Abstract

See full text

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.
