  • Patent number: 12213062
    Abstract: The present disclosure provides a method and an apparatus for notifying an application function node about a reliable data service (RDS) configuration of a network. The method implemented at an exposure function node includes: obtaining an RDS configuration of a terminal device; determining an RDS capability of a network; and sending a message including information about the RDS capability of the network to the application function node, if the RDS capability of the network is changed. The RDS capability of the network indicates whether the network supports the RDS. The method implemented at an application function node includes: receiving, from an exposure function node, a message including information about the RDS of the network, if the RDS capability of the network is changed. Data transmissions of the application function node with improper configuration may be avoided.
