3.1 Definitions

For the purposes of the present document, the terms and definitions given in GSM 04.08 and the following apply:

CTS-idle mode: in this mode, the mobile station is not allocated any dedicated channel; it listens to the BCH and to the CCH when requested

NOTE: In CTS‑RR connected mode, main DCCH means FACCH.4 CTS-Radio Resource management procedures

3.2 Abbreviations

For the purposes of the present document, the abbreviations given in GSM 01.04 apply.

3.3 Random values

In a number of places in the present document, it is mentioned that some value must take a "random" value, in a given range, or more generally with some statistical distribution.

It is required that there is a low probability that two equipment’s in the same conditions (including the case of two equipment’s of the same type from the same manufacturer) will choose the same value. Moreover, it is required that, if it happens that two equipment’s in similar conditions choose the same value, the probability of their choices being identical at the next occasion is the same as if their first choices had been different.

The meaning of such a specification is that any statistical test for these values, done on a series of similar events, will obtain a result statistically compatible with the specified distribution. This shall hold even in the cases where the tests are conducted with a subset of possible events, with some common parameters. Moreover, basic tests of independence of the values within the series shall pass.

Data against which correlation with the values shall not be found are the protocol state, or the IMSI, or identities or other unrelated information broadcast by the network, or the current TDMA frame number.
