LOCATION DEPENDENT DYNAMIC SECONDARY PHONE BOOK

摘要

A mobile communication device is equipped with a dynamic local directory into which contact information from a local telephone directory may be downloaded on a temporary basis. The local telephone directory resides on a local communication network and may be accessed by the mobile communication device. The downloaded data is purged automatically after a preset time delay expires or the location is abandoned. The dynamic local telephone directory on the mobile communication device is continuously changing depending on the location.
