Conditional handover

A radio access network node, comprising:

• at least one processor;
• and
• at least one memory storing instructions which, when executed by the at least one processor, cause the radio access network node to perform:
• determining a conditional handover configuration for a plurality of target cells and a radio condition for conditional handover of a user equipment (UE) the conditional handover configuration of the plurality of target cells comprising network slice area of service availability information criterion for each of the plurality of target cells;
• adjusting the criterion based on a network slice area of service availability information of the plurality of target cells;
• selecting a preferred target cell based on the criterion;
• and
• transmitting, to the UE, the selection of preferred target cell.

A non-transitory computer-readable medium storing instructions which, when executed by at least one processor of a user equipment, cause the user equipment to perform:

• receiving, from a radio access network node, a conditional handover configuration for a plurality of target cells and a radio condition for conditional handover of the UE for a plurality of target cells,
• receiving, from the radio access network node, an indication that the UE is allowed to select and connect to a preferred target cell from the plurality of target cells;
• selecting the preferred target cell from the plurality of target cells based on network slice area of service availability information for each target cell configured at the UE and the radio condition;
• and
• transmitting, a request to connect to the preferred target cell.
