The method includes transmitting to a mobile network a capability message indicating that the WCD does not support any coverage enhancement (CE) mode. The method also includes determining whether a condition is satisfied, which comprises determining whether the vehicle is parked. The method further includes as a result of determining that the condition is satisfied, informing the mobile network that the WCD supports a CE mode. ## Claims ### Claim 1 A method for providing enhanced network coverage for a vehicle that is equipped with a wireless communication device, WCD (WCD), the method comprising: transmitting to a mobile network a capability message indicating that the WCD does not support any coverage enhancement (CE) mode; determining whether a condition is satisfied, wherein determining whether the condition is satisfied which comprises determining whether the vehicle is parked; and as a result of determining that the condition is satisfied, informing the mobile network that the WCD supports a CE mode. ### Claim 2 (depends on 1) The method of claim 1, wherein the capability message is an RRC a Radio Resource Control (RRC) message destined for a base station of the mobile network, or the capability message is a Non-Access Stratum (NAS) message destined for a control plane (CP) node of the mobile network. ### Claim 3 (depends on 1) The method of claim 1, wherein determining whether the condition is satisfied further comprises determining whether the vehicle is located in an area with poor network coverage. ### Claim 4 (depends on 3) The method of claim 3, wherein determining whether the vehicle is located in an area with poor network coverage comprises determining a received signal strength of a signal transmitted by a base station and determining whether the received signal strength is less than a threshold. ### Claim 5 (depends on 3) The method of claim 3, wherein the condition is satisfied when the vehicle is parked and the vehicle is located in an area with poor network coverage. ### Claim 6 (depends on 1) The method of claim 1, wherein the step of determining whether the condition is satisfied is performed by an app (122) running on processing circuitry within the vehicle. ### Claim 7 (depends on 1) The method of claim 1, wherein informing the mobile network that the WCD supports a CE mode comprises triggering the WCD to transmit to the mobile network a capability message comprising information specifying that WCD supports a CE mode. ### Claim 8 (depends on 7) The method of claim 7, wherein informing the mobile network that the WCD supports the CE mode further comprises the app enabling the WCD to support the CE mode as a result of the app determining that the condition is satisfied and prior to triggering the WCD to transmit the capability message to the mobile network. ### Claim 9 (depends on 1) The method of claim 1, wherein informing the mobile network that the WCD supports a CE mode comprises: enabling support of the CE mode in the WCD; and triggering the WCD to re-register to mobile network. ### Claim 10 (depends on 9) The method of claim 9, wherein informing the mobile network that the WCD supports a CE mode further comprises the app, prior to triggering the WCD to re-register with the mobile network, triggering the WCD to de-register with the mobile network. ### Claim 11 (depends on 6) The method of claim 6, wherein determining whether the condition is satisfied further comprises the app determining whether the app is able to communicate with a server, wherein the condition is satisfied when the app determines that it is not able to communicate with the server and the app determines that the vehicle is parked. ### Claim 12 (depends on 11) The method of claim 11, further comprising the app triggering the WCD to inform the mobile network that the WCD supports a CE mode as a result of the app determining that the condition is satisfied. ### Claim 13 (depends on 12) The method of claim 12, wherein triggering the WCD to inform the mobile network that the WCD supports a CE mode comprises the app using AT-Command or an application programming interface (API) to send a control plane, CP, message to the WCD. ### Claim 14 (depends on 1) The method of claim 1, further comprising: determining that the condition is no longer satisfied; and as a result of determining that the condition is no longer satisfied, informing the mobile network that the WCD does not support any CE mode. ### Claim 15 (depends on 1) The method of claim 1, wherein the WCD is located on or in the vehicle. ### Claim 16 A wireless communication device (WCD), the WCD comprising: a transmitter; and processing circuitry coupled to the transmitter, wherein the WCD is configured to: employ the transmitter to transmit to a mobile network a capability message indicating that the WCD does not support any CE mode; determine whether a condition is satisfied by performing a process that includes determining whether a vehicle in which the WCD is equipped is parked; and as a result of determining that the condition is satisfied, inform the mobile network that the WCD supports a CE mode. ### Claim 17 (depends on 16) The WCD of claim 16, wherein the process further includes determining whether the vehicle is located in an area with poor network coverage. ### Claim 18 (depends on 16) A vehicle comprising the WCD of claim 16. ### Claim 19 (depends on 1) A non-transitory computer readable medium storing computer program comprising instructions which when executed by processing circuitry causes the processing circuitry to perform the method of claim 1. ### Claim 20 (canceled)
