Managed Access System Device Identity Creation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Correctional facilities face challenges in identifying and controlling contraband mobile communications devices, which pose security risks and revenue losses due to their ability to circumvent monitored communication systems, and existing detection methods like jamming and mobile detection equipment have limitations.
Innovation Solution
A system and method for creating a unique device identity for mobile communications devices by combining equipment identification information and subscriber identification information, using International Mobile Station Equipment Identity (IMEI) and International Mobile Subscriber Identity (IMSI) or Mobile Equipment Identifier (MEID) and Mobile Identification Number (MIN), to facilitate faster analysis and monitoring of communications within controlled-environment facilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If traditional detection methods (jamming, mobile detection equipment) are used to detect contraband devices, then detection capability is provided, but the methods have limitations and are not sufficiently effective
Solution Approach 1:
The patent introduces a Managed Access System (MAS) as an intermediary between the facility's communication infrastructure and mobile devices. The MAS captures device identification information (IMEI, IMSI, MEID, MIN) from mobile devices attempting to communicate within the facility, creating a reliable detection mechanism that identifies contraband devices through their unique identifiers rather than relying on less reliable detection methods
2Measurement precision
If multiple identification parameters (IMEI, IMSI, MEID, MIN) are collected and analyzed, then device identification accuracy is improved, but system complexity increases
Solution Approach 1:
The patent merges multiple device identification parameters (IMEI, IMSI, MEID, MIN) into a unified device ID through a hashing function. This consolidation approach maintains high identification accuracy by incorporating all relevant parameters while reducing system complexity by representing the device with a single identifier for subsequent monitoring and analysis operations
3Ease of operation
If contraband devices are allowed to communicate freely, then inmate communication needs are met, but security risks and revenue losses occur due to circumvention of monitored systems
Solution Approach 1:
The patent implements a feedback mechanism where the Managed Access System continuously monitors mobile devices within the facility, captures their identification information, and provides real-time feedback about device status. This enables the system to distinguish between authorized and contraband devices, allowing legitimate communication needs to be met while detecting and preventing security risks through ongoing monitoring and feedback loops

AI summary
Systems and methods for creation of a device identity (ID) for mobile communications devices may capture equipment identification information and subscriber identification information for mobile communications devices and combine them to create a device identity for each pairing of equipment identification information and subscriber identification information captured. Such mobile communications devices, may be operating in association with a controlled-environment facility and the equipment identification information and subscriber identification information are captured by a controlled-environment facility mobile communications managed access system (central access point) and/or by a controlled-environment facility contraband mobile communications device assessment system (access point(s)). Thus, the device identity for each pairing of equipment identification information and subscriber identification information may be for mobile communication devices operating in association with the controlled-environment facility, including contraband communications devices operating within the facility.
