Abstract:
A user device includes and maintains a geolocation list (GLL) including sets of information corresponding to Citizens Broadband radio Services Devices (CBSDs). The GLL stored in the user device contains entries corresponding to the areas most recently visited by the UE, each entry including location information of a CBSD. User devices typically frequent a limited set of the same areas repetitively. Thus this maintained relatively small list provides the UE with a highly relevant set of information which can be quickly accessed without additional wireless signaling and the additional power loss associated with a typical search. When the UE desires to find and connect to a CBSD, the UE first searches its GLL for a CBSD providing coverage in its currently located area. However, if GLL search does not identify a CBSD, then the UE sends a request to a geolocation server for active CBSDs.
