20150085681 | CELL PERFORMANCE ASSESSMENT - 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 normalising the average efficiency with respect to a predetermined efficiency so as to generate a normalised average efficiency. The method also comprises comparing the normalised average efficiency with a target threshold and adjusting the operation of the cell if the normalised average efficiency differs from the target threshold by greater than a threshold amount. | 03-26-2015 |
20140355484 | Self-Organising Network - A method for optimising a self organising network comprising a plurality of cells. The method comprises monitoring performance measurement data indicative of performance of one or more cells in a group of cells in the network, and monitoring trace data indicative of traffic statistics within the cells of the group. The method comprises generating, from the performance management data and the trace data, a plurality of key performance indicators each indicative of performance of an aspect of a cell in the group, and processing the key performance indicators so as to generate a hotspot value indicative of general performance of the cell in the group. The method comprises comparing the hotspot value with a threshold hotspot value, and if the hotspot value is greater than the threshold hotspot value, processing attribute data from the cells in the group so as to generate cause data indicative of a cause associated with the hotspot value exceeding the hotspot threshold value. The method also comprises generating, from the cause data, recommendation data for modifying an attribute of the network, and modifying the attribute of the network based on the recommendation data. | 12-04-2014 |
20120113821 | MODELLING APPARATUS AND METHOD - 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. For each connection defining a set of communications parameters which define a cost of communicating data via the connection and allocating a weighting value for communicating data via the connection, for all possible routes between the two network elements along the transmission path via each of the layers modelling the effect of the connection for routing the data in accordance with the set of communications parameters for the connection and determining a weighted result along each path, and combining the weighted results to determine a metric of performance for each of the possible routes. An optimum route can then be determined for routing data in accordance with for example a minimum cost metric. | 05-10-2012 |
20120093029 | MODELLING APPARATUS AND METHOD - 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. The method includes dividing the communications terminals, the access nodes and the core network into different groups, for a first of the groups loading the computer program code representing the communications terminals, the access nodes or the core network of the first group into the computer memory and performing the representing with the processor within a first time period, determining an amount of the data communicated between the first group and one or more of the other groups during the first time period, and for a subsequent time period representing the first group by an amount of data corresponding to the amount of the data communicated between the first group and a second of the groups, whilst loading the computer program code into the computer memory and performing the representing of the second group within the subsequent time period. The results produced by the modeling can be used to configure the telecommunications system itself. | 04-19-2012 |
20120072200 | MODELLING APPARATUS AND METHOD - 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, whilst loading into the computer memory computer program code to model the second group of network elements. In this way, an improvement in modelling telecommunications networks is provided by dividing each of the component parts of the telecommunications network into groups, and handling these groups on a cyclic basic. | 03-22-2012 |
20120039191 | ANALYSING RADIO NETWORK COVERAGE - A radio network coverage area provided by a mobile radio network is analysed. 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. The method includes identifying a mobile identity number associated with the mobile terminal from the control messages communicated via the first interface, identifying, using the mobile identity number, mobility control messages communicated via the first interface, the mobility control messages providing an indication of a relative distance of the mobile terminal from the base station, receiving data communicated via a second interface between the radio network controller and a core network part of the mobile radio network, identifying the data communicated from the mobile terminal, using the mobile identity number identified from the first interface, determining a relative measure of quality of the data received from the mobile terminal, and generating a performance map providing a relative distance of the mobile terminal from the base station and a quality of data communicated at the relative distance from the mobile terminal. | 02-16-2012 |
20110296031 | COMMUNICATIONS SYSTEM AND METHOD - A communication system is arranged to provide a communication service to a communication terminal. The communication system comprises a packet data network arranged to communicate data packets supporting the communication service to and from the communication terminal via a data path through the packet data network, a path computational element arranged to control the data path, an application server arranged to control the communication service and an internet multimedia sub-system operable to control the application server. The application server is operable to provide the communication service to the communication terminal in response to a registration request transmitted from the communication terminal to the internet protocol multimedia sub-system requesting an establishment of the communication service.
