Abstract: A method for accessing a wireless communication network is described, comprising collocating a Proxy Agent apparatus with an Access apparatus and determining in a Mobile Gateway apparatus an address of the Access apparatus. The Proxy Agent apparatus comprises information about a Master apparatus, the Master apparatus being adapted for executing a master function. The method further comprises indicating a message, to be handled by the master function, as a master function message and sending the master function message to the address of the Access apparatus. Furthermore, the method comprises diverting in the Access apparatus the master function message to the Proxy Agent apparatus and forwarding the master function message to a Proxy Relay apparatus for relaying the master function message to the Master apparatus.

Abstract: A method for protecting an authentication connection is described, comprising generating a first keying material by generating a first authentication connection, deriving from the generated first keying material a second keying material and utilizing the second keying material for protecting a second authentication connection.

Abstract: In order to transmit Ethernet transmission protocol-based data packets between at least one mobile communication unit and a communication system via generic route encapsulation tunneling established between a home agent unit and a foreign agent unit, at least one GRE key provided for establishing generic route encapsulation tunneling is linked to the media access control address assigned to the mobile communication unit.

Abstract: According to an example embodiment, a method may include sending, by a mobile station in a wireless network, a dynamic service addition (DSA) message to a base station, the DSA message identifying a packet data network (PDN) by access point name (APN). The method may further include exchanging data with the indicated packet data network via the base station.

Abstract: Apparatus and method for an efficient handover of at least one user equipment from a first access node to at least one further access node of a plurality of access nodes in a telecommunications system, said method comprising the steps of: said first access node, upon reception of a handover request from said user equipment, preparing a group of further access nodes of said plurality as possible target access nodes, upon attachment of said user equipment to said one further access node, said one further access node transmitting a message to said first access node, and upon reception of said message by said first access node, said first access node transmitting a further message to said possible target access nodes.

Abstract: A policy function used by a Service Flow Authorization of an Internal Protocol network is dynamically specified. A mobile station sends a request to a Network Access Servicer. Service Equipment forwards the request to a Service Provider's AAA Server. A connectively serving network sends an Access-Accept RADIUS message to an accessing serving network. The PF address is inserted into the Access-Accept RADIUS message.

Abstract: Various example embodiments are disclosed herein. In an example embodiment, a method may comprise receiving data from a home agent, wherein the data is directed to a mobile station that is coupled with a foreign network and the data includes an outer header having a foreign network address associated with the mobile station and an encapsulated header having a home network address associated with the mobile station; reading the encapsulated header to determine the home network address; and performing data classification using at least the home network address of the encapsulated header.

Abstract: A method and a device divert messages of a terminal, in particular, a mobile terminal from a first network provider connected to an access network by a gateway node of a second network provider. Network access identifiers are provided in the exchanged messages, made up of a character string for identifying the terminal and a character string for addressing a server of the network provider. The network access identifier is reformatted in the method such that the messages are not firstly transmitted to the server of the first network provider but rather to the server of the second network provider. After analysis of the data contained in the messages, the messages are then forwarded to the server of the first network provider after reverse formatting of the network access identifier.
