Wireless Paging Identity Management for Privacy and Low Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in maintaining privacy and security of devices accessing various services, particularly in 5G and beyond, as service identifiers can reveal device information and lead to tracking, and devices must monitor multiple paging occasions for different services, consuming power.
Innovation Solution
Implementing a temporary service identifier (TSID) managed by an identity and routing service to replace service identifiers, and a centralized paging service to coordinate paging across multiple services, ensuring privacy and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If service identifiers are used to identify services, then service identification is straightforward, but device privacy is compromised and tracking becomes possible
Solution Approach 1:
The patent introduces a temporary service identifier (TSID) as an intermediary between the service and the device. The TSID is assigned to the service by the identity and routing service and used in paging messages instead of the permanent service identifier. This mediator allows service identification to function while preventing direct exposure of the service's true identity, thereby protecting device privacy and preventing tracking.
2Reliability
If devices monitor multiple paging occasions for different services, then all services can be paged reliably, but power consumption increases
Solution Approach 1:
The patent merges the paging functionality for multiple services into a single centralized paging service. Instead of devices monitoring separate paging occasions for each service, all services route paging requests through the centralized paging service, which consolidates paging into a single monitoring occasion. This combining approach maintains reliable service paging while significantly reducing device power consumption.
Solution Approach 2:
The centralized paging service performs multiple functions: it receives paging requests from various services, determines the target device, and transmits unified paging messages. This multi-functional approach allows a single paging infrastructure to handle paging for multiple services, eliminating the need for devices to monitor multiple service-specific paging occasions.
3Object-affected harmful factors
If temporary service identifiers are introduced, then device privacy is enhanced, but system complexity increases
Solution Approach 1:
The patent extracts the identity management functionality from the individual services and places it in a dedicated identity and routing service. This separate entity is responsible for generating and managing temporary service identifiers, thereby simplifying the overall system architecture by centralizing complexity in a specialized component rather than distributing it across multiple services.

AI summary
An apparatus, method and computer-readable media are disclosed for performing wireless communications. For example, a process for wireless communications can include transmitting, to an identity and routing service, a service registration request, wherein the service registration request includes a service identifier for the network service, wherein the network service is separate from the identity and routing service; receiving, from the identity and routing service, a first temporary service identifier (TSID) for the network service; allocating a first temporary device identifier (TUID) to a device; and transmitting the first TSID and first TUID to the device for a first security context.
