Description
Technical Field
The invention relates to the technical field of communication, in particular to a network residing method and device of a 5G terminal supporting VoWIFI, a storage medium and a terminal.
Background
Conventionally, a fifth Generation mobile communication technology (5th-Generation, abbreviated as 5G) network is specified in a third Generation Partnership Project (3rd Generation Partnership Project, abbreviated as 3GPP) Protocol to indicate support of Internet Protocol (IP) Multimedia Subsystem technology (Multimedia Subsystem), that is, an IMS service includes the following 2 scenarios: scenario 1, a 5G network supports direct provision of IMS services over a 5G radio access network (NG RAN) connection; scene 2, 5G network does not support direct provision of IMS services based on NG RAN connection, but supports provision of IMS services by redirection or handover to an Evolved Packet System (EPS for short). Wherein, the 5G earlier stage in the scenario 2 is a mode for providing IMS services.
The protocol also specifies a terminal that accesses a 5G network in a 3GPP manner, and if the 5G network indicates that IMS service is not supported and the terminal is voice-preferred, the terminal cannot use the 5G network and should switch to a 4 th generation mobile communication network (4 generation mobile communication network) by turning off a new air interface service (disable NR)thGeneration, 4G for short) to enable telephone service.
Based on this, at the present stage of 5G, neither the network nor the terminal supports accessing a 5G Core network (5G Core network, abbreviated as 5GC) through a Non-3GPP (Non-3GPP) mode, but the network and the terminal generally support a Voice of Wi-Fi (Voice over wifi, abbreviated as VoWIFI) based on a wireless access technology (Wi-Fi). When the 5G network supports IMS services in the form of scenario 1 above, then the existing protocol supports IMS services switching between Wi-Fi and 5G.
However, if the IMS service supported by the 5G network is in the form of scene 2, the IMS service cannot be switched between Wi-Fi and 5G, that is, when the network supports the IMS service in the form of scene 2, the terminal resides in 5G, and for the terminal supporting VoWIFI, if the 5G network does not support the IMS service, the terminal cannot reside in 5G according to the protocol, which will affect the user experience of using the telephone service.

Detailed Description
In the prior art, when the 5G network does not support direct IMS service provision based on NG RAN connection, the 5G network can continue to reside, and the user is guaranteed to use the telephone service, thereby improving the user experience.
In order to solve the above problem, an embodiment of the present invention provides a network residing method for a 5G terminal supporting VoWIFI, where the method includes: when the terminal is in a 5G network and is in a standby state, detecting whether the current terminal is in voice priority; if the current voice is prioritized and the network does not support VoNR, detecting whether the VoWIFI service can be provided currently; when the VoWIFI service can be provided currently, the 5G network is kept resident and telephone service is carried out through VoWIFI.
By the method, when the terminal is in a standby state and the 5G network does not support direct IMS service provision based on NG RAN connection, the terminal can continuously reside in the 5G network and use the telephone service through VoWIFI, so that user experience is improved.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, fig. 1 is a schematic flowchart of a network residing method of a 5G terminal supporting VoWIFI according to an embodiment of the present invention. The method may be executed by a terminal side, and the terminal may be User Equipment (UE), such as various appropriate devices such as a mobile phone, a computer, and a mobile watch. The method specifically includes the following steps S101 to S103, which are described in detail below.
Step S101, when the terminal resides in a 5G network and is in a standby state, whether the current terminal is in a voice priority state is detected; if the current voice is prioritized and it is detected that the network does not support the VoNR, step S102 is executed to detect whether the VoWIFI service can be currently provided; when the VoWIFI service can be provided currently, step S103 is executed, the 5G network is kept resident, and telephone service is carried out through VoWIFI.
When the terminal detects that the terminal resides in a 5G network and is in a standby state, if the terminal is currently configured to have Voice priority, the terminal first detects whether a network accessed by the terminal supports a New air interface-based telephone service (Voice of New Radio, VoNR for short). If the network does not support the service, the 5G is switched to the 4G temporarily according to the protocol, and whether the terminal can currently provide the VoWIFI service or not is continuously detected, namely whether the terminal can perform the telephone service (namely the voice call service) through the VoWIFI or not is detected. At the moment, the terminal continues to reside in the 5G network accessed by the terminal, and telephone service is carried out through VoWIFI.
Optionally, the step S102 in fig. 1 of detecting whether the VoWIFI service can be currently provided includes: detecting whether VoWIFI is supported currently or not, and if so, detecting whether IMS registration based on WIFI can be carried out or not; and if the WIFI-based IMS registration can be carried out, the VoWIFI service can be provided currently.
The terminal detects whether the terminal can provide VoWIFI service at present, and IMS registration based on WIFI is required to be completed with a network side. Therefore, it is necessary to determine that the terminal itself supports the voip and then determine that the terminal can perform IMS registration based on WIFI.
Optionally, if VoWIFI is currently supported, the 5G network remains resident.
It should be understood that, in the prior art, a terminal which passes through the resident 5G network and has a voice priority will change the configuration to turn off the 5G NR function (i.e. disable NR) after detecting that the network does not support VoNR, thereby stopping the resident 5G network. In order to ensure that the terminal can continuously reside in the 5G network, when detecting that the terminal currently supports VoWIFI, disable NR operation is not performed, and the 5G NR function is kept on.
By the method, when the terminal is in a standby state and the 5G network does not support direct IMS service provision based on NG RAN connection, the terminal can continuously reside in the 5G network and use the telephone service through VoWIFI, so that user experience is improved.
In an embodiment, please refer to fig. 2, where fig. 2 is a schematic flowchart of a second network residing method of a 5G terminal supporting VoWIFI according to an embodiment of the present invention, and the method further includes: if the step S102 detects that the VoWIFI service cannot be provided currently, executing the step S201, leaving the 5G network and residing in the 4G, 3G or 2G network; providing telephony services over the 4G, 3G or 2G networks.
That is, if the terminal cannot provide the voip service, the terminal with the Voice priority needs to be switched to the 4G network, and perform a telephone service through a Voice over Long-Term Evolution (VoLTE) bearer. Please refer to the related description in fig. 1 for other steps in fig. 2, which are not described herein again.
Further, when the terminal does not support the VoWIFI or loses the WiFi coverage, it may be determined that the terminal cannot currently provide the VoWIFI service.
More specifically, if the terminal itself does not support the voip function, it may be determined that the terminal cannot provide the voip service. Or the terminal loses WiFi coverage, the telephone service cannot be continuously completed through WiFi, and the situation that VoWIFI service cannot be provided currently can be judged.
In one embodiment, referring again to fig. 1, after leaving the 5G network to camp at step S103, the method further comprises: continuously detecting whether the VoWIFI service can be provided currently; and when detecting that the VoWIFI service can be provided currently, restoring the 5G network residence and carrying out telephone service through VoWIFI.
After the terminal leaves the 5G network due to loss of WiFi coverage and the like and resides, it still continues to detect whether it can currently provide the VoWIFI service (if so, recover the WiFi coverage and the like) according to step S102, and if so, triggers the terminal to return to 5G, and provides data service under 5G, that is, performs a phone service through VoWIFI.
In this embodiment, if the terminal leaves the 5G network residence due to reasons such as loss of WiFi coverage, the terminal can automatically reply to the 5G residence after the network is recovered, so as to improve the communication speed, thereby improving the user experience.
In an embodiment, please refer to fig. 3, fig. 3 is a flowchart illustrating a third network residing method of a 5G terminal supporting VoWIFI according to an embodiment of the present invention, where the method illustrated in fig. 3 may be performed on the premise of the methods illustrated in fig. 1 and fig. 2, or may be performed independently of the methods illustrated in fig. 1 and fig. 2. The case where the method of fig. 3 is performed separately may include: the terminal may remain camped on the 5G network when it detects that it cannot reselect to the 3G or 4G network, or may be configured to remain camped on the 5G network when voice is preferred and it detects that the network does not support VoNR.
In combination with the situation of the scene 2, in the existing protocol, the telephone cannot be switched to the 5G side in the VoWIFI telephone process, and once a WIFI signal is poor or coverage is lost, a call drop occurs, which may affect user experience.
In order to solve the above problem, an embodiment of the present invention further provides a method illustrated in fig. 3, where the method includes:
step S301, when residing in a 5G network and in a VoWIFI telephone service process, if the network does not support VoNR or does not support the IMS service provided based on NG RAN connection, acquiring WIFI strength or related quality data of VoWIFI data transmission;
step S302, judging whether to stay in the 5G network or not according to the WIFI intensity or the VoWIFI data transmission related quality data.
If the terminal still maintains the resident 5G network when voice is prioritized and it is detected that the network does not support VoNR, and when it is detected that the network does not support VoNR or does not support IMS service based on NG RAN connection, the terminal may actively acquire the WIFI strength or the quality data (such as error rate) related to the transmission of the VoWIFI data at this time when it is detected that the network does not support VoNR or does not support the provision of IMS service based on NG RAN connection, thereby determining whether to maintain the resident 5G network.
At this time, the terminal can actively judge whether the 5G network resides according to the obtained WIFI strength or the relevant quality data of the VoWIFI data transmission, instead of executing according to the original protocol, and can automatically trigger the switching between the 5G network and the 4G network (i.e. the switching between the VoWIFI and the VoLTE), thereby avoiding call drop.
In one embodiment, the determining whether to stay in the 5G network according to the WIFI strength or the voip data transmission related quality data in step S302 includes: when the WIFI strength or the VoWIFI data transmission related quality data is lower than a first threshold, judging whether the measurement of the 4G network is started at present; and if the 4G network neighbor cell information exists but the measurement of the 4G network is not started, starting the measurement of the 4G network.
The first threshold value is a numerical value corresponding to the WIFI strength or the VoWIFI data transmission related quality data and is a preset value. The first threshold value is used for triggering the terminal to start 4G network measurement.
And when the terminal side has 4G network neighbor cell information but the measurement of the 4G network is not started, the measurement of the 4G network is started immediately. At this time, the terminal side does not yet reach the condition for starting the 4G network neighbor cell measurement required by the protocol, that is, the method can trigger the terminal to start the 4G network measurement in advance, so that the terminal can immediately switch to the 4G network when needing to switch to the 4G network.
Optionally, after the starting of the measurement of the 4G network, the method further includes: and when the WIFI strength or the VoWIFI data transmission related quality data are not lower than a first threshold and the current condition does not meet the preset 4G network measurement condition, stopping the 4G network measurement.
After the measurement of the 4G network is started, the terminal still acquires the WIFI intensity or the relevant quality data of the VoWIFI data transmission, for example, the WIFI intensity or the relevant quality data may be acquired in real time or at a preset frequency. And when the acquired data is detected to be not lower than the first threshold and the current condition does not meet the preset 4G network measurement condition (namely the adjacent cell measurement condition of the starting 4G network which does not meet the protocol requirement), stopping the measurement of the 4G network.
In one embodiment, the determining whether to stay in the 5G network according to the WIFI strength or the quality data related to the VoWIFI data transmission in step S302 in fig. 3 includes: and when the WIFI intensity or the VoWIFI data transmission related quality data is lower than a second threshold, switching from the 5G network to the 4G network.
The second threshold is a value corresponding to the intensity of WIFI or the relevant quality data of VoWIFI data transmission, and is a preset value, and the second threshold is used for triggering the terminal to leave the 5G network and stay in the 4G network. The value of the first threshold is greater than that of the second threshold, and the value of the second threshold is greater than the threshold for switching from the VoWIFI to the VoLTE, wherein the threshold for switching from the VoWIFI to the VoLTE can be determined according to the existing protocol.
Optionally, in step S302 in fig. 3, determining whether to keep residing in the 5G network according to the WIFI strength or the relevant quality data of the VoWIFI data transmission further includes: and when the WIFI intensity or the VoWIFI data transmission related quality data is lower than a second threshold, switching from the 5G network to the 4G network.
Namely, if the terminal can determine the 4G network to be switched, and when the intensity of WIFI or the quality data related to the VoWIFI data transmission is lower than the second threshold, the terminal is triggered to actively switch from the 5G network to the 4G network. The proactive may refer to a terminal initiating a handover procedure.
By the method, the terminal can continuously reside in 5G under the condition that the 5G network does not support VoNR, and measures and switches to the 4G network in advance according to the relevant indexes during the VoWIFI telephone period, so that the VoWIFI is switched to the VoLTE, and call drop is avoided.
In one embodiment, after the switching from the 5G network to the 4G network, the method further includes: and when the WIFI intensity or the VoWIFI data transmission related quality data is not lower than the second threshold, switching from the 4G network to the 5G network.
After the terminal is switched from the 5G network to the 4G network according to the method, the terminal still obtains the WIFI intensity or the related quality data of VoWIFI data transmission in real time, and when the WIFI intensity or the related quality data of VoWIFI data transmission are detected to be not lower than the second threshold, the terminal can be immediately triggered to leave the 4G network to stay in the 5G network.
Optionally, if it is detected that the WIFI strength or the relevant quality data of the VoWIFI data transmission is not lower than the second threshold and the terminal currently has other data services, such as a high-speed data service, the terminal is immediately triggered to leave the 4G network to reside in the 5G network.
In another embodiment, after the switching from the 5G network to the 4G network, the method further includes: and when the WIFI intensity or the VoWIFI data transmission related quality data is not lower than the second threshold, switching the 4G network to the 5G network after the VoWIFI telephone service is ended.
When the WIFI strength or the VoWIFI data transmission related quality data are not lower than the second threshold, the 5G network can be switched back temporarily, and after the VoWIFI telephone service is ended, the 4G network is switched to the 5G network, so that the VoWIFI telephone service is prevented from being influenced.
