Trunking Server Multicast Paging for LTE Access Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trunking communication systems face challenges in access performance and efficiency, particularly in handling broadband services like video calls and picture transmission, due to one-by-one paging of terminals and unicast downlink service delivery in LTE networks.
Innovation Solution
A trunking communication system comprising a trunking management server with a call service control module and a media gateway, integrated with an access network that includes an MME, eNodeB, MBMS gateway, and PDN gateway, enabling multicast communication and efficient resource allocation for improved access performance and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If terminals in a group are paged in a one-by-one paging manner, then the existing trunking communication system can be maintained, but access performance and efficiency are bad
Solution Approach 1:
The patent combines multiple individual paging operations into a single group-based paging operation. Instead of paging each terminal separately in the group, the system pages all terminals in the group simultaneously using a group identifier, thereby improving access efficiency and reducing access time.
Solution Approach 2:
The patent implements a universal paging mechanism that can handle both individual terminal paging and group terminal paging. The paging system is enhanced to support group-based paging as a multi-functional capability, allowing efficient access to multiple terminals through a single paging message.
2Quantity of substance
If the downlink service is sent in a unicast manner, then the existing trunking communication system can be maintained, but occupancy on downlink channel resources in a system is increased
Solution Approach 1:
The patent merges multiple unicast downlink transmissions into a single multicast transmission. Instead of sending separate unicast messages to each terminal in the group, the system uses a single multicast message that can be received by multiple terminals simultaneously, thereby reducing downlink channel resource occupancy and increasing system capacity.
Solution Approach 2:
The patent changes the transmission parameter from unicast to multicast mode. This parameter change allows the system to efficiently deliver downlink services to multiple terminals using a single transmission, optimizing channel resource utilization and enhancing system capacity.
3Adaptability or versatility
If conventional trunking communication system is used, then basic calling function can be provided, but demands of various broadband services such as video call and picture transmission cannot be satisfied
Solution Approach 1:
The patent enhances the trunking communication system to provide multi-functional support for various broadband services. The system is designed to handle not only basic voice calling but also video calls, picture transmissions, and other data-intensive services by implementing group-based paging and multicast capabilities that efficiently support diverse service types.

AI summary
The present disclosure relates to trunking communication systems, servers, access networks, and trunking communication methods. One example system includes a trunking management server and an access network. The trunking management server includes a trunking call service control module and a connected trunking call media gateway module. The trunking call media gateway module is configured to receive service data sent through the access network by a trunking UE, and forward the service data according to a communication type of the service data for implementing user plane communication of the trunking UE. The trunking call service control module is configured to receive a communication request sent through the access network by a trunking UE, and perform call control and bearer management on the trunking UE according to a communication type of the communication request for implementing control plane communication of the trunking UE.
