User Equipment Paging Group Determination via Core and Access Network Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, determining a user paging group is challenging due to the lack of a specific scheme for negotiation between the network and user equipment (UE), leading to inconsistency in understanding between the network and UE about the user group.
Innovation Solution
A method and apparatus for determining a user paging group, where the UE receives and determines a paging group based on parameters sent by the network side, including a first paging group parameter determined by the core network and a second paging group parameter determined by the access network, ensuring consistency through negotiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network and UE negotiate on the user group to achieve consistency, then the understanding consistency between network and UE is improved, but the complexity of the negotiation scheme increases
Solution Approach 1:
The patent segments the paging group determination into two independent parts: a first paging group parameter determined by the core network device and a second paging group parameter determined by the access network device. This segmentation allows each network element to independently determine its parameter without complex mutual negotiation, while the UE can determine the paging group based on at least one of these parameters, thus maintaining consistency without increasing scheme complexity
Solution Approach 2:
Instead of having the network and UE negotiate to reach consensus on the paging group, the patent inverts the approach by having the network devices independently determine parameters that the UE then uses to determine the paging group. This eliminates the need for negotiation while ensuring consistency, as the UE derives the paging group from network-determined parameters
2Device complexity
If no specific negotiation scheme exists between network and UE, then the system simplicity is maintained, but the ability to effectively determine user paging group deteriorates
Solution Approach 1:
The patent applies preliminary action by having the core network device and access network device determine the first and second paging group parameters in advance, before the UE needs to determine the paging group. These pre-determined parameters are then provided to the UE, which uses them to determine the paging group. This eliminates the need for complex negotiation while ensuring effective and timely paging group determination

AI summary
A method for determining a user paging group is performed by a user equipment (UE), and includes: receiving at least one of a first paging group parameter or a second paging group parameter sent by a network side device, wherein the first paging group parameter is determined by a core network device, and the second paging group parameter is determined by an access network device; and determining a paging group of the UE based on the at least one of the first paging group parameter or the second paging group parameter.
