METHODS, NETWORK ASSISTANCE NODE, WIRELESS DEVICE, NETWORK NODE AND OPPOSITE NODE, FOR HANDLING DATA COMMUNICATION BETWEEN THE WIRELESS DEVICE AND THE OPPOSITE NODE

摘要

A network assistance node (300), a wireless device (302), a network node (304), an opposite node (306) and methods therein, for handling communication of data between the wireless device and the opposite node over a radio bearer in a cell. When detecting (3:2) that a potential data class is requested which tolerates a certain delay for delivering the data, the network assistance node obtains (3:5) from the network node availability of a potential data bearer dedicated for the potential data class, which availability is dependent on whether a cost related parameter associated with the wireless device fulfils a threshold condition. The network assistance node then reports (3.6) availability of the potential data class to the wireless device and the opposite node, indicating that the potential data bearer is available for data of the potential data class.
