Abstract: The patent describes techniques for delivering content to mobile communication devices, focusing on interactions within a user community. It outlines a method where a central computing entity detects a mobile communication session, determines associated context parameters, and then delivers relevant content. This entity also stores data about user community memberships, detects actions taken by a community member related to the community, and sends notifications to other members based on these actions. The goal is to facilitate continuous interaction with user communities via mobile devices.

Plain-Language Overview of Independent Claims:

Independent Claim 1:
This claim describes a method for sending content to mobile communication devices, particularly in the context of social communities. The method involves:

1. Detecting a Communication Session: Identifying when a mobile device user is engaged in a communication, specifically when this session is with a social community website.
2. Determining Context Parameters: Figuring out the details of this communication session. This includes detecting when the mobile device user has added or edited content on the social community website.
3. Retrieving Content: Based on these determined context parameters, the social community website automatically creates a "content trigger." This trigger is set to activate specific applications (called "concurrent applications") on mobile devices belonging to other members of the same social community. These activated applications then retrieve information related to the content that the initial user added or edited.
4. Delivering Content: The retrieved content, which is relevant to the context parameters (e.g., the newly added or edited community content), is then sent to one or more of these mobile communication devices.
