Base Station Inter-Communication Setup Without UE Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile cellular digital telecommunication networks face challenges in establishing efficient communication links between base stations without relying on user equipment detection, which can lead to increased latency and potential handover failures during network handovers.
Innovation Solution
A method that enables direct communication between base stations by receiving messages indicative of neighboring base stations, allowing for the setup of communication links and handovers independently of user equipment detection, using the X2 interface and IP addresses to establish connections and facilitate early setup of communication links and robust handovers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment detection is used to establish base station communication links, then the system follows standard procedures, but latency increases and handover failures may occur
Solution Approach 1:
The patent applies preliminary action by enabling base stations to proactively discover and establish communication links with neighboring base stations before user equipment needs to perform handover. The base station receives indication information about neighboring base stations, obtains their identification information, and sets up X2 interface communication links in advance, eliminating the need for delayed user equipment detection and reducing handover latency.
2Productivity
If base stations establish communication links independently of user equipment detection, then handover latency is reduced, but the complexity of base station discovery and link setup increases
Solution Approach 1:
The patent uses an intermediary approach by introducing indication information as a mediator that carries neighboring base station identification data. This intermediary mechanism simplifies the discovery process compared to complex direct detection methods, as the indication information systematically provides the necessary neighbor relationship data to base stations, enabling efficient link setup without excessive complexity.
3Reliability
If communication links are established before handover, then handover failures are minimized, but additional message exchanges and processing are required
Solution Approach 1:
The patent applies merging by combining the base station discovery function with the existing indication information mechanism. Rather than creating separate complex discovery protocols, the invention merges neighbor relationship indication into the existing signaling framework, allowing base stations to obtain neighboring base station information through integrated message exchanges that serve multiple purposes, thereby reducing overall signaling overhead.

AI summary
The invention relates to a method of inter base station communication comprising: - receiving a first message (118) being indicative of a neighboring second base station (2) by a first base station (1), - sending a second message (120) to the second base station, - in response to the second message, receiving a third message (124) comprising information being indicative of at least a third base station (3), the third base station being a neighbor of the second base station, using the information received with the third message for enabling communication (128) between the first base station and the third base station independently of any user equipment detection of the third base station.
