Abstract:
1. A method for improving scan time in a co-banded mobile communication device comprising: maintaining a set of records within a data store of a co-banded mobile communication device, wherein the set of records include a plurality of communication rasters that represent an overlap between frequency bands used by different access technologies supported by the mobile communication device; scanning frequency bands of a first access technology for occupied communication rasters associated with the first access technology, wherein the first access technology is not a Global System for Mobile communication (GSM) access technology; for each occupied communication raster found when the frequency bands of the first access technology are scanned, recording in the set of records an indication that the communication raster is occupied; and subsequent and responsive to scanning frequency bands of the first access technology, scanning frequency bands of a second access technology communication rasters associated with the second access technology, wherein the scanning for the second access technology skips those communication rasters indicated as occupied within the set of records and only those which have been scanned within a preselected time period from scanning frequency bands of the second access technology, as indicated in the set of records.
