Pre-provisioned Data Paths for Telecommunications Session Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunications networks face challenges in quickly and reliably establishing data plane sessions for user equipment due to the need for programming data paths within forwarding entities, which can be time-consuming and resource-intensive, especially when handling multiple simultaneous requests.
Innovation Solution
The method involves pre-establishing and pre-configuring data paths within forwarding entities using data path configuration information, allowing these pre-provisioned data paths to be assigned to user equipment upon request, thereby reducing the time required to set up data plane sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If data paths are programmed and configured within forwarding entities in real-time when data plane sessions are requested, then the system maintains flexibility and resource efficiency, but the session establishment time becomes excessively long (potentially several minutes)
Solution Approach 1:
The patent applies preliminary action by pre-configuring data paths within forwarding entities before data plane sessions are actually requested. The system pre-establishes forwarding rules, routing information, and data path parameters in advance, so that when a session request arrives, the data path is already prepared and can be activated immediately, reducing session establishment time from minutes to near-instantaneous while managing complexity through automated pre-provisioning
2Productivity
If data paths are pre-provisioned and pre-configured within forwarding entities, then session establishment becomes almost instantaneous, but network resources are consumed in advance
Solution Approach 1:
The patent applies partial action by pre-configuring only essential data path parameters and forwarding rules that are needed for rapid session establishment, rather than fully provisioning all possible resources in advance. The system pre-sets routing templates, forwarding tables, and basic path parameters, but leaves certain resource allocations (bandwidth, buffer sizes, specific routing decisions) to be finalized or adjusted when actual session requests arrive, thus achieving fast setup while avoiding excessive resource consumption
Solution Approach 2:
The patent applies dynamics by making the pre-configured data paths adaptable and modifiable. The pre-provisioned data paths are designed to be dynamically adjusted based on actual session requirements, allowing the system to start with pre-configured parameters and then fine-tune resource allocation, bandwidth, and routing decisions in real-time based on current network conditions and session-specific demands

AI summary
Establishing a data plane session for a user equipment with a network using an access network requires the existence of a data path in or through a forwarding entity of the network. The forwarding entity is part of the access network or is an IP edge network node, wherein the data path within the forwarding entity corresponds to a programmed data path in or through a forwarding entity defined by means of data path configuration information being used to identify the user equipment and/or the data plane session using the data path, wherein in order to establish the session, the method includes establishing the data path within the forwarding entity as an at least partly programmed and/or pre-provisioned data path, including the data path configuration information, wherein establishing the session for the user equipment involves the session and/or the user equipment to be assigned to the existing pre-provisioned data path.
