Method and system for associating content with map zoom function

Various methods, systems and apparatus for displaying content associated with a point-of-interest (“POI”) in a digital mapping system, are disclosed. One such method may include detecting a change in the zoom level of an electronic map displayed on a computing device, determining if the new zoom-level is at a pre-determined zoom level (e.g. at maximum zoom), identifying a POI on the map, retrieving content associated with the POI (“POI content”) and displaying the POI content. The method may further include detecting a change in the zoom, or pan, of the digital map while POI content is displayed, and removing the POI content in response. One apparatus, according to aspects of the present invention, may include means of detecting a change in the zoom level in a digital map displayed through an application (e.g. a web browser, an application on web-enabled cellular phones, etc., displaying a map generated by a service such as Google Maps®, Yahoo! Maps®, Windows Live Search Maps®, MapQuest®, etc.) on a computing device (e.g. personal computer, workstation, thin client, PDA, cellular phone/smart phone, GPS device, etc.) means of identifying a POI at the pre-determined zoom level, means of obtaining content associated with the POI, and means of displaying the POI content. POI content may be retrieved from a database (e.g. internet-based database); or, in an alternate embodiment, gathered by crawling websites associated with the POI. In one embodiment, POI content may be displayed as an image (e.g. a PNG file, GIF, Flash® component, etc.) superimposed on the digital map (e.g. as an overlay object on the map image.) In alternate embodiments, POI content may replace the digital map and may contain links to other content.

Method and system for handover in cellular wireless using route programming and training processes

A method and system for managing handover where a database that receives location information about a moving object includes information regarding which base station is used in a current radio link connection and which base stations were used from historic radio link connections. Using the base station radio link history of the object and an electronic map, a processor coupled to the memory of the database selects which physical path the moving object is using. Upon matching the object's path with a history of path routes on the list, the processor will apply an optimized handoff sequence to the moving object. The optimized route can be derived from an algorithm that processes previous historical data from moving objects traveling on the same route. Methods of providing the location of moving objects via location sensors may be used to provide the database with higher resolution information about a moving object's location on an electronic map and allow further enhancement of the handoff optimization. Generally, location data is used to quickly determine which route the moving object is using and more quickly assign an optimized handoff sequence. Historical data along known routes can include time and spatial information to be processed by the routing algorithm. The database may reside in a central location or within each moving object or a combination of both.
