Roaming Class Default Restrictions for Network Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile network systems lack flexibility in managing roaming connections, as they often rely on specific, granular roaming restrictions that can be cumbersome to specify and apply, leading to inefficiencies and increased resource consumption.
Innovation Solution
Implementing a system that supports default roaming restrictions on a per-roaming class of service basis, allowing network operators to define fallback behaviors for roaming classes of service when more specific restrictions are not specified, using a roaming determination engine to identify and apply default roaming restriction attributes based on roaming class identifiers, reducing the need for detailed MCC-MNC combinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If specific granular roaming restrictions are specified for each MCC-MNC combination, then roaming control precision is improved, but device complexity and resource consumption increase
Solution Approach 1:
The patent segments roaming restrictions into two levels: default restrictions applicable to all roaming classes of service, and specific restrictions applicable to particular MCC-MNC combinations. This hierarchical segmentation allows the system to maintain high control precision for specific cases while avoiding the complexity of defining every possible combination individually.
Solution Approach 2:
Instead of requiring complete specification of restrictions for every MCC-MNC combination, the patent applies partial action by using default restrictions as a baseline and only requiring specific restrictions where needed. This reduces the overall complexity while maintaining adequate control precision for critical roaming scenarios.
2Ease of operation
If default roaming restrictions are implemented per roaming class of service, then ease of operation is improved, but roaming control flexibility may be reduced
Solution Approach 1:
The patent applies local quality by allowing different default roaming restriction attributes to be defined for different roaming classes of service (e.g., different defaults for roaming COS A versus roaming COS B). This enables tailored default behaviors for different user categories while maintaining the simplicity of default-based management.
Solution Approach 2:
The system dynamically selects which roaming restrictions to apply based on the identified roaming class of service. The roaming determination engine adapts the restriction set according to the subscriber's roaming COS, balancing ease of operation with the flexibility to provide different levels of control for different service classes.
3Reliability
If comprehensive roaming restriction databases are maintained, then roaming control reliability is improved, but use of energy and processing resources increase
Solution Approach 1:
The patent implements preliminary action by pre-defining default roaming restriction attributes for each roaming class of service. When a subscriber roams, the system can immediately apply the appropriate default restrictions based on the identified roaming COS without needing to query comprehensive databases for every possible scenario, thereby reducing processing resources while maintaining reliability.
Data Source
AI summary
In some examples, a computer-readable medium includes instructions. The instructions may be executable by a processing resource to maintain a default roaming restrictions database that stores default roaming restriction attributes specific to roaming classes of service defined by a network operator. The default roaming restriction attributes may be specific to the roaming classes of service independent of mobile country code and mobile network code. The instructions may also be executable by the processing resource to perform a lookup into the default roaming restrictions database to identify a particular default roaming restriction attribute specific to a particular roaming class of service defined by the network operator.
