Next Generation Public Safety Communication (PSC) is a crucial topic for research community worldwide. There is a strong need of research towards Public Safety user requirements, such as mobility and security support in a system architecture able to interconnect heterogeneous access technologies belonging to different agencies and jurisdiction. In this work, a combination of Proxy Mobile IPv6 (PMIPv6) and Host Identity Protocol (HIP) is proposed, in order to beneficiate of a complete macro and micro-mobility management protocol with the added values of intra and inter-technologies handover and multi-homing features for a heterogeneous and secure network with minimum impact on Public Safety mobile user terminals. This new approach is applied to our proposed ad-hoc satellite and wireless mesh architecture for emergency mobile communications and a complete description of the PMIPv6-HIP mobility management phases is provided.
