Base Station Speech Transmission Timing Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in maintaining communication quality due to unpredictable network delays in IP networks, which can lead to overlapping transmissions and interference between base station apparatuses, resulting in disrupted speech and reduced quality.
Innovation Solution
A base station apparatus and method that measure and account for network delays by calculating a delay duration and adjusting the transmission time, ensuring continuous speech transmission by transmitting speech information at a delayed transmission time derived from subsequent packet signals, thereby maintaining regular intervals and reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base station apparatuses transmit speech information based on predetermined transmission times, then communication quality should be maintained, but unpredictable network delays cause transmissions to occur at incorrect times leading to overlapping transmissions and interference
Solution Approach 1:
The base station apparatus measures the actual reception time of packet signals and compares it with the predetermined transmission time to calculate the network delay. This feedback mechanism allows the system to dynamically adjust transmission timing based on actual network conditions, resolving the contradiction between maintaining scheduled transmissions and adapting to variable network delays
Solution Approach 2:
The system performs preliminary measurement of network delay between base station apparatuses and uses this information to calculate optimal transmission timing in advance. By preparing the corrected transmission time before actual speech transmission, the system prevents timing errors from causing interference while maintaining reliable communication quality
2Loss of time
If the micro base station apparatus transmits speech information with delayed timing to compensate for network delays, then transmission timing accuracy improves, but speech playback continuity may be disrupted
Solution Approach 1:
The system performs preliminary measurement of network delay and calculates the optimal transmission time in advance, before actual speech transmission begins. This allows the micro base station to prepare the correct transmission timing without disrupting the continuity of speech playback during actual operation
Solution Approach 2:
The system continuously monitors reception time and adjusts transmission timing based on measured network delay feedback. This dynamic adjustment maintains both timing accuracy and speech continuity by adapting to actual network conditions while preserving the natural flow of speech transmission
Data Source
AI summary
A communication interface receives data at least including speech information and information related to a transmission time when the speech information should be transmitted. A processor extracts the speech information and the transmission time included in the data received by the communication interface. A wireless transmitter transmits the speech information extracted by the processor based on the transmission time extracted by the processor. When the transmission time has already passed, the wireless transmitter transmits the speech information and transmits the speech information extracted from subsequent data that follows said data at a time later than the transmission time extracted from the subsequent data.
