Abstract: A method for a cellular telecommunications network includes selecting a plurality of cells, retrieving neighbor lists for the plurality of cells, determining neighbor collisions from the neighbor lists, and changing an identifier for a first cell of the plurality of cells based on a portion of the neighbor collisions that are associated with the first cell.

Abstract: Systems and methods are described for reducing an interference level associated with frequency drift in a wireless base station. The base station monitors an interference level in a frequency resource caused by a first frequency resource colliding with a second frequency resource. If the interference level is outside of an expected range, the base station adjusts a parameter of the base station such as a reference oscillator frequency to compensate for frequency drift. This method may be used in a femtocell wireless base station.

Abstract: An approach for using multiple menus with a graphical user interface is disclosed. A multiple menu comprises a menu panel with two or more selection regions, each of which is associated with a base menu. A user requests the menu panel without selecting a menu object displayed on a display unit, such as by right-clicking. The menu panel is displayed along with one base menu, and other base menus are displayed by the user moving the cursor to another selection region. The user selects a menu item from a base menu to cause the application to execute the function associated with the menu item. The selection regions of the menu panel do not include information describing the content of the associated base menus. By arranging the base menus around the menu panel, cursor movement is minimized to improve user efficiency in using the application.

Abstract: A system and method are described for dynamic temperature calibration of a frequency reference in a wireless base station. In a consumer grade base station, a reference oscillator may encounter frequency drift as the temperature of the base station changes. This causes interference as the transmission signal is not synchronized with other frequency resources in a network. An improved method of calibrating a reference frequency includes measuring a frequency difference between a frequency derived from an accurate reference frequency in a first base station and a frequency derived from a less accurate frequency reference in a second base station, determining a calibration factor for the offset, and applying the calibration factor to the base station to correct frequency drift. The calibration factors may be correlated with an operating temperature of the base station and stored in a temperature calibration table in the base station device.
