Patent ID: 11785509

Abstract:
A method is provided for avoiding context transfers by a first Access and Mobility Management Function (AMF) connected to a first gNB to a second AMF when a user equipment (UE) in idle mode moves from the first gNB to a second gNB. The method may include provisioning the first AMF and the second AMF with the same tracking area identity (TAI), the first AMF and the second AMF s being connected to a respective enterprise gNB. The method may also include configuring the 5G packet core network comprising a session management function (SMF) in communications with the first AMF and the second AMF, to avoid transferring a UE context from the first AMF to the second AMF when the user equipment (UE) in the idle mode moves from a first AMF to the second AMF. The UE context remains with the first AMF.
