OPTIMIZED DEREGISTRATION OF USER EQUIPMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 17962913 titled 'OPTIMIZED DEREGISTRATION OF USER EQUIPMENT

Simplified Explanation

The systems and method disclosed herein optimize the deregistration of user equipment (UE) from the GC. For example, when the UE operates in single-registration mode, for AMF 3GPP access registration with drFlag attribute set to false (or to be absent) in UDM/UDR, a “new attribute”, singleRegIndication, is defined. The AMF sets the singleRegIndication value to “NO_INDICATION” when there is no N26 interface connection to MME. UDM will not instruct HSS to cancel MME (and SGSN/VLR) if there is an old AMF 3GPP registration for which “NO_INDICATION” or “DEREGISTER_SN” is set as the singleRegIndication value (i.e. the old AMF was already registered with the single registration). Otherwise, the AMF sets the singleRegIndication value to “DEREGISTER_SN” when the AMF has established a N26 interface connection to the old MME. UDM can instruct HSS to cancel the MME (and SGSN/VLR).

• Optimization of deregistration process for user equipment (UE) from the GC
• Introduction of a new attribute, singleRegIndication, for AMF 3GPP access registration
• Differentiation of deregistration indications based on N26 interface connection status
• Instruction to cancel MME (and SGSN/VLR) based on single registration status

Potential Applications

The technology can be applied in telecommunications networks to streamline the deregistration process of user equipment, improving network efficiency and resource management.

Problems Solved

1. Efficient deregistration of user equipment from the GC 2. Clear differentiation of deregistration indications based on network connection status

Benefits

1. Improved network performance 2. Enhanced resource utilization 3. Simplified management of user equipment registrations

Potential Commercial Applications

The technology can be utilized by telecommunication companies to enhance the operational efficiency of their networks, leading to cost savings and improved customer experience.

Possible Prior Art

There may be existing systems or methods in the telecommunications industry that address aspects of user equipment deregistration, but the specific optimization and differentiation of deregistration indications based on network connection status as described in this patent application may be novel.

How does this technology impact user privacy in telecommunications networks?

The technology described in the patent application focuses on optimizing the deregistration process of user equipment from the GC. However, it is essential to consider how this optimization may affect user privacy within telecommunications networks. For example, does the streamlined deregistration process introduce any potential vulnerabilities or risks to user data privacy?

What are the potential scalability challenges of implementing this technology in large-scale telecommunications networks?

While the optimization of deregistration processes can bring efficiency benefits, implementing such technology in large-scale telecommunications networks may pose scalability challenges. For instance, how does the system handle a high volume of deregistration requests simultaneously? Are there any limitations or bottlenecks that could arise when scaling this technology to larger network infrastructures?
