Although the LTE system is described above as an example, it should be understood by those skilled in the art that the present invention is not limited to LTE systems, but may be applied to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, and future new network systems.

Based on the above mobile terminal hardware structure and the communication network system, various embodiments of the terminal voice calling method are provided.

The invention provides a terminal voice calling method, which is mainly applied to mobile terminal equipment, but is not limited to mobile terminals, and can also be other intelligent terminals, and the terminal voice calling method comprises the following steps:

Referring to fig. 3, the present invention provides a terminal voice call method, in one embodiment of the terminal voice call method, the terminal voice call method includes the steps of:

step S10, when detecting that a 5G network in a first terminal receives an incoming call notification and a signaling corresponding to a second terminal, acquiring the signaling based on the 5G network;

the 5G network is a fifth generation mobile communication network, and in the 5G network and the whole network architecture, the wireless transmission technologies of the 5G terminal and the base station are not substantially different from those of the 4G network, and are implemented by using OFDM (Orthogonal Frequency Division Multiplexing ) technology. Based on OFDM, the control channel adopts Polar coding technology, and the data transmission adopts LDPC (Low Density Parity Check Code ) coding technology.

The current full network networking is as shown in fig. 5: fig. 5 shows the current 2G, 3G, 4G, 5G full network architecture, and network elements such as ng_ RAN, AMF, PGW _ U, PGW _ C, PCRF constitute a 5G network; E_URAN, MME, serving Gateway, PDN GW, PCRF and other network elements form a 4G network, and the upper units form 2G and 3G networks in the figure. Wherein the IMS (IP Multimedia Subsystem, multimedia subsystem) is a multimedia subsystem that implements high definition voice, video. Currently, in the 5G voice scheme, voice service is borne by a 5G or 4G network, and there are various choices of the 5G voice scheme, for example, as shown in fig. 6, when a non-independent networking NSA is performed, a dual link is mainly used to implement 5G and 4G networking, and the 4G network provides voice service, that is, the voice service is only needed to be carried through LTE (VOLTE). In the independent networking SA, the fallback LTE (EPS falllback), i.e. the fallback 4G scheme, may be selected when only LTE provides voice, when the voice call is initiated to be switched to LTE; or when only LTE provides voice, adopting a 4G and 5G dual standby scheme, wherein one network in the terminal is to bear voice service on LTE, and the other network is to bear data service on NR; the method can also be that when NR provides voice service, VONR and switching LTE are synchronously performed, voice is used on NR, and when the NR leaves the coverage, the voice is switched to the VoLTE through a single standby mode; and when the NR provides voice service, the LTE upgrading is accessed to 5GC, and the NR and the eLTE realize unified control.

It can be known from the 5G voice scheme that the 5G independent networking mainly has a single standby mode and a double standby mode, and in the single standby scheme, IMS (multimedia subsystem) voice and CS (3G, 2G circuit domain) voice need to be considered. Therefore, if the terminal needs to initiate a voice call or receive a voice call while the 5G network is in standby, the terminal needs to fall back to the 4G network, and if the IMS function in the terminal is normal, the terminal falls back to the CS domain, and after the call is ended, the terminal needs to be restored to the 5G network again.

In this embodiment, when it is detected that the first terminal waits in the 5G network and receives the incoming call notification sent by the second terminal, the 5G network knows that the first terminal and the second terminal need to answer to the CS domain (Circuit Switched Domain ) so as to meet the normal communication connection of the first terminal and the second terminal, and at this time, the 5G network automatically sends a call signaling to the first terminal system, and after the first terminal answers the call signaling, sends a release signaling again so as to send the cell information of the target cell set in the CS domain to the first terminal system. Wherein the signaling is a signal used to control the circuit.

Step 20, obtaining the cell information of the target cell set in the CS domain of the circuit domain in the signaling, and registering in the CS domain based on the cell information;

the CS domain (Circuit Switched Domain ), which in this embodiment may be a 2G network or a 3G network, and the cell may be the smallest area unit within the mobility management. After detecting that the first terminal system has responded to the signaling sent by the 5G network, the first terminal system also needs to acquire the cell information of the target cell set and the priority cell in the CS domain in the signaling, and search the network according to the cell information to determine the current position of the first terminal, namely, the cell corresponding to the first terminal needs to be searched, and register the first terminal in the CS domain according to the cell. The target cell set may be a cell set within a preset range in the CS domain. The preferred cell may be a cell that the first terminal preferentially searches for.

Step S30, the incoming call notification is acquired based on the CS domain, and the incoming call notification is responded.

When the first terminal has registered the CS domain, it can be considered that the first terminal can establish normal communication connection with the second terminal at this time, and at this time, the first terminal can directly obtain the incoming call notification in the CS domain and respond to the incoming call notification in the first terminal, where the responding mode may be a voice mode or a vibration mode. And after the response is finished, the network of the first terminal is restored to the 5G network again.

In this embodiment, when detecting that a 5G network in a first terminal receives an incoming call notification and signaling corresponding to a second terminal, the signaling is acquired based on the 5G network; acquiring cell information of a target cell set in a CS domain of a circuit domain in the signaling, and registering in the CS domain based on the cell information; and acquiring the incoming call notification based on the CS domain, and responding to the incoming call notification. And when the terminal needs to make an incoming call, the terminal can directly fall back to the CS domain from the 5G network, namely, the call can be realized only by falling back once, and the call can be made only by falling back twice as in the prior art, thereby improving the efficiency of the voice call of the terminal.

Further, on the basis of the first embodiment of the present invention, a second embodiment of the terminal voice call method of the present invention is provided, where the embodiment is a step S30 of the first embodiment of the present invention, and the step of registering in the CS domain based on the cell information is refined, referring to fig. 4, including:

step S31, a position area and a routing area of the first terminal in the CS domain are acquired;

a location area may refer to a set of cells in a mobile communication system, which is an important component of mobile station (or handset) mobility management. The routing area may be a service area of each Location Area (LA) subdivided into several routing areas on the GPRS communication network, each of which contains cells. Wherein one routing area is composed of one to a plurality of cells, one location area is composed of one to a plurality of routing areas, and the location area includes data traffic and voice traffic, and the routing area includes only data traffic. After the cell information of the target cell set and the priority cell is acquired in the CS domain, it is also necessary to determine the location area and the routing area of the first terminal in the CS domain in the target cell set.

Step S32, a first cell matched with the position information of the first terminal is obtained from the cell information, and the position area and the routing area are updated and registered based on the first cell.

After the location area and the routing area of the first terminal in the CS domain are acquired in the CS domain, a first cell with the current location information of the first terminal is determined in the cell information, and the location area and the routing area are updated and registered according to the first cell, so that the accuracy of the location area and the routing area corresponding to the first terminal in the CS domain is ensured. Wherein the first cell may be a cell having current location information of the first terminal.

In this embodiment, the location area and the routing area of the first terminal in the CS domain are updated and registered according to the first cell having the current location information of the first terminal, so that accuracy of the location area and the routing area corresponding to the first terminal in the CS domain is ensured.

Specifically, after the step of acquiring the first cell having the first terminal position information in the cell information, the method includes:

step S33, judging whether the first cell is converted into a second cell in a preset time period;

after the first cell with the second terminal location information is acquired, it is further required to determine whether the first cell with the second terminal location information changes within a preset period of time, that is, whether the location where the second terminal is located changes. And when the first cell is not changed, the subsequent incoming call operation is continuously executed, but when the first cell is changed, the first cell is changed into the second cell, whether the first terminal is still in the range of the target cell set is needed to be judged, and different operations are executed according to the basic judgment result.

And step S34, if the first cell is not converted into a second cell in a preset time period, updating and registering the location area and the routing area based on the first cell.

When the first cell is judged to be not converted into the second cell in the preset time period, the first terminal can be considered to be not moved in the preset time period, and the position area and the routing area of the first terminal in the CS domain can be updated and registered directly according to the first cell, so that the accuracy of the position area and the routing area of the first terminal in the CS domain is ensured.

In this embodiment, whether the position of the first mobile terminal moves is determined by whether the terrible first cell is converted into the second cell, and when it is determined that the first cell is not converted into the second cell, update registration can be directly performed on the position area and the routing area according to the first cell, so that accuracy of update registration of the position area and the routing area is ensured.

Specifically, after the step of determining whether the first cell is switched to the second cell in the preset time period, the method includes:

step S35, if the first cell is converted into a second cell in a preset time period, judging whether the target cell set comprises the second cell;

when the first cell is judged to be converted into the second cell in the preset time period, the position of the second terminal can be considered to be changed, the position of the first terminal after the movement and the corresponding second cell are required to be acquired, whether the second cell is in the range of the target cell set or not is required to be judged, namely whether the target cell set comprises the second cell or not is determined, and whether the position of the first terminal after the movement can normally establish communication connection with the second terminal or not is determined according to the judging result. The second cell may be a cell containing the location information after the first terminal moves.

Step S36, if the target cell set includes a second cell, updating and registering the location area and the routing area based on the second cell.

When the target cell set is judged to include the second cell, the location area and the route of the first terminal in the CS domain can be updated and registered directly based on the second cell, so that the first terminal and the second terminal can establish normal communication connection.

When the target cell set is judged to not include the second cell, the environment where the first terminal is located can be considered to be incapable of receiving the network signal and establishing communication connection with the second line terminal, so that the CS domain corresponding to the first terminal can be restored to the 5G network.

In this embodiment, when the first cell is detected to be converted into the second cell, it is further required to determine whether the target cell set includes the second cell, and determine whether the position of the first terminal after moving can normally establish communication connection with the second terminal based on the determination result, so that normal performance of voice call between the first terminal and the second terminal is ensured.

Specifically, the step of updating and registering the location area and the routing area based on the first cell includes:

step S311, obtaining the position information of the first terminal in the first cell, and updating and registering the position area based on the position information;

and acquiring the position information of the first terminal in the first cell, and updating and registering the position area of the first terminal in the CS domain according to the position information of the first terminal so as to ensure the accuracy of the position area in the CS domain.

Step S312, acquiring a preset data card in the first terminal, and updating and registering the routing area based on the preset data card and the location information.

The preset data card may be a data card that is set by a user in advance, and when only one data card exists in the first terminal, the routing area in the CS domain may be updated and registered directly according to the data card and the location information, but when there are multiple data cards in the first terminal, the preset data card that needs to establish communication connection with the second terminal needs to be determined in the data cards, and then the routing area is updated and registered according to the preset data card and the location information of the first terminal.

In this embodiment, the location information is updated according to the location information in the first cell, and the routing area is updated through the data card and the location information in the first terminal, so that the accuracy of the location area and the routing area is ensured.

Further, on the basis of any one of the first to second embodiments of the present invention, a third embodiment of a voice call method for a terminal of the present invention is provided, where the step S10 of the first embodiment of the present invention is a step of acquiring, when detecting that a 5G network in a first terminal receives an incoming call notification and signaling sent by a second terminal, the signaling based on the 5G network, and includes:

step A10, when detecting that a 5G network in a first terminal receives an incoming call notification and signaling corresponding to a second terminal, judging whether the first terminal supports a multimedia subsystem IMS function;

when detecting that the 5G network in the first terminal receives the incoming call notification and signaling corresponding to the second terminal, it is necessary to determine whether the first terminal supports the multimedia subsystem IMS function, and execute different operations based on the determination result. The IMS is a multimedia subsystem for realizing high-definition voice and video.

And step A11, if the first terminal supports the IMS function, acquiring the signaling based on the 5G network.

When the first terminal is judged to support the IMS function, signaling can be acquired based on the 5G network, so that the 5G network can be directly dropped to the CS domain. But when the first terminal is judged to not support the IMS, the 5G network in the first terminal can fall back to the CS domain directly, namely, the signaling is acquired in the CS domain.

In this embodiment, by determining whether the first terminal supports the IMS function and determining whether the first terminal is capable of performing a voice call through the 5G network based on the determination result, the use experience of the user is improved.

Further, after the step of responding in the first terminal based on the incoming call notification, it includes:

and step S50, if the incoming call notification is completed, the CS domain is restored to the 5G network.

And when the communication connection between the first terminal and the second terminal is detected to be closed, namely the response of the first terminal is ended, the CS domain corresponding to the first terminal is directly restored to the 5G network at the moment, so that the first terminal is kept to be continuously standby in the 5G network.

In this embodiment, after detecting that the incoming call has been responded, the CS domain may be directly restored to the 5G network, so that the first terminal is prevented from being standby in the CS domain all the time, and the use experience of the user is improved.

Further, on the basis of any one of the first to third embodiments of the present invention, a fourth embodiment of the terminal voice call method of the present invention is provided, the terminal voice call method further comprising:

step S70, judging whether the first terminal supports the 5G network and IMS function when detecting the voice call instruction;

when the voice call instruction input by the user is detected in the first terminal, whether the first terminal supports the 5G network and the IMS function is automatically detected, and when the first terminal supports the 5G network and the IMS function, the 5G network can be directly dropped back to the CS domain, so that the first terminal can quickly call to the terminal corresponding to the voice call instruction.

Step S80, if the first terminal supports the 5G network and IMS function, the cell information of the target cell set in the CS domain is obtained, and registration is carried out in the CS domain based on the cell information.

When the first terminal is detected to support the 5G network and the IMS function, the cell information of the target cell set is required to be acquired in the CS domain through the 5G network, the cell position corresponding to the current moment of the first terminal is acquired in the cell information, registration is carried out in the CS domain according to the cell position, and then the voice call is sent to the network of the terminal corresponding to the voice call instruction.

In this embodiment, when the first terminal sends a voice call to other terminals, the 5G network falls back to the CS domain directly, that is, the call can be realized only by falling back once, and the call can be performed only by falling back twice unlike the prior art, thereby improving the efficiency of the voice call of the terminal.
