Abstract

The invention of present speaks to a method and system for the prevention of unwanted wireless telecommunications which is implemented as part of a computer program product in (preferentially) the telecommunications operator'"'"'s network, which meets and/or exceeds much of current, proposed and even academically anticipated legislative (and by necessity, technical) criteria, and indeed, thereby complies with the broader body of prima facie consumer requirements associated with wireless telecommunications spam filtering. Indeed, the invention provides for a remarkably flexible and customizable advance in the art through the utilization of a progressive filtering algorithm. This algorithm offers both the subscriber and the service provider with the capability to block and/or extract potentially harmful or unsolicited SMS, MMS and other such messages on the basis of an extensive range of parameters and rules.

Claims

1. A method for filtration of unwanted wireless telecommunications comprising the steps of:

monitoring traffic associated with roaming subscribers;

said traffic carried via inter-network signaling system 7 (SS7) links;

intercepting a send-routing-information message from an originating node within said traffic;

initiating a response to said originating node so as to direct said originating node to send a short message service (SMS) associated with said send-routing-information message to an SMS spam-filter via an SMS-delivery message;

receiving said SMS at said SMS spam-filter;

determining, at said SMS spam-filter, whether said SMS constitutes an unwanted message; and

,

invoking an action for managing said SMS based on results of said determining step.

2. The method of claim 1 wherein said send-routing-information message is a Send-Routing-Information for Short-Message (“

SRI_for_SM”

) based on the Global System for Mobile Communication (“

GSM”

) or an Short Message Service Request (“

SMSREQ”

) message based on American National Standards Institute protocol 41 (“

ANSI-41”

).

3. The method of claim 1 wherein said SMS-delivery message comprises a MT_Forward_Short_Message (“

MT_FSM”

) based on GSM or a Short Message Delivery Point to Point message (“

SMDPP”

) based on ANSI-41.

4. The method of claim 1 wherein said originating node is a short message service-centre (SMS-C).

5. The method of claim 1 wherein when said SMS is determined to constitute a valid message then performing the additional step of:

providing said SMS to the SMS-C via an applicable interface.

6. The method of claim 5 wherein said applicable interface is SMPP.

7. The method of claim 1 wherein said SMS spam-filter determines that said SMS constitutes an unwanted message based on one or more of a source address, a destination address, a network element address, a protocol id/type, a data coding scheme, a keyword/content search, a service identifier, a location of an originator and/or a destination.

8. The method of claim 7 wherein said location is determined based on a location element, said location element being at least one of a gateway mobile location center (GMLC) or a mobile positioning center (MPC).

9. The method of claim 1 wherein if said SMS is determined to constitute an unwanted message then said action comprises delete, store for later viewing, and notify said originating node of a failure or successful delivery.

10. The method of claim 9 wherein said action comprises notify said originating node of successful delivery in order to prevent resubmission of said SMS.

11. The method of claim 1 wherein when said SMS is determined to constitute a valid message then performing the additional steps of:

delivering said SMS directly to an intended destination for said SMS.

12. The method of claim 11 wherein said delivering step of claim 5 comprises the steps of:

requesting a location of a serving network element from the Home Location Register respective to said destination via an SRI_for_SM or an SMSREQ message; and

,

attempting to deliver said SMS to said serving network element via an MT_FSM or SMDPP message.

13. The method of claim 12 wherein if said step of attempting to deliver fails, then further performing the step of:

providing said SMS to the SMS-C via an applicable interface.

14. The method of claim 13 wherein said applicable interface is short message peer to peer (SMPP).

15. A system for filtration of unwanted wireless telecommunications comprising:

means for monitoring traffic associated with roaming subscribers;

said traffic carried via inter-network signaling system 7 (SS7) links;

means for intercepting a send-routing-information message from an originating node within said traffic;

means for initiating a response to said originating node so as to direct said originating node to send a short message service (SMS) associated with said send-routing-information message to an SMS spam-filter via an SMS-delivery message;

means for receiving said SMS at said SMS spam-filter;

means for determining, at said SMS spam-filter, whether said SMS constitutes an unwanted message; and

,

means for invoking an action for managing said SMS based on results of said determining step.

16. The system of claim 15 wherein said send-routing-information message is a Send-Routing-Information for Short-Message (“

SRI_for_SM”

) based on the Global System for Mobile Communication (“

GSM”

) or an Short Message Service Request (“

SMSREQ”

) message based on American National Standards Institute protocol 41 (“

ANSI-41”

).

17. The system of claim 15 wherein said SMS-delivery message comprises a MT_Forward_Short_Message (“

MT_FSM”

) based on GSM or a Short Message Delivery Point to Point message (“

SMDPP”

) based on ANSI-41.

18. The system of claim 15 wherein said originating node is a short message service-centre (SMS-C).

19. The system of claim 15 further comprising a means for determining whether said originating node is barred from delivery of SMS such that said means for invoking an action will reject delivery of said SMS.

20. The system of claim 15 wherein if said SMS is determined to constitute an unwanted message then said action comprises delete, store for later viewing, and notify said originating node of a failure or successful delivery.

21. The system of claim 20 wherein said action comprises notify said originating node of successful delivery in order to prevent resubmission of said SMS.

22. The system of claim 15 wherein when said SMS is determined to constitute a valid message then performing the additional step of:

providing said SMS to the SMS-C via an applicable interface.

23. The system of claim 22 wherein said applicable interface is SMPP.

24. The system of claim 15 wherein said SMS spam-filter determines that said SMS constitutes an unwanted messages based on one or more of a source address, a destination address, a network element address, a protocol id/type, a data coding scheme, a keyword/content search, a service identifier, a location of an originator and/or a destination.

25. The system of claim 24 wherein said location is determined based on a location element, said location element being at least one of a gateway mobile location center (GMLC) or a mobile positioning center (MPC).

26. The system of claim 15 wherein said system further includes a means for delivering said SMS directly to an intended destination when said SMS is determined to constitute a valid message.

27. The system of claim 26 wherein said means for delivering comprises:

means for requesting a location of a serving network element from the Home Location Register respective to said destination via an SRI_for_SM or an SMSREQ message; and

,

means for attempting to deliver said SMS to said serving network element via an MT_FSM or SMDPP message.

28. The system of claim 27 further comprising:

means for providing said SMS to the SMS-C via an applicable interface when said means for attempting to deliver fails to effect delivery.

29. The system of claim 28 wherein said applicable interface is short message peer to peer (SMPP).

30. A monitoring element for use in a system for filtering for filtration of unwanted wireless telecommunications comprising:

means for monitoring traffic associated with roaming subscribers;

said traffic carried via inter-network signaling system 7 (SS7) links;

means for intercepting a send-routing-information message from an originating node within said traffic; and

, means for initiating a response to said originating node so as to direct said originating node to send a short message service (SMS) associated with said send-routing-information message to an SMS spam-filter via an SMS-delivery message;

said SMS spam-filter operable to receive said SMS at said SMS spam-filter; and

determine, whether said SMS constitutes an unwanted message.
