- FIG. 1 is a flowchart of a preferred embodiment of a method for switching an IMS voice call network according to an embodiment of the present invention.
- the IMS voice call network switching method includes the following steps:
- Step S100 When the mobile terminal is in the IMS voice call, identify the call network currently used by the mobile terminal.
- the step S100 specifically includes: [0077] Step S101: The mobile terminal receives an operation instruction, and activates an IMS voice call function.
- Step S102 Acquire and identify a call network currently used by the mobile terminal.
- the present invention presets a first signal threshold for determining whether to switch the call network from the VoLTE network to the VoWiR network; the first signal threshold Indicates the signal strength of the current VoWiFi network; and preset a second signal threshold for determining whether to switch the call network from the VoWiFi network to the VoLTE network; the second signal threshold indicates the signal strength of the current VoWiR network.
- the voice network can be switched only when the signal value of the VoLTE network or the VoWiFi network reaches a certain strength, so as to reduce the situation of switching when searching for a certain network, and ensuring that the call quality is not affected. It is convenient for the user to use.
- the super-turn is a Fibonacci sequence value of the number of handovers. Since the super-turn is based on the Fibonacci sequence, the value is [1, 1, 2, 3, 5, 8, 13, 21, 34....], thus making the embodiment of the present invention in a call
- the network environment is not good, and the ultra-complex will be significantly extended with the number of handovers, thereby reducing the frequent switching of the call network, improving the call quality, reducing the power consumption of the mobile terminal, and bringing convenience to the user.

- the call network is a VoWiFi network or a VoLTE network.
- Step S200 When the call network is a VoLTE network, and the usage of the VoLTE network is greater than the inter-turn time, the current call center of the mobile terminal is obtained after the current VoWiFi network signal strength reaches a preset first signal threshold. The VoLTE network used is switched to a VoWiFi network.
- the step S200 specifically includes:
- Step S201 When it is identified that the call network currently used by the mobile terminal is a VoLTE network, calculate a usage time of the VoLTE network, and determine whether the usage time of the VoLTE network is greater than a maximum time interval;

- Step S203 When the signal strength of the current VoWiFi network is greater than or equal to the first signal threshold, The VoLTE network used by the mobile terminal to switch the current call is switched to the VoWiFi network; otherwise, step S202 is repeatedly performed.
- the usage of the VoLTE network is calculated according to a preset super-inference algorithm, and whether the usage time of the VoLTE network is greater than Super room. Specifically, the mobile terminal acquires the current time of the current call, the time of the last call network handover, and the number of handovers, and calculates the difference between the current time and the last call network handover time, and the difference between the time is the VoLTE network. Use the daytime.
- the usage time of the VoLTE network when the usage time of the VoLTE network is greater than or equal to the inter-turn time, it indicates that the switching condition of the call network is satisfied. If the usage of the VoLTE network is less than the inter-turn time, the handover condition is not satisfied, that is, the handover period has not yet arrived, and it is necessary to wait for a certain period of time, and then continue to acquire the current handover and the last call network handover. In the daytime and the number of handovers, the usage and time of the VoWiFi network are calculated again, and compared until the usage of the VoWiFi network is greater than the time.
- the signal strength of the current VoWiFi network is further obtained and compared with a preset first signal threshold. Due to the small coverage of the WiFi network, especially for the average home user, a WiFi signal is basically used, and the coverage of the single WiFi signal is smaller, and the user may accidentally get out of the WiFi signal during the IMS voice call. The scope. In order to prevent the mobile terminal from switching to a VoWiFi network with a bad WiFi signal, the first signal threshold is set to help the mobile terminal determine whether to perform the handover.
- the signal of the current VoWiFi network is greater than or equal to the first signal threshold, it indicates that the signal strength of the VoWiFi network is better, and the VoLTE network can be switched to the VoWiFi network, which not only does not affect the call quality, but also uses the VoWiFi network to have better call quality. Give users a better experience. If the current VoWiFi network signal is smaller than the first signal threshold, it indicates that the current VoWiFi network strength is insufficient, then no handover is performed, and the current VoWiFi network strength is acquired again and compared with the first signal threshold until the signal of the VoWiFi network is greater than or equal to the first.
- the signal threshold ⁇ is used to switch the call network.
- the number of handovers is incremented by 1, and the handover time of the conference network is recorded. That is to say, every time the VoLTE network successfully switches to the VoWiFi network, the number of handovers is increased by 1, and the current network is switched to the time interval, so that step S201 is repeated afterwards, and the last handover time and handover can be obtained. Times Number.
- Step S300 When the call network is a VoWiFi network, and the current VoLTE network signal strength reaches a preset second signal threshold ⁇ ; switching the VoWiFi network used by the mobile terminal for the current call to the VoLTE network.
- the step S300 specifically includes:
- Step S301 When it is recognized that the call network currently used by the mobile terminal is a VoWiFi network, the shell 1J obtains the signal strength of the current VoLTE network, and compares with a preset second signal threshold.
- Step S302 When the signal strength of the current VoLTE network is greater than or equal to the second signal threshold, the VoWiFi network used by the current call of the mobile terminal is switched to the VoLTE network; otherwise, step S301 is repeatedly performed.
- the signal strength of the current VoLTE network is obtained and compared with a preset second signal threshold. Since the VoLTE network is also affected by the environment, the signal strength is also weak and weak. Therefore, in order to better help the mobile terminal to determine whether it is necessary to switch the call network from the VoWiFi network to the VoLTE network, a second signal threshold is set. . When the current VoLTE network signal is greater than or equal to the second signal threshold, it indicates that the VoLTE network signal is better, and the VoLTE network can be switched to the VoWiFi network, thereby improving the quality of the call and providing a better experience for the user.
- the signal of the current VoLTE network is smaller than the second signal threshold ⁇ , it indicates that the signal strength of the ⁇ VoLTE network is insufficient, then no handover is performed, and the current VoLTE network strength is continuously acquired and compared with the second signal threshold until the VoLTE network

[0086] 步骤 S203、 当当前 VoWiFi网络的信号强度大于或等于第一信号阈值吋, 则将
所述移动终端当前通话所使用的 VoLTE网络切换成 VoWiFi网络; 否则, 则重复 执行步骤 S202。
[0087] 具体实施吋, 当移动终端识别出当前所使用的通话网络为 VoLTE网络吋, 则根 据预设的超吋算法, 计算 VoLTE网络的使用吋间, 并判断 VoLTE网络的使用吋 间是否大于超吋吋间。 具体地, 移动终端获取当前吋间、 上一次通话网络切换 的吋间以及切换次数, 计算当前吋间与上一次通话网络切换吋间的吋间差值, 所述吋间差值为 VoLTE网络的使用吋间。 将 VoLTE网络的使用吋间与超吋吋间 进行比较, 当 VoLTE网络的使用吋间大于或等于超吋吋间吋, 则说明满足通话 网络的切换条件。 若 VoLTE网络的使用吋间小于超吋吋间吋, 则并不满足切换 条件, 也就是说切换吋间还没到, 还需等待一定吋间, 则继续获取当前吋间、 上一次通话网络切换的吋间以及切换次数, 再次计算 VoWiFi网络的使用吋间和 超吋吋间, 并进行比较, 直到 VoWiFi网络的使用吋间大于超吋吋间。
[0088] 当满足通话网络切换条件吋, 进一步获取当前 VoWiFi网络的信号强度, 并与 预设的第一信号阈值比较。 由于 WiFi网络的覆盖范围较小, 特别是一般家庭用 户, 基本是使用一个 WiFi信号, 而单个 WiFi信号覆盖的范围更加小, 用户在进 行 IMS语音通话的过程中一下不小心就会走出 WiFi信号覆盖的范围。 为了避免移 动终端切换至 WiFi信号不好的 VoWiFi网络, 因此设置所述第一信号阈值, 帮助 移动终端判断是否进行切换。 若当前 VoWiFi网络的信号大于或等于第一信号阈 值, 则说明此吋 VoWiFi网络信号强度较佳, 可以将 VoLTE网络切换至 VoWiFi网 络, 不但不会影响通话质量, 而且使用 VoWiFi网络通话质量更加好, 给用户更 好的体验。 如果当前 VoWiFi网络的信号小于第一信号阈值, 则说明当前 VoWiFi 网络强度不够, 则不进行切换, 并再次获取当前 VoWiFi网络强度并与第一信号 阈值比较, 直到 VoWiFi网络的信号大于或者等于第一信号阈值吋, 才进行通话 网络的切换。
[0089] 在一些实施例中, 当所述移动终端的通话网络从 VoLTE网络切换成 VoWiFi网 络后, 切换次数加 1, 并记录此吋通话网络的切换吋间。 也就是说, VoLTE网络 每成功切换至 VoWiFi网络, 就会在切换次数上加 1, 并且将当前网络切换吋间记 录, 以便在之后重复进行步骤 S201吋, 可以获取到上一次切换吋间以及切换次
数。
[0090] 步骤 S300、 当通话网络为 VoWiFi网络, 且当前 VoLTE网络信号强度达到预设 的第二信号阈值吋; 将移动终端当前通话所使用的 VoWiFi网络切换成 VoLTE网 络。
[0091] 在一些实施例中, 所述步骤 S300具体包括:
[0092] 步骤 S301、 当识别出所述移动终端当前所使用通话网络是 VoWiFi网络吋, 贝 1J 获取当前 VoLTE网络的信号强度, 并与预设的第二信号阈值比较;
[0093] 步骤 S302、 当当前 VoLTE网络的信号强度大于或等于第二信号阈值吋, 则将所 述移动终端当前通话所使用的 VoWiFi网络切换成 VoLTE网络; 否则, 重复执行 步骤 S301。
[0094] 具体实施吋, 当移动终端识别出当前通话网络使用的是 VoWiFi网络吋, 则获 取当前 VoLTE网络的信号强度, 并与预设的第二信号阈值比较。 由于 VoLTE网 络同样也会受到环境的影响, 信号强度也吋强吋弱, 因此, 为了更好的帮助移 动终端确定是否需要将通话网络从 VoWiFi网络切换至 VoLTE网络, 因此, 设置 一第二信号阈值。 当当前 VoLTE网络的信号大于等于第二信号阈值吋, 则说明 此吋 VoLTE网络信号较佳, 可以将 VoLTE网络切换至 VoWiFi网络, 以此改善通 话质量, 给用户更好的体验。 同样的, 当当前 VoLTE网络的信号小于第二信号 阈值吋, 则说明此吋 VoLTE网络信号强度不够, 则不进行切换, 并继续获取当 前 VoLTE网络强度并与第二信号阈值比较, 直到 VoLTE网络的信号大于或者等 于第二信号阈值吋, 才进行通话网络的切换。 由此, 有效避免了移动终端在 IMS 语音通话的过程中 VoLTE与 VoWiFi的频繁切换。
