Information associated with a communication is gathered at a switching point during the routing process to determine subscriber metric information associated with an active service identifier. The information relates to the originator of the communication and the target. The information is compared to a provider database to determine a carrier originally associated with the active service identifier. The information is then compared to a porting database to determine if the active service identifier was ported, and if so, to which carrier the active service identifier was ported. A determination can then be made regarding which carrier is associated with the active service identifier. The data may be aggregated for a large amount of switched communications, representing a large amount of active service identifiers for a given market. Thus, a number of subscribers for a given carrier in a given market may be determined. |
