Downloading geographical data to a mobile station and displaying a map

A mobile communication network system (2) comprising a plurality of mobile stations, at least one (1) of said mobile stations comprising a geographical position localising module (3) for localising a geographical position (24c) of said mobile station (1), storage means for storing geographical related base data, and display means (4) for displaying geographical related base data as a map (24) or as a text string, wherein said geographical related base data displayed on said display means (4) has been at least partly provided by wireless transmission from said network system (2) and is limited to a pre determinable extent depending on said geographical position (24c) of said mobile station (1), where said mobile station (1) is characters by that:

• said geographical related base data displayed on said display means (4) has been at least partly provided by a Network Broadcast Station
• a check is performed by said mobile station (1) whether said geographical related base data proud or to be provided by wireless transmission is already available at said mobile station (1) and subsequently loading data in said mobile station is performed only if no corresponding data are available or if data available at said mobile station (1) are not of the latest version,
• said geographical related base data are stored at said mobile station (1) even after power-off, the amount of said stored data depending on the availability of memory capacity of said mobile station (1),
• loading of said data is done according to specific circumstances for said mobile station (1), including a travel modus and a travel speed of said mobile station (1),
• said geographical position localising module (3) is a Global Positioning System (GPS) module providing position information as geographical coordinates or a GSM/UMTS localising system for mobile stations,
• mobile station (1) itself preforms calculation of the geographical position and assistance from said network system (2) is only performed by said general broadcast information of normal operation and location dependent information to all mobile stations within a oil of said network system (2),
• said geographical position or localisation data of said mobile station (1) can be send by said mobile station (1) to others as location name strings or geographical co-ordinates by using short message service (SMS) or according to set-up during the active call set-up phase;
• the set-up specifics presentation or restriction of calling or called mobile station geographic position,
• said mobile station (1) displays a position marked out map (24), a position text string, or Local Area information data at an idle mode, i.e. at a standby mode,
• said mobile station (1) comprising calculation means for calculating travelling parameters of the travelling mobile station (1), such as speed, distance, direction or time values,
• said mobile station (1) displays on said display means (4) said travelling parameters,
• a scale of said map (24) or said geographical related base data displayed on said display means (4) depends and preferably adapts automatically to a traveling speed or a present surrounding of said mobile station (1),
• a direction to go from the location of said mobile station (1) is calculated by a navigational algorithm implemented in location finder module (31) of said mobile station (1) and said direction is indicated on said display means (4) of said mobile station (1),
• directional information based on destination information and information concerning present location of said mobile station (1) is given by said mobile station (1),
• a best possible route is provided by said mobile station (1) since the needed information is loaded per location and the traffic information can be attached to said local area information, and
• said mobile station (1) can filter and can display only such information that is relevant for said mobile station (1) according to its present location, present travel direction, present travel speed, or given destination.
