Solution Overview
Problem
In multi-operator core network scenarios, network devices fail to recognize that multiple UEs associated with a single terminal device, leading to unnecessary waste of radio resources and increased power consumption due to redundant operations.
Innovation Solution
A network device determines that UEs in different cells are associated with a single terminal device and enables the device to perform specific operations while preventing redundant actions, such as measuring or transmitting reference signals and measurement reports.

Engineering Contradiction Analysis
1Ease of operation
If the network device treats each SIM-associated UE as a separate entity, then the network device can independently manage each UE's radio resources, but this results in unnecessary waste of radio resources and increased power consumption due to redundant operations
Solution Approach 1:
The patent merges the management of multiple UEs associated with the same physical terminal device into a single unified management approach. The network device identifies that multiple UEs (each associated with a different SIM) belong to the same physical device and combines their radio resource management, so that reference signals and measurement reports are shared across all UEs rather than being duplicated. This eliminates redundant operations and reduces power consumption while maintaining independent management capabilities.
2Reliability
If the network device allocates radio resources for reference signals and measurement reports to each UE separately, then each UE can independently perform measurements, but this causes unnecessary waste of radio resources
Solution Approach 1:
The patent combines radio resource allocation for multiple UEs associated with the same physical terminal device. Instead of allocating separate reference signals and measurement report resources to each UE, the network device allocates shared resources that can be used by all UEs. This merging approach maintains measurement reliability while significantly reducing the quantity of radio resources consumed, as the same physical device performs measurements once and shares the results across all its associated UEs.
3Device complexity
If the network device is not aware that multiple UEs belong to one terminal device, then the network device can simplify its tracking of UE identities, but this leads to redundant operations and inefficient resource utilization
Solution Approach 1:
The patent applies preliminary action by having the terminal device provide identification information upfront that links multiple UEs to the same physical device. The network device uses this pre-provided information to establish the association between multiple UEs and their shared physical terminal. This preliminary identification enables the network device to optimize resource allocation and eliminate redundant operations, improving productivity without significantly increasing the complexity of UE identity tracking.
