The voice call method provided by the embodiment of the present application is described below in conjunction with FIG. 1. FIG. 1 is a schematic flow chart of the voice call method provided by the embodiment of the present application. As shown in FIG. 1, the embodiment of the present application provides a voice call method, including :

Step 101, periodically acquire the signal quality parameters of the first network, and determine based on the acquired signal quality parameters that it is necessary to generate a voice service down-standard operation identifier;

Wherein, the first network is a network that enables voice services supported by the terminal.

For example, the terminal registers to the 5G SA network, the 5G SA network also enables the VoNR voice service, the terminal also supports the VoNR function, and when the terminal needs to make a voice call, the VoNR call is made based on the 5G SA network, that is, the first network is 5G SA Network, the voice service request is a VoNR call request.

For example, the terminal is registered to the 5G SA network, and the 5G SA network also enables the VoNR voice service, but the terminal does not support the VoNR function. When the terminal needs to make a voice call, the terminal needs to fall back to the 4G network first, and then use the 4G network for VoLTE calls. , that is, in this case, the first network is a 4G network, and the voice service request is a VoLTE call request.

For example, if the terminal is registered to the 5G SA network, and the VoNR voice service is not enabled on the 5G SA network, but the terminal supports the VoNR function, and the VoLTE network is not enabled on the 4G network, then when the terminal needs to make a voice call, the terminal needs to fall back to 2G/3G In this case, the first network is a 2G/3G network, and the voice service request is a call request under the 2G/3G network.

Wherein, the acquisition period of the signal quality parameter of the first network can be a fixed value, or a flexible variable value, for example, setting the terminal to acquire the signal quality parameter of the first network every 10 minutes, or setting the terminal to obtain the signal quality parameter of the first network every 10 minutes. Get the signal quality parameters of the first network every 5 minutes during the time period, and get the signal quality parameters of the first network every 10 minutes during the valley period of voice calls, and also when the terminal's power is higher than 50%. The signal quality parameters of the first network are acquired every 5 minutes, and the signal quality parameters of the first network are acquired every 10 minutes when the power of the terminal is lower than 50%.

Optionally, the signal quality parameters include reference signal received power, reference signal received quality, and signal-to-interference-to-noise ratio, and any other parameters that can affect voice call quality.

It can be understood that when the signal quality of the network is poor, the probability of situations such as call drops and interruptions occurring when using the network for voice calls is also greater. In some embodiments, a specific threshold value is set , when it is detected that the value of the signal quality parameter of the first network is lower than the threshold value, a voice service downgrade operation flag is generated to notify the terminal to actively interrupt the first network for network fallback.

Among them, the voice service downgrade operation flag is used to instruct the terminal to actively interrupt the voice service of the first network and drop the network back to the second network whose voice quality is worse than that of the first network. After detecting this flag, the terminal does not need to Network switching is performed by relying on network equipment for redirection or switching, and the terminal actively interrupts the first network for network switching.

Step 102, receiving a voice service request based on the first network;

The voice service request may be initiated by the terminal, or passively initiated based on calls from other terminals. For example, the voice service request may be initiated by the user, or generated by other hardware devices or transmitted by software. For example, it may be through touch input, voice input, gesture input, visual input, brain-computer input, and the like.

The so-called hardware device generation can be information that the terminal is set to generate under certain conditions, such as generating an SOS (International Morse code rescue signal) voice service request when the cellular signal cannot be obtained beyond the preset time .

The so-called software transmission may be a voice service request triggered by a local third-party software of the terminal.

Step 103, detecting that the voice service downgrade operation identifier has been generated;

Among them, a voice service downgrade operation flag is set in advance, and the configuration of the voice service downgrade operation identifier of the flag is specified. For example, when the voice service downgrade operation needs to be performed, the flag on the flag is configured as 'true', when it is detected that the flag is configured as 'true', it is determined that the voice service downgrade operation identifier has been generated.

Step 104, interrupting the first network and searching for a second network;

Wherein, the second network may be the first network that can be registered and accessed by the terminal after the first network is interrupted, or the network with the best signal quality parameters among the several networks searched by the terminal after the first network is interrupted, or It can be the network that the terminal has registered in the current calling area, etc. in history.

In addition, the first network and the second network may be different networks of different operators, or different networks of the same operator.

Understandably, in this embodiment, the network standard of the second network is required to be lower than that of the first network, so that the stability and fluency of the subsequent voice call process can be ensured by independently lowering the voice quality requirement.

Wherein, the second network may be searched according to the 3GPP protocol.

For example, when the first network is a 5G SA network, the search priority of the second network is that the Long Term Evolution LTE network is higher than the Wideband Code Division Multiple Access W-CDMA network, and the W-CDMA network is higher than the Global System for Mobile Communications GSM network. . That is to say, the processing is performed according to a smooth transition search method of first searching for an LTE network, then searching for a W-CDMA network, and finally searching for a GSM network.

In this embodiment, during the process of searching for the second network, the terminal may search for the second network by means of cell reselection, and may also search by means of paging.

For example, in one embodiment, after the terminal obtains the current geographical location information, it first detects whether the broadcast control channel (Broadcast Control Channel, BCCH) data associated with the geographical location information is stored, and if it exists, first according to the stored BCCH Perform cell reselection. If it does not exist, you can search all the current RF channels of the terminal first, then read the received signal strength on each channel, calculate the average level, and then select the cell with the largest positive value as the resident Go first, and after camping in the cell, the terminal starts a random access procedure on a physical random access channel (Physical Random Access Channel, PRACH)/random access channel (Random Access Channel, RACH).

For example, in another embodiment, the terminal can monitor the physical downlink control channel (Physical Downlink Control Channel, PDCCH) physical channel, and then judge whether the network device is in the current paging cycle according to whether the PDCCH physical channel carries P-RNTI. Have you sent a paging message to yourself?

For example, in the paging process of the LTE network, the mobility management entity (Mobility Management Entity, MME) uses a paging message to initiate a paging process for each evolved base station (Evolved Node B, eNB), and each paging message carries a Information about the terminal being paged. After receiving the paging message, the eNB interprets the content, obtains the tracking area identifier list of the terminal, and performs air interface paging on the cells in the tracking area in its subordinate list, so that the terminal can Paging triggers the initiation of RRC connection establishment.

Step 105, switch to the second network, and establish a voice service connection with the target terminal corresponding to the voice service request in the second network, wherein the network standard of the second network is lower than that of the network of the first network format.

After finding the second network, the terminal actively disconnects from the first network, establishes a connection with the second network, and establishes a voice service connection supported by the second network with the target terminal.

In the voice call method provided in this embodiment, the terminal periodically obtains the signal quality parameters of the first network in advance, and marks the voice service down-standard operation identifier according to the signal quality parameters, so that the terminal receives the voice call based on the first network In the case of a service request, the first network can be actively interrupted when the voice service downgrade operation flag is detected, and the network call can be made after switching to the second network with a lower standard, thereby preventing the terminal from falling back during the call. In case of noise or interruption, the stability and success rate of the call are effectively improved.

In some embodiments, refer to FIG. 2 . FIG. 2 is a schematic flow diagram of a terminal in a VoNR voice call scenario under a 5G SA network. A terminal supporting the VoNR function registers with the 5G SA network with the VoNR network enabled after being turned on. In the case of the reduction function, continuously detect various indicators of the current 5G SA network, such as reference signal received power, reference signal reception quality, and signal-to-interference-noise ratio, and mark the call reduction mode according to the detection results, for example, according to the preset The threshold value of each indicator. When it is detected that the parameter value of an indicator meets the threshold value and the duration reaches Ts, the call reduction mode is marked as the 'true' mark. After the terminal enters the voice service scene, it judges Whether the current flag is 'true', if it is, it means that the voice service downgrade operation flag is detected, and the new air interface NR of the 5G SA network is immediately interrupted, and the call is switched to a low standard.

In some embodiments, if the current flag is 'false', it means that the quality of the current 5G SA network meets the voice call requirements, and calls can be made in the 5G SA network.

In some embodiments, if the terminal does not activate the autonomous drop-down function, the terminal directly dials in the 5G SA network after entering the voice service scenario, and then relies on network equipment to perform network fallback.

In some embodiments, after receiving the voice service request based on the first network, if the voice service downgrade operation identifier is not detected, reside in the first network, and the target corresponding to the voice service request in the first network The terminal establishes a voice service connection.

Among them, after the terminal resides on the first network and establishes a voice service, the network device side will decide whether the terminal needs to perform network fallback such as handover or redirection according to the network status reported by the terminal. In the case of the fallback instruction, switch to the network corresponding to the network fallback instruction and the target terminal corresponding to the voice service request to establish the voice service.

Therefore, after the terminal does not take the initiative to perform network switching, it can rely on network equipment to perform network fallback, thereby ensuring that the terminal can ensure that the user completes the voice call.

In some embodiments, before the periodic acquisition of the signal quality parameter of the first network, further includes:

Register with the first network, and determine the need to enter the voice service down-standard logic to judge the working status;

Enter the working state of logical judgment of voice service down-standard;

Periodically acquire the signal quality parameters of the first network.

Wherein, the logic judgment of voice service standard reduction refers to the logic of judging whether to perform voice service standard reduction operation.

For example, the identifiers for the logical judgment of the voice service downgrading mode are divided into "True" and "False". When the identifier of the voice service downgrading logic judgment is "True", it means that the terminal enters the working state of the voice service downgrading logic judgment. If the identifier of the voice service down-standard logic judgment is "False", it means that the terminal has not entered the voice service down-standard logic judgment working state.

Wherein, the working state may be indicated by the user, for example, after the terminal is registered to the first network, the user instructs the terminal to enter the working state of voice service down-regulation logic through key input, touch input, voice input and other means.

In addition, the working state can also be independently regulated by the terminal. For example, when the terminal detects that the number of calls on the terminal that is currently experiencing call drops or intermittent calls reaches a certain value, it will automatically enter the voice service reduction logic judgment working state. It can also be that when the terminal detects that the number of calls in all the voice services carried by the first network to which the terminal is currently connected has dropped calls or intermittent calls reaches a certain value, it will automatically enter the logic judgment work of the voice service reduction mode state.

The registration of the first network may be an initial registration at power-on, a mobile update registration, or a periodic registration, etc., and there is no limitation on this.

In this embodiment, after the terminal accesses the first network and enters into the working state of voice service down-standard logic judgment, it is periodically determined based on the signal quality parameters of the first network that a voice service down-standard operation identifier needs to be generated, thereby enabling When the signal quality parameters of the first network are relatively poor, generate a voice service downgrading operation flag to prepare for active low-standard switching in subsequent call scenarios, so as to avoid the occurrence of noise caused by the network drop of the terminal during the call Or intermittent and other conditions, effectively improving the stability and success rate of the call.

In some embodiments, the determination based on the acquired signal quality parameters that a voice service down-standard operation identifier needs to be generated includes:

It is determined that the value of at least one target parameter among the signal quality parameters is smaller than the preset limit value corresponding to the target parameter, and lasts for a preset duration.

For example, the signal quality parameter includes reference signal received power, reference signal received quality, and signal-to-interference-noise ratio, and any other parameter that can affect the quality of a voice call.

In some embodiments, since the value of any one of the signal quality parameters is relatively small, it will affect the smoothness of the call process, so as long as it is detected that there is a value of a target parameter that is less than its corresponding preset limit, it can be Generate an operation identifier for the down-standard voice service.

In some embodiments, since the signal state of the network will fluctuate constantly, in order to avoid frequent network switching, when the value of a certain target parameter is detected to be less than its corresponding preset limit, the monitoring of the target After the value of the parameter continues to be less than its corresponding preset limit for a preset period of time, an operation flag for downgrading the voice service is generated.

Wherein, the preset limit value may be a value configured in the terminal's non-volatile memory (NV). The signal quality parameter in the service scenario needs to be higher than the first limit value, and the signal quality parameter in the LTE service scenario needs to be higher than the second limit value, wherein the first limit value is greater than the second limit value.

In some embodiments, the preset limit value can also be generated based on a terminal-based custom control. For example, after the terminal is turned on and connected to the network, it can be set on the terminal setting interface based on the custom control, or on the SMS interface, or through the message push interface, etc. The configuration parameters input by the user can be obtained by means of other methods, for example, they can also be obtained through other hardware devices or software transmission.

The so-called hardware device generation can be the terminal is set to the preset limit value of the signal quality parameter corresponding to the voice service generated under certain conditions after the user enables a certain voice service function, for example, when the terminal detects It is generated based on the analysis of the signal quality of the call failure event when there is a call drop, noise or intermittent call failure event during the VoNR call.

It can be understood that the preset limit value refers to the case where the value of the signal quality parameter of the currently connected network is lower than a certain value, and the terminal will experience call drop, noise or intermittent during voice calls using the network. Wait for the call failure event, so in order to ensure that the above call failure event does not occur during the user call, it is required that the value of the signal quality parameter of the currently connected network needs to be greater than or equal to the specific value.

In the embodiment of this application, in order to ensure the smoothness of the user's call, after the terminal detects that the signal quality parameters do not meet the above requirements, the terminal generates a voice service downgrading operation flag to instruct the terminal to actively release the RRC of the first network after entering the call scene connection to interrupt the first network. For example, the terminal can send a release assistance instruction to the network device before starting a call. After the network device receives the release assistance instruction, since there is no uplink or downlink data between the current terminal and the network device, the network The device may immediately release the RRC connection.

In some embodiments, after registering the first network, it further includes:

If it is determined that it is not necessary to enter the voice service degraded logical judgment working state, reside in the first network, and establish a voice service connection with the target terminal corresponding to the voice service request in the first network.

Wherein, if the terminal does not need to enter the working state of voice service downgrading logic judgment, it may be that the network status of the first network can carry the voice service, or the user may instruct the terminal that the downgrading operation is not required. In this case, the terminal continues to Residing on the first network for voice calls.

In some embodiments, after the terminal resides on the first network and establishes a voice service, the network device side will decide whether the terminal needs to perform network fallback such as handover or redirection according to the network status reported by the terminal. In the case of a network fallback instruction sent by the user, switch to the third network corresponding to the network fallback instruction, and establish a voice service connection with the target terminal corresponding to the voice service request in the third network.

Therefore, after the terminal does not take the initiative to perform network switching, it can rely on network equipment to perform network fallback, thereby ensuring that the terminal can ensure that the user completes the voice call.

In some embodiments, the determination needs to enter the working state of logic judgment of the voice service down-standard mode, including:

The function switch for determining the logical judgment of the down-standard voice service is in the ON state.

If the function switch of the voice service down-standard logic judgment is in the off state, it is determined that it is not necessary to enter the voice service down-standard logic judgment working state.

The state of the function switch can be adjusted based on the obtained external information. For example, the terminal can adjust its switch state according to the user's touch input, voice input, gesture input, etc., and can also be based on the signal of the first network that the terminal is currently connected to. quality parameters to control.

The state of the function switch can also be regulated through the configuration information in the non-volatile memory NV, and can also be regulated through macro definitions. For example, in the early stage of terminal development, after the developer configures the terminal and connects to the network, the function switch is enabled by default. It is also possible to configure the function switch to be turned off by default after the terminal is turned on and connected to the network, and the function switch is adjusted to switch to the on state after receiving the user's turn-on command.

For example, in some embodiments, after the terminal is turned on and connected to the network, the network configuration interface is displayed. The function switch in the network configuration interface is not enabled by default. When the user operation that triggers the function switch is detected, the function switch is switched to on. state, where the user operation can be the user inputting a specific voice message, or any form of touch operation such as single-click, double-click, slide, etc., or press the volume control button and switch button at the same time, etc. .

In some embodiments, the determination needs to enter the working state of logic judgment of the voice service down-standard mode, including:

Based on the acquired voice service conditions supported by the first network, it is determined that it is necessary to enter into a voice service down-standard logical judgment working state.

Wherein, the voice service status may be the status of the voice service carried by the first network in a specific period of time in history. For example, if the terminal receives a voice service request from the first network at 10:00, it may obtain the first The status of voice services carried by the network during the time period from 10:00 to 11:00.

The voice service status may also be the status of the voice service up to the current time point after accessing the first network.

In this way, the terminal can automatically adjust the voice service down-standard logic to judge the working status according to the obtained voice service status of the first network, which improves the intelligence of the terminal, and thus avoids noise or noise caused by the network drop of the subsequent terminal during the call. Intermittent and other conditions, effectively improving the stability and success rate of the call.

Wherein, in some embodiments, the voice service status includes the voice service volume, and it is detected that the voice service volume supported by the first network is greater than the preset traffic volume, and it is determined that it is necessary to enter the voice service down-standard logical judgment working state.

It is detected that the traffic volume of the voice service supported by the first network is less than or equal to the preset traffic volume, and it is determined that it is not necessary to enter the voice service down-standard logical judgment working state.

Wherein, the traffic volume of the voice service refers to the number of terminals making voice calls in the first network.

Understandably, the capability of the first network to carry voice services is limited. If the current volume of voice services on the first network is high, the terminal may experience call drop or call failure during subsequent voice calls using the first network.
