Abstract:
A method of controlling routing in a cellular communication system serving user equipment and having a radio access network operably coupled to each core domain of a plurality of core network domains, wherein each core network domain of the plurality of core network domains switches messages in a manner different from the other core network domains of the plurality of core network domains, the method comprising the steps of:receiving, by the radio access network, network services, applications, and domain information; receiving, by the radio access network, a message from the user equipment; selecting, by the radio access network, a core network domain from among the plurality of core network domains for a routing of the message based on at least one of a user equipment preference and a radio access network preference; and routing, by the radio access network, the incoming message to the core network domain selected by the radio access network.
