Description
Technical Field
The present invention relates to the field of computer application technologies, and in particular, to a network call handover method, a network call handover system, a mobile terminal, and a computer-readable storage medium.
Background
From 3G, 4G to 5G, the speed of surfing the internet by the mobile phone is faster and faster. However, for telecommunication operators, the difficulty of network coverage increases due to the higher and higher frequency bands used, which is a difficult problem to face. Especially, the indoor deep coverage is higher in difficulty, and inconvenience is brought to the user in indoor data networking and voice communication. WiFi is regarded as the 'key' for opening the 'door lock', as long as there is WiFi indoors, even if the mobile signal coverage is not good, the internet surfing can be realized easily, and WiFi can also meet the requirement of voice call in indoor scenes.
In foreign countries, the vowifi (voice over WiFi) or WiFi Calling service has been popular for many years. With the coming of the 5G era, the VoWiFi service is expected to help solve the indoor communication problem.
Recently, a certain mobile company has launched a "WiFi call assistant" application, and according to the introduction of this application by the authorities, "there is WiFi available for calling". In fact, VoWiFi is not a new thing in China, and operators develop research on the original support of VoWiFi of mobile phones many years ago, and App version VoWiFi services have appeared. In a domestic communication industry held four years ago, a domestic telecom operator displays the VoWiFi service on site and realizes bidirectional seamless switching between VoLTE and VoWiFi. That is to say, in the call state, the user can automatically select the network with better switching-in signal by the mobile phone according to the signal strength of the mobile network and the WiFi network, and provide the user with the VoLTE call or the volga call service, and the call is not interrupted before and after the switching.
The technology of VoLTE/VoWiFi is mature, and VoNR (Voice over NR, New Radio, New air interface, an interface for communication between a mobile phone and a base station) is coming, but because of other factors, VoWiFi is not popularized and applied. It would be helpful to ' rescue ' the operator's voice services if they could be generalized at that time. In the 4.0 era of communication, practically, in the 3.0 era, all voice bearers are in a large trend on IP networks. VoWiFi is still coming up, which is also one of RCS (converged communication). The current 5G era comes, indoor coverage difficulty is higher, VoWiFi can play a greater role, and the problem of voice communication is solved.
For example, in the United states, VoWiFi services have been introduced by operators such as AT & T, Verizon, T-Mobile for many years and are quite popular. In india, in late years and early days, terminal manufacturers see the new trend of mainstream operators, and mainstream manufacturers in india mobile phone markets also act in disputes, including Huashi, OPPO, Nokia, Samsung and the like, and release software updating plans to enable own mobile phones to support the VoWiFi function so as to meet the requirements of operators and users. For example, in late 6 months, OPPO introduced the ColoroS system in the Indian market and also supports VoWiFi. Recently, the popularity of promoting VoWiFi has emerged.
From a global perspective, VoWiFi is rapidly developing. The market research institute Mordor Intelligence published a report that VoWiFi market size is expected to grow from $ 19.2 billion in 2019 to $ 81.7 billion in 2025 with a compound annual growth rate of 27.24%. Most operators will simultaneously launch both the VoWiFi and VoLTE services, and then if the network supports VoNR, the network will also support both the VoWiFi and the VoNR services, so as to effectively improve the indoor network coverage and promote the evolution towards all-IP communication.
Overall, VoWiFi is advantageous to the operator. On one hand, although voice service income is sliding, users are rigid and necessary for voice communication requirements, the loss of the users is increased due to poor voice communication experience, and the VoWiFi can help operators to solve the problem of poor indoor coverage of the cellular network, so that the voice communication experience of the users is improved. Meanwhile, at present, common family users in large cities all have bandwidths of hundreds of megabytes or more than gigabytes, and WiFi communication services are provided by WiFi in the homes and office places of the users and public WiFi networks with large quantity, so that the load of cellular networks of operators can be reduced, and the release of spectrum resources is facilitated.
At present, the handover conditions considered by the handover schemes of VoLTE/VoNR and VoWiFi are relatively simple, and whether handover is needed is generally determined only according to a Threshold (Threshold) and a Timer (Timer), but the Threshold is only a fixed value, which easily causes ping pong handover (ping pong is a means of data buffering, and the efficiency of data transmission can be improved by ping pong operation). In addition, the switching scheme is only suitable for switching scenes of Wi-Fi and LTE/NR edge movement, because the switching to WiFi is only carried out when a poor signal enters an area with good WiFi coverage from LT/NR. If the user call preference setting is the mobile network preference, under the general condition of an LTE/NR signal, but under the good condition of a WiFi signal, the switching to the WiFi call cannot be triggered, so that the load of the cellular network of an operator cannot be reduced. However, if the WiFi signal is good, the network transmission delay is large, because the bandwidth, the traffic volume, or the network congestion affects, the speed of signal transmission may be poor when the signal is good, and the quality of the VoWi-Fi call may also be affected.
Accordingly, the prior art is yet to be improved and developed.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
At present, the handover conditions considered by the handover schemes of VoLTE/VoNR and VoWiFi are relatively simple, and whether handover is needed is generally determined only according to a Threshold (Threshold) and a Timer (Timer), but the Threshold is only a fixed value, which easily causes ping pong handover (ping pong is a means of data buffering, and the efficiency of data transmission can be improved by ping pong operation). In addition, the switching scheme is only suitable for switching scenes of Wi-Fi and LTE/NR edge movement, because the switching to WiFi is only carried out when a poor signal enters an area with good WiFi coverage from LT/NR. If the user call preference setting is the mobile network preference, under the general condition of an LTE/NR signal, but under the good condition of a WiFi signal, the switching to the WiFi call cannot be triggered, so that the load of the cellular network of an operator cannot be reduced. However, if the WiFi signal is good, the network transmission delay is large, because the bandwidth, the traffic volume, or the network congestion affects, the speed of signal transmission may be poor when the signal is good, and the quality of the VoWi-Fi call may also be affected.
Therefore, in view of the above-mentioned defects in the prior art, the network call switching method according to the preferred embodiment of the present invention, as shown in fig. 1, includes the following steps:
and step S10, when the mobile terminal carries out voice call, detecting and judging the current preference setting of the user, wherein the preference setting comprises mobile network preference and WiFi network preference.
Please refer to fig. 2, which is a flowchart of step S10 in the network call handover method according to the present invention.
As shown in fig. 2, the step S10 includes:
s11, the mobile terminal receives the operation instruction and starts the voice call function;
and S12, the mobile terminal detects the current preference setting of the user for the voice call and judges whether the preference setting is mobile network preference or WiFi network preference.
Specifically, in order to better determine whether to perform a handover of a call network, before the step S10, the method further includes: the method comprises the steps that a first preset signal threshold value used for judging whether a VoLTE or VoNR call is switched to a Vowi-Fi call or not is preset on the mobile terminal, and the first preset signal threshold value indicates the signal intensity of a current VoWiFi network; and the mobile terminal presets a second preset signal threshold value for judging whether the VoWiFi communication is switched to the VoLTE or VoNR communication, wherein the second preset signal threshold value represents the signal intensity of the current VoLTE or VoNR network. By setting the two conditions, the switching of the call network can be performed only when the signal values of the VoLTE network or the VoNR network and the VoWiFi network reach certain strength, so that the switching condition of a certain network is reduced, the call quality is not influenced, and convenience is brought to the use of a user.
The mobile terminal receives an operation instruction, a voice call function (such as IMS voice call) is started, the mobile terminal detects the current preferred setting of the voice call of a user, namely, the preferred setting is judged to be the mobile network priority or the WiFi network priority; the mobile network preferentially represents that the default selection network call when the mobile terminal carries out voice call is VoLTE or VoNR call, and the WiFi network preferentially represents that the default selection network call when the mobile terminal carries out voice call is VoWiFi call.
In addition, the first preset signal threshold is smaller than the second preset signal threshold, the first preset signal threshold ranges from-115 dBm to-100 dBm, such as from-115 dBm to-110 dBm to-105 dBm to-100 dBm, and the second preset signal threshold ranges from-85 dBm to-70 dBm, such as from-85 dBm to-80 dBm to-75 dBm to-70 dBm.
Step S20, if the priority is set as the mobile network priority, checking whether the mobile network signal is lower than a first preset signal threshold, if so, switching the VoLTE or VoNR call to the VoWiFi call.
Please refer to fig. 3, which is a flowchart of step S20 in the network call handover method according to the present invention.
As shown in fig. 3, the step S20 includes:
s21, when the mobile terminal recognizes that the priority of the current voice call is set as the priority of the mobile network, acquiring the current mobile network signal of the mobile terminal;
s22, the mobile terminal judges whether the mobile network signal is lower than the preset first preset signal threshold value;
and S23, if the mobile network signal is lower than the first preset signal threshold, switching the VoLTE or VoNR call used by the current voice call of the mobile terminal to the VoWiFi call.
Specifically, when the mobile terminal recognizes that the priority of the current voice call is set as the mobile network priority, that is, the mobile network priority indicates that the default selected network call when the mobile terminal performs the voice call is a VoLTE or VoNR call, a current mobile network signal of the mobile terminal is obtained, the mobile terminal determines whether the mobile network signal is lower than the preset first preset signal threshold, and if the mobile network signal is lower than the preset first preset signal threshold, it indicates that the quality of the current VoLTE or VoNR call is not good, so that if the mobile network signal is lower than the first preset signal threshold (for example, the mobile network signal is lower than-115 dBm), the VoLTE or VoNR call used by the current voice call of the mobile terminal is switched to a volga call, so that it can be ensured that a user performs a call on a network with the best network quality, the method can improve the call quality, reduce the call delay, and reduce the call drop rate and the call completing rate.
If the mobile network signal is lower than the first preset signal threshold, the strength of the VoWiFi network signal is better at the moment, the VoLTE or VoNR call can be switched to the VoWiFi call, the call quality cannot be influenced, the call quality of the VoWiFi network is better, and better experience is provided for users. If the current mobile network signal is greater than the first preset signal threshold, it indicates that the current VoWiFi network strength is not enough, then the switching is not performed, and the current mobile network signal is obtained again and compared with the first preset signal threshold, and the switching of the call network is not performed until the mobile network signal is lower than the first preset signal threshold.
Step S30, if the priority is set as the WiFi network priority, checking whether a WiFi network signal is lower than a second preset signal threshold, if so, switching the VoWiFi call to VoLTE or VoNR call.
Please refer to fig. 4, which is a flowchart of step S30 in the network call handover method according to the present invention.
As shown in fig. 4, the step S30 includes:
s31, when the mobile terminal recognizes that the priority of the current voice call is set as the WiFi network priority, acquiring the current WiFi network signal of the mobile terminal;
s32, the mobile terminal judges whether the WiFi network signal is lower than a preset second preset signal threshold value;
and S33, if the WiFi network signal is lower than the second preset signal threshold, switching the VoWiFi call used by the current voice call of the mobile terminal to a VoLTE call or a VoNR call.
Specifically, when the mobile terminal recognizes that the priority of the current voice call is set as the WiFi network priority, that is, the WiFi network preferentially indicates that the default selected network call when the mobile terminal performs the voice call is a VoWiFi call, a current WiFi network signal of the mobile terminal is obtained, the mobile terminal determines whether the WiFi network signal is lower than a preset second preset signal threshold, and if the WiFi network signal is lower than the preset second preset signal threshold, it indicates that the quality of the current VoWiFi call is not good, so that if the WiFi network signal is lower than the second preset signal threshold (for example, the WiFi network signal is lower than-85 dBm), the VoWiFi call used by the current voice call of the mobile terminal is switched to a VoLTE or VoNR call, so that it can be ensured that a user performs a call on a network with the best network quality, the method can improve the call quality, reduce the call delay, and reduce the call drop rate and the call completing rate.
If the WiFi network signal is lower than the second preset signal threshold, the VoLTE or VoNR network signal strength is better at this time, and the VoWiFi call can be switched to the VoLTE or VoNR call, so that the call quality is not affected, and the call quality is better when the VoLTE or VoNR network is used, which provides better experience for the user. If the current WiFi network signal is larger than a second preset signal threshold, the current VoLTE or VoNR network is not enough in strength, the switching is not performed, the current WiFi network signal is obtained again and compared with the second preset signal threshold, and the switching of the call network is not performed until the WiFi network signal is lower than the second preset signal threshold.
Further, if the WiFi network signal is good, but the network transmission delay is large, because the bandwidth, the traffic volume, or the network congestion affects, the rate of signal transmission may be not good when the signal is good, and the quality of the VoWiFi call may also be affected, and at this time, the VoLTE or VoNR call is also preferably selected.
The invention switches the call mode according to the network signal, satisfies the detection of the mobile network and the WiFi network signal, better judges the current WiFi signal quality, and can play more shunting role and reduce the network load of an operator if the signal is better.
Further, based on the above network call switching method, as shown in fig. 5, the present invention further provides a network call switching system, wherein the network call switching system includes:
