Plmn selection at handover to a target shared location being shared between core network operators

Abstract

This disclosure relates to Network Sharing and in particular to a source core network node 410s for handling handover of a user equipment 401 from a source location 400s to a target shared location 400t and a method performed in that source core network node 410s for handling handover of a user equipment 401 from a source location 400s to a target shared location 400t, which target shared location 400t is shared between core network operators. The method comprises receiving 501, 601, from a source radio access network node 405s, a request for handover of the user equipment 401 from the source location 400s to the target shared location 400t, which request comprises information indicating a first target Public Land Mobile Network, PLMN served at the target shared location 400t and intended to serve the user equipment 401 at the target shared location 400t; obtaining 502, 602 information indicating a candidate target PLMN associated with the user equipment 401, which candidate target PLMN is served at the target shared location 400t; and determining 503, 603, based on the received information indicating the first target PLMN and the obtained information indicating the candidate target PLMN, that the first target PLMN shall be replaced by a second target PLMN to serve the user equipment 401 in the target shared location 400t, which second target PLMN is served at the target shared location 400t.
