Abstract
Aspects of the subject disclosure may include, for example, obtaining CBRS information from SAS equipment, where the CBRS information includes channel assignments associated with different coverage locations; and providing the channel assignments to one or more EMSs according to the CBRS information to enable CBRS devices to provide communication services including handoffs via the channel assignments to one or more end user devices in coverage areas of the one or more CBRS device. Other embodiments are disclosed.
Claims20
A device operating in a network core of a network operator, comprising:
- a processing system including a processor;
- and
- a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
- obtaining Citizens Band Radio Service (CBRS) information from Spectrum Access System (SAS) equipment, the CBRS information including channel assignments associated with different coverage locations;
- and
- providing the channel assignments to one or more Element Management Systems (EMSs) according to the CBRS information to enable the one or more EMSs to update CBRS devices for handoffs during providing communication services to one or more end user devices in coverage areas of the CBRS devices, wherein the update includes causing the CBRS devices to provide to the one or more end user devices in the coverage areas, in at least one message, a sequence of radio channels that the end user device of the one or more end user devices is permitted to attach to in an order, the sequence including information identifying a CBRS channel authorized according to the CBRS information and a cellular channel, wherein at least one EMS of the one or more EMSs manages at least one CBRS device of the CBRS devices that is operated by a third party entity distinct from the network operator, and wherein the providing the channel assignments includes providing at least a portion of the channel assignments to the at least one EMS to enable the at least one EMS to update the at least one CBRS device.

A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, the operations comprising:
- obtaining Citizens Band Radio Service (CBRS) information that is generated by Spectrum Access System (SAS) equipment, the CBRS information including a non-use location where CBRS is unavailable;
- predicting a future location for a particular end user device that is operating over a CBRS channel;
- determining that the future location corresponds to the non-use location resulting in a switch determination;
- responsive to the switch determination, providing a switch instruction to cause the particular end user device to continue a communication service via a cellular channel for use at the non-use location;
- and
- providing, in at least one message, information identifying a sequence of radio channels that the particular end user device is permitted to attach to in an order, the sequence including the cellular channel and an authorized CBRS channel according to the CBRS information for use when CBRS is available, wherein the information further identifies a CBRS device operated by a third party entity distinct from a network operator as a handoff target associated with the authorized CBRS channel.
3 more elements
A method,
- comprising:
- receiving, by a processing system including a processor of a base station, one or more channel assignments associated with neighboring base stations, wherein the one or more channel assignments are derived from dynamic channel allocation information obtained by a network server;
- providing, by the processing system, a communication service to a particular end user device over a channel indicated by the one or more channel assignments;
- providing, by the processing system, the particular end user device with neighbor channel information according to the one or more channel assignments corresponding to the neighboring base stations for use in neighbor searches for handoffs to the neighboring base stations wherein the providing the neighbor channel information includes providing, in at least one message, information identifying a sequence of radio channels that the particular end user device is permitted to attach to in an order, the sequence including (i) at least one channel corresponding to the one or more channel assignments associated with the neighboring base stations, (ii) a Citizens Band Radio Service (CBRS) channel authorized according to the CBRS information and associated with at least one CBRS device managed by a third party entity, and (iii) a cellular channel;
- and
- causing, by the processing system, the particular end user device to switch between the CBRS channel and the cellular channel according to a Quality-of-Service requirement associated with an application or service used by the particular end user device.
