Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently establishing communication sessions with local networks, particularly in high-frequency bands and 5G environments, where propagation path loss and data transmission efficiency are critical issues.
Innovation Solution
The method involves using an integrated user plane entity that performs both user plane and control plane functions, allowing for efficient session establishment by selecting the appropriate user plane entity based on user information and resource allocation, thereby optimizing communication paths and reducing latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional user plane entity is used for session establishment, then the system maintains separate control plane and user plane functions, but the session establishment process becomes complex and time-consuming
Solution Approach 1:
The patent merges the control plane entity and user plane entity into a single integrated user plane entity that performs both control plane functions (session management, policy control) and user plane functions (data forwarding, packet routing). This integration eliminates the need for separate entities and their associated complex interaction protocols, thereby simplifying the session establishment process and improving efficiency.
Solution Approach 2:
The integrated user plane entity is designed as a multi-functional component that can perform multiple roles: it acts as both the control plane entity for session management and the user plane entity for data handling. This universality allows a single entity to handle diverse functions that previously required separate specialized entities, reducing overall system complexity.
2Adaptability or versatility
If multiple user plane entities are used for different communication scenarios, then communication flexibility is improved, but the selection process becomes more complex
Solution Approach 1:
The system dynamically selects the appropriate integrated user plane entity based on real-time communication requirements, user location, network conditions, and service type. The selection process uses configurable criteria and policies that can be adjusted according to varying scenarios, allowing flexible adaptation without complex manual configuration or multiple specialized entities.
3Speed
If high-frequency bands are used for wireless communication, then data transmission speed is improved, but propagation path loss increases
Solution Approach 1:
The integrated user plane entity acts as an intermediary that receives data from the base station and forwards it to the appropriate destination, optimizing the transmission path. It can select the best routing path and manage data flow to minimize propagation losses while maintaining high-speed transmission, effectively mediating between the high-frequency band advantages and the associated path loss challenges.

AI summary
Provided is a method of establishing a session for communication with a local network in a wireless communication system, the method including obtaining a request for using an integrated mode in which a user plane entity of a base station uses an integrated user plane entity that performs an operation of a user plane function (UPF) together, when a session between a local network and a user equipment (UE) is established, determining based on user information of the UE whether to accept use of an integrated mode, selecting the integrated user plane entity as a user plane entity in which the session is to be established, based on a result of the determining, and transmitting a session establishment request to the selected integrated user plane entity.
