Multi-hop Data Transmission in Ultra Dense Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communications systems lack a clear solution for implementing multi-hop data transmission in ultra dense networks, where complex topology structures are common due to the absence of fiber deployment in small cells, necessitating wireless backhaul and requiring efficient routing mechanisms.
Innovation Solution
A method and apparatus for multi-hop data transmission that involves a primary base station obtaining and sending route configuration information to multiple route base stations, allowing each station to determine the data transmission path between a terminal device and a serving gateway, with the ability to update paths in real-time based on QoS requirements and topology changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless backhaul is used in ultra dense networks without fiber deployment, then data transmission can be achieved in small cells deployed at simple positions, but the network topology becomes complex and routing mechanisms become difficult to implement
Solution Approach 1:
The network management system pre-establishes route configuration information between base stations before data transmission occurs. This preliminary routing setup allows base stations to forward data packets along predetermined paths without performing complex real-time routing decisions, thus resolving the contradiction between deployment flexibility and routing complexity
Solution Approach 2:
The network management system acts as an intermediary that centralizes routing decision-making. It generates and distributes route configuration information to multiple base stations, enabling them to participate in multi-hop transmission without each station needing to independently solve complex routing problems
2Reliability
If multi-hop transmission paths are established dynamically, then quality of service requirements can be met, but the signaling overhead and path establishment time increase
Solution Approach 1:
Route configuration information is pre-established by the network management system before actual data transmission begins. This allows QoS requirements to be incorporated into routing decisions in advance, eliminating the need for time-consuming dynamic path establishment during data transmission
Solution Approach 2:
While routes are pre-configured, the system maintains flexibility to update routing paths when topology changes occur or QoS requirements are not met. The network management system can dynamically adjust route configuration information to balance QoS guarantees with establishment time
