Abstract: 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.

Abstract: Systems and methods of sharing channel information between co-located radio nodes are provided. In one exemplary embodiment, a method performed by a second radio node (111, 200, 300a, b, 1111) of sharing channel information between a first radio node (101, 500, 600a, b, 1101) and the second radio node that are co-located (107) may include obtaining (403), by the second radio node, first channel information characterizing a communication channel (105a-c) between a third radio node (121, 1121) and the first radio node in a first frequency band. Further, the method may include using (405), by the second radio node, the first channel information for communication with the third radio node or a fourth radio node (123) in a second frequency band.

Abstract: Methods and apparatus enable a femto radio base station (28f), initially connected to a first or default radio network controller node (261), to be redirected/reconnected to a second or correct radio network controller node (262) for use as an active radio network controller node for the femto radio base station (28f). The redirection/reconnection is accomplished by using location-indicative information obtained from a user equipment unit (30) which is in radio communication with the femto radio base station (28f). The technique of redirection is particularly valuable when the femto radio base station (28f) does not have its own receiver for ascertaining the radio access network (RAN) environment.
