Wireless Device Registration Workflow for Congestion-Resilient Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, communication failures between network functions due to congestion can lead to transit losses, accumulation of stale information, and inefficient network utilization, resulting in failed access requests and suboptimal Key Performance Indicators (KPIs.
Innovation Solution
A session manager in the wireless network determines a workflow configuration for device registration, selecting a traffic routing function before requesting an access session from a policy enforcement function, thereby consolidating requests to enhance the efficiency of network access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network functions exchange information via dedicated pathways according to service-based architecture, then network access can be established through coordinated actions, but communication failures may occur due to congestion causing packet loss and transit losses
Solution Approach 1:
The patent applies preliminary action by having the session manager proactively determine workflow configuration and select traffic routing functions before actual access requests are processed. This advance preparation ensures that routing paths are pre-established, reducing the likelihood of communication failures during peak congestion periods when access requests need to be processed urgently.
2Reliability
If session manager waits for policy enforcement function before routing traffic, then proper access control can be enforced, but network access efficiency decreases due to sequential processing
Solution Approach 1:
The session manager performs preliminary actions by determining workflow configuration and selecting traffic routing functions in advance, before the policy enforcement function completes its processing. This allows the system to prepare routing paths proactively, so when policy enforcement is complete, traffic can be routed immediately without additional delays.
Solution Approach 2:
The patent implements dynamics by making the session manager's workflow determination adaptive based on real-time network conditions and device parameters. The workflow configuration can dynamically adjust which traffic routing function is selected, allowing the system to optimize for either reliability or efficiency depending on current network state, thus resolving the contradiction between sequential processing requirements and access efficiency.
3Reliability
If multiple coordination steps are taken for device registration, then comprehensive network control is achieved, but accumulation of stale information occurs and network utilization becomes inefficient
Solution Approach 1:
The patent applies the extraction principle by removing unnecessary coordination steps from the device registration process. The session manager independently determines workflow configuration and selects traffic routing functions without requiring intermediate coordination with the policy enforcement function. This extracts and eliminates redundant information exchange steps that previously caused stale information to accumulate in the system.
4Reliability
If traditional sequential processing is used for access sessions, then proper protocol compliance is maintained, but call set-up time increases and network KPIs degrade
Solution Approach 1:
The session manager performs preliminary determination of workflow configuration and traffic routing function selection before the formal access session establishment process begins. This preliminary action allows the system to prepare all necessary routing information in advance, so when the protocol-compliant session establishment proceeds, it can do so with pre-prepared information, significantly reducing call set-up time without compromising protocol compliance.
Data Source
AI summary
Technology is disclosed herein for registering a user device for access to a wireless network. In an implementation, a session manager of a wireless network receives a registration request for access to the network from a user device. The session manager determines a workflow configuration for the access based on parameters relating to the registration request. Prior to sending a request for an access session to a policy enforcement function, the session manager selects a traffic routing function of the wireless network for device access to the network and requests a traffic management session from the traffic routing function. The session manager sends a request for an access session to the policy enforcement function which includes traffic routing information. The session manager sends the user device information by which the user device can access the wireless network.
