Abstract: Methods and nodes are provided for supporting session continuity for terminals capable of having simultaneous accesses while served by a plurality of gateways. Distinct binding cache entries (BCE) are stored for a terminal, each BCE being related to one of the gateways serving the terminal. The BCEs identify the terminal, provide an address allocated thereto for getting access at a gateway, and identify the gateway providing the access. When detection is made that two of more BCEs relate to the same terminal for distinct gateways, address information is sent to each other gateway.

Abstract: Methods and nodes are provided for efficiently establishing a route between a mobile node and a correspondent node in a Proxy Mobile Internet Protocol network. A return routability procedure is used between a local mobility anchor and a media access gateway on one hand, and the correspondent node on the other hand. The procedure is made without involvement from the mobile node. The procedure is such that the correspondent node handles return routability as per standard mobile IP mechanisms. Following this return routability procedure, a binding of an address of the mobile node with an address of the media access gateway is stored in the correspondent node. This binding allows data traffic to flow between the mobile node and the correspondent node without passing through the local mobility anchor.

Abstract: Methods, a data source and a router are provided to fragment packets that are to be sent in multicast mode towards a plurality of destinations comprised in a multicast group. Each router along a path leading from the data source towards some of the destinations sends its maximum transmission unit value in an uplink direction. Each router directly connected to the data source calculates a lowest maximum transmission unit based on various maximum transmission unit values received from downstream routers. The data source receives from each of the directly connected routers a maximum transmission unit value, which is certain to be acceptable to all routers and destinations of the multicast group downstream of that directly connected router. The data source selects a lowest one of the received maximum transmission unit values and fragments data contents accordingly.

A home address of the mobile node is not explicitly disclosed. An expected care-of address is calculated at the correspondent node and used by the correspondent node to send data packets to the mobile node.

Abstract: A method and a Mobile Node are provided for authenticating an Advertisement message received from an Access Router through an Access Point. The Advertisement message comprises a Hashed Nonce Value and a Nonce Index corresponding to a Nonce Value held in the Access Router. Upon receiving the Advertisement message from the Access Point, the Mobile Node initiates a process for configuring an IP address, by use of information received in the Advertisement, for having a session with the Access Point and the Access Router. In parallel, either the Access Point or the Mobile Node sends the Nonce Index directly to the Access Router. The Access Router replies with the Nonce Value sent to the Mobile Node. The Mobile Node hashes the Nonce Value received from the Access Router and compares a Result of the hashing with the Hashed Nonce Value. If the Result matches the Hashed Nonce Value, the Advertisement is considered authenticated and the IP address configured according to the Advertisement is kept in the Mobile Node.

Abstract: An edge node of an Access/Network Service Provider (ANP) network tracks the delivery into the ANP network of content from Contzzent Providers (CP), and generates accounting sessions with an accounting server. The edge node is provisioned with the IP addresses of known CP servers. A content delivery session, characterized by a CP IP address and a content identifier, such as a Differentiated Service Code Point (DSCP) value, is started upon the source IP address of a packet matching a known CP, and a packet count is incremented for each subsequent packet from the CP with the same content identifier. An accounting session is initiated with an accounting server when the content delivery session is started, and the accounting session is terminated, with the packet count for the session, upon a time-out since the last packet received. Multiple content delivery sessions may be ongoing simultaneously.

Abstract: A method and nodes are provided for registering a terminal. The terminal is capable of connecting in two distinct networks. The registration process for the terminal maps an identity and traffic handling policies of the terminal in a first network with an address prefix of the terminal obtained from the second network. The address prefix is obtained from the second network following authorization of the terminal in the first network. As traffic is exchanged between the terminal and a correspondent node while the terminal is accessing the second network, the mapping is used to ensure that policies for the terminal in the first network are applied in the second network.

Abstract translation: 提供了一种用于注册终端的方法和节点。 终端能够连接在两个不同的网络中。 终端的注册过程将第一网络中的终端的身份和流量处理策略映射为从第二网络获得的终端的地址前缀。 在第一网络中的终端的授权之后，从第二网络获得地址前缀。 由于当终端正在访问第二网络时，在终端和对端节点之间交换流量，所以映射用于确保第一网络中的终端的策略被应用于第二网络。
