IMS Network Entity Tagging for Non-Single-Registration Service Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-Single-Registration (SR) devices face challenges in IMS networks when implementing Implicit Registration Sets (IRS), leading to increased network load and ambiguity in assigning telecommunication services to the correct public identity, preventing network operators from adopting option B, which reduces signaling traffic.
Innovation Solution
Introducing an additional individual tag that links telecommunication services to specific public identities within an Implicit Registration Set, allowing the network entity to differentiate between SR and non-SR devices and accurately assign services, enabling backwards compatibility and reducing network load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If Option B (Implicit Registration Set) is implemented to reduce network load, then network signaling traffic is reduced, but non-SR devices experience service assignment ambiguity and cannot be properly differentiated
Solution Approach 1:
The patent segments the Implicit Registration Set by introducing individual tags that divide the set into device-specific subsets. Each non-SR device receives a unique tag that identifies which public identities within the IRS are assigned to that specific device, enabling precise service routing while maintaining the reduced registration overhead of Option B.
Solution Approach 2:
The network entity acts as an intermediary that manages the mapping between public identities and non-SR devices using individual tags. This mediator resolves the ambiguity by maintaining and querying the association data, allowing the network to correctly route services to specific non-SR devices without requiring them to perform complex registration procedures.
2Productivity
If multiple public identities are assigned to one Implicit Registration Set, then registration frequency is reduced, but the network cannot determine which device should receive which service
Solution Approach 1:
The patent applies local quality by assigning unique individual tags to specific non-SR devices within the IRS framework. Each tag carries device-specific information that enables the network entity to locally determine which device should receive which service, rather than requiring global device identification through multiple registrations.
Solution Approach 2:
The network entity performs preliminary action by pre-establishing the mapping between individual tags and public identities during the service assignment phase. This pre-computed mapping information is stored and readily available when services need to be routed, eliminating the need for runtime device discovery or multiple registration attempts.
3Loss of energy
If Option B is implemented without differentiation mechanisms, then network load is reduced, but backwards compatibility with non-SR devices is lost
Solution Approach 1:
The individual tag mechanism provides universality by enabling the network to handle both SR and non-SR devices through a common framework. The same IRS structure and tag-based differentiation can accommodate multiple device types and capability levels, allowing the network to maintain Option B benefits while supporting diverse device configurations.
Solution Approach 2:
The system introduces dynamics by allowing flexible assignment of individual tags to different non-SR devices based on their specific requirements and capabilities. The network entity can dynamically create, modify, and revoke tag assignments as devices are added, removed, or upgraded, maintaining adaptability while preserving the reduced registration overhead.
