Solution Overview
Problem
Current wireless communication systems face inefficiencies in managing network configurations between master base stations and secondary base stations, particularly in dual connectivity scenarios, requiring complex operations for setting and resetting destination information, especially during events with increased user traffic or when different network operators are involved.
Innovation Solution
A wireless communication system that includes a master base station, secondary base stations, and a relay communication device with a destination control unit and a transfer path control unit, which facilitates the generation and management of identification information for wireless access networks, allowing the relay device to notify secondary base stations of system information and the master base station of permitted wireless resources, thereby simplifying the communication process and reducing operational complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large number of secondary base stations are added to increase coverage area for dual connectivity, then the area where DC is performed increases, but the complexity of resetting destination information in the transport network layer increases
Solution Approach 1:
The patent introduces a relay communication device as an intermediary between the master base station and secondary base stations. This relay device manages the transport network layer connections, acting as a mediator that handles destination information routing. When secondary base stations are added or removed, the relay device manages the destination information updates, preventing the need for widespread resets across the entire network and thus reducing the complexity associated with network reconfiguration.
2Adaptability or versatility
If destination information in the transport network layer is changed frequently to accommodate temporary network configurations, then the network can adapt to increased user traffic, but the operational efficiency decreases due to repeated change operations
Solution Approach 1:
The relay communication device pre-establishes and manages destination information for multiple secondary base stations before they are actively needed. When temporary network configurations are required (such as during events with increased user traffic), the relay device can quickly activate pre-configured connections without requiring frequent change operations. This preliminary preparation maintains network adaptability while minimizing the operational overhead of repeated reconfigurations.
3Adaptability or versatility
If different network operators manage master and secondary base stations, then resource sharing between operators is enabled, but the complexity of adjusting operations for mutual destination sharing increases
Solution Approach 1:
The relay communication device serves as a universal platform that manages connections between master base stations and secondary base stations regardless of which network operator manages them. It implements a standardized interface and destination information management mechanism that works across different operators' networks. This multi-functional approach enables resource sharing between operators while avoiding the need for each operator to implement separate, customized solutions, thus reducing the overall complexity of adjusting operations for mutual destination sharing.

AI summary
SeNBs generate first identification information for specifying wireless access networks on the basis of system information provided in a notification from a relay communication device, wirelessly transmit the first identification information to UE, and notifiy an MeNB of second identification information for specifying wireless resources, utilization of which is permitted, via the relay communication device. The MeNB sets, in a signal directed to an SeNB selected from the SeNBs in the first identification information received from the UE, the first identification information of the SeNB, sets the second identification information of the selected SeNB in the signal directed to the UE, and transmits the signal to the relay communication device. The relay communication device transfers the signal received from the master base station to the SeNB in accordance with the first identification or the second identification information set in the signal. The SeNB wirelessly transmits the signal transferred from the relay communication device and directed to the UE.
