POWER OPTIMISATION FOR NETWORK BASED INTERNET PROTOCOL FLOW MOBILITY

摘要

Briefly, in accordance with one or more embodiments, a user equipment (UE) is configured to connect to a network with a multiple access packet data network gateway connection over a wireless wide area network (WWAN) and a wireless local area network (WLAN), enter an idle state for WWAN access, receive a page over the WLAN for WWAN service, connect to the network via the WWAN, and receive the service via the WWAN. A serving gateway (S-GW) is configured to provide a multi-access PDN connection to a UE over a WWAN simultaneously with a WLAN, receive a service to be provided over WWAN access, page the UE via the trusted or untrusted WLAN if the UE is in an idle state, connect with the UE via the WWAN after receiving a response from the UE, and provide the service to the UE via the WWAN.
