1. A terminal device comprising:
at least one processor; and
at least one non-transitory memory including computer program code;
the at least one memory and the computer program code configured to, with the at least one processor, cause the terminal device at least to perform:
maintaining, in said at least one memory, a configuration for a radio resource control inactive state of the terminal device, wherein the configuration comprises at least information on a radio access network notification area assigned for the terminal device;
acquiring information on an expected latency of incoming radio resource control messages within the radio access network notification area; and
in response to triggering a radio resource control connection resume procedure, performing the following:
transmitting a radio resource control connection resume request to a target access node,
starting a timer defined based on the information on the expected latency of the radio resource control messages,
in response to the timer expiring, initiating monitoring of incoming radio resource control messages, and
in response to receiving a radio resource control connection resume message from the target access node, activating a radio resource control connected state of the terminal device.
