Efficient communications are crucial for disaster response and recovery. However, most current public safety Land Mobile Radio (LMR) networks only provide narrowband voice service with limited support of low-speed data services due to the packet delay and loss and less resource utilization. So high resource utilization techniques are needed. The Session Initiation Protocol (SIP) and a joint radio resource management framework is a current technology to support the interoperability between cellular and LMR networks. SIP is seamless handoff scheme.
