Patent ID: 11115887

Abstract:
The present invention provides a base station, a user equipment (UE) and a method executed by the base station. The method executed by the base station comprises: broadcasting to the UE that the base station supports connectivity to a first core network and a second core network, a communication interface between the first core network and the base station being different from a communication interface between the second core network and the base station; receiving a selection of the UE to one of the first core network and the second core network; and initiating, according to the received selection of the UE, connection establishment to the core network selected by the UE. The technical solution provides a core network selection method for a base station (e.g., eLTE eNB) simultaneously supporting two different core networks, so as to correspondingly determining a network interface used for communication with the selected core network, thereby achieving normal communication between the UE and the core network.
