UE Type Filtering for Paging Signaling Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication systems face inefficiencies in signaling overhead between the core network and base stations due to the lack of clear indication of which types of user equipment (UE) are allowed to reside on or access the base stations, leading to unnecessary paging messages being sent.
Innovation Solution
The method involves exchanging information between communication nodes to determine the types of UE not allowed to reside on or access specific base stations, allowing the core network to selectively send paging messages based on the access capabilities of the base stations, thereby reducing unnecessary signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the core network sends paging messages to all base stations in a TA list without filtering by UE type, then the paging coverage is complete, but the signaling overhead increases and communication efficiency decreases
Solution Approach 1:
The base station preliminarily determines and reports to the core network which UE types are not allowed to reside on or access the base station before the paging process. This preliminary filtering action enables the core network to pre-filter paging messages, avoiding unnecessary signaling while maintaining complete paging coverage for allowed UE types.
Solution Approach 2:
The invention extracts the UE type restriction information from the base station and transmits it to the core network. This extracted information is then used by the core network to filter out paging messages for disallowed UE types, reducing signaling overhead while preserving the reliability of paging for authorized users.
2Productivity
If the base station does not provide UE type access capability information, then the device complexity is low, but the core network cannot selectively send paging messages leading to wasted resources
Solution Approach 1:
The base station performs a preliminary determination of which UE types are not allowed to access it and reports this information to the core network in advance. This preliminary action enables the core network to efficiently filter paging messages without requiring complex real-time processing, thus improving paging efficiency with minimal added complexity.
Solution Approach 2:
The base station provides feedback information to the core network about its UE type access capabilities. This feedback mechanism enables the core network to adapt its paging strategy by selectively sending pages only to allowed UE types, improving resource utilization without requiring complex dynamic control mechanisms.

AI summary
An information transmission method is performed by a first communication node. A first communication node sends a first information to a second communication node, in which the first information is at least used for determining a type of a user equipment (UE) that is not allowed to reside on the first communication node or to reside in a cell of the first communication node.
