Abstract: This method is an improvement to a method used to enlarge the display of a first portion of a map, without hiding a first peripheral portion of this map. This improvement involves detecting an event which appears in said first peripheral portion (SPP4?). The improvement further involves defining a second portion to be enlarged (SPA5), centered on the position (BS2) of this event, defining a second peripheral zone (SPP5) associated with this second portion to be enlarged, displaying (SPA5?) the second portion to be enlarged (SPA5) by applying respective enlargement ratios greater than 100% to at least some elements of that portion, so as to make the event more legible, and displaying (SPP5?) the second peripheral portion (SPP5) by applying at least to some elements of this portion respective enlargement ratios lower than 100% so as to save surface area to avoid hiding a portion of the map.

Abstract: This method is used to enhance the display of a building (SC) showing several levels (T, F1, F2, F3) of this building, without hiding a portion of the map.

Abstract: A method of operating a mobile communication network includes defining at least one criterion of inclusion of network objects in at least one group of network objects also referred to as an object zone, constructing at least one object zone from network objects satisfying said at least one criterion and performing at least one radio network optimization operation using said at least one object zone constructed in this way.

Abstract: The method analyzes the operation of a cellular mobile telecommunications network comprising a set of cells each associated with a base station adapted to communicate with a mobile station present in the cell. The method comprises: a) for each cell, collecting one or more variables characteristic of the operation of the network in said cell; and b) supplying the or each characteristic variable in association with the collection cell. The supply step comprises: b1) selecting on a map of the network based on said cells an observation line passing over the map across adjacent cells; and b2) making available a structured representation of the or each characteristic variable for only the adjacent cells crossed by said observation line, in the order in which they are encountered along said line.

Abstract: The method is used to enlarge the display of a first portion of a map, without hiding a first peripheral portion of this map. This method includes detecting an event which appears in the first peripheral portion and defining a second portion to be enlarged, centered on the position of this event. A second peripheral zone associated with this second portion to be enlarged is defined and the second portion to be enlarged is displayed by applying respective enlargement ratios greater than 100% to at least some elements of that portion, so as to make the event more legible. The second peripheral portion is also displayed by applying at least to some elements of this portion respective enlargement ratios lower than 100% so as to save surface area to avoid hiding a portion of the map.

Abstract: A communication network diagnosis tool is adapted to analyze network analysis data using diagnostic trees consisting of nodes each associated with a network test or a set of network tests and connected together by branches representing logical relationships between tests to deliver diagnostic reports describing causes of problems in said network. The diagnostic tool comprises i) processor means adapted in the event of using at least a portion of a diagnostic tree for a test to associate with at least some of the nodes and/or links of said portion information data representing the result of the test on the node or link concerned and corresponding to selected levels of importance and ii) display means adapted to display selectively a graphical representation of the nodes and/or links of said portion representing at least a portion of the results of said test as a function of at least one selected level of importance.

Abstract: The workstation (10) comprises: a unit (14) for displaying at least one map comprising a background and a set of symbols distributed over the background; an interface (16, 18, 19, 19A) for enabling the user to select the appearance of the map; and control means (20) for controlling the display unit (14) to modify the appearance of the map as a function of an appearance selection made by the user by means of the selection interface (16, 18, 19, 19A). The interface includes means (19) for selecting the size only of at least one symbol. The control means (20) are adapted to cause the display unit (14) to modify the size of the or each symbol as a function of the size selected, without modifying the scale of the background of the map.
