A method of controlling storage of short messages in short message service centers of a mobile network supporting number portability, the short messages having been sent from originating subscribers identified by corresponding subscriber numbers belonging to the mobile network, the method comprising the steps of:
- receiving a short message from an originating subscriber in a serving exchange;
- forwarding the short message from the serving exchange toward an interworking mobile switching center for storage in a short message service center;
- interposing a number portability logical entity between the serving exchange and the interworking mobile switching center, the number portability logical entity being adapted to carry out the steps of:
- (a) receiving an indication of a short message sent from an originating subscriber identified by a predetermined subscriber number and extracting the predetermined subscriber number;
- (b) determining from a number portability database whether the originating subscriber is authorized to store a short message in a short message service center;
- and
- (c) if the originating subscriber is authorized, relaying the short message to the interworking mobile switching center for storage in the short message service center, and if the originating subscriber is not authorized, rejecting the short message toward the serving exchange.
Apparatus for controlling storage of short messages in short message service centers of a mobile network supporting number portability, the short messages having been sent from originating subscribers identified by corresponding subscriber numbers belonging to the mobile network, the apparatus comprising at least one number portability logical entity that includes:
- a number portability database of information specifying, for at least one subscriber identified by a corresponding subscriber number, whether the at least one subscriber is authorized to store a short message in a short message service center;
- means for analyzing Mobile Application Part operations, including means for receiving an indication of a short message sent from an originating subscriber identified by a predetermined subscriber number, means for determining whether the originating subscriber identified by the predetermined subscriber number is authorized to store a short message in a short message service center, and means for rejecting the short message if the originating subscriber identified by the predetermined subscriber number is determined not to be so authorized;
- and
- means for relaying the short message towards an interworking mobile switching center for further storage in a short message service center before delivery of the short message.
