Embodiment 1

[0077] In this embodiment, the information sent by the MGC includes: SIGNAL ID. In this embodiment, some special sounds are defined through configuration on the MGW and need to be played in a sound mixing mode to achieve sound mixing.

[0078] Fig. 4 is a schematic diagram of the process of realizing sound mixing in an embodiment of the present invention, and the process includes:

[0079] Step 401: MGC sends a message including SIGNAL ID to MGW.

[0080] In step 401, the MGC sends a message including the SIGNAL ID to the MGW.

[0081] In step 401, the MGC sends a message containing the SIGNAL ID to the MGW in many cases. Usually, the MGC sends the message to the MGW when it determines that the user needs to hear the voice corresponding to the SIGNAL ID.

[0082] Step 402-Step 404: MGW judges whether the received SIGNAL ID is the SIGNAL ID corresponding to the pre-configured audio playback source that needs to be mixed. Mixing is not required.

[0083] The method of pre-co...

Embodiment 2

[0087] In this embodiment, the information sent by the MGC includes: SIGNAL ID, and an instruction to play and mix audio.

[0088] Fig. 5 is a schematic diagram of the process of realizing sound mixing in an embodiment of the present invention, and the process includes:

[0089] Step 501: MGC sends to MGW a message including SIGNAL ID and play mixing instruction.

[0090] In step 501, the MGC sends a message including a SIGNAL ID and an instruction to play the audio mix to the MGW.

[0091] In step 501, the MGC will send a message containing the SIGNAL ID to the MGW in many cases. Usually, the MGC sends the message to the MGW when it determines that the user needs to hear the voice corresponding to the SIGNAL ID.

[0092] As for the audio mixing indication, usually for some user-customized audio sources that need to be audio mixed, it is indicated by extending the parameters of whether the SIGNAL ID corresponding to the audio audio source needs to be audio mixed in the H248 i...

Abstract

The method comprises: a) media gateway controller (MGC) sends a message including signal ID to media gateway (MGW); b) according to received message, MGW makes sound mixing for the voice and call speech corresponding to the signal ID. The invention also reveals a apparatus thereof comprising: multi user units, a control unit for receiving the message including signal ID from outside and sending sound mixing control message to the playback unit; and a playback unit for receiving the sound mixing control message from the control unit and playing back audio data to at least one user unit; after the user unit receives the audio data from the playback unit and audio data from other user units, it sends it to the external user's resources.

Description

technical field [0001] The invention relates to a technology for playing audio mixing, in particular to a method and device for realizing audio mixing in a separated core network. Background technique [0002] In the separated core network of the third generation mobile communication system version 4 (R4), the bearer is completed by the media gateway (MGW), and the control is completed by the media gateway controller (MGC). Among them, the mobile MGC controls the allocation of MGW through the H248 protocol bearer resources or transfer corresponding call bearer control signaling. The interface between the MGC and the MGW is called the H248 interface or the Mc interface. [0003] Figure 1 is a schematic diagram of the process of realizing ordinary communication in the MGC and MGW, and the process includes: [0004] Step 101: The MGC sends a message (ADD T1) to add a calling side packet endpoint to the MGW. [0005] Step 102: The MGC sends to the MGW a message (ADD T2) for a...
