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