Mobility Management Entity Path Selection Optimization

The patent applies preliminary action by acquiring path selection reference information before the MM functional entity selects the SM functional entity. This pre-acquisition of path information enables the selection process to consider path optimization requirements in advance, thereby improving data transmission efficiency without significantly increasing the complexity of the selection process itself.

The patent introduces path selection reference information as an intermediary element that mediates between the MM functional entity and the SM functional entity selection process. This intermediary carries path optimization requirements and network information, enabling the selection to consider path optimization without requiring direct complex interactions between the MM entity and multiple SM entities, thus managing complexity while improving data transmission efficiency.

The patent applies local quality by differentiating the types of information processed: user subscription information provides user-specific characteristics while path selection reference information provides network-specific characteristics. By processing these information types locally and separately before integration in the selection process, the system achieves accurate selection based on both user and network conditions without overwhelming information processing requirements.
