Claim:
1. A method performed by a system of one or more computers, the method comprising: routing, at a telecommunications signaling computer system for routing telecommunications signaling messages in a core network of a telecommunications signaling network, a first call from a calling party to user equipment (UE) of a subscriber; receiving, at the telecommunications signaling computer system, a message from the UE indicating that the subscriber has flagged the first call as a nuisance call; storing, in a subscriber-level nuisance call database, an association between a calling party identifier for the calling party and a subscriber identifier for the subscriber; in response to a second call from the calling party to the subscriber, blocking, at the telecommunications signaling computer system, the second call using the association between the calling party identifier and the subscriber identifier in the subscriber-level nuisance call database; supplying the calling party identifier to a communications analytics computer system that stores, as a result of executing a nuisance call analytics routine using the calling party identifier, the calling party identifier in a network-level nuisance call database, wherein supplying the calling party identifier to the communications analytics computer system comprises supplying the subscriber identifier to the communications analytics computer system so that the communications analytics computer system determines to store the calling party identifier in the network-level nuisance call database based on both a count of a number of subscribers flagging calls from the calling party as nuisance calls and a positive result from executing a nuisance call pattern matching routine; and blocking a plurality of calls from the calling party to a plurality of other subscribers using the network-level nuisance call database.
