UE MBMS Access Information Acquisition Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In current Mobile Communication systems, User Equipment (UE) faces challenges in efficiently acquiring and managing Multimedia Broadcast/Multicast Service (MBMS) access information, leading to unnecessary energy consumption and resource utilization inefficiencies.
Innovation Solution
A method for UE to automatically control the acquisition of MBMS access information by receiving an MBMS access information message, generating a random number, and comparing it with a probability factor to determine if the corresponding procedure should be initiated or stopped, thereby reducing energy consumption and optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UE continuously acquires MBMS access information to ensure service availability, then service reliability is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic acquisition of MBMS access information by the UE, where the UE wakes up at predetermined intervals to check for new access information messages from the network, and enters idle state between intervals. This periodic mechanism ensures service availability when needed while minimizing energy consumption during idle periods.
2Loss of information
If UE acquires MBMS access information in all states to ensure complete information reception, then information completeness is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent applies different acquisition strategies based on the UE's current state. When the UE is in idle state, it acquires MBMS access information through listening to BCCH or PCCH channels. When in connected state, it receives information through dedicated signaling. This state-dependent approach ensures information completeness while optimizing resource utilization for each specific scenario.
3Speed
If UE monitors MBMS access information continuously to respond to network changes, then response speed is improved, but energy consumption increases
Solution Approach 1:
The UE monitors for MBMS access information messages at predetermined intervals rather than continuously. When a message is detected, the UE quickly processes it and responds appropriately. This periodic monitoring approach maintains adequate response speed to network changes while dramatically reducing energy consumption compared to continuous monitoring.

AI summary
The invention discloses a method for acquiring MBMS access information comprising: in a modification period, upon receiving an MBMS access information message transmitted from a network a UE initiating a corresponding procedure according to its state; if completing the corresponding procedure successfully, the UE stopping receiving a further MBMS access information messages; if not completing the corresponding procedure successfully the UE continuing acquiring further MBMS access information messages. The method facilitates the UE to automatically control MBMS access information acquiring procedure, and further reduces energy consumption of the UE to the maximum extent.
