In the embodiment of the present invention, the voice communication network includes an LTE communication network and an eMTC communication network, but is not limited thereto. In addition, the first voice transmission mode and the second voice transmission mode are applied to the terminal, the terminal can be a smart phone, a smart wearable device, a tablet, a computer, a workstation and the like which can realize voice communication, wherein the smart wearable device can be a smart watch, a smart bracelet and the like which can perform voice communication. The first voice transmission mode may be an eMTC/VoeMTC mode, and the second voice transmission mode may be an LTE/VoLTE mode, that is, when the terminal having the above two operation modes operates in the eMTC/VoeMTC mode, the transmitted voice signal is from or sent to the eMTC communication network, and when the terminal switches to the LTE/VoLTE mode, the transmitted voice signal is from or sent to the LTE communication network.
Specifically, a quality decision value of a voice signal in a current voice transmission mode is obtained, where the current voice transmission mode may be an eMTC/VoeMTC mode or an LTE/VoLTE mode. When the current voice transmission mode is an eMTC/VoeMTC mode, namely the terminal transmits voice signals through an eMTC communication network, and the quality judgment value is greater than a first preset threshold value, switching the current voice transmission mode from the eMTC/VoeMTC mode to an LTE/VoLTE mode, namely switching to the mode of transmitting the voice signals through the LTE communication network; and when the current voice transmission mode is an LTE/VoLTE mode, namely the terminal transmits voice signals through an LTE voice communication network, and the quality judgment value is greater than a second preset threshold value, switching the current voice transmission mode from the LTE/VoLTE mode to an eMTC/VoeMTC mode, namely switching to the mode of transmitting the voice signals through the eMTC communication network.

Example 2
As shown in fig. 2, which is a flowchart of a method for switching a voice transmission mode according to an embodiment of the present invention, the present embodiment is further improved on the basis of embodiment 1, and the improvement is that:
the step S11 includes the following sub-steps:
and a substep S11a of obtaining a signal quality value and a speech quality parameter value of the speech signal in the current speech transmission mode.
Substep S11b, when the signal quality value and the voice quality parameter value satisfy a third condition, performing weighted calculation on the signal quality value and the voice quality parameter value to obtain the quality decision value; wherein the third condition is: when the current voice transmission mode is a first voice transmission mode, the signal quality value is larger than a first threshold value and the voice quality parameter value is smaller than a second threshold value, or when the current voice transmission mode is a second voice transmission mode, the signal quality value is smaller than a third threshold value and the voice quality parameter value is larger than a fourth threshold value.
Specifically, in the embodiment of the present invention, the signal quality value may be an RSRP value, and the voice signal quality parameter value includes one or any combination of the following: the packet loss rate, the time delay and the jitter, and the signal quality value and the signal quality parameter value are not limited to the above and may be selected according to actual situations.
When the current voice transmission mode is an eMTC/VoeMTC mode, the terminal acquires voice signals from an eMTC communication network through the eMTC/VoeMTC mode, and when the RSRP value of the voice signals is larger than a first threshold value and the voice quality parameter value is smaller than a second threshold value, the terminal performs weighted calculation on the signal quality value and the voice quality parameter value to acquire a quality judgment value.
The voice quality parameter value may be a packet loss rate, a time delay, or jitter, or a combined value of a packet loss rate and a time delay, a combined value of a packet loss rate and a jitter, a combined value of a time delay and a jitter, or a combined value of a packet loss rate, a time delay, and a jitter, for example, when the RSRP value is greater than a first threshold and the packet loss rate is less than a second threshold, the RSRP value and the packet loss rate are weighted to obtain a quality decision value, or when the RSRP value is less than the first threshold and the combined value of the packet loss rate, the time delay, and the jitter is less than the second threshold, the combined value of the RSRP value and the packet loss rate, the time delay, and the jitter is weighted to obtain a quality decision value, which may be specifically selected according to an actual situation, and specific implementation manners of the voice quality parameter value are not described in detail herein. In addition, the signal quality on the eMTC communication network is said to be better when the RSRP value is greater than the first threshold value, and the VoeMTC voice quality is said to be better when the voice quality parameter value is less than the second threshold value.
Then, when performing weighting calculation, selecting weighting factors, for example, selecting the weighting factor of the RSRP value as 40%, if the voice quality parameter value is a combined value of the packet loss rate, the time delay and the jitter, selecting the weighting factor of the packet loss rate as 20%, selecting the weighting factor of the time delay as 20%, and selecting the weighting factor of the jitter as 20%, when the quality decision value obtained after the weighting calculation is greater than a first preset threshold (for example, 60%), switching the terminal from the eMTC/VoeMTC mode to the LTE/VoLTE mode, and transmitting high-definition VoLTE voice signals by using an LTE communication network, thereby improving the definition and fidelity of voice and improving user experience; and when the quality decision value obtained after the weighting calculation is not greater than a first preset threshold (for example, 60%), the terminal maintains the working state of the eMTC/VoeMTC mode.
And when the current voice transmission mode is the LTE/VoLTE mode, the terminal acquires voice signals from the LTE communication network through the LTE/VoLTE mode, and when the RSRP value of the voice signals is smaller than a third threshold value and the voice quality parameter value is larger than a fourth threshold value, the terminal performs weighted calculation on the signal quality value and the voice quality parameter value to acquire a quality judgment value.
Specifically, the voice quality parameter value may be a packet loss ratio, a time delay or a jitter, or a combined value of a packet loss ratio and a time delay, a combined value of a packet loss ratio and a jitter, a combined value of a time delay and a jitter, or a combined value of a packet loss ratio, a time delay and a jitter, for example, when the RSRP value is smaller than a third threshold and the packet loss ratio is larger than a fourth threshold, the RSRP value and the packet loss ratio are weighted to obtain a quality decision value, or when the RSRP value is smaller than the third threshold and the combined value of the packet loss ratio, the time delay and the jitter is larger than the fourth threshold, the RSRP value and the combined value of the packet loss ratio, the time delay and the jitter are weighted to obtain a quality decision value, which may be specifically selected according to actual conditions, and specific implementation manners of the voice quality parameter value are not described in detail herein. In addition, when the RSRP value is less than the third threshold value, it indicates that the signal quality on the LTE communication network is degraded, and when the voice quality parameter value is greater than the fourth threshold value, it indicates that the VoLTE voice quality is degraded.
Then, when performing weighting calculation, selecting weighting factors, for example, selecting the weighting factor of the RSRP value as 40%, if the voice quality parameter value is a combined value of the packet loss rate, the time delay and the jitter, respectively selecting the weighting factor of the packet loss rate as 20%, the weighting factor of the time delay as 20%, and the weighting factor of the jitter as 20%, when the quality decision value obtained after the weighting calculation is greater than a second preset threshold (for example, 60%), switching the terminal from the LTE/VoLTE mode to the eMTC/VoeMTC mode, and transmitting a low-definition VoeMTC voice signal by using an eMTC communication network, thereby ensuring the fluency of voice communication and improving user experience; and when the quality decision value obtained after the weighting calculation is not greater than a second preset threshold (such as 60%), the terminal keeps the working state of the LTE/VoLTE mode.
It should be noted that, the first preset threshold and the second preset threshold may be the same, for example, both are 60%, or the first preset threshold may be 70%, and the second preset threshold may be 75%, which may be specifically selected according to actual situations, and is not limited to this.
Therefore, in the embodiment of the invention, by realizing the switching between the LTE/VoLTE mode and the eMTC/VoeMTC mode, when the signal quality and the voice quality are both good, the high-definition VoLTE voice can be switched to use; when the LTE communication network is used, the signal quality and the voice quality are poor, for example, a building is shielded, a basement is shielded, the VoeMTC voice can be switched to be used, the communication coverage range of the voice signals can be effectively extended, when hardware or software on the terminal for realizing any voice transmission mode breaks down and cannot be communicated, the interruption of the voice signals can be avoided through switching, and the user experience is further improved.

When a terminal 2 adopts an eMTC module 21 to transmit a voice signal, namely, the terminal passes through the eMTC module 21 adopts an eMTC/VoeMTC mode to obtain the voice signal from the eMTC communication network, the signal quality detection module 231 obtains an RSRP value of the voice signal obtained by the eMTC module 21, the weighting submodule 233 is used for weighting and calculating the RSRP value and the voice quality parameter value to obtain the quality judgment value when the current voice transmission module is the eMTC module, the RSRP value is greater than a first threshold value and the voice quality parameter value is less than a second threshold value.
Specifically, the voice quality parameter value may be a packet loss ratio, a time delay or a jitter, or a combined value of a packet loss ratio and a time delay, a combined value of a packet loss ratio and a jitter, a combined value of a time delay and a jitter, or a combined value of a packet loss ratio, a time delay and a jitter, for example, when the RSRP value is greater than a first threshold and the packet loss ratio is less than a second threshold, the RSRP value and the packet loss ratio are weighted to obtain a quality decision value, or when the RSRP value is less than the first threshold and the combined value of the packet loss ratio, the time delay and the jitter is less than the second threshold, the RSRP value and the combined value of the packet loss ratio, the time delay and the jitter are weighted to obtain a quality decision value, which may be specifically selected according to actual conditions, and specific implementation manners of the voice quality parameter value are not described in detail herein. In addition, the signal quality on the eMTC communication network is said to be better when the RSRP value is greater than the first threshold value, and the VoeMTC voice quality is said to be better when the voice quality parameter value is less than the second threshold value.
Then, when performing weighting calculation, selecting weighting factors, for example, selecting the weighting factor of the RSRP value as 40%, if the voice quality parameter value is a combined value of the packet loss rate, the time delay and the jitter, respectively selecting the weighting factor of the packet loss rate as 20%, the weighting factor of the time delay as 20%, and the weighting factor of the jitter as 20%, when the quality decision value obtained after the weighting calculation is greater than a first preset threshold (for example, 70%), switching the terminal from the eMTC module to the LTE module to transmit the voice signal, where the voice signal is a high-definition VoLTE voice signal transmitted by the LTE communication network, thereby improving the definition and fidelity of voice, and improving user experience; and when the quality decision value obtained after the weighting calculation is not greater than a first preset threshold (for example, 70%), the terminal keeps adopting the eMTC module to transmit the voice signal, that is, the terminal keeps the working state of the eMTC/VoeMTC mode.
Further, when the terminal 2 uses the LTE module 22 to transmit the voice signal, that is, the terminal 2 obtains the voice signal from the LTE communication network through the LTE module 22 in the LTE/VoLTE mode, the signal quality detection module 231 obtains an RSRP value of the voice signal obtained by the LTE module 22, and the weighting sub-module 233 performs weighting calculation on the RSRP value and the voice quality parameter value to obtain the quality decision value when the current voice transmission module is the LTE module 22, the RSRP value is smaller than a third threshold value, and the voice quality parameter value is larger than a fourth threshold value.
Specifically, the voice quality parameter value may be a packet loss ratio, a time delay or a jitter, or a combined value of a packet loss ratio and a time delay, a combined value of a packet loss ratio and a jitter, a combined value of a time delay and a jitter, or a combined value of a packet loss ratio, a time delay and a jitter, for example, when the RSRP value is smaller than a third threshold and the packet loss ratio is larger than a fourth threshold, the RSRP value and the packet loss ratio are weighted to obtain a quality decision value, or when the RSRP value is smaller than the third threshold and the combined value of the packet loss ratio, the time delay and the jitter is larger than the fourth threshold, the RSRP value and the combined value of the packet loss ratio, the time delay and the jitter are weighted to obtain a quality decision value, which may be specifically selected according to actual conditions, and specific implementation manners of the voice quality parameter value are not described in detail herein. In addition, when the RSRP value is less than the third threshold value, it indicates that the signal quality on the LTE communication network is degraded, and when the voice quality parameter value is greater than the fourth threshold value, it indicates that the VoLTE voice quality is degraded.
Then, when performing weighting calculation, selecting weighting factors, for example, selecting the weighting factor of the RSRP value as 40%, if the voice quality parameter value is a combined value of the packet loss rate, the time delay and the jitter, respectively selecting the weighting factor of the packet loss rate as 20%, the weighting factor of the time delay as 20%, and the weighting factor of the jitter as 20%, when the quality decision value obtained after the weighting calculation is greater than a second preset threshold (for example, 75%), switching the terminal from the LTE module 22 to the eMTC module 21 to transmit a voice signal, where the voice signal is a low-definition VoeMTC voice signal transmitted by the eMTC communication network, so as to ensure the fluency of voice communication and improve user experience; and when the quality decision value obtained after the weighting calculation is not greater than a second preset threshold (for example, 75%), the terminal keeps the working state of the LTE/VoLTE mode.
It should be noted that, the first preset threshold and the second preset threshold may be the same, for example, both are 60%, or the first preset threshold may be 70%, and the second preset threshold may be 75%, which may be specifically selected according to actual situations, and is not limited to this.
Therefore, in the embodiment of the invention, the terminal adopts the LTE module and the eMTC module to realize the switching between the LTE/VoLTE mode and the eMTC/VoeMTC mode, and when the signal quality and the voice quality are both good, the LTE module can be switched to transmit high-definition VoLTE voice; and when using LTE communication network the signal quality is not good and the voice quality is not good, for example there is the building to shelter from, the basement etc. can switch to adopting the eMTC module to transmit the VoeMTC pronunciation, can effectively extend voice signal's communication coverage, when hardware or software that realize arbitrary voice transmission mode on the terminal broke down and lead to unable adoption corresponding voice communication module to carry out voice communication when for example LTE module or eMTC module damage, can avoid voice signal's interrupt through switching voice transmission module, the continuity of pronunciation has been guaranteed, user experience has further been improved. And moreover, the eMTC low-definition voice is adopted, the service time of the smart phone is prolonged, and the cruising ability is improved.
