Claims:WE CLAIM:
1. A method for effective and reliable lawful interception content transmission across one or more networks, the method comprising:
determining, by a session continuity server controller , one or more defects in lawful interception content transmission associated with a user session, wherein the one or more defects comprise one or more degraded network conditions and degraded lawful interception content;
executing, by the session continuity server controller, one or more corrective measures based on the one or more defects in lawful interception content transmission; and
determining, by the session continuity server controller, stability of the lawful interception content transmission post one or more corrective measures for effective and reliable lawful interception content transmission.

2. The method of claim 1, wherein the one or more degraded network conditions are determined based on a pre-defined network condition threshold and an applicable network condition threshold.

3. The method of claim 2, wherein the applicable network condition threshold is determined based on correlation of historical congestion levels and historical processing capacity levels associated with content duplication element with historical occurrence of the one or more defects, wherein the content duplication element is a network element capable of performing content duplication.

4. The method of claim 1, wherein defective lawful inception content is determined based on a pre-defined content quality threshold, actual network path length, link availability factor, link quality factor.

5. The method of claim 4, wherein the pre-defined content quality threshold is determined based on number of headers frames, decryption time, data packet transmission delays and data packet retransmissions.

6. The method of claim 1, wherein the one or more corrective measures comprise at least one of selection of a new content duplication element, selection of a new session continuity server.

7. A session continuity server controller, the controller comprising:
a memory; and
a processor coupled to the memory storing processor executable instructions which when executed by the processor causes the processor to perform operations comprising:
determining one or more defects in lawful interception content transmission associated with a user session, wherein the one or more defects comprise one or more degraded network conditions and degraded LI content;
executing one or more corrective measures based on the one or more defects in lawful interception content transmission; and
determining stability of the lawful interception content transmission post one or more corrective measures for effective and reliable lawful interception content transmission.

8. The controller of claim 7, wherein the one or more degraded network conditions are determined based on a pre-defined network condition threshold and an applicable network condition threshold.

9. The controller of claim 8, wherein the applicable network condition threshold is determined based on correlation of historical congestion levels and historical processing capacity levels associated with content duplication element with historical occurrence of the one or more defects, wherein the content duplication element is a network element capable of performing content duplication.

10. The controller of claim 7, wherein defective lawful inception content is determined based on a pre-defined content quality threshold actual network path length, Link Availability Factor, Link Quality Factor.

11. The controller of claim 10, wherein the pre-defined content quality threshold is determined based on number of headers frames, decryption time, data packet transmission delays and data packet retransmissions.

12. The controller of claim 7, wherein the one or more corrective measures comprise at least one of selection of a new content duplication element, selection of a new session continuity server.

13. A non-transitory computer readable medium including instructions stored thereon that when processed by at least one processor causes a production surveillance device to perform operations comprising:

determining one or more defects in lawful interception content transmission associated with a user session, wherein the one or more defects comprise one or more degraded network conditions and degraded LI content;
executing one or more corrective measures based on the one or more defects in lawful interception content transmission; and
determining stability of the lawful interception content transmission post one or more corrective measures for effective and reliable lawful interception content transmission.
14. The medium of claim 13, wherein the one or more degraded network conditions are determined based on a pre-defined network condition threshold and an applicable network condition threshold.

15. The medium of claim 14, wherein the applicable network condition threshold is determined based on correlation of historical congestion levels and historical processing capacity levels associated with content duplication element with historical occurrence of the one or more defects, wherein the content duplication element is a network element capable of performing content duplication.

16. The medium of claim 13, wherein defective lawful inception content is determined based on a pre-defined content quality threshold actual network path length, link availability factor, link quality factor.

17. The medium of claim 16, wherein the pre-defined content quality threshold is determined based on number of headers frames, decryption time, data packet transmission delays and data packet retransmissions.

18. The medium of claim 13, wherein the one or more corrective measures comprise at least one of selection of a new content duplication element, selection of a new session continuity server.
