Telecom Network Resource Control via Packet Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current resource control methods in telecommunication networks, such as GPRS and UMTS, lack effective end-to-end Quality of Service (QoS) management across network boundaries, failing to account for varying service and customer class importance, leading to inefficiencies and potential misuse.
Innovation Solution
Implementing data packet inspection to classify and prioritize data packets based on their importance, allowing network operators to dynamically adjust resource allocation and quality parameters, thereby enabling complete control over resource distribution and preventing misuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packet inspection is implemented for QoS control, then resource distribution and QoS management are improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent applies preliminary action by classifying data packets at the beginning of their transmission path (at the GGSN entry point) before they enter the core network. This initial classification establishes QoS parameters that are then maintained throughout the network, avoiding the need for continuous inspection and reducing overall processing complexity while ensuring reliable QoS control from the outset.
Solution Approach 2:
The patent introduces an intermediary mechanism by using classification rules and QoS parameter mappings as intermediaries between the packet inspection process and the actual resource allocation. The GGSN acts as an intermediary node that translates packet characteristics into standardized QoS parameters, simplifying the control process for downstream network elements without requiring them to perform complex inspection themselves.
2Productivity
If complete network control over resource allocation is implemented, then resource utilization efficiency is improved, but loss of time due to centralized decision-making increases
Solution Approach 1:
The patent resolves this contradiction by performing preliminary classification and QoS parameter assignment at the GGSN before packets enter the core network. This upfront action establishes the resource allocation strategy in advance, allowing core network elements to simply enforce pre-determined QoS parameters without requiring real-time centralized decision-making, thus maintaining high resource utilization while minimizing time delays.
Solution Approach 2:
The patent applies dynamics by allowing QoS parameters to be adjusted based on network conditions and service requirements while maintaining a standardized control framework. The classification rules and QoS mappings can be dynamically updated without changing the fundamental architecture, enabling the system to adapt to changing conditions while preserving the efficiency benefits of centralized control.
3Adaptability or versatility
If data packet inspection is used for classification, then service and customer class importance are accounted for, but manufacturing precision and classification accuracy requirements increase
Solution Approach 1:
The patent applies local quality by implementing classification rules that are tailored to specific service types and customer classes. Different classification criteria and QoS parameter mappings are applied locally based on the packet's service category and customer profile, allowing the system to accommodate diverse service requirements with appropriate precision levels for each class rather than requiring uniform high precision across all traffic types.
Solution Approach 2:
The patent uses parameter changes by transforming packet characteristics (source, destination, service type, customer class) into standardized QoS parameters through configurable classification rules. This parameter transformation approach allows the system to adapt to different classification needs by changing the rules and mappings without requiring changes to the underlying network infrastructure, balancing versatility with manageable precision requirements.
4Ease of operation
If quasi-static parametrizing is used for logical connections, then network element control is simplified, but adaptability to varying service requirements deteriorates

AI summary
The invention relates to a method for controlling resources in network elements of a communication network, in particular a data network or a mobile data network. The idea of the invention is the use of a data packet inspection for the Quality of Service (QoS) control in telecommunication networks. Based on information obtained from data packets, a network resource corresponding to the content of each data packet is provided in the network elements. A dynamic allowance for services and customer classes or quality and resource control is a novel possibility by means of the above application of packet inspection.
