LTE Base Station GTCH Resource Scheduling for Trunking QoS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trunking communication systems, based on 2G and 3G technologies, struggle to meet the increasing demands for broadband multimedia services with Quality of Service (QoS) assurance, leading to unsatisfied user requirements and reduced user experience.
Innovation Solution
A method and device for processing trunking services using the Long Term Evolution (LTE) system, where a base station generates and transmits scheduling information for Global Trunking Channel (GTCH) resources, including allocation of C-RNTI, periodically reported resources, uplink synchronization, Group-RNTI, and Hybrid Automatic Repeat Request (HARQ) resources, to User Equipments (UEs), utilizing the Physical Downlink Control Channel (PDCCH) and Physical Uplink Control Channel (PUCCH) or Physical Random Access Channel (PRACH).
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing trunking communication systems (2G/3G) are used, then narrow band voice services and low rate data service are provided, but broadband multimedia services with QoS assurance cannot be met
Solution Approach 1:
The patent changes the fundamental system parameters by migrating from 2G/3G trunking systems to LTE technology. This enables broadband multimedia services with enhanced data rates, bandwidth, and QoS assurance while maintaining trunking service functionality through adaptive resource allocation and scheduling mechanisms
2Adaptability or versatility
If LTE system is used for trunking service, then broadband multimedia services with large bandwidth and QoS assurance are provided, but scheduling complexity increases
Solution Approach 1:
The patent segments the scheduling process into distinct components: resource allocation, scheduling decision-making, and information transmission. By separating these functions and using standardized LTE scheduling mechanisms, the system manages broadband service complexity while maintaining efficient resource utilization
Solution Approach 2:
The patent applies universal LTE scheduling principles to trunking services, using the same scheduling framework for both traditional trunking traffic and broadband multimedia services. This multi-functional approach reduces overall system complexity by avoiding separate scheduling mechanisms
3Ease of operation
If GTCH resources are scheduled for trunking service in LTE system, then user experience is improved, but transmission reliability must be ensured
Solution Approach 1:
The patent implements feedback mechanisms through HARQ (Hybrid Automatic Repeat Request) and scheduling information transmission. The base station transmits scheduling information to UEs, and acknowledgment feedback ensures reliable delivery, allowing retransmission if needed while maintaining smooth user experience

AI summary
A method and a device for processing trunking service, a base station and user equipment are disclosed. The method comprises that: a base station generates scheduling information used for scheduling Global Trunking Channel (GTCH) resources for performing a trunking service with one or more User Equipments (UEs) based on a Long Term Evolution (LTE) system; and the base station transmits the generated scheduling information to the one or more UEs. The present invention solves the problems that a trunking communication system cannot satisfy user's service requirements and the user experience is reduced, thereby achieving the effects of satisfying user's trunking service requirements based on the LTE system and improving the user experience.
