APPARATUSES AND METHODS THEREIN FOR ENABLING ESTABLISHMENT OF A CONNECTION BETWEEN A WIRELESS COMMUNICATIONS DEVICE AND A CORE NETWORK

摘要

A method performed by a radio network node for enabling establishment of a connection between a wireless communications device and a core network, which network node and wireless communications device operate in a wireless communications network comprising the core network. The network node obtains (402) a request from the wireless communications device to establish a connection to a first core network node comprised in the core network. The first core network node is not available for connection to the wireless communications device. The network node provides (403) the wireless communications device with a rejection of the request to establish the connection to the first core network node, which rejection comprises an indication to initiate a Tracking Area Update, TAU.
