Abstract

See full text

Embodiments herein relate to a network node for handling a Radio Access Network, (RAN) context information of a wireless device in a cell served by the network node in a wireless communications network. The network node stores the RAN context information of the wireless device when the wireless device is no longer in a connected state in the cell. When the wireless device has returned to a connected state in the cell, the network node receives information indicating a RAN context information from the wireless device. Also, the network node transmits, to the wireless device, information indicating that the wireless device is to use the indicated RAN context information in the cell when the indicated RAN context information is such that it can be reused with the RAN context information of the wireless device previously stored by the network node. Embodiments of the network node are also described.
