MOBILE VoIP SERVICE SYSTEM, METHOD OF AVOIDING DEEP PACKET INSPECTION FOR MOBILE VoIP SERVICE AND APPARATUS FOR THE SAME

摘要

The present invention relates to a mobile VoIP service system, method of avoiding deep packet inspection for mobile VoIP service, and an apparatus for the same. A signaling server includes: a variable header generating unit generating a variable header by inserting dummy data of a variable length to a header to set a call to transmit/receive a voice packet; a variable data unit generating unit generating variable data units corresponding to fixed protocol variables and formed with a tag field, a length field, and a value field; and a data sequence changing unit changing a sequence of the variable data units, and then combining the variable data unit with the variable header, generating variable binary protocol data and transmitting the variable binary protocol data to a terminal.
