Abstract: A method of communication between an electronic device and a cellular network employing a communication protocol is disclosed. The device initiates a connection with the network and during the initiation the device issues to the network at least one information criterion. Once the connection is established, the network forwards to the device only communications required by said communication protocol and any communications which meet the information criterion issued by the device.

Abstract: A method of communication over a cellular telecommunications network using an electronic device comprises communicating a session control signal between the electronic device and the cellular telecommunications network on a first radio channel provided by the cellular telecommunications network. The session control signal comprises identification data that identifies a remote party. The cellular telecommunications network uses the identification data to establish an IP-based communication session with the remote party. Content data for the IP-based communication session is communicated between the electronic device and the cellular telecommunications network on a second radio channel provided by the cellular telecommunications network.

Abstract: There are provided measures for supporting an authentication to an external packet data network over an untrusted access network, said measures exemplarily comprising authenticating a user equipment to a communication network providing connectivity for the user equipment across an unsecured access network in response to a first authentication request, wherein the authentication request is an authentication request of a key information exchange mechanism and includes authentication data, receiving a second authentication request for authenticating the user equipment towards a packet data network external to the communications network. The measures may further comprise creating a binding update message including the authentication data and identity information of the user received from the user equipment.

Abstract: A second internet protocol network is logically connected to a packet data network connection provided between a user equipment and a first internet protocol network over a radio access network, the second internet protocol network located on a data path from the first internet protocol network to the user equipment. The first internet protocol network represents the highest level internet protocol point of attachment to the packet data network connection. Router advertisements are sent from the second internet protocol network to the user equipment over the radio access network via the packet data network connection.

Abstract: There is provided a mechanism for establishing a single PDN connection with plural IP addresses and breakout or terminating points. When a communication connection provided with multiple IP addresses via a multi-address bearer connection is established, an indication is prepared for indicating a terminating point represented by a network element of the cellular communication network where data traffic, based on one of the multiple IP addresses, is branched to another network being different to the cellular communication network by means of an IP based communication link The indication element is sent to the communication network by means of a PDCP signaling e.g. as a new PDU type code. In the network, it is decided whether a local receiving network element is indicated as a terminating point, wherein in this case a breakout connection to another network being different to the cellular communication network by the IP based communication link is established.

Abstract: A method and apparatus for synthesized address prefix detection is provided. One example method includes generating a request for a first protocol address record of a name that has been assigned an address in accordance with a second protocol, causing the request to be sent to a domain name system server, and analyzing a response to the request for the first protocol address record to determine whether the domain name system server generated a synthesized address for the name in accordance with the first protocol. Similar and related example methods and example apparatuses are also provided.

Abstract: Various methods for determining network entity timeout values to improve keep-alive signaling are provided. One example method may comprise providing for transmission of a request for a timeout value associated with a keep-alive timer. The method of this example embodiment may further comprise receiving a response to the request, wherein the response comprises an indication of the timeout value of the keep-alive timer. Additionally, the method may further comprise determining an expiration time of the keep-alive timer based at least in part on the timeout value. The example method may further comprise providing for transmission of a keep-alive data packet prior to the determined expiration time. Similar and related example methods, example apparatuses, and example computer program products are also provided.

Abstract: A mechanism for routing in a network is described. The mechanism comprising receiving a request from a node; obtaining, based on the received request, an identifier relevant to said node; allocating a first local prefix; setting a first timer indicating a length of time the first local prefix or an address comprising the first local prefix is valid; setting a second timer indicating a length of time the first local prefix or the address comprising the first local prefix is preferred when the first local prefix or the address is valid; and sending a first message comprising said identifier, said first local prefix and said first timer to a network element.

Abstract: Apparatus, method, system and computer program product for server failure handling A mechanism for a first apparatus is described. The mechanism comprising receiving, from a first apparatus, a first authentication request comprising an user identity and an identity of said first apparatus, wherein said first apparatus being capable for provide authentication related service with respect to said user identity; determining if a third apparatus, originally associated with said user identity for providing authentication related service, is available for providing said service; registering said first apparatus as the server associated with said user identity for providing authentication related service, if said third apparatus is not available; sending a response to said first apparatus to acknowledge the first authentication request.

Abstract: In some aspects, the disclosure is directed to methods and systems for management of path selection and reservation between layer 3 devices, as well as path selection and reservation across L2/L3 boundaries. In one implementation, path selection can be managed by separating independent but “cooperating” layers, with layer 3 topology and non-adjacent layer 2 topologies handled separately. A first layer 3 router can be identified as a path computation engine (PCE), while other layer 3 routers can be implemented as path control clients (PCC(s)). One layer 2 PCE can be assigned per layer 2 topology, preventing competing path assignments and reservations.
