Use of a communication profile by a plurality of mobile terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to ensure that only one mobile terminal can use a communication profile at a time, leading to synchronization disruptions when terminals move out of network range or lose connectivity.
Innovation Solution
A method and system for mobile terminals that utilize identifiers to coordinate the activation and deactivation of communication profiles, ensuring that only the appropriate terminal with the correct identifier can activate the profile, using a notification and deactivation request mechanism to prevent erroneous deactivation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal activates a communication profile and notifies an external entity, then the terminal can use the communication profile, but if the terminal goes outside network range, synchronization is disrupted and multiple terminals may have the profile activated
Solution Approach 1:
The patent applies preliminary action by having the terminal generate and store an identifier for the activated communication profile before any deactivation request occurs. This pre-stored identifier enables the terminal to later verify whether a received deactivation request is legitimate by comparing it with the pre-stored identifier, thus preventing erroneous deactivation due to synchronization disruptions.
Solution Approach 2:
The patent implements feedback by requiring that deactivation requests include an identifier that matches the identifier stored by the activating terminal. The external entity provides feedback about the activation state, and the terminal uses this feedback along with identifier verification to determine whether to deactivate the profile, ensuring synchronized state management across distributed terminals.
2Productivity
If deactivation requests are transmitted without identifier verification, then deactivation can be performed quickly, but erroneous deactivation may occur when deactivation requests are delayed or overtaken
Solution Approach 1:
The terminal generates and stores the identifier for the activated communication profile in advance, before any deactivation request is received. This preliminary action ensures that when a deactivation request arrives, the terminal can immediately verify the request's legitimacy by comparing the included identifier with the pre-stored one, enabling both quick and accurate deactivation decisions without delay.
3Quantity of substance
If an identifier is determined by the terminal and transmitted with the notification, then fewer messages are exchanged, but the external entity cannot ensure consistency of identification
Solution Approach 1:
The external entity provides feedback by validating and forwarding the identifier generated by the terminal, or by generating its own identifier and transmitting it back to the terminal. This feedback loop ensures that both the terminal and external entity have consistent identification information, maintaining reliability while minimizing message exchange.
4Reliability
If the external entity transmits deactivation requests to all terminals with the same profile, then profile uniqueness is maintained, but unnecessary deactivation requests are sent to terminals that should not be deactivated
Solution Approach 1:
The external entity uses feedback in the form of identifier verification to determine which terminals should receive deactivation requests. By comparing identifiers, the external entity can selectively send deactivation requests only to the terminal that should actually deactivate the profile, avoiding unnecessary requests to other terminals while maintaining profile uniqueness.
Data Source
AI summary
A mobile terminal includes a communication device to communicate with an external entity, a storage device to store an identifier, and a processing device. The processing device activates a communication profile, transmits a notification relating to the activation to an external entity, and stores an identifier of the activation in the storage device. The processing device further receives a deactivation request and an identifier from the external entity and deactivates the communication profile if the received identifier corresponds to the stored identifier. The identifier can be determined by the mobile terminal and transmitted from the mobile terminal to the external entity. The identifier can also be determined by the external entity and transmitted to the mobile terminal.
