  • Patent number: 6169897
    Abstract: A mobile communications system which provides a mobile subscriber with local information related to the area where his/her mobile terminal is located. A link list page is compiled in a URL list server by collecting the URLs of various home pages containing local information, and a local representative URL is assigned to the compiled link list page. A URL retrieving unit receives an area identification signal from a radio base station, and retrieves the local representative URL associated with the received area identification signal. A representative URL transmission unit then transmits the local representative URL retrieved by the URL retrieving unit to the URL list server, thus making access to the link list page stored therein. A list transmission unit, disposed in the URL list server, retrieves the link list page that corresponds to the local representative URL received from the representative URL transmission unit, and it returns the retrieved local URL list to the mobile terminal.
