Providing network service information in a system including wide- and narrow-area wireless communication systems |
摘要 |
<p>The present invention provides a network service information providing system which allows users to readily know a location and radio transmission parameters for connecting to a narrow-area wireless communications system in a system which contains a mixture of wide-area wireless communications systems and narrow-area wireless communications systems and to set up a new narrow-area wireless communications system which can provide higher communications services without causing degradation in existing communications services in the environment where different wireless communications systems coexist. The user knows his/her own location through a wide-area wireless communications system and sends the location of a narrow-area wireless communications system which he/she wants to connect to, wireless transmission parameters, and other requirements to a wireless area information server. The wireless area information server possesses wireless transmission parameters of narrow-area wireless communications systems and the locations of base stations which provide narrow-area wireless communications services. Upon receiving the requirements from the user, the wireless area information server informs the user of the service area of the narrow-area wireless communications system nearest to the user via the wide-area wireless communications system. <IMAGE></p> |
