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.

Abstract: In one example embodiment, a server obtains a first indication of a first identifier associated with a user equipment in a wireless network, and first telemetry data associated with the first indication. The server obtains, from a network entity including a base station entity serving wireless communication in the wireless network, a second indication of the first identifier and second telemetry data associated with the second indication. The server determines that the first indication and the second indication match. In response to determining that the first indication and the second indication match, the server correlates the first telemetry data and the second telemetry data.

Abstract: A radio access network (RAN) of a neutral host network (NHN) provides communications in a plurality of small cells, and is a shared resource with shared access by a plurality of mobile network operators (MNOs) via a multi-operator core network (MOCN). A base station maintains a neighbor list of small cell frequencies of neighboring small cells of a small cell, and broadcasts, to a user equipment (UE), a system information message which includes the neighbor list. The base station additionally maintains a plurality of operator-specific neighbor lists of one or more macro-cell frequencies of one or more neighboring macro-cells, where each such list is associated with a respective one of a plurality of macro-cellular networks of the MNOs. The base station transmits, to the UE, a message including a selected one of the operator-specific neighbor lists associated with an identified one of the mobile network operators of the UE.
