研究目的
Introducing a noble concept and design of Local Area Data Network (LADN) for 5G System Architecture to provide high data rate, low latency, and service localization, and comparing two alternative solutions for handling LADN sessions considering UE power consumptions and human mobility patterns.
研究成果
The study concludes that the proposed LADN concept enables 5G applications with low latency and high data rate requirements. Solution A is better in terms of UE power consumption for few downlink data arrivals, while Solution B should be considered as an option for operators due to its efficiency with higher downlink data arrival rates.
研究不足
The study's limitations include the assumption of specific mobility patterns and downlink data arrival rates, which may not cover all real-world scenarios. The impact of varying LADN densities on performance is also not fully explored.
1：Experimental Design and Method Selection:
The study introduces the concept of LADN and compares two solutions for handling LADN sessions. It uses simulation to analyze the solutions based on UE power consumption and human mobility patterns.
2：Sample Selection and Data Sources:
The simulation uses a levy walk model to reflect human mobility patterns, with parameters set to default values for flight length, direction, flight time, and pause time.
3：List of Experimental Equipment and Materials:
Not explicitly mentioned.
4：Experimental Procedures and Operational Workflow:
The simulation iterates steps for a pre-defined simulation time, using a levy walk model to generate user movements and count registration updates and false paging occurrences.
5：Data Analysis Methods:
The study analyzes the number of registration updates and false paging occurrences to compare the two solutions in terms of UE power consumption.
