Embodiment 1
[0048] In this embodiment, it is assumed that the call initiated by the user does not include intelligent services, but only common services. The process flow of the method of Embodiment 1 is shown in Figure 1, specifically as follows:
[0049] Step 101: When the office switch receives a call initiated by the local office user, it generates a Call ID for the call initiated by the current user, and fills the Call ID in the call message body sent to the next-hop office switch. The call message body may be of ISUP or SIP-T type according to the actual situation. And, the call message body added with the Call ID is sent to the next-hop office switch.
[0050] Wherein, the Call ID can be defined according to the structure definition of the network call reference field (Network call reference) information unit defined in the ITU-T Q.763 protocol standard, and added to the call message body.
[0051] When the originating office needs to generate a bill, record the generated Call ID...
Embodiment 2
[0069] Fig. 3 is a flow chart of the method of this embodiment. In this embodiment, it is assumed that both the SSP and the SCP need to generate smart bills.
[0070] Step 301: When the office switch receives a call initiated by a local office user or an incoming call through a relay, and finds that the received call needs to trigger an intelligent service, the office switch triggers the SCP through the SSP to provide the user with an intelligent service.
[0071] Step 302: While providing the intelligent service to the user, the SCP allocates a unique identifier Call ID for the intelligent service, and issues the Call ID to the office switch and the SSP through the SSP.
[0072] Here, the way for the SCP to issue the Call ID can be: the SCP adds a private field in the INAP message, records the currently assigned Call ID in the added private field, sends the INAP message carrying the Call ID to the SSP, and then the SSP Send it to the office switch.
[0073] Step 303: when t...
