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 (SPP'). The improvement further involves defining a second portion to be enlarged (SPA), centered on the position (BS) of this event, defining a second peripheral zone (SPP) associated with this second portion to be enlarged, displaying (SPA&#x2032;) the second portion to be enlarged (SPA) 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 (SPP&#x2032;) the second peripheral portion (SPP) 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.

Map display method

This method is used to enhance the display of a building (SC) showing several levels (T, F, F, F) of this building, without hiding a portion of the map. It consists of:

Map display method used to enhance the display of a building by showing several levels of this building

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.

Method and system for operating a mobile communication network

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: The supply step comprises:

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.
