Detailed Description
As cellular networks evolve from 4G LTE and NSA to 5G SA, UEs supporting dual SIM cards also evolve their DDS and nldds capabilities. Both DDS and nldds can support the NSA to 5G SA mode from before. Upgrading to 5G SA may provide better performance (higher throughput and low latency) for data services. However, for a dual SIM UE, considering that the nDDS daughter card is mainly used for voice call, some problems may occur if the nDDS daughter card is in 5G SA mode. In 5G SA mode, the voice options include EPS Fallback (initial stage solution) and VoNR (voice over NR, to be supported in later stages). The network upgrade to support VoNR also takes some time. Thus, EPS Fallback will be the primary choice for speech in 5G SA in the early stages of 5G SA deployment. EPS Fallback will introduce additional delay compared to NSA mode voice solutions (VoLTE, also known as LTE voice) because the UE will perform RAT changes from 5G to 4G LTE to complete the voice call setup. Furthermore, after the voice call is ended, the UE may need time to switch back to 5G again. IRAT (inter radio access technology) procedures may introduce significant delays (for voice call setup)/interrupt service (when returning from 4G to 5G). Furthermore, voice services involving IRAT procedures may have stability and power consumption issues. The initial coverage of 5G SA deployment is not wide. This means that the UE may often switch back and forth between 4G and 5G. Considering that the UE needs to complete the voice call to the 4G anyway, the present invention provides a dynamic network switching method to achieve free switching of two network modes, which will be specifically described by the following embodiments.
Referring to fig. 1, fig. 1 is a flowchart of a network handover method according to a first embodiment of the present invention, including the following steps.
Step S11: a first network system network is accessed.
Specifically, the user equipment is connected to a first network system network, and the first network system may be an SA mode or an NSA mode. Wherein the SA mode is one type of 5G network; in SA mode, the user equipment (5G terminal) is connected to the 5G base station and the 5G core network, so that the advantageous characteristics of 5G, such as ultra-low latency, can be better exerted. NSA mode is another 5G network mode deployed on the basis of the current 4G base station and network architecture.
Step S12: the type of subscription to be performed is determined.
And determining the subscription type to be executed by the user equipment, wherein the subscription type to be executed at least comprises a voice type and a data type. Specifically, whether the subscription type to be executed is a voice type or not can be determined according to the EPS Fallback times; and determining whether the subscription type to be executed is a data type according to the number of SCG bearing mechanisms.
In one embodiment, the EPS Fallback number is detected within a preset detection period; if the EPS Fallback times are greater than a first preset threshold, determining that the subscription type to be executed is a voice type; it can be understood that if the EPS Fallback number is smaller than the first preset threshold, determining that the subscription type to be executed is a non-voice type; whether the subscription type is a data type or not can be determined by presetting the number of SCG bearing mechanisms in the detection period. Specifically, the number of SCG bearers within a preset detection period is detected, and 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.
In one embodiment, in determining the type of subscription to be performed, it may be determined whether the network maintaining access to the first network format has ended. Determining a subscription type to be executed when determining that the network maintaining access to the first network system has ended; or after determining that the network maintaining access to the first network format has ended, determining a subscription type to be performed.
Step S13: and switching from the first network system network to the second network system network according to the subscription type to be executed.
And switching the network connected with the user equipment from the first network system network to the second network system network according to the subscription type to be executed. The second network system may be an NSA mode or an SA mode.
It may be appreciated that the first network system may be an SA mode and the second network system may be an NSA mode; alternatively, the first network system may be an NSA mode and the second network system may be an SA mode.
In a specific embodiment, assuming that the first network system is SA mode and the second network system is NSA mode, the subscription type to be performed is determined. If the subscription type to be executed is the data type, maintaining the user equipment in a first network system, namely an SA mode network; if the subscription type to be performed is a voice type, the first network-based network is switched to the second network-based network, 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 type of subscription to be performed may be determined. In this case, if the subscription type to be performed is determined as the data type, the second network-type network is switched to the first network-type network again, i.e., the NSA mode network is switched to the SA mode network again.
In this embodiment, after switching the SA-mode network to the NSA-mode network, it is detected whether the user equipment enters a tracking area or cell supporting VoNR. In particular, if the user equipment enters a tracking area or cell supporting VoNR, the NSA mode network is switched to the SA mode network.
It will be appreciated that the user equipment establishes a database in which all of the VoNR-supported or VoNR-unsupported tracking areas or cells are stored. The user equipment is used for detecting the current cell or tracking area by using the positioning equipment, the current cell or tracking area is compared with data stored in a database, and whether the current cell or tracking area supports VoNR is determined.
In another embodiment, after switching the SA-mode network to the NSA-mode network, it is detected whether the user equipment camps on an LTE cell that does not support NSA. If the user equipment resides in an LTE cell that does not support NSA, switching the NSA mode network to the SA mode network.
It will be appreciated that the user equipment establishes a database in which all NSA-capable LTE cells or all non-NSA-capable LTE cells are stored. And detecting a cell at the current position by using the user equipment by using the positioning equipment, comparing the cell at the current position with data stored in a database, and determining whether the cell at the current position is an LTE cell supporting NSA.
In another embodiment, assuming that the first network system is NSA mode and the second network system is SA mode, the subscription type to be performed is determined. If the subscription type to be executed is a voice type, maintaining the user equipment in a second network system, namely an SA mode network; if the subscription type to be performed is a data type, the first network-type network is switched to the second network-type 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 type of subscription to be performed may be determined; and if the subscription type to be executed is the voice type, switching the second network type network to the first network type network again, namely switching the SA mode network to the NSA mode network again.
In this embodiment, after switching the NSA mode network to the SA mode network, it is detected whether the user equipment enters a tracking area or cell that does not support VoNR. In particular, 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.
In a specific embodiment, the number of handovers is recorded each time a handover occurs between the first network-based network and the second network-based network. For example, when user equipment access is switched from a first network system network to a second network system network, the number of switching times is recorded as 1; when the user equipment access is switched from the second network system network to the first network system network, the switching times are recorded as 2, and the like.
In one embodiment of the invention, the number of handovers is introduced as a basis for determination when determining the type of subscription to be performed. Specifically, when the EPS Fallback number is greater than a first preset threshold and the handover number is less than a preset number, it is determined that the subscription type to be executed is a voice type. And in a preset monitoring period, when the number of the SCG bearing mechanisms is larger than a second preset threshold value and the switching times are smaller than the preset times, determining the subscription type to be executed as the data type.
According to the network switching method, the network in SA mode and the network in NSA mode are switched according to the subscription type to be executed, and free switching between the two network modes can be realized. In the technical scheme of the invention, the number of EPS Fallback determines whether the subscription type to be executed is a voice type, and the number of SCG bearing mechanisms determines whether the subscription type to be executed is a data type, so that the free switching of two network modes based on the subscription type is realized, the switching difficulty is reduced, the switching delay is reduced, and the service interruption is avoided.
Referring to fig. 2, fig. 2 is a flowchart of a network handover method according to a second embodiment of the present invention, including the following steps.
Step S21: a first network system network is accessed.
In particular, the user equipment is connected to a first network system, which may be an SA mode or an NSA mode. Wherein the SA mode is one type of 5G network; in SA mode, the user equipment (5G terminal) is connected to the 5G base station and the 5G core network, so that the advantageous characteristics of 5G, such as ultra-low latency, can be better exerted. NSA mode is another 5G network mode deployed on the basis of the current 4G base station and network architecture.
Step S22: and determining a cell at the current position or a tracking area to which the cell belongs.
Specifically, after the user equipment is connected to the first network system network, a cell of the current position of the user equipment or a tracking area to which the cell belongs is determined.
Step S23: and switching from the first network system network to the second network system network according to the cell or the tracking area.
Specifically, if the first network system is the SA mode and the second network system is the NSA mode, when it is detected that the cell or tracking area of the user equipment does not support the VoNR, the first network system network is switched to the second network system network, for example, the SA mode network is switched to the NSA mode network.
If the first network system is the NSA mode and the second network system is the SA mode, when the cell or tracking area of the user equipment supports the VoNR, the network of the first network system is switched to the network of the second network system, for example, the network of the NSA mode is switched to the network of the SA mode.
The network switching method of the embodiment realizes switching between the first network mode network and the second network mode network according to the cell or the tracking area of the user equipment. In particular, when the cell or tracking area of the user equipment does not support VoNR, the SA-mode network is switched to the NSA-mode network. When the cell or tracking area of the user equipment supports VoNR, the NSA mode network is switched to the SA mode network. Therefore, the free switching of the two network modes is realized, the switching difficulty is reduced, the switching delay is reduced, and the service interruption is avoided.
Referring to fig. 3, fig. 3 is a schematic diagram of a network switching apparatus according to a first embodiment of the present invention. Specifically, the network switching apparatus 30 includes a network access module 31, a subscription determination module 32, and a network switching module 33.
The network switching module 30 supports at least two network systems including a first network system and a second network system; one of the first network system and the second network system is in SA mode, and the other is in NSA mode.
The network access module 31 is configured to access the first network-based network. Specifically, the network access module 31 is configured to connect the user equipment to a first network-based network, which may be SA mode or NSA mode; among them, the SA mode is a type of 5G network, and the user equipment (5G terminal) is connected to the 5G base station and the 5G core network in the SA mode, so that the advantageous characteristics of 5G, such as ultra-low latency, can be better exerted. NSA mode is another 5G network mode deployed on the basis of the current 4G base station and network architecture.
The subscription determination module 32 is configured to determine the type of subscription to be performed. Specifically, the subscription determining module 32 may determine whether the subscription type to be executed is a voice type according to the EPS Fallback number; and determining whether the subscription to be executed is a data type according to the number of the SCG bearing mechanisms. In one embodiment, the subscription determination module 32 detects the EPS Fallback number within a preset detection period; if the EPS Fallback number is larger than a first preset threshold, determining that the subscription type to be executed is a voice type; it can be appreciated that if the EPS Fallback number is less than the first preset threshold, it is determined that the subscription type to be performed is not a voice type. The subscription determination module 32 may determine whether the subscription type is a data type by presetting the number of SCG bearers within the detection period. Specifically, the subscription determination module 32 detects the number of SCG bearers within the preset detection period, and determines that the type of subscription to be performed is a data type if the number of SCG bearers is greater than the second preset threshold.
In one embodiment, subscription determination module 32, in determining the type of subscription to be performed, needs to determine whether the network maintaining access of the first network format has ended. When it is determined that maintaining the first network-based network has ended, the subscription determination module 32 determines a type of subscription to be performed; alternatively, the subscription determination module 32 determines the type of subscription to be performed after determining that maintaining the first network-based network has ended.
The network switching module 33 is configured to switch from the first network-based network to the second network-based network according to the type of subscription to be performed.
Specifically, assume that the first network system is SA mode and the second network system is NSA mode. If the subscription determination module 32 determines that the type of subscription to be performed is a data type, the user equipment is kept access to the first network system, i.e. the SA mode network. If the subscription determination module 32 determines that the subscription type to be performed is a voice type, the network switching module 33 switches the first network-type network to the second network-type 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 determining module 32 may determine a subscription type to be performed, and if the subscription type to be performed determined by the subscription determining module 32 is a data type, the network switching module 33 switches the second network-mode network to the first network-mode network again, that is, the network switching module 33 switches the second network-mode network to the first network-mode network. In other words, the network switching module 33 switches the NSA mode network to the SA mode network again.
In the present embodiment, after switching the SA-mode network to the NSA-mode network, the network switching module 33 detects whether the user equipment enters a tracking area or cell supporting VoNR by using the subscription determining module 32. Specifically, if the user equipment enters a tracking area or cell supporting VoNR, the network switching module 33 switches the NSA mode network to the SA mode network.
In the present embodiment, after the network switching module 33 switches the SA-mode network to the NSA-mode network, the subscription determining module 32 is used to detect whether the user equipment resides in an LTE cell that does not support NSA, and if the user equipment resides in an LTE cell that does not support NSA, the network switching module 33 switches the NSA-mode network to the SA-mode network.
Specifically, assume that the first network system is in NSA mode and the second network system is in SA mode. The subscription determination module 32 determines a subscription type to be performed, and if the subscription type to be performed determined by the subscription determination module 32 is a voice type, maintains the user equipment in a second network system, i.e., an SA-mode network. If the subscription type to be performed, which is determined by the subscription determination module 32, is a data type, the network switching module 33 switches the first network-type network to the second network-type network, i.e., 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 determining module 32 may determine the type of subscription to be performed; if the subscription type to be performed is a voice type, the network switching module 33 switches the network of the second network mode to the network of the first network mode again, i.e., the network switching module 33 switches the network of the SA mode to the network of the NSA mode again.
In the present embodiment, after the network switching module 33 switches the network of NSA mode to the network of SA mode, the subscription determining module 32 detects whether the user equipment enters 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 SA-mode network to the NSA-mode network.
In a specific embodiment, the network switching module 33 may also record the number of times of switching each time a switch occurs between the first network-based network and the second network-based network. For example, when the network to which the user equipment is connected is switched from the first network system network to the second network system network, the network switching module 33 records the number of switching times as 1, when the network to which the user equipment is connected is switched from the second network system network to the first network system network, the network switching module 33 records the number of switching times as 2, and so on.
In one embodiment of the present invention, when the subscription determination module 32 determines the type of subscription to be performed, the number of handovers is introduced as a basis for the determination. Specifically, when the subscription determining module 32 determines that the EPS Fallback number of times is greater than the first preset threshold value and the number of times of switching recorded by the network switching module 33 is less than the preset number of times, it is determined that the subscription type to be performed is the voice type. In the preset monitoring period, when the subscription determining module 32 determines that the number of SCG bearers is greater than the second preset threshold and the number of switching times recorded by the network switching module 33 is less than the preset number, it is determined that the subscription type to be executed is the data type.
The network switching device of the embodiment switches between the network of the SA mode and the network of the NSA mode according to the subscription type to be executed, and can realize free switching of the two network modes. In the technical scheme of the invention, the number of EPS Fallback determines whether the subscription type to be executed is a voice type, and the number of SCG bearing mechanisms determines whether the subscription type to be executed is a data type, so that the free switching of two network modes based on the subscription type is realized, the switching difficulty is reduced, the switching delay is reduced, and the service interruption is avoided.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a network switching apparatus 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.
The network switching device 40 supports at least two network systems including a first network system and a second network system, one of the first network system and the second network system being in an SA mode and the other being in an NSA mode.
The network access module 41 is configured to access a first network-based network. Specifically, the network access module 41 connects the user equipment to a first network-based network, which may be either SA mode or NSA mode. Among them, the SA mode is a type of 5G network, and the user equipment (5G terminal) is connected to the 5G base station and the 5G core network in the SA mode, so that the advantageous characteristics of 5G, such as ultra-low latency, can be better exerted. NSA mode is another 5G network mode deployed on the basis of the current 4G base station and network architecture.
The location determination module 42 is configured to determine a cell or tracking area to which the cell belongs for the current location. After the network access module 41 connects the user equipment to the first network system network, the location determining module 42 determines a cell in which the user equipment is currently located or a tracking area to which the cell belongs.
The network switching module 43 is configured to switch from a first network-based network to a second network-based network according to a cell or tracking area.
Specifically, if the first network system is the SA mode and the second network system is the NSA mode, when the location determining module 42 detects that the cell or tracking area of the user equipment does not support VoNR, the network switching module 43 switches the first network system network to the second network system network, for example, the network switching module 43 switches the SA mode network to the NSA mode network.
If the first network system is the NSA mode and the second network system is the SA mode, when the location determining module 42 detects that the cell or tracking area of the user equipment supports the VoNR, the network switching module 43 switches the first network system network to the second network system network, for example, the network switching module 43 switches the NSA mode network to the SA mode network.
The network switching device of the embodiment realizes the switching between the network of the first network mode and the network of the second network mode according to the cell or the tracking area of the user equipment. In particular, when the cell or tracking area of the user equipment does not support VoNR, the SA-mode network is switched to the NSA-mode network. When the cell or tracking area of the user equipment supports VoNR, the NSA mode network is switched to the SA mode network. Therefore, the free switching of the two network modes is realized, the switching difficulty is reduced, the switching delay is reduced, and the service interruption is avoided.
Referring to fig. 5, fig. 5 is a schematic structural diagram of a user equipment according to an embodiment of the present invention. The user equipment 50 of the present invention supports at least two network systems including a first network system and a second network system, wherein one of the first network system and the second network system is in SA mode and the other is in NSA mode.
