There is assigned at least one first cost for expanding at least one link to a circuit-switched network that is part of a hybrid network comprising the circuit switched network and a packet switched network. All paths in the packet switched network are represented with a virtual link. A cost is assigned to the virtual link. An integer programming problem is solved to determine a number of links to add to the network, the integer programming problem having as inputs a model of the hybrid network and a demand forecast matrix.

Optimal expansion of a telecommunications network

In one of many possible embodiments, a method of locating a mobile terminal within a location area of a mobile communication network is provided. In the method, a threshold is set by calculating a sum of all location probabilities in the location area and dividing the sum by a maximum number of polling cycles allowed before the mobile terminal is located. Cells in the location area are arranged in non-ascending order according to their location probabilities. Multiple paging areas are formed one at a time by starting with a first cell not used in a previous paging area, grouping cells in order, and stopping when the total of location probabilities reaches the threshold or when no more ungrouped cells exist within the location area.

System and method for locating mobile terminals in mobile communication networks

Disclosed are methods and systems that can develop productivity scores for quantitatively comparing employees with somewhat different job task assignments. Evaluations of modeled task performance scores can be obtained and analysis of the evaluations, e.g., a regression analysis, can be performed to obtain performance parameters. The performance parameters can be applied to employee task performance scores over a time frame to obtain productivity scores for the employees. Statistical control charts based on the productivity scores can be used to identify outstanding and/or poorly performing employees.

Personnel productivity indices

The disclosed methods and systems prioritize network devices and components that more likely result in a network outage by evaluating their current and historical outage information relative to a dynamically-generated, statistical threshold based on such outage information. The prioritized list of network devices can be organized by, for example, quantity of outages, number of outage minutes, and/or number of customer-outage minutes so as to provide diagnosis sequences by type of network device, network location, type of component within the network device, and/or by operation during particular time periods/events.
