Fog-Resource Solicitation in Fog-RAN
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fog computing systems face challenges in efficiently managing and allocating resources, particularly in 5G networks, where wireless transmit/receive units (WTRUs) need to dynamically join or leave Fog Radio Access Networks (RAN) based on resource availability and location, without causing significant battery drain or network congestion.
Innovation Solution
A method where WTRUs receive Fog-Resource Solicitations through paging messages, allowing them to accept or decline resource allocation requests, and trigger connection releases, with the option to ignore solicitations if resources are not available, thereby optimizing resource usage and reducing battery consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If WTRUs continuously monitor and respond to Fog-Resource Solicitations, then resource allocation efficiency is improved, but battery consumption increases
Solution Approach 1:
The system dynamically adjusts WTRU connection states based on resource solicitation needs. WTRUs transition between idle and connected states depending on whether they are being solicited for fog resources, allowing the system to optimize resource allocation while minimizing battery consumption by keeping devices in low-power idle mode when not needed.
Solution Approach 2:
The network sends Fog-Resource Solicitation messages to WTRUs in idle mode, creating a feedback mechanism where resources are only activated when explicitly requested. This allows efficient resource allocation on-demand while avoiding continuous battery drain from maintaining active connections for all WTRUs.
2Adaptability or versatility
If WTRUs establish connections frequently to respond to solicitations, then resource management flexibility is improved, but network congestion increases
Solution Approach 1:
WTRUs perform measurements and evaluate resource availability in advance before establishing connections. The system prepares potential fog resources by having WTRUs monitor and report their capabilities while in idle mode, so when a solicitation arrives, the connection can be quickly established with pre-validated resource information, reducing unnecessary connection attempts and network traffic.
3Productivity
If WTRUs in idle mode are solicited for fog resources, then resource utilization is improved, but connection establishment complexity increases
Solution Approach 1:
The connection establishment process is segmented into distinct phases: initial idle mode monitoring, solicitation reception, measurement evaluation, and conditional connection establishment. This segmentation allows the system to manage complexity by breaking down the resource solicitation process into manageable steps, where WTRUs only proceed to full connection establishment when specific conditions are met.

AI summary
Methods, apparatuses, systems, etc., directed to resource solicitation for Fog Radio Access Network (RAN) are disclosed herein. For some embodiments, a wireless transmit receive unit (WTRU) may receive a Fog-Resource Solicitation, for example included in a paging message, for joining a Fog Radio Access Network (RAN) platform (e.g., soliciting resources). The WTRU may accept or decline the Fog-Resource Solicitation, for example, based on any of the solicited resources and the WTRU status. In case the WTRU accepts the fog-Resource Solicitation, the WTRU may establish a connection to the RAN for indicating an acceptance of the Fog-Resource Solicitation. In case the WTRU declines the Fog-Resource Solicitation, the WTRU may ignore the Fog-Resource Solicitation or respond to the Fog-Resource Solicitation by establishing a connection to the RAN, indicating a declination of the solicitation. For some embodiments, a WTRU may trigger sending a RRC-Connection Release Request to e.g., terminate the WTRU's connection to the network. The WTRU may transmit an information indicating the reasons why the WTRU is disconnecting from the network.
