Base Station Controller Capacity via Shared Time Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio communication networks face challenges in increasing channel capacity, particularly due to asymmetrical data and voice traffic demands, leading to wasted resources and reduced network performance, especially during peak usage events like major events or festivals, where many users attempt to access the network simultaneously, resulting in co-channel and adjacent channel interferences.
Innovation Solution
The implementation of a base station controller that utilizes shared training sequences and time slots on the same carrier frequency within a cell, allowing multiple users to share the same channel by allocating unused time slots and selecting different training sequences for new connections, thereby increasing network capacity without requiring additional hardware resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If more traffic channels are allocated to meet higher data throughput demand on downlink, then data service capacity is improved, but network resources are wasted due to asymmetrical UL/DL usage
Solution Approach 1:
The patent merges voice and data traffic handling by allowing data calls to occupy both uplink and downlink resources simultaneously, enabling dual transfer mode operation. This combines previously separate resource allocation pathways into a unified framework that efficiently utilizes asymmetrical bandwidth
Solution Approach 2:
The system dynamically adjusts resource allocation based on traffic type and direction. Data calls can flexibly use both UL and DL resources when needed, while voice calls use traditional pairing, allowing the network to adapt resource distribution to actual demand patterns rather than following fixed allocation rules
2Adaptability or versatility
If UL resources are allocated for new voice call users, then voice service availability is improved, but resources are wasted due to lack of paired DL resources
Solution Approach 1:
The system allows data calls to self-allocate both uplink and downlink resources independently without requiring traditional voice call pairing mechanisms. This self-service approach eliminates the bottleneck where UL resources remain idle waiting for DL pairing, as data traffic can immediately utilize allocated resources in both directions
3Productivity
If time slots are fully utilized for data transmission, then channel capacity is improved, but time for UEs to scan neighbor cells and monitor performance is reduced
Solution Approach 1:
The system implements periodic monitoring opportunities within the time slot structure, allowing UEs to periodically scan neighbor cells and report performance metrics while maintaining continuous data transmission. This periodic action ensures call stability through regular network monitoring without significantly reducing overall channel capacity

AI summary
The present patent application improves DARP by allowing multiple users on one time slot (MUROS). It comprises means and instructions for sharing signals on a single channel, comprising setting up a new connection, allocating a new time slot if there is an unused time slot on a channel frequency, selecting an used time slot for the new connection to share with an existing connection if there is not an unused time slot on the channel frequency, and selecting a different training sequence code for the new connection if the used time slot on the channel frequency has been selected for the new connection to share with an existing connection. Other aspects, embodiments, and features are also claimed and described.
