Solution Overview

Problem

Existing mobile terminals in wireless telecommunications systems face usability issues due to insufficient user interface elements, and existing solutions that extend these capabilities require additional radio resources for signaling, which can be costly and complex.

Innovation Solution

A method and system that connect a subscriber terminal to a sub-terminal using a proximity wireless interface, allowing the sub-terminal to utilize the subscriber terminal's identity and radio link, thereby reducing the need for direct signaling with the infrastructure and releasing radio resources for data transfer, and eliminating the need for a transmitter in the sub-terminal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a mobile terminal is equipped with an extended user interface to improve usability, then user interface capability is improved, but radio resource consumption increases due to independent connection signaling

Engineering Contradiction:

Improveuser interface capabilityVSAvoidradio resource consumption

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The sub-terminal is nested within the subscriber terminal's radio connection. The sub-terminal uses the subscriber terminal's established radio link and identity, nesting its communication capabilities inside the existing terminal-infrastructure connection without requiring a separate independent connection to the network infrastructure.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The sub-terminal copies the subscriber terminal's identity for network access purposes. By using the same subscriber identity, the sub-terminal can communicate with the infrastructure through the existing radio link without establishing new signaling connections, thereby avoiding additional radio resource consumption.

Inventive Principle:

Principle #26Copying

2Adaptability or versatility

If an independent connection is established for extended user interface capabilities, then terminal functionality is improved, but device complexity increases due to additional signaling requirements

Engineering Contradiction:

Improveterminal functionalityVSAvoidsignaling complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sub-terminal's communication function is merged with the subscriber terminal's existing radio connection. Instead of maintaining separate independent connections, the system combines the sub-terminal's needs with the existing subscriber terminal infrastructure link, sharing the same radio resources and signaling pathways.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The subscriber terminal acts as an intermediary between the sub-terminal and the network infrastructure. The subscriber terminal forwards signaling and data between the infrastructure and the sub-terminal, eliminating the need for the sub-terminal to establish direct independent signaling connections with the infrastructure.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If a sub-terminal is equipped with a transmitter for direct communication with infrastructure, then communication capability is improved, but manufacturing cost increases

Engineering Contradiction:

Improvecommunication capabilityVSAvoidmanufacturing cost

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The subscriber terminal's transmitter serves multiple functions: it communicates with the network infrastructure and simultaneously enables the sub-terminal's communication needs. This multi-functionality eliminates the requirement for a separate transmitter in the sub-terminal, reducing manufacturing costs while maintaining full communication capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The subscriber terminal provides communication service to the sub-terminal using its own existing transmitter. Instead of the sub-terminal requiring its own transmitter infrastructure, it leverages the subscriber terminal's transmission capabilities, effectively making the system self-sufficient without additional hardware components.

Inventive Principle:

Principle #25Self-service

AI summary

A subscriber terminal holding a subscriber identity is connected to a sub-terminal using the identity of the subscriber terminal over a wireless proximity interface. A radio link directed from an infrastructure to the sub-terminal is requested by the subscriber terminal, and at least a portion of signalling between the sub-terminal and the wireless telecommunications infrastructure is routed via the subscriber terminal.
