A method for admitting calls to the mobile communication network in both uplink and downlink on the basis of the evaluation of the actual system load is also proposed. Preferred application is in UMTS mobile networks. | 12-25-2008 |
20080320526 | Video-Communication in Mobile Networks - A video-communication service in a mobile communication network using a packet-switched connection, in which a monitoring of a radio channel portion is performed at the mobile stations of the users involved in the communication. Parameters of the video communication (e.g. the coding rate) are adjusted based on a result of the monitoring of the radio channel portion. | 12-25-2008 |
20090075669 | METHOD OF OPERATING A WIRELESS COMMUNICATIONS NETWORK, AND WIRELESS COMMUNICATIONS NETWORK IMPLEMENTING THE METHOD - A method of operating a wireless communications network is adapted to provide services to users exploiting a first and a second different radio communications technologies, for example, an enhanced general packet radio service network. The method includes: providing, in a user profile available at the network, a subscription indication adapted to indicate that the user has subscribed for being provisioned with the network services through the first radio communication technology, upon reception by the network of a capability indication from the user adapted to indicate to the network that the user supports the first radio communications technology, looking up the user profile for the presence of the subscription indication; and in case the subscription indication is not found, handling the user as if supporting the second radio communications technology but not the first radio communications technology. | 03-19-2009 |
20090168683 | Method and System for Transmitting Content to a Plurality of Users of a Mobile Communication Network - 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. | 07-02-2009 |
20090305712 | Method and system for transmitting content to a plurality of users of a mobile communication network - 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. | 12-10-2009 |
20100035619 | METHOD FOR PLANNING A CELLULAR MOBILE TELECOMMUNICATIONS NETWORK - 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). | 02-11-2010 |
20100128806 | METHOD FOR PLANNING A DIGITAL VIDEO BROADCASTING NETWORK - A method and a system for planning a digital video broadcasting network in a geographic area of interest includes simulating an electromagnetic field propagation in a plurality of area elements of the area of interest; for at least one area element of the plurality, performing a decoding of the simulated radio signals which, as a result of the simulating, are received at that area element, and based on a result of the decoding, determining a service coverage in the area of interest, wherein the network is a digital video broadcasting-handheld network and performing a decoding of the radio signals includes changing a position in time of a decoding time window, in particular, for determining the position wherein the ration signal/noise is maximum. | 05-27-2010 |
20100278152 | Scheduling Method and System for Communication Networks; Corresponding Devices, Network and Computer Program Product - In a method of scheduling transmission services over a high speed packet access communication link such as a HSDPA and/or a HSUPA link a list of queues is created for transmission services to be provided over the link. The queues, which include both Real Time and Non Real Time queues, are allotted respective service priorities based e.g. on a channel quality indicator and/or a Quality of Service indicator to produce an ordered list of queues based on the service priorities. The link resources needed for serving at least one set of queues having higher priorities in the ordered list are estimated and a check is made. If these resources are available, the set of queues having higher priorities in the ordered list are served. If the resources required are not available, at least one queue is removed from the ordered list of queues. | 11-04-2010 |
20110176532 | METHOD OF TRANSMITTING DIGITAL SIGNALS, CORRESPONDING TRANSMISSION SYSTEM, SIGNAL AND COMPUTER PROGRAM PRODUCT THEREFOR - Digital signals are transmitted over a communication channel having a given bandwidth, by simultaneously transmitting: one or more Spread Spectrum signals, such as, Code Division Multiple Access signals, wherein the spectrum of the Spread Spectrum signals exhibits roll-off transition bands at the boundaries of the spectrum, and one or more multi-carrier transmission signals, such as, Orthogonal Frequency Division Multiplexing signals, which are transmitted over the transition bands of the Spread Spectrum signals | 07-21-2011 |
20130028220 | METHOD AND SYSTEM FOR HANDLING QUEUES IN COMMUNICATION NETWORKS, CORRESPONDING COMPUTER PROGRAM PRODUCT - In a communication network, a node receives from user equipment information on the length of a queue of information units to be transmitted to the node from the user equipment. The information, for possible use by the node in scheduling transmission of these information units from the user equipment, is in the form of quantized queue length information indicative of a lower bound and an upper bound for the queue length. Transmission of information units from the user equipment to the node is detected at the node, and an improved estimate of the queue length is produced by correcting the lower bound and the upper bound via subtraction of the number of the detected information units transmitted from the user equipment to the node. | 01-31-2013 |
