Abstract

A management server of a cellular communication network comprises processing means for determining a quality of service map in at least some cells of the network from information sent to said network by at least some of the mobile terminals that have set up radio links within those cells, representing the value taken by at least one quality of service parameter on those connections, and identifiers of the cells in which the corresponding mobile terminals are situated.

Claims

1. A management server for a mobile communication network including cells in which mobile communication terminals may set up radio links, which server comprises processing means for determining a quality of service map in at least some of said cells from information sent to said network by at least some of said mobile terminals when they have set up radio links in said cells and representing the value of at least one quality of service parameter on said links and from identifiers of the cells in which the corresponding mobile terminals are situated and management means for defining a mapping strategy as a function of at least one configuration parameter.

2. A server according to claim 1, wherein said configuration parameter is chosen from a group comprising at least the designations of the cells covered by said map and/or the period of said mapping and/or the number of sending mobile terminals per cell and/or the sending period and/or the mobile telephone type(s) and/or the service type(s) used and/or the type(s) of customer/operator contract.

3. A server according to claim 1, further comprising interrogation means for generating at chosen times messages intended for at least some of said sending mobile terminals and requesting them to send said information.

4. A server according to claim 3, wherein said times are chosen as a function of each configuration parameter defining said mapping strategy.

5. A server according to claim 4, wherein said processing means determine each map by combining data of map portions associated with each cell concerned and said server further comprises storage means for storing data representing each map portion determined by said processing means in corresponding relationship to the associated cell.

6. A server according to claim 5, wherein said interrogation means store in said storage means each configuration parameter defining each mapping strategy.

7. A server according to claim 6, further comprising interface means for extracting data representing each map from said storage means and delivering it combined with data representing a map of the cells of said network for the purpose of the display thereof.

8. A server according to claim 7, wherein said interface means access said storage means to compare a map stored with the parameters defining the corresponding strategy to determine if said map corresponds to said strategy and then send the result of said comparison.

9. A server according to claim 8, wherein said interface means store in said storage means data representing the result of a comparison.

10. A server according to claim 9, wherein said interface means extract from said storage means data representing a comparison result for the purpose of the display thereof.

11. A server according to claim 7, wherein said interface means extract from said storage means data to be displayed associated with a time parameter representing their storage date.

12. A server according to claim 1, wherein each quality of service parameter is chosen in a group comprising at least the intensity of the signal received over a link, the value of an end-to-end performance measurement, the value of a bit rate available on a radio connection and the value of a mobile terminal calculation load and/or memory load.

13. A server according to claim 1, wherein some of the information sent to said network is information representing the position of the sending mobile terminal and said processing means determine at least some of said maps from said location information.

14. A server according to claim 1, wherein said processing means deduce speeds at which the mobile terminals are moving from the information that they send successively.

15. A server according to claim 14, wherein said processing means determine maps representing reception quality as a function of the speeds deduced.

16. A server according to claim 5, wherein some information sent to said network represents the sending mobile terminal type and/or version and/or the state of charge of the battery of said sending mobile terminal and said processing means determine at least some of said maps from said type and/or version and/or state of charge information.

17. A server according to claim 16, wherein said processing means store data representing said maps in said storage means in corresponding relationship to said type and/or version and/or state of charge and/or type of service used and/or type of customer/operator contract information.

18. A network management system for a mobile communication network including cells in which mobile communication terminals may set up radio links, said system comprising a management server according to claim 1.
