Based on the characteristics of suddenness, complexity, dynamics and lack of information of navigation accidents, UAV technology has been organically integrated with China′s navigation accident emergency rescue system, becoming a research hotspot of maritime emergency communication. The user-centered UAV base station group network breaks the traditional base-centered architecture, and selects the set of potential service sites for each user to build a dynamic base station group, so that users can make full use of the diversified gain of potential service sites within the base station group and the cooperation gain between potential service sites. In this paper, a user-centered base station group networking scheme for UAV is proposed, and the user initial access scheme suitable for ship formation scenario is designed and its performance is simulated and evaluated.
