Title:
NEXT GENERATION RADIO ACCESS NETWORK WIRELESS DEVICE REJECTION INDICATION
Document Type and Number:
WIPO Patent Application WO/2019/138359
Kind Code:
A1
Abstract:
According to an embodiment, a method is performed by a control unit (CU) of a network node. The control unit receives a request message indicating that a wireless device has requested a connection with the network node. The request message is received by the 5 CU via a distribution unit (DU) of the network node. The control unit determines whether to admit or reject the requested connection. In response to determining to reject the requested connection, the control unit transmits a rejection message to the wireless device via the DU. The rejection message indicates that the requested connection has been rejected. The DU may determine that the requested connection has been rejected based on the rejection message or 0 another rejection indication sent by the CU. The DU deallocates resources associated with the rejected wireless device and reallocates the resources.
