  • Patent number: 9693275
    Abstract: For traffic offload via a local network, a MME may obtain from a HSS, subscription data including SIPTO related permissions defined on APN basis that indicate SIPTO prohibited, indicate SIPTO allowed excluding SIPTO via Local Network (SIPTO@LN), and/or indicate SIPTO allowed including SIPTO@LN. Then, the MME may obtain information about one or more local Gateways (GWs) capable of offloading selected traffic, such information indicating which of the one or more local GWs provides access to which Packet Data Networks (PDNs), with each PDN being identified by its associated APN. Finally, the MME may process PDN connections and/or PDN disconnections in order to support offloading of the selected traffic.

  • Patent number: 9179383
    Abstract: There is provided a method for determining a handover. The method may comprise: determining, by User Equipment (UE), whether a timer is running, wherein the UE has accessed multiple Radio Access Technologies (RATs); if the timer is not running, performing, by the UE, a handover of a data traffic, which has been routed onto a Wireless LAN (WLAN), to an original RAT; and if the timer is running, not performing, by the UE, the handover of the data traffic, which has been routed onto the WLAN, to the original RAT. The data traffic may be been routed onto the WLAN as a result of Circuit Switched Fall-Back (CSFB) or 3GPP RAT mobility.

  • Patent number: 9173152
    Abstract: A method and a server are described for supporting handover by a network node in a mobile communication system. A message related to a handover, including a first parameter indicating a cause for the handover, is received. A handover command message is transmitted to a first base station for a terminal to perform a handover to a second base station, when the network node determines that handover is needed based on the cause. A status report message including a second parameter indicating whether or not the cause for handover is solved is received. A reverse handover request message is transmitted to the second base station for the terminal to perform reverse handover to a target base station, when the network node determines that a reverse handover is needed. The network node determines whether the handover or the reverse handover is needed.
