H(e)NB and L-GW Interface Establishment for UE Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing stand-alone local H(e)NB network lacks effective methods to support session continuity and dynamic configuration for mobility of User Equipment (UE), as well as secure connection establishment between separated H(e)NB and L-GW entities.
Innovation Solution
The solution involves physically separating H(e)NB and L-GW entities in the stand-alone local H(e)NB network, enabling them to share self-information and establish secure connections using DHCP messages, broadcast mechanisms, or an H(e)NB Management System (HMS) to facilitate interface formation and mobility support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If H(e)NB and L-GW are unified and jointly operated in a collocated local network, then the structure is simple, but it has difficulty in satisfying the mobility of the UE
Solution Approach 1:
The patent divides the unified H(e)NB-L-GW entity into separate H(e)NB and L-GW entities that can be independently deployed and managed. This segmentation allows the network to maintain simplicity when collocated while enabling mobility support when separated, resolving the contradiction between structural simplicity and mobility adaptability
2Adaptability or versatility
If H(e)NB and L-GW are separated in a stand-alone local network, then UE mobility is supported, but the entities have difficulty in discovering each other and establishing connections dynamically
Solution Approach 1:
The patent implements self-service mechanisms where H(e)NB and L-GW entities automatically discover each other and establish connections without manual configuration. The entities use standardized protocols to autonomously perform entity discovery, interface establishment, and parameter configuration, making the system easy to operate while maintaining mobility support
3Adaptability or versatility
If H(e)NB and L-GW are separated entities, then mobility of UE is supported, but there is no effective method for session continuity and secure connection establishment
Solution Approach 1:
The patent introduces standardized protocols and interface specifications as intermediaries between separated H(e)NB and L-GW entities. These intermediaries ensure secure authentication, encrypted communication, and session continuity during mobility events, resolving the contradiction between mobility support and connection reliability

AI summary
Disclosed is an apparatus and a method of establishing an interface between entities in a local network. A stand-alone local H(e)NB network has a structure in which one or more H(e)NBs are separated from one or more L-GWs in order to support mobility of a user equipment. The one or more H(e)NBs or the one or more L-GWs provide an information management device with information necessary for establishing an interface and receive information necessary for establishing the interface with a target entity as a response to the provision of the information. The one or more H(e)NBs or the one or more L-GWs establish the interface with the target entity based on the received information.
