A processing system of a cellular network having a processor may receive, from an endpoint device via one of a first radio access infrastructure or a second radio access infrastructure of the cellular network, a request to establish a connection to a packet data network via the cellular network. The processing system may establish, in response to the request, a first session for the endpoint device via the first radio access infrastructure, and a second session for the endpoint device via the second radio access infrastructure of the cellular network, where the connection to the packet data network includes the first session and the second session. The processing system may further configure the first session or the second session for control plane signaling for the connection, and configure the first session, the second session, or both the first session and the second session for user plane communications for the connection.
