Original Abstract Submitted

Embodiments of the present disclosure relate to path switch between relays and security procedures. A terminal device obtains a selection policy for selecting a RSC from a plurality of RSCs, an RSC of the plurality of RSCs being associated with an indicator for indicating whether the RSC supports a CP security procedure or an UP security procedure. Based on determining that path switching from a source relay terminal device with a source RSC is triggered, the terminal device selects a target RSC based on the selection policy, a source indicator being associated with the source RSC, and a plurality of indicators being associated with the plurality of RSCs. The terminal device selects, for the path switching, a target relay terminal device based on the target RSC. As such, the service continuity after path switching between relays can be improved and delay or disruptions to the service can be avoided.
