Mobile Device Domain-Specific Communication Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The availability of multiple communication domains on a single mobile device poses security challenges, as enterprise domains are generally more secure than non-enterprise domains, and administrators need to restrict certain call features to maintain control over the use of these domains.
Innovation Solution
A mobile device with a processor and memory that includes a domain module to determine the request domain of a communication service request and a communication restriction module to apply applicable restrictions, ensuring that communication service requests adhere to set restrictions based on the domain, thereby managing and controlling communications across different domains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication domains are made available on a single mobile device, then communication versatility and user convenience are improved, but security control and administrative management deteriorate
Solution Approach 1:
The patent segments communication domains into distinct categories (enterprise domain and non-enterprise domain) with separate security policies and restrictions. Each domain is independently managed through domain-specific restriction sets, allowing the system to maintain multiple communication channels while enforcing appropriate security controls for each segment.
Solution Approach 2:
The patent introduces an intermediary mechanism (communication manager/module) that sits between the user and the communication domains. This intermediary evaluates communication requests, determines the appropriate domain, applies relevant restrictions, and enforces security policies, thereby maintaining both versatility and security control.
2Reliability
If administrators restrict certain call features on a mobile device, then security control over enterprise service is improved, but ease of operation and user flexibility deteriorate
Solution Approach 1:
The patent applies local quality by implementing domain-specific restriction sets that target only particular communication domains or specific features within domains. Rather than applying blanket restrictions across all communication functions, the system selectively applies restrictions only where security concerns exist, preserving user flexibility in unaffected areas.
Solution Approach 2:
The patent implements dynamic restriction application where the system adapts restrictions based on the communication domain, request type, and contextual factors. Restrictions are not static but are dynamically evaluated and applied only when relevant to the current communication request, maintaining user flexibility for approved operations while enforcing security controls when needed.

AI summary
A mobile device and a method for providing security to a mobile device having two or more communication domains is provided. The mobile device receives a communication service request. The communication domain of the communication service request is determined, the request domain being one of the two or more communication domains of the mobile device. A set of applicable restrictions is then determined from a list of communication restrictions comprising restrictions on use of services of the mobile device for each of the two or more communications domains. These applicable restrictions are then applied to the communication service request by the mobile device.
