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.

Description

technical field [0001] Embodiments herein relate generally to a source core network node and methods in the source core network node. More specifically, embodiments herein relate to public land mobile network (PLMN) selection when handover (HO) to a target shared location. Background technique [0002] In a typical communication network (also known as, for example, a wireless communication system, wireless communication network, communication network or communication system), a user equipment (UE) communicates with one or more core networks (CN) via a radio access network (RAN) communication. [0003] User equipment is a mobile terminal by which a subscriber can access services provided by the operator's network and outside the operator's network to which the operator's radio access network and core network provide access (for example, access to the Internet) Serve. The user equipment may eg be a communication device such as a mobile phone, cellular phone, smartphone, tab...
