Detailed Description

The technical solutions in the present application will be described clearly and completely with reference to the accompanying drawings in the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the 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.

Fig. 1 is a block diagram of a communication system according to the present application. As shown in fig. 1, the communication system includes: the system comprises a first terminal, a server and at least one second terminal. The first terminal can perform voice service data transmission with the second terminal through the server. Fig. 1 is a schematic diagram, and the communication system may further include other devices (e.g., network devices, core network devices, etc.), which are not shown in fig. 1. In addition, the number of the second terminals is not limited in the present application.

The server may be any server capable of processing voice services, and the server may be a server independent from the core network and located behind the core network.

The first and second terminals may be wireless terminals or wired terminals, and a wireless terminal may refer to a device that provides voice and/or other service data connectivity to a user, a handheld device having wireless connection capability, or other processing device connected to a wireless modem. Wireless terminals, which may be mobile terminals such as mobile telephones (or "cellular" telephones) and computers having mobile terminals, such as portable, pocket, hand-held, computer-included, or vehicle-mounted mobile devices, may communicate with one or more core networks via a Radio Access Network (RAN), which may exchange language and/or data with the RAN. For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like. A wireless Terminal may also be referred to as a system, a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), a Remote Terminal (Remote Terminal), an access Terminal (access Terminal), a User Terminal (User Terminal), a User Agent (User Agent), and a User Equipment (User device User Equipment), which are not limited herein.

Taking the communication system shown in fig. 1 as an example, in a VoLTE scenario, some terminals only support the AMR-WB voice format, some terminals only support the AMR-NB voice format, and some terminals support the two voice formats. Therefore, how to perform voice service data transmission between terminals is an urgent problem to be solved.

In view of the above, the present application provides a data transmission method, so that voice service data can be transmitted between terminals supporting different voice formats and between terminals supporting multiple voice formats. It is understood that the data transmission method provided in the present application includes, but is not limited to, the above VoLTE scenario. Any scene related to voice service data transmission between terminals supporting different voice formats or supporting multiple voice formats can adopt the data transmission method provided by the application. In addition, the speech formats referred to in this application include, but are not limited to, the AMR-WB speech format, AMR-NB speech format described above. The AMR-WB voice format can support various voice transmission rates. If AMR-WB voice formats with different voice transmission rates are supported between the terminals, the terminals are considered to support different voice formats. For example, terminal 1 supports the AMR-WB speech format with the speech transmission rate 1, and terminal 2 supports the AMR-WB speech format with the speech transmission rate 2, it is considered that different speech formats are supported between terminal 1 and terminal 2.

The following takes AMR-WB voice format and AMR-NB voice format as examples, and the technical solution of the present application is explained in detail through specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Fig. 2 is a schematic flow chart of a data transmission method provided in the present application. In this embodiment, a process of performing voice service data transmission between terminals is described by taking an example that a first terminal calls at least one second terminal as a first terminal. The first terminal supports at least one first voice format, and the second terminal supports at least one fourth voice format. The at least one first speech format referred to herein may include, for example, at least one of: AMR-NB voice format, AMR-WB voice format, and the like. Accordingly, the at least one fourth speech format referred to herein may include, for example, at least one of: AMR-NB voice format, AMR-WB voice format, and the like. The at least one fourth voice format supported by each second terminal may be the same or different. In some embodiments, the first terminal may also be referred to as a calling terminal or a speaking terminal, and the second terminal may be referred to as a listening terminal or a called terminal.

As shown in fig. 2, the method includes:

s101, the first terminal sends a request message to the server.

The request message is used for the first terminal to request to send voice service data to at least one second terminal, and indicates that the first terminal supports voice service data transmission with the second terminal by using at least one first voice format.

For example, if the first terminal has already performed Session Initiation Protocol (SIP) pre-establishment with the server, the request message may be an invite message or a refer message in the SIP protocol, for example. If the first terminal does not perform SIP pre-establishment with the server, the request message may be an invite message in the SIP protocol, for example.

S102, the server sends a response message to the first terminal.

And the response message is used for informing the first terminal to use the second voice format to encode the voice service data when the first terminal sends the voice service data to at least one second terminal. Illustratively, when the request message is an invite message or a refer message in the SIP protocol, the response message may be a 200ok message in the SIP protocol.

Said second speech format is one of at least one first speech format. For example, the second voice format is any one of the at least one first voice format (e.g., a first voice format, a last voice format, etc.), or the second voice format is one of the at least one first voice format supported by some or all of the at least one second terminal. That is, the second voice format exists in at least one fourth voice format supported by part or all of the at least one second terminal.

S103, the first terminal encodes the voice service data by using the second voice format to obtain the encoded voice service data.

And S104, the first terminal sends the coded voice service data to the server.

And S105, the server sends the coded voice service data to the second terminal according to the voice format supported by the second terminal.

Fig. 2 is a schematic flow chart illustrating a second terminal. The number of the second terminals is not limited in this embodiment.

Specifically, for a second terminal supporting a second voice format, the server directly sends the encoded voice service data to the second terminal. For a second terminal that does not support the second voice format, the server may transcode the encoded voice service data according to the voice format supported by the second terminal when performing voice service data transmission with the first terminal, and send the transcoded voice service data to the second terminal. That is, the server may directly forward the voice service data to the second terminal according to the voice format supported by the second terminal, or forward the voice service data to the second terminal after transcoding, so as to ensure that the second terminal can correctly decode the received voice service data. By the method, the transmission of voice service data can be carried out between the terminals supporting different voice formats and between the terminals supporting various voice formats.

According to the data transmission method provided by the application, the server can designate a second voice format used when the first terminal and the second terminal carry out voice service data transmission according to at least one first voice format supported by the first terminal, and can forward the voice service data in the voice format supported by the second terminal to the second terminal based on the voice format supported by the second terminal, so that the second terminal can correctly decode the received voice service data, and the transmission of the voice service data between terminals supporting different voice formats and between terminals supporting various voice formats is realized.

As in the foregoing embodiment, the server may notify the first terminal that the voice service data is encoded using the second voice format when the voice service data is transmitted to the at least one second terminal by transmitting a response message to the first terminal. The method for determining the second voice format by the server may be determined according to a specific scenario, and specifically may include the following scenarios:

the first scenario is: at least one second terminal is one and the second terminal supports at least one fourth voice format. I.e. a scenario where the first terminal calls the second terminal only.

In this scenario, the server may determine the second voice format by interacting with the second terminal during the establishment of the single call service. Fig. 3 is a schematic flow chart of another data transmission method provided in the present application. As shown in fig. 3, before the step S102, the method may further include:

s201, the server sends a request message to the second terminal.

The request message may be a request message sent by the first terminal to the server.

S202, the second terminal selects a fourth voice format from at least one fourth voice format supported by the second terminal as a third voice format according to the at least one first voice format.

The third voice format is the same one of the at least one first voice format and the at least one fourth voice format, or the third voice format is one of the at least one fourth voice format. That is, when there is an intersection between at least one first speech format and at least one fourth speech format, one of the speech formats in the intersection may be selected as the third speech format. In the absence of an intersection between the at least one first speech format and the at least one fourth speech format, a fourth speech format of the at least one fourth speech format may be selected as the third speech format.

It is to be understood that, if the at least one fourth voice format supported by the second terminal only includes one fourth voice format, the second terminal may use the fourth voice format directly as the third voice format.

S203, the second terminal sends an initial response message to the server.

The initial response message is used for informing the second terminal that the second terminal supports the voice service data transmission with the first terminal by using the third voice format.

For example, when the request message is an invite message or a refer message in the SIP protocol, the initial response message may be a 200ok message in the SIP protocol.

S204, when the third voice format is one of the at least one first voice format, the server takes the third voice format as the second voice format and takes the initial response message as the response message, and when the third voice format is not one of the at least one first voice format, one voice format is selected from the at least one first voice format as the second voice format and generates the response message according to the second voice format.

When the third voice format is the voice format of the at least one first voice format, it indicates that the same voice format is supported between the first terminal and the second terminal, so the server can directly send the initial response message to the first terminal as the aforementioned response message, so as to instruct the first terminal to encode the voice service data using the third voice format when sending the voice service data to the second terminal through the message. That is, the third voice format is the second voice format.

Accordingly, since the second terminal supports using the second voice format, that is, the second terminal can correctly decode the voice service data encoded using the second voice format. Therefore, after the server receives the voice service data which is sent by the first terminal and coded by using the second voice format, the coded voice service data can be directly forwarded to the second terminal. In this way, after receiving the encoded voice service data, the second terminal may decode the encoded voice service data according to the third voice format (i.e., the second voice format).

When the third voice format is not the voice format in the at least one first voice format, it indicates that the voice formats supported by the first terminal and the second terminal are different, so that the server may select one voice format as the second voice format from the at least one first voice format supported by the first terminal, and generate a response message according to the second voice format and send the response message to the first terminal, so as to instruct, through the message, the first terminal to encode the voice service data using the second voice format when sending the voice service data to the second terminal. That is, the third speech format is not the second speech format.

Accordingly, since the second terminal does not support the use of the second voice format, that is, the second terminal cannot correctly decode the voice service data encoded using the second voice format. Therefore, after the server receives the voice service data which is sent by the first terminal and encoded by using the second voice format, the server can transcode the encoded voice service data according to the third voice format indicated by the initial response message through the second terminal and send the transcoded voice service data to the second terminal. Thus, after receiving the transcoded voice service data, the second terminal can decode the transcoded voice service data according to the third voice format.

By the method, in a scene that the first terminal singly calls the second terminal, the server can determine the second voice format used by the first terminal and the second terminal when the voice service data is transmitted by interacting with the second terminal, and can forward the voice service data in the voice format supported by the second terminal to the second terminal based on the voice format supported by the second terminal, so that the second terminal can correctly decode the received voice service data, and the transmission of the voice service data between terminals supporting different voice formats and between terminals supporting multiple voice formats is realized.

The second scenario is: the number of the at least one second terminal is multiple, the multiple second terminals do not perform SIP pre-establishment with the server, and each second terminal supports at least one fourth voice format. Namely, the first terminal group calls a plurality of second terminals, and the plurality of second terminals do not perform SIP pre-establishment with the server.

In this scenario, the server may select one first voice format as the second voice format from at least one first voice format supported by the first terminal after receiving the request message sent by the first terminal. For example, the server may treat a first one of the at least one first voice format as the second voice format. In this embodiment, at least one fourth voice format supported by each second terminal may be the same or different.

Fig. 4 is a schematic flowchart of another data transmission method provided in the present application. As shown in fig. 4, in this scenario, after the step S102, the method may further include:

s301, the server sends a request message to each second terminal.

The request message may be a request message sent by the first terminal to the server.

S302, the server receives an initial response message sent by each second terminal, wherein the initial response message is used for informing the second terminal that the second terminal supports the use of a third voice format for carrying out voice service data transmission with the first terminal, and the third voice format is one of at least one fourth voice format supported by the second terminal.

After receiving the request message sent by the server, each second terminal may perform the action shown in step S202, which is not described herein again.

S303, the server records a third voice format corresponding to each second terminal.

After receiving the voice service data encoded by using the second voice format and sent by the first terminal, the server may execute, according to the recorded third voice format corresponding to each second terminal, an operation of sending the voice service data to each second terminal:

for example, when the third voice format corresponding to the second terminal is the same as the second voice format, the server sends the encoded voice service data to the second terminal. Accordingly, after receiving the encoded voice service data, the second terminal may decode the encoded voice service data according to a third voice format (i.e., the second voice format).

Or, when the third voice format corresponding to the second terminal is different from the second voice format, the server transcodes the coded voice service data according to the third voice format and sends the transcoded voice service data to the second terminal. Correspondingly, after receiving the transcoded voice service data, the second terminal may decode the transcoded voice service data according to the third voice format.

By the method, in a scene that the first terminal group calls a plurality of second terminals, if the second terminals do not perform SIP pre-establishment with the server, the server can select one first voice format from at least one first voice format supported by the first terminal by itself to serve as a second voice format used when the first terminal performs voice service data transmission with the second terminal, and can forward the voice service data in the voice format to the second terminal based on the voice format reported by the second terminal, so that the second terminal can correctly decode the received voice service data, and the transmission of the voice service data between the terminals supporting different voice formats and between the terminals supporting a plurality of voice formats is realized.

The third scenario is: the number of the at least one second terminal is multiple, and the at least one second terminal is pre-established with the server through SIP. Wherein each second terminal supports a fourth voice format. That is, the first terminal group calls a plurality of second terminals, each second terminal supports a fourth voice format, and the plurality of second terminals and the server perform the SIP pre-established scenario.

In this scenario, after receiving the request message sent by the first terminal, the server may determine the second voice format according to at least one first voice format supported by the first terminal and a fourth voice format supported by each second terminal. Fig. 5 is a schematic flowchart of another data transmission method provided in the present application. As shown in fig. 5, before the step S102, the method may further include:

s401, the server classifies at least one second terminal according to a fourth voice format supported by each second terminal, and the voice formats supported by the second terminals in the same class are the same.

Illustratively, the at least one second terminal includes 4 terminals, which are respectively a second terminal a, a second terminal B, a second terminal C, and a second terminal D, where the fourth voice format supported by the second terminal a, the second terminal B, and the second terminal C is the same, and the fourth voice format supported by the second terminal D is different from the second terminal a, the second terminal B, and the second terminal C. The server may classify the second terminal a, the second terminal B, and the second terminal C into one class and the second terminal D into one class.

Optionally, before performing S401, the method may further include: the server acquires a fourth voice format supported by each second terminal. For example, the server may obtain the fourth voice format supported by each second terminal when performing SIP pre-establishment (e.g., a registration procedure or a login procedure) with each second terminal. For example, the server may send a request message to the second terminal to request to acquire the fourth voice format supported by the second terminal. The second terminal may send a response message to the server after receiving the request message. Wherein the response message may indicate a fourth voice format supported by the second terminal. The request message may be, for example, an invite message in the SIP protocol, and the response message may be, for example, a 200ok message in the SIP protocol.

S402, when the fourth voice format corresponding to the class with the largest number of terminals belongs to at least one first voice format, the server takes the fourth voice format corresponding to the class with the largest number of terminals as a second voice format; or when the fourth voice format corresponding to the class with the largest number of terminals does not belong to the at least one first voice format, the server selects one first voice format from the at least one first voice format as the second voice format.

Corresponding to the example in S401, when the fourth voice format supported by the second terminal a, the second terminal B, and the second terminal C also exists in at least one first voice format supported by the first terminal, the server may use the fourth voice format supported by the second terminal a, the second terminal B, and the second terminal C as the second voice format. When the fourth voice format supported by the second terminal a, the second terminal B, and the second terminal C does not exist in the at least one first voice format supported by the first terminal, the server may select one first voice format from the at least one first voice format supported by the first terminal as the second voice format.

And S403, the server sends a multicast notification message to the second terminal supporting the second voice format, where the multicast notification message is used to notify the second terminal supporting the second voice format, and the server sends voice service data to the second terminal supporting the second voice format in a multicast mode.

Accordingly, the second terminal supporting the second voice format may listen to the multicast channel after receiving the multicast notification message sent by the server.

In this scenario, after receiving the voice service data encoded in the second voice format and sent by the first terminal, the server may multicast the encoded voice service data to a second terminal supporting the second voice format. That is, the server may broadcast the encoded voice service data through the multicast channel, so that the second terminal supporting the second voice format receives the encoded voice service data from the multicast channel. Accordingly, after receiving the encoded voice service data, the second terminal supporting the second voice format may decode the encoded voice service data according to the second voice format.

S404, the server establishes a unicast channel for the second terminal which does not support the second voice format.

The execution sequence of steps S403 and S404 may not be sequential. For example, S403 may be executed first and then S404 may be executed, S404 may be executed first and then S403 may be executed, or both may be executed.

In this scenario, after receiving the voice service data encoded in the second voice format and sent by the first terminal, the server may transcode the encoded voice service data according to a fourth voice format supported by the second terminal that does not support the second voice format, and send the transcoded voice service data to the second terminal that does not support the second voice format through a unicast channel.

Correspondingly, after receiving the transcoded voice service data, the second terminal which does not support the second voice format can decode the transcoded voice service data according to the fourth voice format supported by the second terminal.

By the method, in the scene that the first terminal group calls a plurality of second terminals, if the second terminals have SIP pre-established with the server and each second terminal only supports a fourth voice format, the server may determine a second voice format used when the first terminal performs voice service data transmission with the second terminal according to a fourth voice format supported by the second terminal and at least one first voice format supported by the first terminal, and may determine a voice format of voice service data transmitted to the second terminal based on whether the second terminal supports the second voice format, and a sending mode, so that the second terminal can correctly decode the received voice service data, and the transmission of the voice service data between terminals supporting different voice formats and between terminals supporting multiple voice formats is realized.

The fourth scenario is as follows: the number of the at least one second terminal is multiple, and the at least one second terminal is pre-established with the server through SIP. And each second terminal supports at least one fourth voice format, and the at least one fourth voice format supported by each second terminal is the same as the at least one first voice format supported by the first terminal. That is, the first terminal group calls a plurality of second terminals, at least one fourth voice format supported by each second terminal is the same as at least one first voice format supported by the first terminal, and the plurality of second terminals and the server perform a SIP pre-established scenario.

In this scenario, after receiving the request message sent by the first terminal, the server may determine whether at least one fourth voice format supported by each second terminal is the same as at least one first voice format supported by the first terminal according to at least one first voice format supported by the first terminal and at least one fourth voice format supported by each second terminal. When the first voice format is the same as the second voice format, the server can select one first voice format from at least one first voice format supported by the first terminal as the second voice format. For example, the server may treat a first one of the at least one first voice format as the second voice format.

Optionally, before determining whether the at least one fourth voice format supported by each second terminal is the same as the at least one first voice format supported by the first terminal according to the at least one first voice format supported by the first terminal and the at least one fourth voice format supported by each second terminal, the server may further obtain the fourth voice format supported by each second terminal, and a specific implementation manner may refer to the foregoing description about obtaining the fourth voice format supported by the second terminal, which is not described herein again.

Since at least one fourth voice format supported by each second terminal is the same as at least one first voice format supported by the first terminal, it is described that the second terminal can correctly decode the voice service data regardless of which voice format the first terminal employs to transmit the voice service data to the second terminal. Therefore, the server may send a multicast notification message to each second terminal, where the multicast notification message is used to notify the second terminals, and the server sends the voice service data to the second terminals in a multicast manner.

In this way, after the server receives the voice service data encoded by using the second voice format and sent by the first terminal, the encoded voice service data can be directly multicast (also referred to as broadcast) to each second terminal through a multicast channel. Correspondingly, after receiving the encoded voice service data multicast by the server, the second terminal may decode the encoded voice service data according to at least one fourth voice format supported by the second terminal. That is, the second terminal may adaptively adjust the voice format of the decoder according to at least one fourth voice format supported by the second terminal and the frame format in the voice service data, so as to decode the encoded voice service data.

Through the method, in a scenario that the first terminal group calls a plurality of second terminals, if the second terminals are pre-established with the server in an SIP mode and at least one fourth voice format supported by each second terminal is the same as at least one first voice format supported by the first terminal, the server can designate a second voice format used when the first terminal and the second terminal perform voice service data transmission according to the at least one first voice format supported by the first terminal, and directly multicast the encoded voice service data to each second terminal after receiving the encoded voice service data sent by the first terminal, so that the second terminal can adaptively decode the received voice service data, and the transmission of the voice service data among the terminals supporting a plurality of voice formats is realized.

In addition, in the scenario of group calling multiple second terminals (i.e. the second scenario to the fourth scenario), when the first terminal of the group calling multiple second terminals changes, the new first terminal may flexibly realize group calling of the multiple second terminals through the above procedure.

It is understood that, although the above embodiments all take AMR-WB voice format and AMR-NB voice format as examples, the data transmission method provided by the present application is illustrated and described. However, it can be understood by those skilled in the art that, when the terminals support AMR-WB speech formats with different speech transmission rates (that is, support different speech formats), or when the terminals support AMR-WB speech formats with multiple speech transmission rates (that is, support multiple speech formats), the method can also be used to implement transmission of speech service data between the terminals, and the implementation principle and technical effect are similar, and are not described herein again.

Those of ordinary skill in the art will understand that: all or a portion of the steps of implementing the above-described method embodiments may be performed by hardware associated with program instructions. The program may be stored in a computer-readable storage medium. When executed, the program performs steps comprising the method embodiments described above; and the aforementioned storage medium includes: various media that can store program codes, such as ROM, RAM, magnetic or optical disks.
