  • Message barring system and method thereof
    Patent number: 7242673
    Abstract: A system and method for short message (SM) barring. A storage device stores a service configuration record comprising a telephone number, a first parameter and a second parameter. The first parameter indicates whether the telephone number allows incoming short message service (SMS) in a first mobile network, and the second parameter indicates whether the telephone number allows short message transmission via a second mobile network. A process unit receives a SM transmission request with a destination telephone number and an SM, acquires both the first parameter and the second parameter corresponding to the destination telephone number from the service configuration record, and transmits an error message if both the first parameter and the second parameter are negative.
