The present disclosure relates to methods, systems and apparatuses for transferring a user equipment (UE) connected to a first network (e.g., a LTE network) to a second network (e.g., a Wireless Local Area Network, or WLAN). In particular, the present disclosure teaches methods, systems and apparatuses for selecting and connecting the UE to a gateway (e.g., an evolved packet data gateway (ePDG)) and a network apparatus (e.g., a packet data network gateway (PGW)). By sending the IP address of the gateway and the network apparatus to the UE before the UE disconnects from the first network (e.g., via a Protocol Configuration Option (PCO) message), the UE is able to connect to the gateway and network apparatus directly without consulting a DNS server or a Home Subscriber Server. These techniques can be useful when no DNS server is available and in virtualized, cloud-based networks. |

1. A network apparatus in a core network, comprising:
an interface configured to communicate with a user equipment (UE) via a wireless network; and a processor in communication with the interface; the network apparatus configured to:
receive information from the UE, wherein the UE is connected to the network apparatus via a first network,determine, based on the received information, a list of available gateways that can serve the UE if the UE connects to a second network, wherein the first network and the second network employ different access technologies;identify a candidate gateway out of the list of available gateways; andsend a network address associated with the candidate gateway to the UE via the first network. |
