Limited Network Access for Unsubscribed Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users without a subscription to a network service plan are unable to access network services, limiting their ability to perform tasks such as emergency calls or accessing specific applications, as existing systems block unauthorized access.
Innovation Solution
Implementing a system that allows user devices to access a limited set of services without a subscription by sending a connection request to a base station, which provides a list of available limited services, and using a mobility management entity to establish data flows and service parameters, enabling access to services like emergency calls or web pages, with costs potentially covered by third parties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network devices block access of user devices without subscription, then network service security is improved, but user accessibility to essential services deteriorates
Solution Approach 1:
The network service is segmented into multiple access levels: full subscription-based access and limited unauthorized access. The system divides services into categories (full access, limited access, blocked) and applies different authorization rules to each segment, allowing unsubscribed users to access essential services like emergency calls while maintaining security for premium services.
Solution Approach 2:
Different quality levels of access are provided to different user groups. Subscribed users receive full-quality access to all services, while unsubscribed users receive limited-quality access to essential services only. The network device applies local quality control by evaluating each service request against the user's subscription status and granting appropriate access levels.
2Quantity of substance
If network devices require subscription for service access, then network revenue is improved, but user flexibility for occasional usage deteriorates
Solution Approach 1:
The system dynamically adjusts access rights based on real-time subscription status. Users can transition between subscribed and unsubscribed states, and the network device dynamically modifies their access privileges accordingly. This dynamic approach allows users to have full flexibility when needed (unsubscribed with limited access) and full access when they commit to the service (subscribed).
Solution Approach 2:
Instead of requiring full subscription for all services, the system provides partial action by granting limited access to essential services for unsubscribed users. This partial access is sufficient for occasional needs like emergency calls or customer service, eliminating the need for full subscription and allowing users to pay only when they need comprehensive service.
3Ease of operation
If network devices provide full service access to unsubscribed users, then user convenience is improved, but network resource consumption increases
Solution Approach 1:
Network resources are segmented and allocated based on service type and user subscription status. Essential services for unsubscribed users (emergency calls, customer service) consume limited resources, while premium services remain reserved for subscribed users. This segmentation prevents excessive resource consumption by unsubscribed users while maintaining convenience for essential needs.
Solution Approach 2:
The system changes access parameters (bandwidth allocation, service quality, resource limits) based on subscription status. Unsubscribed users experience parameter-constrained access to essential services, ensuring network resources are preserved for subscribed users. The network device dynamically adjusts these parameters to balance user convenience with resource conservation.
Data Source
AI summary
A network device is configured to receive, from a user device that is not subscribed to a network associated with the network device, a connection request identifying a particular service, of one or more services, to provide to the user device. The system may further identify a packet data network (PDN) to establish based on the particular service; identify one or more parameters, associated with the PDN and identifying a data flow, associated with the particular service, that can be provided to the user device; and establish the PDN based on the one or more PDN parameters. The PDN may permit only the data flow, associated with the particular service, to be transmitted to the user device. The system may further provide the data flow, associated with the particular service, to the user device via the PDN.
