Abstract

Methods, systems, and computer program products are disclosed for preventing the delivery of unwanted SMS messages, such as those containing unsolicited commercial messages or spam, in a communications network. More particularly, SMS messages are intercepted prior to delivery and at least a portion of the SMS message content is encapsulated within an electronic mail (e-mail) message. The e-mail message is communicated to an e-mail spam filtering resource in a data network, where spam screening/filtering algorithms are applied. The e-mail message is discarded at the e-mail spam filtering resource if the message fails spam screening. Alternatively, or in addition, the results of the spam screening may be returned with the original message for another network node to process accordingly. In any case, if the message passes spam screening, the original SMS message that is associated with the e-mail message may be delivered to/toward the intended message recipient.

Claims

1. A method for screening short message service (SMS) messages, the method comprising:

(a) receiving, at a network element separate from an electronic mail (e-mail)-based spam filter, an SMS message that includes a short message payload;

(b) creating, at the network element, an e-mail message that includes at least a portion of the SMS message; and

(c) transmitting the e-mail message to the e-mail-based spam filter, wherein the e-mail-based spam filter determines whether the at least a portion of the SMS message contained in the e-mail message includes spam content, and wherein the method further comprises, in response to the determination by the e-mail-based spam filter that the at least a portion of the SMS message contained in the e-mail message does not include spam content, notifying the network element and routing the SMS message from the network element to its destination.

2. The method of claim 1 wherein receiving an SMS message includes receiving the SMS message at a network routing node.

3. The method of claim 1 wherein receiving an SMS message includes receiving the SMS message at a short message service center.

4. The method of claim 1 wherein creating an e-mail message that includes at least a portion of the SMS message includes creating an e-mail message that includes the SMS payload.

5. The method of claim 4 wherein creating an e-mail message includes storing the SMS payload information in a subject field of the e-mail message.

6. The method of claim 4 wherein creating an e-mail message includes storing the SMS payload body portion of the e-mail message.

7. The method of claim 1 wherein creating an e-mail message includes creating an e-mail message that is addressed to an e-mail address associated with the network element that creates the e-mail message.

8. The method of claim 1 comprising:

(a) receiving a message from the e-mail-based spam filter indicating that the SMS message does not include spam content;

(b) using at least a portion of the SMS message information contained in the e-mail message to reconstruct the SMS message; and

(c) wherein routing the SMS message to its intended destination includes routing the reconstructed SMS message to its intended destination.

9. A method for screening short message service (SMS) messages, the method comprising:

(a) receiving, at a network element separate from an electronic mail (e-mail)-based spam filter, an SMS message that includes short message payload information;

(b) storing the SMS message in a message buffer of the network element;

(c) creating, at the network element, an email message that includes at least a portion of the SMS message;

(d) transmitting the e-mail message to the e-mail-based spam filter, wherein the e-mail-based spam filter determines whether the at least a portion of the SMS message contained in the e-mail message includes spam content, and in response to the determination by the e-mail-based spam filter that the at least a portion of the SMS message contained in the e-mail message does include spam content, discarding the e-mail message; and

(e) at the network element, determining whether the e-mail message has been discarded, and, in response to determining that the e-mail message has been discarded, discarding the SMS message stored in the message buffer.

10. The method of claim 9 wherein creating an e-mail message includes creating an e-mail message that includes an identifier associated with a message processing module storing the SMS message.

11. The method of claim 9 wherein creating an e-mail message includes creating an e-mail message that includes an identifier associated with a storage location of the SMS message in the message buffer.

12. The method of claim 9 wherein creating an e-mail message includes creating an e-mail message addressed to an e-mail address associated with the network element that created the e-mail message.

13. The method of claim 9 comprising:

(a) receiving an e-mail message from the e-mail-based spam filter;

(b) using information contained in the e-mail message to extract the SMS message from the message buffer; and

(c) routing the SMS message.

14. A method for screening message service messages, the method comprising:

(a) receiving, at a network element separate from an electronic (e-mail)-based spam filter, a message service message that includes a payload;

(b) creating, at the network element, an email message that includes at least a portion of the message service message; and

(c) transmitting the e-mail message to the e-mail-based spam filter, wherein the e-mail-based spam filter determines whether the at least a portion of the message service message contained in the e-mail message includes spam content, and wherein the method further comprises, in response to the determination by the e-mail-based spam filter that the at least a portion of the message service message contained in the e-mail message does not include spam content, notifying the network element and routing the message service message from the network element to its destination.

15. The method of claim 14 wherein receiving a message service message includes receiving a multimedia message service (MMS) message.
