Solution Overview
Problem
There is no existing communication system that integrates Digital Enhanced Cordless Telecommunications (DECT) and Long-Term Evolution (LTE) communication, limiting the ability to transfer data between DECT terminals and LTE base stations.
Innovation Solution
A communication device with both DECT and LTE communication units, allowing data transfer between DECT terminals and LTE base stations by verifying connection states and managing communication links through an LTE carrier gateway.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If DECT and LTE communication systems operate independently, then each system maintains its own simplicity and reliability, but data transfer between DECT terminals and LTE base stations cannot be achieved
Solution Approach 1:
The patent merges DECT and LTE communication systems by integrating an LTE communication unit into the DECT base station. The DECT base station includes both DECT communication units for local wireless communication and LTE communication units for cellular network connectivity, enabling data transfer between DECT terminals and LTE base stations through the integrated architecture.
Solution Approach 2:
The patent introduces a gateway as an intermediary component that facilitates communication between DECT and LTE systems. The gateway translates and routes data between the DECT terminal and LTE base station, enabling interoperability between the two different communication technologies without requiring direct integration of all components.
2Reliability
If connection state verification is performed for LTE links, then communication reliability is improved, but connection establishment time increases
Solution Approach 1:
The patent performs connection state verification in advance before actual data communication begins. The DECT base station verifies whether the LTE link is connected and obtains connection information beforehand, so that when data transfer is requested, the connection status is already confirmed and no additional verification time is needed during data transmission.
Solution Approach 2:
The patent implements a feedback mechanism where the DECT base station receives connection information from the LTE base station and uses this feedback to control DECT terminal connections. The connection state is continuously monitored and fed back to manage subsequent communication sessions efficiently.

AI summary
Data is transferred between a DECT terminal and an LTE base station. A base unit includes a DECT communication unit and an LTE communication unit, the DECT communication unit performing DECT communication with a DECT terminal, and the LTE communication unit transmitting and receiving data with the DECT communication unit and performing LTE communication with an LTE carrier gateway through an LTE base station. The DECT communication unit transmits a connection verification request to the LTE communication unit in order to verify a connection state of an LTE link with the LTE carrier gateway. The LTE communication unit transmits a connection verification response to the DECT communication unit in response to the connection verification request in a case where an LTE link is connected. The DECT communication unit, in a case where the DECT communication unit receives a DECT connection request for requesting connection of an DECT link from the DECT terminal and receives the connection verification response from the LTE communication unit, transmits a DECT connection response to the DECT terminal in response to the DECT connection request.
