Increasing marine activities taking place within the exclusive economic zone (EEZ) have made broadband maritime communications very attractive in recent years. In this paper, a coordinated satellite and terrestrial (II-CST) architecture is presented to enable real-time and broadband Internet access within the EEZ. Further, a voyage-based resource allocation scheme is proposed to dynamically adapt the system resource consumption corresponding with the user load. We make switching plans for shipborne base stations (S-BSs) considering the proportion of blocked users and changes in user distribution to recover broadband access and reduce inter-cell interference at sea, and take the sailing position of accessed users as a constraint to cooperatively adjust the downlink power of S-BSs. Simulation results under real ship data of China's Yellow Sea show that under the II-CST architecture, our resource allocation scheme can effectively improve the signal to interference noise ratio (SINR) of users, reduce the number of handover-related link failures, and reduce the power consumption of S-BSs.
