Abstract-Due to the worldwide deployment of Long Term Evolution (LTE), the fourth-generation (4G) mobile cellular networking technology, Voice over LTE (VoLTE) [2] has been also well developed in past few years. It exploits packet-switched network to provide call services instead of the traditional circuit- switched telephony. Similar to the Voice over IP (VoIP), VoLTE adopts Session Initiation Protocol (SIP) to achieve some control functions. Therefore, it means attack techniques against the SIP will also be effective against VoLTE devices. In this paper, we propose a novel device-side SIP-aware detecting system against two kinds of SIP attacks, SIP message flooding attack and malformed SIP message attack. To detect the message flooding attack, we set threshold for the traffic of SIP message received from VoLTE interface within one minute. And for the malformed message attack, we provide the structure and formalization rules of SIP messages to detect malformed SIP messages by utilizing ontology descriptions. This paper presents the design and implementation of this detecting system. The simulation test shows that this system will improve the security level of VoLTE service in real applications.
