20120265888 | METHOD AND APPARATUS FOR GATEWAY SESSION ESTABLISHMENT - A method for deploying a policy from a 3GPP core network to a non-3GPP access network. The policy relates to a connection established from a mobile terminal to the 3GPP core network via the non-3GPP access network. A local IP address acquired by the mobile terminal during establishment of the connection is received at the 3GPP core network. At the 3GPP core network, establishment of a policy control session is initiated from the 3GPP core network to the non-3GPP access network. The received local IP address is used to determine the non-3GPP access network used for the connection with reference to shared IP addressing information. At the 3GPP core network, the policy is provided to the non-3GPP access network using the policy control session established as a result of the policy control session initiation step. The policy is for deployment in the non-3GPP access network in relation to the established connection. | 10-18-2012 |

20140044098 | METHOD AND APPARATUS FOR ESTABLISHING A PDN CONNECTION - A method for use in establishing a packet data network, PDN, connection from a user equipment or UE, to a 3GPP core network via a non-3GPP access network. The method comprises receiving at the non-3GPP access network a request to establish the PDN connection; communicating with the 3GPP core network to establish a tunnel for the PDN connection between the non-3GPP access network and the 3GPP core network and to assign an IP address for the tunnel, which tunnel IP address is used subsequently by the non-3GPP access network to distinguish between the new PDN connection tunnel and at least one other such PDN connection tunnel already established for the UE, wherein the 3GPP core network is responsible for assigning the IP address, and sending address information from the non-3GPP access network to the 3GPP core network. | 02-13-2014 |
20140071907 | Method and Apparatus for Handling PDN Connections - A method and apparatus for handling Packet Data Network (PDN) connections between a 3GPP core network node and a User Equipment (UE) via a non-3GPP access network. The UE sends to a gateway node in the non-3GPP access network a first message requesting establishment of a PDN connection. The UE obtains a key associated with the PDN connection and subsequently sends to the gateway node data packets relating to the PDN connection, each data packet including the key. The key allows the gateway node to identify the PDN connection even when multiple PDN connections are used by the UE. | 03-13-2014 |
20140071969 | Method and Apparatus for Establishing and Using PDN Connections - A method is described of establishing and/or using a plurality of packet data network connections between a user equipment and a 3GPP core network via a gateway node in a non-3GPP access network, comprising using a different device identifier for each packet data network connection of the plurality, or at least for each packet data network connection of the plurality that is associated with the same IP address, to distinguish between the packet data network connections of the plurality or to allow such a distinction to be made, wherein the device identifier used to distinguish between the packet data network connections of the plurality is a device identifier associated with the user equipment, or a device identifier associated with the gateway node in the non-3GPP access network, or a combination of these. The device identifier may be a MAC address. | 03-13-2014 |

20140153559 | METHOD AND APPARATUS FOR SELECTING A GATEWAY NODE - A method for selecting a gateway node for a terminal which connects to its registered domain via an access domain and, in a predetermined scenario, an intermediate domain, the access domain having an associated domain name system arranged to return an address of a gateway node based on a domain name system query. The method includes using a first part of such a query to identify the registered domain of the terminal to the domain name system and a second part of the query to indicate to the domain name system that it should use a predetermined mapping to return the address of a gateway node based on the query, the predetermined mapping being one which returns an address of a gateway node either in the registered domain or in an intermediate domain based on the registered domain identified in the query and on the access domain. | 06-05-2014 |

20140341138 | Deferred Address Allocation of IPV4 or IPV6 in Case of Interworking Between Non-3GPP Access and Evolved Packet Core - The application relates to IP address allocation in the context of a user equipment UE connecting to the Evolved Packet Core as standardised by 3GPP, in particular over the S2a interface, where there is a GPRS Tunneling Protocol (GTP) or Proxy Mobile IP (PMIP) tunnel for each PDN connection between the BBF BNG and the 3GPP PGW(s). At the setup of the GTPv2/PMIPv6 tunnel to the PGW, the BNG indicates the PDN type: IPv4-only, IPv6 only, or IPv4v6. The UE is not able or willing to indicate the IP capability it has. Therefore the BNG has to assume either a single IP type PDN connection type (e.g. Pv4ony or Pv6ony) or a dual IP type PDN connection type (i.e. IPv4v6) at tunnel establishment. If there is a mismatch between the UE IP capability and the network assumption, extra resources may be allocated unnecessary. This problem is solved in that the non-3GPP gateway node, e.g. the BNG, sends a message ((b)-(A)) to the 3GPP gateway node, e.g. the PGW, including an indication that the PDN connection is to support the first and a second version of the Internet Protocol, e.g. PDN type “IPv4v6”, with allocation ((C)) initially by the 3GPP gateway node of an IP address for the PDN connection of the first version but not the second version. Following establishment of the PDN connection, when the non-3GPP gateway node receives a second trigger message ((e)) relating to the PDN to trigger allocation of an IP address for the PDN connection of the second version, the non-3GPP gateway node sends a message ((f)-(E)) to the 3GPP gateway node to request the allocation of an IP address for the PDN connection of the second version and, if necessary, the updating of the existing PDN connection. The non-3GPP gateway node receives from the 3GPP gateway node the second version IP address ((H)-(g)) allocated by the 3GPP gateway node for the PDN connection. | 11-20-2014 |
20150063101 | 3GPP BEARER-BASED QOS MODEL SUPPORT ON WIFI - A method is disclosed for providing broadband access to a Packet Data Network (PDN) from a WLAN. A network node receives a request for a dedicated bearer from a PDN gateway, along with one or more Quality of Service (QoS) requirements. Responsive to the bearer request, the network node sends a request to an access point in the WLAN for load information indicative of a load of the access point, and receives the requested load information. Based on the load information, the network node determines whether the access point would be able to meet the one or more QoS requirements if the bearer request was granted. If the determining indicates that the access point would be able to meet the one or more QoS requirements, the network node creates the dedicated bearer between the wireless terminal and the PDN gateway according to the one or more QoS requirements. | 03-05-2015 |
