delivering an SMS message from said first subscriber in said first mobile operator network to said subscriber of said second mobile operator network;

intercepting the SMS message inbound delivery attempt in said second mobile operator network before delivery of said SMS message;

replacing a mobile network location address of said second subscriber in an HLR query response with the network location address of a smart services control node;

routing said intercepted SMS message delivery attempt via the smart services control node in second operator mobile network;

examining said message delivery attempt for possible invocation of a smart service to said SMS message; and

invoking said smart services for said SMS message destined to said subscriber of said second mobile operator network in response to said examination.

3. A method of managing SMS messages as claimed in claim 1 wherein the step of intercepting includes intercepting an inbound HLR query associated with said message delivery attempt.

4. A method of managing SMS messages as claimed in claim 3 wherein the step of intercepting includes intercepting an inbound HLR query associated with said message delivery attempt and examining said intercepted HLR query such that said HLR query provides an indication that a smart service needs to be applied to said SMS message and route the SMS message to the smart services control node.

5. A method of managing SMS messages as claimed in claim 4 wherein said indication from the HLR Query is associated with one or more of the following:

a SMS service, a specific subscriber directory number (MSISDN), a directory number in the HLR Query matches a specific number prefix, a specific SMSC identified by its PLMN network address, a foreign SMSC network address.

6. A method of managing SMS messages as claimed in claim 4, further comprising the step of replacing a mobile network location address of said second subscriber with the network location address of the smart services control node such that the first mobile network operator routes said SMS message via said smart services control node.

7. A method of managing SMS messages as claimed in claim 1 wherein the step of intercepting said message delivery attempt is based on a condition that said query originated from said SMSC or another mobile network.

8. A method of managing SMS messages as claimed in claim 4, further comprising the step of routing said SMS message from said smart services control node to said real location address wherein said SMS message is routed to said real network location address from an address stored in said smart services control node previously obtained from said HLR query response.

9. A method of managing SMS messages as claimed in claim 1, further comprising the step of terminating said SMS message delivery attempt in the said smart services control node when the said smart service requires that the said SMS message is not delivered to the said subscriber of the said second operator network.

10. A method of managing SMS messages as claimed in claim 1 further comprising the step of terminating said SMS message delivery attempt when said condition of said intercepted delivery attempt indicates in said second operator network that said SMS message originates from a barred originating entity belonging to another network.

11. A method of managing SMS messages as claimed in claim 1, further comprising the step of triggering the execution of smart service logic associated with said smart services SMS control node in response to condition based on the content of said SMS message.

12. A method of managing SMS messages as claimed in claim 1, further comprising the step of triggering the execution of smart service logic associated with said smart services SMS control node in response to condition based on the content of said SMS message and wherein said trigger condition is a meta tag signal or attribute associated with said SMS message.

13. A method of managing SMS messages as claimed in claim 1, further comprising the step of generating a unique identifier for said SMS message at said smart services SMS control node.

14. A method of managing SMS messages as claimed in claim 1, further comprising the step of generating a unique identifier for said SMS message at said smart services SMS control node, wherein said unique identifier is generated from one or more of the following SMS message parameters:

Originating Address, Destination Address, message fragment number, SMSC address or SMS Centre timestamp.

15. A method of managing SMS messages as claimed in claim 1, further comprising the step of generating a unique identifier for said SMS message at said smart services SMS control node;

storing said unique identifier in a storage memory of said smart services control node.

16. A method of managing SMS messages as claimed in claim 13, further comprising the step of comparing the generated unique identifier with unique identifiers for each SMS message delivery attempt processed by said smart services SMS node for detecting a subsequent attempt of an SMS message from a remote SMSC after the first delivery attempt.

17. A method of managing SMS messages as claimed in claim 13, further comprising the step of comparing the generated unique identifier with unique identifiers for each SMS message delivery attempt processed by said smart services SMS node for detecting a subsequent attempt of an SMS message from a remote SMSC after the first delivery attempt, wherein only unique identifiers are stored in said storage memory for retry SMS delivery attempts for comparison and wherein said retry SMS delivery attempt is routed onwards by the smart services control node to the real network location address of the said subscriber after said comparison.

18. A method of managing SMS messages as claimed in claim 13, further comprising the step of comparing the generated unique identifier with unique identifiers for each SMS message delivery attempt processed by said smart services SMS node for detecting a subsequent attempt of an SMS message from a remote SMSC after the first delivery attempt, wherein only unique identifiers are stored in said storage memory for retry SMS delivery attempts for comparison and wherein said retry SMS delivery attempt is routed onwards by the smart services control node to the real network location address of the said subscriber after said comparison and said onward routing is conditionally based on a service indicator associated with the smart services control node.
