A study on fast MMD session control methods in 3G mobile communications

In recent years, IMS/MMD architectures have been gaining importance as the key technologies for the Next Generation Network, which is standardized by ITU-T. These architectures utilize SIP for session management and, in particular, MMD utilizes Mobile IP for mobility support of mobile nodes. When both protocols are used at the same time, the problem of inefficiency and delay in the MMD session controls for handover arises due to the fact that they work independently. In this paper, we propose fast session control methods that involve cooperation between these protocols. Further, we implement and evaluate our proposed methods, and show the improvements in session control time.
