Based on the hardware structure of the mobile terminal 100 and the communication network system, various embodiments of the method of the present invention are provided.

First, the present invention provides a mobile terminal, which includes a memory, a processor, and a call control program 400 stored in the memory and operable on the processor. In order to implement the call control method of the present invention, the mobile terminal of the present invention has dual antennas, which are respectively marked as a first antenna and a second antenna, and under normal conditions, one of the antennas is used for network communication while the other antenna is in a sleep mode.

Fig. 3 is a functional block diagram of a call control procedure 400 according to a first embodiment of the present invention. In this embodiment, the call control program 400 may be divided into one or more modules, and the one or more modules are stored in the memory 109 of the mobile terminal 100 and executed by one or more processors (in this embodiment, the controller 110) to implement the present invention. For example, in fig. 3, the call control procedure 400 can be divided into a detection module 401, a standby antenna control module 402, and a channel switching module 403. The module referred to in the present invention refers to a series of computer program instruction segments capable of performing specific functions, and is more suitable than a computer program for describing the execution process of software in the mobile terminal 100. The detailed description of the functions of the

functional modules

401 and 403 will be described below. Wherein:

the detecting module 401 is configured to detect whether a network silence problem occurs in a current call during a call.

The network silence problem refers to silence caused by network problems, and the reasons for generating the silence problem can be various in the conversation process, but the invention only optimizes the silence caused by the network problems. Specifically, in this embodiment, the step of detecting whether the current call has the network silence problem includes: (1) judging whether the voice data packets received by the mobile terminal are the same data packets or the same data packets with the same cycle; (2) if the judgment result is yes, the network silence problem of the current call is judged, otherwise, the silence problem does not occur or the silence problem occurs but is not caused by the network problem, and the two situations are not optimized by the method and the device. When the mobile terminal carries out communication, the mobile terminal receives a voice data packet sent by a communication opposite side in real time, under the condition of normal communication, the content of the voice data packet is not the same, and when the network silence problem occurs, the received voice data packet is a data packet which is the same in duration or a data packet which is the same in periodic cycle, so that whether the network silence problem occurs at present can be judged by detecting the content of the voice data packet. In addition, it should be noted that the detection module 401 is executed only when the mobile terminal is in a call state.

The standby antenna control module 402 is configured to start a standby antenna of the mobile terminal to search a target channel through the standby antenna when the detection result of the detection module 401 is that a network silence problem occurs in a current call.

In the present invention, the mobile terminal has dual antennas, which are respectively referred to as a first antenna and a second antenna, and usually one of the dual antennas is used as a default antenna for communication, while the other dual antenna is used as a standby antenna, and the standby antenna is in a sleep mode when not in use. Such as: the first antenna is set as a default antenna, the second antenna is set as a standby antenna, when the mobile terminal carries out communication, the first antenna is used for receiving a voice data packet sent by a communication counterpart, the second antenna is in a sleep mode, namely, in an off state, at the moment, when the mobile terminal detects a network silence problem, the standby antenna (namely, the second antenna) is started, the standby antenna enters an operating mode from the sleep mode, the standby antenna can search a channel with good network quality in the operating mode, and the searched channel with good network quality is used as a target channel.

The channel switching module 403 is configured to send a channel switching instruction to the network end of the current call, and switch the current antenna used in the current call to the target channel, so that the current antenna and the network end perform a call through the target channel.

When the mobile terminal carries out a call, the mobile terminal establishes communication connection with a call counterpart, at the moment, the mobile terminal receives a voice data packet from a network terminal through a default antenna, and a path of the default antenna and the network terminal for transmitting the voice data packet is marked as an initial channel. When the initial channel has a problem and causes a network silence problem in a call process, the mobile terminal starts a standby antenna to search a target channel, and then sends a channel switching instruction to a network end of the current call through the standby antenna, and then the mobile terminal switches a current antenna (namely a default antenna) used by the current call to the target channel, and the network end also switches to the target channel after receiving the channel switching instruction, and at the moment, the network end and the mobile terminal carry out the call through the target channel. Referring to fig. 7, fig. 7 is a schematic diagram of an embodiment of a method for performing call control when a mobile terminal a and a mobile terminal B are in a call, wherein two dotted line boxes before and after an arrow respectively represent communication between the mobile terminal a and the mobile terminal B before and after channel switching, and fig. 7 illustrates that the mobile terminal a detects a network silence problem, as shown in fig. 7, the mobile terminal a includes a default antenna and a standby antenna, during the call between the mobile terminal a and the mobile terminal B, the default antenna communicates with the network, receives a voice data packet from the network or sends a voice data packet to the network, at this time, a transmission channel between the default antenna and the network is marked as an initial channel, and then when the mobile terminal a detects the network silence problem, the standby antenna searches for a new channel, marks the searched channel as a target channel, and then the mobile terminal sends a channel switching instruction to the network through the standby antenna, and the default antenna is switched to the target channel, the network end can be switched to the target channel after receiving the channel switching instruction, and then the network end and the default antenna communicate through the target channel.

Through the

module

401 and 403, the call control program of the present invention detects whether a network silence problem occurs in a current call during a call, if the network silence problem occurs, starts a standby antenna of the mobile terminal to search a target channel through the standby antenna, and sends a channel switching instruction to a network end of the current call after the target channel is searched, and switches a current antenna used in the current call to the target channel, so that the current antenna and the network end communicate through the target channel, thereby realizing that when the current channel has a problem, the antenna is switched to another channel for communication, solving the silence problem caused by the network problem, and improving user experience.

Further, based on the above-described first embodiment of the call control program 400 of the present invention, a second embodiment of the call control program 400 of the present invention is proposed. Referring to fig. 4, fig. 4 is a functional block diagram illustrating a call control procedure 400 according to a second embodiment of the present invention, wherein, compared with the first embodiment, the call control procedure 400 further includes a call quality determination module 404. In this embodiment, each functional module is described as follows:

the call quality determining module 404 is configured to determine whether the call quality of the current call is qualified when the detection result of the detecting module 401 is negative, that is, the network silence problem is not detected, and end the call control program when the determination result is positive, otherwise, execute the standby antenna control module 402 when the determination result is negative.

Specifically, when the network silence problem is not detected in the call process, it indicates that the call at this time has no silence problem, or the call at this time has a silence problem, but the call is not caused by the network problem, that is, the call does not belong to the network silence problem, in these two cases, the call control method of the present invention further detects whether the call quality of the current call is qualified, if the call quality is qualified, it indicates that the current call is normal, and ends the flow, otherwise, if the call quality is detected to be unqualified, the step S602 is executed. The characterization parameters of the call quality include a plurality of parameters, such as a Bit Error Rate (BER), a bit error rate (Pe), a Frame Error Rate (FER), a block error rate (BLER), and the like, where the Bit Error Rate (BER) refers to a probability that a bit is transmitted in an error process in data transmission, the bit error rate (Pe) refers to a probability that a symbol is transmitted in a data transmission system in error, the Frame Error Rate (FER) refers to a probability that a frame is transmitted in an error process in data transmission, and the block error rate (BLER) refers to an error probability that a transmission block is subjected to CRC check, and the four characterization parameters are statistical values, that is, statistical averages over a relatively long period of time. When the call quality is determined, the determination may be performed through one or more of the above characterizing parameters, and the call quality is measured through the bit error rate in this embodiment. Specifically, the step of judging whether the call quality of the current call is qualified includes: (1) acquiring a bit error rate of the current call in a preset time period, wherein the bit error rate refers to the probability of transmitting errors of code elements in a data transmission system; (2) judging whether the bit error rate exceeds a preset threshold value or not; (3) and if the bit error rate exceeds a preset threshold value, judging that the conversation quality of the current conversation is unqualified, otherwise, judging that the current conversation is normal. It should be noted that, this embodiment only exemplifies a method for determining whether the call quality of the current call is qualified, and any method capable of determining whether the call quality is qualified in the prior art is applicable to the present invention.

In addition, in this embodiment, the standby antenna control module 402 is further configured to: controlling the standby antenna to enter a sleep mode after the step of switching the current antenna used for the current call to the target channel. After the channel switching of the current antenna (namely the default antenna) is finished, the standby antenna is controlled to enter the sleep mode from the working mode, so that resources can be saved, and unnecessary energy consumption is avoided.

Through the

module

401 and 404, the call control program provided by the present invention detects whether the current call has the network silence problem during the call, if the current call has the network silence problem, the standby antenna of the mobile terminal is started to search the target channel through the standby antenna, then a channel switching instruction is sent to the network end of the current call, and the current antenna used by the current call is switched to the target channel, so that the current antenna and the network end talk through the target channel, and when the network silence problem is not detected, the call control program further judges whether the call quality of the current call is qualified, and when the call quality of the current call is not detected, the standby antenna of the mobile terminal is started to execute the channel switching process, which not only solves the silence problem caused by the network problem, meanwhile, the situation of poor call quality is optimized, the call process is further improved, and the user experience is improved.

In addition, the present invention provides a call control method, which is applied to the mobile terminal shown in fig. 1 to 2, and the mobile terminal includes a memory and a processor. In order to implement the call control method of the present invention, the mobile terminal of the present invention has dual antennas, which are respectively marked as a first antenna and a second antenna, and under normal conditions, one of the antennas is used for network communication while the other antenna is in a sleep mode.

Fig. 5 is a flowchart illustrating a call control method according to a first embodiment of the present invention. In this embodiment, the execution order of the steps in the flowchart shown in fig. 5 may be changed and some steps may be omitted according to different requirements. The call control method comprises the following steps:

step S501, whether the current call has the network silence problem is detected in the call process, if the detection result is yes, step S502 is executed, otherwise, the process is ended.

The network silence problem refers to silence caused by network problems, and the reasons for generating the silence problem can be various in the conversation process, but the invention only optimizes the silence caused by the network problems. Specifically, in this embodiment, the step of detecting whether the current call has the network silence problem includes: (1) judging whether the voice data packets received by the mobile terminal are the same data packets or the same data packets with the same cycle; (2) if the judgment result is yes, the network silence problem of the current call is judged, otherwise, the silence problem does not occur or the silence problem occurs but is not caused by the network problem, and the two situations are not optimized by the method and the device. When the mobile terminal carries out communication, the mobile terminal receives a voice data packet sent by a communication opposite side in real time, under the condition of normal communication, the content of the voice data packet is not the same, and when the network silence problem occurs, the received voice data packet is a data packet which is the same in duration or a data packet which is the same in periodic cycle, so that whether the network silence problem occurs at present can be judged by detecting the content of the voice data packet. In addition, it should be noted that the step of detecting whether the current call has the network silence problem is only executed when the mobile terminal is in the call state.

Step S502, if the network silence problem occurs in the current conversation, the standby antenna of the mobile terminal is started to search a target channel through the standby antenna.

Step S503, sending a channel switching instruction to the network end of the current call, and switching the current antenna used in the current call to the target channel, so that the current antenna and the network end perform a call through the target channel.

Through the steps S501 to S503, in the call process, the call control method of the present invention detects whether a network silence problem occurs in a current call, if the network silence problem occurs, the standby antenna of the mobile terminal is started to search a target channel through the standby antenna, after the target channel is searched, a channel switching instruction is sent to a network end of the current call, and a current antenna used in the current call is switched to the target channel, so that the current antenna and the network end talk through the target channel, thereby realizing that when the current channel has a problem, the antenna is switched to another channel for communication, solving the silence problem caused by the network problem, and improving user experience.

Further, based on the first embodiment, a second embodiment of the call control method of the present invention is provided. Fig. 6 is a flowchart illustrating a call control method according to a second embodiment of the present invention. In this embodiment, the execution order of the steps in the flowchart shown in fig. 6 may be changed and some steps may be omitted according to different requirements. The call control method comprises the following steps:

step S601, detecting whether a network silence problem occurs in the current call during the call, if the detection result is no, executing step S602, otherwise executing step S603.

Step S602, determining whether the call quality of the current call is qualified, if the determination result is no, executing step S603, otherwise, ending the process.

Step S603, starting a standby antenna of the mobile terminal to search for a target channel through the standby antenna.

Step S604, sending a channel switching instruction to the network end of the current call, and switching the current antenna used by the current call to the target channel, so that the current antenna and the network end perform a call through the target channel.

Step S605, controlling the standby antenna to enter a sleep mode. Namely, after the channel switching of the current antenna (namely, the default antenna) is completed, the standby antenna is controlled to enter the sleep mode from the working mode, so that resources are saved, and unnecessary energy consumption is avoided.

Through the above steps S601 to S605, the call control method of the present invention detects whether the current call has the network silence problem during the call, if the current call has the network silence problem, the standby antenna of the mobile terminal is started to search the target channel through the standby antenna, then a channel switching instruction is sent to the network end of the current call, and the current antenna used by the current call is switched to the target channel, so that the current antenna and the network end talk through the target channel, and when the network silence problem is not detected, whether the call quality of the current call is qualified or not is further determined, and when the call quality of the current call is not detected, the standby antenna of the mobile terminal is started to execute the channel switching process, which not only solves the silence problem caused by the network problem, meanwhile, the situation of poor call quality is optimized, the call process is further improved, and the user experience is improved.
