Abstract: The present invention relates to a method, signal and devices for facilitating distribution of multimedia broadcast multicast services, i.e. MBMS, in a telecommunications network by receiving an MBSM session start message from a broadcast/multicast service center; sending control traffic on a control network; sending as control traffic to a serving node an MBMS session start request message and including a common tunnel end-point identifier, i.e. common TEID, in the MBMS session start request message; receiving information from the serving node indicating the acceptance of using IP multicast; and sending media content on an IP multicast backbone to hosts that have joined the multicast group using the common TEID. If any part of the communication network does not accept the IP multicast backbone as distribution method tunnels will be used between the gateway and serving node and between the serving node and control node.

Abstract: The present invention relates to a system nodes and a method for enhancing security of end user station access to Internet and intranet(s), e.g. of corporate access, over access network access points, with gateway packet data nodes and packet data support nodes.

Router advertisements (RAs) from a routing arrangement to an end user station are sent with a controllable and variable frequency during an initial phase. During said initial phase, the frequency is higher at the beginning and lower at the end.

Abstract: Communication is enabled between a first network in which control functions and user functions are combined in a first node and a second network in which user functions are implemented in a second node, and control functions are implemented in a third node. A determination is made whether data received contains control data. If so the control data is extracted from the received data and is forwarded to the third-node in which control functions are handled. The control data is used for resource handling. The extraction and forwarding may be performed in the first, second, or third node, or at any surface in between. If the received data does not contain control data, the data will be forwarded to the second node. The first network may be a second generation data packet network, e.g., a Global Packet Radio Service (GPRS) network, and the second network may be a third generation packet data network., e.g., a Universal Mobile Telecommunication System (UMTS) network.

Abstract: Per-packet billing for a packet data network, mobile or fixed, is provided by retrieving and processing all packets transported at a physical layer of the network, where the data packets are communicated with a traffic function that operates independently of a billing function. Using a billing-function computing resource, which is separate and independent from a traffic-function computing resource that processes traffic related information, the billing data are filtered out, processed, stored and distributed, without competing with the traffic functions of the network. Two independent physical layer interfaces separately couple a communication link of the physical layer to the billing-function computing resource and traffic-function computing resource, respectively.
