Shared spectrum reassignment in a spectrum sharing context
First Claim
Patent Images
1. A shared-spectrum base station comprising:
- a processor; and
a memory coupled with the processor, the memory storing instructions that when executed cause the shared-spectrum base station to;
determine that a renewed license for a shared-spectrum band used by the shared-spectrum base station has been modified from a prior license, the renewed license including one or more modified parameters;
identify one or more target systems covered by a service area of the shared-spectrum base station;
identify, for each mobile device in communication with the shared-spectrum base station, a particular target system of the one or more target systems and a number and timing of handover slots based at least in part on the one or more modified parameters, wherein the number of handover slots corresponds to the number of mobile devices for handover; and
initiate a handover for each of the plurality of mobile devices to the one or more target systems according to the number and timing of handover slots to avoid overload of the one or more target systems with handover requests at one time.

Abstract
The techniques introduced here provide for efficient mass handover from a shared-spectrum wireless communication system (e.g., Licensed Shared Access, Authorized Shared Access, Cloud Spectrum Services, or the like) to a target system (e.g., 3GPP LTE, or the like). The techniques further provide for efficient handling of transitions from one shared-spectrum allocation period to the next shared-spectrum allocation period. Additionally, the techniques provide for efficient handling of multi-operator transitions to re-licensed or re-negotiated shared-spectrum allocations.

18. A method for transitioning a plurality of mobile devices from a first allocation of shared-spectrum bands to a second allocation of shared-spectrum bands provided by one or more shared-spectrum base stations through use of a target band provided by a target base station, the method comprising:
-
receiving an indication, at a target base station, to begin a handover for each of the plurality of mobile devices from one or more shared-spectrum base stations to the target base station during a transition from the first allocation to the second allocation, the indication based at least in part on a renewed license for a shared-spectrum band used by the one or more shared-spectrum base stations being modified from a prior license, the renewed license including one or more modified parameters, and the plurality of mobile devices indicated based at least in part on the modified parameters; transmitting, by the target base station to each of the one or more shared-spectrum base stations, an indication of a handover slot and corresponding timing for each of the plurality of mobile devices; performing the handover for each of the plurality of mobile devices to a target band of the target base station according to the handover slot and corresponding timing for each of the plurality of mobile devices, wherein the target band is different than the first allocation of shared-spectrum bands and the second allocation of shared-spectrum bands; receiving, at the target base station, an indication of availability of shared-spectrum bands in the second allocation of at least one of the one or more shared-spectrum base stations; and performing a handover for mobile devices to the second allocation of shared-spectrum bands of the at least one of the one or more shared-spectrum base stations. - View Dependent Claims (19, 20, 21, 22, 23, 24)
