Supporting mobility during low activity state

An apparatus, comprising:

• at least one processor;
• and
• at least one memory including computer program code,
• wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to
• transmit, by a user device in a low activity state a type of the low activity state being according to an anchor access node, a random-access message to a network node providing a target cell of a cell reselection;
• in response to receiving a random-access response for the random access message from the network node providing the target cell, transmit, to the network node providing the target cell, a radio connection reactivation request, the reactivation request comprising an indication of the anchor access node of the user device, and
• in response to the radio connection reactivation request, receive a radio connection reactivation message indicating a radio connection reactivation to the anchor access node as a logical link associated with a radio link provided by the target cell of the cell reselection, or receive an inactivation message.

An apparatus comprising:

• at least one processor;
• and
• at least one memory including computer program code,
• wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to
• receive, by an anchor access node for a user device, a radio connection reactivation request in relation to a cell reselection procedure and during a state transition of the user device to a connected state, and
• carry out a radio connection reactivation, wherein the radio connection to the user device is reactivated as a logical link associated with a radio link provided by a target cell of the cell reselection, or transmitting an inactivation message.

A distributed computing system, comprising:

• a radio node, configured to:
• receive a radio connection reactivation request in relation to a cell reselection procedure and during a state transition of the user device to a connected state, and configured to communicate the radio connection reactivation request to a server and to the user device, and
• the server configured to:
• carry out a radio connection reactivation, wherein the radio connection is reactivated as a logical link associated with a radio link provided by a target cell of the cell reselection and communicate the radio connection reactivation to the radio node or communicate a radio connection inactivation message to the radio node.
