Wireless UE Encoded URI for Priority Service Identity Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless Priority Service (WPS) in visited wireless communication networks exposes user identity information and may be blocked due to unsupported networks, leading to delayed SIP signaling during emergencies and network congestion.
Innovation Solution
The wireless User Equipment (UE) correlates network Identifiers with instructions to use encoded public Uniform Resource Identifiers, allowing for anonymous or secure tunneling to maintain user anonymity and ensure priority communication services, even in unsupported networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If WPS is used in visited wireless communication networks, then priority voice calling service is provided, but user identity information is exposed
Solution Approach 1:
The patent introduces an encoded public URI as an intermediary that masks the user's real identity information. Instead of directly exposing the user's public SIP URI or TEL URI in the visited network, the system uses an encoded version that acts as a mediator, allowing priority service delivery while protecting user identity from exposure to the visited network's IMS.
2Reliability
If WPS is used in visited wireless communication networks, then priority communication service is enabled, but the network may block calls due to lack of support
Solution Approach 1:
The encoded public URI serves as an intermediary mechanism that allows WPS-capable devices to operate in visited networks regardless of whether those networks natively support WPS. The encoding scheme enables the priority service request to be transmitted in a format that can be processed even by networks that don't recognize traditional WPS indicators.
Solution Approach 2:
The patent transforms the user identifier from its traditional form (public SIP URI or TEL URI) into an encoded version. This parameter change in the identifier format allows the priority service request to be conveyed in a way that is compatible with networks that may not support traditional WPS implementations.
3Reliability
If traditional WPS implementation is used, then priority service is provided, but SIP signaling may be delayed during network congestion
Solution Approach 1:
The encoded public URI acts as a mediator that enables priority SIP signaling to be recognized and handled with appropriate QoS treatment. By embedding priority indicators within the encoded identifier structure, the system ensures that SIP signaling messages receive priority processing even during network congestion, preventing delays in call setup.

AI summary
A wireless User Equipment (UE) delivers a priority communication service. In the UE, circuitry correlates a network Identifier (ID) for a wireless communication network with an instruction for the priority communication service. The circuitry identifies a user request for the priority communication service when the wireless UE is wirelessly attached to the wireless communication network. In response, the circuitry responsively identifies the instruction based on the correlation with the network ID. The circuitry exchanges network signaling with a radio based on the instruction and exchanges user data with the radio responsive to the exchange of the network signaling. The radio exchanges the network signaling and the user data with the UE circuitry and wirelessly exchanges the network signaling and the user data with the wireless communication network. The instruction may direct the circuitry to use an encoded public Uniform Resource Identifier (URI) to identify the UE to the wireless communication network.
