Abstract: System for providing alert-based communication services for which corresponding alert conditions to be met by mobile stations are defined. The system includes an alert engine capable of firing alerts associated with the alert-based communication services if location data regarding the mobile stations is indicative of the mobile stations meeting the alert conditions corresponding to the alert-based communication services. A requirements engine determines an expected earliest future time at which at least one alert condition is capable of being met by a particular mobile station and outputs a data element indicative of a requirement to obtain updated location data about the particular mobile station in advance of the expected earliest future time. A scheduler receives expiry times data and processes the expiry times data for determining an order for servicing the location requests.

Abstract: In one aspect, a method and system are provided for preprocessing a weighted planar undirected graph and representing the results of the preprocessing so as to facilitate subsequent approximate distance queries. A representation can be constructed so that an approximate distance from one node to another can be computed quickly. Also, the representation in one embodiment stores information for computing distances in a relatively compact format, thus reducing memory requirements. In another aspect, a method and system are provided which use the representation for rapid computation of distances.
