Abstract: The method for distributing wireless audio and video signals indoors comprises receiving broadband signals in a radio access node (101) which transmits and receives wireless signals to and from at least one client device (110); the method is characterized in that the radio access node (101) processes the received signals and generates a new modified DVB-T type signal in the 5 GHz band, so that the spectral power density of the modified DVB-T type signal is at least 4 dB greater than the IEEE 802.11n signal which uses the same frequency band. This allows reliably sending interference-resistant audio and video signals, ensuring coverage, monitoring and remote configuration of the system used and ensuring quality of service.

Abstract: The invention relates to a method for preparing an optimal alternative billing plan for mobile telephony users managed through a call center, which is applicable to the recommendation of an optimal telephony plan to the customers of an operator, considering the consumption of the customer, the risk of the customer migrating to another and the market strategy of the operator. It comprises the estimation of the real bill of a customer during a time period covering the last M months, a simulated estimation of the bill of the customer using any generic plan based on the mean traffic of the last M months, applying a simulation algorithm and the estimation of the churn risk of a customer according to the value of the said customer, the value of the operators on the market, number of better offers, number of the customers which he calls per operator and the simulations performed with the generic plans, applying an estimation algorithm.

Abstract: The invention relates to a collaborative system for security information exchange between users, based on the fact that a determined function (whether storing or processing) is spread out at different points of a network to achieve more scalable processing and storing factors than if they were all done at one and the same point. The invention proposes architecture with a centralized element, referred to as “Central Device”, through which said user devices share information with the remaining users to finally activate an alert or rule it out.

Abstract: The invention relates to a method for gender identification of a cell-phone subscriber. There are two main steps: constructing a general model of female and male calling behaviour from a set of variables obtained for each subscriber; and classifying an individual calling behaviour of a subscriber comparing it with the general model. The method includes the step of constructing the general model comprises obtaining a set of data, that may be obtained from calling detail records, that are saved at a database every time a subscriber makes or receives a phone call; computing a set of variables using a set of instances from subscribers who their gender is already known; and applying an algorithm which generates groups labelled as male or female behaviour. Finally, in the step of classifying, the gender of the subscriber is identified by assigning to the subscriber the label of the closest group.
