VALIDATION OF A FORWARD-TO-NUMBER BY A MOBILE STATION |
摘要 |
A call forwarding activation request is transmitted from a mobile station to the serving mobile switching center (MSC) over a data channel incapable of carrying voice data. However, mobile subscribers and mobile service providers would like to establish a speech connection between the mobile station and the forward-to-number to ensure that the forward-to-number has been dialed correctly and that desired parties are at the other end. Accordingly, whenever a call forwarding activation request is received by the mobile station, the mobile station itself initiates an outgoing call setup toward the forward-to-number. The connection-less signal encapsulating the activation request is transmitted to the serving MSC only after the successful completion of such call setup. After receiving the transmitted connection-less signal, the serving HLR alters the call forwarding feature status to active. |
