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

VSEngineering 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

Engineering Contradiction:
Improvelink selection flexibilityVSAvoiduser involvement complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #25Self-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.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If static link selection is used, then device complexity is reduced, but productivity and adaptability deteriorate

Engineering Contradiction:
Improvecontrol overheadVSAvoiddata rate efficiency
Core Design Contradiction:
Device complexityVSProductivity

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #3Local quality

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

Engineering Contradiction:
Improvedata rateVSAvoidsignaling overhead
Core Design Contradiction:
SpeedVSLoss of energy

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.

Inventive Principle:
Principle #3Local quality

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.
