Neighboring Cell List Definition Using Mobility Paths

The patent applies local quality by differentiating the treatment of neighboring cells based on their specific characteristics. Instead of uniformly treating all topologically adjacent cells equally, the method assigns different weights and probabilities to cells based on their geometric relationship with the current cell and their presence in mobility paths. This allows the system to prioritize cells that are more likely to be involved in hand-overs while de-emphasizing less likely candidates, thereby improving hand-over success rate without simply reducing the number of cells considered.

The patent applies partial action by selectively including only the most relevant neighboring cells in the NBR set rather than comprehensively including all topologically adjacent cells. The method calculates a probability value for each neighboring cell based on its geometric relationship with the current cell and its occurrence in mobility paths, then includes only cells above a threshold probability. This partial approach reduces the NBR set size to a manageable level, thereby shortening measurement campaign duration and improving productivity while maintaining sufficient coverage for effective hand-overs.

The patent applies the intermediary principle by introducing mobility path data as a mediating factor between the network planning system and the hand-over decision-making process. Instead of directly analyzing complex user movement patterns, the system uses pre-processed mobility path information (stored as vectors describing sequences of cells) as an intermediary resource. This intermediary data structure simplifies the planning process by providing ready-to-use statistical information about user movement patterns, which can be directly queried to determine cell probabilities without requiring complex real-time analysis of actual user trajectories.
