Embodiment 1
[0033] See figure 1 , the call service implementation method provided in this example specifically includes:
[0034] After detecting that the calling terminal is off-hook, the calling side end office allocates the calling subscriber circuit to the calling terminal;
[0035] The calling side end office receives the call request sent by the calling terminal, establishes a main call circuit to the called side end office according to the received call request, and initiates a main outgoing call to the called side end office;
[0036] After receiving the main outgoing call, the called terminal office allocates a called subscriber circuit for the corresponding called terminal, and feeds back a ringback response to the calling side end office;
[0037] The called end office detects that the called terminal is off-hook, and sends a call message to the calling end office;
[0038] After receiving the call message, the calling side end office establishes a backup call circuit to the ...
Embodiment 2
[0061] In order to better understand the present invention, the present invention will be further described below in conjunction with a complete call flow.
[0062] In this example, for the convenience of expression and understanding, for the calling side, define the main call circuit as the main outgoing call circuit, and the backup call circuit as the backup outgoing call circuit; for the called side, define the main call circuit as the main The call circuit is a standby incoming call circuit; in this example, the information between the calling service processing module and the called service processing module is selected to be processed through the NO.7 / NO. signaling processing module, wherein, NO.7 signaling processing The module refers to the No.7 signaling software module, and the No.1 information processing module refers to the No.1 Suilu China No.1 software module, collectively referred to as the No.7 / No.1 information processing module. Below, the present invention wi...
