The present invention discloses a method for realizing a re-answer call, comprising: S402, the calling user that a mobile terminal belongs to calls and communicates with the called user that a fixed terminal belongs to, and a media gateway control equipment sends to a media processing equipment a detecting event of re-answer signal; S404, the fixed network in which the fixed terminal resides when detecting the called user hangs up, sends to the media processing equipment a message that the called user hangs up, and the media processing equipment sends the message that the called user hangs up to the media gateway control equipment; S406, after receiving the message that the called user hangs up, the media gateway control equipment does not release the call immediately, but in order to wait for the hang-up of the calling user, initiates a delay detecting process during which when receiving a re-answer message from the media processing equipment, the media gateway control equipment cancels the delay detecting process and makes the calling user to communicate with the called user. The present invention realizes a re-answer call in which TDM link and a channel associated signaling protocol are employed between the fixed network and the media processing equipment of NGN network to carry out a voice call. |
