In accordance with embodiments of the present invention, a list of preferred Public Land Mobile Networks (PLMNs) is used by a radio access network (RAN) node for distributing subscriber registrations to respective core network (CN) nodes and, notably, is expanded to also include the Mobile Subscriber Identity Number (MSIN) of subscribers. At least one bit of the MSIN, starting from the most significant bit, is interpreted to indicate the CN node to which a subscriber registration is to be routed. In this way the granularity of the preferred PLMN list is increased and it is thereby possible to steer subscriber registrations to specific core network nodes (e.g., Mobile Switching Centers and/or Serving GPRS Support Nodes) within one CN network operator. |
