Uplink Position Signal Addressing in Virtualized Ultra Dense Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Ultra Dense Networks (UDNs), the complexity of mobility management and the need for efficient addressing of user equipment (UE) arise due to cell virtualization, where conventional methods for identifying and addressing UE are no longer applicable, necessitating a new scheme to manage and address UE in a virtualized environment.
Innovation Solution
The proposed method involves the UE determining and transmitting an uplink position signal carrying its identifier to the network side, allowing the network to determine and address the UE based on this identifier, eliminating the need for the UE to identify individual cells and enabling efficient service provision in virtualized UDNs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cell virtualization is adopted in UDN to enable UE to manage and move in larger virtual regions, then mobility management efficiency is improved, but conventional addressing methods become inapplicable and device complexity increases
Solution Approach 1:
The patent extracts the cell identification requirement from the addressing system by using uplink position signals that carry UE identifiers independent of cell identifiers. This separates the positioning function from the cell structure, allowing virtualization without requiring UE to identify individual cells.
Solution Approach 2:
The uplink position signal serves multiple functions: it carries UE identification, enables positioning, and supports addressing in virtualized networks. This multi-functional approach replaces multiple separate mechanisms (cell identification, positioning, addressing) with a unified signal.
2Reliability
If UE is required to identify individual cells in UDN, then conventional addressing methods work, but the large number of access nodes and complex network structure make mobility management inefficient
Solution Approach 1:
The patent segments the addressing function from the cell structure by using UE identifiers in uplink position signals rather than relying on cell identifiers. This allows the network to address UEs directly without requiring UE to process cell identification information.
3Adaptability or versatility
If cell identifier and region information change significantly during cell virtualization, then UE can move in virtual regions, but UE cannot efficiently transmit data without cell identification
Solution Approach 1:
The uplink position signal acts as an intermediary that carries UE identification information to the network side without requiring UE to interpret cell identifiers or region information. The network uses this signal to determine addressing information and route data efficiently.

AI summary
An addressing method is provided, including: determining, by a UE, configuration information of an uplink position signal; and transmitting, by the UE, the uplink position signal carrying an identifier of the UE to a network side in accordance with the determined configuration information, to enable the network side to determine addressing information of the UE in accordance with the identifier of the UE, and address the UE in accordance with the identifier and the addressing information of the UE in the case that it is necessary to address the UE.
