Automatic detection method for choking mass calls to telecommunications network addresses

摘要

The method involves writing the call numbers of each address to a memory (2) when a communications unit within the network experiences unsuccessful calls. The contents of the memory are read out at defined intervals and sorted (3) according to address The frequency of successful calls per address is computed (3). The calls to each address for which the computed frequency exceeds a first defined value (4) are limited (5). The limitation is lifted (7) when the frequency of successful calls falls below a second defined level (6) which is lower than the first level.
