To provide a propagation environment notification method in radio communication allowing a user to easily understand radio propagation environment information. When receiving a service start command C1 from a user terminal 100, a server 102 transfers software for clients to the user terminal 100 (C2). The user terminal 100 starts the transferred software for clients, and a user condition inputting process P2 is carried out to collect user specific information and radio base station information and transfer the same to the server 102 (C3). When receiving the information, the server 102 starts a distribution information generating process P1 for generating radio propagation environment information based on the information, and the generated information is transferred to the user terminal 100 (C4), and is converted into a format convenient for the user by the software for clients transferred on the user terminal 100, and displayed on the user terminal 100 (P3).
