Abstract
In one example aspect, a method of handover is provided. The method comprises determining a first handover candidate list for a first user equipment (UE). The first UE is connected to a first cell and is associated with a first network slice. In response to a determination that the first handover candidate list indicates no valid candidate target cells for handover of the first UE, the method comprises determining a second handover candidate list for a second UE, wherein the second UE is connected to the first cell, and causing the second UE to handover to a second cell indicated in the second handover candidate list.

A method of handover, the method comprising:
- determining a first handover candidate list for a first user equipment, UE, wherein the first UE is connected to a first cell and is associated with a first network slice;
- and
- in response to a determination that the first handover candidate list indicates no valid candidate target cells for handover of the first UE:
- determining a second handover candidate list for a second UE, wherein the second UE is connected to the first cell;
- causing the second UE to handover to a second cell indicated in the second handover candidate list;
- determining that the first handover candidate list indicates at least one further cell, and the first network slice is not associated with the at least one further cell.
Apparatus for handover, the apparatus comprising processing circuitry and a memory, the memory containing instructions executable by the processing circuitry such that the apparatus is operable to:
- determine a first handover candidate list for a first user equipment, UE, wherein the first UE is connected to a first cell and is associated with a first network slice;
- and
- in response to a determination that the first handover candidate list indicates no valid candidate target cells for handover of the first UE:
- determine a second handover candidate list for a second UE, wherein the second UE is connected to the first cell;
- cause the second UE to handover to a second cell indicated in the second handover candidate list;
- determine that the first handover candidate list indicates at least one further cell, and the first network slice is not associated with the at least one further cell.
