Dynamic Prioritized Data Transmission in Radio Access Network Attach
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current attach procedure for user equipment (UE) in radio access networks (RANs) introduces latency and inefficiently utilizes resources, causing delays in data packet transmission and reception, as it reserves computing and networking resources for over-the-air signaling, preventing data packets from being transmitted or received during the attach process.
Innovation Solution
Implementing dynamic prioritized transmission and receipt of data packets by providing UE with resource information during release from the RAN, allowing for faster re-attachment and data transmission/reception by optimizing resource allocation and encryption configurations, and using signal strength thresholds to determine suitable attachment conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the current attach procedure reserves resources for over-the-air signaling, then signaling reliability is improved, but data packet transmission latency increases and resource utilization efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by performing authentication and resource allocation during the release phase before the attach procedure begins. The UE receives resource information and authentication credentials in advance, so that when the attach procedure is initiated, these preliminary actions have already been completed, allowing data packets to be transmitted without waiting for the traditional attach signaling sequence.
Solution Approach 2:
The patent segments the attach procedure into distinct phases: authentication (completed during release), resource allocation (completed during release), and data transmission (can begin immediately). This segmentation allows different functions to be performed at different times, enabling data transmission to proceed independently of the signaling completion status.
2Reliability
If the current attach procedure is used for transmission of signaling-related data only, then signaling function reliability is improved, but resource utilization efficiency deteriorates due to wasted computing and networking resources
Solution Approach 1:
The patent implements multi-functionality by enabling the attach procedure to serve dual purposes: traditional signaling functions and data packet transmission. By allowing data packets to be transmitted during the attach procedure using pre-allocated resources, the system makes the attach procedure universal, capable of handling both signaling and data traffic simultaneously, thereby improving resource utilization efficiency without compromising signaling reliability.
Solution Approach 2:
The patent merges signaling operations and data transmission operations into a unified process. Instead of separating signaling completion as a prerequisite for data transmission, the system combines these functions so that data packets can be transmitted concurrently with attach signaling, utilizing the same radio resources and processing paths for both purposes.
3Speed
If resource information is provided during release for faster re-attachment, then data transmission speed is improved, but device complexity increases due to additional authentication and resource management requirements
Solution Approach 1:
The patent applies self-service by enabling the UE to autonomously utilize pre-allocated resources during re-attachment without requiring complex real-time authentication or resource negotiation. The UE stores authentication credentials and resource information locally, and can independently initiate data transmission using these stored parameters, reducing the complexity of real-time resource management while maintaining fast transmission speeds.
Data Source
AI summary
A user equipment (UE) may receive, during release from a radio access network (RAN), resource information associated with attaching to the RAN, wherein the resource information is received based on the device being authenticated. The UE may store the resource information in a data structure associated with the UE, and may receive, when the UE includes a payload of data packets to transmit to the RAN, a signal from the RAN. The UE may determine, based on the signal, whether the RAN is a same RAN that provided the resource information, and may determine whether a strength of the signal from the RAN satisfies a threshold when the RAN is the same RAN that provided the resource information. The UE may attach to the RAN when the strength of the signal satisfies the threshold, and may provide the payload to the RAN via a random access channel of the RAN.
