Abstract
The present invention detects whether an initial mobile number assignment is suboptimal, resulting in excessive roaming. If excessive roaming is encountered, the telematics service provider determines the effective home area of the telematics unit and assigns an appropriate replacement number to the unit. In this way, the disclosed principles allow a telematics service provider to decrease its roaming charges, and/or those of its users, and more optimally manage its mobile phone number assignments.
