Abstract: A system and method for providing dynamic demand based management of traffic channel allocation in a mobile communications network providing high-speed circuit-switched data services. Traffic channel allocation for the data services is controlled dynamically by an InterWorking Function (IWF) which monitors the status of the associated buffers. The need for additional radio resources and the under-utilization of current radio resources is automatically detected by the IWF which respectively responds by initiating new traffic channel assignments via the Mobile Services switching Center or requesting the Mobile Services switching center deallocate an appropriate portion of the allocated radio spectrum.

Abstract: The present invention provides a method for operating a network system and a network system operated correspondingly for improving network resource reservations and allocations. Information included in signaling messages of a given protocol, like the resource reservation protocol (RSVP), which do not provide information about the actual communications status in the network. According to the invention, information concerning the communications/service quality of the network are collected from all over the network. In particular, such information is collected from all network domains and their routers, respectively. The collected information is communicated in the network by extending the signaling messages obtained on the basis of the given protocol. Utilizing the collected information, service quality negotiations between a server and its client are improved. This improvement can be achieved for network systems comprising a network domain serving a single client, and multicasting networks.

Abstract: A message is distributed from a source to one or more hosts in a communications network that comprises one or more multicast capable routers. To do this, a first multicast capable router generates a first table that identifies sub-branches connected to the first multicast capable router, and for each identified sub-branch, includes membership-related information from which it can be determined how many hosts are part of the sub-branch and (optionally) a metric associated with each of the sub-branch hosts. The multicast capable router then receives the message to be distributed and a first value, N1, that specifies how many hosts the message is to be distributed to, and uses the first table to identify N1 hosts and their respective sub-branches. It distributes the message to each of the identified sub-branches along with a second value that specifies how many hosts within the sub-branch the message is to be distributed to.

Abstract: The invention relates to a method for selecting transmission entities for supporting services within and between networks. The problem of selecting a transmission entity, taking as well a plurality of service parameter as a plurality of transmission entities into account, is solved by sending a request including a set of parameter to a number of transmission entities. The receiver of said request check, whether they support the requested service, or if they can offer an alternative. They transmission to different transmission entities is performed offering a number of alternatives.

Abstract: A telecommunications network architecture and method of providing failover operations between mobile switching centers (MSCs). A plurality of MSCs and at least one base station controller (BSC) are connected to an Internet Protocol (IP) network in which transmission paths and control paths are logically separated. The BSC reports to a primary MSC and includes an alternative MSC list identifying at least one backup MSC for the primary MSC. The BSC determines when the primary MSC has failed, and utilizes a control path in the IP network to notify the backup MSC that the BSC has switched its reporting to the backup MSC. The BSC also utilizes a transmission path in the IP network to send mobile station communications from the BSC to the backup MSC. Mobile station location updating requests are sent from the backup MSC to a home location register (HLR). The requests include a new element that informs the HLR that the backup MSC is now serving the mobile station due to a failure of the primary MSC.

Abstract: The invention relates to a traffic management system (TMSYS), which comprises a road network (RDN) on a physical layer (PL) and at least a packet switched control network (PSCN) on a traffic control layer (TCL). The vehicle traffic formed on the physical layer (PL) by a plurality of vehicles (C1-Cx) travelling along a plurality of road sections (RDS1-RDSm) of the road network is mapped into a packet traffic constituted by a plurality of packets (CP1-CPx) routed along a plurality of packet routing links. Packet control units (PCU1-PCUn) of the packet switched control network (PSCN) are adapted to control the packets (CP1-CPx) on a respective packet routing link (PRL1-PRLm) in the traffic control layer (TCL) to correspond to or simulate a respective vehicle (C1-Cx) on a corresponding road section on the physical layer (PL).

Abstract: The invention relates to a traffic management system (TMSYS) including a layered structure of management layers. The system comprises a physical layer (PL) on which the actual traffic takes place. A traffic signalling layer (TSL) controls the traffic on the physical layer (PL) and collects traffic information (TSI) about the vehicle traffic. A traffic control layer (TCL) comprises a packet switched control network (PSCN) for routing packets to correspond or simulate the vehicle traffic. A service application layer (SAL) provides special services to the traffic control layer (TCL) and/or the traffic signalling layer (TSL). A communication layer (CL) is used for communicating the information. Each layer comprises an exchange interface for receiving/transmitting information to one or more of the other layers. The layered structure of the traffic management system allows in particular a flexible adaptation, exchange or extension of functionalities provided in each layer.

Abstract: An Internet Protocol (IP)-based radio telecommunications network and method of providing data services to a mobile terminal. An Internet Protocol Shared Interworking Function (IP-SIWF) is implemented in the network, and is controlled from a Mobile Switching Center (MSC) utilizing the Media Gateway Control Protocol (MGCP) device control protocol. When a data call carrying a data payload is originated by a mobile terminal, the data call is transported utilizing radio access and radio link protocols to the IP-SIWF. The radio access and radio link protocols are terminated in the IP-SIWF, and the data payload is transported thereafter utilizing a real time protocol over a User Datagram Protocol (UDP) and an IP protocol layer.

Abstract: The invention relates to a messaging device, capable of sending information.

Abstract: A communication network element or part, and a method for operating a communication network part are disclosed. The communication network part comprises a first layer for transferring signalling information assigned to a telephone call being processed in the network and a second layer for transferring payload information assigned to the telephone call. An interface couples the network to a further network and comprises a signalling information exchange function and user or payload information exchange function between the network and the further network. The second layer generates an information frame which includes user information of the telephone call being transferred to and from the interface on a direct route assigned to the telephone call within the second layer and selectively suppresses the transfer of an information frame within the second layer if the information frame does not comprise any user information.

Abstract: The invention relates to a method for transporting physical objects, wherein at least one physical object is transported from a sending station to a receiving station, wherein the transport occurs through at least one physical router, wherein the physical router executes a decision about further parameters of transport to another physical router or to the receiving station.

Abstract: A payload data connection arrangement within a core network in a cellular mobile communication network reduces the number of transcodings and reduces the number of transmission devices that are linked in by a more flexible handling of interworking functions. This is achieved by comparing possible payload connections between a core network and access networks for both legs of a call. Based on the result of the comparison, only those devices are linked in that are technically necessary. Methods and devices that are used to set-up data connections with said benefits are illustrated and described.
