Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 1, a schematic diagram of an implementation environment related to a voice call method according to various embodiments of the present invention is shown. As shown in fig. 1, the implementation environment includes a calling terminal 110, a backend server 120, a telephony operator 130, and a called terminal 140.
Calling terminal 110 may be a terminal with voice call capability, for example, a mobile phone. In practical implementation, the calling terminal 110 has the voice call client 111 installed therein, and the calling terminal 110 may initiate a voice call with the called terminal 140 through the voice call client 111. Alternatively, the Voice call client may initiate a Voice call with the called terminal 140 through VoIP (Voice over Internet Protocol). The calling terminal 110 may be connected to the backend server 120 through a wireless network.
The background server 120 is a background server for providing a service to the voice call client 111. The backend server 120 may be connected to the phone carrier 130 via a wired or wireless network. In practical implementation, the background server 120 may be one server or a server cluster composed of multiple servers.
Taking the background server 120 as a server cluster as an example, the background server 120 may include an RTP (Real-time Transport Protocol) server, a transcoding server, and a call server. The RTP server is used to communicate with the telephony operator 130, the transcoding server is used to transcode voice call information, and the call server is used to receive a call from the calling terminal 110 and initiate a call to the called terminal 130 to the telephony operator 130. Optionally, the backend server 120 may further include other servers, which is not limited in this embodiment.
The telephone carrier 130 may be a mobile, a universal, a telecom, or other carrier.
The called terminal 140 may also be a terminal with voice call capability, for example, a mobile phone. In actual implementation, the called terminal 140 may or may not have a voice call client installed therein, which is not limited in this embodiment. Also, the called terminal 140 may be a terminal in a PSTN (Public Switched Telephone Network).
Referring to fig. 2, a flowchart of a method of a voice call method according to an embodiment of the present invention is shown, and the present embodiment illustrates that the voice call method is used in the backend server 120 shown in fig. 1. As shown in fig. 2, the voice call method may include:
And step 204, converting the voice call information into the voice call information supported by the other terminal according to the first voice coding information and the second voice coding information.
In summary, in the voice call method provided in this embodiment, the background server obtains the first voice coding information of the calling terminal and the second voice coding information of the called terminal after receiving the voice call request sent by the calling terminal, and then converts the voice call information into the voice call information supported by another terminal according to the first voice coding information and the second voice coding information when receiving the voice call information sent by the calling terminal or the called terminal, and sends the converted voice call information to the another terminal; the problem that transcoding can be realized only after a voice call client is updated when a new coding type occurs in the prior art, and the flexibility is poor is solved; the background server can directly transcode according to the voice coding information at the two ends of the call without updating the voice call client, and the flexibility is improved.
Referring to fig. 3, a flowchart of a method of a voice call method according to an embodiment of the present invention is shown, and the present embodiment illustrates that the voice call method is used in the backend server 120 shown in fig. 1. As shown in fig. 3, the voice call method may include:
The calling terminal is provided with a voice call client, and when a user needs to perform voice call with other users, the user can initiate a voice call request for calling the called terminal through the voice call client in the calling terminal.
After a voice call client in a calling terminal initiates a voice call request, a background server may correspondingly receive the voice call request. The voice call request carries the identifier of the called terminal. For example, the mobile phone number carries the called terminal.
In practical implementation, the voice call request may further include first voice coding information supported by the calling terminal. Wherein the first speech coding information may include: the type of encoding of the encoder, or, the type of encoding and the encoding parameters used by the encoder. The coding type may be: talk, g711a, g729a, etc., and the encoding parameters may include at least one of a sampling rate, an encoding complexity, and a transmission interval for transmitting adjacent packets.
Optionally, since some encoders do not configure encoding parameters in actual implementation, the speech encoding information may only include the encoding type for this case. If the encoder configures the encoding parameters, the speech encoding newly includes the encoding type and the encoding parameters.
It should be noted that, the above is only exemplified by the encoding type and the encoding parameter being the above contents, optionally, the encoding type may also be another type, and the encoding parameter may also include other contents, which is not limited in this embodiment.
After receiving the voice call request, the background server may extract the identifier of the called terminal carried in the voice call request, determine an operator corresponding to the called terminal according to the identifier of the called terminal, and then obtain second voice encoding information of the called terminal from the determined operator. Optionally, the background server may send an information obtaining request to the operator, and receive second speech coding information returned by the operator, where the information obtaining request is used to request to obtain the second speech coding information of the called terminal.
For example, if the identifier of the called terminal is 158616xxx12, the background server may determine that the called terminal is a mobile user, and at this time, the background server may send an information acquisition request to the mobile operator and receive the second speech encoding information returned by the mobile operator.
It should be noted that the speech coding information of each user in the same operator may be the same or different, and the speech coding information of each user in different operators may also be the same or different, which is not limited in this embodiment. And when the voice coding information of each user in the same operator is different, the information acquisition request sent by the background server may include the identifier of the called terminal, and after receiving the information acquisition request, the operator determines the second voice coding information of the called terminal according to the identifier of the called terminal and returns the determined second voice coding information to the background server.
And step 304, receiving voice call information sent by the calling terminal or the called terminal.
In the voice communication process of the calling terminal and the called terminal, if the calling terminal sends out voice, the background server can correspondingly send voice communication information to a voice communication client in the calling terminal; if the called terminal sends out voice, the called terminal sends the voice call information to the operator, and then the operator can forward the voice call information to the background server, and the background server correspondingly receives the voice call information.
And 305, converting the voice call information into the voice call information supported by the other terminal according to the first voice coding information and the second voice coding information.
After the background server receives the voice call information, the background server may convert the voice call information into voice call information supported by another terminal.
For example, if the voice call information is information sent by the calling terminal, the background server converts the voice call information into voice call information corresponding to second voice coding information of the called terminal; and if the voice call information is the information sent by the called terminal, the background server converts the voice call information into the voice call information corresponding to the first voice coding information of the calling terminal.
It should be noted that, if the first speech encoding information is the same as the second speech encoding information, the background server does not need to perform conversion, and the background server directly forwards the first speech encoding information and the second speech encoding information, which is not described herein again.
After the conversion, the background server may send the converted voice call information to another terminal.
After the other terminal receives the converted voice call information, the other terminal can successfully analyze the voice call information, and normal call is guaranteed.
In the voice call process, problems such as network delay, network jitter or network packet loss may occur along with changes of the call network, and in order to avoid the problems, either party of the two parties of the call can automatically update the own voice coding information and send a coding information updating request to the background server. Correspondingly, the background server can receive the coding information updating request sent by the target terminal.
In the process of communication, the two parties of the communication can monitor the tone quality of the communication in real time, obtain the voice coding information corresponding to the current tone quality according to the corresponding relation between the tone quality and the voice coding information, and send a coding information updating request to the background server if the obtained voice coding information is different from the currently used voice coding information.
Since the coding type does not usually change, the speech coding information to be updated may be the coding parameters in practical implementation. When the encoding parameter is encoding complexity, the tone quality and the encoding complexity are in positive correlation; when the coding parameter is a packet transmission interval, the tone quality and the packet transmission interval are in a negative correlation relationship; when the coding parameters include a sampling rate, the sound quality is positively correlated with the sampling rate. Optionally, the sound quality within a certain range may correspond to the same speech coding information, which is not limited in this embodiment.
And 308, updating the voice coding information corresponding to the target terminal according to the updated voice coding information.
And after the background server receives the coding information updating request, updating the corresponding voice coding information. Thereafter, the background server may transcode according to the updated speech coding information, which is not described herein again in this embodiment.
It should be noted that step 307 and step 308 are optional steps, and may or may not be executed in actual implementation, and this embodiment is only executed after step 306, and optionally may also be executed after step 302, which is not described herein again.
Another point to be described is that after the call is ended, the calling terminal may send a call end instruction to the background server, and after the background server receives the call end instruction, the background server deletes the previously received first speech coding information of the calling terminal and the second speech coding information of the called terminal.
In summary, in the voice call method provided in this embodiment, the background server obtains the first voice coding information of the calling terminal and the second voice coding information of the called terminal after receiving the voice call request sent by the calling terminal, and then converts the voice call information into the voice call information supported by another terminal according to the first voice coding information and the second voice coding information when receiving the voice call information sent by the calling terminal or the called terminal, and sends the converted voice call information to the another terminal; the problem that transcoding can be realized only after a voice call client is updated when a new coding type occurs in the prior art, and the flexibility is poor is solved; the background server can directly transcode according to the voice coding information at the two ends of the call without updating the voice call client, and the flexibility is improved.
Meanwhile, the target terminal can update the corresponding voice coding information in the transcoding server, so that both parties in the call can successfully analyze the voice coding information after receiving the voice call information of the opposite terminal, and the call can be normally carried out.
The above embodiment is only an example in which the voice call method is used for a backend server, and the backend server is a server. Optionally, the background server may also be a server cluster including an RTP server, a transcoding server, and a call server, at this time, referring to fig. 4A, the voice call method may include:
step 401, the call server receives a voice call request sent by a calling terminal.
After the voice call client in the calling terminal sends out the voice call request, the call server may correspondingly receive the voice call request. The voice call request carries first voice coding information of a calling terminal and an identifier of a called terminal. Optionally, the voice call client may send the voice call request through SIP (Session Initiation Protocol) signaling.
As shown in fig. 4B, the voice call client may access to the call server through signaling. Accordingly, the call server receives the voice call request.
Step 402, the call server sends the first voice coding information carried in the voice call request to the RTP server.
Optionally, the call server may send the address of the RTP server to the calling terminal while sending the first voice coding information to the RTP server, so that the subsequent calling terminal may send the voice call information to the RTP server according to the address of the RTP server.
In step 403, the RTP server receives the first speech coding information.
Step 404, the call server obtains the second voice coding information from the operator according to the identifier of the called terminal carried in the voice call request.
This step is similar to step 303 in the above embodiment, and this embodiment is not described herein again.
In step 405, the call server synchronizes the second vocoded information to the RTP server.
The RTP server receives the second vocoded information, step 406.
Step 407, the RTP server sends the first voice coding information and the second voice coding information to the transcoding server.
After the RTP server obtains the first speech coding information and the second speech coding information, the RTP server may send the first speech coding information and the second speech coding information to the transcoding server.
It should be noted that, above is only an example that the RTP server acquires the first speech coding information first and then acquires the second speech coding information, optionally, the RTP server may also acquire the first speech coding information first and then acquire the second speech coding information, or the RTP server acquires both of the first speech coding information and the second speech coding information at the same time, which is not limited in this embodiment.
Step 408, the transcoding server feeds back the identification information to the RTP server.
After receiving the first voice coding information and the second voice coding information, the transcoding server uniquely allocates one piece of identification information to the first voice coding information and the second voice coding information, and feeds back the identification information to the RTP server. The identification information is used for uniquely identifying the corresponding relation between the first voice coding information and the second voice coding information.
In step 409, the RTP server receives the identification information fed back by the transcoding server.
In step 410, the RTP server receives voice call information sent by the calling terminal or the called terminal.
In the process of communication, the calling terminal or the called terminal can send voice communication information, and correspondingly, the RTP server can receive the voice communication information.
Specifically, when the calling terminal sends the voice call information, the voice call client in the calling terminal may directly send the voice call information to the RTP server. And when the called terminal sends the voice call information, the called terminal can send the voice call information to the RTP server through the operator.
In step 411, the RTP server sends the voice call information and the identification information to the transcoding server.
After the RTP server receives the voice call information, the RTP server may send the voice call information and the identification information to the transcoding server.
In step 412, the transcoding server converts the voice call information into the voice call information supported by the other terminal according to the identification information.
Step 413, the transcoding server sends the converted voice call information to the RTP server.
In step 414, the RTP server sends the converted voice call information to another terminal.
Step 415, after the call is ended, the RTP server sends a call end instruction to the transcoding server, where the call end instruction includes the identification information.
And step 416, the transcoding server deletes the first voice coding information and the second voice coding information corresponding to the identification information.
After receiving the call ending instruction, the transcoding server extracts the identification information in the call ending instruction, deletes the first voice coding information and the second voice coding information corresponding to the identification information, and releases the storage space required for storing the information.
In addition, similar to the above embodiment, the calling terminal or the called terminal may request to update its own vocoded information, and at this time, referring to fig. 4C, the voice call method may further include the following steps:
in step 417, the RTP server receives the coding information update request sent by the target terminal.
Optionally, when the target terminal is the calling terminal, after the calling terminal sends the coding information update request to the call server through signaling access, the call server may forward the coding information update request to the RTP server, and the RTP server correspondingly receives the coding information update request sent by the call server. When the target terminal is the called terminal, the called terminal may send the coding information update request to the call server, and the call server forwards the coding information update request to the RTP server, and accordingly, the RTP server receives the coding information update request forwarded by the call server.
In step 418, the RTP server forwards the coding information update request to the transcoding server.
And step 419, the transcoding server updates the voice coding information of the target terminal according to the updated voice coding information in the coding information updating request.
Please refer to fig. 4D, which illustrates a schematic diagram of the update process of the speech coding information.
In summary, in the voice call method provided in this embodiment, the background server obtains the first voice coding information of the calling terminal and the second voice coding information of the called terminal after receiving the voice call request sent by the calling terminal, and then converts the voice call information into the voice call information supported by another terminal according to the first voice coding information and the second voice coding information when receiving the voice call information sent by the calling terminal or the called terminal, and sends the converted voice call information to the another terminal; the problem that transcoding can be realized only after a voice call client is updated when a new coding type occurs in the prior art, and the flexibility is poor is solved; the background server can directly transcode according to the voice coding information at the two ends of the call without updating the voice call client, and the flexibility is improved.
After receiving the first voice coding information and the second voice coding information, the transcoding server allocates identification information for representing the corresponding relationship between the first voice coding information and the second voice coding information, and feeds the identification information back to the RTP server, so that after the RTP server receives the voice call information at one end, transcoding can be realized only by sending the voice call information and the identification information to the transcoding server, the first voice coding information and the second voice coding information do not need to be sent to the transcoding server every time, and transmission resources required to be consumed in the transmission process are reduced.
Meanwhile, the target terminal can update the corresponding voice coding information in the transcoding server, so that both parties in the call can successfully analyze the voice coding information after receiving the voice call information of the opposite terminal, and the call can be normally carried out.
Referring to fig. 5, a schematic structural diagram of a voice call apparatus according to an embodiment of the present invention is shown, and as shown in fig. 5, the voice call apparatus may include: a receiving module 510, an obtaining module 520, a converting module 530, and a sending module 540.
