Dimensioning a policy and charging rules function (PCRF) of a communication system comprises: determining a number of processing nodes of the PCRF at a time; determining a first transaction parameter indicating a number of transactions per second exchanged by the nodes at the time; determining a load parameter indicating processing load of the nodes at the time; based on the first transaction parameter, the load parameter, the number of nodes, and allowable processing load that the nodes are set, determining a second transaction parameter indicating a number of transactions per second expected for exchange at the time by the nodes set at the allowable processing load; forecasting the first and second transaction parameters for a following time thereby obtaining forecasted first and second transaction parameters; and determining a number of nodes required at the following time according to the forecasted first and second transaction parameters.

Method for dimensioning a PCRF module of a communication system

A method upgrading a core section of a packet switched mobile network, includes: a) collecting information about a maximum signaling transaction amount managed by nodes of the core section with respect to active data connection established between user equipment and the packet switched mobile network, and calculating a corresponding active users parameter based on the collected information; b) retrieving an indication of how the maximum signaling transaction amount managed by the nodes is distributed among user equipment attached to the packet switched mobile network, and calculating a corresponding activity parameter based on the retrieved indication; c) calculating a forecasted number of user equipment which potentially can attach to the network in a future predetermined period; d) calculating a signaling traffic estimation based on the active users parameter, the activity parameter, and the forecasted number of user equipment, e) setting up the core section based on the calculated signaling traffic estimation.

Estimating signaling traffic in mobile networks

A method of providing telecommunication services includes generating fictitious contact information univocally associated with a telephone number assigned to a subscriber; and storing the fictitious contact information in a database, like an ENUM database. Responsive to a request, received from a requester, of a contact information corresponding to the telephone number and adapted to allow contacting over the Internet the subscriber assignee of the telephone number, the method includes having the database providing the fictitious contact information; and conditioning a resolution of the fictitious contact information for the provisioning of the contact information to the satisfaction of at least one security rule adapted to assess properties of at least one among the requester and the request. In a case that the request from the requester satisfies the at least one security rule, the method resolves the fictitious contact information and provides the requester with the contact information.
