and one or more processors to execute the instructions to receive channel-availability information that indicates one or more channels supported by and available to the user device; store the channel-availability information; scan one or more channels indicated in the channel-availability information; and connect to a network using one of the one or more channels. ## Claims ### Claim 1 A user device comprising: a communication interface; one or more memories to store instructions; and one or more processors to execute the instructions to: receive, via the communication interface, channel-availability information that indicates one or more channels supported by and available to the user device; store the channel-availability information; scan one or more channels indicated in the channel-availability information; and connect, via the communication interface, to a network using one of the one or more channels. ### Claim 2 (depends on 1) The user device of claim 1, wherein the one or more channels pertain to one or more channels supported by the user device and available to the user device in a current location of the user device. ### Claim 3 (depends on 1) The user device of claim 1, wherein the one or more channels are less than a total number of channels supported by the user device, and wherein the one or more channels pertain to one or more channels supported by the user device and available to the user device in a location other than the current location of the user device. ### Claim 4 (depends on 1) The user device of claim 1, wherein the one or more processors further execute the instructions to: identify a connection loss to the network; and adjust a frequency in which the user device scans based on the channel-availability information. ### Claim 5 (depends on 4) The user device of claim 4, wherein, when adjusting, the one or more processors further execute the instructions to: recognize that a number of supported and available channels is high based on a comparison to a threshold value; and increase the frequency in which the user device scans relative to a default frequency. ### Claim 6 (depends on 4) The user device of claim 4, wherein, when adjusting, the one or more processors further execute the instructions to: recognize that a number of supported and available channels is low based on a comparison to a threshold value; and decrease the frequency in which the user device scans relative to a default frequency. ### Claim 7 (depends on 1) The user device of claim 1, wherein the user device comprises a mobile communication device having telephone capabilities. ### Claim 8 A method comprising: receiving channel-availability information that indicates one or more channels supported by and available to a user device in a location; storing the channel-availability information; scanning one or more channels indicated in the channel availability information when the user device is located in the location; and connecting to a network using one of the one or more channels. ### Claim 9 (depends on 8) The method of claim 8, further comprising: identifying a connection loss to the network; and adjusting a frequency in which the user device scans based on the channel-availability information. ### Claim 10 (depends on 9) The method of claim 9, further comprising: recognizing that a number of supported and available channels is high based on a comparison to a threshold value; and increasing the frequency in which the user device scans relative to a default frequency. ### Claim 11 (depends on 9) The method of claim 9, wherein the detecting comprises: recognizing that a number of supported and available channels is low based on a comparison to a threshold value; and decreasing the frequency in which the user device scans relative to a default frequency. ### Claim 12 (depends on 8) The method of claim 8, further comprising: transmitting a channel-availability request that comprises location information and a device identifier pertaining to the user device. ### Claim 13 (depends on 8) The method of claim 8, further comprising: identifying a connection loss to the network; and ceasing to scan, in response to the identifying, for a supported channel until a triggering event occurs. ### Claim 14 (depends on 13) The method of claim 13, wherein the triggering event comprises that the user device moves a predetermined distance from a location that the connection loss occurred. ### Claim 15 (depends on 8) The method of claim 8, further comprising: selecting channel-availability information based on location information and a device identifier associated with the user device, wherein the selecting comprises: identifying one or more channels and one or more access technologies supported by the user device; identifying one or more channels and one or more access technologies available to the user device in correspondence to the location information; and selecting one or more channels and one or more access technologies that are available to the user device in correspondence to the location information and is/are supported by the user device.
