The present invention provides apparatuses, methods, computer programs, computer program products and computer-readable media regarding Ultra High-Speed Mobile Network based on Layer-2 Switching. Certain aspects of the present invention include receiving, at a first gateway, a data packet from a first host served by the first gateway destined to a second host served by a second gateway, the data packet having a header comprising a layer 3 destination address of the second host and a broadcast layer 2 destination address, searching, by the first gateway, a flow table stored in the first gateway for an identity of the second gateway associated with the broadcast layer 2 destination address, if the identity is found in the flow table, replacing the broadcast layer 2 destination address with the identity of the second gateway serving the second host, and transmitting the data packet to the second gateway.

Network insights may be useful in various communication networks. For example, certain cellular or similar networks may benefit from the delivery of cellular network insights to subscriber devices through service set identifier (SSID). A method can include detecting, by a device, at least one advertised value of non-cellular access, wherein the at least one advertised value is received by the device over a cellular system information block message. The method can also include extracting, from the at least one advertised value, at least one cellular network insight for a cellular network condition.

A method of control plane messaging between a user equipment and a network element in a core network in which Non-Access Stratum protocol layer messages are sent in a Non-Access Stratum protocol layer wherein an Ethernet convergence sublayer is provided between the Non-Access Stratum protocol layer and a radio protocol layer. Systems, apparatuses, and computer program products for control plane messaging are also provided.

There is provided a charging control mechanism allowing flexible charging in specified communication areas of a communication network, for example of a WLAN. When it is detected that a UE tries to access in a specified communication network area, a charging setting to be used for a communication in the specified communication network area is determined and a rating information in the form of a rating attribute is included in each CDR for indicating the charging setting to be used for charging a communication of the UE in the specified communication network area. A rating/charging engine uses the rating attribute for determining the charging amount for the communication.

Charging mechanism for communication network

There is provided a method comprising estimating bit rate information for first traffic if said first traffic were to be routed between a user equipment which is attached to a first network and a network access point of a second network and determining if said first traffic is to be routed between said user equipment and said network access point in dependence on said estimated bit rate information.

Methods and apparatus for managing communications network loading

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.

Method for the transmission of ethernet transmission protocol-based data packets between at least one mobile communication unit and a communication system

A user terminal is switched between a cellular network and a worldwide interoperability for microwave access radio network within a telecommunication system. An authentication, authorization and accounting (AAA) server which is designed for use with both of these networks is disposed in the telecommunication system in such a way that user data of the user terminal stored in the AAA server can be accessed from both of these networks, thereby advantageously ensuring uninterrupted switching between the two networks free of loss.

Telecommunication system and method for controlling switching of user terminal between two networks

After a radio link is established between a mobile subscriber terminal and an access network, to authenticate the subscriber an authentication proxy server of an intermediate network forwards at least one authentication message containing a subscriber identification between the access network and a home network of the subscriber. If authentication is given by an authentication server of the home network, the authentication proxy server of the intermediate network stores the subscriber identification. The home agent receives a registration request message originating from the subscriber terminal and containing a subscriber identification; the home agent transmits a key request message, containing the subscriber identification, for a mobile key to the relevant authentication proxy server. The authentication proxy server provides a mobile key for the home agent, if the subscriber identification contained in the key request message matches one of the subscriber identifications that has been stored by the authentication proxy server.

Method and server for providing mobility key

The invention describes a method for transmission of a DHCP message between a telecommunication network, especially a telecommunication network according to the WiMAX-standard, and an Internet Protocol (IP) subscriber (SS/MS; MN) to the telecommunication network. Therein, an information secured with an encryption key is added to the DHCP message. The encryption key is derived from a basic key being provided by a network component of the telecommunication network.

A mobile station is designed, as a gateway for one or several mobile terminals, to establish a connection between the mobile terminal(s) and an access network. The mobile station supports a network-based mobility management such that the mobile station acts as a client instead of the mobile terminals during communication with a home agent of a home network or intermediate network connected to the access network in the framework of a mobile IP connection.

Information is transmitted in a communication system having at least two communicating devices using a link between the at least two communicating devices provided at least via a radio communication interface of a radio communication system having a number of base stations that are interlinked via a base station network. The link is realized using channels arranged in hierarchical protocol layers. Channel-specific information is given to a hierarchical higher channel at least from one channel for the radio link between a communicating device and at least one base station. This hierarchically higher channel is an Internet protocol-based channel for the overall link between the at least two communicating devices.

A first network is structured according to a first technology, especially a data network, comprising one or several network devices and/or interfaces, which are configured to establish communication with at least one station using the first technology and have basic functions for autonomous operation of the first network. In order to be able to collect subscriber-related data from a data source outside the network, especially a second network structured according to a second technology, more particularly a cellular mobile telephone network, when a subscriber who is not registered in the first network is connected, one of the two networks generically enables logical functions of components of the other network. A network facility enables the implementation of the above-mentioned method.
