Abstract: A method of processing a model of a telecommunications network, the telecommunications network. The method includes dividing the network elements of the telecommunications network into a plurality of different groups, for a first of the group of network elements being modelled, loading computer program code representing the group of network elements being modelled into the computer memory and executing the computer program to model the first group of network elements within a first time period. For a subsequent time period the first group of network elements is represented by the amount of network services consumed on the one or more interfaces with the second group of network elements determined within the first time period, while loading into the computer memory computer program code to model the second group of network elements.

Abstract: A method for assessing performance of a cell in a network in which data is passed between layers in a protocol stack implemented by the cell. The method comprises calculating a data efficiency of data passing through a physical layer in the protocol stack via one or more higher layers in the protocol stack based on a comparison of a number of physical resource data units allocated to that data at the physical layer with a data throughput of one or more of the layers of the protocol stack. The method further comprises calculating an average efficiency by averaging the data efficiency over a predetermined time and normalizing the average efficiency with respect to a predetermined efficiency so as to generate a normalized average efficiency. The method also comprises comparing the normalized average efficiency with a target threshold and adjusting the operation of the cell if the normalized average efficiency differs from the target threshold by greater than a threshold amount.

Abstract: A radio network coverage area provided by a mobile radio network is analyzed. The analysis is provided by receiving control messages from a first interface communicated between a base station of the mobile radio network and a radio network controller, the control messages being provided for controlling the communications of the data to or from the mobile terminals via the base station.

Abstract: A method determined a routing of data between two network elements of a telecommunications network, which are interconnected via a transmission path. The method includes identifying plurality of layers of a telecommunications model from which the transmission path is comprised, and developing a reachability table by identifying a connection between each transmission element in each layer to other transmission elements in the same or a different layer of the transmission path.

Abstract: A method of processing a model of a telecommunications system including a plurality of access nodes through which communications terminals can communicate data is described.

Abstract: A General Packet Radio Service (GPRS) Accessed Extended Mobile Internet Protocol (EMIP) [G-EMIP] network is provided for wireless mobile device access to external packet data networks. Domains are defined to incorporate a subnet of standard GPRS and EMIP network entities accessed through a Domain Router. Packet access at the radio interface is provided using the base station portion of a GPRS network. Wireless link specific processing is relegated to this potion of the G-EMIP network. EMIP is utilized as a backbone network to provide mobility and service management and interconnection to external networks. A GPRS-IP Interworking entity (GII) interworks IP and GPRS protocols between GPRS and IP addressable network entities (i.e., translates messages of each protocol to corresponding messages of the other protocol). Mobility-related functionality is handled at the IP (network) layer.

Abstract: A pipeline communication system. The system uses the pipeline and the adjacent ground and includes branches with junctions. Governor modules and transformers/rectifiers form part of the network. Monitors periodically provide information to the network controller. The system control receives information by way of an outstation to provide two-way communication and control using the pipeline and adjacent ground as conductors. Typically, the information in the form of fast frequency shift keying modulation is superimposed on the cathodic pipe protection system.
