An in-for-the-long-haul series of discussions about CSA (cell site analysis) and highlighting all the wider area topics of CSA that seldom get discussed. The first three discussions can be found here

International Telecommunications Union and CSA

Were the standards to be made binding that could have political implications / ramifications regarding national sovereignty etc. However, a standard adopted by the ITU are called "recommendations". The recommendations carry a voluntary adoption by members states. The recommendations can though become directly or indirectly binding if it is incorporated into member states legislation where the legislation refers to a particular ITU recommendation. That would have a direct binding agreement. An indirect binding agreement could be where European legislation does not mention ITU recommendation per se but refers to CEPT or ETSI standards that become recorded that are in-turn derived from ITU recommendations. Were there to be an inextricable link requiring identical wording for CEPT/ESTI standard/ITU recommendation then that may amount to an indirect binding agreement with or to the ITU recommendation.

As this discussion relates to CSA and identified recommendations listed here ( http//cellsiteanalysis.blogspot.co.uk/2014/07/csa-survey-method-2.html ) the detail below highlights the radio subject matter from the division ITU-R.

Albert Einstein and Cell Site Analysis

Albert Einstein’s work has influenced and still influences, even today, mobility in cellular networks that we take for granted when applying cell site analysis. Mobile telecommunications is very lucky that it has a fantastic collection of grand luminaries whose influential work from the world of science and mathematics that underpins mobile communications. To understand Einstein’s influence it is useful to firstly understand the mobile radio background which CSA examiners, technicians and student can use to improve the art of performing cell site analysis. It does, though, require keeping a mindset to remain active at all times and that mindset is CSA needs to keep focused on how the mobile network is arranged to react to how the mobile phone is being used whilst moving around.

However, vehicular mobile usage is largely predicted within the network as "fast moving". Let us take the case of the getaway car speeding away from the scene of crime. Would it not seem strange to you to find the target's mobile phone call records identifying a number of Microcell IDs designed to cope with long dwell time in an area associated with slow mobile movements (e.g.5~10mph) compared with Macrocell umbrella coverage designed to handle accelerated speeds (e.g. 30~70mph). Why would the getaway car be driving so slowly after a crime, unless the *bogey wanted to be caught red-handed and why s/he commited the crime in the first place just to be arrested? On first blush of the call record evidence it wouldn't make sense.

CSA - Site Survey Method/LTE-UMTS SIBs

A highly defined smartphone etc can be offered services by a range of mobile network access systems e.g. GSM, GERAN, UTRAN, e-UTRAN etc when switched ON and actively in use or in idle mode. Access system information for LTE and UMTS are mapped in System Information Blocks (SIBs). When conducting ICCSA test measurement it is useful to identify which broadcasted SIBs contain data to help understand the survey results. Knowing the content allocated to SIBs can assist enormously in interpretation and when considering the propositions highlighted in the previous discussion thread

CSA - Site Survey Method/LTE SIBtype1

There are also benefits for those involved with cybercrime investigations.

Now readers could point out how would the person conducting the ICCSA know about the (H)eNobeB in the first place if call/data records are not available. For those situations where immediate is important aspect of current bandit surveillance the UE stores relevant information of the radio resources in an area for up to 3-hours after which old data are discarded. For a live UE acquisition this time frame could be useful. For a UE switched off (e.g. at the target site area) retains that information and requires extraction and harvest without invoking UE power up and network detection and registration.
