Patent ID: 7224968

Claim:
A method of providing performance information for a digital mobile communications network, the network comprising: a communications network infrastructure, the infrastructure having a plurality of elements, including a plurality of radio communications base stations, and having interfaces between said elements; and a plurality of mobile communications devices for radio communications with said base stations; communications between said mobile communications devices and said base stations, and signals on interfaces within the network infrastructure, comprising traffic and signaling data; the method comprising: collecting data on at least one parameter associated with a first data communications session of a said data communications device to provide measurement data; establishing a second data communications session for said mobile communications device; sending said measurement data from said mobile communications device into said communications network infrastructure using said second data communications session; reading at least signaling data for said first data communications session from a first of said network infrastructure interfaces; reading said measurement data from a second of said network infrastructure interfaces; correlating said signaling data for said first data communications session and said measurement data; and outputting a result of said correlating to provide said performance information.
