Agent based protocol analyzer and protocol analyzing method for LTE system

摘要

PURPOSE: A protocol analysis apparatus for an agent based LTE(Long Term Evolution) system and method thereof are provided to grasp errors of a connected message by collecting the connected message in the LTE system. CONSTITUTION: A protocol analysis apparatus agent(100) captures an LTE message using a packet capture library. The protocol analysis apparatus agent extracts a target message from the LTE message. The protocol analysis agent transmits the target message to a protocol analysis apparatus server(200). The protocol analysis server analyzes the message transmitted from the protocol analysis apparatus agent. The protocol analysis server displays the analyzed result on the set screen. When the transmitted message is analyzed, an LTE protocol message which is defined as XML(eXtensible Markup Language) meta information is utilized.
