Abstract
A method and apparatus for identifying an unwanted short message service (SMS) message from SMS messages received by a cellular mobile communication system, which comprises at least a history database (HB) for storing a set (H) of the messages received by the cellular mobile communication system. The method includes the steps of: measuring a difference in an information content between a SMS message (m) received by the cellular mobile communication system and the set (H) of messages stored in the history database (HB), and marking the SMS message (m) as being an unwanted SMS message if the difference that is measured is less than or equal to a predefined threshold value.
Claims20
A method of identifying an unwanted short message service (SMS) message from SMS messages received by a cellular mobile communication system, which comprises at least a history database (HB) for storing a set (H) of the messages received by the cellular mobile communication system, the method comprising the steps of:
- measuring a difference in an information content between a SMS message (m) received by the cellular mobile communication system and the set (H) of messages stored in the history database (HB), and
- marking the SMS message (m) as being an unwanted SMS message if the difference that is measured is less than or equal to a predefined threshold value.
An apparatus for identifying an unwanted short message service (SMS) message from SMS messages received by a cellular mobile communication system, the apparatus, when in use, being coupled to the cellular mobile communication system that comprises at least a history database (HB) for storing a set (H) of the messages received by the cellular mobile communication system, the apparatus comprising:
- a comparator operable to measure a difference in an information content between a SMS message (m) received by the cellular mobile communication system and the set (H) of messages stored in the history database (HB).
A cellular mobile communication system comprising:
- a plurality of cellular mobile communication devices;
- at least one database comprising a history database (HB) for storing a set (H) of the messages received by the cellular mobile communication system,
- at least one apparatus for identifying an unwanted short message service (SMS) message from SMS messages received by the cellular mobile communication system, the apparatus, when in use, being coupled to the cellular mobile communication system and comprising a comparator operable to measure a difference in an information content between a SMS message (m) received by the cellular mobile communication system and the set (H) of messages stored in the history database (HB).
A computer program storing a program readable by a computer for performing a method of identifying an unwanted short message service (SMS) message from SMS messages received by a cellular mobile communication system, which comprises at least a history database (HB) for storing a set (H) of the messages received by the cellular mobile communication system, the method comprising the steps of:
- measuring a difference in an information content between a SMS message (m) received by the cellular mobile communication system and the set (H) of messages stored in the history database (HB), and
- marking the SMS message (m) as being an unwanted SMS message if the difference that is measured is less than or equal to a predefined threshold value.
