Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments, and all other embodiments obtained by those skilled in the art without making any inventive effort based on the embodiments of the present invention are within the scope of protection of the present invention.
As described above, in the related art, a mobile terminal generally sets a communication mode, i.e., transmits/receives voice data packets in a high quality coding format or transmits/receives voice data packets in a low quality coding format. Because the network signal quality of the area where each mobile terminal is located is different and has randomness, if the network signal quality of the communication of different mobile terminals is different, it is difficult to ensure the call quality of all the mobile terminals.
In order to solve the above technical problems, 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 in the first mobile terminal and the 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 adjustment of the first voice data stream to a receiving end in the first mobile terminal and the second mobile terminal, so as to ensure call qualities 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 of a mobile terminal, which 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 communicate with each other;
step 102: when the first network signal quality and the second network signal quality are different, processing the received coding format of the first voice data stream to obtain a second voice data stream; the first voice data stream is sent by a sending end in the first mobile terminal and the second mobile terminal, and the first voice data stream and the second voice data stream both comprise a plurality of voice data packets;
step 104: and sending the second voice data stream to receiving ends in the first mobile terminal and the second mobile terminal.
In the embodiment of the invention, first network signal quality of a first mobile terminal and second network signal quality of a second mobile terminal which are in communication are determined, and when the first network signal quality and the second network signal quality are different, the coding format of a first voice data stream sent by a sending end in the received first mobile terminal and 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 individual steps shown in fig. 1 are performed is described below.
For step 100:
it should be noted that, in this step, the first network signal quality of the first mobile terminal when communicating and the second network signal quality of the second mobile terminal when communicating are both reported to the core network device before the two are communicated. For example, the network signal quality of the first mobile terminal and the second mobile terminal when not in communication may be reported to the core network device in advance in a manner of sending heartbeat packets in a certain time period; for another example, the first network signal quality of the first mobile terminal (i.e., the calling terminal) when not in communication may be reported to the core network device in advance in a manner of sending a heartbeat packet for a certain period of time, and the second network signal quality of the second mobile terminal may wait until the core network device receives the call request initiated by the first mobile terminal, and the core network device sends a test packet for testing the second network signal quality to the second mobile terminal, so as to determine according to the time difference between sending the test packet by the core network device and receiving the test packet.
In some embodiments, step 100 may include:
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 the first mobile terminal and a second identifier of the second mobile terminal;
determining the first network signal quality of the first mobile terminal during communication based on the network signal quality of each mobile terminal and the first identifier;
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 in a certain period of time 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 updated last by the first mobile terminal from the network signal quality of each mobile terminal, 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 during communication is determined based on a second identifier in the call request.
In step 100, embodiments of the present invention provide two ways of determining the signal quality of the second network, which are described below.
Mode one:
in a first aspect, the step of determining, based on the second identifier, a second network signal quality of the second mobile terminal when communicating 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 last by the second mobile terminal 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 when communicating.
Mode two:
in a second mode, the step of determining the second network signal quality of the second mobile terminal during communication based on the second identifier may include:
sending a test packet to a second mobile terminal;
in response to receiving the test packet sent by the second mobile terminal, determining a time difference between a sending time and a receiving time of the test packet;
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 a 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 in the core network device.
For 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, 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 the manner in which the second voice data stream is obtained in both cases is described below.
Case one:
in a first case, when the quality of the first network signal is higher than the quality of the second network signal, the step of "processing the received coding format of the 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 may be obtained by the following equation:
wherein V is 2 The unit is kbit/s for the bandwidth of the second voice data stream; v (V) 1 The unit is kbit/s for the bandwidth of the first voice data stream; r is R 1 The round trip time of the heartbeat packet in the first mobile terminal and the core network equipment in the first network signal quality is s; r is R 2 The round trip time of the test packet or the heartbeat packet in the second network signal quality in the second mobile terminal and the core network equipment is s; k (k) 1 The data transmission rate of the first network signal quality when sending the heartbeat packet is given in kbit/s; k (k) 2 And the 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.
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 may be obtained by the following formula:
wherein T is 2 The unit is s for the time interval between two adjacent voice data packets of the second voice data stream; v (V) 1 The unit is s for the time interval between two adjacent voice data packets of the first voice data stream; r is R 1 The round trip time of the heartbeat packet in the first mobile terminal and the core network equipment in the first network signal quality is s; r is R 2 The round trip time of the test packet or the heartbeat packet in the second network signal quality in the second mobile terminal and the core network equipment is s; k (k) 1 The data transmission rate of the first network signal quality when sending the heartbeat packet is given in kbit/s; k (k) 2 And the 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 23.05kbit/s and a time interval of 20ms between two adjacent voice data packets may be converted into a second voice data stream with a low quality encoding format of 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 bandwidth of the first voice data stream is reduced, and the time interval between two adjacent voice data packets of the first voice data stream is increased, so as to obtain a second voice data stream with lower quality than the first voice data stream, so as to avoid the situation that the second mobile terminal under the quality of the second network signal loses words and breaks voice during communication, thereby ensuring the call quality of all the mobile terminals.
It should be noted that, when the first network signal quality is higher than the second network signal quality, if the first voice data stream is sent by the second mobile terminal with the second network signal quality, 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 compared with the first voice data stream, so as to avoid the situation that the voice quality effect of the first mobile terminal with the first network signal quality is more sacrificed when communicating, thereby ensuring the call quality of all the mobile terminals.
And a second case:
in the second case, when the first network signal quality is lower than the second network signal quality, the step of "processing the received coding format of the first voice data stream to obtain the second voice data stream" may include:
for 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 low quality encoding format of 6.60kbit/s and a time interval of 60ms between two adjacent voice data packets may be converted into a second voice data stream with a high quality encoding format of 23.05kbit/s and a time interval of 20ms between two adjacent voice data packets.
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 bandwidth of the first voice data stream is increased and the time interval between two adjacent voice data packets of the first voice data stream is reduced to obtain a second voice data stream with higher quality than the first voice data stream, so as to avoid the situation that the voice quality effect of the second mobile terminal under the quality of the second network signal is sacrificed greatly during communication, thereby ensuring the call quality of all the mobile terminals.
It should be noted that, when the first network signal quality is lower than the second network signal quality, if the first voice data stream is sent by the second mobile terminal with 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 with lower quality than the first voice data stream, so as to avoid the situation that the first mobile terminal with the first network signal quality loses words and has intermittent voice during communication, thereby ensuring the call quality of all the mobile terminals.
For step 104:
in this embodiment, the second voice data stream corresponding to the first voice data stream obtained in step 102 according to the first network signal quality and the second network signal quality may be sent to the receiving ends in 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 the 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 3 are provided for the first mode and the second mode, respectively. Fig. 2 and 3 are respectively described below.
For example, as shown in fig. 2, which is a three-terminal interaction diagram provided in this embodiment, each mobile terminal sends a heartbeat packet to a core network device based on a certain period of time, so as to report the network signal quality of each mobile terminal, and when a first mobile terminal initiates a call request, the core network device determines the network signal quality reported by the first mobile terminal last time 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 which is reported by the second mobile terminal last time as second network signal quality; then, the core network equipment sends the 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; after that, the second mobile terminal can 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 that the mutual communication between the first mobile terminal and the second mobile terminal is realized, and the communication quality of all the mobile terminals can be ensured.
As another example, as shown in fig. 3, which is another three-terminal interaction diagram provided in this embodiment, each mobile terminal sends a heartbeat packet to the core network device based on a certain period of time, 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 reported by the first mobile terminal last time 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 the 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; after that, the second mobile terminal can 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 that the mutual communication between the first mobile terminal and the second mobile terminal is realized, and the communication quality of all the mobile terminals can be ensured.
