LCS System Identity Disclosure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current location service (LCS) systems in mobile communications networks lack flexibility in managing user privacy, as they often reveal real identities of target users, which can be a security and privacy concern.
Innovation Solution
The LCS system determines whether to conceal the real identity of a target user by sending either a pseudonym or the real identity to a requestor, based on user indications or system assignments, allowing users to control their identity disclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the LCS system provides the real identity of the target user to the requestor, then the requestor can accurately identify and process the location information, but the user's privacy and security are compromised
Solution Approach 1:
The patent introduces a pseudonym as an intermediary element between the user's real identity and the requestor. The LCS system replaces the real identity with a pseudonym when providing location information, unless the user explicitly consents to identity disclosure. This mediator protects user privacy while still enabling accurate location-based services.
Solution Approach 2:
The patent implements dynamic identity disclosure control where the system can adaptively provide either a pseudonym or the real identity based on user preferences and service requirements. The identity disclosure mechanism is flexible and can change based on the specific service context and user authorization.
2Object-affected harmful factors
If the LCS system always conceals the real identity with a pseudonym, then user privacy is protected, but the requestor cannot accurately identify the user for service processing
Solution Approach 1:
The system dynamically adjusts the level of identity disclosure based on user preferences and service requirements. The LCS system can provide pseudonyms by default for privacy protection, but can switch to providing real identities when the user explicitly consents or when the service requires accurate identification.
Solution Approach 2:
The patent implements a feedback mechanism where user preferences regarding identity disclosure are captured and used to control subsequent identity provision. The system asks users for their preferences and uses this feedback to determine whether to provide pseudonyms or real identities in location services.
3Adaptability or versatility
If the LCS system implements flexible identity disclosure control, then user privacy and service flexibility are improved, but the system complexity increases
Solution Approach 1:
By using pseudonyms as an intermediary layer, the system achieves flexible identity disclosure without requiring complex authentication and authorization mechanisms for every service interaction. The pseudonym simplifies the complexity by providing a straightforward replacement mechanism that can be applied consistently across different services.

AI summary
The present invention discloses a method for processing requests for location, which comprises: A target UE sending a request for location to the Location Service (LCS) system and asking the LCS system to provide a requestor with the location information of the target UE; the LCS system positioning the target UE, acquiring the location estimate of the target UE, and deciding whether it is needed to hide the real identity of the target UE, and if yes, the LCS system sending the pseudonym and location information of the target UE to the requestor; otherwise, the LCS system sending the real identity and location information of the target UE to the requestor. The invention makes it possible for the LCS system to decide whether to hide the real identity of the target UE according to the user's requirement, improving the flexibility of the location service. As the LCS system is able to hide the real identity of the target UE, the security of using the location service is enhanced.
