Embodiment 1
[0053] Such as image 3 As shown, it is a flow chart of an embodiment of the present invention to realize that a simulated user calls a SIP broadband user in the IMS domain, and it is that the above-mentioned pulse charging method of the present invention provides a pulse charging signal to UE after ringing and before answering by AS. In addition, other network elements are also required to provide support for the scene processing.
[0054] For the sake of simplicity, it is assumed that there is only one AS between the two terminals, and the relevant CSCF network elements are replaced by two CSCF entities CSCF1 (that is, the CSCF on the calling side) and CSCF2 (that is, the CSCF on the called side). The basic call steps are as follows:
[0055] Step 1-5: UE1 picks up the phone to initiate a call, AGCF initiates a session initial request INVITE to CSCF1, CSCF1 inquires and learns the AS to which the pulse charging user belongs, triggers the call to this AS, and AS routes the ca...
Embodiment 2
[0064] Such as Figure 4 As shown, it is a flow chart of another embodiment of the present invention to realize that a simulated user calls a SIP broadband user in the IMS domain, and it is an implementation of the above-mentioned pulse charging method of the present invention that sends a pulse charging signal to the UE after the response is provided by the AS , and require other network elements to also provide support for the scene processing.
[0065] For the sake of simplicity, it is assumed that there is only one AS between the two terminals, and the relevant CSCF units are replaced by two CSCF entities CSCF1 (that is, the CSCF on the calling side) and CSCF2 (that is, the CSCF on the called side). The basic call steps are as follows:
[0066] Step 1-5: UE1 goes off-hook to initiate a call, AGCF initiates a session initial request INVITE to CSCF1, CSCF1 inquires and learns that the user belongs to the pulse charging user and the AS to which it belongs, triggers this call ...
