Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cellular mobile systems lack an efficient method for handling message access in overloaded cells, leading to complex and inefficient management of message transmission and reception.
Innovation Solution
A system and method for cell identification (ID) barring using a short message service function (SMSF) that employs data structures to manage whitelisting and blacklisting of users, verifies PLMN and cell IDs, and utilizes dynamic counters for selective message barring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional random access channel (RACH) methods are used for message access in overloaded cells, then users can send and receive messages, but the system becomes complex and inefficient in handling message management
Solution Approach 1:
The patent segments the message management system into distinct functional components: a barring management function that maintains separate whitelist and blacklist data structures, and an access control function that evaluates messages against these lists. This segmentation allows independent optimization of each component, improving overall message handling efficiency while keeping system complexity manageable through modular design.
Solution Approach 2:
The patent implements preliminary action by pre-establishing whitelist and blacklist data structures containing user identifiers and cell IDs before message access attempts. The barring management function proactively configures access control rules and maintains these data structures in advance, enabling rapid message evaluation and decision-making without complex real-time computations during peak load conditions.
2Reliability
If access control is implemented to prevent UEs from accessing overloaded cells, then network overload is reduced, but the system complexity increases due to multiple barring features
Solution Approach 1:
The patent merges multiple access control mechanisms into a unified barring management function that handles both user-specific whitelisting/blacklisting and cell-based access control through a single evaluation process. This consolidation reduces system complexity by eliminating redundant control logic while maintaining comprehensive network overload management capabilities through integrated data structures that track both user identities and cell identifiers.
Solution Approach 2:
The patent creates a universal message evaluation mechanism that serves multiple functions: it controls access for overloaded cells, enforces user-specific barring rules, and manages both whitelist and blacklist operations through a single process. This multi-functional approach reduces the need for separate control systems while achieving comprehensive network management and overload protection.
3Ease of operation
If cell ID barring is implemented to restrict messages in specific cells, then localized network control is improved, but the complexity of managing multiple cell IDs and PLMN verification increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring the blacklist data structure with cell IDs and their associated PLMN identifiers before access control decisions are needed. The barring management function maintains these mappings in advance, allowing the message evaluation function to quickly verify cell ID restrictions and PLMN compatibility without performing complex real-time lookups, thereby simplifying localized message control while managing the complexity of multiple cell identifiers.
Data Source
AI summary
The present disclosure provides a system and a method for managing messages in a network. The system generates cell-identification (ID) barring in networks for restricting users (102) from sending and receiving messages in the network. Further, the system provides an efficient way to handle a logical barring of the devices from sending and receiving the messages. The system facilitates the barring of selective users in a defined cell-ID of a public land mobile network (PLMN), and therefore, provides flexibility while managing messages in the network. The system verifies if a mobile originating/mobile terminating (MO/MT) message is barred in the defined cell-ID in the PLMN and processes the MO/MT message based on the verification.
