  • So-called channel-dependent signaling is an inter-exchange signaling, that is, transmitting voice information and corresponding signaling on the same path, and the control signal required for the voice channel is from the voice channel itself or There is a fixed connection signaling path to pass.
  • the channel signaling consists of two parts: line signaling and register signaling: Line signaling mainly transmits the contents of occupation, response, and disconnection of some related trunks; the signaling of the register is passed through the two exchanges.
  • FIG. 1 is a basic interaction flow of inter-office signaling in a public switched telephone network (PSTN), where 1, 2, 9 and 10 are line signaling, and 3, 4, 5, 6 7, 7 and 8 are register signaling.
  • PSTN public switched telephone network
  • SS Softswitch
  • MG media gateway
  • the event is used to define a series of softswitch SSs that require the associated signaling of the media gateway MG to detect, and the signal is used to define that the series media gateway detects that it needs to report soft.
  • FIG. 2 illustrates the implementation of an associated basic call flow in an NGN network.
  • the SS controls the MG to implement the associated signaling interaction through the H.248 protocol.
  • the caller control release mode In the PSTN, there are three ways to release the call after the call is completed: the caller control release mode, the called control release mode, and the mutual control release mode.
  • the caller control release mode if the caller hangs up first, the caller is idle and the called party hears the busy tone. If the called party hangs up first, if the called party picks up the phone within a certain time range, an off-hook signal will be generated to the calling party, and the calling party and the called party re-enter the call.
  • FIG. 3 is a flow chart showing the implementation of the off-hook line signal in the caller control release mode after a call in the PSTN.
  • the inter-path connection in the PSTN does not require the intervention of the media gateway control protocol H.248, and can be completed by an off-hook line signaling.
  • the ITU-T Recommendation H.248.28 of the Media Gateway Control Protocol H.248 specification provides a specification for implementing inter-office signaling through the H.248 protocol between the softswitch SS and the media gateway MG.
  • the off-hook line signaling of the associated signaling is not supported between the softswitch SS and the media gateway MG.
  • the object of the present invention is to solve the problem that the prior art does not support the interaction of the off-hook line signaling between the softswitch SS and the media gateway MG.
  • the main idea of the present invention is to define an off-hook event and signal in the relevant protocol, so that the calling user and the called user establish a call through the associated signaling, and after the call, if the called party is on-hook, the soft The exchange notification informs the gateway where the controlled party is located to detect the off-hook event. If the callee's user picks up the phone again within a certain period of time, the gateway of the controlled user's gateway sends a softswitch report to the off-hook event, and the softswitch receives the call.
