Zusammenfassung:An apparatus and method for enabling communication between a "non-supporting" User Equipment (UE) 109 and one of several core networks 101, 102, 103 sharing a radio access network (RAN) which includes a Home Node B (HNB) 105, comprises: configuring a look-up table 108 which links the PLMN code included in the IMSI of a UE with identities of one or more of the core networks to which a wireless communication unit is allowed access and inspecting the look-up table 108 to identify a core network to which a UE requesting a connection is allowed access, and forwarding the request for connection to the identified core network. The look-up table 108 may be pre-provisioned with lists of UE identities versus core networks to which each UE is allowed access or it may he compiled by a round-robin routing of a connection request to each core network in turn until one accepts the UEs request for connection, whereupon the look-up table is populated with a list linking wireless communication unit identities with those core networks that allow access. For use in a shared radio access network employing a Multiple Operator Core Network (MOCN).
