Patent ID: 7602753

Claim:
An apparatus for tracing GTP resource, comprising: a call tracing unit for receiving a command of a call tracing from an operator through MMI and performing the call tracing; a call tracing DB for storing call-tracing data currently processed; a GTP-U tracing unit for tracing a GTP-U message and reporting the GTP-U message to the call tracing unit; a SGSN interface unit for receiving the GTP-U message outputted from the SGSN; and an internet interface unit for transmitting the GTP-U message routed at the GTP-U tracing unit to an internet network, wherein the GTP-U tracing unit comprises: a call tracing interface unit for processing a GTP-U tracing function message requested from the call tracing unit and transmitting a result of the GTP-U data tracing; a TEID converter for converting the IMSI or IP received from the call tracing interface unit to a TEID; a trace load controller for minimizing a load of an exchanger, the load generated from the GTP-U data tracing function; a GTP-U traffic detector for detecting a traffic for tracing the GTP-U between the SGSN interface unit and the internet interface unit; and a GTP-U tracing DB for storing the IMSI information for mapping the TEID and information for the GTP-U tracing.
