Abstract
Selective acceptance of short messages enables a cellular subscriber to predetermine which short message will actually be delivered to the subscriber'"'"'s mobile station. Using an Unstructured Supplementary Service Data (USSD) transmission, the subscriber determines which selection criteria will be used and then builds in the network Home Location Register (HLR) a list of originating entities from which short messages will either be accepted or rejected. A screening application resident on the HLR then determines the identity of the entity associated with any request for short message routing information and causes the short message to be delivered or deleted according to the input provided by the subscriber. A confirmation message is returned to the originating entity indicating delivery or the reason for failure.
