1. A method performed by a mobile integrated access and backhaul (IAB) node, the method comprising: monitoring a communication link between communication components of a vehicle and a first gNodeB (gNB), the communication components of the vehicle being separate from the mobile IAB node and configured to communicate with a telecommunication core network via the first gNB; determining that a signal strength of the communication link is below a threshold; scanning a geographical area within a distance of the vehicle for at least one second gNB; establishing communication with at least one of the first gNB or the at least one second gNB; providing the vehicle access to at least one of the first gNB or the at least one second gNB via the mobile IAB node; and sending a transmission to a UE associated with the vehicle indicating that the mobile IAB node has been removed from the vehicle in response to determining that the mobile IAB node has exited a geo-fence defining an area around the vehicle.
