Base Station Local Storage for Communication Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunication systems fail to establish communication services when the central database with communication identifiers is unavailable, particularly in emergency situations where the connection link between base stations and the core network is broken.
Innovation Solution
Implementing a method where base stations store communication identifiers locally after detecting a disconnection from the core network, allowing them to establish communication services without relying on the central database, by receiving and storing at least one communication identifier and using it to provide communication services to user equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base station relies on the central database for communication identifiers, then communication services can be established under normal conditions, but communication services cannot be established when the connection to the central database is unavailable
Solution Approach 1:
The base station performs preliminary actions by storing communication identifiers locally in its memory before the connection to the central database is lost. This allows the base station to continue providing communication services using the pre-stored identifiers even when the central database becomes unavailable, thereby resolving the contradiction between service reliability and database dependency.
2Reliability
If the base station stores communication identifiers locally, then communication services can be provided during disconnection, but the base station requires additional local storage capacity
Solution Approach 1:
The invention extracts only the essential communication identifiers from the central database and stores them locally at the base station, rather than storing the entire database. This selective extraction allows the base station to maintain service continuity during disconnection while minimizing the additional storage capacity required, thus resolving the contradiction between reliability and storage volume.
3Reliability
If the base station operates independently from the central database, then services can continue during failures, but the system loses centralized control and coordination
Solution Approach 1:
The base station dynamically adapts its operating mode based on the availability of the central database. When the database is accessible, the base station operates in normal mode with centralized control. When the database becomes unavailable, the base station automatically switches to independent operation mode using locally stored identifiers, thereby maintaining service availability while preserving centralized control when possible. This dynamic adaptation resolves the contradiction between reliability during failures and system flexibility.

AI summary
The invention relates to a method for establishing a communication service with a user equipment in the coverage area of a base station is disclosed. The base station is part of a telecommunication system comprising a plurality of base stations connected to a core network containing a connection information database. In the method, at least one communication identifier is received by the base station of the user equipment in the coverage area of the base station after the base station has processed information indicative of a disconnection between the base station and the connection information database, e.g. a disconnection between the base station and the core network. The received at least one communication identifier is stored in a local storage associated with the base station. The communication service is established via the base station using the communication identifier from the local storage.
