发明名称 Transmission of location and directional information associated with mobile communication devices
摘要 A method and arrangement for providing location information of a called mobile communication device to a calling party is implemented through a mobile device locator platform disposed in the communication network. A mobile device subscriber to the location service initiates a process where the location of his mobile device is updated on a regular basis and the location information stored in a database on the platform. When a call is placed to his subscribed device, the location information is transmitted to the calling party prior to setting up the call to the called device, allowing the calling party to determine whether or not to proceed with the call, as well as eliminating the need to ask the common question "where are you?" when placing a call to a mobile device.
