1. A method comprising:
- periodically scanning an access router that serves a target user equipment to detect a state change of the target user equipment by inspecting one or more of a DHCP log, authentication log, authorizing log, and accounting log of the access router;
collecting an address assignment record of the target user equipment via the access router;
passing the address assignment record to a discovery server, wherein the discovery server correlates the address assignment record with one or more data sources, the data sources including authentication, authorization, and accounting (AAA) nodes, operations support systems (OSS), and business support systems (BSS);
identifying a location of the target user equipment at the discovery server based on the address assignment record of the target user equipment;
replicating a packet flow of the target user equipment as seen by the access router; and
monitoring the packet flow to determine quality of service issues experienced by the target user equipment.

Abstract
A system and method for discovering user equipment in a network is disclosed. According to one embodiment, a discovery proxy periodically scans an access router that serves a target user equipment and collects an address assignment record of the target user equipment via the access router. The discovery proxy passes the address assignment record to a discovery server, and the discovery server identifies a location of the target user equipment based on the address assignment record of the target user equipment.

15. A system comprising:
-
a user equipment; an access router that is configured to bind with the user equipment; a discovery proxy configured to periodically scan the access router and collect an address assignment record of the user equipment via the access router, to detect a state change of a target user equipment by inspecting one or more of a DHCP log, authentication log, authorizing log, and accounting log of the access router; a discovery server that is configured to receive the address assignment record from the discovery proxy and identify a location of the user equipment based on the address assignment record of the target user equipment, wherein the discovery server correlates the address assignment record with one or more data sources, the data sources including authentication, authorization, and accounting (AAA) nodes, operations support systems (OSS), and business support systems (BSS); and a packet analysis server that receives a replicated packet flow of the target user equipment and monitors the replicated packet flow to determine quality of service issues experienced by the target user equipment. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
