Temporary Mobile Terminal Authorization in Closed Group Radio Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standardized radio link allocation mechanisms fail to allow unauthorized mobile radio terminals to access a mobile radio network when there is no connection between the terminal and the network, preventing access even for temporary or manual authorization in areas without macro cell coverage.
Innovation Solution
A method that enables temporary and manual authorization of an unauthorized mobile radio terminal to access a base station by storing access authorization within an authorized terminal, allowing it to log in once within range, and requesting authorization through an authorization message from the base station, facilitated by the owner or administrator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standardized radio link allocation mechanisms are used to prevent uncontrolled access to closed group base stations, then network security is improved, but access availability for authorized users in areas without macro cell coverage deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-storing base station identifiers and access authorization data in the mobile terminal before the terminal needs to access the network. When macro cell coverage is unavailable, the terminal can immediately attempt to connect to pre-configured closed group base stations without requiring real-time authorization verification, thus resolving the contradiction between security and access availability.
2Reliability
If manual authorization procedures are implemented for unauthorized terminals to access closed group base stations, then access control security is improved, but system complexity and user effort increase
Solution Approach 1:
The patent applies self-service by enabling mobile terminals to automatically perform authorization procedures with closed group base stations using pre-stored credentials. The terminal independently manages the authorization process without requiring manual intervention from network operators or complex centralized authorization systems, thereby maintaining security while reducing system complexity.
3Speed
If pre-stored base station identifiers are kept in mobile terminals for direct connection attempts, then access speed is improved, but risk of unauthorized access increases
Solution Approach 1:
The patent implements local quality by differentiating the authorization requirements for different base station types. Closed group base stations use pre-stored identifiers with automatic authorization, while other base stations follow standard procedures. This localized approach enables fast connection establishment for authorized terminals while maintaining appropriate security controls, resolving the contradiction between speed and unauthorized access risk.

AI summary
The invention relates to a method for establishing a radio link between a non-authorised mobile radio terminal (B) and a base station (C) of a mobile radio network (D). According to the invention, an authorisation is given to the mobile radio terminal (B) in order to use the base station (C) as access to the mobile radio network (D), said mobile radio terminal (B) can be authorised at least temporarily, in particular manually, and the base station (C) transmits a corresponding release notice to the mobile radio terminal (B), and a radio link between the mobile radio terminal (B) and the base station (C) of the mobile radio network (D) is established.
