Patent number: 9065515Abstract: Method and system for improving the performance of mobile communication networks. The method and system employs the additional functionality whereby an additional phase offset can be applied to one of the physical paths (one physical antenna) in order to modify and adapt the transmit polarization. In the preferred embodiment, the criterion for selecting the additional phase offset will be to maximize the energy received from the HSPA serving cell by the legacy HSDPA user equipments.Type: GrantFiled: October 4, 2011Date of Patent: June 23, 2015Assignee: VODAFONE IP LICENSING LIMITEDInventors: Yannick Le Pezennec, Miguel Arranz Arauzo, Brendan McWilliams, Javier Lopez Roman, Julio Urbano Ruiz, Santiago Tenorio Sanz

Patent number: 8862132Abstract: A network component for a cellular network. The cellular network includes a plurality of access nodes covering a cell area and an access control node common to all access nodes for controlling the provision of traffic. The network component includes a communication manager and a classifier for classifying users of the cellular network into a first group of users and a second group of users. The communication managers checks if a call or an SMS is set up by a user belonging to the first or second group of users, takes control over calls and/or SMSs set up between users of the first group of users, and passes control to the access control node of the remaining calls and/or SMSs.Type: GrantFiled: October 27, 2011Date of Patent: October 14, 2014Assignee: Vodafone IP Licensing LimitedInventors: Miguel Arranz Arauzo, David Valerdi Rodriguez, Iñigo Güemes Cabrejas

Patent number: 8515492Abstract: A method and a system are described for adapting a service provided by a base station in a cellular communication network to mobile stations in its coverage area. The base station is supplied with energy from a renewable energy generator and/or from a back-up battery supply. The back-up battery supply is at least partially charged by the renewable energy generator. The service is adapted in terms of coverage and/or capacity provided to the mobile stations as a function of the stored energy in the back-up battery supply and/or as a function of a forecast regarding the amount of energy supplied by the renewable energy generator over a time period.Type: GrantFiled: July 1, 2010Date of Patent: August 20, 2013Assignee: Vodafone Group, PLCInventors: David Valerdi Rodriguez, Miguel Arranz Arauzo

Patent number: 8244314Abstract: Method and system for reducing the power consumption in mobile networks, wherein the communication between a mobile terminal and a base station is QAM modulated. The method comprises: making the base station a dynamic real time analysis of the QAM symbols used in the communication between said mobile terminal and the base station, detecting the most frequently used QAM symbols; obtaining the base station a new assignation of the QAM symbols for the downlink communication; sending the base station the new assignation of the QAM symbols to the mobile terminal; using the mobile terminal and the base station said new assignation of the QAM symbols for the demodulation process and modulation process, respectively, in their subsequent communication.Type: GrantFiled: June 30, 2010Date of Patent: August 14, 2012Assignee: Vodafone Group PLCInventors: Inigo Güemes Cabrejas, Miguel Arranz Arauzo, Alberto Gómez Coloma
