Method for determining the quality of mobile radiotelephone units in a mobile radiotelephone network

Attorney, Agent or Firm: Pillsbury Winthrop LLP
For each connection in a mobile radio network, at least one quality parameter is determined. A server (6) in a mobile radio network (7) calculates at least one statistical quality indicator (p.sub.i.) from quality parameters of multiple connections of a user, as well as at least one quality criterion (G, G.sub.i), which depends on a plurality of connections with different mobile devices (1). Based on the determined quality indicators, the server (6) decides which mobile devices (1) do not fulfil the quality criteria (G, G.sub.i) and must be rated as critical. The user of a mobile device, which does not fulfil one or more established quality criteria, is informed by means of an indication in his telephone bill. The quality parameters are determined in the base stations (2) of the mobile radio network (7) and collected in said server (6). The method may also be applied to the determination of the quality of components of the infrastructure, for example base stations (2). |

DETAILED DESCRIPTION What is claimed is: 1.
A method for determining the quality achieved by different components in a mobile radio network, comprising: determining a quality parameter which consists of a binary value indicating the success or failure of a connection through base stations of the mobile radio network for every connection with a mobile device; statistically calculating, by a server in the mobile radio network, a mobile device quality indicator of a mobile device from the binary quality parameters of corresponding multiple connections associated with the mobile device, wherein the mobile device quality indicator of the mobile device is determined as the success rate computed based on the proportion of the number of successful connections to the number of attempted connections; and determining quality criteria according to a quantile of the distribution of the success rates of the mobile device and/or a predefined limiting value with respect to the success rate, wherein a user of a mobile device is informed when the mobile device quality indicator associated with the mobile device does not satisfy the quality criteria.
2.
The method according to claim 1, wherein: the success rates of a mobile device are determined with respect to individual base stations based on connections made by the mobile device via the individual base stations and/or with respect to all base stations based on connections made by the mobile device via all base stations of the mobile radio network; and the quality criteria are determined according to a quantile of the distribution of the success rates determined based on connections made via individual base stations and/or all connections made via all base stations of the mobile radio network.
3.
The method according to claim 1, wherein the user of the mobile device that does not satisfy the quality criteria is informed by means of at least one of an indication in the telephone bill, an alphanumeric short message on the mobile device, and a verbal message transmitted to the mobile device
