Service Switching Between Broadcast and Unicast in 5G Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G systems, terminals face challenges in maintaining service continuity when moving out of broadcast areas or vice versa, requiring efficient switching between broadcast and unicast services.
Innovation Solution
A method for service switching is implemented, where terminals and network devices can switch from a first service (e.g., broadcast) to a second service (e.g., unicast) based on preset conditions, such as moving out of a broadcast area or detecting the availability of broadcast services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a terminal uses broadcast service within a broadcast area, then service efficiency is improved through point-to-multipoint transmission, but service continuity deteriorates when the terminal moves out of the broadcast area
Solution Approach 1:
The patent implements dynamic service switching between broadcast and unicast modes based on terminal location. The terminal monitors its position relative to broadcast areas and automatically switches service types to maintain continuity, making the system adaptive rather than static.
Solution Approach 2:
The patent introduces a service switching mechanism as an intermediary layer between the terminal and network services. This switching mechanism detects broadcast area boundaries and coordinates transitions between broadcast and unicast services to ensure seamless continuity.
2Reliability
If a terminal switches from broadcast service to unicast service when moving out of broadcast area, then service continuity is maintained, but system complexity increases due to switching control requirements
Solution Approach 1:
The terminal autonomously determines when to switch between broadcast and unicast services by monitoring its own location relative to broadcast areas. The switching decision is made self-service at the terminal without requiring complex centralized control, reducing overall system complexity.
Solution Approach 2:
The terminal pre-configures switching criteria and thresholds before entering broadcast areas. When location conditions are met, the switching action is triggered automatically based on pre-established rules, simplifying the control logic during actual service operation.
3Reliability
If a terminal remains in unicast service when moving into a broadcast area, then service continuity is maintained, but energy consumption increases due to loss of broadcast efficiency
Solution Approach 1:
The service mode dynamically adapts to terminal location, switching from unicast to broadcast when entering broadcast areas. This dynamic adjustment optimizes energy consumption by leveraging the efficiency of broadcast transmission when available, rather than maintaining static unicast connections.

AI summary
Disclosed are a service switching method, a terminal and a network device. The method comprises: when a terminal receives data of a first service, if the terminal determines that a present condition is satisfied, then the terminal switches to receiving data of a second service. The preset condition comprises: the condition of the terminal stopping the first service, and/or the condition of receiving the data of the second service.
