Composite Source Connection Identifier for Telecommunications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In telecommunications networks, especially those following 3GPP standards, existing connection management systems face issues due to non-unique application identifiers across nodes, leading to confusion and errors when establishing connections, particularly during handover processes and when multiple nodes assign the same identifiers by chance.
Innovation Solution
Incorporating a source node identifier alongside the application identifier in connection request messages to create a unique source connection identifier, ensuring distinct identification of connections across the network, which can be globally unique or unique within a PLMN network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If application identifiers are generated uniquely within each source node, then connection management within a single node is simplified, but identifier uniqueness cannot be guaranteed across multiple nodes in the network
Solution Approach 1:
The identifier system is segmented into two parts: a node-specific component (source node identifier) and a connection-specific component (application identifier). This segmentation allows each part to maintain its own uniqueness properties while the combination provides global uniqueness. The source node identifier is unique to each node in the network, while the application identifier is unique within each node, and together they form a globally unique source connection identifier.
Solution Approach 2:
The source node identifier acts as an intermediary element that bridges the gap between local uniqueness (application identifier within a node) and global uniqueness (across the network). By introducing this intermediate identifier component, the system resolves the contradiction by allowing simple local management while ensuring global distinction through the combined identifier structure.
2Quantity of substance
If application identifiers are reused across different source nodes, then identifier space is efficiently utilized, but connection identification becomes ambiguous at destination nodes
Solution Approach 1:
The solution moves from a one-dimensional identifier space (application identifier alone) to a two-dimensional identifier space by adding the source node identifier dimension. This allows identifier reuse across different nodes (efficient utilization of identifier space) while maintaining unique identification through the combination of node identifier and application identifier, preventing information loss at the destination.
3Reliability
If source connection identifiers include both source node identifier and application identifier, then connection uniqueness is guaranteed across the network, but message overhead increases
Solution Approach 1:
The source node identifier and application identifier are merged into a single composite source connection identifier that is transmitted together in connection request messages. This merging ensures connection uniqueness across the network while managing the increased information content as a unified identifier structure, reducing the need for separate handling of multiple identifier fields.

AI summary
A method and system are proposed for establishing a requested connection between a source node and a destination node in a telecommunications network. The system and method are described in relation to a 3GPP network, but are applicable to other types of networks. The method includes generating a source application identifier for the connection within the source node, retrieving a source node identifier for the source node and transmitting the source application identifier and the source node identifier to the destination to provide a source connection identifier for the requested connection between the source node and the destination node.
