Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention, and based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the scope of the present invention.
As described above, in the related art, the mobile terminal generally sets a communication mode, i.e., transmits/receives voice data packets in a high-quality encoding format or transmits/receives voice data packets in a low-quality encoding format. Because the network signal quality of the area where each mobile terminal is located is different and random, if the network signal quality of different mobile terminals during communication is different, it is difficult to ensure the call quality of all the mobile terminals.
In order to solve the above technical problem, the inventor may consider setting a core network device, so that the core network device adjusts a coding format of a first voice data stream sent by a sending end of a first mobile terminal and a second mobile terminal according to respective network signal qualities of the first mobile terminal and the second mobile terminal, and sends a second voice data stream obtained after the first voice data stream is adjusted to a receiving end of the first mobile terminal and the second mobile terminal, thereby ensuring the call quality of all the mobile terminals.
Specific implementations of the above concepts are described below.
Referring to fig. 1, an embodiment of the present invention provides a communication method for a mobile terminal, where the method is applied to a core network device, and the method includes:
Step 100: determining a first network signal quality of a first mobile terminal during communication and a second network signal quality of a second mobile terminal during communication; the first mobile terminal and the second mobile terminal are communicated with each other;
step 102: when the first network signal quality and the second network signal quality are different, processing the coding format of the received first voice data stream to obtain a second voice data stream; the first voice data stream is sent by sending terminals in a first mobile terminal and a second mobile terminal, and both the first voice data stream and the second voice data stream comprise a plurality of voice data packets;
step 104: and sending the second voice data stream to a receiving end in the first mobile terminal and the second mobile terminal.
In the embodiment of the invention, the first network signal quality of a first mobile terminal and the second network signal quality of a second mobile terminal which are communicating are firstly determined, and when the first network signal quality is different from the second network signal quality, the coding format of a first voice data stream sent by a sending end in the first mobile terminal and the second mobile terminal is processed to obtain a second voice data stream which is suitable for the network signal quality of a receiving end in the first mobile terminal and the second mobile terminal, so that the call quality of all the mobile terminals is ensured.
The manner in which the various steps shown in fig. 1 are performed is described below.
With respect to step 100:
it should be noted that, in this step, both the first network signal quality when the first mobile terminal is in communication and the second network signal quality when the second mobile terminal is in communication are reported to the core network device before the first mobile terminal and the second mobile terminal are in communication. For example, the network signal quality of the first mobile terminal and the second mobile terminal when not communicating may be reported to the core network device in advance in a manner of sending heartbeat packets at a certain time period; for another example, when the first network signal quality of the first mobile terminal (i.e., the calling terminal) is not in communication, the first network signal quality may be reported to the core network device in advance in a manner of sending a heartbeat packet at a certain time period, and the second network signal quality of the second mobile terminal may be determined according to a time difference between sending the test packet and receiving the test packet by the core network device by sending the test packet to the second mobile terminal by the core network device when the core network device receives a call request initiated by the first mobile terminal.
In some embodiments, step 100 may comprise:
determining the network signal quality of each mobile terminal based on the acquired heartbeat packets sent by different mobile terminals;
Receiving a call request initiated by a first mobile terminal to a second mobile terminal; the call request carries a first identifier of a first mobile terminal and a second identifier of a second mobile terminal;
determining the first network signal quality of the first mobile terminal during communication based on the network signal quality and the first identifier of each mobile terminal;
and determining the second network signal quality of the second mobile terminal during communication based on the second identifier.
In this embodiment, different mobile terminals send heartbeat packets to the core network device at a certain time period to update the network signal quality of each mobile terminal in real time, and when the core network device receives a call request initiated by a first mobile terminal to a second mobile terminal, the core network device determines, according to a first identifier in the call request, the network signal quality that is updated last time by the first mobile terminal from the network signal qualities of the mobile terminals, and determines the network signal quality as the first network signal quality of the first mobile terminal during communication. After the first network signal quality is determined, a second network signal quality of the second mobile terminal in communication is determined based on the second identifier in the call request.
In step 100, the embodiment of the present invention provides two ways to determine the signal quality of the second network, which are described below.
The method I comprises the following steps:
in the first mode, the step of "determining the second network signal quality of the second mobile terminal while communicating based on the second identifier" may include:
and determining the second network signal quality of the second mobile terminal during communication based on the network signal quality of each mobile terminal and the second identifier.
In this embodiment, the core network device determines, according to the second identifier in the call request, the network signal quality that is updated by the second mobile terminal last time from the network signal qualities of the mobile terminals, and determines the network signal quality as the second network signal quality of the second mobile terminal during communication.
The second method comprises the following steps:
in the second mode, the step of "determining the second network signal quality of the second mobile terminal while communicating based on the second identifier" may include:
sending a test packet to a second mobile terminal;
determining a time difference between a transmission time and a reception time of a test packet in response to receiving the test packet transmitted by the second mobile terminal;
and determining the second network signal quality of the second mobile terminal during communication based on the time difference.
In this embodiment, after the core network device identifies the second mobile terminal through the second identifier, the core network device sends the test packet to the second mobile terminal, and then after the second mobile terminal receives the test packet, the second mobile terminal returns the test packet to the core network device, and determines the second network signal quality of the second mobile terminal during communication according to the time difference between the sending time and the receiving time of the test packet at the core network device.
With respect to step 102:
it should be noted that, in some embodiments, the encoding format includes a bandwidth and a time interval between two adjacent voice data packets.
In this embodiment, the bandwidth of the first voice data stream and the time interval between two adjacent voice data packets are changed to obtain the second voice data stream adapted to the network signal quality of the receiving end, so as to ensure the call quality of all the mobile terminals.
In step 102, the embodiments of the present invention provide two cases, "when the first network signal quality is higher than the second network signal quality", and "when the first network signal quality is lower than the second network signal quality", and a description is given below of a manner of obtaining the second voice data stream in these two cases.
The first condition is as follows:
in case one, when the quality of the first network signal is higher than that of the second network signal, the step "processing the coding format of the received first voice data stream to obtain the second voice data stream" may include:
and aiming at each received complete first voice data stream, reducing the bandwidth of the first voice data stream and increasing the time interval between two adjacent voice data packets of the first voice data stream to obtain a second voice data stream corresponding to the first voice data stream.
In this embodiment, the bandwidth of the second voice data stream corresponding to the first voice data stream can be obtained by the following formula:
wherein, V2The bandwidth of the second voice data stream is defined as kbit/s; v1The unit is kbit/s which is the bandwidth of the first voice data stream; r is1The unit is s, which is the round-trip time of the heartbeat packet in the first network signal quality between the first mobile terminal and the core network equipment; r is2The round-trip time of a test packet or a heartbeat packet in the signal quality of the second network between the second mobile terminal and the core network equipment is s; k is a radical of1The unit is kbit/s which is the data transmission rate when the heartbeat packet is sent in the first network signal quality; k is a radical of 2The unit is kbit/s, which is the data transmission rate when the test packet or the heartbeat packet is sent in the second network signal quality.
In this embodiment, the time interval between two adjacent voice data packets of the second voice data stream corresponding to the first voice data stream can be obtained by the following formula:
wherein, T2For the second speech data streamThe time interval between two adjacent voice data packets is s; v1The time interval between two adjacent voice data packets of the first voice data stream is s; r is1The unit is s, which is the round-trip time of the heartbeat packet in the first network signal quality between the first mobile terminal and the core network equipment; r2The round-trip time of a test packet or a heartbeat packet in the signal quality of the second network between the second mobile terminal and the core network equipment is s; k is a radical of1The unit is kbit/s which is the data transmission rate when the heartbeat packet is sent in the first network signal quality; k is a radical of2The unit is kbit/s for the data transmission rate when the test packet or the heartbeat packet is sent in the second network signal quality.
For example, a first voice data stream with a high quality encoding format of bandwidth 23.05kbit/s and a time interval of 20ms between two adjacent voice data packets can be converted into a second voice data stream with a low quality encoding format of bandwidth 6.60kbit/s and a time interval of 60ms between two adjacent voice data packets.
In this embodiment, when the quality of the first network signal is higher than that of the second network signal, for each received complete first voice data stream, the second voice data stream with lower quality than that of the first voice data stream is obtained by reducing the bandwidth of the first voice data stream and increasing the time interval between two adjacent voice data packets of the first voice data stream, so as to avoid the situations of word loss and voice interruption of the second mobile terminal with the second network signal quality during communication, thereby ensuring the communication quality of all the mobile terminals.
It should be noted that, the first voice data stream is sent by the sending end of the first mobile terminal and the second mobile terminal, and it can be understood that, when the quality of the first network signal is higher than that of the second network signal, if the first voice data stream is sent by the second mobile terminal at the quality of the second network signal, the two formulas can be used to increase the bandwidth of the first voice data stream and reduce the time interval between two adjacent voice data packets of the first voice data stream, so as to obtain the second voice data stream with higher quality than the first voice data stream, so as to avoid the situation that the tone quality effect of the first mobile terminal at the quality of the first network signal is greatly sacrificed during communication, thereby ensuring the communication quality of all the mobile terminals.
Case two:
in case two, when the quality of the first network signal is lower than that of the second network signal, the step "processing the coding format of the received first voice data stream to obtain the second voice data stream" may include:
and aiming at each received complete first voice data stream, increasing the bandwidth of the first voice data stream and reducing the time interval between two adjacent voice data packets of the first voice data stream to obtain a second voice data stream corresponding to the first voice data stream.
In this embodiment, the bandwidth of the second voice data stream and the time interval between two adjacent voice data packets can be obtained by the same formula as in case one.
For example, a first voice data stream with a bandwidth of 6.60kbit/s and a time interval of 60ms between two adjacent voice data packets in a low quality coding format can be converted into a second voice data stream with a bandwidth of 23.05kbit/s and a time interval of 20ms between two adjacent voice data packets in a high quality coding format.
In this embodiment, when the quality of the first network signal is lower than that of the second network signal, for each received complete first voice data stream, the second voice data stream with higher quality than the first voice data stream is obtained by increasing the bandwidth of the first voice data stream and reducing the time interval between two adjacent voice data packets of the first voice data stream, so as to avoid the situation that the tone quality effect of the second mobile terminal with the second network signal quality is greatly sacrificed during communication, thereby ensuring the call quality of all the mobile terminals.
It should be noted that, the first voice data stream is sent by the sending end of the first mobile terminal and the second mobile terminal, and it can be understood that, when the quality of the first network signal is lower than that of the second network signal, if the first voice data stream is sent by the second mobile terminal at the second network signal quality, the two formulas can be used to reduce the bandwidth of the first voice data stream and increase the time interval between two adjacent voice data packets of the first voice data stream, so as to obtain the second voice data stream at a lower quality than the first voice data stream, so as to avoid word loss and voice interruption of the first mobile terminal at the first network signal quality during communication, thereby ensuring the call quality of all the mobile terminals.
With respect to step 104:
in this embodiment, the second voice data stream corresponding to the first voice data stream, which is obtained according to the first network signal quality and the second network signal quality in step 102, may be sent to the receiving ends of the first mobile terminal and the second mobile terminal, so as to ensure the call quality of the mobile terminals under different network signal qualities, and improve user experience.
In this step, three-terminal interaction diagrams of the first mobile terminal, the second mobile terminal and the core network device as shown in fig. 2 and fig. 3 are provided for the first mode and the second mode, respectively. Fig. 2 and 3 will be described below.
For example, as shown in fig. 2, in a three-terminal interaction diagram provided in this embodiment, each mobile terminal sends a heartbeat packet to the core network device based on a certain time period, so as to report the network signal quality of each mobile terminal, and when the first mobile terminal initiates a call request, the core network device determines the network signal quality last reported by the first mobile terminal as the first network signal quality; then, the core network equipment sends the call request to the second mobile terminal, and determines the network signal quality reported last time by the second mobile terminal as the second network signal quality; then, the core network equipment sends a call response sent by the second mobile terminal to the first mobile terminal; when the first mobile terminal receives a call response, the first mobile terminal and the second mobile terminal can start communication, at the moment, the first mobile terminal sends a first voice data stream to the core network equipment, and the core network equipment processes the first voice data stream into a second voice data stream according to the first network signal quality and the second network signal quality and sends the second voice data stream to the second mobile terminal, so that the communication quality of the second mobile terminal is ensured; then, the second mobile terminal may send a new first voice data stream to the core network device, and the core network device processes the new first voice data stream into a new second voice data stream and sends the new second voice data stream to the first mobile terminal, so as to implement mutual communication between the first mobile terminal and the second mobile terminal, and ensure the call quality of all the mobile terminals.
For another example, as shown in fig. 3, another three-terminal interaction diagram provided in this embodiment is that each mobile terminal sends a heartbeat packet to the core network device based on a certain time period, so as to report the network signal quality of each mobile terminal, and when the first mobile terminal initiates a call request, the core network device determines the network signal quality last reported by the first mobile terminal as the first network signal quality; then, the core network equipment sends the call request to the second mobile terminal and sends a test packet to the second mobile terminal, and the core network equipment determines the second network signal quality of the second mobile terminal during communication according to the time difference between the sending time and the receiving time of the test packet; then, the core network equipment sends a call response sent by the second mobile terminal to the first mobile terminal; when the first mobile terminal receives a call response, the first mobile terminal and the second mobile terminal can start communication, at the moment, the first mobile terminal sends a first voice data stream to the core network equipment, and the core network equipment processes the first voice data stream into a second voice data stream according to the first network signal quality and the second network signal quality and sends the second voice data stream to the second mobile terminal, so that the communication quality of the second mobile terminal is ensured; then, the second mobile terminal may send a new first voice data stream to the core network device, and the core network device processes the new first voice data stream into a new second voice data stream and sends the new second voice data stream to the first mobile terminal, so as to implement mutual communication between the first mobile terminal and the second mobile terminal, and ensure the call quality of all the mobile terminals.
