In order to facilitate the description of the present invention, the implementation of the technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

The implementation method of the present invention will be described in detail below by taking the networking of FIG. 1 as an example and combining the most widely used Megaco (Media Gateway Control Protocol) in the current NGN network.

As shown in Figure 1, when the NGN network implements conference calls, the conference resources are usually provided through the media server (MS). The participants of other conference phones pass their respective media gateways. (MG) access to the MS to implement conference calls. Control of the MS and the MG is implemented through a Media Gateway Controller (MGC).

The present invention mainly relates to the core components of two NGN networks, MGC and MG. The softswitch provides logical control, and the media access gateway implements specific functions.

In the embodiment of the present invention, a media gateway controller (MGC) controls a media gateway (MG) to implement microphone mute and volume adjustment. The user operation is very simple. Press “1#” to turn the mute function on/off during the conference call. When the conference call is connected, the mute function is disabled by default. Press “1#” to turn on the function, then press “1#” to close. . Press "2#" to increase the volume and "3#" to decrease the volume.

2 is a flow chart showing a method for providing a microphone mute function in a conference call for a general telephone terminal user according to an embodiment of the present invention. As shown in FIG. 2, the method includes the following steps:

Step S201: This process starts.

Step S202: Under the control of the MGC, the MG adds the user USER1 to a conference on the MS, and the media resource allocated to the USER1 on the MG is RTP1.

Step S203, the MGC notifies the MG to receive the number by bit;

The step of the step is as follows: After the MGC modifies the remote attribute of the RTP1 and connects to the conference resource on the MS, the MG is notified by the MODIFY (Modify) message and the report is sent one by one after receiving the number. The example signaling is as follows:

T=123456789{C=123{MF=USERl {E=987654321 {tonedet/std{tl=*}} ,

SG{}}}}

In the example signaling, the transaction ID (Transaction1D) is 123456789, the association ID (ContextlD) is 123, and the event request ID (RequestlD) is 987654321. Of course, in practical applications, it is not limited to the enumerated random values. The extension package tonedet/std{tl=*} means to receive the number by bit.

In step S204, when USER1 needs to use the mute function, press "1#", and the MG receives the number and reports it to the MGC one by one through the NOTIFY message.

Step S205, the MGC notifies the MG to change the RTP to receive only; Specifically, the MGC may notify the MG to modify the state of the RTP1 to receive only ReceiveOnly by using the MODIFY message after receiving the "1#" of the USER1. The signaling is as follows:

T=123456790{C=123 {MF=RTP1 {M{0{MO=RC }}}}}

The meaning of this signaling is to modify the state of RTP1 to receive only, where MO is Mode and RC is RecieveOnly. This signaling is also a transaction, the transaction ID is 123456790, the content of the transaction is in the context (Context) 123, the mode (MO) of RTP1 is modified to receive only (RC).

At this time, other users cannot hear the voice of USER1. It should be noted that if the MS has restrictions on the media stream and cannot be interrupted, the MGC needs to modify the state of USER1 to receive only ReceiveOnly, and the signaling is as follows:

T=123456790{C=123 {MF=USER1 {M{0{MO=RC }}}}}.

Step S206, when USER1 wants to turn off the mute function, press "1#" again, and the MG receives the number and reports it to the MGC one by one through the NOTIFY message.

Step S207, the MGC notifies the MG to change the RTP to send and receive;

Specifically, after receiving the "1#" of USER1, the MGC notifies the MG through the MODIFY message.

The state of RTP1 is modified to send and receive SendReceive (or modify the state of USER1 to SendReceive) signaling as follows:

T=123456791 {C=123 {MF=RTP1 {M{0{MO=SR }}}}}.

Step S208, the process ends.

At this time, other users can hear the sound of USER1, and if USER1 wants to use the mute function again, step S204 can be repeated.

FIG. 3 is a flow chart showing a method for providing a volume adjustment function for a general telephone user according to an embodiment of the present invention. As shown in FIG. 3, the flow includes the following steps:

Step S301: This process starts.

Step S302: Under the control of the MGC, the MG user USER1 joins a conference on the MS, and the media resource allocated to the USER1 on the MG is RTP1, tdmc/gain=0, and the call starts. Step S303: When USER1 needs to increase the volume, press "2#", and the MG receives the number and reports it to the MGC one by one through the NOTIFY message.

Step S304: After receiving the "2#" of USER1, the MGC notifies the MG to increase the gain of USER1 by 1db by using the MODIFY message, that is, tdmc/gain=l, and the signaling is as follows:

T=12345678{C=321 {MF=USER1 {M{0{tdmc/gain=l }}}}}.

Where USER1 is the user identifier. It should be noted that in the present invention, when tdmc/gain is used as a user identifier, it indicates the transmission gain of the MG with respect to the user, and when acting on the media identifier, it indicates the gain when the RTP packet is transmitted. The definition in the protocol is not clear enough. If the system considers that tdmc/gain acts on the user ID and indicates that the MG sends the RTP gain, you can modify the gain of the media packet by the MS to adjust the volume of the user.

Step S305: The MG adjusts the user gain according to the MGC signaling. If the user needs to continue to increase the volume, step S303 is repeated.

Step S306: When USER1 needs to decrease the volume, press "3#", and the MG receives the number and reports it to the MGC one by one through the NOTIFY message.

Step S307: After receiving the "3#" of USER1, the MGC informs the MG by using the MODIFY message to reduce the gain of USER1 by ldb, that is, tdmc/gain=0, and the signaling is as follows:

T=12345679{C=321 {MF=USER1 {M{O{tdmc/gain=0}} } } }.

Step S308: The MG adjusts the user gain according to the MGC signaling. If the user needs to continue to decrease the volume, step S306 may be repeated. Thereafter, the user can repeatedly adjust the volume by "2#" and "3#".

Step S309, the process ends.

It should be noted that, in the case of no conflict, the Megaco protocol in the foregoing embodiment may be controlled by a gateway having the same function as the SIP, such as SIP (Session Initiation Protocol) and MGCP (Media Gateway Control Protocol). Control Protocol) Protocol instead. For example, when using the SIP protocol, the status of the RTP media can be controlled by SDP; when using the MGCP protocol, the gain control parameter gc in the LocalConnectionOptions can be used to adjust the volume, using the Connection Mode to control Terminal The sending and receiving status of the household, etc.
