DECT Synchronization Pulse Transmission for Fast Connection Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional DECT communication systems face inefficiencies in call setup due to the need for continuous synchronization pulses during idle mode, leading to prolonged synchronization times and reduced battery life in mobile components.
Innovation Solution
Implementing a processing unit to analyze synchronization pulses with amplified information, allowing for the rapid establishment of synchronous user channel connections by transmitting multiple synchronization pulses during idle mode only when a connection request is received, thereby eliminating the need for continuous dummy bearers.

Engineering Contradiction Analysis
1Speed
If continuous synchronization pulses (dummy bearers) are transmitted every 10 milliseconds, then mobile components can maintain synchronization and quickly establish connections, but energy consumption increases and battery life decreases
Solution Approach 1:
The patent applies periodic action by transitioning from continuous dummy bearer transmission to periodic transmission only when needed. The base station transmits synchronization pulses periodically based on connection requests rather than continuously, reducing energy consumption while maintaining synchronization capability when required.
Solution Approach 2:
The system dynamically adjusts its operation mode between asynchronous idle mode (no synchronization pulses) and synchronous mode (synchronization pulses transmitted). This dynamic switching allows the system to optimize between energy consumption and connection establishment speed based on real-time needs.
2Speed
If mobile components continuously monitor for synchronization pulses, then rapid connection establishment is possible, but receiver operation time increases and battery life decreases
Solution Approach 1:
Mobile components periodically enable their receivers to monitor for synchronization pulses rather than continuously operating. The receiver is activated only when a connection request is detected, reducing the duration of receiver operation while maintaining the ability to quickly establish connections when needed.
Solution Approach 2:
The mobile component autonomously manages its receiver state by enabling it only when a connection request is received, rather than continuously monitoring. This self-service approach reduces energy consumption while maintaining synchronization capability.
3Reliability
If the base station continuously transmits dummy bearers, then all mobile components can synchronize, but transmission energy consumption increases
Solution Approach 1:
The base station transitions from continuous dummy bearer transmission to periodic transmission only when connection requests are received. This periodic action maintains synchronization reliability when needed while significantly reducing transmission energy consumption during idle periods.
Solution Approach 2:
The system changes the transmission parameter from continuous to periodic based on operational state. When in idle mode, no synchronization pulses are transmitted; when connection requests are detected, synchronization pulses are transmitted periodically to ensure reliable connection establishment.

AI summary
In order to be able to control the creation of a user channel connection in a communication system using wireless communication between at least one mobile part and one wired part in such a way that a user channel connection is established more quickly upon a connection request indicated by the mobile part or the wired part for the purpose of transmitting user data and, at the same time, due to market requirements, no synchronization pulses are sent by the wired part in the idle state, an initiating device of the communication system (for example, for an incoming call: base station; for an outgoing call: mobile part) sends, from an asynchronous idle state, synchronization pulses (SB) to all available physical resources. Due to the plurality of the sent, available synchronization pulses (SB), rapid synchronization is ensured because the probability is sufficiently increased thereby that a pulse will fall in the search window of a receiver.
