The allocation of limited resources such as links, servers, and agents to support as many as emer gency call responses as possible while maintaining rea sonable quality of service is a principal requirement in public safety networks. It is difficult to handle the high est priority emergency call responses for a congested period with a limited number of dedicated incoming links from commercial networks. Therefore, in this pa per, we present the adaptive scheme based on a different call conversation time for an achieving efficient resource scheduling during a congested period without investing extra resources. The proposed adaptive scheduling ap proach improves accuracy of the network performance with the dynamic call holding time approach.Abstract-Resource allocation, Call holding time, Public safety net.
