It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein may be combined with other embodiments.
The embodiment of the application provides a voice call method, a voice call device and electronic equipment. The main execution body of the voice communication method may be the voice communication device provided in the embodiment of the present application, or an electronic device integrated with the voice communication device, where the voice communication device may be implemented in a hardware or software manner, and the electronic device may be a smart phone, a tablet computer, a palm computer, a notebook computer, or a desktop computer.
Referring to fig. 1, fig. 1 is a first structural schematic diagram of an electronic device according to an embodiment of the present disclosure. The electronic device 100 may include at least a processor 110, a memory 120, a wireless communication module 130, a VOLTE voice call module 140, a Circuit Switched (CS) domain voice call module 150, and the like. The memory 120, the wireless communication module 130, the VOLTE voice call module 140, and the CS domain voice call module 150 are electrically connected to the processor 110, respectively.
The wireless communication module 130 may support an LTE network, a 3G network, a 2G network, and the like. The processor 110 may obtain signal quality information of a serving cell in which the electronic device 100 is located, inter-system neighbor information, and the like through the wireless communication module 130, and select a voice call mode suitable for the electronic device 100 according to the information. For example, when the electronic device 100 communicates LTE signals with a base station, the electronic device 100 may control the VOLTE voice call module 140 to initiate a call primary call. When the electronic device 100 communicates 2G or 3G signals with a base station, the electronic device 100 may control the CS domain voice call module 150 to initiate a call primary call.
Based on the structure of the electronic device 100, the voice call method provided in the embodiment of the present application is described. Referring to fig. 2 and fig. 3, fig. 2 is an application scenario diagram of a voice call method according to an embodiment of the present application, and fig. 3 is a first flowchart of the voice call method according to the embodiment of the present application. The specific flow of the voice call method provided by the embodiment of the application can be as follows:
in 101, signal quality information of an LTE serving cell in which an electronic device is located is acquired.
As shown in fig. 2, each base station has a coverage area, which is a serving cell of the base station transmitting a specific frequency band. For example, if the base station a transmits an LTE signal, the coverage area of the base station a is an LTE serving cell; the base station B transmits a 3G signal, and the coverage area of the base station B is a 3G service cell; when the base station C transmits the 2G signal, the coverage area of the base station C is a 2G service cell; and the base station D transmits the 3G signal, and the coverage area of the base station D is a 3G service cell.
When the electronic device 100 is powered on and the Mobile data switch is turned on, the electronic device 100 first searches all carrier frequency channels within a preset frequency band, and if one or more Public Land Mobile Networks (PLMNs) are searched, and reports all the found Public Land Mobile networks meeting a quality threshold to a Network Attached Storage (NSA) device, the Network Attached Storage device selects a Public Land Mobile Network to be accessed, and selects a serving cell. The electronic device 100 may utilize pre-stored cell list information to make the serving cell selection to obtain the target serving cell. And after the target serving cell is determined, searching the target serving cell in the public land mobile network.
When the signal quality information of the 2G signal, the 3G signal, and the LTE signal all meet the requirements, the electronic device 100 preferentially selects the LTE serving cell according to the above operation, and performs camping on the LTE serving cell. And after the LTE service cell is successfully camped, performing a random access process, wherein the random access process comprises the processes of random access preamble transmission, random access response reception, signaling transmission, contention resolution and the like. Through the random access process, the RRC (Radio Resource Control) completes one transition from the idle state to the connected state, and finally transmits NAS signaling to the MM (Mobile Management) layer to initiate a Service request (Service request) to the Mobility Management node (MME), thereby successfully establishing the RRC connection. After the RRC connection is established, the electronic device 100 may initiate an Attach request (Attach request) to perform network registration, and the server responds to the Attach request to complete registration of the electronic device 100 in the LTE network.
After the electronic device 100 completes the LTE network registration, the electronic device 100 may periodically test the signal quality of the LTE serving cell during the use process. For example, the electronic device 100 periodically sends a test signal to the base station through the wireless communication module 130, the base station receives the test signal and sends a feedback signal to the electronic device 100, and the electronic device 100 can determine the signal quality information of the LTE serving cell where the electronic device 100 is currently located by analyzing the feedback signal. The electronic device 100 may save the signal quality information in the memory 120 for later recall.
In 102, inter-system neighbor cell information of an LTE serving cell in which the electronic device is located is obtained.
The inter-system serving cell is different from other base stations in the signal frequency band transmitted by the serving cell of the base station to which the electronic device 100 is currently connected. For example, when the electronic device 100 currently registers with the LTE serving cell of the a base station, the 3G serving cell of the B base station, the 2G serving cell of the C base station, and the 3G serving cell of the D base station adjacent to the a base station belong to the inter-system neighboring cell of the LTE serving cell of the a base station. Based on this, if the base station a currently registered by the electronic device 100 configures relevant parameters and other information of the base station B, the base station C, and the base station D in advance, at this time, the 3G serving cell of the base station B, the 2G serving cell of the base station C, and the 3G serving cell of the base station D are called as the inter-system neighboring cells of the base station a, and relevant information of the base station B, the base station C, and the base station D is information of the inter-system neighboring cells of the base station a.
A user often moves from the coverage of one base station to the coverage of another base station while using the electronic device 100. When the electronic device 100 moves from base station a to the area covered by base station B, the electronic device 100 needs to complete the handover process.
When the LTE serving cell in which the electronic device 100 is located, for example, the a base station, is configured with inter-system neighbor cell information in advance, the LTE serving cell in which the electronic device 100 is located may actively send the inter-system neighbor cell information to the electronic device 100, and the electronic device 100 may switch to other inter-system neighbor cells according to the inter-system neighbor cell information. Specifically, the base station a may periodically detect a current LTE signal of the electronic device 100, and if the current LTE signal is lower than a certain threshold, the base station a may send inter-system neighbor detection information to a core network server that monitors and controls a plurality of base stations, the core network server may start to arrange service cells of all base stations around the electronic device 100, such as a 3G service cell of the base station B, a 2G service cell of the base station C, a 3G service cell of the base station D, and a 2G service cell of the base station E, periodically detect the current LTE signal of the electronic device 100, and report a detection result to the core network server, the core network server may select a target base station service cell, such as the base station B, as a new base station service cell for handover, and then the core network transmits the handover information to the electronic device 100 through the base station a. After receiving the handover information, the electronic device 100 may cancel the registration information of the LTE serving cell of the old base station a and then register the LTE serving cell with the 3G serving cell of the new base station B. Alternatively, the electronic device 100 may first register with the 3G serving cell of the B base station and then cancel the registration with the LTE serving cell of the old a base station.
When the LTE serving cell, for example, the a base station, in which the electronic device 100 is located does not pre-configure the inter-system neighbor cell information, then, when the current LTE signal quality of the electronic device 100 is lower than a certain threshold, the LTE serving cell, for example, the a base station, in which the electronic device 100 is located does not send inter-system neighbor cell detection information to the core network server, so that the core network server does not perform subsequent detection of the inter-system neighbor cell, and the electronic device 100 cannot be switched to the serving cell with better signal quality, thereby ensuring the call quality of the electronic device 100.
Based on this, in the embodiment of the present application, the electronic device 100 may actively acquire inter-system neighbor cell information of the LTE serving cell in which the electronic device is located. Specifically, the electronic device 100 may send a consultation signal to an LTE serving cell in which the electronic device is located, for example, the a base station, and after receiving the consultation signal, the a base station may send the information about the inter-system neighbor cell to the a base station, and then the a base station selects a voice call mode suitable for the electronic device 100 according to the information about the inter-system neighbor cell and the aforementioned signal quality information. The inter-system neighbor cell information may include information on the number of inter-system neighbor cells, information on a transmission frequency band of the inter-system neighbor cells, information on a coverage area of the inter-system neighbor cells, and the like.
In 103, the electronic device is controlled to trigger a long term evolution voice bearer call or trigger a circuit switched domain call according to the signal quality information and the inter-system neighbor cell information.
After the signal quality information of the LTE serving cell in which the electronic device 100 is located and the inter-system neighbor cell information of the LTE serving cell in which the electronic device 100 is located are obtained, a better voice call mode, for example, a VOLTE voice call or a CS domain voice call, may be selected according to the specific signal quality information and the inter-system neighbor cell information.
It is to be understood that, in the implementation, the present application is not limited by the execution sequence of the described steps, and some steps may be performed in other sequences or simultaneously without conflict.
As can be seen from the above, the voice call method in the embodiment of the present application obtains the signal quality information of the LTE serving cell where the electronic device 100 is located; acquiring inter-system neighbor cell information of an LTE service cell in which the electronic device 100 is located; and controlling the electronic equipment 100 to trigger the long term evolution voice bearer call or trigger the circuit switching domain call according to the signal quality information and the inter-system neighbor cell information. Based on this, the voice call method in the embodiment of the present application may select the voice call mode suitable for the current situation of the electronic device 100 according to actual situations of the signal quality information of the LTE serving cell where the electronic device 100 is located and the inter-system neighbor cell of the LTE serving cell where the electronic device 100 is located, so that the quality of the call may be ensured even in an area where the LTE signal is weakly covered. Meanwhile, according to the voice call method in the embodiment of the present application, when the LTE serving cell where the electronic device 100 is located cannot acquire the inter-system neighbor cell information, the electronic device 100 may still actively acquire the number of inter-system neighbor cells of the serving cell where the electronic device 100 is located, so that the acquisition of the inter-system neighbor cell information is more active, and a phenomenon of network signal failure caused by the fact that the LTE serving cell where the electronic device 100 is located does not acquire the inter-system neighbor cell information can be avoided.
Referring to fig. 4, fig. 4 is an application scenario diagram of a method for triggering a long term evolution voice bearer call by an electronic device according to an embodiment of the present application. As shown in fig. 4, the method for controlling the electronic device 100 to trigger the long term evolution voice bearer call may be: the electronic device 100 establishes a connection with an LTE serving cell, for example, an a-base station, in which the electronic device is located, and establishes communication connections with a network and the internet, in which an opposite terminal is located, through the LTE serving cell. Specifically, a CS circuit domain path and a Packet Switch (PS for short) domain path are respectively established between a network where the electronic device 100 is located and a network where the other terminal is located. Then, the electronic device 100 realizes transmission of voice information with the counterpart terminal through the CS circuit domain, and the electronic device 100 realizes transmission of data information with the counterpart terminal through the PS circuit domain.
The method for controlling the electronic device 100 to trigger the circuit switched domain call may be: controlling the electronic device 100 to trigger a different system network searching instruction; and selecting a target inter-system service cell according to the result of the inter-system network searching instruction, and controlling the electronic device 100 to trigger the circuit switching domain call through the target inter-system service cell.
Specifically, the electronic device 100 may periodically search inter-system serving cells of other base stations around the electronic device 100, for example, a 3G serving cell of the base station B, a 2G serving cell of the base station C, and a 3G serving cell of the base station D, under the condition that the inter-system neighboring cell search is met. And then, selecting a target different system service cell according to the signal quality information of each cell. Then, the electronic device 100 may cancel the registration information of the LTE serving cell of the old base station a and register with the 3G serving cell of the new base station B. Alternatively, the electronic device 100 may first register with the 3G serving cell of the B base station, and then cancel the registration with the LTE serving cell of the old a base station, so as to trigger the CS domain voice call through the target inter-system serving cell.
It can be understood that, in the embodiment of the present application, a 3G serving cell may also be preferentially selected as a target inter-system serving cell to establish a CS circuit domain between the electronic device 100 and the opposite terminal. The method for controlling the electronic device 100 to trigger the cs domain call is not particularly limited in this embodiment.
The step of controlling the electronic device 100 to trigger the long term evolution voice bearer call or the circuit switched domain call according to the signal quality information and the inter-system neighbor cell information includes: judging whether the signal quality information meets the signal quality information required by implementing the long-term evolution voice bearing call; judging whether the number of the inter-system adjacent cells is zero or not; when the signal quality information cannot meet the signal quality information required for implementing the long term evolution voice bearer call and the number of the inter-system neighbor cells is zero, controlling the electronic device 100 to trigger the circuit switched domain call.
When the signal quality information satisfies the signal quality information required for implementing the long term evolution voice bearer call or the number of inter-system neighbor cells is greater than zero, the electronic device 100 is controlled to trigger the long term evolution voice bearer call.
It can be understood that, if the signal quality information cannot satisfy the signal quality information required for implementing the VOLTE voice call and the number of the inter-system neighbor cells is zero, it indicates that the network quality of the current electronic device 100 is not sufficient to support the VOLTE call, and the LTE serving cell in which the electronic device 100 is located is not configured with the corresponding inter-system neighbor cells, so that the LTE serving cell cannot send the information of the inter-system neighbor cells to the electronic device 100, and the electronic device 100 cannot switch to the adaptive inter-system serving cell according to the information of the inter-system neighbor cells. At this time, the control may control triggering the CS domain voice call according to the above-mentioned method to ensure normal call.
If the signal quality information meets the signal quality information required for implementing the VOLTE voice call, the VOLTE voice call is preferably selected at this time, so that the quality of the voice call can be improved. If the number of the inter-system neighbor cells is greater than zero, it indicates that the LTE serving cell where the electronic device 100 is located is configured with corresponding inter-system neighbor cell information, the LTE serving cell sends the inter-system neighbor cell information to the electronic device 100, and the electronic device 100 may select a target inter-system serving cell according to the inter-system neighbor cell information. At this time, the electronic device 100 may trigger the VOLTE voice call to dial the call, and then the electronic device 100 is automatically switched to the target inter-system serving cell, so that the VOLTE voice call and the CS domain voice call may be continuously connected, thereby ensuring the call quality.
Wherein, the step of judging whether the signal quality information meets the signal quality information required by implementing the long-term evolution voice bearing call comprises the following steps: acquiring a cell selection reception level value of a serving cell in which the electronic device 100 is located; when the cell selection receiving level value is less than or equal to the preset receiving level threshold value, the signal quality information can not meet the signal quality information required by implementing the long-term evolution voice bearing call; and when the cell selection receiving level value is larger than the preset receiving level threshold value, the signal quality information can meet the signal quality information required by implementing the long-term evolution voice bearing conversation.
Wherein, the step of judging whether the signal quality information meets the signal quality information required by implementing the long-term evolution voice bearing call further comprises: acquiring a first cell selection reception level value of an LTE serving cell in which the electronic device 100 located at a first position is located; acquiring a second cell selection reception level value of an LTE serving cell in which the electronic device 100 located at the second position is located; judging whether the difference value of the first cell selection receiving level value and the second cell selection receiving level value is within a preset range or not; if the judgment result is yes, the signal quality information can meet the signal quality information required by implementing the long-term evolution voice bearing conversation; if the judgment result is negative, the signal quality information can not meet the signal quality information required by implementing the long-term evolution voice bearing call.
It can be understood that, the above two specific procedures for determining whether the Signal quality information satisfies the Signal quality information required for implementing the long term evolution voice bearer call may be determined by Reference Signal Receiving Power (RSRP for short) in actual use. For example. When the current RSRP value of the electronic device 100 is greater than or equal to the preset threshold, the signal quality information can satisfy the signal quality information required for implementing the long term evolution voice bearer call; when the current RSRP value of the electronic device 100 is less than the preset threshold, the signal quality information may not satisfy the signal quality information required for implementing the long term evolution voice bearer call.
The method according to the previous embodiment is further illustrated in detail by way of example. Referring to fig. 5, fig. 5 is a second flowchart illustrating a voice call method according to an embodiment of the present disclosure.
In 201, a cell selection reception level value of an LTE serving cell in which the electronic device is located is obtained.
The Cell selection receiving level value (Srxlev) is a signal strength measure of the serving Cell. After the electronic device 100 is powered on, the LTE serving cell may be preferentially registered, then the electronic device 100 may send an inquiry signal for inquiring quality information of the signal to the serving cell where the electronic device 100 is located, a base station where the serving cell is located may receive the inquiry signal and feed back the inquiry signal to the electronic device 100 as a feedback signal, and the electronic device 100 may calculate a cell selection reception level value of the serving cell where the electronic device 100 is located according to the feedback signal and a corresponding formula.
The calculation formula of the cell selection reception level value may refer to the calculation formula in the related art, and will not be described herein again.
At 202, determining whether the cell selection reception level value is greater than a preset reception level threshold;
in 203, if the cell selection reception level value is greater than the preset reception level threshold, the control electronic device triggers a long term evolution voice bearer call.
When the cell selection reception level value calculated by the electronic device 100 is greater than the preset reception level threshold, for example, when Srxlev > 10, it indicates that the signal quality of the LTE serving cell registered by the electronic device 100 is better at this time, and the requirement of the VOLTE voice call can be met, and at this time, the electronic device 100 can directly initiate the VOLTE voice call, and a high-definition and high-quality voice call can be implemented.
In 204, if the cell selection reception level value is less than or equal to the preset reception level threshold, acquiring inter-system neighbor cell information of the LTE serving cell where the electronic device is located.
When the cell selection reception level value calculated by the electronic device 100 is less than or equal to the preset reception level threshold value, for example, when Srxlev < 10, it indicates that the signal quality of the LTE serving cell registered by the electronic device 100 is poor at this time, and if a VOLTE voice call is triggered, although the VOLTE voice call may be initiated, the VOLTE voice call quality is poor, and the call may be disconnected or even dropped.
Based on this, when the cell selection reception level value is less than or equal to the preset reception level threshold, the electronic device 100 needs to change to another communication mode to ensure the communication quality. At this time, if the LTE serving cell in which the electronic device 100 is located does not pre-configure the inter-system neighbor cell information, then, under the condition that the cell selection reception level value is less than or equal to the preset reception level threshold, the LTE serving cell in which the electronic device 100 is located, for example, the a base station, may not send the inter-system neighbor cell information to the electronic device 100, and the electronic device 100 may not switch to the serving cell with better signal quality according to the inter-system neighbor cell information, so that the call quality of the electronic device may not be guaranteed.
In this embodiment, the electronic device 100 may actively acquire information of the inter-system neighboring cell. The information of the inter-system neighboring cells may include the number of the inter-system neighboring cells, for example, 3 or 5, and may also include the signal types transmitted by the inter-system neighboring cells, for example, 3G or 2G.
In 205, it is determined whether the number of inter-system neighbor cells is zero;
in 206, if the number of the inter-system neighbor cells is zero, the control electronic device triggers the circuit switched domain call.
In 207, if the number of the inter-system neighbor cells is greater than zero, the electronic device is controlled to trigger a long term evolution voice bearer call.
After obtaining the information of the inter-system neighbor cell, the electronic device 100 may store the information in the electronic device 100 for subsequent call. The electronic device 100 may determine whether the number of the current inter-system neighbor cells is zero according to the inter-system neighbor cell information.
If the number of the inter-system neighbor cells is zero, it indicates that the LTE serving cell where the electronic device 100 is located does not configure inter-system neighbor cell information, and the electronic device 100 needs to search for other serving cells around the electronic device 100 at this time to determine whether other 2G inter-system serving cells and other 3G inter-system serving cells exist around the electronic device. When other 2G and 3G inter-system service cells exist around the electronic device 100, the electronic device 100 may trigger a CS domain voice call, and the electronic device 100 may automatically switch to a Circuit Switched Fallback (CSFB) mode to perform the voice call after initiating the call, and at this time, the electronic device 100 may automatically switch to the 2G or 3G service cell to perform the CS domain call.
If the number of the inter-system neighbor cells is greater than zero, it indicates that the LTE serving cell where the electronic device 100 is located is configured with corresponding inter-system neighbor cell information, the LTE serving cell sends the inter-system neighbor cell information to the electronic device 100, and the electronic device 100 may select a target inter-system serving cell according to the inter-system neighbor cell information. At this time, the electronic device 100 may trigger the VOLTE voice call to dial the call, and then the electronic device 100 is automatically switched to the target inter-system serving cell, so that the VOLTE voice call and the CS domain voice call may be continuously connected, thereby ensuring the call quality.
As can be seen from the above, in the voice call method according to the embodiment of the present application, the signal quality of the serving cell currently connected to the electronic device 100 is determined by the cell selection reception level value, and then whether there are other available 2G inter-system neighboring cells and 3G inter-system neighboring cells in the electronic device 100 is determined by determining the number of the current inter-system neighboring cells of the electronic device 100, so that a better voice call method can be objectively and accurately selected according to the cell selection reception level value and the information of the current inter-system neighboring cell.
The method according to the preceding embodiment will be described in further detail below by way of example. Referring to fig. 6, fig. 6 is a third flowchart illustrating a voice call method according to an embodiment of the present disclosure.
In 301, a first cell selection reception level value of an LTE serving cell in which the electronic device at the first location is located is obtained;
in 302, obtaining a second cell selection reception level value of an LTE serving cell in which the electronic device at the second location is located;
in 303, determining whether a difference between the first cell selection reception level value and the second cell selection reception level value is within a preset range;
in 304, if the determination result is yes, the control electronic device triggers a long term evolution voice bearer call.
In 305, if the determination result is negative, inter-system neighbor cell information of the LTE serving cell where the electronic device is located is obtained.
The base station antenna radiates electromagnetic wave signals to the periphery by taking the antenna iron tower as a center, the signals at the position close to the base station are stronger, and the signals at the position far away from the base station are weaker. In this embodiment, after the electronic device 100 is powered on and connected to the LTE serving cell, the electronic device 100 may periodically obtain a cell selection reception level value of the electronic device 100. Specifically, a first cell selection reception level value may be detected when the electronic device 100 is at a first location, and then a second cell selection reception level value may be detected when the electronic device 100 is at a second location.
If the first cell selection reception level value and the second cell selection reception level value are within the preset range, it indicates that the signal received by the electronic device 100 is substantially unchanged, and the user has a high probability of being in an area where the signal quality of the current LTE serving cell is similar to that of the LTE serving cell and the signal quality of the LTE serving cell is better. Then, at this time, the electronic device 100 may predict that the signal quality of the current serving cell received after the electronic device 100 is sufficient to support the VOLTE call, and at this time, may directly control the electronic device 100 to trigger the CS domain call.
When the first cell selection reception level value and the second cell selection reception level value are out of the preset range, it indicates that the signal received by the electronic device 100 is increasingly poor, and the user probably moves towards an area with poor signal quality of the current serving cell, at this time, the electronic device 100 may predict that the signal quality of the current serving cell received after the electronic device is not enough to support VOLTE call, at this time, the electronic device 100 may be directly controlled to trigger CS domain call, thereby ensuring the call quality requirement.
In 306, judging whether the number of the inter-system adjacent cells is zero or not;
in 307, if the number of the inter-system neighbor cells is zero, the control electronic device triggers the circuit switched domain call.
In 308, if the number of the inter-system neighboring cells is greater than zero, the electronic device is controlled to trigger a long term evolution voice bearer call.
If the number of the inter-system neighbor cells is zero, it indicates that there are no other 2G inter-system neighbor cells or 3G inter-system neighbor cells around the serving cell where the electronic device 100 is located. At this time, the electronic device 100 may trigger a CS domain voice call.
If the number of the inter-system neighbor cells is greater than zero, it indicates that the LTE serving cell where the electronic device 100 is located is configured with corresponding inter-system neighbor cell information. At this time, the electronic device 100 may trigger the VOLTE voice call to dial a call, and then the electronic device 100 automatically switches to the target inter-system neighbor cell, so that uninterrupted connection between the VOLTE voice call and the CS domain voice call may be achieved, thereby ensuring call quality.
It is to be understood that terms such as "first," "second," and the like in the embodiments of the present application are used merely to distinguish similar objects, and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.
As can be seen from the above, in the voice call method according to the embodiment of the present application, whether the electronic device 100 is always in the area with better signal quality is determined by the cell selection reception level values at different positions, so that the current signal quality of the electronic device 100 can be dynamically determined, and in the subsequent step, the voice call mode is determined by the cell selection reception level difference values at different positions and the number of the inter-system neighboring cells, so that the determination is more accurate.
