==METHOD OF CORE NETWORK APPARATUS, METHOD OF RADIO ACCESS NETWORK, CORE NETWORK APPARATUS AND RADIO ACCESS NETWORK - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240107481 titled 'METHOD OF CORE NETWORK APPARATUS, METHOD OF RADIO ACCESS NETWORK, CORE NETWORK APPARATUS AND RADIO ACCESS NETWORK

==Simplified Explanation==

The patent application describes techniques for registering a user equipment (UE) to a new Access and Mobility Management Function (AMF) when the new AMF determines that the old AMF is disjoint, meaning they are not connected. The new AMF fetches the UE context (5GMM and SGSM context) from the old AMF via the New Generation Radio Access Network (NG-RAN). The new AMF sends a request message to the old AMF to fetch the UE contexts, and the old AMF responds with the UE contexts. Based on these context transfers, the UE is registered to the new AMF.

* New AMF registers UE to a new AMF when the old AMF is disjoint.
* Context transfer occurs between old and new AMF via NG-RAN.
* UE context includes 5GMM and SGSM context.
* Request and response messages are exchanged between old and new AMF.

== Potential Applications ==
The technology described in this patent application could be applied in the telecommunications industry for seamless handover of user equipment between different Access and Mobility Management Functions.

== Problems Solved ==
1. Seamless registration of user equipment to a new AMF when the old AMF is disjoint.
2. Efficient transfer of UE context between AMFs via NG-RAN.

== Benefits ==
1. Improved user experience with uninterrupted connectivity.
2. Enhanced network management and optimization.
3. Streamlined handover process for user equipment.

== Potential Commercial Applications ==
Optimizing network performance and enhancing user experience in 5G networks.

== Possible Prior Art ==
There may be prior art related to context transfer and handover procedures in mobile networks, but specific examples are not provided in the patent application.

=== Unanswered Questions ===

== How does this technology impact network efficiency and resource utilization in 5G networks? ==
The patent application does not delve into the specific impact of this technology on network efficiency and resource utilization in 5G networks.

== What are the potential security implications of transferring UE contexts between AMFs? ==
The patent application does not address the potential security implications of transferring UE contexts between AMFs.


==Original Abstract Submitted==

disclosed are techniques for registering a user equipment (ue) to a new access and mobility management function (amf). when a new access and mobility management function (amf) determines that an old amf is disjoint amf i.e. they are not connected, then the new amf fetches the ue context (5gmm and sgsm context) from the old amf via new generation radio access network (ng-ran). the new amf routes a namf_communication_uecontexttransfer request message to the old amf to fetch the ue contexts via ng-ran. the old amf sends the ue contexts in the namf_communication_uecontexttransfer response message to the new amf via ng-ran. based on the context transfers between the new amf and the old amf, the ue is registered to the new amf.
