Purpose of this paper is to present a spectrum efficient Joint Radio Resource Management (JRRM) scheme between heterogeneous Radio Access Technologies (RATs) operating in a same location. Given future reconfigurable terminals capabilities, the vertical handover (VHO) between RATs is a promising approach to optimise resources sharing and enhance current wireless access networks performance. The novel scheme described in this paper considers hybrid metrics combining both individual user and overall system metrics to maximize the VHO success probability in the access and on going communication phases while minimizing the impact on the hosting RAT performance. In this paper, the JRRM scheme is accurately described for two RATs and can also be extended for more than two.
