Cost effective notifications with delivery guarantee

摘要

A first notification indicating a change on an account of a mobile station is generated and sent to an account holder of the mobile station via a first delivery procedure, when the change on the account of the mobile station occurs. The first notification is sent to the account holder only if a destination for the first delivery procedure has not changed for at least a predetermined period. A second notification of the change on the account of the mobile station is sent to the account holder via a second delivery procedure, if the first notification is not successfully sent to the account holder. Additional notifications of the change on the account of the mobile station may be sent to the account holder via respective different delivery procedures consecutively until any of the notification is successfully sent to the account holder. The first, the second and the various delivery procedures are among a Short Message Service (SMS) message, an Enhance Messaging Service (EMS), a Multimedia Messaging Service (MMS), an email, a fax, a voice call and a letter. Order of the delivery procedures to be sent may be determined based on cost for sending the notifications.
