Dynamic Network Partition Registry for Cellular Core
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular network configurations are inflexible and static, making it difficult to rapidly deploy and update network partitions, especially in virtualized environments where dynamic changes are necessary to support fast service innovation and varied business models.
Innovation Solution
A method and system for dynamically updating and selecting network partitions by maintaining a registry of network partitions, where each entry associates an authorization entity and service capabilities, enabling ad-hoc creation, commissioning, and decommissioning of network partitions, and facilitating network partition selection through registration and selection control messages.

Engineering Contradiction Analysis
1Productivity
If the polling interval for checking updated MME lists is increased to meet fast deployment times, then deployment speed improves, but network traffic increases
Solution Approach 1:
The system dynamically adjusts the polling interval based on operational conditions. When a network partition transitions to an operational state, the polling interval for associated MMEs is increased to ensure timely detection of updates, while maintaining lower intervals only when necessary. This dynamic adjustment enables fast deployment response without continuously generating high network traffic during stable periods.
Solution Approach 2:
The polling interval parameter is changed adaptively based on the operational state of network partitions. The system monitors partition states and modifies the polling frequency accordingly, increasing the interval when partitions are stable and decreasing it when changes are detected. This parameter change strategy achieves fast deployment capability while minimizing unnecessary network traffic generation.
2Manufacturing precision
If manual configuration of MMEs is used in the base station, then configuration accuracy is maintained, but flexibility and update speed deteriorate
Solution Approach 1:
The base station automatically discovers and configures MMEs through the registry system without requiring manual intervention. When MMEs are added or updated in the network, the base station autonomously queries the registry, retrieves updated MME lists, and configures itself accordingly. This self-service mechanism maintains configuration accuracy through automated validation while providing the flexibility to rapidly adapt to network changes.
Solution Approach 2:
The system implements a feedback mechanism where the base station continuously monitors the registry for MME updates and automatically adjusts its configuration. The registry provides real-time information about operational MMEs, and the base station uses this feedback to maintain accurate configurations without manual intervention, achieving both precision and adaptability.
3Quantity of substance
If low-periodicity polling is used for MME updates, then network traffic is reduced, but the ability to maintain up-to-date information deteriorates
Solution Approach 1:
The polling periodicity is dynamically adjusted based on network conditions and partition operational states. During periods of network stability, lower polling frequency is used to minimize traffic. When partition transitions occur or updates are detected in the registry, the system automatically increases polling frequency to ensure the base station receives timely MME update information, thus maintaining information freshness without excessive traffic during stable periods.
Solution Approach 2:
The polling interval parameter is adaptively changed based on detected network events. When the registry indicates MME additions or removals, the system decreases the polling interval to ensure rapid propagation of updates to the base station. During stable operational periods, the interval is increased to reduce network traffic. This parameter adaptation resolves the contradiction between traffic reduction and information freshness.

AI summary
In response to a transition from a previous operational state to a current operational state of a given network partition of a plurality of network partitions of a core of a cellular network, a respective entry of a registry of the plurality of network partitions is updated. Network partition selection for a terminal is effected by participating in a communication of at least one selection control message corresponding to at least one entry of the registry.
