MBMS Terminal State Control for Network Load Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The network becomes overloaded due to an excessive number of user equipment (UEs) receiving multimedia broadcast/multicast services (MBMS) in the RRC_CONNECTED state.
Innovation Solution
A terminal state processing method where a network side device indicates to terminals receiving MBMS services to enter a specified RRC state or specifies a time duration for receiving MBMS services in that state, thereby reducing the load when the network is overloaded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminals receive MBMS service in RRC_CONNECTED state, then service quality is improved, but network load increases
Solution Approach 1:
The patent applies dynamics by enabling terminals to dynamically switch between RRC_CONNECTED and RRC_IDLE states based on network load conditions. The network side device controls terminals to enter RRC_IDLE state when overloaded, allowing flexible adaptation to varying network conditions and resolving the contradiction between maintaining service quality and reducing network load.
Solution Approach 2:
The patent changes the RRC state parameter from a fixed connection state to a dynamic state that can transition between CONNECTED and IDLE. This parameter change allows the system to adjust the number of active terminals based on network capacity, thereby balancing service quality and network load.
2Stability of the object's composition
If terminals remain in RRC_CONNECTED state for MBMS service, then connection stability is maintained, but network overload occurs
Solution Approach 1:
The patent implements feedback by having the network side device monitor network load conditions and send control instructions to terminals. When the network is overloaded, the network side device instructs terminals to switch to RRC_IDLE state, creating a closed-loop control system that maintains connection stability while preventing network overload.
Solution Approach 2:
The system transitions from a static connection model to a dynamic one where terminals can switch states based on real-time network conditions. This dynamic behavior allows the system to maintain stability during normal operation while reducing load during peak periods.

AI summary
This disclosure provides a terminal state processing method, a device and a medium. The method includes: in a case that a network is overloaded due to an excessive quantity of terminals receiving an MBMS service in an RRC_CONNECTED state, indicating, by a network side device, that a terminal receiving the MBMS service is to enter a specified RRC state, and/or indicating, by the network side device, a time duration for a terminal to receive the MBMS service in the specified RRC state. The terminal enters the specified RRC state in accordance with the indication, and/or receives the MBMS service in the specified RRC state during the indicated time duration.
