Patent ID: 8631141

Claim:
A method comprising: logging data of several steps of a protocol hierarchy within a communications system for mobile radio and/or mobile telephones, wherein the data includes payload data and control information, wherein the control information are assigned to the individual protocol-hierarchy planes, each individual protocol-hierarchy plane being of a different hierarchal plane, wherein the control information of all protocol-hierarchy planes is buffered, wherein a maximum of one copy of the payload data is buffered, wherein the control information is logged in the individual protocol-hierarchy planes, wherein only newly arising information is buffered in the individual protocol-hierarchy planes, wherein the payload data and the control information are buffered in separate files, wherein references pointing to the buffered payload data and references pointing to the buffered control information of other protocol-hierarchy planes are buffered with the control information of the individual protocol-hierarchy planes, and wherein the payload data are buffered only in an uppermost plane of the protocol-hierarchy planes.
