Abstract :
A variety of wireless interfaces are available to access Internet content in a heterogeneous network composed by technologies with limited QoS abilities. Performance increasing solutions become economic in specific parts of the network architecture, as the network sizes and the clients´ numbers increase. SIP is used to locate the called party to check that the capabilities of the calling and called parties are consistent and to establish and control the connection. In this paper, we propose an addition to the SIP header/message compression methodology to improve the network QoS by implementations of SIP protocol quality options. We also deal with related SIP security issues regarding practicality and realization possibilities. This paper would like to highlight that security vulnerabilities, open problems may exist using the SIP protocol in usual cases of the practical usage.
