gNB Paging Access Type Parameter for Heterogeneous Network Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in enabling efficient communication between mobile devices and disaggregated base stations, particularly in complex network scenarios involving multiple networks and components like centralized and distributed units in 3GPP, LTE, NR, and 5G networks.
Innovation Solution
The implementation of a method that involves a Next Generation Node-B (gNB) with a central unit (gNB-CU) and a distributed unit (gNB-DU), which decodes paging messages from an access management function entity and encodes paging messages for transmission to mobile devices, including an access type parameter to indicate the origin of the PDU session, facilitating communication across 3GPP and non-3GPP access types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile device communicates with a disaggregated base station including centralized and distributed units, then network flexibility and scalability are improved, but communication complexity and difficulty increase
Solution Approach 1:
The base station is divided into a centralized unit (CU) and a distributed unit (DU), allowing independent deployment and management of control functions and radio access functions. This segmentation enables network flexibility while managing complexity by separating concerns between centralized control and distributed execution.
Solution Approach 2:
The patent introduces an access type parameter as an intermediary element in paging messages to bridge communication between the disaggregated base station components and user equipment. This parameter mediates the indication of access type (3GPP or non-3GPP) through the paging procedure, simplifying the interaction in heterogeneous access scenarios.
2Productivity
If paging messages include access type parameter to indicate PDU session origin, then communication efficiency across different access types is improved, but message complexity increases
Solution Approach 1:
The access type parameter is designed to serve multiple functions within the paging message structure. It simultaneously indicates the origin of the PDU session (3GPP or non-3GPP access) and enables the network to route paging appropriately across heterogeneous access types, providing universal applicability without requiring separate messaging protocols.
Solution Approach 2:
The patent modifies the existing paging message by adding an access type parameter, changing the message structure to include additional information. This parameter change enables efficient differentiation between access types while maintaining compatibility with existing paging procedures, balancing enhanced functionality with minimal complexity increase.

AI summary
Embodiments of a Next Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configured with a gNB-CU and a gNB-DU. A first paging message for paging of the UE may be received at the gNB-CU from an access management function (AMF) entity. The first paging message may include: a paging identity of the UE; and a paging origin information element (IE) that indicates whether the paging of the UE is originated due to a protocol data unit (PDU) session from non-3GPP access. A second paging message to page the UE may be transmitted from the gNB-DU to the UE. The second paging message may include: the paging identity of the UE; and an access type parameter that indicates whether the paging of the UE is originated due to the PDU session from the non-3GPP access.
