In some embodiments, the network signals in some areas are weak due to the coverage of some network base stations, and a user usually needs to perform a fallback means such as redirection or handover by using a network device to successfully complete the call in the voice call process under the network signals.

For example, a New air interface of 5G carries a Voice over New Radio (VoNR) service, where the New air interface carries a Voice (VoNR) service directly from a 5G network to an end, and in this manner, to ensure continuity of a Voice call, the network device may determine, according to a network measurement report reported by the terminal, whether the Voice call of the terminal device needs to be switched from 4G to 5G.

That is, the terminal supports the VoNR function, and when the 5G SA network registered by the terminal also starts the VoNR service, the terminal can directly perform the voice service based on the NR network without falling back to a Long Term Evolution (LTE) network, thereby obtaining a higher quality voice service experience and a higher rate data service experience.

A voice call method provided in an embodiment of the present application is described below with reference to fig. 1, where fig. 1 is a schematic flowchart of the voice call method provided in the embodiment of the present application, and as shown in fig. 1, the embodiment of the present application provides a voice call method, including:

step 101, periodically acquiring a signal quality parameter of a first network, and determining a voice service downgrading type operation identifier to be generated based on the acquired signal quality parameter;

the first network is a network for starting a voice service supported by the terminal.

For example, the terminal is registered to the 5G SA network, the 5G SA network also opens the VoNR voice service, the terminal also supports the VoNR function, and when the terminal needs to perform a voice call, the terminal performs a VoNR call based on the 5G SA network, that is, the first network is the 5G SA network, and the voice service request is a VoNR call request.

For example, the terminal is registered in the 5G SA network, the 5G SA network also starts the volr voice service, but the terminal does not support the volr function, and when the terminal needs to perform a voice call, the terminal needs to fall back to the 4G network first and then perform a VoLTE call using the 4G network, that is, in this case, the first network is the 4G network, and the voice service request is a VoLTE call request.

For example, the terminal is registered in the 5G SA network, the 5G SA network does not start the VoNR voice service, but the terminal supports the VoNR function, and the 4G network does not start the VoLTE network, so that when the terminal needs to perform a voice call, the terminal needs to fall back to the 2G/3G network to perform the voice call, in this case, the first network is the 2G/3G network, and the voice service request is a call request in the 2G/3G network.

The acquisition period of the signal quality parameter of the first network may be a fixed value, or may be a flexible variable value, for example, the terminal is set to acquire the signal quality parameter of the first network every 10 minutes, the terminal may also be set to acquire the signal quality parameter of the first network every 5 minutes in a voice call peak period time period, the signal quality parameter of the first network every 10 minutes in a voice call valley period time period, the signal quality parameter of the first network may also be acquired every 5 minutes when the power of the terminal is higher than 50%, the signal quality parameter of the first network is acquired every 10 minutes when the power of the terminal is lower than 50%, and the like.

Alternatively, the signal quality parameter includes any parameter that may affect the quality of the voice call, such as the received power of the reference signal, the received quality of the reference signal, and the signal to interference plus noise ratio.

It can be understood that, when the signal quality of the network is poor, the probability that a call drop, an interruption, or the like occurs when the network is used for voice call is also higher, in some embodiments, a specific threshold value is set, and 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 drop operation identifier is generated to notify the terminal to actively interrupt the first network for network drop.

The voice service downgrading operation identifier is an identifier used for indicating the terminal to actively interrupt the voice service of the first network and drop the network back to the second network with the voice quality worse than that of the first network, after the terminal detects the identifier, network switching is carried out without depending on redirection or switching of network equipment, and the terminal actively interrupts the first network to carry out network switching.

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

the voice service request may be initiated by the terminal actively, or may be initiated passively based on a call of another terminal, for example, the terminal actively initiates a mode that is input by a user, or generated by another hardware device or transmitted by software. For example, by touch input, voice input, gesture input, visual input, brain-computer input, etc.

The so-called hardware device generation may be information that the terminal is set to generate under certain conditions, such as a SOS (international morse code distress signal) voice service request generated in the case where a cellular signal cannot be acquired over a preset time, and the like.

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

103, detecting that the voice service downgrade type operation identifier is generated;

the method includes the steps of presetting a voice service downgrading operation marking bit, and specifying the configuration of a voice service downgrading operation identifier of the marking bit, for example, when voice service downgrading operation needs to be executed, configuring an identifier on the marking bit to be 'tune', and when the fact that the marking is configured to be 'tune' is detected, judging that the voice service downgrading operation identifier is generated.

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

the second network may be a network which can be registered and accessed firstly after the terminal interrupts the first network, a network which has the highest signal quality parameter in a plurality of networks searched after the terminal interrupts the first network, a network which has been registered by the terminal in the current call area, or the like.

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

It can be understood that, in the embodiment, the network standard of the second network is required to be lower than that of the first network, so that the stability and the fluency of the subsequent voice call process are ensured by autonomously reducing the voice quality requirement.

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

For example, in the case where the first network is a 5G SA network, the priority of the search for the second network is that the LTE network is higher than the wcdma W-CDMA network, which is higher than the GSM network. Namely, the smooth transition searching mode of searching the LTE network, searching the W-CDMA network and searching the GSM network is adopted for processing.

In this embodiment, in the process of searching for the second network, the terminal may search for the second network in a cell reselection manner, and may also search for the second network in a paging manner.

For example, in an embodiment, after acquiring current geographical location information, a terminal first detects whether Broadcast Control Channel (BCCH) data associated with the geographical location information is stored, if so, performs cell reselection according to the stored BCCH, if not, may first search all current RF channels of the terminal, then reads received signal strength on each Channel, calculates an average level, then selects a cell with a largest positive value as a camping first, and after camping in the cell, the terminal starts a Random Access procedure on a Physical Random Access Channel (PRACH)/Random Access Channel (RACH).

For example, in another embodiment, the terminal may monitor a Physical Downlink Control Channel (PDCCH) Physical Channel, and then determine whether the network device sends the paging message to the terminal in the current paging cycle according to whether the PDCCH Physical Channel carries the P-RNTI.

For example, in the LTE network paging process, a Mobility Management Entity (MME) initiates a paging process to each Evolved Node B (eNB) using a paging message, where each paging message carries information of a paged terminal, and after receiving the paging message, the eNB interprets the content of the paging message to obtain a tracking area identifier list of the terminal, and performs air interface paging on a cell of a tracking area in a subordinate list thereof, so that the terminal triggers initiation of RRC connection establishment based on the paging.

And 105, switching to the second network, and establishing voice service connection with the target terminal corresponding to the voice service request in the second network, wherein the network type of the second network is lower than that of the first network.

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

According to the voice call method provided by the embodiment, the terminal periodically acquires the signal quality parameter of the first network in advance, and marks the voice service system-reducing operation identifier according to the signal quality parameter, so that the terminal can actively interrupt the first network when detecting the voice service system-reducing operation identifier under the condition that the terminal receives a voice service request based on the first network, and then performs network call after switching to the low-system second network, thereby avoiding the situations of noise or interruption and the like caused by network fall-back of the terminal in the call process, and effectively improving the stability and success rate of the call.

In some embodiments, referring to fig. 2, fig. 2 is a schematic flow diagram of a terminal in a VoNR voice call scenario in a 5G SA network, after the terminal supporting the VoNR function is powered on, the terminal registers to the 5G SA network which starts the VoNR network, and when the terminal starts an autonomous degradation function, the terminal continuously detects various indexes of the current 5G SA network, such as reference signal received power, reference signal received quality, and signal to interference and noise ratio, and performs call degradation type marking according to a detection result, for example, according to a preset threshold value of each index, when it is detected that a parameter value of one index satisfies the threshold value and a duration time reaches Ts, the call degradation type is marked as a 'tune' identifier, after the terminal enters a voice service scenario, the terminal determines whether the current identifier is 'tune', if it is, it indicates that a voice service degradation type operation identifier is detected, immediately interrupts a new air interface NR of the 5G SA network, and switches to a low dialing type.

In some embodiments, if the current identifier is 'false', it is characterized that the quality of the current 5G SA network meets the voice call requirement, and then the call can be made in the 5G SA network.

In some embodiments, if the terminal does not start the autonomous degradation function, the terminal directly dials in the 5G SA network after entering the voice service scene, and subsequently performs network fallback on the terminal by using the network device.

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

After the terminal resides in the first network to establish the voice service, the network equipment end can decide whether the terminal needs to perform network fallback such as switching or redirection according to the network state reported by the terminal, and under the condition of receiving a network fallback indication sent by the network equipment, the terminal is switched to a network corresponding to the network fallback indication and a target terminal corresponding to the voice service request to establish the voice service.

Therefore, the terminal can rely on the network equipment to perform network fallback after not actively performing network switching, so that the terminal can ensure that a user can complete voice communication.

In some embodiments, before periodically acquiring the signal quality parameter of the first network, the method further includes:

entering a voice service downgrading logic judgment working state;

periodically acquiring a signal quality parameter of the first network.

The voice service system-down logic judgment refers to logic for judging whether voice service system-down operation needs to be executed.

For example, the identifier determined by the voice service downgrading logic is divided into "True" and "False", when the identifier determined by the voice service downgrading logic is "True", the terminal is characterized to enter the voice service downgrading logic determination working state, and if the identifier determined by the voice service downgrading logic is "False", the terminal is not characterized to enter the voice service downgrading logic determination working state.

The working state may be indicated by a user, for example, after the terminal is registered in the first network, the user indicates the terminal to enter the voice service downgrading logic to determine the working state through key input, touch input, voice input, and the like.

In addition, the working state may be independently controlled by the terminal, for example, the terminal automatically enters the voice service drop type logic judgment working state when monitoring that the number of times of call in the situations of call drop, interruption and the like currently occurring in the terminal reaches a certain specific value, or the terminal automatically enters the voice service drop type logic judgment working state when monitoring that the number of times of call in the situations of call drop, interruption and the like occurring in all voice services borne by the first network currently connected to the terminal reaches a certain specific value.

The registration of the first network may be initial registration at power-on, registration for mobile update, periodic registration, or the like, which is not limited.

In the embodiment, after the terminal is accessed to the first network, in the working state of the voice service downgrading logic judgment, the voice service downgrading operation identifier which needs to be generated is determined periodically based on the signal quality parameter of the first network, so that when the signal quality parameter of the first network is poor, a voice service downgrading operation identifier is generated to prepare for actively carrying out low-standard switching in a subsequent conversation scene, thereby avoiding the situations of noise or interruption and the like caused by network fallback of the terminal in the conversation process, and effectively improving the stability and the success rate of conversation.

In some embodiments, the determining, based on the obtained signal quality parameter, that a voice service downgrading operation identifier needs to be generated includes:

For example, the signal quality parameters include reference signal received power, reference signal received quality, and signal to interference and noise ratio, which may affect the quality of the voice call.

In some embodiments, as the smoothness of the call process is affected when the value of any one of the signal quality parameters is smaller, the voice service downgrading operation identifier can be generated as long as it is detected that the value of an item target parameter is smaller than the corresponding preset limit.

In some embodiments, since the signal state of the network may fluctuate constantly, in order to avoid frequent switching of the network, when it is detected that the value of a certain item target parameter is smaller than the corresponding preset limit, after the value of the target parameter is monitored to be continuously smaller than the corresponding preset limit for a preset duration, the voice service degradation operation identifier is regenerated.

The preset limit may be a value configured in a non-volatile memory (NV) of the terminal, for example, a limit configured by a developer in advance in various voice service scenarios during research and development, for example, a signal quality parameter configured in a VoNR service scenario needs to be higher than a first limit, and a signal quality parameter configured in an LTE service scenario needs to be higher than a second limit, where the first limit is greater than the second limit.

In some embodiments, the preset limit may also be generated by a user-defined control based on the terminal, for example, after the terminal is powered on and accesses the network, the configuration parameters input by the user are acquired in a terminal setting interface, a short message interface, or a message pushing interface or the like, for example, the configuration parameters may also be generated by other hardware devices or obtained by software transmission.

The generation of the hardware device may be that the terminal is set to be a preset limit value of a signal quality parameter corresponding to a certain voice service generated under a certain condition after a user enables a certain voice service function, for example, the terminal is generated based on an analysis of a signal quality of a call failure event when monitoring that a call drop, a noise or an intermittent call failure event occurs in a VoNR call process.

It can be understood that, when the preset limit refers to that the value of the signal quality parameter of the currently accessed network is lower than a certain value, a call failure event such as call drop, noise or interruption may occur during a voice call using the network by the terminal, and therefore, in order to ensure that the call failure event does not occur during a user call, the value of the signal quality parameter of the currently accessed network needs to be greater than or equal to the certain value.

In order to guarantee the fluency of the user call, after detecting that the signal quality parameters do not meet the requirements, the terminal generates a voice service downgrading type operation identifier to indicate the terminal to actively release the RRC connection of the first network after entering a call scene to interrupt the first network.

In some embodiments, after registering with the first network, the method further comprises:

and under the condition that the working state is judged without entering the voice service downgrade logic, the terminal resides in the first network, and voice service connection is established with a target terminal corresponding to the voice service request in the first network.

If the terminal does not need to enter the voice service downgrading logic to judge the working state, the network state of the first network can bear the voice service, and the user can indicate that the terminal does not need to carry out downgrading operation, and under the condition, the terminal continuously resides in the first network to carry out voice communication.

In some embodiments, after the terminal resides in the first network and establishes the voice service, the network device end may decide whether the terminal needs to perform network fallback such as switching or redirection according to the network state reported by the terminal, and when a network fallback indication sent by the network device is received, switch to a third network corresponding to the network fallback indication, and establish a voice service connection with a target terminal corresponding to the voice service request in the third network.

Therefore, after the terminal does not actively carry out network switching, the terminal can rely on the network equipment to carry out network fallback, and therefore the terminal can be guaranteed to finish voice communication of a user.

and determining that the function switch judged by the voice service downgrade logic is in an open state.

And if the function switch for the voice service reduced system logic judgment is in a closed state, determining that the voice service reduced system logic judgment working state is not required to be entered.

The state of the function switch may be controlled based on the acquired external information, for example, the terminal may control the switch state thereof according to touch input, voice input, gesture input, or the like of the user, and may also control the switch state according to a signal quality parameter of the first network to which the terminal is currently connected.

The state of the function switch can be regulated and controlled by configuration information in the non-volatile memory NV, can be regulated and controlled by macro definition, and the like, for example, in the initial development stage of the terminal, after a developer configures the terminal to be powered on and connected to the network, the function switch is turned on by default, or after the terminal is powered on and connected to the network, the function switch is turned off by default, and after receiving a turn-on instruction of a user, the function switch is regulated and controlled to be switched to the on state.

For example, in some embodiments, after the terminal is powered on and accesses the network, a network configuration interface is displayed, the function switch in the network configuration interface is not turned on by default, and when a user operation triggering the function switch is detected, the function switch is switched to an on state, where the user operation may be a user inputting a specific piece of voice information, or may be any form of touch operation such as a single click, a double click, a slide, or the like, or may be a key operation such as pressing a volume control key and a power on/off key at the same time.

The voice service status may be a historical status of the voice service carried by the first network within a certain time period, for example, if the terminal receives a voice service request of the first network at 10 o ' clock, the terminal may obtain the status of the voice service carried by the first network within the time period from 10 o ' clock to 11 o ' clock on the previous days.

The voice traffic condition may also be a condition of voice traffic during a period of time up to a current time point after accessing the first network.

Therefore, the terminal can automatically adjust the voice service drop system logic judgment working state according to the acquired voice service condition of the first network, the intelligence of the terminal is improved, the conditions of noise or interruption and the like caused by network drop of a subsequent terminal in the conversation process can be avoided, and the stability and the success rate of the conversation are effectively improved.

In some embodiments, the voice service status includes a service volume of the voice service, and it is determined that the service volume of the voice service supported by the first network is greater than a preset service volume and a voice service downgrade logic judgment working state needs to be entered.

And determining that the voice service downgrade logic judgment working state is not required to be entered when the service volume of the voice service supported by the first network is detected to be less than or equal to the preset service volume.

The traffic volume of the voice service refers to the number of terminals performing voice communication in the first network.

It can be understood that the capability of the first network for bearing the voice service is limited, and if the current voice service volume of the first network is high, conditions such as call drop, call failure and the like may occur in the subsequent process of using the first network to perform the voice call, so in order to improve the stability and the success rate of the call, the terminal may actively enter the voice service downgrading logic judgment working state when the traffic volume of the first network is higher than the preset traffic volume.

In some embodiments, the voice service condition includes a call success rate of the voice service, and it is determined that the call success rate of the voice service supported by the first network is less than a preset success rate, and it is necessary to enter a voice service reduced logic judgment working state.

And determining that the working state does not need to be judged by the voice service downgrading logic when the call success rate of the voice service supported by the first network is greater than or equal to the preset success rate.

The call success rate refers to a percentage of voice services in which there are no call failure events such as dropped call, failed connection, noise occurrence in the call, interruption, and the like in all the voice services initiated on the first network.

It can be understood that, if the call success rate of the voice service of the first network is relatively low, the signal quality representing the first network is relatively poor, so that in order to improve the stability and the success rate of the call, the terminal may enter the voice service downgrading logic to determine the working state when the call success rate of the voice service supported by the first network is greater than or equal to a preset success rate
