A method for simulating a mobile telephone network with shared-access channels. The simulation method includes the steps of simulating at least a first and a second configuration of the mobile telephone network that are statistically independent one from the other. Each one of the steps of simulating includes at least the steps of: determining a number of mobile terminals generating a packet data traffic; assigning to a list of mobile terminals included in the number of mobile terminals generating a packet data traffic, at least one shared-access channel of the mobile telephone network to be simulated; and performing a scheduling management algorithm of the list of mobile terminals on the shared-access channel.

Simulating a mobile network with shared access channels

A method of distributing information content to at least two user equipments includes: setting up a common downlink channel common to the at least two user equipments; setting up at least two uplink channels, each uplink channel being dedicated to a respective one of the at least two user equipments; delivering the information content to the at least two user equipments over the common downlink channel; and controlling transmission powers related to the common downlink channel and the at least two uplink channels in a closed-loop fashion. The closed-loop fashion power control includes: receiving from the at least two user equipments common downlink channel quality indications over the respective dedicated uplink channels; adjusting a transmission power in respect to the common downlink channel based on the common downlink channel quality indications received from the user equipments; evaluating a channel quality with respect to each of the at least two dedicated uplink channels; and based on the evaluation, sending to the at least two user equipments a transmission power control command over the common downlink channel.

Method and system for transmitting content to a plurality of users of a mobile communication network

A method of evaluating the performance of a mobile telephone network having at least a first and a second simulation of a first and a second network configuration, respectively, which are statistically independent of each other. Each simulation includes the following steps: specifying a total number of users to be simulated; determining a sequence of activation of user blocks included in this total number of users to be simulated and indicating a traffic distribution; activating said user blocks in succession until the total number of users to be simulated is reached; and processing at least one radio resource management event relating to the traffic distribution associated with each currently activated user block. The simulations are repeated until a predetermined accuracy threshold is reached for each simulated network value.

A scheme substantially similar to that used in HSDPA (in which a downlink channel is provided for data transmission, and at least one associated control channel is provided for transmission of control information including information related to availability of a portion of the transmitted data for the current UE on the downlink channel) is adapted for prolonged high data rate transmission, particularly for MBMS transmission. A duration of the data portions sent on the downlink channel is varied possibly up to high duration values (as compared with a duration of one TTI). User equipment enjoying the service is informed of the duration of the imminent available data portion in a field suitably defined and transmitted as control information on the associated control channel(s). Advantageously, during the 'long' decoding of the data portion, the UE does not monitor the associated control channel(s), so that the impact on the terminal's battery is considerably reduced.

A method for planning a cellular mobile telecommunications network includes at least one network cell and is intended to provide network services to users located in the network cell, wherein the method includes: a) setting a current provisioning rate to the highest of the provisioning rates; b) estimating a power required to the at least one network cell for providing the at least one network service in the service area at the current provisioning rate; c) comparing the estimated required power to a maximum power deliverable by the at least one cell; and, if the estimated required power exceeds the maximum deliverable power; d) reducing the service area so that the estimated power required to the at least one network cell for providing the at least one network service at the current provisioning rate in the reduced service area does not exceed the maximum deliverable power; e) updating the current provisioning rate to the immediately lower provisioning rate of said plurality, if any; and f) repeating steps b) and c) and, if required, steps d) and e).

Method for planning a cellular mobile telecommunications network

In a code division multiple access transmission system (CDMA), codes are generated according to a tree structure organized on a plurality of layers. Each re-allocation is considered as an access request to the system by a new user and the re-allocation codes are transmitted to each involved user through the respective re-allocation messages. Re-allocation messages to users having the same spreading factor (SF), and hence the same service bit-rate (kR) are substantially sent simultaneously, in order to reduce to a minimum the time required for the re-allocation operation.

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.
