Traditional, server-oriented architectures have focused on providing location-based services by using publish-subscribe, efficient message buses, and filtering mechanisms. However, given an enterprise's unique requirements, these techniques have offered mixed results when used in an enterprise context. The present invention enables an efficient way to provide location-based services to an enterprise, as well as to integrate those location-based services into the enterprise's communications platform. A platform for supporting converged, location-based communications comprises one or more application servers such as a transactional server, a Session Initiation Protocol server, and so forth. In addition, the platform advantageously comprises an event processor for managing arriving location streams that are generated by targets being monitored. Such targets include the cell phones and WiFi handsets of the enterprise users, but can also include location data from various users arriving from multiple, fixed points such as credit card readers in stores.
