Systems and methods for dynamic allocation of spectrum among cross-interfering radio nodes of wireless communications systems are disclosed. Multiple radio nodes may be deployed within a geographical region, and each radio node may support wireless communication over spectrum in which access is arbitrated by an external service not under the control of the operator of the radio node. Each radio node is configured to detect radio conditions which may indicate coexistence between the radio node and a neighboring radio node. A network entity associated with the radio node obtains radio condition information and determines a coexistence status between the radio node and the neighboring radio node, such as whether coexistence with the neighboring radio node is tolerable or intolerable. The network entity reports an indication of the coexistence status to a spectrum server, and the spectrum server reallocates the spectrum among the radio nodes.

A distributed radio access network (RAN) is provided. A selected wireless transceiver node(s) in a selected coverage cell receives a radio frequency (RF) test signal(s). The selected wireless transceiver node(s) determines an effective gain value based on a predefined characteristic of the RF test signal(s). The selected wireless transceiver node(s) communicates the effective gain value and other related parameters to a server apparatus in the distributed RAN. The server apparatus determines a common gain value for the selected wireless transceiver node(s) in the selected coverage cell based on the parameters. Accordingly, the selected wireless transceiver node(s) operates based on the common gain value. By determining a respective common gain value for each of the coverage cells in the distributed RAN, it may be possible for all the wireless transceiver nodes in the distributed RAN to communicate an uplink digital communications signal(s) without causing distortion in the uplink digital communications signal(s).

Distributed radio access networks (RANs) supporting coordinated amplifier gain optimization

Present systems and methods provide ways to provide access services to connecting wireless devices particularly for (but not limited to) neutral host networks. Steps include executing authentication between a connecting wireless device and a service provider, receiving an address of a remote gateway from the service provider, and providing access service for the wireless device including forwarding data received from the wireless device to the indicated remote gateway address in forwarding wireless device associated data received from the remote gateway address to the wireless device. Other ways are also disclosed.

Fifth generation (5G) non-standalone (NSA) radio access system employing virtual fourth generation (4G) master connection to enable dual system data connectivity. The 5G NSA radio access system employs a virtual 4G radio access node (RAN) to provide a logical master data connection to a user mobile communications device, and a 5G RAN to provide an additional, secondary high-speed data plane between the user mobile communications device to a core network. The virtual 4G RAN does not provide an actual 4G radio connection over-the-air to the user mobile communications device. Instead, the signaling transported between the user mobile communications device and the virtual 4G RAN is provided over a non-radio connection, such as an internet protocol (IP) connection. In this manner, the deployment of the 5G NSA radio access system employing the virtual 4G RAN can be achieved without updating existing 4G RANs and/or without deploying a new 4G RAN infrastructure.

Automatic cell discovery of a source radio access network (RAN) cell by a neighboring, target RAN by initiating a fake handover of a user equipment (UE) from a source RAN cell to a target RAN. A source RAN cell initiates a handover request using handover signaling to the target RAN(s). The handover request is a fake handover request without actual intention of handing over UE to the target RAN. The source RAN cell includes information in initiated handover request that can be used by target RAN to discover source RAN cell. The handover request will fail, because the handover request is not for any actual UE moving from the source RAN cell to the target RAN. However, the target RAN becomes aware of the source RAN cell as a result of this process and can add the source RAN cell (e.g., its EARFCN) to a list of its neighboring cells.

Discovery of a neighbor radio access system by a user mobile communications device serviced in a radio access network (RAN) for reporting to a serving system in the RAN. User mobile communications device serviced by a RAN is configured to scan one or more frequency ranges (e.g., bands) to discover other neighbor radio access systems. This is opposed to, for example, the user mobile communications device only searching for transmitted communications signals at specific center frequency (e.g., an EARFCN). There may be other radio access systems that operate neighbor cells and in other frequency bands in proximity the RAN serving the user mobile communications device. Discovered neighboring radio access systems can be reported by the user mobile communications device to its serving RAN in a measurement report, which can then be used by the serving RAN for other functionalities, such as trigger handovers of user mobile communications device for example.

In particular, systems and methods according to present principles configure physical eNodeB to have multiple virtual eNodeBs, where each virtual eNodeBs corresponds to a particular PLMN. Thus, each PLMN has its own virtual eNodeB which is hosted on a common shared physical eNodeB.

Described herein are techniques for identifying an access network in a wireless communication system. For example, the technique may involve determining a scheme for access network identification based on a public land mobile network-identifier (PLMN-ID) and an additional identifier. The technique may involve, receiving from the access network, broadcast information comprising the PLMN-ID and the additional identifier. The technique may involve determining that the access network belongs to a class of access networks that utilizes the additional identifier. The technique may involve identifying the access network using a combination of the PLMN-ID and additional identifier based on the class of access networks and the determined scheme.
