Title:
METHOD AND NODE FOR TRANSMITTING CRITICAL INFORMATION IN A WIRELESS NETWORK
Document Type and Number:
WIPO Patent Application WO/2022/260321
Kind Code:
A1
Abstract:
A method for transmitting critical information by a node in a control and user plane separation (CUPS) in a wireless network is provided. The method includes determining, by the node in the CUPS of the wireless network, a retry threshold for retransmission of a Sx message comprising critical information to another node is reached. The method also includes activating, by the node, a message re-transmission timer, in response to determining that there try threshold for the transmission of the Sx message to the another node is reached, and retransmitting, by the node, the Sx message to the another node at exponential intervals of time until an expiry of the message re-transmission timer.
