The method provided in this embodiment improves the capabilities of automatic driving and ADAS of electric vehicles. The method can be applied to vehicle networking, such as V2X, LTE-V, V2X, etc. The method includes receiving, from the mobile device, an indication of a requirement for transmission resources, comprising at least an indication that the resources are required with a periodicity, transmitting, to the mobile device, an assignment of a first scheduling configuration for the device-to-device connection, transmitting, to the mobile device, an indication to begin use of periodically recurring radio resources, and handing over responsibility for providing radio resources for the device-to-device connection from the network node to a target network node such that the availability of radio resources with the periodicity is substantially maintained.
