IMPROVED RESUMPTION OF PDN CONNECTIONS FOR DEVICES REGAINING WLAN CONNECTIVITY |
摘要 |
Technology that allows PDN connections for a UE to be resumed efficiently after WLAN connectivity is lost and then regained are disclosed. A UE can have a multi-legged or multi-access packet-data-network (PDN) connection that is used to communicate with a WLAN and with an eNB. When WLAN connectivity is lost, the UE can send a WLAN-connectivity-loss communication to a PDN-GW via the eNB. A TWAG can also detect that the UE's WLAN connectivity has been lost and can send a suspension communication to the PDN-GW. The TWAG can also store PDN context information for the UE for a predefined period of time. When the UE regains WLAN connectivity, the UE can send a WLAN-link-control-protocol (WLCP) communication to the TWAG indicating that the UE wishes to resume one or more PDN connections that were previously suspended. |
