Claim 4:
5. An information obtaining method, applied to a network node, wherein the method comprises:
receiving the indication information sent by the terminals,
the indication information is used to indicate that the terminal detects an FRF, the FRF is a failure of a fast recovery that is of a first link and that is initiated through a second link after a first link failure, the first link is a link between the terminal and a first node, and the second link is a link between the terminal and a second node;
wherein the first link is the link between the terminal and a master cell group (MCG) of the master node, and the second link is the link between the terminal and a secondary cell group (SCG) of the secondary node; and
the indication information is further used to indicate information related to the FRF, wherein the information related to the FRF comprises at least an FRF type;
wherein the FRF type comprises at least one of the following:
the terminal having not received an MCG reconfiguration message within a preset time;
a failure of the terminal to receive the MCG reconfiguration message on a signaling radio bearer (SRB) SRB 1 and/or a split SRB 1S;
an integrity protection failure of the SRB 1 and/or the SRB 1S;
a lack of capability of the terminal to satisfy the received MCG reconfiguration;
a failure of a random access procedure initiated by the terminal based on the received MCG reconfiguration message;
a failure of the terminal to report MCG link failure information;
a failure of the terminal to find a suitable MCG to initiate an FR; or
an SCG link failure of the terminal in an FR procedure.
