Smart GNB coordination in telecommunications networks

A telecommunications network comprising:

• at least one processor in communication with a first network node;
• and
• a memory storing instructions that, when executed by the at least one processor, cause the first network node to:
• receive a context release approval request from a second network node associated with an Access and Mobility Management Function (AMF), wherein the context release approval request is in response to a path switch request received by the second network node, the path switch request indicating a handover request for a user equipment (UE) from a first gNB to a second gNB, wherein the UE is associated with a radio access network (RAN) identifier corresponding to a communication session between the UE and the first gNB and an AMF identifier corresponding to a communication session between the UE and the AMF,
• determine whether the AMF identifier is associated with another RAN identifier, and
• in response to a determination that the AMF identifier is not associated with another RAN identifier, cause the second gNB to issue a UE context release request to the second network node, the UE context release request configured to cause the second network node to terminate all communication sessions associated with the AMF identifier.

A non-transitory computer-readable medium storing instructions that, when executed by at least one processor of a computer in a telecommunications network, cause the computer to perform operations comprising:

• receiving, at a first network node associated with an Access and Mobility Management Function (AMF), a path switch request, the path switch request indicating a handover request for a user equipment (UE) from a first gNB to a second gNB, wherein the UE is associated with a radio access network (RAN) identifier corresponding to a communication session between the UE and the first gNB and an AMF identifier corresponding to a communication session between the UE and the AMF;
• determining whether the AMF identifier is associated with another RAN identifier;
• and
• in response to a determination that the AMF identifier is not associated with another RAN identifier, causing the second gNB to issue a UE context release request to the first network node, the UE context release request configured to cause the first network node to terminate all communication sessions associated with the AMF identifier.
