Abstract: Methods of operating a network node in a wireless local area network, a mobile terminal and a server, respectively, are disclosed. Corresponding computer programs, as well as a network node, a mobile terminal and a server are also disclosed. The network node establishes connection with the mobile terminal; and sends at least one network name to the mobile terminal, wherein the at least one network names correspond to possible public land mobile networks, PLMNs, based on the determined AAA information. The mobile terminal can thus display the network name.

Abstract: The embodiments herein relate to a method in a location information node (327) for providing location information associated with a home base station (345) to a PCRF (350). The node (327) is dedicated to handling the location information. When the home base station (345) sets up an IPSec tunnel with a SeGW (332), the node (327) receives the information from the AAA server (330). The node (327) transmits the information to the PCRF (350) via the MME/SGSN (325, 340) using an interface between the MME/SGSN (325, 340) and the PCRF (350), or to the PCRF (350) via the MME/SGSN (325, 340) and a SGW/PGW (343, 348) using a S11/S4 interface, a S5/S8 interface and a Gx/Gxx interface, or directly to the PCRF (350) using an interface between the node (327) and the PCRF (350).

Abstract: Methods and related systems for controlling communication between Network Virtualization Edges (NVEs) in a network virtualization domain are provided. The methods generally involves generating and transmitting, by a Network Virtualization Authority (NVA), a list of participating NVEs to the NVEs comprised in the list, and the selective processing by the NVEs of messages received from other NVEs. By limiting NVE to NVE communication only to NVEs comprised in the list, attacks on the network can be mitigated.

Abstract: A QoS based selection of access network allows a UE to transmit different data traffic flows using different access technologies. The selection is done in accordance with information provided in the ANDSF. This allows a network operator to determine how different data traffic is routed, which can allow for better network utilization planning.

Abstract: The present invention relates to a method for closing all network connections to a detached user equipment. The local mobility anchor (LMA) receives and reads a control message saying that the user equipment is detached and all the network connections must be closed. The LMA performs the instructions in the control message, i.e. closes all the network connections to the user equipment. After the instructions have been executed, the LMA sends an acknowledgement back to indicate which actions have been performed. Thus, the closing of all network connections is done using only one message exchange and thereby saving signalling in the Core Network.

Abstract: The invention relates to a method of operating a network node in a telecommunication network, such as an MME. The method comprising: initiating a PDN connection revocable deletion procedure for a device when at least one predetermined criterion is fulfilled; sending a PDN connection revocable deletion request to another network node; receiving a PDN connection revocable deletion response message from said other second network node; and storing data indicating that a PDN connection with said device is revocably deleted.

Abstract: Systems and methods allow 3GPP and non-3GPP access with interworking between GTP-based networks and PMIP-based networks. For handover attachment of a UE, an IWP can be provided the address of the PGW which was used in the initial attachment of the UE so that, for example, an IP address can be maintained for an ongoing data connection established with the UE. Alternatively, the same IWP can operate as the proxy for all data connections with the UE such that the IWP is aware of the PGW used for the initial attachment and can reuse the same PGW for handover.

Abstract: Systems and methods for differentiating between a duplicate MAC address situation and a multiple MAC address movement situation are provided. A node receives a new MAC address determines if it is a known or unknown MAC address by comparing it with a stored MAC address table. If it is a previously known MAC address, the node initiates a duplicate MAC address detection process to determine if at least one of the duplicate MAC addresses is no longer valid or is the result of a MAC mobility event.

Abstract: A mechanism to permit an LMA to perform some specific handling once MAG restart is detected is disclosed. If a MAG restart is detected by the LMA, the LMA preferably will not release all corresponding binding in its cache. The LMA may select an alternative MAG which is servicing the same. Then the LMA can send a mobility message to the selected MAG. The mobility message can be triggered by the restart detection or by the received downlink data on one or more valid binding. The mobility message can contains all UE identity that has a valid binding in the LMA and the restarted MAG.

Abstract: 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.

Abstract: The network resources allocated to Machine Type Communication (MTD) devices (also referred to as Machine-to-Machine (M2M) Devices) can be reduced through the introduction of a new device state in a network. The network device state, referred to as a sleep state, allows the network to offload context information about the device to another network element so that the resources allocated to the sleeping device can be released. When the device needs to be contacted by a network element, the stored context information can be retrieved to facilitate paging the otherwise offline device.

Abstract: When a mobile device attaches to a non-3GPP network, it performs an AAA procedure with a 3GPP AAA. In addition to standard AAA process, the 3GPP AAA can perform a lookup based on information associated with the 3GPP AAA interactions to determine an appropriate vPLMN ID and v-ePDG address associated with the user equipment location. This information can then be provided to the UE so that its connection to the network can be appropriately configured.

Abstract: Modifications to authentication and authorization messages are used to allow an authentication server to query both an access network and a terminal device connecting over the access network to determine whether both nodes support the terminal device forming a plurality of packet data network connections that can support tunnels. This allows a non-3GPP access network to offer terminal devices the ability to connect to a 3GPP core network with multiple connections.

Abstract: In one aspect, the teachings herein propose a procedure provided by an appropriately configured 3GPP Core Network (CN), which allows External Identifiers to be provisioned dynamically by the 3GPP operator or an MTC service provider, using the existing 3GPP M2M architecture. As such, these teachings can be understood as providing for automatic activation, modification, deactivation, etc., of MTC service subscriptions or services, using protocol-based signaling between the involved entities, e.g., between a 3GPP HSS and an MTC Server (a Services Capability Server or SCS) and/or an MTC Bootstrapping Server that provides for MTC subscription activations, modifications, cancellations, etc.

Abstract: 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.

Abstract: Methods and Gateways (GWs) are provided for efficiently sending a router advertisement message to a User Equipment (UE). The GW comprises an interface, a processor, and an instructions repository that stores instructions that when executed by the processor cause the later to determine the UE is in idle mode, and responsive thereto, to delay a transmission of the router advertisement message to the UE until the UE transitions from the idle mode to an active mode. This is achieved by delaying a paging of the UE. In another embodiment, a method and GW is provided. The GW's processor detects a router advertisement message needs to be sent to the UE, determines the UE is in idle mode and delays a paging of the UE until detecting the UE transitions from the idle mode into an active mode, when the router advertisement message is sent to the UE.
