Processing method of time delay calling

The invention discloses a processing method of time delay calling. The processing method is based on a system. The system comprises a plurality of signaling information detecting and processing devices connected with a relevant number seven signaling link or an IP signaling link and a time delay processing platform connected with a signaling network. The processing method comprises the following steps. A signaling information screening step is performed, the signaling information detecting and processing devices detect and process signaling information which runs through, and relevant information which is called out is screened on the time delay platform through the signaling network. A calling time delay processing step is performed. The time delay processing platform sends called initial address information to a called end office in a time delay mode based on preset service rules and authentication on calling number information, and meanwhile, sends back verified information to a calling end office immediately. The processing method of time delay calling can be performed by being independent of existing communication networks and can avoid upgrading of a node switching device. The function of providing a blacklist and a whitelist is achieved, and in addition, unreasonable calling is effectively limited in a calling process through a time delay continuous method.
