Fifth Generation (5G) mobile networks utilize network slicing for providing diverse services over a shared infrastructure. User Equipments (UEs) can access multiple slices concurrently to avail services requiring different Quality of Service (QoS). Third Generation Partnership Project (3GPP) 5G stipulates that all slices supported for a given UE should be deployed homogeneously over its Registration Area (RA) for ensuring slice availability during mobility. 3GPP also prescribes mechanisms such as multi‐connectivity for improving mobility robustness in heterogeneous networks. However, to the best of our knowledge, the role of multi‐connectivity in the context of network slicing has not been well‐explored. In this paper, we propose using multi‐connectivity for improving the availability of network slices. 1
