Abstract: A base station operative in a Citizens Broadband Radio Service (CBRS) band controlled according to a shared access system (SAS) may be configured for automated neighbor frequency provisioning. The base station may maintain an active neighbor list of small cell frequencies of active neighboring small cells, which is created or updated by performing a scanning operation and adding small cell frequencies of scanned neighboring small cells to the active neighbor list. The base station may receive, from an active neighboring base station having a connection established therewith, one or more messages including a neighbor list of small cell frequencies of neighboring small cells that neighbor the active neighboring small cell. At least some of the neighboring small cells of the active neighboring small cell may be added to the active neighbor list of the base station based on signal strength of user equipment (UE) measurements.

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.

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) entity (e.g. an eNodeB) may be configured to facilitate multicast communication in a local private Third Generation Partnership Project (3GPP) network. The RAN entity may receive a user data packet tunneled in an IP message via one of a plurality of downlink tunnels. The RAN entity may select, from a plurality of stored mappings, one of a plurality of multicast group identifiers that is mapped to an identified one of a plurality of downlink tunnel endpoint identifiers that matches a downlink tunnel endpoint identifier from a tunnel header of the IP message, as well as one of a plurality of sets of UE identifiers that is mapped to the selected multicast group identifier. The RAN may send, for each one of the UE identifiers in the selected set of UE identifiers, the user data packet for transmission to a UE associated with the UE identifier.

Abstract: In one example, a user equipment (UE) has a non-Third Generation Partnership Project (non-3GPP) radio transceiver for communication in a local private non-3GPP wireless network and a 3GPP radio transceiver for communication in a 3GPP network, where the 3GPP network may be a public 3GPP network or a local private 3GPP network operative in a shared spectrum according to a system for shared spectrum access. Initially, the UE may operate the 3GPP radio transceiver for communication in the public 3GPP network, without performing regular scanning for the local private 3GPP network. In a scan operation using the non-3GPP radio transceiver, the UE may receive from a non-3GPP access point of the local private non-3GPP wireless network one or more messages including one or more information elements. If an information element indicates presence of the local private 3GPP network, the UE may identify and register with the local private 3GPP network.
