RAN Entity Registration for Tracking Area Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In future generation mobile communication networks with a flat architecture, the configuration of Tracking Areas becomes complex and labor-intensive for CN operators, particularly when ENB nodes are added or removed, leading to potential coordination issues between CN and RAN operators.
Innovation Solution
An automated method for registering Radio Access Network (RAN) entities onto Mobility Management and Paging Coordination functions, involving steps like sending registration requests, mutual authentication, and using IP multicast capabilities to associate Tracking Areas with IP addresses, simplifying the configuration process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual configuration of Tracking Areas is performed in CN nodes when RAN configuration changes, then configuration accuracy can be maintained, but operator workload increases significantly and coordination complexity worsens
Solution Approach 1:
The RAN entity autonomously performs self-registration with the CN node by automatically sending registration requests containing its identity and TA information upon configuration changes, eliminating the need for manual operator intervention while maintaining configuration accuracy through automated procedures
Solution Approach 2:
The RAN entity is pre-configured with TA information and automatically initiates registration procedures before actual operation begins or when configuration changes occur, ensuring the CN node has up-to-date RAN entity information without requiring manual updates
2Stability of the object's composition
If manual configuration updates are performed in CN nodes for each RAN entity change, then configuration consistency can be maintained, but coordination complexity and setup time increase
Solution Approach 1:
The automated registration mechanism establishes a feedback loop where the RAN entity automatically notifies the CN node of its configuration status and any changes, enabling the CN node to maintain consistent configuration information without complex manual coordination procedures
Solution Approach 2:
The manual mechanical configuration process is replaced with automated electronic registration procedures, where the RAN entity automatically sends registration requests to the CN node, substituting operator manual updates with automated system-to-system communication
3Ease of operation
If CN nodes are configured on a permanent basis without automatic updates, then operational simplicity is maintained, but configuration timeliness deteriorates when RAN changes occur
Solution Approach 1:
The automated registration mechanism ensures continuous synchronization between RAN configuration and CN node information by automatically detecting and reporting configuration changes, maintaining timeliness without compromising operational simplicity

AI summary
The method includes sending a request to a core network entity to register the radio access network entity with the core network entity for at least one tracking area, the core network entity being in charge of mobility management and/or paging coordination in a cellular mobile communication network. The method further includes receiving a notification of an acceptation or a rejection of said request that indicates if the core network entity has accepted the registration. The radio access network entity is configured to perform the method. The core network entity is configured to interface with the radio access network entity to perform the method.
