Service-Specific Paging Configuration for 5G Network Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, such as LTE and 5G, face challenges in supporting diverse use-case characteristics and access requirements due to fixed paging cycles per cell, which can lead to inaccessible delays for time-sensitive services and paging collisions in multi-SIM scenarios.
Innovation Solution
The proposed solution involves transmitting multiple sets of paging configuration information by network nodes to communication nodes, allowing for service-type-specific paging configurations. This enables the selection of preferred paging configurations based on service types, mitigates paging collisions through 5G-STMSI reallocation, and allows manual selection of non-public networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed paging cycles per cell are used, then system simplicity is maintained, but service flexibility and time-sensitive access are degraded
Solution Approach 1:
The patent segments the paging configuration into multiple sets, each tailored to different service types (e.g., eMBB, URLLC, mMTC). The network node transmits multiple paging configuration sets to the communication node, allowing selection of appropriate configurations based on service requirements. This segmentation enables service-specific paging parameters without requiring complete system redesign.
Solution Approach 2:
The patent introduces dynamic paging configuration where the network node can transmit different paging configuration sets based on service type indicators. The communication node dynamically selects the appropriate paging configuration set according to the active service type, enabling flexible adaptation to different service requirements while maintaining system manageability through standardized selection mechanisms.
2Reliability
If single paging configuration is used, then network management is simplified, but paging collisions in multi-SIM scenarios increase
Solution Approach 1:
The patent segments paging resources by introducing service type-specific paging configurations with distinct parameters including different paging frames, paging occasions, and 5G-STMSI allocation schemes. This segmentation allows multi-SIM devices to operate on different paging configurations simultaneously, eliminating collisions while maintaining manageable network control through standardized configuration sets.
Solution Approach 2:
The patent introduces service type information as an intermediary parameter that mediates between multiple paging configurations. The network node uses service type indicators to select and transmit appropriate paging configuration sets, while communication nodes use these indicators to select corresponding configurations. This intermediary mechanism coordinates multi-SIM operations without requiring complex direct management of all possible configuration combinations.
3Loss of time
If service-type-specific paging configurations are implemented, then access delay for time-sensitive services is reduced, but information overhead increases
Solution Approach 1:
The patent applies local quality by providing different paging configuration parameters tailored to specific service types. Each paging configuration set contains service-optimized parameters such as shorter paging cycles for URLLC and longer cycles for mMTC. The network transmits multiple configuration sets with service type indicators, allowing communication nodes to select locally optimal configurations without requiring all nodes to process all configurations, thus reducing overall information overhead.
Solution Approach 2:
The patent implements preliminary action by pre-configuring multiple paging configuration sets with service type indicators before actual paging operations. The network node prepares and transmits these configuration sets in advance, allowing communication nodes to immediately select appropriate configurations when service type changes occur, eliminating configuration setup delays while managing overhead through reusable pre-defined configuration templates.
4Adaptability or versatility
If manual network selection is enabled, then network selection flexibility is improved, but device complexity and user burden increase
Solution Approach 1:
The patent implements dynamic network selection capability where the communication node can automatically select networks based on service type and configuration, or switch to manual selection mode when needed. The system dynamically adjusts between automatic and manual modes based on operational context, providing flexibility when required while maintaining simplicity during normal operations. This dynamic approach balances automation with user control without requiring constant manual intervention.

AI summary
Techniques are described for paging techniques. For example, a wireless communication method comprises transmitting, by a network node to a communication node, multiple sets of paging configuration information, where each set of paging configuration information includes a service type information that describes a type of network service, and where each set of paging configuration information includes one or more paging related information.
