Geographic Filtering in Telecommunications Terminals

The patent applies local quality by making the information reception characteristic of each terminal location-dependent. Terminals automatically determine their geographic location and compare it with the geographic relevance indicators in broadcast messages, receiving only information that is locally pertinent. This resolves the contradiction by ensuring information completeness for each location while reducing the overall information volume processed by each terminal.

The patent segments the broadcast information space into geographically-defined regions. Each message is associated with geographic relevance indicators that define specific areas of pertinence. Terminals segment their information processing by evaluating whether their current location falls within these geographic regions, thereby receiving only the subset of information relevant to their location rather than processing all broadcast information.

The patent implements self-service by enabling terminals to autonomously perform geographic filtering without requiring complex centralized control. Each terminal independently determines its own location, retrieves geographic relevance indicators from broadcast messages, and autonomously decides whether to process or discard each message based on location matching. This approach improves information relevance while minimizing system complexity by distributing the filtering intelligence to individual terminals.

The patent applies preliminary action by pre-associating geographic relevance indicators with information during the broadcasting process. Rather than performing complex filtering operations in real-time, the system prepares the filtering criteria in advance by embedding geographic region definitions with each message, allowing terminals to perform simple location-based matching operations.
