SYSTEM, DEVICES, AND METHODS FOR INTERWORKING BETWEEN A LEGACY 3GPP MOBILE TELECOMMUNICATIONS NETWORK (4G) AND A NEXT GENERATION NETWORK (5G)

摘要

A system is disclosed comprising: a first type of communication network that comprises a radio access network and a first core network; and second type of communication network comprising second core network. The first type of communication network and the second type of communication network each operate in accordance with a different respective set of communication standards. An MME of the first core network is configured to determine whether a communication device that is located in a cell of the radio access network is capable of using (or entitled to use) a service that is provided via the second type of communication network. The MME is configured to transmit a message, towards the second core network, to initiate interworking between the first core network and the second core network for the provision of the service.
