CountingResponse Message Security Activation in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the lack of specified timing for sending a CountingResponse message leads to incorrect counting procedures and inefficient radio resource utilization due to malicious UEs and incorrect handling during RRC procedures, particularly when security is not activated and during handovers between eNBs.
Innovation Solution
A method where a UE activates security with the network before transmitting a CountingResponse message and only sends it after completing RRC procedures, and the network ignores unauthenticated messages, ensuring accurate counting and efficient resource allocation by authenticating responses and handling handovers correctly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a UE sends a CountingResponse message before security activation, then the response can be transmitted early, but malicious UEs can send unauthenticated messages to confuse the network and waste radio resources
Solution Approach 1:
The patent applies preliminary action by requiring security activation to be completed before the UE sends the CountingResponse message. This ensures that authentication and encryption are established in advance, preventing malicious UEs from sending unauthenticated messages while still allowing timely response transmission once security is ready.
2Ease of operation
If the network broadcasts MBMS service to all UEs, then all UEs can receive the service, but radio resources are wasted when fewer UEs actually need the service
Solution Approach 1:
The patent uses feedback through the CountingResponse message mechanism, where UEs indicate their interest in MBMS services. The network collects these responses to determine the actual number of interested UEs, then decides whether to broadcast or unicast the service accordingly. This feedback loop enables dynamic resource allocation that matches actual demand.
3Productivity
If the network performs counting procedure without security protection, then the procedure can be completed quickly, but the counting results can be manipulated by malicious UEs
Solution Approach 1:
The patent applies preliminary action by establishing security protection through security activation before the counting procedure begins. This ensures that CountingResponse messages are authenticated and encrypted, preventing manipulation by malicious UEs while maintaining counting procedure efficiency through pre-established security contexts.
4Loss of time
If a UE sends CountingResponse during RRC procedure, then the response can be sent promptly, but the network cannot properly handle the message without knowing the UE's RRC status
Solution Approach 1:
The patent applies preliminary action by requiring the UE to complete the RRC procedure before sending the CountingResponse message. This ensures that the network has full knowledge of the UE's RRC status and can properly handle the message without ambiguity, while still allowing timely response once the RRC procedure is complete.
