Abstract:
1. A method implemented by an apparatus for gathering statistics relating to detected random accesses in a cell of a cellular radio communication network, wherein a random access includes transmission of a random access preamble code selected among a plurality of random access preamble codes used in the cell, said method including the step of: gathering statistics, per random access preamble code, relating to random access detections associated with one or more random access preamble codes used in the cell; wherein each random access preamble code is defined by a combination of a preamble scrambling code and a preamble signature and wherein at least one preamble scrambling code and a plurality of preamble signatures associated with each of said at least one preamble scrambling code are configured for use in the cell; and wherein said statistics gathering step includes registering, per random access preamble code, at least one of detected random access preambles and random access failures associated with said one or more random access preamble codes.
