communication systems using wireless links for non-selective communication, e.g. wireless extensions H04M1/72) ## Abstract A mobile computing device comprising: a wireless communications interface; a controller configured to: detect a scan condition to scan a foreign channel while connected to a home base station; implement a scanning sequence including: (a) a plurality of portions of a predefined scan interval for scanning the foreign channel, and (b) an intermediate home channel dwell period scheduled between each of the plurality of portions of the predefined scan interval; and during each intermediate home channel dwell period, return to the home base station to receive data packets buffered during a preceding portion of the predefined scan interval. ## Claims ### Claim 1 A mobile computing device comprising: a wireless communications interface configured to connect to a network deployed by a plurality of base stations; a controller for the wireless communications interface, the controller configured to: detect a scan condition to scan a foreign channel while connected to a home base station on a home channel; implement a scanning sequence including: (a) a plurality of portions of a predefined scan interval for scanning the foreign channel, and (b) an intermediate home channel dwell period scheduled between each of the plurality of portions of the predefined scan interval; and during each intermediate home channel dwell period, return to the home channel to receive data packets buffered at the home base station during a preceding portion of the predefined scan interval. ### Claim 2 (depends on 1) The mobile computing device of claim 1, wherein the plurality of portions of the predefined scan interval span the predefined scan interval. ### Claim 3 (depends on 1) The mobile computing device of claim 1, wherein the scanning sequence is configured to span multiple iterations of the scan interval. ### Claim 4 (depends on 1) The mobile computing device of claim 1, wherein the scan condition comprises detecting that the device is configured to perform a passive scan for the foreign channel. ### Claim 5 (depends on 4) The mobile computing device of claim 4, wherein the predefined scan interval is a beacon interval at which a beacon signal is emitted on the foreign channel. ### Claim 6 (depends on 1) The mobile computing device of claim 1, wherein the controller is configured to return to the home channel for a home channel dwell time to receive data packets buffered at the home base station after completion of the scanning schedule. ### Claim 7 (depends on 1) The mobile computing device of claim 1, wherein the controller is configured to, after each scan period: determine whether a foreign access point corresponding to the foreign channel is identified; and when the foreign access point is identified, terminate the scanning schedule. ### Claim 8 A method comprising: detecting a scan condition to scan a foreign channel while connected to a home base station on a home channel; implementing a scanning sequence including: (a) a plurality of portions of a predefined scan interval for scanning the foreign channel, and (b) an intermediate home channel dwell period scheduled between each of the plurality of portions of the predefined scan interval; and during each intermediate home channel dwell period, returning to the home channel to receive data packets buffered at the home base station during a preceding portion of the predefined scan interval. ### Claim 8 (depends on 7) The method of claim 7, wherein the scanning schedule is configured to span multiple iterations of the scan interval. ### Claim 9 (depends on 8) The method of claim 8, wherein the plurality of portions of the predefined scan interval span the predefined scan interval. ### Claim 11 (depends on 8) The method of claim 8, wherein detecting the scan condition comprises detecting that a passive scan is to be performed on the foreign channel. ### Claim 12 (depends on 11) The method of claim 11, wherein the predefined scan interval is a beacon interval at which a beacon signal is emitted on the foreign channel. ### Claim 13 (depends on 8) The method of claim 8, further comprising returning to the home channel for a home channel dwell time to receive data packets buffered at the home base station after completion of the scanning schedule. ### Claim 14 (depends on 8) The method of claim 8, further comprising, after each scan period: determining whether a foreign access point corresponding to the foreign channel is identified; and when the foreign access point is identified, terminating the scanning schedule. ### Claim 14 (depends on 13) The non-transitory machine-readable medium of claim 13, wherein the scanning schedule is configured to span multiple iterations of the scan interval. ### Claim 15 A non-transitory machine-readable medium storing instructions which when executed, configure a controller of device to: detect a scan condition to scan a foreign channel while connected to a home base station on a home channel; implement a scanning sequence including: (a) a plurality of portions of a predefined scan interval for scanning the foreign channel, and (b) an intermediate home channel dwell period scheduled between each of the plurality of portions of the predefined scan interval; and during each intermediate home channel dwell period, return to the home channel to receive data packets buffered at the home base station during a preceding portion of the predefined scan interval. ### Claim 16 (depends on 15) The non-transitory machine-readable medium of claim 15, wherein the plurality of portions of the predefined scan interval span the predefined scan interval. ### Claim 18 (depends on 15) The non-transitory machine-readable medium of claim 15, wherein the scan condition comprises detecting that the device is configured to perform a passive scan for the foreign channel. ### Claim 19 (depends on 18) The non-transitory machine-readable medium of claim 18, wherein the predefined scan interval is a beacon interval at which a beacon signal is emitted on the foreign channel. ### Claim 20 (depends on 15) The non-transitory machine-readable medium of claim 15, wherein the instructions further configure the controller to return to the home channel for a home channel dwell time to receive data packets buffered at the home base station after completion of the scanning schedule. ### Claim 21 (depends on 15) The non-transitory machine-readable medium of claim 15, wherein instructions further configure the controller to, after each scan period: determine whether a foreign access point corresponding to the foreign channel is identified; and when the foreign access point is identified, terminate the scanning schedule.
