Abstract
A method for bearing voice data includes: a) a calling MSCe and the called MSCe determining that a calling MS and a called MS support the same voice coding and decoding type and that a call is a point-to-point call; b) the calling MSCe and the called MSCe sending Bearer Update Requests to the calling BSC and the called BSC, respectively; and c) the calling BSC and the called BSC setting up a voice bearer path between the calling MS and the called MS according to the requests from the MSCes. As a result, transparent transmission of voice data in a MGW is avoided so that transmission delay can be reduced and additional loading of the MGW can be avoided.
Claims20
A method for bearing voice data, comprising:
- determining, by a calling Mobile Switching Center Emulation (MSCe) and a called MSCe, that a calling Mobile Station (MS) and a called MS support a same voice coding and decoding type and that a call between the calling MS and the called MS is a point-to-point call;
- sending by, the calling MSCe and the called MSCe, a Bearer Update Request to a calling BSC (Base Station Controller)and a called BSC respectively;
- and
- setting up, by the calling BSC and the called BSC, a voice bearer path between the calling MS and the called MS according to the Bearer Update Request from the MSCes.
A system for bearing voice data, comprising:
- a calling BSC;
- a calling MSCe;
- a called BSC;
- and
- a called MSCe, wherein:
- the calling MSCe and the called MSCe are configured to judge whether a calling MS and a called MS support the same voice coding and decoding type and whether a call is a point-to-point call, and also to send Bearer Update Requests to the calling BSC and the called BSC, respectively;
- and
- the calling BSC and the called BSC are configured to set up a voice bearer path between the calling MS and called MS according to the Bearer Update Requests from the calling MSCe and the called MSCe.
A MSCe, comprising a judgment module and a communication module, wherein:
- the judgment module is configured to judge whether a calling MS and a called MS support the same voice coding and decoding type and whether a call is a point-to-point call, and to notify the communication module of a judgment result;
- and
- the communication module is configured to send a Bearer Update Request to the BSC according to the notification from the judgment module.
