Wherein, if among the step a500, media controller indication Media Processor increases a mixer end points, and the sign of not carrying the mixer end points in indication, then after the step a500, can also comprise before the step a501:
Media Processor distributes a sign for the mixer end points that increases, and returns the indication response message that carries this sign to media controller;
After then media controller is received this indication response message, set up and preserve the corresponding relation of mixer end points and this sign.
Further, Media Processor can adopt transmission tissue (the InternationalTelecommunication Union-Transmission of International Telecommunications Union, ITU-T) Q.1950 the mode of the transmission feature bag (Bearer characteristics package) of middle definition comes to be mixer end points allocation identification, realize such as characteristic value by expansion bearer network attribute (BNC), as shown in the table:
| BNC characteristic value (Characteristics value) | Q.765.5 binary coding (binary encoding) | Text code (Text encoding) |
| Mixer | 0x01FF | Mix |
In the present embodiment, adopt H.248 agreement to carry out alternately between media controller and the Media Processor.
Media controller can place indication the H.248 message that can carry beared information of agreement, sends to Media Processor, such as: add (ADD) message, revise (MODIFY) message, move (MOVE) message or the like; Media Processor all needs to return an indication response message to media controller after receiving Indication message, if Add Request message, then Media Processor returns an interpolation response message (Add Resp) to media controller.
Shown in Fig. 5 B, the embodiment of the invention separation architecture method of circulation increase subscriber endpoints down comprises the following steps:
When step b500, media controller are set up session connection at needs, the instruction that increases a mixer end points is placed interpolation message, send to Media Processor.
