DECT Base Station Codec Matching for Handset Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Incompatibility between new DECT base stations and old handsets, or new handsets and old DECT base stations, prevents normal voice communication due to lack of compatibility with different voice codecs.
Innovation Solution
A DECT base station and handset system equipped with multiple voice codecs that sequentially match and prioritize codec compatibility through data packets, ensuring successful voice communication by selecting the appropriate codec for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a new voice codec is installed in the DECT base station to improve sound quality, then the voice communication quality is improved, but the compatibility with old handsets deteriorates
Solution Approach 1:
The DECT base station is equipped with multiple voice codecs (new and old) simultaneously, enabling it to perform multiple functions: supporting both high-quality voice communication with new handsets and backward compatibility with old handsets. The base station can adaptively select which codec to use based on the handset type, thus achieving universal compatibility across different device generations.
2Reliability
If the DECT base station is upgraded with a new voice codec, then the performance of the base station is improved, but the compatibility with new handsets equipped with old codecs deteriorates
Solution Approach 1:
The base station employs dynamic codec selection capability, where the codec used for communication is not fixed but changes adaptively based on the capabilities of the connected handset. When a new handset with an old codec connects, the base station dynamically switches to use the old codec. When a new handset with a new codec connects, it dynamically switches to use the new codec for optimal performance.
3Adaptability or versatility
If sequential codec matching is implemented to ensure compatibility, then the compatibility between base station and handset is improved, but the communication establishment time increases
Solution Approach 1:
The handsets and base stations are pre-configured with information about their supported codecs. During the connection establishment process, this pre-stored codec information is quickly exchanged and matched without requiring time-consuming trial-and-error or complex real-time analysis. The sequential matching process leverages this preliminary preparation to rapidly determine compatibility.

AI summary
Disclosed are a Digital Enhanced Cordless Telecommunications (DECT) base station, a handset and a communication system. The DECT base station is installed with at least two different voice codecs and is configured to sequentially judge whether the voice codecs of the DECT base station match voice codecs of a handset according to a first codec information data packet sent by the handset, and when a matching is successful, send a response information to the handset to perform voice communication with the handset through a matched voice codec. By using the DECT base station can guarantee the normal voice communication between the DECT base station and the handset in the condition of installing voice codecs in the DECT base station.
