Solution Overview
Problem
There is a lack of effective methods for implementing a common process for establishing a ground interface in 5G and eLTE systems, which hinders the adaptation to new requirements and changes in these systems.
Innovation Solution
A method involving the transmission of request and response messages between base stations and core network devices to establish and manage interfaces, including location area, PLMN, and base station type information, facilitating the configuration and management of network slices and load capacity, thereby enabling efficient interface establishment and adaptation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional one-size-fits-all network architecture is used, then the network structure is simple and easy to manage, but it cannot adapt to diverse new use cases and user needs
Solution Approach 1:
The patent segments the network into network slices, each dedicated to specific use cases (eMBB, mMTC, URLLC). This allows the network to handle diverse requirements through separate logical partitions while maintaining a unified physical infrastructure, thereby improving adaptability without proportionally increasing overall complexity
Solution Approach 2:
The patent implements a universal network architecture that can serve multiple purposes through network slicing. A single network infrastructure can simultaneously support diverse services (mobile broadband, machine type communications, ultra reliable low latency communications) by configuring different slices, achieving multi-functionality without requiring separate dedicated networks for each service type
2Adaptability or versatility
If network slices are introduced to support diverse services, then the network can adapt to different use cases, but the interface establishment process becomes more complex
Solution Approach 1:
The patent implements a feedback mechanism in the interface establishment process where the core network device provides feedback information to the base station about network status, capacity, and configuration. This allows the base station to adjust its interface establishment requests based on real-time network conditions, simplifying the overall process while maintaining support for multiple service types
Solution Approach 2:
The patent utilizes parameter changes in the interface establishment process, where the base station modifies interface parameters (such as location area information, PLMN information, base station type) based on the specific service requirements and network conditions. This dynamic parameter adjustment enables flexible adaptation to different use cases without requiring complex procedural changes
3Productivity
If the network architecture is designed to be flexible for 5G requirements, then it can support high data rates and new technologies, but the implementation process becomes more difficult
Solution Approach 1:
The patent applies preliminary action by pre-configuring network slice parameters and interface settings before actual service deployment. The core network device prepares and provides feedback information in advance, allowing the base station to establish interfaces more efficiently when service requests arrive, thereby facilitating the implementation of high-capacity 5G services

AI summary
Provided are a method, apparatus and system for implementing a common process. The method includes that: a base station transmits a first request message to a CN device, the first request message being used for applying for establishing a first interface, the first interface being an interface between a radio access network (RAN) to which the base station belongs and a CN, and the first request message carrying at least one of: location area information of a specific geographical area configured for paging a UE, information of a public land mobile network (PLMN) supported by the base station, and base station type information of the base station; and the base station receives a first response message transmitted by the CN device, where the first response message is used for indicating that the first interface has been successfully established.
