Network Node Data Link Selection for Packet Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunication networks require user involvement in selecting data links for packet-switched services between IMT and MMW links, leading to inefficient data transmission and poor user experience due to static link selection that does not differentiate between service types.
Innovation Solution
A method and device that select data links based on current data rates and service types at a network node, automatically allocating packet-switched services to either IMT or MMW links without user involvement, optimizing resource usage and reducing control overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If user involvement is required for link selection, then link selection flexibility is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The network node automatically performs link selection for packet-switched services based on service type and current data rate requirements, eliminating the need for user involvement. The system serves itself by making intelligent decisions about which link (IMT or MMW) to use for each service.
Solution Approach 2:
The network node acts as an intermediary between the mobile station and the multiple available links. It receives service type information, determines the appropriate link based on current data rate requirements, and manages the link selection process without requiring user intervention.
2Device complexity
If static link selection is used, then device complexity is reduced, but productivity and adaptability deteriorate
Solution Approach 1:
The system dynamically selects links based on real-time data rate requirements of different services. Instead of a static configuration, the network node continuously evaluates current data rate needs and automatically adjusts link selection to optimize performance for each packet-switched service.
Solution Approach 2:
Different link selection strategies are applied locally to different services based on their specific requirements. Low data rate services (e.g., VoIP, chat) are assigned to IMT links, while high data rate services (e.g., FTP, HD video) are assigned to MMW links, optimizing each service's performance characteristics.
3Speed
If MMW link is used for all services, then data rate is improved, but loss of energy and productivity deteriorate due to signaling overhead
Solution Approach 1:
The patent applies different link types to different services based on their data rate requirements. Low data rate services use IMT links with lower signaling overhead, while only high data rate services use MMW links, optimizing the balance between data rate and signaling overhead for each service.

AI summary
A method of transmitting data in a telecommunication network between a mobile station (101) and a mobile radio network (100) and corresponding device for providing a first data link (110) and a second data link (120), wherein the data link for transmitting a data stream of a packet switched service is selected from the first data link (110) and the second data link (120) at a network node (181, 182, 190) of the mobile radio network (100) depending on information about a current data rate of the data stream or information about a service type of the data stream.
