Coordinated Communication Interface for Base Station Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eCoMP technologies face performance issues due to delayed transmission using SCTP for control plane interfaces and data loss/unreliability using UDP for user plane interfaces, affecting inter-base-station coordinated communication.
Innovation Solution
A coordinated communication method and system that employs a control node to establish distinct interfaces for sending and receiving measurement information, using SCTP for reliable control plane communication and UDP for faster user plane data transmission, enabling quick and reliable resource configuration between base stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base stations use a control plane interface (SCTP) to transmit measurement information and resource information, then transmission reliability is improved, but transmission delay increases
Solution Approach 1:
The patent divides the transmission interface into two separate interfaces: a control plane interface (using SCTP) for transmitting resource configuration information, and a user plane interface (using UDP) for transmitting measurement information. This segmentation allows each interface to use the most appropriate protocol for its specific function, achieving both reliability for control signaling and low delay for data transmission.
2Loss of time
If base stations use a user plane interface (UDP) to transmit measurement information and resource information, then transmission delay is reduced, but transmission reliability deteriorates
Solution Approach 1:
The patent segments the transmission functions by creating separate control plane and user plane interfaces. The user plane interface using UDP handles measurement information transmission with low delay requirements, while the control plane interface using SCTP handles resource configuration information requiring high reliability, thus resolving the contradiction between speed and reliability.
3Device complexity
If a single interface is used for both control and user plane communication, then device complexity is reduced, but performance of inter-base-station coordinated communication deteriorates
Solution Approach 1:
The patent introduces a dual-interface architecture separating control plane and user plane communication. Although this increases interface complexity, it significantly improves inter-base-station coordinated communication performance by allowing optimized protocol selection for each communication type: SCTP for reliable control signaling and UDP for fast measurement data exchange.

AI summary
Embodiments of the present disclosure provide a coordinated communication method which can reduce a transmission delay in inter-base-station coordinated communication when reliability of the inter-base-station coordinated communication is ensured. The method may include: sending first instruction information and second instruction information to each of n first base stations, so that each of the n first base stations establishes a first interface and a second interface according to the first instruction information and the second instruction information; receiving, by using the second interface, measurement information reported by each of the n first base stations, where the measurement information is a measurement results of m cells; determining resource configuration information of the m cells according to the measurement information; and sending the resource configuration information of the m cells to each of the n first base stations by using the first interface.
