Abstract: Methods, apparatuses, system and computer program product for activation and/or deactivation of bearers for a group of devices are disclosed. The method comprises receiving an attach request for a device belonging to a group of devices, obtaining an identity of the group of devices, allocating a first bearer identity for the group of devices, and sending the identity of the group and the first bearer identity to a first network element, wherein the first network element is involved in transmission of user data of the group of devices.

Abstract: A home agent is configured to be placed in a visited connectivity service network and configured to provide a possibility of a local break out of data. The home agent is configured to separate a first data traffic path and a second data traffic path. The first data traffic path is directly routed between the visited connectivity service network and the internet, and the second data traffic path is routed between the visited connectivity service network and a home connectivity service network, in order to minimize a number of hops and delay times. The home agent is configured to receive a routing policy from a home authentication, authorization and accounting server. The home agent is configured to route data traffic based on the received routing policy.

Abstract: An operational method interfaces a second communication network containing an access node with a first communication network encompassing a contact node. In a first step, an access node reads or receives an identity which is specific for the second communication network and is stored in a storage medium of a memory node. Then an interfacing message containing the identity that is specific for the second communication network is transmitted from the access node to the contact node, which is defined by an address stored in the storage medium. A packet data service to the access node is supplied by the contact node such that the second communication network is interfaced with the first communication network. An assembly and a storage medium are provided for interfacing the second communication network with the first communication network.

Abstract: Simplification of IMS registration in the event of emergency calls is made possible by apparatuses and a method for setting up an emergency-call connection from a terminal to an IMS via a network visited by the terminal, where, if the terminal is already registered in the IMS, setup of an emergency-call connection dispenses with IMS registration of the terminal in the IMS for this emergency-call connection if a comparison between a network identification for the visited network, of which the terminal was notified when it registered in the visited network, and a network identification for the terminal's home network reveals a match between these network identifications.

Abstract: Architecture, in particular a home agent being placed in a visited connectivity service network in order to separate a data traffic path to a home connectivity service network and a data traffic path to the internet in order to minimise a number of hops and delay times.

Abstract: In a method of selecting a communication network and connecting a mobile station into a communication network in a coverage area of which it is located, a mobile station is temporarily connected to a network unit of a first communication network, and sends a request relating to at least one second communication network to be used for communication via the network unit from the mobile station to a further network unit. After verifying the request by the farther network unit at least one response message containing at least one item of information is sent to the mobile station. The mobile station connects to a communication network depending on the at least one item of information received.

Abstract: In a communication network, which includes a call control level CCL, a resource control level RCL and at least one terminal A assigned to data transfer, a QoS requirement RQ determined for a data transfer is verified at expense at call control level CCL. An encrypted token T is then created from this and transferred via terminal A to resource control level RCL. This latter verifies an incoming QoS requirement RQ from terminal A only by means of the encrypted token T. If successful, the communication network is configured so that the data is transferred with the QoS verified according to the invention. The invention allows the efficient, secure and correct provision of QoS in integrated voice and data networks. In particular extensive modifications to existing routers are avoided at resource control level RCL. The regularly repeated transfer of tokens T also supports consistent termination of the QoS provided and secure and correct billing of the data transfer.

Abstract: An access data transmission independent of access data to a terminal and a terminal access data transmission to a service device are carried out by means of a transmission method (BRAS-ID/DSLAM-ID/ATM-VC-ID, Network-ID, Country Code-ID etc.). Said invention is characterised in that when identifying (1a, 1b) a terminal (terminal/DSL-modem/client) with respect to an access device (BRAS“/,,AAA”) of a telecommunications network (NGN-core-net), the terminal (terminal“/client”) receives and records a message (2) comprising access information and the (terminal“/client”) terminal, during a further contacting (,,SIP-emergency call-invite”/3.), transmits at least one part of said access information (3) to a service device (CSCF “and/or central emergency call 2”).

Abstract: The invention relates to a communication network, comprising a call control level (CCL), a resource control level (RCL) and at least one endpoint (A), associated with an information transfer, whereby a request (RQ) for a quality of service (QoS), determined for an information transfer is only exhaustively verified at the call control level (CCL). Subsequently, an encoded token (T) is formed and transmitted to the resource control level (RCL) by means of the endpoint (A). The above verifies a QoS request (RQ) coming from the endpoint (A), merely by means of the decoded token (T). Where successful the communication network is configured such that information with the QoS verified as above is transmitted. The invention permits an efficient secure and accurate provision of QoS in integrated speech and data networks. In particular extensive modifications to existing routers in the resource control level (RCL) are avoided.

Abstract: A cluster of traffic flow controllers comprises means for implementing a common registration database. Events relevant to registration that occur can be recorded in the traffic flow controllers of the cluster with the aid of said means. Said events and/or their consequences are then communicated to the other traffic flow controllers of the cluster.

Abstract: The functions associated with a control function are distributed on at least two units, a peripheral element and a communication management element. At least the access control function is assigned to the peripheral element and at least the communication management control is assigned to the communication management element. Additionally, the peripheral element comprises preferably a signalling proxy server for transmitting messages of the communication management element.

Abstract: In a virtual trucking process, call-related quality data is provided via IP-based networks. Said data is used to reduce the traffic in the IP network, based on its origin or route and potentially to divert said traffic, in order to maintain the voice quality of the existing and new calls at a sufficiently high level.

Abstract: Control units, such as e.g. gatekeepers, which operate according to the H.323 standard are protected against H.225 signalling overload by the denial of call requests that have no prospect of success according to the H.323 protocol specifications. This preferably occurs during the initial exchange of messages, which are configured according to RAS protocol specifications.
