Abstract: Systems and methods for filtering emergency broadcast messages. One embodiment is User Equipment (UE) that store rules for filtering emergency broadcast messages. The UE receives an emergency broadcast message over a paging channel of a mobile network, identifies a class indicator assigned to the emergency broadcast message, selects one of the rules based on the class indicator assigned to the emergency broadcast message, and determines whether the emergency broadcast message is authorized for presentation on the UE based on the rule. The UE then ignores the emergency broadcast message responsive to a determination that the emergency broadcast message is not authorized for presentation.

Abstract: Disclosed is a method for delivering emergent event notifications to a user's Mobile Device. Map and Calendar applications are polled with correlations made between map locations and event information. Geo-Fence Boundaries are established for map locations which are inherited by their associated events. Penetration of a Geo-Fence Boundary by a Mobile Device running the Mobile Application triggers a search for events that are associated with the established Geo-Fence Boundary. Filtered Notifications of event options of interest to the user are transmitted to the Mobile Device based on pre-established and dynamic variables and whether the user can arrive at the event while it is underway. Upon selection of an event by the user, the Mobile Device provides route and navigation guidance to the selected location.

Abstract: A unified message delivery between multiple devices is disclosed. Sending messages through a local communications link, such as but not limited to at least one of a Bluetooth connection and a peer-to-peer WiFi connection, can lead to faster transmission times and reduced server load. When the local communications link is unavailable or not suitable, the messages can be sent through a network and a push server. In some examples, messages can be sent through both the local communications link and through the network and the push server. Duplicates of a received message can be avoided by utilizing indicators. In some examples, one or more devices can include queue(s) to ensure ordered delivery of a plurality of messages when a local communications link and network connection become unavailable.
