A wireless device, a network node, a core node and methods for handling radio communication of data between the wireless device and the network node in a wireless network. The network node transmits system information related to availability of a potential data bearer dedicated for data tolerating a certain delivery delay, which is received by the wireless device in idle or inactive mode. The wireless device determines whether the potential data bearer is available, based on the system information. When available, the wireless device initiates a transition from idle/inactive mode to connected mode and communicates the data over the potential data bearer. When the potential data bearer is unavailable, the wireless device stays in the idle/inactive mode. When the data is downlink data, the core node sends a paging message indicating a potential data class.
