A system and method for reducing power consumption and interference in a communications system that has multiple base radios. A base radio controller assigns priorities to the base radios in the system. When higher priority base radios have excess capacity, intracell handovers are used to consolidate communications from lower priority base radios to higher priority base radios. After transferring communications to higher priority base radios, the lower priority base radios can attenuate or shut off their transmitted signal in order to reduce or eliminate all the interference they cause other base stations in the system, and reduce transmission power requirements.

A method and system for private wireless network communications is provided. A private wireless network controller is coupled to a Private Branch Exchange (PBX), a private base transceiver station, and a Public Switched Telephone Network (PSTN). The private base transceiver station is coupled to a wireless macro network. The private wireless network controller and private base transceiver station allow connection of interconnect and dispatch wireless calls, which originate on the private wireless network, to other mobile stations on the private wireless network, to terminals connected to the PBX, to mobile stations on wireless macro networks, and to terminals coupled to the PSTN.

An LTE network extension (LNE) system includes an LTE access gateway (LAG) and a provisioned database. A plurality of LTE access radios in the LNE system broadcast the same shared PLMN ID (sPLMN ID). The sPLMN ID corresponds to a plurality of service provider core networks, each with a different PLMN. The provisioned database includes information identifying which networks are allowed to use the LNE system and includes service provider network address information. An LTE access radio, transmitting the sPLMN ID detects an attach request from a UE, and forwards the attach request to the LAG, which decides if access is to be allowed, based on a service provider home network PLMN included in an IMSI in the attach request and information in the provisioned database. If access is allowed, the LAG serves as a proxy between the LTE access radio and the UE's service provider home network.

In certain embodiments, one or more Citizens Broadband Radio Service (CBRS) service devices (CBSDs) may be migrated from their current Spectrum Access System (SAS) to a new SAS, where at least one existing PAL or GAA spectrum grant is transferred from the current SAS to the new SAS without waiting for a timer associated with the existing spectrum grant to expire. CBSDs may be migrated one at a time or multiple CBSDs of a single service provider may be migrated in a single process where the multiple CBSDs are identified by a shared organization ID associated with the service provider. In either case, a migrating CBSD can continue to use its previously existing spectrum grants after migrating to the new SAS without significant delay.

Disclosed herein are methods and systems for using out-of-band spectrum for shared spectrum registration and increased link reliability and capacity. A method for customer premise equipment (CPE) attachment and registration in a shared spectrum system includes attaching, by the CPE to a shared spectrum access point, using an out-of-band spectrum, where the out-of-band spectrum is out-of-band with respect to a shared spectrum of the shared spectrum system, registering, by the CPE with a spectrum access system, using the out-of-band spectrum upon successful attachment with the shared spectrum access point, and communicating, by the CPE, using at least the shared spectrum upon successful registration with the spectrum access system.

According to one configuration, a system includes provisioning hardware and a wireless station that supports communications with one or more communication devices. The wireless station receives a first notification from the provisioning system. The first notification indicating that the wireless station is assigned to a first allocation management resource. The first allocation management resource operable to allocate wireless resources for use by the wireless station to support wireless communications. The wireless station communicates with the first allocation management resource to receive allocation information indicating the wireless resources allocated for use by the wireless station. In response to receiving a second notification that the wireless station has been reassigned to a second allocation management resource, the wireless station communicates with the second allocation management resource instead of the first allocation management resource to receive the allocation information.

A network environment includes a first station, a second station, and a communication manager. The communication manager monitors a backhaul between the first station and the second station. In one arrangement, the first station is a wireless access point providing wireless connectivity to multiple mobile communication devices. During operation, the backhaul conveys communications between the first station and the second station. Based on the monitoring, the communication manager produces a metric indicating an ability of the backhaul to convey communications. Based on the metric, the communication manager determines a split of multiple processing layers in a wireless protocol stack. To accommodate the split, the communication manager assigns a first portion of multiple network communication layers to the first station for processing and a second portion of the multiple network communication layers to the second station for processing.
