SUMMARY This paper describes the simulated system performances of the enhanced spread spectrum ALOHA (E‐SSA) random access scheme in a realistic mobile satellite multibeam scenario operating in S‐band. The E‐SSA random access scheme has been selected for supporting messaging services in the ETSI S‐band Mobile Interactive Multimedia (S‐MIM) standard. Finally, the operation and the performance of E‐SSA is elaborated in the context of a terrestrial gap‐filler component complementing the satellite coverage in densely populated areas. It is shown that the terrestrial network is able to off‐load traffic from the satellite component while ensuring continuity of service in areas that cannot be covered by a satellite only system.
