This article investigates new techniques for the dimensioning and the eﬀective exploitation of radio resources in integrated terrestrial-cellular and satellite systems. A dynamically conﬁgurable radio resource management policy is proposed. Its main feature is the diﬀerentiated handling of user mobile calls, based on the type of service (voice, symmetric data, asymmetric data), the nature of the call (originating or handoﬀ call) and the user mobility class (pedestrian or vehicular). The output of the study is particularly useful to support the design of next-generation wireless systems, which are based on a hierarchical cell structure where diﬀerent cell types (e.g., macrocell and microcell) operate together with an overlapping satellite coverage.
