UE PLMN Matching for MBMS Counting Response Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, user equipment (UE) often transmit unnecessary MBMS counting response messages, leading to inefficiencies, particularly when the request message is not associated with the registered Public Land Mobile Network (PLMN) identifier.
Innovation Solution
The UE receives system information including a specific PLMN identifier and only transmits a response message if the PLMN identifier matches the registered PLMN, ensuring that the MBMS counting response is sent only when the request is associated with the user's registered network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE transmits MBMS counting response messages for all received request messages, then the network receives complete counting information, but unnecessary messages are transmitted when the request is not associated with the registered PLMN
Solution Approach 1:
The UE performs preliminary verification by checking whether the PLMN identifier in the received MBMS counting request message matches its registered PLMN identifier before transmitting the response message. This preliminary action prevents unnecessary message transmissions and conserves network resources while ensuring that only relevant counting information is reported.
2Productivity
If the UE checks PLMN identifier before transmitting response, then network efficiency is improved, but the device complexity increases
Solution Approach 1:
The invention changes the parameter verification approach by comparing the PLMN identifier parameter in the received request message with the stored registered PLMN identifier. This simple parameter comparison operation achieves efficient message filtering without requiring complex processing logic, thus improving network efficiency while minimizing device complexity.

AI summary
A user equipment (UE) in a wireless communication system is described. The UE includes a receiver, a processor and a transmitter. The receiver is configured to receive a multimedia broadcast multicast service (MBMS) counting request message through a first cell of a network. The processor is configured to determine whether or not to transmit a MBMS counting response message in response to the MBMS counting request message. The transmitter is configured to transmit the MBMS counting response message if it is determined to transmit the MBMS counting response message. The processor is further configured to determine to transmit the MBMS counting response message if a registered-public land mobile network (R-PLMN) identity is included in system information broadcast by the network.
