Abstract:
1. A method in a radio access network (RAN) device for coordinating the registration of a mobile terminal that does not support network sharing in circuit-switched (CS) and packet-switched (PS) domains of a multi-operator core network with multiple core networks, the method comprising the steps of: receiving, from a device in a first core network, a notification message indicating the requirement of coordinated CS and PS registrations for the mobile terminal; selecting, based on a global permanent identity associated with the mobile terminal, a second core network for coordinated CS and PS registrations; and, sending, to a device in the selected second core network, at least one registration message for coordinated CS and PS registrations for said mobile terminal, whereby said mobile terminal is registered with the CS and PS domains of said second core network without input from said mobile terminal.
