Abstract: In this paper, basic mechanisms of interoperability between long-term evolution (LTE) as 4G cellular system and mobile WIMAX networks as 4G wireless are introduced. Two cost-based mechanisms are investigated to represent two interoperability functions: initial network selection (INS) and inter-network handover (INH). Simplified approaches that ease the evaluation of related cost functions (CFs) are proposed. The necessary assumptions for the implementation of a joint LTE-WIMAX system level simulator platform, through a real coexistence scenario, are proposed. Numerical results show a considerable enhancement in terms of selected performance metrics such as blocking and dropping probabilities. Weight values readjustments are also tested to highlight the critical key factors affecting interoperability mechanisms.
