Rerouting Unit for Marked Data Packet Billing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packet switching technologies in mobile networks face inefficiencies in billing, as they require exhaustive examination of all data packets to determine service-related billing, which is time-consuming and resource-intensive.
Innovation Solution
Implementing a rerouting unit that inserts and detects an identification feature in data packets, allowing only relevant packets to be diverted and recorded, thereby enabling service- or data-specific billing with reduced effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the content of each transmitted data packet is examined to enable service-dependent billing, then billing precision is improved, but device complexity and processing time increase considerably
Solution Approach 1:
The patent applies preliminary action by inserting identification features into data packets at the source (terminal or server) before transmission. This pre-marking allows the rerouting unit to simply detect these features rather than examining packet contents, thereby achieving precise service identification without complex processing at the billing point.
Solution Approach 2:
The patent introduces an intermediary element - the identification feature inserted into data packets - that mediates between the service request and the billing process. This identifier acts as a carrier that conveys service information without requiring the billing system to analyze the actual packet content, thus simplifying the billing device while maintaining precision.
2Measurement precision
If all data packets are examined to determine service-related billing, then billing accuracy is improved, but productivity decreases due to time-consuming processing
Solution Approach 1:
The patent extracts the service identification information from the packet content and places it as a separate identification feature in the packet header or as a distinct marker. This extraction allows the billing system to quickly detect service type without examining the entire packet content, thereby maintaining billing accuracy while significantly improving processing speed.
Solution Approach 2:
The identification feature is inserted into data packets at the source before transmission. This preliminary marking enables fast detection at the rerouting unit without requiring time-consuming content examination, thus maintaining billing accuracy while improving packet processing productivity.
3Measurement precision
If resources are provided and maintained for examining each data packet, then service-dependent detection is improved, but operational costs increase
Solution Approach 1:
The identification feature serves as an intermediary that carries service information without requiring the billing infrastructure to invest in complex packet analysis capabilities. The rerouting unit only needs simple detection mechanisms to identify these features, dramatically reducing the resources and operational costs required while maintaining service-dependent detection capability.

AI summary
The method involves performing rerouted bidirectional data transfer of data packets (80) between a mobile radio terminal (14) and a server (22) by a telecommunications network, a gateway (32), a bypass unit (34) and a packet-oriented data network (18). An identification characteristic (44) with respect to service or data is inserted into the packets for the data transfer. The packets are searched with the bypass unit based on the characteristic by an identification unit (42). The data transfer is detected over the bypass unit by a detecting unit based on the data packets. Independent claims are also included for the following: (1) a detection system for transfer of data packets between a terminal of a telecommunication network and a server in a packet-oriented data network (2) a computer program product comprising computer-readable instructions to perform a method for detecting transfer of data packets between a terminal of a telecommunications network and a server in a packet-oriented data network.
