Slice-Specific Grouped Paging for 5G Network Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G wireless networks, the large number of devices creates significant paging overhead for base stations, and network slicing introduces varying service requirements across different user equipment (UE) groups, necessitating efficient paging solutions to manage resources effectively.
Innovation Solution
The implementation of slice-specific grouped paging, where each slice-specific paging group is identified by a unique identifier and receives dedicated downlink control information and paging messages, allowing for separate paging operations and data transmission within the same message, reducing overhead and signaling requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional paging methods are used in 5G networks with network slicing, then all user equipment must be paged individually through separate signaling messages, but this creates excessive paging overhead and consumes unnecessary network resources when multiple UEs belong to the same slice and have similar service requirements
Solution Approach 1:
The patent merges multiple individual paging operations into a single group paging message. User equipment belonging to the same slice-specific paging group receives a unified paging message that contains group identification information, allowing the network to page multiple UEs simultaneously rather than sending separate paging messages to each UE individually.
Solution Approach 2:
The patent segments the user equipment population into distinct slice-specific paging groups based on their network slice affiliations. Each paging group is identified by a unique group ID that corresponds to specific slice identifiers, enabling targeted group paging operations for UEs with similar service requirements while maintaining the ability to page individual UEs when necessary.
2Adaptability or versatility
If network slicing is implemented to support diverse service requirements, then different UE groups need customized paging configurations, but this increases system complexity in managing multiple paging groups and their identifiers
Solution Approach 1:
The patent creates a universal paging mechanism that handles both individual UE paging and group UE paging through a unified framework. The same paging message structure and transmission procedures are used whether paging a single UE or a group of UEs, with the distinction made through the presence of group identification information. This multi-functional approach supports diverse service requirements without requiring separate paging mechanisms for each scenario.
Solution Approach 2:
The patent performs preliminary classification of user equipment into slice-specific paging groups during initial registration or configuration phases. Group identifiers are pre-assigned to UEs based on their network slice memberships, so that when paging is needed, the network can immediately identify and page the appropriate groups without performing complex real-time classification, thereby reducing paging management complexity.

AI summary
A technique includes receiving, by a first user device within a wireless network, an indication that the wireless network supports slice-specific grouped paging for at least a first slice-specific paging group, wherein the first user device is a member of the first slice-specific paging group; decoding, by the first user device, a received downlink control information that has been directed to the first slice-specific paging group to obtain scheduling information for a paging message for the first slice-specific paging group; receiving, by the first user device from the base station based on the scheduling information, the paging message for the first slice-specific paging group; and receiving, by the first user device, data based on the paging message.
