When the narrow band is interconnected and intercommunicated through the gateway, only the audio media types are converted, and the gain is not adjusted. Because the difference of the playing gains of the broadband and narrowband terminals is too large, the volume of the broadband terminal playing the audio from the narrowband terminal is too small, and the volume of the narrowband terminal playing the audio from the broadband terminal is too large.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of 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 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.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a first embodiment of a communication method between different networks according to the present application. The method comprises the following steps:
s101: the gateway receives voice data from the first network terminal while performing a voice communication service in the first network terminal and the second network.
In a specific implementation scenario, a first network terminal performing a voice communication service in a first network and a second network terminal performing a voice communication service in a second network perform the voice communication service through a gateway. The gateway is used for realizing connection between the first network and the second network. The first network terminal sends the voice data which needs to be sent to the second network terminal to the gateway, and the gateway receives the voice data.
In this implementation scenario, the first network and the second network are different networks, for example, the first network is a narrowband network, and the second network is a broadband network. In this implementation scenario, the narrowband network is any one of PDT (Police Digital Trunking), DMR (Digital Mobile Radio), or TETRA (terrestrial trunked Radio). In other implementation scenarios, the network may be different types in the same network, for example, the first network and the second network are both narrowband networks, the first network is a PDT (Police Digital Trunking) network, and the second network is a DMR (Digital Mobile Radio) network.
S102: and performing gain adjustment on the voice data according to the required audio gain relation between the first network terminal and the second network terminal.
In a specific implementation scenario, after receiving voice data sent by a first network terminal, a gateway determines a multiple of gain adjustment according to an audio gain relationship between an audio gain value required by the first network terminal and an audio gain value required by a second network terminal, and performs gain adjustment on the audio data according to the multiple of gain adjustment.
Suppose D1The maximum amplitude A of the audio of the first network terminal is the preset audio gain value required by the first network terminal1Is A1＝10D1/20. Assuming that D2 is a pre-stored audio gain value required by the second network terminal, the maximum amplitude A of the audio of the second network terminal2Is A2＝10D2/20. The gain adjustment is then a multiple of
Figure BDA0002081327030000041
Or A2/A1Thus, therefore, it is
Figure BDA0002081327030000042
In this implementation scenario, the second network is a broadband network, and the first network is a narrowband network. The audio gain value of the first network terminal may be preset in the gateway, and the audio gain value of the second network terminal may be obtained from the second network terminal in advance and stored in the gateway in advance. For example, it may be sent to the gateway in advance by the second network terminal, specifically. Or when the second network terminal registers to the network, the second network terminal sends registration information to the gateway, wherein the registration information comprises the audio gain value required by the second network terminal. And the gateway stores the audio gain value after receiving the audio gain value required by the second network terminal and sent by the second network terminal.
In the field of this implementationIn the scene, the second network is a broadband network, and the gain of the audio data is amplified according to the gain adjustment multiple, namely, the gain of the audio data is amplified
Figure BDA0002081327030000043
And (4) doubling. In other implementations, the second network is a narrowband network and the gain of the audio data is reduced by the gain adjustment factor, i.e., the gain of the audio data is reduced
Figure BDA0002081327030000044
And (4) doubling.
S103: and sending the voice data after gain adjustment to the second network terminal.
In a specific implementation scenario, the gateway sends the voice data after the gain adjustment to the second network terminal, so that the second network terminal can directly play the voice data after receiving the voice data after the gain adjustment, without the need for the user to adjust the play volume of the second network terminal.
As can be seen from the above description, in this embodiment, the gateway performs gain adjustment on the received voice data sent by the first network terminal according to the required audio gain relationship between the first network terminal and the second network terminal, and sends the voice data after gain adjustment to the second network terminal, so that the second network terminal can directly play the voice data after receiving the voice data after gain adjustment, and the user does not need to adjust the play volume of the second network terminal.
Referring to fig. 2, fig. 2 is a flowchart illustrating a communication method between different networks according to a second embodiment of the present invention. The method comprises the following steps:
s201: the gateway receives a registration message from the second network terminal, wherein the registration message comprises an audio gain value required by the second network terminal and/or a media type required by the second network terminal.
In a specific implementation scenario, a first network terminal performing a voice communication service in a first network and a second network terminal performing a voice communication service in a second network perform the voice communication service through a gateway. In this implementation scenario, the first network is a narrowband network and the second network is a broadband network, or in other implementation scenarios, the first network may be a broadband network and the second network may be a narrowband network. The audio gain value and the media type required by the first network terminal are different from those required by the second network terminal.
In this implementation scenario, the narrowband network is any one of PDT (Police Digital Trunking), DMR (Digital Mobile Radio), or TETRA (terrestrial trunked Radio)
And the second network terminal sends a registration message to the gateway when accessing the network, wherein the registration message comprises the audio gain value and the media type required by the second network terminal. In other implementation scenarios, it may be that one of the audio gain value and the media type required by the first network terminal is different from that of the second network terminal, and then only the content related to the different item may be included in the registration information. For example, if the audio gain value required by the first network terminal is different from the audio gain value required by the second network terminal, only the audio gain value required by the second network terminal may be included in the registration information.
S202: and saving the audio gain value required by the second network terminal and/or the media type required by the second network terminal.
In a specific implementation scenario, the audio gain value and the media type required by the first network terminal are different from those required by the second network terminal. Therefore, before the gateway sends the received audio data to the second network terminal, the gateway needs to perform the processing of converting the media type and adjusting the gain value on the audio data. The gateway saves the received audio gain value and media type required by the second network termination before processing. The method is used for calculating the needed gain adjustment multiple and media adjustment type by combining the preset audio gain value and media type required by the first network terminal.
S203: when the first network terminal and the second network terminal perform voice communication service, the gateway receives voice data from the first network terminal.
In this embodiment, this step is substantially similar to step S101 in the first embodiment of the communication method between different networks provided by the present invention, and details are not repeated here.
S204: and carrying out media type conversion on the audio data according to the pre-stored media type required by the second network terminal.
In a specific implementation scenario, the gateway converts the audio data into a G711 media type according to a pre-stored media type required by the second network terminal, and then converts the audio data of the G711 media type into the media type required by the second network terminal. Because the media type with the G711 as an intermediate conversion can effectively reduce the loss and error code caused in the media type conversion. In other implementation scenarios, the audio data may also be directly converted into a media type required by the second network terminal.
S205: and performing gain adjustment on the voice data after media type conversion according to the required audio gain relation between the first network terminal and the second network terminal.
In this embodiment, this step is substantially similar to step S102 in the first embodiment of the communication method between different networks provided by the present invention, and step S102 in the first embodiment of the communication method between different networks provided by the present invention performs gain adjustment on voice data, while in this embodiment, the gain adjustment is performed on voice data after media type conversion, and specific methods and principles are substantially the same, and are not described herein again.
In other implementation scenarios, step S205 may be executed first, and then step S204 is executed, or step S204 and step S205 may be executed simultaneously.
S206: and sending the voice data subjected to media type conversion and gain adjustment to the second network terminal.
In this embodiment, this step is substantially similar to step S103 in the first embodiment of the communication method between different networks provided by the present invention, and is not described here again.
As can be seen from the above description, in this embodiment, the gateway receives and stores the audio gain value and/or the media type required by the second network terminal in advance, performs media type conversion and gain adjustment on the received voice data sent by the first network terminal in combination with the preset audio gain value and/or the preset media type required by the first network terminal, and sends the voice data subjected to the media type conversion and the gain adjustment to the second network terminal, so that the second network terminal can directly play the voice data after receiving the voice data without adjusting the volume.

s301: the second network terminal sends a cluster registration message to the second network core network.
In a specific implementation scenario, the second network terminal is connected to the gateway through a second network core network. And after the second network terminal is started up and finishes the attachment process, establishing connection with the second core network. The second network terminal sends a TRUNKING registration REQUEST message (trunk REGISTER REQUEST message) to the second network core network to initiate the TRUNKING registration procedure. Wherein the group registration request message carries an audio gain required by the second network terminal and/or a media type required by the second network terminal.
S302: the second network core network sends a registration message to the gateway.
In a specific implementation scenario, the second network core network obtains the audio gain required by the second network terminal and/or the media type required by the second network terminal from a ringing REGISTER REQUEST message sent by the second network terminal, generates a registration message (REGISTER message) carrying the audio gain required by the second network terminal and/or the media type required by the second network terminal, and sends the REGISTER message to the gateway.

S305: the second network core network sends the cluster registration receiving message to the second network terminal.
In a specific implementation scenario, the second network core network receives the 200OK message sent by the gateway, confirms that the gateway has successfully received the registration message, and stores the audio gain required by the second network terminal and/or the media type required by the second network terminal, and then sends a TRUNKING registration grant message (trunk REGISTER ACCEPT message) to the second network terminal. The second network terminal is informed that the cluster registration has been granted.
S306: the second network terminal sends a cluster registration completion message to the second network core network.
In a specific implementation scenario, the second network terminal sends a TRUNKING registration COMPLETE message (trunk REGISTER COMPLETE message) to the second network core network to notify the second network core network that the TRUNKING registration is COMPLETE, and the second network terminal joins the TRUNKING communication.
S307: the first network core network sends a session request message to the gateway.
In a specific implementation scenario, a first network terminal initiates a single call to a second network terminal, and therefore, the first network terminal sends a request message to a first network core network, and the first network core network sends a session request message (INVITE message) to a gateway in response to the request message. The INVITE message may be a psip (program and system information Protocol) message or a sip (Session Initiation Protocol) message.
S308: the gateway sends the session request message to the second network core network.

In a specific implementation scenario, the second network core network receives the CALL CONNECT message, confirms that the second network terminal agrees with the session request, generates a 200OK message, and sends the 200OK message to the gateway. The 200OK message may be a sip message.
S312: the gateway sends a 200OK message to the first network core network.
In a specific implementation scenario, the gateway forwards the received 200OK message, which may be a psip message or a sip message, to the first network core network.
S313: the first network core network sends an ACK message to the gateway.
In a specific implementation scenario, the first network core network sends an ACK message to the gateway to inform the gateway 200 that the OK message has been successfully received. The ACK message may be a psip message or a sip message.

S316: the first network core network sends voice data to the gateway.
In a specific implementation scenario, a user of a first network terminal starts speaking, and the first network terminal obtains speech data of the user speaking and sends the speech data to a first network core network. After receiving the voice data, the first network core network generates an RTP (Real-time Transport) message according to the voice data, and sends the RTP message to the gateway.
S317: the gateway performs media type conversion and/or gain adjustment on the received voice data.
In a specific implementation scenario, the gateway converts the audio data into a G711 media type according to a pre-stored media type required by the second network terminal, and then converts the audio data of the G711 media type into the media type required by the second network terminal. Because the media type with the G711 as an intermediate conversion can effectively reduce the loss and error code caused in the media type conversion. In other implementation scenarios, the audio data may also be directly converted into a media type required by the second network terminal.
After media type conversion, the gateway determines the multiple of gain adjustment for the received voice data according to the audio gain relation between the audio gain value required by the first network terminal and the audio gain value required by the second network terminal, and performs gain adjustment for the audio data according to the multiple of gain adjustment. Wherein, the audio gain value required by the first network terminal can be preset in the gateway.

Assuming that D2 is a pre-stored audio gain value required by the second network terminal, the maximum amplitude A of the audio of the second network terminal2Is A2＝10D2/20. The gain adjustment is then a multiple of

Or A2/A1Thus, therefore, it is
Figure BDA0002081327030000102

Because the media type with the G711 as an intermediate conversion can effectively reduce the loss and error code caused in the media type conversion. In other implementation scenarios, the audio data may also be directly converted into a media type required by the first network terminal.
After media type conversion, the gateway determines the multiple of gain adjustment for the received voice data according to the audio gain relation between the audio gain value required by the first network terminal and the audio gain value required by the second network terminal, and performs gain adjustment for the audio data according to the multiple of gain adjustment. Wherein, the audio gain value required by the first network terminal can be preset in the gateway.

And the first network core network sends the voice data subjected to the media type conversion and the gain adjustment to the first network terminal. Therefore, the first network terminal can directly play the voice data after receiving the voice data, and a user does not need to adjust the volume of the first network terminal.
In this implementation scenario, the first network is a narrowband network and the second network is a broadband network, or in other implementation scenarios, the first network may be a broadband network and the second network may be a narrowband network. In this implementation scenario, the narrowband network is any one of PDT (Police Digital Trunking), DMR (Digital Mobile Radio), or TETRA (terrestrial trunked Radio)
