A system and method for automatically detecting Anti-Steering of Roaming activity is disclosed. This method can be used by a monitoring system on a home network that continuously monitors all international MAP signaling with a visited network. Anti-Steering of Roaming is detected by estimating a number of roaming subscribers of different types, including a number of unique active roamers, a number of unique steered roamers, and a number of unique anti-steered roamers. The numbers of subscribers of the different types, either alone or in combination, are compared to threshold values. If the numbers exceed the threshold value, then the monitoring system alerts the home network that a visited network may be using Anti-Steering of Roaming technology. |
