Fig. 1 is a schematic diagram of a communication system architecture provided in the present application.

Referring to fig. 1, the communication system includes a calling terminal 100, a calling side LTE base station 110, a calling side NR base station 120, a core network 130, a called terminal 140, a called side LTE base station 150, and a called side NR base station 160. The calling side LTE base station 110 and the called side LTE base station 150 may provide 4G network radio access for one or more calling terminals 100 and called terminals 140 within a coverage area, so that the user terminals can communicate with each other; the caller-side NR base station 120 and the callee-side NR base station 160 may provide 5G network radio access for one or more of the caller terminals 100 and callee terminals 140 within a coverage area to enable intercommunication between user terminals. When the terminal performs voice call, the voice call of VoNR can be performed through an independent networking SA mode, and the voice call of VoLTE can be performed through a non-independent networking NSA mode, wherein the SA mode refers to an independent networking mode, is a brand new 5G network mode and comprises brand new 5GNR base stations and 5G core networks. NSA mode is a dual connectivity network mode of a 4G radio access network and 5GNR, i.e. a 4G LTE and 5GNR new radio dual connectivity architecture of a non-independent networking: in NSA mode, the UE establishes a connection with the 4G core network while using radio resources of at least two different base stations (a 4G base station being the master station and a 5GNR base station being the slave station), transmitting signaling by means of the 4G core network, the 4G base station or the 5GNR base station transmitting data traffic. The main difference between SA mode and NSA mode is the difference between the core network accessed: in NSA mode, the 5GNR base station is accessed to a 4G core network, and transmits signaling through the 4G core network, and the 4G base station or the 5GNR base station transmits data service; in NSA mode of the terminal, the operator may share a 4G core network with both 4G and 5G. In SA mode, the 5GNR base station is directly connected to the 5G core network, and transmits signaling through the 5G core network, and the 5GNR base station transmits data service. NSA mode is a transitional networking mode in the early stages of 5G construction.

The base station can also be called a base station system and consists of a plurality of independent base station devices, and a complete base station device also comprises power supply, storage battery, air conditioner, security monitoring and other matched devices. The calling side LTE base station 110 and the called side LTE base station 150 mainly include three parts, namely, a BBU (buildingbasebaseband Unit), an RRU (radio remote Unit), and a radio frequency antenna, the BBU is mainly responsible for signal modulation, the RRU is mainly responsible for radio frequency processing, and the antenna is mainly responsible for conversion between a cable uplink traveling wave and a space wave in the air. Compared with the LTE base station, the caller-side NR base station 120 and the callee-side NR base station 160 combine the RRU and the radio frequency antenna before the LTE base station into an AAU (active antenna unit), and are connected to the BBU through an optical fiber. Base stations can be classified into macro base stations (MacroSite), micro base stations (MicroSite), pico base stations (PicoSite), femto base stations (femto site) according to their station type size and power: the single carrier wave transmitting power of the macro base station is more than 10W, and the coverage radius is more than 200 m; the single carrier wave transmitting power of the micro base station is 500mW to 10W, and the coverage radius is 50 meters to 200 meters; the single carrier wave transmitting power of the pico base station is between 100mW and 500mW, and the coverage radius is between 20 meters and 50 meters; the single carrier wave transmitting power of the femto base station is below 100mW, and the coverage radius is between 10 meters and 20 meters.

In the following method embodiments, for convenience of explanation, only the execution subject of each step is described as a terminal.

The voice call method provided in the embodiment of the present application will be described in detail with reference to fig. 2 to 3.

Referring to fig. 2, a flowchart of a voice call method is provided in an embodiment of the present application. The present embodiment is illustrated by applying a voice call method to a terminal, and the voice call method may include the steps of:

s201, a first voice call request is transmitted based on SA mode.

The SA mode is an independent networking mode, is a set of brand-new 5G network mode, and comprises brand-new 5GNR base stations and 5G core networks. The main difference between SA mode and NSA mode is the difference between the core network accessed: in NSA mode, the 5GNR base station is connected with a 4G core network, and transmits signaling through the 4G core network, and the 5GNR base station transmits data service; in NSA mode of the terminal, the operator may share a 4G core network with both 4G and 5G. In SA mode, the 5GNR base station is directly connected to the 5G core network, and transmits signaling through the 5G core network, and the 5GNR base station transmits data service. NSA mode is a transitional networking mode in the early stages of 5G construction. The first voice call refers to a terminal capable of transmitting a VoNR voice call service carried on a 5G NR base station in SA mode.

Generally, when determining that the current networking mode of the terminal is the SA mode, the terminal will send a VoNR call request to obtain VoNR voice communication when receiving a voice call instruction. There are various ways to determine the current networking mode of the terminal:

optionally, the networking mode of the called terminal is acquired through the calling terminal, when the networking mode of the called terminal is SA mode, the current networking mode of the calling terminal is set as SA mode, and the current networking mode of the calling terminal at the moment is SA mode; when the networking mode of the called terminal is NSA mode, the current networking mode of the calling terminal is set to be NSA mode, and at the moment, the current networking mode of the calling terminal is NSA mode.

Optionally, acquiring a networking mode of the called terminal through the calling terminal, when the networking mode of the called terminal is an SA mode, switching the current networking mode of the calling terminal into the SA mode, judging whether the network signal quality in the current networking mode of the calling terminal is the SA mode meets the preset signal quality condition, and when the network signal quality in the current networking mode of the calling terminal is the SA mode meets the preset signal quality condition, setting the current networking mode of the calling terminal as the SA mode, wherein the current networking mode of the calling terminal is set as the SA mode; when the network signal quality in the SA mode is not satisfied, the current networking mode of the calling terminal is set to be an NSA mode, and the current networking mode of the calling terminal is the NSA mode.

S202, when the first voice call request call failure is determined, the recall operation is executed based on the SA mode.

The re-calling operation refers to a voice re-calling request of preset times sent by the terminal when the first voice call request fails to call.

Generally, by acquiring the sending time of the first voice call request, judging whether a call success response corresponding to the first voice call request is received within a preset time period, and if the terminal receives the call success response corresponding to the first voice call request within the preset time period, determining that the call of the first voice call request is successful; if the terminal does not receive the call success response corresponding to the first voice call request within the preset duration, determining that the first voice call request fails to call. When determining that the first voice call request fails, the terminal periodically transmits a voice re-call request according to a preset time interval, and records the number of times of the voice re-call request transmitted by the terminal. And when the first voice call request fails, the terminal sends a re-call request according to a preset time interval, so that the success rate of the voice call of the terminal in the SA mode is improved.

And S203, switching the SA mode to the NSA mode when the re-calling operation call failure is determined.

The dual-connectivity network mode of the NSA mode 4G radio access network and the 5GNR is that of a 4GLTE and 5GNR new radio dual-connectivity architecture of the non-independent networking: in NSA mode, the UE establishes a connection with the 4G core network while using radio resources of at least two different base stations (a 4G base station being the master station and a 5GNR base station being the slave station), transmitting signaling by means of the 4G core network, the 4G base station or the 5GNR base station transmitting data traffic.

Generally, when determining that the first voice call request fails, the terminal periodically sends a voice re-calling request according to a preset time interval, records the number of times of calling the voice re-calling request sent by the terminal, and when the voice re-calling request fails, judges whether the number of times of calling the re-calling reaches the preset number of times, if so, determines that the voice re-calling request sent by the terminal fails; if the number of times does not reach the preset number, continuing to send a new voice re-calling request, and judging whether the new voice re-calling request is successful.

And S204, sending a second voice call request based on the NSA mode.

The second voice call request is a distinction between the first voice call request and the second voice call request, and refers to a more mature and stable VoLTE voice call service that can be sent by the terminal in NSA mode.

In general, when a call fails in a recall operation performed by the terminal based on the SA mode, the terminal switches the current networking mode to the NSA mode, and transmits a second voice call request using the NSA mode.

The terminal sends the second voice call request through NSA mode by:

judging whether the network signal quality of a 5G serving cell of the terminal in an SA mode meets a preset 5G signal quality condition, and if so, taking the 5G serving cell in the SA mode as the 5G serving cell of the terminal in an NSA mode; if not, searching one or more 5G adjacent cells around the 5G service cell, and selecting a target 5G cell from the searched one or more 5G adjacent cells as the current 5G service cell of the terminal in NSA mode, wherein the target 5G cell needs to support NSA mode and meets the preset 5G signal quality condition. After determining the 5G serving cell in NSA mode, searching one or more 4G cells, and selecting a target 4G cell from the one or more searched 4G cells as the 4G serving cell of the terminal in NSA mode, wherein the target 4G cell supports the NSA mode matched with the current 5G serving cell and meets the preset 4G signal quality condition. The terminal sends a second voice call request through an NSA mode composed of the 5G service cell and the 4G service cell.

As can be seen from the foregoing, in the call method provided by the present solution, the terminal sends the first voice call request based on the SA mode, when determining that the first voice call request fails, the terminal performs the recall operation based on the SA mode, when determining that the recall operation fails, the terminal switches the SA mode to the NSA mode, and sends the second voice call request based on the NSA mode. Therefore, the success rate of the 5GVOLTE voice call of the terminal in the SA mode is improved, the robustness of the terminal for sending the voice call is enhanced by the terminal in a mode of switching the SA mode to the NSA mode for sending the VoLTE voice call, and the communication experience of a user for sending the voice call under the 5G network service by using the terminal is improved.

Referring to fig. 3, another flow chart of a voice call method is provided in an embodiment of the present application. The present embodiment is exemplified by a voice call method applied to a terminal. The voice call method may include the steps of:

s301, obtaining the networking mode of the called terminal.

The called terminal is used for sending a voice call request compared with the calling terminal, and the called terminal is used for receiving the voice call request sent by the calling terminal. The networking mode is a 5G networking mode supporting a 5G network service terminal, and the current 5G networking mode comprises two modes: NSA mode and SA mode.

Generally, before the calling terminal sends the first voice call request, the networking mode of the called terminal needs to be acquired, and the current networking mode of the calling terminal is determined according to the networking mode of the called terminal, so that the networking mode of the calling terminal is consistent with the networking mode of the called terminal, and the call success rate of the calling terminal for sending the first voice call is improved.

S302, when the networking mode is the NSA mode, selecting the NSA mode as the current networking mode.

Generally, when the network mode of the called terminal is acquired as the NSA mode, the NSA mode is used as the current network mode, so that a 5G cell and a 4G cell supporting the NSA mode need to be searched as current serving cells, and the 5G cell and the 4G cell serving as the current serving cells need to respectively meet preset 5G signal quality conditions and 4G signal quality conditions so as to ensure that the terminal has a good network state when sending a voice call request.

S303, when the networking mode is SA mode, the SA mode is selected as the current networking mode, and the network signal quality in the SA mode of the current networking mode meets a first preset signal quality condition.

The network signal quality is a factor affecting network transmission performance, the network signal quality is affected by channel capacity, channel bandwidth, signal-to-noise ratio, bit error rate, etc., and the first preset signal quality condition refers to a signal quality condition that needs to be met by a current 5G serving cell of the terminal in SA mode, and is used for measuring stability performance of voice data transmission of the 5G serving cell.

Generally, when the network mode of the called terminal is the SA mode, the SA mode is taken as the current network mode, and meanwhile, whether the network signal quality in the current network mode of the terminal is the SA mode meets the first preset signal quality condition is required to be judged, if so, the current network mode is still the SA mode; if not, switching the 5G service cell in the current networking mode to the 5G cell with the network signal quality meeting the first preset signal quality condition, or switching the current networking mode to the NSA mode.

S304, a first voice call request is initiated based on the SA mode.

The SA mode is an independent networking mode, is a set of brand-new 5G network mode, and comprises brand-new 5GNR base stations and 5G core networks. The main difference between SA mode and NSA mode is the difference between the core network accessed: in NSA mode, the 5GNR base station is connected with a 4G core network, and transmits signaling through the 4G core network, and the 5GNR base station transmits data service; in NSA mode of the terminal, the operator may share a 4G core network with both 4G and 5G. In SA mode, the 5GNR base station is directly connected to the 5G core network, and transmits signaling through the 5G core network, and the 5GNR base station transmits data service. NSA mode is a transitional networking mode in the early stages of 5G construction. The first voice call refers to a terminal capable of transmitting a VoNR call service carried on a 5G NR base station in SA mode.

Generally, when determining that the current networking mode of the terminal is the SA mode, the terminal will send a VoNR call request to obtain VoNR voice communication when receiving a voice call instruction.

Illustrating: referring to the schematic diagram of the terminal display interface in fig. 4, when the terminal is in SA mode, the user sends a first voice call request by using the terminal, a call interface 401 is displayed on the display interface of the terminal, and a VoNR voice call identifier 402 in SA mode is displayed on the call interface 401.

S305, a sending time of the first voice call request is acquired.

The sending time refers to the time when the first voice call request is sent by the terminal, and the time when the first voice call request is sent is recorded so as to record the duration before the call success response corresponding to the first voice call request is received, and further whether the first voice call request is successful or not is judged according to the duration.

Generally, when the terminal sends the first voice call request, the terminal will start a timer at the same time, start recording the duration of the first voice call request for call waiting, and record the sending time of the first voice call request.

S306, based on the sending moment, if a call success response corresponding to the first voice call request is not received within a preset time, determining that the first voice call request fails.

The preset duration refers to a preset waiting time length of the voice call, and is used for measuring whether the voice call is successful or not.

Generally, the sending time of the first voice call request is obtained, the time period from sending the first voice call request to receiving the call success response corresponding to the first voice call request is recorded, and when the time period is greater than the preset time period, the call failure of the first voice call request can be determined.

S307, the re-calling request is sent periodically according to the preset time interval.

The preset time interval is used for indicating a time period for the terminal to send a re-call request, wherein the re-call request is a voice call request compared with the first voice call request when the terminal is in an SA mode.

Generally, the terminal will periodically send a plurality of recall requests according to a preset time interval until a call success response corresponding to the recall request can be received in the preset time interval.

S308, recording the calling times of the re-calling request.

S309, when the number of calls reaches the preset number, determining that the recall request has a recall failure.

The preset times are the times of periodically sending the re-calling request by the terminal, and are the basis for judging whether the terminal finishes periodically sending the re-calling request.

Generally, after the terminal periodically sends the re-calling request, if the number of calls of the re-calling request reaches the preset number, the terminal will end to periodically send the re-calling request, namely, determine that the re-calling request of the terminal fails to re-call, and display the prompt information of voice call failure on the display unit of the terminal; if the number of calls of the re-calling request does not reach the preset number, the terminal will still periodically send the re-calling request until receiving a call success response corresponding to the re-calling request, stopping sending the re-calling request, namely determining that the re-calling request of the terminal is re-called successfully.

Illustrating: referring to the schematic diagrams of the terminal display interfaces in fig. 4 and fig. 5, after the terminal initiates the first voice call request, the call interface 501 is displayed on the display interface of the terminal, and when the terminal does not receive a call success response corresponding to the first voice call request within a preset duration, the terminal will periodically send a voice recall request, for example: the time interval for the terminal to send the voice re-calling request is 6S, the preset calling times are 4 times, and when the first voice calling request fails to call, the terminal sends a re-calling request every 6S; if the terminal receives a call success response corresponding to the re-call request in the time interval 6S for sending the re-call request, the call success of the re-call request is indicated, namely, the call success of the VoNR voice call request sent by the terminal in the SA mode is indicated; if the call success response corresponding to the recall request is not received when the recall request sent by the terminal arrives for 4 times, the terminal indicates that the call of the VoNR voice call request sent by the terminal in the SA mode fails, a prompt interface 501 is displayed on a display interface of the terminal, and the prompt interface 501 is automatically closed after a preset time of 3S.

S310, switching the SA mode to NSA mode.

Generally, after the terminal fails to send the first voice call request call in the SA mode, the terminal starts to send a recall request, and if it is determined that the recall request fails to recall, a new voice call can be sent in the NSA mode by switching the SA mode to the NSA mode, so as to enhance the robustness of the voice call under the 5G network service.

And S311, searching one or more 5G adjacent cells around the 5G serving cell when the 5G serving cell is determined not to meet the third preset signal quality condition.

The 5G service cell refers to a region where the terminal can currently obtain 5G network service, is a cell divided from the whole 5G communication service region, is provided with a 5GNR base station, is responsible for establishing wireless connection with the terminal in the cell, and supports the 5G terminal to perform 5G communication in any cell in the 5G communication service region. The 5G neighbor cell refers to a 5G cell adjacent to a current 5G serving cell in cellular communication, and is a target cell that a terminal can select when switching the current serving cell. The signal quality is a factor affecting the network transmission performance, the signal quality is affected by channel capacity, channel bandwidth, signal-to-noise ratio, bit error rate, etc., and the third preset signal quality condition refers to a signal quality condition that needs to be met by the 5G serving cell, and is used for measuring the stability performance of the data transmission of the 5G cell.

Generally, after the current networking mode of the terminal is switched to the NSA mode, whether the 5G serving cell of the terminal meets a third preset signal quality condition needs to be judged, and if so, the 5G serving cell can be directly used as the 5G serving cell in the NSA mode; if not, one or more 5G neighbor cells around the 5G serving cell need to be searched to find a 5G cell satisfying a third preset signal quality condition as a 5G serving cell.

And S312, selecting a target 5G cell from the one or more 5G adjacent cells as a current 5G serving cell.

The target 5G cell is a 5G cell supporting NSA mode and satisfying a third preset signal quality condition.

Generally, after searching one or more 5G neighbor cells, it is necessary to determine a 5G cell set supporting the NSA mode from the one or more 5G neighbor cells, and further determine, from the 5G cell set, a 5G cell satisfying the third preset signal quality condition as a current 5G serving cell of the terminal in the NSA mode.

And S313, searching one or more 4G cells.

And S314, selecting a target 4G cell from one or more 4G cells as a 4G serving cell.

The target 4G cell is a 4G cell supporting an NSA mode matched with a current 5G service cell and meeting a second preset signal quality condition, the 4G service cell is a region where a terminal can currently obtain 4G network service, the region is a cell divided from the whole 4G communication service region, a 4G base station is arranged in the cell and is responsible for establishing wireless connection with the terminal in the cell, and the 4G terminal is supported to perform 4G communication in any cell in the 4G communication service region. The signal quality is a factor affecting the network transmission performance, the signal quality is affected by channel capacity, channel bandwidth, signal-to-noise ratio, bit error rate, etc., and the second preset signal quality condition is a signal quality condition that needs to be met by the 4G cell, and is used for measuring the stability performance of the data transmission of the 4G cell.

S315, a second voice call request is sent through NSA mode.

The second voice call request is distinguished from the first voice call request, which means that the terminal can send the VoLTE voice call service in NSA mode.

In general, when a call fails in a recall operation performed by a terminal based on an SA mode, the terminal switches a current networking mode to an NSA mode and transmits a second voice call request according to a 5G serving cell and a 4G serving cell supporting the NSA mode.

Illustrating: referring to the schematic diagram of the terminal display interface in fig. 8, after the terminal initiates the first VoLTE call request, the terminal displays a call interface 801 on the display interface, and after detecting that the user clicks the virtual key 802 for ending the call on the call interface 801 within a preset duration, it can determine that the first VoLTE call request fails to call.

Illustrating: referring to the schematic diagram of the terminal display interface in fig. 6, after the current networking mode of the terminal is switched from the SA mode to the NSA mode, the user sends a second voice call request by using the terminal in the NSA mode, at this time, the display interface of the terminal displays a call interface 601, and the VoLTE voice call identifier 602 in the NSA mode is displayed on the call interface 601.

According to the voice call method provided by the scheme, the terminal acquires the networking mode of the called terminal, when the networking mode is the NSA mode, the NSA mode is selected as the current networking mode, when the networking mode is the SA mode, the SA mode is selected as the current networking mode, the network signal quality in the current networking mode is the SA mode and meets the first preset signal quality condition, a first voice call request is initiated based on the SA mode, the sending moment of the first voice call request is acquired, based on the sending moment, if a call success response corresponding to the first voice call request is not received within a preset time period, the first voice call request call failure is determined, the recall request call number is recorded periodically according to a preset time interval, when the call number reaches the preset number, the recall request recall failure is determined, the SA mode is switched to the NSA mode, one or more 5G adjacent cells around the 5G service cell are searched when the 5G service cell is determined not to meet the third preset signal quality condition, one or more 5G adjacent cells are selected as the first 5G service cell or the second 5G service cell, the 5G adjacent cells are selected as the target cell or the target cell 4G service cells, and the target cell 4G service cells are searched for the multiple 4G service cells, and the target cells are selected as the 4G service cells. In this way, after the terminal fails to send the first voice call request call in the SA mode, the terminal sends the voice call request periodically for multiple times to increase the call success rate of sending the voice call request for VoNR under the 5G network service, if the terminal still fails to send the voice call request for VoNR in the SA mode, the terminal switches the SA mode to the NSA mode and sends the voice call for VoLTE in the NSA mode, so as to further increase the robustness of sending the voice call request for voice call under the 5G network service.
