Next Generation Networks (NGNs) are aiming to integrate different access technologies for the accessibility of heterogeneous platform under the control of IP protocol. In such a complex environment, the availability of high data rates, high bandwidth, security and end-to-end QoS are major challenges. In this paper, cross-layer localized mobility management based on Session Initiation Protocol (SIP) and Hierarchical MIPv6 (HMIPv6) is proposed to support the providence of the end-to-end QoS; network and session mobility, reduce latency and proper bandwidth management. The proposed scheme handles the mobility locally to minimize latency.
