A communication event processing method performed at a computer server includes: obtaining identification information and call description information from multiple different terminals about a phone number; determining whether the phone number is a nuisance phone number according to the call description information and a quantity of the terminals identifying the phone number; and sending, after receiving a query request for the phone number, a blocking instruction to a terminal initiating the query when it is determined that the phone number is a nuisance phone number, so that the terminal initiating the query blocks a communication event of the phone number. According to the present disclosure, the server can determine which phone numbers are nuisance phone numbers according to specific identification cases and the call description information, and therefore provide highly accurate processing in response to a query request of a terminal, thereby greatly improving efficiency of communication event processing.
