Title:
METHOD AND USER EQUIPMENT (UE) FOR RECONNECTING RRC CONNECTION WITH RADIO ACCESS NETWORK (RAN) NODE
Document Type and Number:
WIPO Patent Application WO/2018/230980
Kind Code:
A1
Abstract:
Accordingly the embodiments herein provide a method for reconnecting a Radio Resource Control (RRC) connection with a Radio Access Network (RAN) node by a User Equipment (UE) in a wireless communication system. The method includes transmitting a message 3 (MSG3) of a random access procedure on Signaling Radio Bearer 0 (SRB0) for reconnecting the RRC connection. The MSG3 is a request message to the RAN node with set of connection parameters. Further, the method includes receiving a message 4 (MSG4) of the random access procedure from the RAN node. The MSG4 is received on a SRB0 or a Signaling Radio Bearer 1 (SRB1). Furthermore, the method includes transmitting a message 5 (MSG5) on the SRB1 to RAN node for reconnecting RRC connection. The proposed method can be used to mitigate a replay attack on the UE in a inactive state using a nonce and a wait time interval.
