Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a network switching method and apparatus, an electronic device, and a storage medium.
Background
Mobile communication networks are in the process of gradual development, and at the initial stage of network construction, the stability of the network is usually poor, thereby affecting the user experience. For example, it is still in the initial laying stage of 5G SA (standard one) network, and although SA network also has better performance such as high bandwidth, high rate, etc., the network stability is poor.
To obtain a stable network, the user may turn off the switch of the SA network. The terminal informs the network that the terminal does not support the SA network, and then switches to the non-SA network.
However, in the above handover procedure, the terminal needs to frequently adjust the SA network configuration, and needs to search for the target network during handover, and then initiate random access to the searched target network, etc., which results in a complex procedure and a long network search time, so that the terminal may have a long network interruption, and the user experience is poor.

Fig. 1 is a flowchart illustrating a network handover method according to an exemplary embodiment of the disclosure. The network switching method shown in this embodiment may be applied to a terminal, where the terminal includes but is not limited to a mobile phone, a tablet computer, a wearable device, a sensor, an internet of things device, and other electronic devices. The terminal may communicate with a base station as a user equipment, and the base station includes but is not limited to a 4G base station, a 5G base station, and a 6G base station.
As shown in fig. 1, the method may include the steps of:
step S101, responding to that a first network where the terminal is currently resident does not meet a preset condition, and initiating a voice call based on a fallback mechanism to the first network.
In one embodiment, the terminal may preset a judgment condition for the network and then determine whether the currently camped first network satisfies the condition.
In one embodiment, the terminal may determine whether the network status of the first network satisfies a preset condition. For example, the preset condition may be determined according to one or more of a network packet loss rate, a network signal-to-noise ratio, a strength of a network signal, or other relevant indicators, for example, the preset condition may be whether the network packet loss rate is smaller than a preset threshold.
In one embodiment, if the network status of the first network meets the preset condition determined according to the index, determining that the first network meets the preset condition; and if the network state of the first network does not meet the preset condition determined according to the index, determining that the first network does not meet the preset condition.
In one embodiment, the terminal may determine whether the network status of the first network matches the application scenario of the current terminal. For example, corresponding network states may be preset for different application scenarios of the terminal, for example, a game application scenario, a video call application scenario, and the like may correspond to a high-stability network.
In one embodiment, if the network state of the first network is matched with the application scene, determining that the first network meets a preset condition; and if the network state of the first network is not matched with the application scene, determining that the first network does not meet the preset condition. For example, for an SA network, it may be determined that the SA network is a low stability network, and when the application scenario corresponds to a high stability network, it is determined that the first network does not satisfy the preset condition; and when the application scene corresponds to the low-stability network, determining that the first network does not meet the preset condition.
In one embodiment, whether the first network satisfies the preset condition may be synthetically determined in combination with whether the network state of the first network satisfies the preset condition and whether the network state of the first network matches the application scenario of the current terminal. For example, when the network state of the first network meets a preset condition and the network state of the first network matches the current application scenario, determining that the first network meets the preset condition; and when the network state of the first network does not meet the preset condition or the network state of the first network is not matched with the current application scene, determining that the first network does not meet the preset condition.
It should be noted that the method for determining whether the first network meets the preset condition is only an exemplary description, and in practical applications, the determination may be performed by other methods, which is not limited in this embodiment.
In one embodiment, if the terminal determines that the first network currently residing in does not meet the preset condition, the terminal actively initiates a voice call based on a fallback mechanism to the first network.
In one embodiment, the first network may be a 5G network, and the terminal may initiate an EPSFB-based voice call to the first network. Alternatively, the first network may be another network, and the terminal may initiate a voice call corresponding to the network.
Step S102, receiving indication information returned by the first network, wherein the indication information carries information of a second network meeting preset conditions.
Step S103, accessing the second network based on the indication information.
In an embodiment, after receiving a voice call based on a fallback mechanism sent by a terminal, a first network may return indication information to the terminal, where the indication information carries information of a second network that meets a preset condition.
In one embodiment, the indication information may include frequency point information of the second network.
In an embodiment, the first network may determine an optimal second network from one or more second networks meeting a preset condition according to the location of the terminal, and then carry information of the second network in the indication information, for example, the information may be information of a cell frequency point which belongs to the second network and is closest to the terminal. In one embodiment, the first network may interact with the second network, for example, sending information about the terminal to the second network, and so on.
In one embodiment, the first network may send a handover indication to the terminal, and information of the second network is carried in the handover indication. The terminal may receive the handover indication, disconnect from the first network, and initiate an access request to the second network.
In one embodiment, the first network may release the connection with the terminal, for example, may be an RRC release message, and may carry redirection information in the message for releasing the connection. The terminal may receive the redirection information and then initiate an access request to the second network.
Still taking the first network as the 5G network as an example, the terminal may initiate a voice call based on the EPSFB to the 5G network. After receiving the voice call, the 5G network may send indication information to the terminal in view of that the voice call is based on the EPSFB, and carry information of the second network in the indication information, for example, the second network may be a 4G network. Therefore, the terminal can disconnect from the 5G network and access into the 4G network according to the indication information.
It should be noted that the first network and the second network may include a core network, a base station, and the like. In the above embodiments, the interaction between the terminal and the core network and the interaction between the terminal and the base station are included, and for convenience of description, the core network and the base station are not distinguished, but are collectively described as the interaction between the terminal and the network.
In the related art, a voice call based on a fallback mechanism is generally applied to some mobile communication networks that cannot directly perform a voice call, and for a network that cannot perform a voice call, a terminal may perform a call service by using a fallback mechanism to fall back to a network that can perform a voice call. For example, a terminal in a 5G SA networking may fall back from a 5G network to a 4G network by using an EPSFB technique, and then perform a Voice call in the 4G network by using a Voice over Long-Term Evolution (lte) technique; or a terminal in the 4G network that does not support VoLTE may use the CSFB technique to perform a voice call from the 4G network back to the 3G/2G network.
In the embodiment of the disclosure, the fallback mechanism is applied to the conventional network handover, and the terminal actively initiates a voice call based on the fallback mechanism under the condition that the currently-resident first network does not meet the preset condition, so that the first network issues the indication information carrying the second network information, and the terminal can access the second network according to the indication information. It should be noted that the voice call initiated by the terminal is not a real voice call, that is, the user does not need to make a voice call, but is initiated for network handover.
According to the embodiment of the disclosure, the fallback mechanism is applied to the conventional network switching, the terminal can be accessed to the second network according to the indication of the first network, and compared with the prior art in which the terminal searches the second network after disconnecting the first network, the process is simplified, the network disconnection for a long time caused by network searching is avoided, and the network switching can be realized more smoothly.
In addition, the terminal can flexibly switch according to whether the current resident network meets the requirement or not, dynamically adapt to the network state, the application scene of the terminal and the like, and improve the adaptability of the terminal to the network.
Fig. 2 is a flowchart illustrating another network handover method according to an exemplary embodiment of the disclosure. As shown in fig. 2, the method may further include:
in step S201, in response to the terminal successfully accessing the second network, the voice call is ended in the second network.
In one embodiment, the terminal terminates the previously initiated voice call based on the fallback mechanism in the second network after successfully accessing the second network.
It should be noted that, according to the fallback mechanism, after the terminal initiates the voice call in the first network, the first network may instruct the terminal to fall back to the second network for performing the voice call, for example, the terminal may first access the second network and then initiate a call request to the second network.
In the embodiment of the present disclosure, the terminal does not access the second network for the voice call, but actively initiates the voice call to the first network for accessing the second network. Therefore, the terminal can immediately end the voice call after successfully accessing the second network, for example, the terminal can directly end the voice call without initiating a call request to the second network, which not only saves communication resources, but also avoids misunderstanding or loss to users.
Fig. 3 is a flowchart illustrating another network handover method according to an exemplary embodiment of the disclosure. As shown in fig. 3, the method may further include:
in step S301, a capability update message is sent to the second network to indicate that the second network does not support the first network.
In the related art, according to the fallback mechanism, after detecting that the voice call of the terminal is ended, the second network may instruct the terminal to return to the first network, that is, instruct the terminal to re-access the first network. For example, the second network may carry redirection or handover information in the RRC release message, for example, the redirection or handover information may include frequency point information of the first network, so that the terminal may return to the first network according to the RRC release message. In addition, the terminal may also actively return to the first network, for example, actively search for and return to the first network based on the fastretrn mechanism, and the like.
In one embodiment, the terminal initiates a voice call to the first network only when accessing the second network, and in order to avoid the terminal returning to the first network according to the method in the related art, the terminal may send a capability Update message, such as TAU (Tracking Area Update), to the second network, and indicate to the second network through the capability Update message: the terminal does not support the first network.
In one embodiment, when the second network determines that the capability of the terminal includes the first network, the second network no longer instructs the terminal to return to the first network by means of redirection or handover.
In one embodiment, the terminal no longer returns to the first network through the FastReturn mechanism.
According to the embodiment of the disclosure, the terminal may prevent the second network from instructing the terminal to return to the first network by updating the capability information to the second network. Therefore, the terminal can stably reside in the second network and perform related communication operations.
In one embodiment, the terminal may also revert back to the first network, as described below in conjunction with fig. 4.
Fig. 4 is a flowchart illustrating another network handover method according to an exemplary embodiment of the disclosure. As shown in fig. 4, the method may further include:
in step S401, in response to the first network satisfying a preset condition, returning to the first network from the second network.
In one embodiment, the terminal may determine whether the network status of the first network satisfies a preset condition. For example, the terminal may periodically detect the first network after accessing the second network, e.g., may periodically measure a cell in the first network where the terminal previously camped. If the network state of the first network meets the preset condition, the terminal can return to the first network.
In one embodiment, the terminal may determine whether the network status of the first network matches the application scenario of the current terminal. For example, when the terminal enters an application scenario required by the high-stability network, the terminal may fall back from the first network to the second network according to the method of the foregoing embodiment, and when the terminal ends the application scenario required by the high-stability network, the terminal may return to the first network from the second network. For example, when the terminal performs a video call, the terminal falls back to the second network, and returns to the first network after the video call is ended.
In one embodiment, the terminal may return to the first network when it is determined that the network status of the first network satisfies the preset condition and matches the application scenario of the current terminal.
It should be noted that, the above method for determining whether the first network satisfies the preset condition is only an exemplary description, and is not limited in particular. In practical application, the determination may be performed according to other methods, which are not described herein again.
In one embodiment, the terminal returns to the first network in case that the terminal determines that the first network meets the preset condition.
In one embodiment, the terminal may store information of a cell camped in the first network, such as location information of the cell, cell identification, frequency point information, and the like, before falling back to the second network. Therefore, when the terminal determines that the terminal needs to return to the first network, the terminal accesses the first network again through the stored information of the cell.
In one embodiment, the terminal may perform cell search in the first network to re-access the first network through the searched cell when it is determined that the terminal needs to return to the first network.
It should be noted that the method for returning to the first network is only an exemplary description, and this embodiment is not specifically limited.
In step S402, a capability update message is sent to the first network to indicate that the terminal supports the first network.
In one embodiment, the terminal indicates to the second network that the terminal capability does not support the first network after accessing the second network. The first network may obtain the capability information of the terminal from the second network, and in order to avoid the first network rejecting the terminal access, the terminal may send a capability update message to the first network, and instruct the first network through the capability update message: the terminal supports a first network.
In one embodiment, the first network may accept access by the terminal upon determining that the terminal supports the first network. Therefore, the terminal can stably reside in the first network and perform related communication operations through the first network.
According to the embodiment of the disclosure, the terminal can dynamically adapt according to network changes and/or the change of the requirement of the terminal, and flexibly switch the network.
One specific embodiment of the present disclosure is described below in conjunction with fig. 5.
Fig. 5 is a flowchart illustrating another network handover method according to an exemplary embodiment of the disclosure. As shown in fig. 5, the method may include:
in step S501, the terminal determines whether the first network satisfies a preset condition, and if not, the terminal executes step S502; and if the preset condition is met, the terminal still resides in the first network and does not perform network switching.
In step S502, the terminal initiates a voice call based on a fallback mechanism to the first network. For example, the first network may be a 5G SA network and the second network may be a 4G network, and the terminal initiates a voice call based on EPSFB to the first network.
In step S503, after receiving the voice call of the terminal, the first network may instruct the terminal to fall back to the second network for a voice call because the voice call is based on the fall-back mechanism. And the first network returns a switching instruction to the terminal to indicate the terminal to switch to the second network.
In step S504, the terminal disconnects from the first network according to the instruction of the first network, and accesses the second network.
In step S505, the terminal requests the second network to end the voice call.
In step S506, the terminal updates the capability information to the second network to inform that the second network does not support the first network.
Since the second network determines that the terminal does not support the first network, the second network does not instruct the terminal to return to the first network, and thus the terminal can stably reside in the second network.
In step S507, after accessing the second network, the terminal may still evaluate the first network, and determine whether the first network meets the preset condition. If the first network is determined to satisfy the preset condition, step S508 is executed, and if the first network is determined not to satisfy the preset condition, the terminal device still resides in the first network.
In step S508, the terminal may disconnect from the second network and return to the first network again.
