Call processing in an intelligent network when the traffic between SSP and SCP is congested

摘要

A method for ensuring intelligent user to talk, comprising: the service switching point (SSP) judges whether there has occurred abnormal instance between itself and the service control point (SCP), if yes, then the SSP will turn off all the intelligent triggers within it that are concerned during this call, and perform normal call connecting process, otherwise, the SSP will perform the existing intelligent call connecting process. The present invention can still ensure the intelligent user to talk normally when there occurs abnormal instance between SSP and SCP. Additionally, in the present invention, the SSP further judges whether performing call connecting process according to the corresponding relation between the preset intelligent user identifier, the abnormal reason, and whether performing call connecting processing while it determines there has occurred abnormal instance between itself and the SCP, but rather than performing call connecting process blindly on all intelligent users, thus can ensure that it would not add too much traffic load to the SSP.
