the nDDS daughter card is in 5G SA mode. In 5G SA mode, voice options include EPS Fallback (an initial phase solution) and VoNR (voice over NR, to be supported in later phases). Network upgrades to support VoNR will take some time. Therefore, in the early stages of 5G SA deployment, EPS Fallback will be the primary choice for voice in 5G SA. Compared to the NSA mode voice solution (VoLTE, also known as LTE voice), EPS Fallback introduces additional latency because the UE will perform a RAT change from 5G to 4G LTE to complete the voice call setup. Furthermore, after the voice call ends, the UE may need time to switch back to 5G. IRAT (Inter-Radio Access Technology) procedures can introduce significant latency (for voice call setup) / service interruptions (when switching from 4G to 5G). Furthermore, voice services involving IRAT procedures may experience stability and power consumption issues. Initial coverage of 5G SA deployments is limited. This means that UEs may frequently switch between 4G and 5G. Considering that UEs need to switch to 4G to complete voice calls regardless, this invention provides a dynamic network switching method to achieve free switching between the two network modes, which will be specifically described through the following embodiments.

[0022] refer to Figure 1 , Figure 1This is a flowchart of a network switching method according to a first embodiment of the present invention, including the following steps.

[0023] Step S11: Access the first network standard network.

[0024] Specifically, the user equipment connects to a network of the first network standard, which can be either SA (Standalone) or NSA (Non-Standalone) mode. SA mode is a type of 5G network; in SA mode, the user equipment (5G terminal) connects to the 5G base station and the 5G core network, allowing for better utilization of 5G's advantages, such as ultra-low latency. NSA mode is another 5G network mode deployed based on the current 4G base station and network architecture.

[0025] Step S12: Determine the subscription type to be executed.

[0026] The subscription type to be executed by the user equipment must be determined. The subscription type to be executed must include at least voice and data types. Specifically, whether the subscription type to be executed is a voice type can be determined based on the number of EPS Fallbacks; and whether the subscription type to be executed is a data type can be determined based on the number of SCG bearer organizations.

[0027] In one embodiment, the number of EPS Fallbacks is detected within a preset detection period. If the number of EPS Fallbacks is greater than a first preset threshold, the subscription type to be executed is determined to be a voice type. It is understood that if the number of EPS Fallbacks is less than the first preset threshold, the subscription type to be executed is determined to be a non-voice type. Whether the subscription type is a data type can be determined by the number of SCG carriers within the preset detection period. Specifically, the number of SCG carriers within the preset detection period is detected; if the number of SCG carriers is greater than a second preset threshold, the subscription type to be executed is determined to be a data type.

[0028] In one embodiment, when determining the subscription type to be executed, it may be determined whether the network maintaining access to the first network standard has ended. The subscription type to be executed is determined when it is determined that the network maintaining access to the first network standard has ended; or, the subscription type to be executed is determined after it has been determined that the network maintaining access to the first network standard has ended.

[0029] Step S13: Switch from the first network type to the second network type based on the subscription type to be executed.

[0030] Depending on the subscription type to be executed, the network connected to the user device is switched from a first network standard to a second network standard. The second network standard can be either NSA or SA mode.

[0031] It is understandable that the first network standard can be SA mode and the second network standard can be NSA mode; or, the first network standard can be NSA mode and the second network standard can be SA mode.

[0032] In one specific embodiment, assuming the first network standard is SA mode and the second network standard is NSA mode, the subscription type to be executed is determined. If the subscription type to be executed is a data type, the user device is kept in the first network standard, i.e., the SA mode network; if the subscription type to be executed is a voice type, the first network standard is switched to the second network standard, i.e., the SA mode network is switched to the NSA mode network. In one embodiment, after switching the SA mode network to the NSA mode network, the subscription type to be executed can be determined. In this case, if the subscription type to be executed is determined to be a data type, the second network standard is switched back to the first network standard, i.e., the NSA mode network is switched back to the SA mode network.

[0033] In this embodiment, after switching from SA mode to NSA mode, it is detected whether the user equipment has entered a tracking area or cell that supports VoNR. Specifically, if the user equipment enters a tracking area or cell that supports VoNR, the NSA mode network is switched to the SA mode network.

[0034] Understandably, the user equipment establishes a database that stores all tracking areas or cells that support or do not support VoNR. The user equipment uses its positioning device to detect its current cell or tracking area, compares this current location with the data stored in the database, and determines whether the cell or tracking area at its current location supports VoNR.

[0035] In another embodiment, after switching from SA mode network to NSA mode network, it is detected whether the user equipment is camped on an LTE cell that does not support NSA. If the user equipment is camped on an LTE cell that does not support NSA, then the NSA mode network is switched to SA mode network.

[0036] Understandably, the user equipment (UE) maintains a database storing all LTE cells that support NSA or all LTE cells that do not support NSA. The UE uses its positioning device to detect the cell at its current location, compares the current cell with the data stored in the database, and determines whether the cell at its current location is an NSA-supporting LTE cell.

[0037] In another embodiment, assuming the first network standard is NSA mode and the second network standard is SA mode, the subscription type to be executed is determined. If the subscription type to be executed is voice, the user device is kept in the second network standard, i.e., the SA mode network; if the subscription type to be executed is data type, the first network standard network is switched to the second network standard network, i.e., the NSA mode network is switched to the SA mode network. In one embodiment, after switching the NSA mode network to the SA mode network, the subscription type to be executed can be determined; if the subscription type to be executed is voice, the second network standard network is switched back to the first network standard network, i.e., the SA mode network is switched back to the NSA mode network.

[0038] In this embodiment, after switching the NSA mode network to the SA mode network, it is detected whether the user equipment has entered a tracking area or cell that does not support VoNR. Specifically, if the user equipment enters a tracking area or cell that does not support VoNR, the SA mode network is switched to the NSA mode network.

[0039] In one specific embodiment, the number of handovers is recorded each time a handover occurs between the first network standard and the second network standard. For example, when a user equipment switches from the first network standard to the second network standard, the handover count is recorded as 1; when a user equipment switches from the second network standard to the first network standard, the handover count is recorded as 2, and so on.

[0040] In one embodiment of the present invention, the number of switching operations is introduced as a criterion when determining the subscription type to be executed. Specifically, when the number of EPS Fallbacks is greater than a first preset threshold and the number of switching operations is less than a preset number, the subscription type to be executed is determined to be a voice type. Within a preset detection period, when the number of SCG bearer mechanisms is greater than a second preset threshold and the number of switching operations is less than a preset number, the subscription type to be executed is determined to be a data type.

[0041] The network switching method of this invention switches between SA mode and NSA mode networks based on the subscription type to be executed, enabling free switching between the two network modes. In the technical solution of this invention, the number of EPSFallbacks determines whether the subscription type to be executed is voice, and the number of SCG bearer organizations determines whether the subscription type to be executed is data type. This achieves free switching between the two network modes based on the subscription type, reducing switching difficulty, minimizing switching latency, and avoiding service interruptions.

[0042] refer to Figure 2 , Figure 2This is a flowchart of a network switching method according to a second embodiment of the present invention, including the following steps.

[0043] Step S21: Access the first network standard network.

[0044] Specifically, the user equipment connects to a first network standard, which can be either SA (Standalone) or NSA (Non-Standalone) mode. SA mode is a type of 5G network; in SA mode, the user equipment (5G terminal) connects to the 5G base station and the 5G core network, allowing for better utilization of 5G's advantages, such as ultra-low latency. NSA mode is another 5G network mode deployed based on the current 4G base station and network architecture.

[0045] Step S22: Determine the cell at the current location or the tracking area to which the cell belongs.

[0046] Specifically, after connecting the user equipment to the first network standard, the cell of the user equipment's current location or the tracking area to which the cell belongs is determined.

[0047] Step S23: Switch from the first network standard to the second network standard based on the cell or tracking area.

[0048] Specifically, if the first network standard is SA mode and the second network standard is NSA mode, when it is detected that the user equipment cell or tracking area does not support VoNR, the first network standard network is switched to the second network standard network. For example, the SA mode network is switched to the NSA mode network.

[0049] If the first network standard is NSA mode and the second network standard is SA mode, when the user equipment cell or tracking area supports VoNR, the first network standard network will be switched to the second network standard network. For example, the NSA mode network will be switched to the SA mode network.

[0050] The network handover method in this embodiment enables switching between a first network mode and a second network mode based on the user equipment's cell or tracking area. Specifically, when the user equipment's cell or tracking area does not support VoNR, the SA mode network is switched to the NSA mode network. When the user equipment's cell or tracking area supports VoNR, the NSA mode network is switched to the SA mode network. This achieves free switching between the two network modes, reduces handover difficulty and latency, and avoids service interruption.

[0051] refer to Figure 3 , Figure 3This is a schematic diagram of the structure of a network switching device according to a first embodiment of the present invention. Specifically, the network switching device 30 includes a network access module 31, a subscription determination module 32, and a network switching module 33.

[0052] The network switching module 30 supports at least two network standards, including a first network standard and a second network standard; wherein one of the first network standard and the second network standard is SA mode and the other is NSA mode.

[0053] The network access module 31 is configured to access the first network standard network. Specifically, the network access module 31 is configured to connect the user equipment to the first network standard network, which can be in SA mode or NSA mode. SA mode is a type of 5G network where the user equipment (5G terminal) connects to the 5G base station and 5G core network, better leveraging the advantages of 5G, such as ultra-low latency. NSA mode is another 5G network mode deployed based on the current 4G base station and network architecture.

[0054] The subscription determination module 32 is configured to determine the type of subscription to be executed. Specifically, the subscription determination module 32 can determine whether the subscription type to be executed is a voice type based on the number of EPS Fallbacks; and determine whether the subscription to be executed is a data type based on the number of SCG bearers. In one embodiment, within a preset detection period, the subscription determination module 32 detects the number of EPS Fallbacks; if the number of EPS Fallbacks is greater than a first preset threshold, the subscription type to be executed is determined to be a voice type; understandably, if the number of EPS Fallbacks is less than the first preset threshold, the subscription type to be executed is determined not to be a voice type. The subscription determination module 32 can determine whether the subscription type is a data type based on the number of SCG bearers within a preset detection period. Specifically, the subscription determination module 32 detects the number of SCG bearers within a preset detection period; if the number of SCG bearers is greater than a second preset threshold, the subscription type to be executed is determined to be a data type.

[0055] In one embodiment, when determining the subscription type to be executed, the subscription determination module 32 needs to determine whether the network maintaining access to the first network standard has ended. If it is determined that the network maintaining access to the first network standard has ended, the subscription determination module 32 determines the subscription type to be executed; or, if it is determined that the network maintaining access to the first network standard has ended, the subscription determination module 32 determines the subscription type to be executed.

[0056] The network switching module 33 is configured to switch from a first network standard network to a second network standard network based on the subscription type to be executed.

[0057] Specifically, assuming the first network standard is SA mode and the second network standard is NSA mode. If the subscription determination module 32 determines that the subscription type to be executed is a data type, then the user equipment remains connected to the first network standard, i.e., the SA mode network. If the subscription determination module 32 determines that the subscription type to be executed is a voice type, then the network switching module 33 switches the first network standard network to the second network standard network, i.e., the network switching module 33 switches the SA mode network to the NSA mode network. In one embodiment, after the network switching module 33 switches the SA mode network to the NSA mode network, the subscription determination module 32 can determine the subscription type to be executed. If the subscription determination module 32 determines that the subscription type to be executed is a data type, then the network switching module 33 switches the second network standard network back to the first network standard network, i.e., the network switching module 33 switches the second network standard network back to the first network standard network. In other words, the network switching module 33 switches the NSA mode network back to the SA mode network.

[0058] In this embodiment, after switching from SA mode to NSA mode, the network switching module 33 uses the subscription determination module 32 to detect whether the user equipment has entered a tracking area or cell that supports VoNR. Specifically, if the user equipment enters a tracking area or cell that supports VoNR, the network switching module 33 switches from NSA mode to SA mode.

[0059] In this embodiment, after the network switching module 33 switches the SA mode network to the NSA mode network, the subscription determination module 32 is used to detect whether the user equipment is camped on an LTE cell that does not support NSA. If the user equipment is camped on an LTE cell that does not support NSA, the network switching module 33 switches the NSA mode network to the SA mode network.

[0060] Specifically, assuming the first network standard is NSA mode and the second network standard is SA mode, the subscription determination module 32 determines the subscription type to be executed. If the subscription type to be executed determined by the subscription determination module 32 is a voice type, the user equipment is kept in the second network standard, i.e., the SA mode network. If the subscription type to be executed determined by the subscription determination module 32 is a data type, the network switching module 33 switches the first network standard network to the second network standard network, that is, the network switching module 33 switches the NSA mode network to the SA mode network. In one embodiment, after the network switching module 33 switches the NSA mode network to the SA mode network, the subscription determination module 32 can determine the subscription type to be executed; if the subscription type to be executed is a voice type, the network switching module 33 switches the second network standard network back to the first network standard network, that is, the network switching module 33 switches the SA mode network back to the NSA mode network.

[0061] In this embodiment, after the network switching module 33 switches the network from NSA mode to SA mode, the subscription determination module 32 detects whether the user equipment has entered a tracking area or cell that does not support VoNR. Specifically, if the user equipment enters a tracking area or cell that does not support VoNR, the network switching module 33 switches the network from SA mode to NSA mode.

[0062] In one specific embodiment, the network switching module 33 can also record the number of switches each time a switch occurs between the first network standard network and the second network standard network. For example, when the network accessed by the user equipment switches from the first network standard network to the second network standard network, the network switching module 33 records the number of switches as 1; when the network accessed by the user equipment switches from the second network standard network to the first network standard network, the network switching module 33 records the number of switches as 2, and so on.

[0063] In one embodiment of the present invention, when the subscription determination module 32 determines the subscription type to be executed, the number of switching operations is introduced as a determination criterion. Specifically, when the subscription determination module 32 determines that the number of EPS Fallback operations is greater than a first preset threshold, and the number of switching operations recorded by the network switching module 33 is less than a preset number, the subscription type to be executed is determined to be a voice type. Within a preset detection period, when the subscription determination module 32 determines that the number of SCG bearer mechanisms is greater than a second preset threshold, and the number of switching operations recorded by the network switching module 33 is less than a preset number, the subscription type to be executed is determined to be a data type.

[0064] The network switching device in this embodiment switches between SA mode and NSA mode networks based on the subscription type to be executed, enabling free switching between the two network modes. In the technical solution of this invention, the number of EPS Fallbacks determines whether the subscription type to be executed is voice, and the number of SCG bearer organizations determines whether the subscription type to be executed is data type. This achieves free switching between the two network modes based on the subscription type, reduces switching difficulty, reduces switching latency, and avoids service interruption.

[0065] refer to Figure 4 , Figure 4 This is a schematic diagram of the structure of a network switching device according to a second embodiment of the present invention. Specifically, the network switching device 40 includes a network access module 41, a location determination module 42, and a network switching module 43.

[0066] The network switching device 40 supports at least two network standards, including a first network standard and a second network standard, wherein one of the first network standard and the second network standard is SA mode and the other is NSA mode.

[0067] The network access module 41 is configured to access a first network standard network. Specifically, the network access module 41 connects the user equipment to the first network standard network, which can be in SA mode or NSA mode. SA mode is a type of 5G network where the user equipment (5G terminal) connects to the 5G base station and 5G core network, better leveraging the advantages of 5G, such as ultra-low latency. NSA mode is another 5G network mode deployed based on the current 4G base station and network architecture.

[0068] The location determination module 42 is configured to determine the cell where the current location is located or the tracking area to which the cell belongs. After the network access module 41 connects the user equipment to the first network standard network, the location determination module 42 determines the cell where the user equipment is currently located or the tracking area to which the cell belongs.

[0069] The network switching module 43 is configured to switch from a first network standard to a second network standard based on the cell or tracking area.

[0070] Specifically, if the first network standard is SA mode and the second network standard is NSA mode, when the location determination module 42 detects that the user equipment cell or tracking area does not support VoNR, the network switching module 43 switches the first network standard network to the second network standard network. For example, the network switching module 43 switches the SA mode network to the NSA mode network.

[0071] If the first network standard is NSA mode and the second network standard is SA mode, when the location determination module 42 detects that the user equipment cell or tracking area supports VoNR, the network switching module 43 switches the first network standard network to the second network standard network. For example, the network switching module 43 switches the NSA mode network to the SA mode network.

[0072] The network handover device in this embodiment enables switching between a first network mode and a second network mode based on the user equipment's cell or tracking area. Specifically, when the user equipment's cell or tracking area does not support VoNR, the SA mode network is switched to the NSA mode network. When the user equipment's cell or tracking area supports VoNR, the NSA mode network is switched to the SA mode network. This achieves free switching between the two network modes, reduces handover difficulty and latency, and avoids service interruption.

[0073] refer to Figure 5 , Figure 5 This is a schematic diagram of a user equipment according to an embodiment of the present invention.

In one embodiment, the instructions, when executed, cause the processor 51 to: access a first network standard network; determine a subscription type to be executed; and switch from the first network standard network to a second network standard network based on the subscription type to be executed.

[0077] In one embodiment, when the instruction is executed, it causes the processor 51 to perform all the operations of the network switching method described in the second embodiment above.

[0078] Processor 51 can also be referred to as CPU (Central Processing Unit). Processor 51 can be an integrated circuit chip with signal processing capabilities. Processor 51 can also be a general-purpose processor, digital signal processor (DSP), application-specific integrated circuit (ASIC), field-programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic device, discrete hardware component.

The memory 52 reads and retrieves information according to the location specified by the controller. With memory, the electronic device has a memory function to ensure normal operation. The memory of an electronic device can be divided into main memory (RAM) and auxiliary memory (external memory) according to its purpose, or into external memory and internal memory. External memory is usually magnetic media or CD-ROM, which can store information for a long time. RAM refers to the storage component on the motherboard, used to store currently executing data and programs, but only for temporary storage of programs and data; power outages or power failures may result in data loss.

The non-transitory computer-readable storage medium 60 of the present invention is applied to a user equipment that supports at least two network standards, including a first network standard and a second network standard, wherein one of the first network standard and the second network standard is SA mode and the other is NSA mode.

[0081] The non-transitory computer-readable storage medium 60 stores instructions 61.
