Reduction in network congestion
View Patent ↗A system, method and non-transitory computer readable storage medium comprising instructions that when read by a processor perform receiving a telephony connection request, determining a purported sender telephony number from the telephony connection request, determining additional request information from the telephony connection request, accessing an information source using the purported sender telephony number to determine source information regarding the sender, comparing the source information with the additional request information, based on the comparison, and determining whether the purported sender telephony number is incorrect.
1. A method, comprising:
receiving a telephony connection request;
obtaining a purported sender telephony number from the telephony connection request;
obtaining general request information from the telephony connection request;
accessing an alternate information source that is different than the telephony connection request using the purported sender telephony number, to obtain sender confirmation information regarding the purported sender of the received telephony connection request;
comparing the general request information with the sender confirmation information;
based on the comparison, determining whether the actual sender of the telephony connection request is different than the purported sender of the telephony connection request;
in the case the actual sender of the telephony connection request is determined to be the same as the purported sender of the telephony connection request, allowing the telephony connection request; and
in the case the actual sender of the telephony connection request is determined to be different than the purported sender of the telephony connection request, denying the telephony connection request.
2. The method of claim 1 , wherein the general request information comprises routing information in the telephony connection request.
3. The method of claim 2 , wherein the routing information includes an operating carrier number.
4. The method of claim 1 , wherein the sender confirmation information comprises routing information known to be associated with the purported sender telephony number.
5. The method of claim 4 , wherein:
comparing the general request information with the sender confirmation information comprises comparing the routing information in the telephony connection request with the routing information known to be associated with the purported sender telephony number; and
based on the comparison, determining whether the actual sender of the telephony connection request is different than the purported sender of the telephony connection request.
6. The method of claim 1 , wherein determining whether the actual sender of the telephony connection request is different than the purported sender of the telephony connection request includes determining that the identity of the purported sender has been spoofed.
7. The method of claim 1 , further comprising sending a reply in response to the telephony connection request when forwarding the telephony connection request to an intended recipient would result in a system response.
8. The method of claim 7 , wherein the reply differs from the system response.
9. A non-transitory computer readable storage medium comprising instructions that when read by a processor perform:
receiving a telephony connection request;
obtaining a purported sender telephony number from the telephony connection request;
obtaining general request information from the telephony connection request;
accessing an alternate information source that is different than the telephony connection request using the purported sender telephony number, to obtain sender confirmation information regarding the purported sender of the received telephony connection request;
comparing the general request information with the sender confirmation information;
based on the comparison, determining whether the actual sender of the telephony connection request is different than the purported sender of the telephony connection request;
in the case the actual sender of the telephony connection request is determined to be the same as the purported sender of the telephony connection request, allowing the telephony connection request; and
in the case the actual sender of the telephony connection request is determined to be different than the purported sender of the telephony connection request, denying the telephony connection request.
10. The non-transitory computer readable storage medium of claim 9 , comprising further instructions that when read by a processor perform sending a reply in response to the telephony connection request in the case forwarding the telephony connection request to an intended recipient would result in a system response.
11. The non-transitory computer readable storage medium of claim 9 , wherein the general request information comprises routing information in the telephony connection request.
12. The non-transitory computer readable storage medium of claim 11 , wherein the routing information includes an operating carrier number.
13. The non-transitory computer readable storage medium of claim 9 , wherein the sender confirmation information comprises routing information known to be associated with the purported sender telephony number.
14. The non-transitory computer readable storage medium of claim 13 , wherein:
comparing the general request information with the sender confirmation information comprises comparing the routing information in the telephony connection request with the routing information known to be associated with the purported sender telephony number; and
based on the comparison, determining whether the actual sender of the telephony connection request is different than the purported sender of the telephony connection request.
15. The non-transitory computer readable storage medium of claim 9 , wherein the reply differs from the system response.
16. The non-transitory computer readable storage medium of claim 9 , wherein determining whether the actual sender of the telephony connection request is different than the purported sender of the telephony connection request includes determining that the identity of the purported sender has been spoofed.
17. A system, comprising:
a processor; and
memory;
wherein the processor and the memory are communicably coupled to one another;
wherein the processor:
receives a telephony connection request;
obtains a purported sender telephony number from the telephony connection request;
obtains general request information from the telephony connection request;
accesses an alternate information source that is different than the telephony connection request using the purported sender telephony number, to obtain sender confirmation information regarding the purported sender of the received telephony connection request;
compares the general request information with the sender confirmation information;
based on the comparison, determines whether the actual sender of the telephony connection request is different than the purported sender of the telephony connection request;
in the case the actual sender of the telephony connection request is determined to be the same as the purported sender of the telephony connection request, allowing the telephony connection request; and
in the case the actual sender of the telephony connection request is determined to be different than the purported sender of the telephony connection request, denies the telephony connection request.
18. The system of claim 17 , wherein the general request information comprises route information in the telephony connection request.
