The package module, for being packaged to encoded broadband voice data, and the lattice for the AMR-WB data packets that disguise oneself as
Formula, by mutually encoded ultra wide band voice data is packaged in the same time, and the format for the AMR-WB data packets that disguise oneself as；
The mark module, for marking broadband voice data packet and ultra wide band voice number mutually in the same time in a manner of timestamp
According to packet；
The sending module, for marked broadband voice data packet and ultra wide band VoP to be sent to opposite end end
End.
7. a kind of device for realizing ultra wide band voice intercommunication, which is characterized in that the device is located in terminal, including：Negotiation module,
Receive matching module and decoding playing module；Wherein,
The negotiation module carries out code encoding/decoding mode negotiation for local module with to end module, and the distant terminal is to support
The terminal of AMR-WB code encoding/decoding modes, the local terminal are the terminal for supporting EVS code encoding/decoding modes；
The reception matching module, for receiving the broadband voice data packet and ultra wide band voice data that the distant terminal is sent
Packet, and the data packet of two kinds of phases in the same time is matched；The broadband voice data are by the distant terminal using the first speed
Rate carries out package after AMR-WB codings, and the ultra wide band voice data is used by the distant terminal and assisted with the local terminal
Package after the coding mode of quotient encodes, the sum of the first rate and the second rate are not higher than AMR-WB standard speeds；
The decoding playing module, for executing decoding play operation to broadband voice data and ultra wide band voice data；
Wherein, the decoding playing module includes：Decoder module and playing module；
The decoder module is decoded ultra wide band voice data, institute for carrying out AMR-WB decodings to broadband voice data
It is the decoding process negotiated with the distant terminal to state to the decoding process that ultra wide band voice data is decoded；
The playing module, for by mutually in the same time broadband voice data and ultra wide band voice data splice, and play.
8. a kind of terminal, which is characterized in that the terminal includes：The dress of realization ultra wide band voice intercommunication described in claim 6
It sets.
9. a kind of terminal, which is characterized in that the terminal includes：The dress of realization ultra wide band voice intercommunication described in claim 7
It sets.
