Claim:
1. A method comprising: receiving, by a data-processing system, i) a first set of subscriber data having a parameter, wherein the first set of subscriber data is associated with a predetermined first mobile station, and ii) an identifier of the first mobile station, wherein the identifier of the first mobile station has a value; generating, by the data-processing system, a second set of subscriber data comprising a first modified parameter, wherein the generating of the second set is based on the value of the received identifier of the first mobile station, and wherein the value of the first modified parameter restricts an end-user service to a second mobile station; transmitting, by the data-processing system, the second set of subscriber data to a Visitor Location Register (VLR) serving the second mobile station; generating, by the data-processing system, a second modified parameter whose value differs from that of a received parameter in the received first set of subscriber data, the received parameter corresponding to the second modified parameter, wherein the generating of the second modified parameter is based on the value of the received identifier of the first mobile station, and wherein the value of the second modified parameter restricts an end-user service to the first mobile station, relative to the value of the corresponding received parameter in the first set; and transmitting, by the data-processing system, the second modified parameter to a Visitor Location Register (VLR) serving a location area in which the first mobile station is present.
