A method of managing a network apparatus of a telecommunication network, where the network apparatus does not expose management interfaces sufficient to allow managing at least one operational parameter thereof of interest for the managing, includes collecting data about the network apparatus to be managed by making requests to the network apparatus to be managed and to at least one other network apparatus in operating relationships with the network apparatus to be managed. Based on the collected data, generating a behavioral model of the network apparatus to be managed. The behavioral model is an inferred logical and mathematical model of the behavior of the network apparatus to be managed with respect to the operational parameter thereof of interest for the managing. The method also includes and managing the network apparatus to be managed exploiting the generated behavioral model thereof.

Method and system for managing telecommunication network apparatuses

A method assigning frequency bands on a cellular network including plural network nodes each configured to activate transmission links between pairs of corresponding network nodes to exchange traffic. The method includes, in response to assessment of a new transmission link to be activated between first and second network nodes: retrieving an indication of coordinates of first and second network nodes within a geographical area; retrieving an indication of resource sharing clusters, of the cellular network, each including a group of transmission links considered to potentially cause transmission collisions; selecting a set of the resource sharing clusters according to a comparison of coordinates of the first network node with coordinates of the network nodes corresponding to the transmission links of the resource sharing clusters; if the selected set of resource sharing clusters is not empty, carrying out operations including: activating a new transmission link by exploiting an assigned frequency band.

Method and system for limiting collisions in cellular networks

A cellular network comprising one or more user transceiver stations located within a first coverage area and that are each configured to provide radio coverage over a corresponding second coverage area by exploiting a selected frequency band among a respective set of frequency bands. When a user equipment within one first coverage area of requests to exchange user traffic, the cellular network selects a group of candidate user transceiver stations located within the first coverage area based on the position of the user equipment within the first coverage area; select a group of candidate frequency bands among sets of frequency bands of the user transceiver stations located within said one first coverage area; and allow the user equipment to exchange user traffic with one or more selected user transceiver stations exploiting a selected frequency band.

Multi-band cellular network with control plane decoupled from user plane

A cellular network is provided. The cellular network includes a plurality of control plane transceiver stations, each one configured to provide radio coverage over a corresponding first coverage area for allowing user equipment within said first coverage area to exchange signaling traffic with the control plane transceiver station. For each control plane transceiver station, the cellular network further comprises one or more hybrid transceiver stations located within the corresponding first coverage area. Each hybrid transceiver station is configured to be switched between: a) a user operation modality that allows user equipment within said user coverage area to exchange user traffic with the hybrid transceiver station, and b) a control operation modality that provides radio coverage over a corresponding control coverage area for allowing user equipment within said control coverage area to exchange at least signaling traffic with the hybrid transceiver station.

Cellular network with control plane decoupled from user plane

A method for managing power consumption of a radio access network. The method includes: defining a cluster including at least two radio resource units of the radio access network; defining a parameter indicative of a performance of the cluster and of a power consumption of the cluster, the parameter being expressed as a function of traffic throughputs carried by the radio resource units of the cluster; calculating optimum traffic throughputs as values of the traffic throughputs carried by the radio resource units of the cluster which optimize the parameter; and distributing traffic amongst the radio resource units of the cluster such that the radio resource units of the cluster carry the calculated optimum traffic throughputs.

Power consumption management in a radio access network

The radiation diagram of an antenna for serving a cell in a cellular communication network is selected from a plurality of available radiation diagrams by: classifying the plurality of available radiation diagrams in terms of a related radiation gain value; identifying for each one of the sectors a plurality of variations of the radiation gain value associated with the available radiation diagrams; estimating for each sector an initial value of at least one indicator of network operative functionality; estimating for each sector at least a desiderate value of variation of the related radiation gain value; and selecting at least one configuration that approximates the variation of the radiation gain value involving the desiderate value.

Method and system for selecting radiation diagrams of antennas for mobile-radio communication networks

The behavior of a network for mobile ratio apparatuses is simulated in a work station having a data input capable of inserting data representative of a network scenario, a data output capable of making available data representative of results of the simulation of the network, and a simulation environment associated with the computer and capable of simulating the network on the basis of the network scenario and of generating and sending to the data outputs the data representative of the results. This environment has first objects representative of devices and/or physical elements belonging to the network to be simulated and second objects representative of processing modules separate from the first objects and capable of conditioning and activating the first objects on the basis of the network scenario to simulate the network.
