MCE ABS Configuration for Inter-Cell Interference Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In heterogeneous networks, the transmission of ABS status and configuration information between base stations using only X2 interface messages and procedures complicates actual deployment, especially when base stations from different manufacturers cannot interact effectively for inter-cell interference coordination.
Innovation Solution
A method and system where a multi-cell/multi-media cooperation entity (MCE) determines and sends ABS configuration information to base stations within ICIC areas, using M2 interface messages and procedures, allowing for the coordination of ABS subframes and status information transfer, enabling effective inter-cell interference coordination even among base stations from different manufacturers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base stations use only X2 interface messages and procedures to transmit ABS status and configuration information, then inter-cell interference coordination can be achieved between base stations, but the deployment complexity increases significantly especially when base stations are from different manufacturers
Solution Approach 1:
The patent introduces the M2 interface as an intermediary between the MCE and base stations for transmitting ABS configuration information. This mediator approach allows the MCE to centrally manage and distribute ABS patterns to multiple base stations, simplifying the interaction model and reducing deployment complexity compared to direct X2 interface communication between all base station pairs.
Solution Approach 2:
The patent segments the interference coordination function by separating the MCE (which determines ABS patterns) from the base stations (which execute and report). This segmentation allows different manufacturers' base stations to work together through the standardized M2 interface, reducing the complexity of cross-vendor deployment while maintaining reliable ICIC.
2Adaptability or versatility
If base stations from different manufacturers cannot interact effectively via X2 interface, then manufacturer compatibility is maintained, but inter-cell interference coordination fails
Solution Approach 1:
The M2 interface serves as a universal communication mechanism that works across base stations from different manufacturers. The standardized interface definitions and procedures allow any MCE to manage ABS patterns for any connected base stations, providing manufacturer-agnostic interoperability while ensuring reliable ICIC functionality.
3Productivity
If ABS configuration information is transmitted through X2 interface between base stations, then direct coordination is achieved, but the system complexity and difficulty of actual deployment increases
Solution Approach 1:
The MCE acts as a centralized intermediary that simplifies the coordination process. Instead of requiring complex peer-to-peer X2 interactions between multiple base stations, the MCE receives reports from base stations and distributes ABS patterns through the M2 interface, making the system easier to deploy and operate while maintaining coordination efficiency.

AI summary
Provided are a method and system for processing configuration information. The method includes: an MCE determines ABS configuration information corresponding to each base station in one or multiple base stations, wherein the one or multiple base stations are all controlled by the MCE and the one or multiple base stations constitute one or more ICIC areas; and the MCE sends the ABS configuration information, corresponding to each ICIC area of the one or more ICIC areas, to each base station of one or multiple base stations in the ICIC area. A technical solution provided according to the present invention achieves that when more base stations all belong a same MBSFN area (that is, an ICIC area controlled by a same MCE), ABS status information and ABS configuration information are transmitted between the MCE and the base stations controlled by the MCE, so as to achieve an ICIC function.
