Radio Access Network Server Redundancy via Multi-Client Connection Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing architectures for radio access networks that split processes into higher and lower layers lack specific considerations for achieving redundancy in the higher layer processes.
Innovation Solution
A communication apparatus comprising a first layer processing unit, an establishing unit, an obtaining unit, and a communication processing unit, which performs processes of a first layer in a radio access network, establishes connections with multiple clients performing higher layer processes, obtains connection state information from a first client, and transmits this information to a second client to achieve redundancy in higher layer processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If processes are split into higher and lower layers and performed in separate apparatuses, then functional separation and flexibility are improved, but redundancy in higher layer processes cannot be achieved
Solution Approach 1:
The server establishes connection relationships with multiple clients (first client and second client) in advance before any failure occurs. This preliminary setup of multiple potential connections enables the system to quickly switch to a standby client when the active client fails, achieving redundancy without compromising the functional separation between layers.
Solution Approach 2:
The server acts as an intermediary that manages multiple clients and their connection states. By maintaining awareness of connection states between the server and multiple clients, and by being able to switch connections, the server enables redundancy at the higher layer while preserving the architectural separation between layers.
2Reliability
If multiple clients are connected to the server, then redundancy is improved, but connection management complexity increases
Solution Approach 1:
The server obtains and monitors connection state information from multiple clients continuously. This feedback mechanism allows the server to automatically detect when a client connection fails and trigger appropriate switching actions, simplifying the management of multiple connections by making the system self-aware and self-regulating rather than requiring complex manual management.
Solution Approach 2:
The system enables automatic connection switching based on monitored connection states. When the server detects that the connection with the first client has failed, it can automatically switch to the second client without requiring external intervention, thereby reducing the operational complexity of managing multiple redundant connections.

AI summary
In an architecture in which the inside of a radio access network is split into two layers and the processes are performed in separate apparatuses, respectively, to achieve the redundancy of the processes of the higher layer. A server apparatus 100 is a communication apparatus that comprises a first layer processing unit 141 configured to perform a process of a first layer in a radio access network, an establishing unit 143 configured to perform a process for establishing connections with two or more clients performing a process of a second layer, which is higher than the first layer, an obtaining unit 145 configured to obtain information related to a connection state with a first client performing the process of the second layer, and a communication processing unit 147 configured to transmit, to a second client, the information related to the connection state with the first client.
