Logical Base Transceiver Timeslot Remapping for BSC Resource Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional base transceiver stations (BTS) often underutilize resources when deploying small-scale BTSs, as each BTS typically requires multiple transceivers, leading to unused capacity in the base station controller (BSC), especially when each small-scale BTS is configured with only one transceiver.
Innovation Solution
Implementing a single logical BTS to serve multiple physical BTSs through timeslot and frequency remapping, allowing a single logical transceiver to manage multiple physical transceivers with fewer usable timeslots, thereby optimizing resource utilization across the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If each small-scale BTS is configured with only one transceiver, then device complexity and deployment cost are reduced, but resource utilization of the BSC deteriorates due to underutilization of transceiver capacity
Solution Approach 1:
The patent merges multiple physical BTSs into a single logical BTS, allowing the BSC to manage them as one entity. This combining approach enables the BSC to pool transceiver resources across multiple physical locations, thereby improving overall resource utilization while keeping individual BTS configurations simple.
Solution Approach 2:
The logical BTS structure provides multi-functionality by enabling a single logical entity to serve multiple physical locations simultaneously. The BSC's transceiver resources are made universal, capable of serving different physical BTSs through the logical abstraction, thus improving resource utilization without increasing individual BTS complexity.
2Area of stationary object
If multiple physical BTSs are deployed to serve different geographic areas, then service coverage area is expanded, but management complexity increases due to multiple independent BTS configurations
Solution Approach 1:
The patent segments the BTS function into logical and physical layers. Multiple physical BTSs are segmented as separate deployment units for geographic coverage, while logically they are combined into a single manageable entity. This segmentation allows expanded coverage without proportional increase in management complexity.
Solution Approach 2:
The logical BTS acts as an intermediary between the BSC and multiple physical BTSs. It provides a unified management interface to the BSC while handling the complexity of coordinating multiple physical locations, thereby expanding service area without increasing top-level management complexity.
3Adaptability or versatility
If a BSC supports maximum number of BTSs (300) with minimum transceivers each (1), then adaptability to small-scale deployments is improved, but overall network capacity is reduced due to underutilization of BSC transceiver capacity
Solution Approach 1:
The patent introduces a logical dimension to the BTS architecture, creating a two-layer structure (logical and physical). This dimensional change allows the system to achieve both deployment flexibility at the physical level and capacity efficiency at the logical level, resolving the contradiction between adaptability and total capacity.
Solution Approach 2:
The patent changes the organizational parameter of BTS from physical-count based to logical-entity based. By changing how BTS are grouped and managed (from individual physical units to logical consolidations), the system maintains deployment flexibility while improving transceiver capacity utilization through statistical multiplexing.

AI summary
Using a single logical base transceiver to serve multiple physical locations is disclosed. A call traffic associated with a call associated at a mobile network with an assigned timeslot of a logical base transceiver is received. A timeslot with which the call traffic is associated is remapped from the assigned timeslot to a serving timeslot being used at a serving physical base transceiver to facilitate the call, in the event the call traffic comprises inbound call traffic being sent into the mobile network from the serving physical base transceiver, or from the serving timeslot to the assigned timeslot in the event the call traffic comprises outbound call traffic being sent from the mobile network to the serving physical base transceiver.
